The effect of protective ventilation strategies on mechanical power during surgery and postoperative pulmonary complications in elderly patients
Objective To explore the effect of protective ventilation strategies on mechanical power during surgery and postoperative pulmonary complications in elderly patients.Method 102 elderly patients who underwent elective abdominal surgery in Beijing Hospital from 2019 to 2022 were selected as the study subjects.According to different intraoperative ventilation strategies,the study subjects were divided into control group(using traditional ventilation strategies,52 cases)and observation group(using protective ventilation strategies,50 cases).The intraoperative indexes and postoperative pulmonary complications in the two groups were compared and analyzed.Result There were no significant differences in fluid rehydration volume,blood loss,urine volume,operation time and mechanical ventilation time between the two groups(P>0.05).The tidal volume,plateau pressure,peak airway pressure and mechanical power in observation group were lower than those in control group,positive end-expiratory pressure and respiratory rate were higher than those in control group,with statistical significance(P<0.05).No pneumothorax occurred in the two groups after surgery,and the total incidence of postoperative pulmonary complications in the observation group was significantly lower than that in the control group,with statistical significance(P<0.05).Conclusion The use of protective ventilation strategy during surgery can reduce the intraoperative mechanical power of elderly patients,and reduce the occurrence of postoperative pulmonary complications.
