Summary
A patient experienced cardiac arrest after laparoscopic surgery due to venous gas embolism, a rare complication. Prompt recognition of subtle cardiorespiratory signs is crucial for early detection and intervention.
Area of Science:
- Anesthesiology
- Cardiovascular Surgery
- Critical Care Medicine
Background:
- Laparoscopic cholecystectomy is a common procedure.
- Patients with arterial hypertension may have underlying cardiovascular risks.
Observation:
- A 50-year-old woman developed cardiac arrest 6 hours post-laparoscopic cholecystectomy.
- Preceding symptoms included dyspnea, asthenia, and anxiety.
- Intraoperative hypotension without respiratory changes was noted.
Findings:
- Myocardial infarction, aortic aneurysm, and pulmonary embolism were ruled out.
- Elevated right ventricular outflow resistance and transient coagulation abnormalities suggested venous gas embolism.
- The patient developed persistent cortical blindness post-event.
Implications:
- Venous gas embolism is a potential complication of laparoscopic surgery.
- Anesthetists must monitor for subtle cardiorespiratory instability postoperatively.
- Vigilance and increased monitoring are essential for early detection and management.
