A Surgical Safety Checklist to Reduce Morbidity and Mortality in a Global Population
By: Haynes, AB; et al.
The New England Journal of Medicine
Background: Surgery has become an integral part of global health care, with an estimated 234 million operations performed yearly. Surgical complications are common and often preventable. We hypothesized that a program to implement a 19-item surgical safety checklist designed to improve team communication and consistency of care would reduce complications and deaths associated with surgery.
Methods: Between October 2007 and September 2008, eight hospitals in eight cities (Toronto, Canada; New Delhi, India; Amman, Jordan; Auckland, New Zealand; Manila, Philippines; Ifakara, Tanzania; London, England; and Seattle, WA) representing a variety of economic circumstances and diverse populations of patients participated in the World Health Organization's Safe Surgery Saves Lives program. We prospectively collected data on clinical processes and outcomes from 3733 consecutively enrolled patients 16 years of age or older who were undergoing noncardiac surgery. We subsequently collected data on 3955 consecutively enrolled patients after the introduction of the Surgical Safety Checklist. The primary end point was the rate of complications, including death, during hospitalization within the first 30 days after the operation.
Results: The rate of death was 1.5% before the checklist was introduced and declined to 0.8% afterward (P=0.003). Inpatient complications occurred in 11.0% of patients at baseline and in 7.0% after introduction of the checklist (P<0.001).
Conclusions: Implementation of the checklist was associated with concomitant reductions in the rates of death and complications among patients at least 16 years of age who were undergoing noncardiac surgery in a diverse group of hospitals.

Syringe Reuse Among Infection Control Lapses Leading to 33 Outbreaks
Forty outbreaks in hospital and non-hospital settings are examined in a recent study by the Centers for Disease Control and Prevention (CDC). This number is likely an under-representation, as test results and epidemiologic information were not always available. The CDC review emphasizes the need for more education specifically related to aseptic technique in injection safety, review of practices and training, and implementation of a consistent oversight in preventing the transmission of bloodborne pathogens in healthcare settings.

Handoffs causing patient harm: A survey of medical and surgical house staff
By: Kitch BT, Cooper JB, Zapol WM, Marder JE, Karson A, Hutter M, Campbell EG.
BACKGROUND: Communication lapses at the time of patient handoffs are believed to be common, and yet the frequency with which patients are harmed as a result of problematic handoffs is unknown. Resident physicians were surveyed about their hand-off-practices and the frequency with which they perceive problems with handoffs lead to patient harm.
METHODS: A survey was conducted in 2006 of all resident physicians in internal medicine and general surgery at Massachusetts General Hospital (MGH) concerning the quality and effects of handoffs during their most recent inpatient rotations. Surveys were sent to 238 eligible residents; 161 responses were obtained (response rate, 67.6%).
RESULTS: Fifty-nine percent of residents reported that one or more patients had been harmed during their most recent clinical rotation because of problematic handoffs, and 12% reported that this harm had been major. Overall quality of handoffs was reported to be fair or poor by 31% of residents. A minority of residents (26%) reported that handoffs usually or always took place in a quiet setting, and 37% reported that one or more interruptions during the receipt of handoffs occurred either most of the time or always.
DISCUSSION: Although handoffs have long been recognized as potentially hazardous, further scrutiny of handoffs has followed recent reports that handoffs are often marked by missing, incomplete, or inaccurate information and are associated with adverse events. In this study, reports of harm to patients from problematic handoffs were common among residents in internal medicine and general surgery. Many best-practice recommendations for handoffs are not observed, although the extent to which improvement of these practices could reduce patient harm is not known. MGH has recently launched a handoff-safety educational program, along with other interventions designed to improve the safety and effectiveness of handoffs, for its house staff and clinical leadership.

