What is the initial management step for suspected gas embolus during laparoscopy?

• A. Cessation of insufflation
• B. Increase pneumoperitoneum pressure to tamponade
• C. Immediate CPR
• D. Administer high-dose diuretics

Answer: (A)

Gas embolism during laparoscopy occurs when CO2 under pressure enters torn veins and travels to the heart and lungs. The first priority is to stop any further gas from entering the circulation, so the immediate action is to cease insufflation. This halts ongoing embolization and stabilizes the patient by removing the continuing source of gas. After stopping insufflation, the focus shifts to supportive measures: administer 100% oxygen, position the patient in a left lateral decubitus and slight head-down (Durant-like) position to help trap gas in the right atrium and improve venous return, and attempt to aspirate gas if a central venous catheter is in place. Monitor hemodynamics and provide resuscitation as needed. Increasing pneumoperitoneum pressure would worsen the embolism, and immediate CPR or high-dose diuretics are not appropriate as first steps unless cardiac arrest or fluid overload is occurring, respectively.
