背景：本研究旨在评估腰麻下足月产妇测量腹内压的可行性。方法：对20例腰麻择期剖宫产术后足月产妇进行腹内压测定。在仰卧位和100个左侧倾斜位置测量压力，并始终保持恒定的参考点。结果：腹内压测量方法可行、安全。左侧侧卧位的血压明显低于仰卧位（10.9 mmHg +/- 4.67 vs 8.9 mmHg +/- 4.87, P = 0.0004）。妊娠期腹内压的范围很宽，从2到20 mmHg， > - 25%的患者在两种体位下休息时压力都高于12 mmHg。结论：在脊髓麻醉下，25%的健康足月产妇腹腔内压为> 12mmhg，传统上定义为腹腔内高压。足月妊娠时应采用左侧侧卧位测量腹内压，以免测得的压力过高。(C) 2011 Elsevier Ltd.版权所有。
Background: This study was conducted to assess the feasibility of measuring intra-abdominal pressure in term parturients under spinal anesthesia.Methods: Intra-abdominal pressure was measured in 20 term parturients after spinal anesthesia for elective caesarean section. Pressure was measured in the supine and 100 left lateral tilt positions with a constant reference point throughout.Results: Intra-abdominal pressure measurement was feasible and safe to perform. Pressure was significantly lower in the left lateral tilt position than supine (10.9 mmHg +/- 4.67 vs. 8.9 mmHg +/- 4.87, P = 0.0004). The range of intra-abdominal pressure in pregnancy was wide, from 2 to 20 mmHg, with >25% of patients resting with pressures above 12 mmHg in both positions.Conclusions: Under spinal anesthesia, intra-abdominal pressure in >25% of healthy term parturients was > 12 mmHg, which has conventionally been defined as intra-abdominal hypertension. The intra-abdominal pressure in term pregnancy should be performed in the left lateral tilt position to avoid falsely elevated pressure measurements. (C) 2011 Elsevier Ltd. All rights reserved.
