摘　　要：目的:探究腔镜气腹与无气腹手术对麻醉机CO_(2)吸收剂钠石灰中的临床影响性。方法:此次研究在本院中开展,以2022年1月~2023年5月手术全身麻醉患者为研究对象,按照术中有无应用CO_(2)气腹,对90例患者进行分组处理,对照组(45例)未开展CO_(2)气腹,观察组(45例)开展CO_(2)气腹。钠石灰更换标准是校准监护仪CO_(2)气体监测FiCO_(2)水平5%,呼气末二氧化碳分压、动脉血气值正常,比较两组患者钠石灰使用时间与重量以及呼气末CO_(2)分压水平。结果:观察组钠石灰有效使用时间较对照组显著更低(P<0.05),但在钠石灰更换后重量对比中,观察组与对照组差异并不明显(P>0.05);观察组呼气末CO_(2)分压水平较对照组更高(P<0.05)。结论:与无气腹腔镜全身麻醉手术不同的是CO_(2)气腹会缩短麻醉机中CO_(2)吸收剂钠石灰的有效时间时长,建立CO_(2)气腹的腔镜手术操作中,FiCO_(2)水平达到5%后,会快速升高呼气末二氧化碳分压水平,此时,钠石灰安全更换时间窗窄,要求临床医师在发现更换钠石灰时需尽早处理,避免患者发生高碳酸血症等不良后果。Objective:To explore the clinical effects of laparoscopic pneumoperitoneum and pneumoperitoneum-free surgery on sodium lime as CO_(2)absorbent in anesthesia machine.Methods:This study was carried out in our hospital.From January 2022 to May 2023,90 cases were divided into groups according to whether CO_(2)pneumoperitoneum was used during operation.The control group(45 cases)did not carry out CO_(2)pneumoperitoneum,while the observation group(45 cases)carried out CO_(2)pneumoperitoneum.The replacement standard of sodium lime is to calibrate the monitor to monitor FiCO_(2)level by 5%,and the end-expiratory carbon dioxide partial pressure and arterial blood gas value are normal.The use time and weight of sodium lime and the end-expiratory carbon dioxide partial pressure level of the two groups are compared.Results:The effective use time of sodium lime in the observation group was significantly shorter than that in the control group(P<0.05),but there was no significant difference between the observation group and the control group in weight comparison after sodium lime replacement(P>0.05).The end-expiratory partial pressure of CO_(2)in the observation group was higher than that in the control group(P<0.05).Conclusion:Different from gasless laparoscopic general anesthesia,CO_(2)pneumoperitoneum will shorten the effective time of CO_(2)absorbent sodium lime in anesthesia machine.In the endoscopic operation of establishing CO_(2)pneumoperitoneum,when FiCO_(2)level reaches 5%,which requires clinicians to deal with it as soon as possible when finding replacement of sodium lime to avoid adverse consequences such as hypercapnia.
