Abstract: Objective To investigate the effect of lung protective ventilation in laparoscopic radical nephrectomy in the elderly patients. Methods A total of 106 patients with primary renal cancer who received laparoscopic radical nephrectomy in our hospital from October 2020 to October 2021 were enrolled and randomly divided into the control group and the lung protective ventilation group, with 53 cases in each group. The control group received general anesthesia and routine intraoperative ventilation, while the lung protective ventilation group received general anesthesia and intraoperative lung protective ventilation. Lung compliance[peak pressure (Ppeak), airway plateau pressure (Pplat), oxygenation index (PaO2/FiO2), lung dynamic compliance (Cdyn)], serum inflammation and oxidative stress [interleukin-6(IL-6), interleukin-8(IL-8), tumor necrosis factor α (TNF-α), malondialdehyde (MDA), superoxide dismutase (SOD)], hemodynamic indicators [systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR)] and the incidence of complications between the two groups were compared. Results The levels of Ppeak, Pplat, IL-6, IL-8, TNF-α, MDA, SBP, DBP and HR in lung protective ventilation group were lower than those in control group, while the levels of SOD, PaO2/FiO2 and Cdyn levels were higher than those in control group(all P<0.05) 2 h after pneumoperitoneum and after surgery. The total incidence rate of the complications in lung protective ventilation group was lower than that in control group(P<0.05). Conclusions The application of lung protective ventilation in laparoscopic radical nephrectomy in elderly patients can improve intraoperative lung compliance, reduce inflammatory stress response, improve hemodynamics and reduce postoperative complications.
