Clinical analysis of different anesthesia methods for pulmonary infection after perioperative operation

The purpose is to explore the effect of different anesthesia methods on pulmonary infection after the operation. 120 patients who underwent surgery from January 2015 to August 2018 were selected in three groups: group A (n=40), group B (n=40), and group C (n=40). Group A was given inhalation anesthesia, group B was given total intravenous anesthesia, and group C was given epidural block combined with general anesthesia. In addition to lung imaging examination, the postoperative parameters of patients such as leukocyte count and mean arterial pressure were recorded. Through image analysis, the case of pulmonary infection after epidural block combined with general anesthesia was 1, while that of inhalation anesthesia and intravenous injection was 7 and 8. In terms of the fluctuation of heart rate and mean arterial pressure, patients in group C had lower levels of heart rate and mean arterial pressure, while patients in groups A and B had higher levels of these parameters. There was no significant difference between inhalation anesthesia and intravenous injection for pulmonary infection after the operation. Thus, it can be concluded that the negative effects of epidural block combined with general anesthesia are much less than those of the other two anesthesia methods, which has the smallest effect on pulmonary infection after the operation. Therefore, the epidural block combined with general anesthesia has the smallest effect on pulmonary infection after the operation. This study is of great significance, and more anesthesia methods can be further studied in subsequent works.
