Abstract:
Objective To observe the effects of implementing lung protective ventilation strategies on lung dynamic compliance and oxygenation function in elderly emergency surgery patients.Methods A total of 126 elderly patients undergoing emergency surgery admitted to Northern Jiangsu People's Hospital from December 2021 to December 2022 were selected.They were randomly divided into an observation group and a control group,with 63 patients in each group,using a random number table method.All selected cases underwent general anesthesia mechanical ventilation during surgery.The control group chose conventional ventilation mode,while the observation group adopted lung protective ventilation.The lung dynamic compliance,oxygenation function,inflammatory indicators,and complications of the two groups of patients were compared.Results Within 30 minutes of surgery,the mean airway pressure(Pmean)and peak airway pressure(Ppeak)levels of both groups of patients increased compared to preoperative levels.The observation group had a smaller increase than the control group(P<0.05),and the pulmonary dynamic compliance(Cdyn)levels were lower than preoperative levels.The observation group had a lower increase than the control group(P<0.05).After 2 hours of surgery,the levels of Pmean and Ppeak in both groups of patients decreased compared to 30 minutes during surgery,and the decrease in the observation group was smaller than that in the control group(P<0.05).The levels of Cdyn in both groups decreased compared to before surgery,and the observation group was lower than that in the control group(P<0.05).24 hours after surgery,the blood oxygen saturation(SpO2)and arterialpartial pressure of oxygen(PaO2)levels in both groups of patients decreased compared to before surgery,and the observation group was lower than the control group(P<0.05).The alveolar-arterial oxygen partial pressure difference[P(A-a)DO2]levels between the two groups increased compared to preoperative levels,and the observation group was higher than the control group(P<0.05).48 hours after surgery,the SpO2 and PaO2 levels in the observation group were higher than those in the control group,and the P(A-a)DO2 levels were lower than those in the control group(P<0.05).24 hours after surgery,the serum C-reactive protein(CRP)and white blood cell(WBC)levels in both groups were significantly increased compared to preoperative levels,and the observation group was higher than those in the control group(P<0.05).48 hours after surgery,the serum CRP and WBC levels of both groups of patients decreased compared to 24 hours after surgery,and the observation group was lower than the control group(P<0.05).The incidence of complications in the observation group was lower than that in the control group(7.94％vs.25.40％)(P<0.05).Conclusion Implementing lung protective ventilation strategies for elderly emergency surgical patients is beneficial for improving lung dynamic compliance and oxygenation function,inhibiting the release of inflammatory cytokines,reducing the incidence of postoperative pulmonary complications,and effectively exerting lung protective effects.
