Massive Carbon Dioxide Embolism During Laparoscopic Liver Resection: A Case Report

Area of Science:

• Minimally invasive surgery
• Anesthesiology
• Surgical complications

Background:

• Carbon dioxide embolism (CO2E) is a rare but life-threatening complication during laparoscopic surgery.
• The incidence of CO2E during laparoscopic procedures is low, approximately 0.15%.
• Limited documented evidence exists on the specific effects of massive CO2E during laparoscopic liver resection on critical physiological parameters.

Observation:

• A case of massive CO2 embolism during laparoscopic liver resection is presented.
• The embolism was suspected due to hemodynamic instability and elevated end-tidal CO2 (EtCO2).
• Arterial blood gas analysis confirmed the diagnosis of CO2 embolism.

Findings:

• The patient experienced significant cardiovascular, respiratory, and encephalographic changes due to the massive CO2 embolism.
• Rapid surgical closure of the vascular breach led to immediate improvement in the patient's vital signs.
• No further adverse consequences were observed post-intervention.

Implications:

• This case highlights the critical cardiovascular, respiratory, and encephalographic effects of massive CO2 embolism.
• Emphasizes the necessity of close collaboration between surgeons and anesthesiologists during laparoscopic procedures.
• Underscores the importance of prompt diagnosis and immediate treatment for CO2 embolism to ensure patient safety.
