Changes of median hepatic venous blood flow (MHVBF) and left portal venous blood flow (Lt. PVBF) were measured continuously in 31 patients undergoing elective laparoscopic cholecystectomy (LC) by using transesophageal echocardiography (TEE). The patients were anesthetized with inhalation and epidural anesthesia. MHVBF and Lt. PVBF decreased from preoperative level of 317 +/- 61 ml.min-1, 522 +/- 86 ml.min-1 to 73 +/- 22 ml.min-1, 98 +/- 28 ml.min-1 after inflation with high pneumoperitoneum pressure and they recovered by deflation. These findings suggest that hepatic blood flow decreases by increased intraperitoneal pressure.
采用经食管超声心动图（TEE）对31例行择期腹腔镜胆囊切除术（LC）的患者，连续测量肝中静脉血流（MHVBF）和左门静脉血流（Lt. PVBF）。患者采用吸入麻醉和硬膜外麻醉。高气腹压力充气后，MHVBF和Lt. PVBF从术前的317±61 ml·min⁻¹、522±86 ml·min⁻¹降至73±22 ml·min⁻¹、98±28 ml·min⁻¹，放气后恢复。这些发现提示肝血流因腹腔内压力升高而减少。
