Abstract:
Objective To study the clinical effects of pulmonary recruitment maneuvers combined with pressure regulation volume control (PRVC) in the treatment of severe respiratory distress syndrome (RDS) in premature infants.Method From July 2015 to September 2016,preterm infants of grade Ⅲ-Ⅳ RDS who received PRVC treatment in neonatal department of Huai'an Maternal and Child Health Hospital were assigned into recruitment maneuver group and control group (without recruitment maneuver) using randon number table.The ventilator parameters were observed at 1,2,6,12,18 h and 24 h after ventilation.Recovery rate,duration of oxygen therapy and ventilation,duration of hospital stay,incidence of second dose of pulmonary surfactant and complications were compared between two groups.Result A total of 18 cases were included in recruitment maneuver group and 19 cases in control group.The recovery rate of recruitment maneuver group was higher than control group (16/18 vs.10/19).The duration of oxygen therapy [(6.6 ± 2.3) d vs.(11.8 ± 3.0) d],duration of ventilation [(4.1 ± 2.3) d vs.(6.4 ± 2.8) d],duration of hospital stay [(26.7 ± 7.0) d vs.(33.0 ± 8.4) d] in recruitment maneuver group were significantly shorter than control group (P ＜ 0.05).The proportion of bronchopulmonary dysplasia (1/18 vs.8/19),retinopathy of premature (1/18 vs.7/19),patent ductus arteriosus that require medication closure (1/18 vs.7/19)and incidence of second dose of pulmonary surfactant (2/18 vs.9/19) in recruitment maneuver group were significantly lower than control group (P ＜ 0.05).While the complication of air leak,necrotizing enteritis,Ⅲ-V grade intracranial hemorrhage showed no significant differences between the two groups (P ＞ 0.05).Conclusion Recruitment maneuvers combined with PRVC in treatment of severe RDS premature infants can improve recovery rate and oxygenation.It can also shorten the duration of oxygen therapy,ventilation and hospital stay.It can reduce the incidence of bronchopulmonary dysplasia and retinopathy of premature.It is worth spreading in clinical practice.reduce the incidence of bronchopuhmonary dysplasia and retinopathy.It is worthy of promotion.
