Continuous balloon pressure monitoring in children with tracheal intubation after surgical repair of congenital heart disease / 中国小儿急救医学

ABSTRACT

Objective:To investigate the effect of continuous balloon pressure monitor in children with postoperative tracheal intubation after congenital heart disease(CHD).Methods:Children admitted to the intensive care unit after CHD surgery were selected and divided into two groups using a random number table.Under the same treatment principles, the intervention group used a continuous balloon pressure monitor to manage the balloon pressure, and the control group used a manual balloon pressure meter.The clinical outcomes of two groups were compared.Results:A total of 84 children were enrolled, including 40 in intervention group and 44 in control group.There were no significant differences in age, sex, intubation depth and intubation type between two groups(all P>0.05).The rates of ventilator leakage in the intervention and control groups were 17.5% and 20.5%, respectively, and the rates of misaspiration in two groups were 0 and 6.8%, respectively, with no statistically significant differences(all P>0.05).The duration of mechanical ventilation in intervention group was longer than that in control group[median ventilator time 44.0(41.7, 73.5)h vs.43.0(38.9, 60.5)h, P=0.024], but the rates of abnormal balloon pressure(10.0% vs.81.8%, P<0.001), the rate of laryngeal edema after withdrawal(2.5% vs.18.2%, P=0.031)and the rate of vocal difficulties(7.5% vs.25.0%, P=0.032)were lower than those in control group, and the differences were statistically significant. Conclusion:Continuous balloon pressure monitoring can automatically maintain balloon pressure in the normal range, reduce complications associated with artificial airways, and have a positive effect on the maintenance of the airway in children.
