随着微创外科的发展,腹腔镜全子宫切除术(total laparoscopic hysterectomy,TLH)以其创伤小、术后恢复快等优势,已广泛应用于临床[1]。TLH是指在腹腔镜下将子宫体及子宫颈完全切除,并经阴道将切除的子宫取出,之后在腹腔镜下缝合阴道断端及盆腔腹膜[2]。人工气腹是腹腔镜手术成功的保证,二氧化碳(CO2)以其溶解性好、弥散速度快、成本低等特点而成为建立人工气腹的标准气体[3]。人工气腹为术者提供清晰的术野,且CO2气腹压力越高,手术视野越清晰[4]。行TLH术时,由于病变增大的子宫占据大部分盆腔,往往更需较高的气腹压力维持清晰的手术视野,保障手术的安全。然而关于CO2气腹对病人呼吸、循环及胃肠系统功能的不良影响的观点已达成共识,且这种不良影响与气腹压力的高低及高气腹压持续时间成正比关系[5]。既往有研究[6]在10 mmHg气腹压力下成功实施前列腺癌根治手术,但关于根据手术进展适时调节CO2气腹压力在TLH中鲜见相关报道。故本文设手术全程气腹压力14 mmHg为对照组,研究依据手术进展先14 mmHg后10 mmHg调节气腹压力在全子宫切除中的应用,以期为今后更好开展此项手术,为其他类似腹腔镜手术气腹压力的调节提供参考依据,进一步明确调节气腹压力先14 mmHg后10 mmHg的安全压力范围。现作报道。

摘要:
目的探讨在腹腔镜全子宫切除术中适时调节二氧化碳(CO2)气腹压力对病人舒适度及手术效果的影响。 方法选择行腹腔镜全子宫切除手术的60例病人为研究对象,按照随机数字表法分为观察组和对照组,各30例。观察组手术开始至子宫切下前气腹压力设置为14 mmHg,子宫切下后压力调低至10 mmHg,并维持此压力直至手术结束;对照组建立气腹后气腹压力设置为14 mmHg,并且术中一直维持此压力不变直至手术结束。对比分析2组术中阴道残端及腹膜缝合时间、术后24 h内通过视觉模拟评分评价肩部疼痛情况、住院时间以及医生对手术视野暴露评分。 结果观察组术中缝合阴道残端及腹膜的时间、术后24 h内肩部疼痛评分、住院时间均低于对照组,差异有统计学意义(P < 0.01);医生对术中手术视野暴露评分比较,2组差异无统计学意义(P>0.05)。 结论腹腔镜全子宫切除手术中,在保证安全操作和不影响手术视野的情况下,先调节气腹压力14 mmHg切除病变子宫,再将气腹压力调低至10 mmHg,可以缩短缝合时间,提高病人舒适度,缩短住院时间,促进病人康复。 Abstract:ObjectiveTo explore the effect of timely adjustment of carbon dioxide(CO2) pneumoperitoneum pressure on the comfortableness and surgical effect of patients in total laparoscopic hysterectomy. MethodsA total of 60 patients with total laparoscopic hysterectomy were selected as the research objects.All patients were randomly divided into experimental group and control group according to the random number table method, with 30 cases in each group.In the experimental group, the pneumoperitoneum pressure was set at 14 mmHg from the beginning of operation to before the hysterectomy, then the pressure was reduced to 10 mmHg after hysterectomy, and maintained this pressure until the end of the operation.In the control group, the pneumoperitoneum pressure was set to 14 mmHg after the establishment of pneumoperitoneum, and the pressure remained unchanged during the operation until the end of the operation.The time of suture of vaginal stump and peritoneal suture, the score of shoulder pain by visual simulation within 24 h after surgery, the length of hospital stay and the score of intraoperative visual field exposure were compared and analyzed. ResultsThe time of suture of vaginal stump and peritoneum, shoulder pain score within 24 hours and hospital stay in the observation group were significantly lower than those in the control group(P < 0.01).There was no significant difference in the intraoperative visual operative field exposure score between the two groups(P>0.05). ConclusionsIn total laparoscopic hysterectomy, the pneumoperitoneum pressure should be adjusted first to 14 mmHg to remove the affected uterus, and then the pneumoperitoneum pressure should be lowered to 10 mmHg, which can shorten the suture time and improve patient comfort, shorten hospital stay and promote patient recovery. -