Surgical Site Markers: Putting Your Mark on Patient Safety
Pennsylvania Patient Safety Authority
A surgical site mark should not be easily removed with skin preparation but should not be so permanent that it last weeks or months after the surgical procedure. The results of three studies were inconclusive in determining the best performance of marks on skin when used with skin prep solutions. Healthcare facilities may want to conduct their own studies of surgical site markers and/or skin prep solutions to determine performance.
MedSun has received reports describing similar issues with pre-surgical markers. To view these reports, see link under Addition Information below.

ISO Accreditation Comes to America: Are Labs Ready to Embrace an International Quality Management System?
By: Malone, Bill
American Association of Clinical Chemistry (AACC)
Clinical Laboratory News
The College of American Pathologists (CAP) recently rolled out an optional accreditation program based on the ISO 15189 standard for medical labs. The primary benefit of using ISO standards comes from following its comprehensive and highly structured approach for quality management, while also allowing labs to employ tools like Lean or Six Sigma. However, CMS is not ready to make ISO standards a required part of lab accreditation under CLIA.

Updated Guidelines for the Use of Nucleic Acid Amplification Tests in the Diagnosis of Tuberculosis
Centers for Disease Control and Prevention (CDC) MMWR Report
The CDC's updated recommendation says that nucleic acid amplification (NAA) testing should be performed on at least one respiratory specimen from each patient with signs and symptoms of pulmonary TB for whom a diagnosis of TB is being considered but has not yet been established, and for whom the test result would alter case management or TB control activities. However, culture remains the gold standard for laboratory confirmation of TB and is required for isolating bacteria for drug-susceptibility testing and genotyping.

Model #: REF 620-040-690
Lot #: 060308D
OR staff report that the insufflator blew apart where the device screws into the port at the machine side. The connection that goes into the insufflation machine itself literally blew apart with force. Staff report that this has happened several times in the recent past and that they have been reporting this and each event to the rep. Patient and staff were not harmed.
See picture of damaged insufflator.
Manufacturer: C.R. Bard
Model #: 153202
Bard Latex-Free 200ml urine meter with bag and Bard EZ-Lok Sampling Port, Ref#153202, and lot number unknown had to be changed by RN twice in twenty-four hours because the plastic piece that dumps urine from the tubing into the urometer kept breaking. This causes urine to go directly into the drainage bag without first flowing into the urometer. Urine outputs then becomes inaccurate for the hour. After talking with other RN's, we discovered that this had been happening frequently with other patients, requiring that they also have a foley system change. BioMed opened new Bard urine meter with lot number NGSK0339 and discovered the same issue. The bent plastic piece had gone into the meter twice, and it fell off of the drain tube easily as if it was not glued on at all.

During a scheduled Preventive Maintenance inspection, it was noticed that there was rust on the Rod of the Bag/Vent Switch assembly. The assembly was replaced with a new part.
Manufacturer response for Anesthesia Machines, Anesthesia Machines
GE acknowledges that there is a problem, and are in the process of sending us an official letter, after their analysis and investigation is complete. The presence of Chloride in their manufacturing process, either during machining or cutting is contaminating the parts causing them to rust. They initially were using stainless steel grade 303 and switched to stainless steel grade 313.

Harmonic Cord and open handpiece kept cutting off while cutting out the gallbladder. Handpiece and cord did not start doing this until after they cleaned the tip of the handpiece off. Kept giving Error code 5 "instrument". Changed handpiece and cord. It worked fine for a few minutes, then error code 5 and the code for handpiece temperature kept coming up.
Ethicon sales Representative tested the devices, along with the technical support people at Ethicon Endo-Surgery that were called on the phone. The actual same devices were used to perform this test, Problem could not be duplicated.
Ethicon was able to verify the errors stored in memory.
1- Error 1 is due to tissue stuck on the tip of the device.
2- Error 5 is a connection loose error between the handpiece single-use device and the cable.
3- The two cables were verified and checked, one had been used around 27 times and the other was used 15 times. Per manufacturer's guidelines, these cables should last well over 100 times.
The unit was returned back to service. The disposables will be shipped back to Ethicon Endo-Surgery Company, for further evaluation.

