Abstract:
Objective? To explore the application of three-way connection in air bag pressure monitoring in patients with artificial airway. Methods? Totally 85 patients who received artificial airway formechanical ventilation in the 4th People＇s Hospital of Shenyang from August 2016 to July 2017 were selected and randomized into two groups in whichminimum hermetically sealed pressure (MOP) was used in the air bag to seal the airway. The artificial airway balloon for the observation group (n=43) was connected to a balloon pressure meter by three-way connection to monitor the pressure in the balloon, while the artificial airway balloon for the observation group (n=42) was connected to a balloon pressure meter by direct connection to monitor the pressure in the balloon. The changes of balloon pressure (△P=MOP-monitoring pressure) at 4, 8, 24 and 48 h post air inflation were monitored in both groups. The incidence of regurgitation and aspiration, airway mucosal injury and pulmonary infection were observed in the two groups. Results? There was no statistically significant difference in △P between the two groups at 4 h post air inflation[△P 4 h: (3.76±1.47) vs. (3.82±1.36) cmH2O; (P＞0.05)]. The△P 8, 24 and 48 h of the observation group were lower than those of the control group, and there was statistically significant difference between the two groups [△P 8 h: (5.76±2.58) vs. (7.29±2.42) cmH2O; △P 24 h: (6.32±3.08) vs. (9.38±3.32) cmH2O; △P 48 h: (8.79±5.26) vs. (15.32±5.87) cmH2O; (P＜0.01)]. The incidence rate of regurgitation and aspiration in the observation group was 9.3%, lower than that in the control group, which was 11.9%, and there was statistically significant difference between the two groups (P＜0.05); there was no statistically significant difference in the incidence rate of airway mucosal injury and pulmonary infection between the two groups (P＞ 0.05). Conclusions? The use of three-way connection can reduce air leakage of the artificial airway balloon and reduce the incidence rate of regurgitation and aspiration effectively.
