We measured how much CO gas was used in urologic laparoscopic surgeries and studied whether the amount of gas was associated with postoperative pain.
Four hundred sixty-three patients underwent urologic laparoscopic surgeries by a single surgeon. All surgeries were performed by a transperitoneal approach under a 15-mm Hg pneumoperitoneum using CO gas. The amount of CO was measured. Neuromuscular blockade with rocuronium was performed during the surgery and patient-controlled analgesia was also applied. Postoperative pain was assessed four times for 24 hours using a 10-point visual analogue scale.
The mean laparoscopic time was 75.65±38.19 minutes and the mean amount of CO gas used was 415.70±190.68 L. The mean score on the postoperative pain scale was 6.37±1.48 for 12 hours (sum of measurements taken at 6 and 12 hours after the surgery) and 11.72±2.46 for 24 hours (sum of measurements at 6, 12, 18, and 24 hours). In the statistical analysis, there were no correlations between the amount of CO used and pain scores for 12 and 24 hours postoperatively. There were no correlations between laparoscopic time and pain scores for 12 or 24 hours postoperatively. There were also no correlations between operative method and pain scores for 12 or 24 hours postoperatively.
We recorded the amount of CO gas used for each laparoscopic surgery. There was no correlation between the amount of CO used and postoperative pain. The lack of correlation may have been because the surgery was performed under anesthesia with deep neuromuscular blockade.
我们测量了泌尿外科腹腔镜手术中使用了多少 CO 气体，并研究了气体量是否与术后疼痛有关。
463 例患者由一名外科医生进行泌尿外科腹腔镜手术。所有手术均采用经腹腔入路，在 15mmHg 气腹下使用 CO 气体。测量 CO 气体的量。手术期间使用罗库溴铵进行神经肌肉阻滞，并应用患者自控镇痛。术后 24 小时内使用 10 分制视觉模拟评分法（VAS）评估 4 次疼痛。
腹腔镜时间的平均值为 75.65±38.19 分钟，CO 气体使用量的平均值为 415.70±190.68L。术后疼痛评分的平均值为 6.37±1.48（术后 6 小时和 12 小时测量值之和）12 小时，11.72±2.46（术后 6、12、18 和 24 小时测量值之和）24 小时。在统计学分析中，CO 气体使用量与术后 12 小时和 24 小时疼痛评分之间无相关性。腹腔镜时间与术后 12 小时和 24 小时疼痛评分之间无相关性。手术方法与术后 12 小时和 24 小时疼痛评分之间也无相关性。
我们记录了每例腹腔镜手术中 CO 气体的使用量。CO 气体使用量与术后疼痛之间无相关性。这种缺乏相关性可能是由于手术在深度神经肌肉阻滞的麻醉下进行。