The vascular endo GIA stapler was inserted through one of the previous ports and placed across the superior segmental branch and fired. Upon removal of the stapler, the proximal staple line was noted to be incomplete and significant bleeding occurred. There was significant blood loss; however the procedure was completed without further complication. This patient did receive Hespan and 3 units of RBCs intraop. Patient was discharged home 10 days post op. The blood loss did not appear to impact the length of stay as patient had other some issues with a chest tube that had some increased drainage, but this resolved by discharge.

The patient was trying to move in the bed and lost her balance and slid out onto the floor. The nurse call alarm did not work and the patient was heard calling from the room. The patient had removed the non-skid socks earlier. RRT trauma and MD was called and no injuries were noted. The bed was checked by Biomed and this bed cannot be connected to the Hill-Rom nurse call system that is used on this floor, because of the type of communication cable connected to the bed. The bed was not connected to the nurse call system which would have alarmed through the nurse call system to notify the clinical staff that a fall had occurred. The bed and nurse call tested fine.

Stryker beds were found to have an unstable weld along the frame. There was no event with a patient. Twenty-one beds were examined and all have this unstable frame.
Manufacturer: B. Braun Medical, Inc.
Brand: Outlook 100
Model #: 13215
This report is a continuation of several reports previously filed. Our facility had been having ongoing issues with our B. Braun Outlook 100 pumps losing their drug libraries. This causes our RN's to resort to manual programming of rates, etc. We had reported a total of 379 events (there are a total 440 pumps total at our facility). We were initially told it was a battery problem by B. Braun. Then, we were told it was a software glitch. B. Braun came to our facility in mid-October to upgrade all of our pumps to a newer version of software. We were optimistic this upgrade had fixed the problem. Unfortunately, it was reported this morning that we have had 7 pumps lose their drug libraries so far this week. We will be creating a tool to keep track of how many times this happens, or if there are any repeat offenders, etc. There have been no impacts on patients at this time. The pumps were removed from service, and sent to our Clinical Engineering department for reloading of software. I did confirm that the 7 pumps had all received the recent software upgrade.
Manufacturer: Draeger Medical
Model #: Caleo
During the annual preventive maintenance procedure the Biomed Department discovered an issue with the manufacturer's procedure for calibrating the oxygen; it is not accurate and the unit does not respond in accordance with the manufacturer's documentation on the testing. We could not tell if the units passed the oxygen calibration or not. That made us uneasy so we went to their technical support for help. Until several discussions with technical support and the local service representative, Drager was not convinced there was an issue. Now that their service rep is involved they are finally convinced they may have a software issue with the oxygen calibration required by their software annually, and also in their service manual.
Device:Wound Care Mattress
Manufacturer: Kinetic Concepts, Inc.
Brand: 1st Step Select
Model #: 40525C
Reporter was informed in the morning that there had been a burn incident last week involving this unit, and to go check it out. Found that unit was still in use on patient. Warmer was in off position and filter was not clogged to cause over heating of unit. Hoses at unit outlet were luke-warm and routed back around to the unit.
Met with Risk Mgr. Incident involved hoses on top of the mattress overlay which touched patient’s foot and caused a 1st degree blister burn.
They are to do an internal Root cause investigation and hold meeting to report findings. Met with Root cause committee and found that staff incorrectly used equipment, reporting process was not correct, and suspected equipment was not removed. Discussed corrective actions and remedies for Policies and Procedures.
The Staff had incorrectly routed the hoses on top of the foot board instead of around the end and bottom of the foot board, thus causing the hoses to be able to come into contact with the patient’s foot.
Once I was notified, I pulled the unit and ran the unit the way it was set at that time. Found the temperature to be at 103 degrees.

