Objective To investigate the effect of a continuous monitoring of balloon pressure on the prevention of ventilator-associated pneumonia(VAP).Methods A total of 93 patients with mechanical ventilation treated from January 2022 to June 2023 were selected as the study objects,and they were randomly divided into experimental group(47 cases)and control group(46 cases)by random number table method.Patients in the control group were intermittently monitored by a balloon pressure gauge,and those in the experimental group were continuously monitored by a balloon pressure monitor.The rate of balloon pressure control compliance,subglottic drainage flow,pepsin content in airway sputum,VAP and prognostic indexes were compared between the two groups.Results The balloon pressure compliance rate of the experimental group was significantly higher than that of the control group(99.12％vs 78.70％,X2=119.154,P＜0.05).On the first,second and third day of ventilation,the subglottic drainage flow in the experimental group was significantly higher than that of the control group(P＜0.05).At the time of intubation,and 48 h and 96 h after intubation,the pepsin content of the experimental group was significantly lower than that of control group(P＜0.05).The mechanical ventilation time and intensive care unit(ICU)stay time of the experimental group were significantly shorter than those of control group(P＜0.05).The incidence of VAP of the experimental group was significantly lower than that of the control group(17.02％vs 39.13％,X2=5.642,P＜0.05).Conclusion A continuous monitoring of balloon pressure can maintain the ideal pressure of artificial airway,improve the therapeutic effect of mechanical ventilation and reduce the incidence of VAP.
