Abstract：Objective To investigate the application efficacy of a self-developed detachable manual back-tapping expectoration device in patients with pulmonary infections in neurosurgery department.Methods From December 2021 to July 2022,60 patients with pulmonary infections in neurosurgery were prospectively collected and divided into the observation group and the control group based on the admission sequence,with 30 cases in each group.On the basis of conventional symptomatic treatment,the observation group utilized a self-designed detachable manual back-tapping expectoration device for back-tapping and expectoration,while the control group adopted traditional manual back-tapping.The main observation indicators encompassed the respiratory rate,blood oxygen saturation,and the results of lung CT reexaminations after back-tapping and expectoration.Results Compared with the control group,the respiratory rate of patients in the observation group was significantly decreased(P<0.01),the blood oxygen saturation was significantly increased(P<0.01),and the reexamination of lung CT revealed better absorption of the lesions(P<0.01).Additionally,when the operators used the back-tapping expectoration device,the tapping frequency within 3 minutes was significantly reduced(P<0.01),and the operational comfort was significantly enhanced(P<0.01).Conclusion For patients with pulmonary infections in neurosurgery,the detachable manual back-tapping expectoration device can effectively facilitate expectoration,maintain airway patency,enhance the therapeutic effect,and alleviate the labor intensity of the operators.
