The zoll catheter in complaint will not be returned for investigation.Therefore, a physical investigation will not be performed.A supplemental report will be filed if the product is returned and investigation has been completed.It should be noted that some proposed explanations of death provided by physician are massive pulmonary embolism (pe), spinal shock and magnesium overdose.Thus death was probably related to the patient's clinical condition and not related to ivtm catheter or procedure.
