Abstract:
Objective To explore the factors related to the amount of suction under glottis, look for effective nursing counter measures in order to improve the suction effects. Methods A retrospective analysis of the clinical data of 71 patients with subglottic secretion drainage from 1st January 2013 to 1st May 2014 was performed. The secretion viscosity, posture, the endotracheal tube cuff pressure, patients restlessness, suction pressure, and acute physiology and chronic health evaluationⅡscore were set as independent variables. A multiple linear regression analysis was performed to screen factors that may lead to reduction of suction volume of subglottic secretion and nursing counter measures were planned and implemented accordingly. Results Secretion viscosity, supine, endotracheal tube cuff pressure and patient restlessness were the main reasons that influence the amount of suction under glottis(P<0. 05). Multiple linear regression equation:amount of suction of subglottic secretion/2 h(ml) =4. 868 +2. 470 × restlessness-1. 624 × secretion viscosity+0. 874 × endotracheal tube cuff pressure-0. 933 × posture. Conclusions Quantity of suction of subglottic secretion were positively correlated to patients′restlessness, secretion viscosity and endotracheal tube cuff pressure. Subglottic attract amount for the most when take left lateral position. Strengthening the control and intervention of related factors plays a very important role in the care of suction under glottis.
