Abstract Objective: To observe the effects of laryngeal mask combined with LPSV on lung function, pulmonary complications and serum SP-A in patients undergoing laparotomy. Methods: 60 patients who underwent elective laparotomy in General Department of our hospital from July 2018 to July 2020 were selected as the study object prospectively. The patients in the control group (30 cases) were divided into two groups randomly and simply by random, the control group (30 cases) as LPSV, and the observation group was laryngeal mask combined with LPSV (30 cases). The clinical indexes, pulmonary function indexes, pulmonary complications, serum biochemical factors were collected and compared. Results: There was no significant difference in clinical indexes between 2 groups (P>0.05). Ventilation indexes MVV, FVC, ventilation indexes PEF and FEF25 in the control group were significantly lower than those before surgery, the differences were statistically(P<0.05). Ventilation indexes FEF25 in the observation group were significantly lower than those before surgery, the differences were statistically significant (P<0.05). Ventilation indexes MVV, FVC, FEV1, ventilation indexes PEF and FEF25 in observation group were significantly higher than those in control group, the differences were statistically significant(P<0.05). The incidence of pulmonary infection, pleural effusion and atelectasis in the observation group were 3.33%, 0%, 0%, significantly lower than that in the control group 23.33%, 13.33%, 13.33%, the differences were statistically significant(P<0.05). Serum SP-A in 2 groups on day 1 after surgery was significantly higher than that before surgery and 7 days after surgery, the differences were statistically significant(P<0.05). The level of serum SP-A in the observation group was significantly lower than that in the control group on day 1 and day 7 after surgery, the differences were statistically significant(P<0.05). Conclusion: Laryngeal mask combined with PCV can reduce lung function injury, lung complication rate, and serum SP-A level.