Brand: Thioglycollate Vitamin KAnd Hemin
Lot #: 8164953
Other #: product # 221788
Gram stain results yielded gram positive beaded organisms on multiple specimens which were grounded using Thioglycollate. No organisms were seen when the same specimens were tested again without using Thioglycollate. The media was found to have high counts of nonviable organisms.
Manufacturer response for Microbiology Culture Media, Thioglycollate Vitamin K and Hemin
The response was that a Gram stain by itself can neither rule in or out infection since artifacts and non-viables may be present in the transport media. Most liquid media will have some level of microorganisms present in the product.
The batch history record was reviewed and was found to be satisfactory. There was no evidence of contamination in the retention sample. There was no evidence of contamination in the return sample.
Device:X-ray System, Cath/angio
Manufacturer: Siemens Medical Solutions USA, Inc.
Brand: Axiom Artis
Device:Information Management System, Cardiovascular
Manufacturer: McKesson Information Solutions LLC
Brand: Horizon Cardiology
Images from the Siemens Axiom Artis system are supposed to be archived automatically by the McKesson Horizon Cardiology Information system. Sometimes this does not happen. Departmental policy is that at the end of each case the monitoring tech is supposed to verify that the images have transferred over. Once the transfer and archiving is verified, the images can be deleted from the Siemens system.
In this case the team member noted that the images were missing, but didn't attempt to archive them. The team member then accidentally deleted the images from Siemens. Once deleted, these images can't be recovered. The cath procedure was re-done.
Device:Vascular Closure Device

As the physician was attempting to deploy the MYNX device, the balloon expanded but the physician was unable to withdraw the catheter to expose the sealant. After the MYNX was passed off the sterile field, the physician attempted to pull the catheter up, but was unable to do so. Blood loss during the procedure was within normal limits (50-100cc) and a total of 50 cc of radiopaque was used during the procedure. The patient did have a palpable popliteal pulse or the right side post procedure and was transported to recovery in stable condition. Physician stated one of every two MYNX devices used are defective.
Model #: P-2050
Early this morning, a blanket warmer overheated (it was set to run at 160F). The blankets inside started to smolder and Plant Operations was called because of the odor. Apparently there was not enough smoke to trigger a smoke alarm. They removed power and then removed the warmer to an outdoor location to minimize the odor in the area. A plant operation's technician opened the door and the blankets flashed into flames. They quickly put out the flames and the fire department was not notified. The investigation into the cause of the fire leads us to believe that the blanket warmer was overfilled, thereby blocking the unit’s temperature sensor.
In talking with the manufacturer, we were informed that a new base was available for the unit. The new base reduces the likelihood of blankets overheating because it allows for extra distance between the bottom of the cabinet and the heating element. The manufacturer also recommended no more than 90 blankets be placed in the unit, and that the blankets should be rotated. Loading blankets at the top and removing from the bottom. This would allow the top blankets more time to warm and keep blankets on the bottom from drying out.

Patient had 25-50% survivability prior to procedure due to extreme poor health. OR Procedure ECMO Insertion with cannulation by Cardiac Surgeon. Femoral graft attempted but there was severe bleeding (18 units in 1 hr at body of graft not anastomosis). A different graft was then placed in axillary artery with coagulopathy. Surgeon states used this graft for 2 years and that this one was defective. It is not clear what led to the massive bleeding but considering the amount of bleeding that occurred, there is legitimate suspicion that the weave might have been loose.

