Abstract:
Objective To observe the effect of the continuous low pressure suctioning unite intermittent high pressure suctioning on drainage of subglottic secretions in the patients with artificial airway.Methods Using random number table,a total of 44 patients were evenly and randomly divided into observation group and control group.In the control group,continuous low pressure suctioning was performed to clear away the subglottic secretions.In the observation group,continuous low pressure suctioning combined with intermittent high pressure suctioning were performed.The average daily drainage volume of subglottic secretion,the incidence of early onset VAP (Ventilatorassociated pneumonia),the frequence of cough,the incidence of the airway mucosal damage,the incidence of the clogging of the drainage tube were investigated and compared between two groups.Results The average daily drainage volume of subglottic secretion in the observation group (52.80 ±4.181)ml was significantly more than in the control group (33.00 ± 2.675) ml (t =16.656,P ＜ 0.05).The incidence of early onset VAP in the observation group (10.0％) was significantly less than in the control group (40.0％) (x2 =4.800,P ＜ 0.05).There was no statistical difference in the frequence of cough between the observation group (1.93 ± 1.023) times and the control group (1.75 ± 1.006) times (t =0.771,P ＞ 0.05).There was no statistical difference in the incidence of the mucosal damage of airway between the observation group (15％) and the control group(10％) (x2 =0.229,P ＞0.05).The incidence of the clogging of the drainage tube in the observation group (0.0％) was significantly less than in the control group (20.0％) (x2 =4.444,P ＜0.05).Conclusions Continuous low pressure suctioning combined with intermittent high pressure suctioning can significantly improve the effect of drainage of the subglottic secretions by increasing the drainage volume,reducing the clogging of the drainage tube and the early onset of VAP.
