The objective of this study was to determine the effects of low-pressure intra-abdominal application on laparoscopic cholecystectomy on acid-base equilibrium. Thirty patients were included in this study. Group 1 patients had 8 mmHg intra-abdominal pressure and Group 2 had 12 mmHg intra-abdominal pressure when they were operated on. There were no significant differences between the groups in terms of their age, sex, body mass index, insufflation and operation time, and anesthesia duration. The acid-base equilibrium situations were similar. Short-term metabolic, respiratory, and mix-type acidosis was observed during the operation and becomes normal in the recovery room. Acidosis is more likely related to the absorption of CO2 in the peritoneum rather than to secondary changes caused by intra-abdominal pressure increases. No positive effects of the application of intra-abdominal low pressure on laparoscopic cholecystectomy on acid-base equilibrium were observed in our study.
本研究的目的是确定腹腔镜胆囊切除术中低压腹腔内应用对酸碱平衡的影响。本研究纳入了30例患者。第1组患者在手术时腹腔内压力为8 mmHg，第2组为12 mmHg。两组在年龄、性别、体重指数、气腹时间、手术时间和麻醉持续时间方面无显著差异。酸碱平衡情况相似。手术期间观察到短期代谢性、呼吸性和混合型酸中毒，在恢复室恢复正常。酸中毒更可能与腹膜中二氧化碳的吸收有关，而非腹腔内压力升高引起的继发性变化。在我们的研究中，未观察到腹腔内低压应用于腹腔镜胆囊切除术对酸碱平衡有积极影响。
