Carbon dioxide gas embolism during robot-assisted laparoscopic partial nephrectomy

Area of Science:

• Urology
• Surgical Technology
• Anesthesiology

Background:

• Laparoscopic surgery, particularly robot-assisted partial nephrectomy, is increasingly common.
• Gas embolism, specifically carbon dioxide embolism, is a known but rare complication with high mortality.
• Maintaining optimal intra-abdominal pressure is crucial for patient safety during these procedures.

Observation:

• A case of carbon dioxide gas embolism occurred during robot-assisted laparoscopic partial nephrectomy in a 77-year-old woman.
• Sudden decreases in end-tidal carbon dioxide and peripheral oxygen saturation were noted shortly after tumor resection.
• Pulmonary artery gas embolism was diagnosed, prompting immediate intervention.

Findings:

• Lowering pneumoperitoneum pressure and restarting positive end-expiratory pressure led to patient stabilization.
• The patient's condition improved, allowing for the successful completion of the partial nephrectomy.
• This event highlights the critical nature of monitoring and managing gas embolism during robotic surgery.

Implications:

• Carbon dioxide gas embolism during robot-assisted partial nephrectomy requires heightened awareness and prompt diagnostic capabilities.
• Individualized adjustment of pneumoperitoneum pressure, rather than a uniform approach, may be necessary to mitigate risks.
• This case underscores the importance of timely intervention in improving survival rates for rare surgical complications.
