Alterations in respiratory function and hemodynamics during laparoscopic cholecystectomy under pneumoperitoneum
Surgical Endoscopy
|November 1, 1993
Summary
Laparoscopic cholecystectomy (LC) with 10 mmHg pneumoperitoneum (PP) caused respiratory changes but no critical cardiac issues. Renal blood flow may decrease in some patients during LC, even at lower intra-abdominal pressures.
Area of Science:
- Anesthesiology
- Surgical Innovation
- Cardiopulmonary Physiology
Background:
- Laparoscopic cholecystectomy (LC) utilizes carbon dioxide insufflation for pneumoperitoneum (PP).
- Understanding the physiological effects of PP on respiratory and hemodynamic function is crucial for patient safety.
Purpose of the Study:
- To evaluate respiratory function, hemodynamics, and renal function during LC under 10 mmHg PP.
- To assess the safety and impact of this surgical approach on vital organ systems.
Main Methods:
- Blood-gas analysis and Swan-Ganz catheterization were used to monitor respiratory and cardiac function.
- Creatinine clearance rate (Ccr) was measured preoperatively and intraoperatively.
Main Results:
- Significant increases in PCO2 and decreases in pH and base excess were observed during PP.
- No significant changes in cardiac output or pulmonary pressures were detected.
- Intraoperative Ccr showed no overall significant difference, but decreased significantly in 8 individual cases.
Conclusions:
- LC at 10 mmHg PP causes manageable respiratory alterations without critical cardiac compromise.
- Clinicians should be aware of potential decreases in renal blood flow, even at moderate intra-abdominal pressures.
