Correlation between intra-abdominal and intra-plural pressure in patients with positive pressure ventilation
摘要
Abstract
Objective To assess the correlation of intra-abdominal pressure(IAP) with intra-pleural pressure (IPP) in patients under anesthesia and muscle relaxant condition with different positive end-expiratory pressure(PEEP). Methods In 20 mechanically ventilated patients who were anesthetic and muscle relaxed with closed drainage and catheter. Abdominal pressure were measured with indirect method and intrapleural pressure were measured with direct method at a sequentially increasing PEEP (0, 5, 10 and 15 cmH2O). Results The IAP was 8. 15 ± 3. 46 mmHg at PEEP 0 (zero end-expiratory pressure, ZEEP), 8. 31 ± 3. 66 mmHg at PEEP 5,9. 92 ± 3. 75 mmHg at PEEP 10 and 12.46 ±5. 55 mmHg at PEEP 15 (P < 0. 05 vs ZEEP). The IPP was 9. 31 ± 5. 72 mmHg at PEEP 0 (ZEEP), 9.15 ±5.93 mmHg, at PEEP 5,12. 23 ±6. 29 mmHg at PEEP 10 and 16.23 ±5.99 mmHgat PEEP 15. The intra-abdominal pressure was closely correlated with intrapleural pressure at different PEEP with a Pearson correlation coefficient R2 = 0. 789 (p < 0. 01). Conclusion Intra-abdominal pressure has close correlation with intra-pleural pressure in patients under anesthesia and muscle relaxation condition with different PEEP.关键词
