- Abstract: Objective To investigate the impacts of sevoflurane combined with lung protective ventilation strategy on pulmonary ventilation function and lung compliance in obese patients undergoing laparoscopic weight loss surgery.Methods 60 obese patients underwent laparoscopic weight loss surgery were randomly divided into two groups.The control group was given lung protective ventilation intervention alone during anesthesia,and the study group was given sevoflurane inhalation anesthesia combined with lung protective ventilation intervention.Arterial blood was collected before tracheal intubation(T0),5 min after tracheal intubation(T1),40 min after tracheal intubation(T2)and 5 min after tracheal extubation(T3)for blood gas analysis.The pulmonary ventilation function and lung compliance of patients in the two groups were compared.Results Peak airway pressure(Ppeak)and plateau airway pressure(Pplat)at T2 were lower in the study group than those in the control group,and the differences were statistically significant(P<0.05);At T2 and T3 time points,the dynamic lung compliance(Cldyn)of the study group was higher than that of the control group,and the differences were statistically significant(P<0.05);7 days after surgery,the forced vital capacity(FVC)and forced expiratory volume in one second(FEV1)in the study group were higher than those in the control group,and the differences were statistically significant(P<0.05);At time points T1,T2 and T3,the levels of serum transforming growth factor-β1(TGF-β1),interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α)in the study group were lower than those in the control group(P<0.05);After surgery,the awakening time,spontaneous breathing recovery time,and extubation time in the study group were shorter than those in the control group,the number of adverse events during the recovery period was less than that in the control group,after awakening,the Ramsay score was lower than that in the control group(P<0.05).Conclusion The combination of sevoflurane and lung protective ventilation strategy can reduce inflammatory response,improve pulmonary ventilation function,and improve lung compliance in obese patients undergoing laparoscopic weight loss surgery,with good safety and fast postoperative recovery.
