Patient Problems Burn(s) (1757); Full thickness (Third Degree) Burn (2696)

Event Type  Injury  

Event Description

It was reported that a patient received burns during a surgical procedure using the iled 7 surgical light system.Specific details of the alleged burn were not reported.Multiple attempts to obtain additional details of the event, classification of the burn, characteristics of the burn, and medical treatment provided were unsuccessful.This report was filed in our complaint handling system as complaint #(b)(4).

Manufacturer Narrative

Inspection of the device is pending.Further investigation should confirm the root cause.Investigation results will be provided within a final report if new information will become available.

Event Description

It was initially reported that a patient sustained a burn during a surgical procedure using the iled 7 surgical light system.Additional details received described the burn as "blisters to the left groin distal to the surgical incision." the area was noted to measure 8.18 cm² and was treated with an ¿absorbent dressing to keep the wound moist.¿ no additional intervention was reported.Per the information provided, the burn shows a large red area containing the characteristics of a ruptured blister, indicative of a partial-thickness second to third-degree burn.Based on the information provided by the customer, the injury appears to be a serious injury and would typically require medical intervention to preclude permanent impairment.This report was filed in our complaint handling system as complaint #(b)(4).

Manufacturer Narrative

The causality of the burn is unable to be determined at this time as the investigation is ongoing, additionally, an inspection of the device performed by a baxter representative is pending, therefore the functionality of the device cannot be determined at this time.If any additional relevant details are received the complaint will be addressed accordingly.

Manufacturer Narrative

Based on the provided information by the customer (initial user report, follow-up information, on-site visit, video call) it was determined that several light fields with high intensity were overlapped by the user.Overlapping light fields with high intensity may cause burns in the wound area or skin.This residual risk is described within the instructions for use.An on-site investigation was conducted, and two light heads were exchanged from the customer location to perform a deeper device investigation at our facility.A second visit at the affected customer location was done in week 3 of 2024.The team consists of functions from technical service, r&d, quality assurance, medical affairs, medical device vigilance and our distributor.Interviews and discussions were held with the staff of the surgical rooms to obtain more information on the use of surgical lights, staff training and knowledge of general risks associated with surgical lights.Additionally, more iled 7 lights in several operating rooms were inspected and data gathered for further investigation.Conversations with the biomedical engineers about their findings and investigations on the lights were also done.As a result the root cause was traced to overlapping of several light fields with high intensity.The iled 7 surgical light was designed according to iec 60601-2-41 2009/a1:2013 and meets these requirements.The iec also indicates that overlapping of more than one light field (luminaires) can exceed the irradiance of 1000 w/m².Therefore, information shall be given with the instructions for use (ifu) that there is a risk of too much heat in the operating field.The iled 7 ifu includes a warning for this risk as well as for other conditions where it is possible to increase the irradiance.The 1000 w/m² are the limits for potential undesirable temperature rise in the operating field per the iec.The iled 7 produces 623 w/m² for the single light head.In case of overlapping with high intensity the 1000 w/m² may be exceeded.From the overall investigation some other findings were available.Not at all light heads the calibration values were available which ensures the correct distance measuring and following the correct light setting.This may lead to higher values but this was evaluated to not contribute to skin burns as a solely cause.Additionally, in case the light head is moved very slowly and carefully, the motion sensor does not recognize a movement of the light head.Following this, the light head will not trigger a new distance measurement.This led to higher values which may contribute to skin burns.This behavior was determined to be not a use case.It was only reproduceable when moving the light head with two hands very slowly and sensitive up or down.In the normal surgical environment the light head will be moved with one hand on the center handle or with one hand at the housing.Doing this, it could not be reproduced that the sensor will not recognize a movement.Based on the root cause investigation the instructions for use (ifu) will be updated to include further advise and guidance on led overhead light handling/usage.Additionally, the remaining risk will be described in more detail.A fsca will be initiated to provide each user/customer this updated ifu as well as awareness of the potential risk.Further, it will be evaluated which technical update can be provided to customers to reduce the risk further.This evaluation is currently ongoing but will also be considered within the fsca execution.
