Effect of postural drainage assisting trachea suction on meconium aspiration syndrome

Abstract

Objective To evaluate the effect of postural drainage assisting trachea suction on meconium aspiration syndrome. Methods Total 61 cases of asphyxia neonates with MAS who were born in our hospital from Jan,2007 to Dec,2008, were divided into control group (24 cases) and observing group( 37 cases). The neonates in control group had endotracheal suction directly after intubation. But the infant in observing group was treated with endotracheal suction after postural drainage. The amount of suction from endotracheal tube,the complication of MAS and the outcome of these newborns were evaluated. Results The total amount of meconium drainage from endotrachea in observing group was statistics significantly more than that in control group [( 2. 16 ± 1.82) ml vs ( 1.23 ± 0. 97 ) ml, P ＜ 0. 05 )]; The intubating times in observing group were statistical significantly less than that in control group[( 1.19 ± 0. 46) vs ( 1.79 ± 0. 83 ) times, P ＜0. 01 ). The incidence of complication in observing group was 8. 11% ,which was significantly lower than that in control group(29. 17% ,P ＜0. 05). There were shorter needing oxygen time [(21.30 ± 22. 38) h vs (52. 91 ±39. 20) h,P ＜0. 01]and shorter hospitalization days [(9. 24 ±3.94) d vs ( 14. 39 ±6. 49) d,P ＜0.01 )]in observing group than those in control group respectively. The mortality in control group was 4. 17%, and no death occurred in observing group. Apgar scores of the first minute was similar in both groups ( P ＞ 0. 05 ). But there was significant difference(70. 16% vs 58. 34% ,respectively;P ＜0. 05) in the fifth minute Apgar scoring of 8 ～ 10 scores between the observing group and the control group. Conclusion Postural drainage assisting endotracheal suction may remove meconium in trachea effectively, decrease the complications of MAS and shorten the oxygen days and hospitalization time.
