To investigate the influence of increased intra-abdominal pressure during pneumoperitoneum on splanchnic circulation.
Open study.
University hospital, Sweden.
Five otherwise healthy patients (mean age of 34 years), undergoing laparoscopic cholecystectomy.
Arterial and hepatic vein catheterization and simultaneous arterial and hepatic vein blood gas sampling in the awake state, during anaesthesia, after the establishment of pneumoperitoneum (intra-abdominal pressure level 11-13 mmHg) and after 30 and 60 minutes of pneumoperitoneum.
Hepatic blood flow was estimated by the continuous infusion method and used as a measure of splanchnic blood flow. Splanchnic oxygen consumption was calculated according to the Fick principle.
Splanchnic blood flow and splanchnic oxygen consumption were not affected by pneumoperitoneum at this level of intra-abdominal pressure.
探讨气腹期间腹腔内压力升高对内脏循环的影响。
开放性研究。
瑞典大学医院。
五名其他方面健康的患者（平均年龄34岁），接受腹腔镜胆囊切除术。
在清醒状态、麻醉期间、气腹建立后（腹腔内压力水平为11 - 13 mmHg）以及气腹30分钟和60分钟后进行动脉和肝静脉插管，并同时采集动脉和肝静脉血气样本。
采用连续输注法估算肝血流量，并将其作为内脏血流量的指标。根据菲克原理计算内脏氧耗量。
在该腹腔内压力水平下，气腹未影响内脏血流量和内脏氧耗量。