The patient was in the midst of a sestamibi treadmill stress test. During the test the patient had issues with frequent ectopy that were being closely monitored. When the patient got close to peak exercise, the monitoring system and treadmill froze, losing the ability to monitor this patient at a time when he was experiencing significant ectopy. Though the patient did not fall when the treadmill belt froze, we are concerned this could happen should this problem recur. We have had one prior occurrence of this problem in the past.
Device:X-ray Unit, Mini C-arm, Portable
Manufacturer: GE OEC Medical Systems
Brand: Mini View
Model #: 6800
Mini C-arm malfunctioned during a case; unable to shoot live films. Field Service Engineer replaced defective monitor. The monitor in this C-arm had also been replaced approximately one year earlier by the company. I talked to the GE Field Service Engineer briefly and he mentioned it seemed that those particular monitors were failing more often than he expected they should. He did not indicate that GE/OEC had a known problem with these monitors.
Device:X-ray Unit, C-arm, Portable
Manufacturer: Philips Medical Systems
Brand: Bv Pulsera
Model #: BV Pulsera
In the OR the C-arm would not work. No X-ray and display has message "M379 Battery overcharge has enabled itself". Display also says "reset" next to one of the buttons. Pressed reset, C-arm resets and now can make X-rays. Looked for error message in manual, unable to locate it. Spoke with Philips service rep - he was unable to find info on the message and said to ignore it if it doesn't come back. Rebooted unit and message came back.
In a follow-up message, Philips states "Error indicates monthly battery deep cycle is running or needs to run, should clear after reset. Ok to use C-arm". Checked C-arm the next morning, re-booted unit and still getting M379 error. Philips service was called in to resolve the issue. Found out that setting the date forward 2 months and rebooting the unit will clear the error. Although M379 error is a known issue, it rarely occurs. The unit can be safely used until the error is cleared.
Manufacturer: Varian Medical Systems, Inc.
Brand: Clinac Linear Accelerator 2100 Ex
Machine had been serviced several days before event. The physicist performed an IMRT (intensity modulated radiation therapy) quality assurance after service left. Quality assurance on the machine was not completed until he could review the plan the next day with the dosimetrist. After much consideration during the night, he called the next morning and requested that the dosimetrist monitor the first treatment of the day. The treatment was aborted on the first treatment field when MLC leaves did not move according to the patient's plan. Other treatments were simulated on the machine and nonstandard performance was again noted. The equipment was removed from service until vendor service was completed. Physicist performed checks on the machine and all IMRT/Forward Plans before resuming treatments. The machine was down two days.
Final response was not received from the manufacturer until several months later and it included the following information: The failure of a signal that communicates between the MLC and the Beam Gating PCB allowed the Beam to continue while the Step and Shoot field was changing from one field to another/broken or defective contact. In considering the worst case clinical scenario, it is assumed that only one field would receive treatment in this manner before a clinical user would notice that a beam hold is not asserted when the MLC leaves are moving. Step and Shoot treatments are typically the only type dynamic modality delivered at a site, and clinical users are accustomed to hearing the change of the audible beam tone from on to off when the beam hold is asserted: the failure of this change in tone would be apparent. Severity Rationale: Portions of critical structures may receive some dose while the expectation is that the beam has been held (turned off temporarily) to prevent dose from being delivered to critical structures. The planned dose targets would receive slightly lower dose, equal to the dose that had been incorrectly delivered during the prior step segment that should have been delivered during the shoot segment. Probability of harm rationale: the user can hear the Beam On Tone relevant to radiation being gated on and off. The presence and absence of the Beam On tone during high repetition rates is highly detectable. All users, typically a team, would have to not notice this situation. It will be obvious to those monitoring the treatment to notice the beam control was not working correctly due to their familiarity of this treatment type.

Brand: Immulite 2000
Model #: Immulite 2000
After being notified by an Endocrinologist that one of their patients had "unusual" results for Free T4 and TSH, we repeated the tests on the original sample in question the next day and found that the originally reported results were incorrect. The physician was notified of the corrected results. During further investigation we found nothing unusual about the samples. There were no related error messages on the Immulite 2000 instrument and no noticeable differences with anything at the time of repeating the tests. The instrument manufacturer's technical support was called the same day, but no immediate cause for the error was found. Technical support downloaded information from our instrument and told us that they would look into the matter. Two days later the technical service engineer relayed to the physician that there were numerous error messages contained in a log file that we should have been alerted to but were not. The engineer also found several parts that needed to be replaced and could have produced the erroneous results. These parts were replaced and additional quality control checks were performed. We are aware of only one patient that had unnecessary follow-up procedures started due to initial incorrect results.

