Clinical Study of CO2 Absorbent in Anesthesia Machine for Laparoscopic Pneumoperitoneum and Pneumoperitoneum-Free Surgery
Objective:To explore the clinical effects of laparoscopic pneumoperitoneum and pneumoperitoneum-free surgery on sodium lime as CO2 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 CO2 pneumoperitoneum was used during operation.The control group(45 cases)did not carry out CO2 pneumoperitoneum,while the observation group(45 cases)carried out CO2 pneumoperitoneum.The replacement standard of sodium lime is to calibrate the monitor to monitor FiCO2 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 CO2 in the observation group was higher than that in the control group(P＜0.05).Conclusion:Different from gasless laparoscopic general anesthesia,CO2 pneumoperitoneum will shorten the effective time of CO2 absorbent sodium lime in anesthesia machine.In the endoscopic operation of establishing CO2 pneumoperitoneum,when FiCO2 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.
