Cardiovascular collapse during laparoscopy: a report of two cases

Area of Science:

• Minimally invasive surgery
• Cardiovascular complications
• Anesthesiology

Background:

• Laparoscopic procedures are common surgical techniques.
• Cardiovascular collapse is a rare but potentially fatal complication during laparoscopy.
• Understanding the causes is crucial for patient safety.

Observation:

• Two cases of sudden cardiovascular collapse during laparoscopic surgery are presented.
• Patients experienced abrupt hemodynamic instability.
• The collapses occurred without clear preceding events.

Findings:

• Severe atypical vagal reactions were considered a primary cause.
• Carbon dioxide embolism was identified as another potential cause.
• Arterial blood gas analysis revealed significant pulmonary vascular shunting.

Implications:

• Highlights the importance of recognizing and managing rare cardiovascular complications in laparoscopy.
• Suggests vigilance for vagal responses and CO2 embolism during laparoscopic procedures.
• Emphasizes the utility of arterial blood gases in diagnosing intraoperative shunting.
