Abstract:
Objective To explore the effects of two methods of air-impact on clearing the subglottic secretion in patients with intubation.Methods A simple random sampling method was used to select 106 patients underwent mechanical ventilation through oral tracheal intubation in intensive medicine department from September 2016 to October 2017.The recruited patients were divided into two groups by the random number table,53 patients in Group A were treated with breath-holding key of a ventilator,combined with air-bag inflation and deflation,and 53 patients in Group B were treated with simple breathing apparatus combined with manual technique to clear subglottic secretion.The incidence of ventilator-associated pneumonia(VAP),amount of cleared subglottic secretions,difference of vital signs before and after operation,number of coughing,in vitro training time and operation time were compared between groups.Results The intention-to-treat ana]ysis(ITT) showed that the incidence of VAP in Group A and B were 7.55％ and 5.66％,the per-protocol analysis(PP) showed that the incidence of VAP in Group A and B were 3.92％ and 3.85％,and there was no significant difference between groups(P＞0.05);the amount of cleared subglottic secretions in two groups were (8.31±0.82) ml,(7.97±1.12)ml,and there was no significant difference (P＞ 0.05);but vital signs before and after operation,number of coughing,in vitro training time and operation time in Group A were lower than those in Group B,and the differences were statistically significant(P＜0.05).Conclusion Two methods of air-impact can both effectively reduce the incidence of VAP,but using breath-holding key of a ventilator combined with airbag inflation and deflation has less influence on vital signs,which patients can better tolerate and medical staff can master and cooperate more easily.
