Summary
Postoperative pulmonary atelectasis, termed gravity-dependent atelectasis (GDA), occurred in two patients after laparoscopic nephrectomy. This case report details GDA
Area of Science:
- Anesthesiology
- Thoracic Surgery
- Surgical Complications
Background:
- Laparoscopic nephrectomy in the lateral kidney position is a common surgical procedure.
- Prolonged duration in the lateral kidney position can predispose patients to respiratory complications.
- Pulmonary atelectasis is a known risk, but gravity-dependent atelectasis (GDA) specifically requires attention.
Observation:
- Two patients undergoing laparoscopic nephrectomy in the lateral kidney position developed pulmonary atelectasis.
- Both patients were intubated with a single lumen endotracheal tube.
- The lateral kidney position was maintained for over 9 hours in both cases.
Findings:
- Atelectasis predominantly affected the lower lung zones, consistent with gravity-dependent atelectasis (GDA).
- The single lumen tube and prolonged lateral position likely contributed to the GDA.
- The report identifies GDA as a specific complication in this surgical context.
Implications:
- Awareness of GDA is crucial for surgeons and anesthesiologists performing prolonged laparoscopic procedures in the lateral position.
- Prophylactic measures and prompt treatment strategies for GDA should be considered.
- Further research into optimizing patient positioning and ventilation strategies may mitigate this risk.
