Application of Monitoring the Partial Pressure of Carbon Dioxide at the End of Expiration in Clinical Anesthesia during Laparoscopic Surgery
To explore whether the monitoring of end-expiratory partial pressure of carbon dioxide(PETCO2)can accurately reflect the level of arterial blood carbon dioxide under carbon dioxide pneumoperitoneum during laparoscopic surgery under general anesthesia.Methods:The clinical data of 80 patients undergoing laparoscopic surgery under general anesthesia admitted to the Affiliated Hospital of Xiangyang Vocational and Technical College from January 2021 to February 2023 were retrospectively analyzed.By monitoring the numerical changes of end-expiratory partial pressure of carbon dioxide(PETCO2)and arterial partial pressure of carbon dioxide(PaCO2)before and after carbon dioxide pneumoperitoneum,the correlation between them was analyzed,and the ability to find adverse events during the operation was recorded.Results:There were significant differences in the values of PETCO2 and PaCO2 before and after carbon dioxide pneumoperitoneum(P<0.05).On the other hand,the sensitivity of PETCO2 was significantly better than that of PETCO2 in detecting intraoperative adverse events(P<0.01).Conclusion:The monitoring of end-expiratory carbon dioxide partial pressure in clinical anesthesia can effectively reflect the change of carbon dioxide level in laparoscopic surgery under general anesthesia,with continuity,and can also find adverse events in surgery in time,which has high clinical value.
