“…To avoid making an error such as different tidal ventilation at each measurement, T0 was measured while mechanical mask ventilation to maintain the tidal volume as 8 mL/kg of ideal body weight with a respiratory rate of 12 times/min and the other measurements were taken under mechanical ventilation whose tidal volume was set 8 mL/kg of ideal body weight without positive end expiratory pressure. With the probe fixed on the right midaxillary line at approximately between the sixth to ninth intercostal spaces, the ultrasound beam was directed to the hemidiaphragmatic domes at an angle of about 70 degrees [10, 11]. The liver was used as the marker of window for the right hemidiaphragm (Fig 1).…”

Major laparoscopic pelvic surgery requires steep Trendelenburg position with pneumoperitoneum for a long time. We investigated the effect of Trendelenburg position with pneumoperitoneum on diaphragmatic excursion and lung compliance during major laparoscopic pelvic surgery using M-mode sonography. Twenty patients undergoing elective pelviscopic radical hysterectomy were included in this study. Diaphragmatic excursion was measured at the following time points; after sedation, after intubation, 90 minutes after Trendelenburg position with pneumoperitoneum, and after operation with recovery of muscle relaxation. And lung compliance was measured using anesthetic machine under general anesthesia; after the intubation, 90 minutes after Trendelenburg position with pneumoperitoneum and after operation with recovery of muscle relaxation. In order to detect postoperative pulmonary complication, postoperative chest radiography was checked. Static lung compliance, dynamic lung compliance and diaphragmatic excursion were decreased during operation (P < 0.001, respectively). At the end of the operation with recovery of muscle relaxation, reduced diaphragmatic movement was not recovered as its excursion after sedation (P < 0.001). In conclusion, lung compliance was decreased following transiently decreased diaphragmatic excursion during major laparoscopic pelvic surgery.
