● Intraoperative deaths can occur both in emergency (e.g., treating a gunshot wound/GSW to the chest) or non-emergency (e.g., open heart valvoplasty) surgical situations
● In general, the surgical procedure (e.g., specific organ operated on or type of instruments used); type of anesthesia (local or general) or contrast dye (i.e., iodine) all have risks that could lead to unexpected sudden death
● Non-emergency or elective surgical procedures require a signed informed consent from the patient stating the risks involved; if not, the consent may be signed by the next-of-kin or power-of-attorney
● Recently, there has been a significant drop in intraoperative deaths due to the routine use of surgical and anesthesiology safety check lists to avoid potential errors
● Multiple factors can increase the risk of intraoperative deaths, such as age, person's state of health, co-morbidities, genetic factors, tobacco use, alcoholism, history of illicit drug abuse, past medical noncompliance issues, etc.
● Deaths from improper intubation during a medical/surgical emergency does not necessary mean that the person performing the procedure was incompetent
Causes of death
● Generally, in decreasing order, most intra-operative deaths are due to:
Complications from the disease itself, such as:
● ARDS during a bariatric gastric bypass procedure
● Air embolism to the heart during thoracic surgery
● Malignant hyperthermia from general anesthesia
● Ischemic stroke during IVC filter placement
● Manner of death is usually "Natural"
Human error that occurs outside the standard level of medical/surgical practice (a.k.a. medical malpractice), such as:
● Perforating the heart using the wrong surgical instrument
● Wrong dose of intraoperative anesthesia
● Manner of death is usually "Accident"
Death from undetermined cause(s)
● All possible causes of death have been ruled out
● Despite no surgical/anesthesiology errors occurring, patients may still die intraoperatively
● Deaths that occur immediately after surgical procedure (hours) or during immediate post-operative (days/weeks) hospitalization
Causes of death
Natural cause of death:
● Intracranial surgery: sepsis, hemorrhage
● Thoracic surgery: ARDS, pneumonia, acute myocardial infarction/arrhythmia
● Intra-abdominal surgery: peritonitis/sepsis
Accidental cause of death:
● Given wrong dose of medication
● Given wrong medication