Lot #: 2424625
Patient admitted for revision right total hip replacement due to failed acetabular component. Indications: Patient clinical evidence for persisting weight bearing pain, right hip consistent with acetabular component loosening. Preoperative x-rays were satisfactory. Clinical experience indicated a strong suspicion of a microscopically loose acetabular component. There was no evidence of infection preoperatively. Findings: Consistent with microscopic loosening of a Durom 50-mm acetabular component metal on metal construct with a 44-mm inner diameter and a corresponding 44-mm diameter metallic head. No evidence of infection. Intraoperative gram stain negative for organisms or significant white cell count. She had a Durom system implant for treatment of osteoarthritis of her right hip. Her hip "never really got better." It became noticeably worse 2 months following surgery. She was having continued discomfort particularly navigating stairs. Eight weeks after surgery, she was still using crutches. X-rays at that time showed no change in the position of the construct including the cup. There were no loosenings noted.

Over the past 2 years, MedSun has received 12 adverse event reports associated with the Mayfield Skull Clamp device manufactured by Integra LifeSciences Corporation. A neurosurgical head holder (skull clamp) is a device used to clamp the patient's skull to hold the head and neck in a particular position during surgical procedures. The reports were submitted by 6 hospitals between February 13, 2007 and February 13, 2009. The most frequently reported device problem was:
• Unintended movement or slippage of the skull clamp or pins
None of the reports involved a patient death. The patient injuries listed below were reported in 9 of these 12 reports.
All 9 of the reports that listed patient age had a patient age listed as greater than 21 years. Of the reports that listed patient gender, a total of 8 reports involved female patients and a total of 4 reports involved male patients.
These MedSun reports contributed to FDA awareness of the device problems. FDA currently has this issue under review.
|Device||Device Identifiers||Event Description|
|Integra LifeSciences Corp. / MAYFIELD Headrest||Device identifiers unknown||Patient was placed on a Mayfield Headrest while on a stretcher. Patient was flipped onto OR bed and connected to the base of the Mayfield Headrest. Once connected it would not stay locked onto the patient's head, and the patient suffered two 4-6 inch lacerations to scalp. Large amount of blood poured onto floor and patient then had to be flipped back onto stretcher. Wounds were sutured.|
|Integra LifeSciences Corp. / MAYFIELD Modified Skull Clamp with Skull Pins||Device identifiers unknown||During the prep stage, the patient was placed in Mayfield head holder by the neurosurgical resident. Left sided pin was tightened to a torque of 60 lbs. Patient was being positioned by the resident and the physician assistant, the pin slipped and a 1.5 cm laceration of the scalp resulted on the left temporal region. The resident sutured the laceration, and notifications were sent out. C-clamp and pins for the Mayfield were replaced with another set. The c-clamp and pins were segregated. This was a loaner set in which the torque screws were located on the two pin holders as well as on the left side of the c-clamp. The neurological Director requested an extra staff member be available at the head of the table with the Anesthesiologist to prevent this event from recurring.|
|Integra LifeSciences Corp. / MAYFIELD Head Clamp||Device identifiers unknown||Partway through a laminectomy procedure, while holding the hand drill to make entrance holes for screws in posterior cervical spine, there was a "clunk" and the head/neck very obviously changed position. Shortly after, Anesthesia informed of new and significant blood loss from area of pins. Surgeon found large laceration at original pin site (single pin site) going through to skull and periosteum was removed. Another laceration, slightly less deep, was perpendicular to this. Lacerations were cleaned and sutured. Pin not found in original position and fully retracted. (Of note, this was a loaner clamp following the recent problem with our own Mayfield skull clamp.)|
|Integra LifeSciences Corp. / MAYFIELD||A-1059||Head clamp holds three skull pins for stabilizing the head during neurosurgical procedures. On turning patient to prone position, one pin slipped and cut the patient's skin. The clamp was reapplied in different area of skull and patient was connected to bed attachment for securing patient head in proper position for surgery.|
