Application of Shallow suction in mechanical ventilation among neonates

Abstract

Objective To observe the effect of shallow suction of endotracheal in ventilated neonates . Methods Eighty-six infants, from June 2012 to March 2013, were divided into observation group and control group using the random number table .The 40 infants in control group were used for traditional suction;the 46 infants in observation group were used for Shallow suction .The difference of interval time of suctions , trachea mucosal injury , frequency of artificial airway block , changes of heart rate and SpO 2 were compared between the two groups .Results The total times of sputum suction were 296 in observation group and 252 in control group .＆amp;nbsp;In observation group , the frequency of SpO 2 below 85% among infants was 5 times, which was less than 33 times in control group.The difference was significant （χ2 =27.44, P ＆lt;0.05）.The time of suction was （8.10 ±1.36）s in observation group and （12.50 ±1.46）s in control group, and the difference was significant （t=2.650, P＆lt;0.05）.The frequency of trachea mucosal injury was 12 times in control group, compared to 0 in observation group, which was significantly different （χ2 =14.410,P ＆lt;0.05）.However, there was no obvious difference in heart rate , interval time between suctions and artificial airway block （χ2/t =1.217, 0.761,0.003,P＆gt;0.05）.Conclusions The shallow suction of endotracheal is benefit in shortening the suction time, decreasing the frequency of hypoxemia , reducing the influence of airway and the mucosal injury , compared with traditional suction .Thus, we recommend that the shallow suction is worthy to being widely used in clinical interventions .
