Pulmonary edema following laparoscopic bariatric surgery

Area of Science:

• Anesthesiology
• Bariatric Surgery
• Pulmonary Medicine

Background:

• Laparoscopic bariatric surgery presents unique perioperative challenges in obese patients due to increased intra-abdominal pressure and physiological changes.
• These factors can exacerbate pulmonary complications, necessitating careful anesthetic management and monitoring.

Observation:

• A 23-year-old morbidly obese female patient developed acute pulmonary edema post-laparoscopic adjustable gastric banding.
• Intraoperative records indicated approximately 5 minutes of unintentional one-lung ventilation during the procedure.

Findings:

• Postoperatively, the patient presented with profuse pink frothy sputum from the left lung.
• Chest roentgenogram revealed left lung atelectasis and severe edema, superimposed on diffuse bilateral interstitial pulmonary edema.

Implications:

• This case highlights the critical risk of pulmonary edema following laparoscopic bariatric surgery, especially with inadvertent one-lung ventilation.
• Prompt recognition, airway management, and supportive care are crucial for favorable outcomes in such patients.
• Enhanced vigilance during laparoscopic procedures in obese patients is essential to prevent severe perioperative pulmonary complications.