|Integra LifeSciences Corp. / MAYFIELD||40A1059||Skull clamp placed by a resident intra-operatively caused a laceration of the skull.|
|Integra LifeSciences Corp. / MAYFIELD Skull Clamp||A-1059|| Surgeon placed skull clamp on patient's head. Patient then turned prone in preparation for surgery on cervical spine. Clamp was firmly attached to Mayfield base support which is firmly attached to the OR table. While head was being repositioned by surgeon the swivel lock appeared to become unlocked and patient's head fell downward with the bridge of his nose striking the crossbar of the skull clamp. This injury was superficial. The surgeon once again repositioned and re-secured the head but then the head was "spontaneously ejected" from the skull clamp, resulting in a deep 5cm laceration above the right ear. This required closure with skin staples.|
Manufacturer response for Skull clamp/head support (per reporting facility):
The manufacturer acknowledged the device's inherent instability. They supplied us with a loaner clamp while they evaluate ours. They provided me with the instructions for use upon request. The IFU does state that "The direction of the single pin should point directly through the center point created by the centerlines of the patient's head with the pins on the two-pin side of the skull clamp being equidistant to single-pin line of direction to obtain the highest degree of stability."
|Integra LifeSciences Corp. / MAYFIELD||Models 1059 and A1072|| A three cm laceration was noted on the patient’s left side of the scalp as the patient was being positioned for posterior cervical laminectomy. The Mayfield skull clamp (Integra 1059) was being applied by the Doctor with Mayfield disposable skull pins in place (Integra A1072). Packaging was discarded; lot #, expiration date unknown. |
Laceration closed. New skull pins applied. Another Mayfield Skull Clamp used without incident. Original Mayfield Skull Clamp removed from the OR, to be sent to company for evaluation with the permission of Risk Management.
|Integra LifeSciences Corp. / MAYFIELD||40A1059|| The patient was scheduled for posterior cervical fusion.|
At the end of the procedure, it was noted that the pin sites on the head had shifted. The left posterior pin site had a one inch tear. The laceration was sutured by the surgeon.
|Integra LifeSciences Corp. / MAYFIELD||Device identifiers unknown||The patient was being positioned on OR table for anterior cervical fusion with horseshoe head holder. Surgeon felt that head holder moved as pressure was being applied. Circulating nursing did not observe any movement. No patient harm per surgeon. Device sent to manufacturer for evaluation.|
|Integra LifeSciences Corp. / MAYFIELD||A-1059||Case was a craniotomy. Intraoperatively after application of Mayfield skull clamp it slipped out of position from the patient's head. Patient not injured and the appliance was replaced with another Mayfield skull clamp.|
|Integra LifeSciences Corp. / Integra MAYFIELD Skull Clamp||40A1059||After application of the head holder, it slipped twice causing two lacerations. The lacerations were stapled.|
|Integra LifeSciences Corp. /Mayfield Head Rest or Head Clamp||A-1059||Patient was undergoing AVM for Chiari Malformation when intraoperatively the resident heard and then saw pins on Mayfield pop out of patient's head. Resident secured head and new Mayfield head rest was brought to OR. The new Mayfield was positioned, patient assessed and the new Mayfield remained in place for remainder of surgery. Outcome is still open to sequelae due to intraoperative surgery halt.|

Clinical Engineering was called by the OR and informed that the return plate of the disposable shears had been damaged during the case. There wasn't any harm, but they wanted the device checked to make sure it is working properly. The salesman took the damaged disposable. He retrieved all 4 hand controllers because there wasn't any indication as to which was used. Completed safety and functional tests of the generator as per manufacturer's specifications. Completed functional test on hand controllers. Phase Margin (Hz)range should be between 170-247. Impedance (Zr) range should be between 15 - 40. No issues identified. All hand controllers were operating within tolerance. Clinical Engineering called the Ethicon sales rep. He explained that the incident was caused by the hand controller being activated after the shears had cut through tissue causing both sides to touch. If this happens throughout the case it could have caused damage to the return plate.
