This randomized controlled trial evaluated the impact of alveolar recruitment maneuver (RM) on intraoperative hemodynamics in 70 patients undergoing laparoscopic hysterectomy. The study found that RM significantly improved mean arterial pressure, cardiac index, stroke volume index, dynamic lung compliance, and oxygenation parameters without causing clinically significant hemodynamic instability.
Key findings
- Mean arterial pressure, cardiac index, and stroke volume index were significantly higher in the RM group.
- Dynamic lung compliance, PaO2, and PaO2/FiO2 ratios were significantly improved with RM.
- Stroke volume variation and pulse pressure variation were significantly lower in the RM group.
Why it matters
Understanding the effects of alveolar recruitment maneuvers on hemodynamics and lung function can help clinicians optimize intraoperative management during laparoscopic procedures, potentially improving patient outcomes related to oxygenation and lung mechanics.
