Abstract:
Objective To investigate the efficacy of volume target pressure control(VTPC)and synchronized intermittent mandatory ventilation(SIMV)in treating severe neonatal respiratory distress syndrome(NRDS). Methods Fifty - six admitted cases with severe NRDS hospitalized in Jiangmen Central Hospital from October 2012 to March 2015 were randomly divided into 2 groups:28 cases in VTPC group were treated by VTPC and SIMV,and 28 cases in pressure control ventilation(PCV)group were treated by PCV and SIMV. There was no significant difference between 2 groups in terms of gender,gestational age,and birth weight(all P ﹥ 0. 05). Artery blood gas analysis was performed at 6 hours,12 hours,24 hours,and 48 hours respectively after ventilation. The following parameters were observed:the time of invasive mechanical ventilation,duration of oxygen therapy,mortality and the incidence rates of hypocapnia,pneumo-thorax,ventilator associated pneumonia( VAP),grade Ⅲ - Ⅳ periventricular intraventricular hemorrhage( PVH -IVH),periventricular leukomalacia(PVL)and bronchopulmonary dysplasia(BPD). Results No case in 2 groups withdrew from the test. There was no significant difference between 2 groups in terms of the first treatment time and total doses of poractant alfa injection(all P ﹥ 0. 05). The time of invasive mechanical ventilation in VTPC group[(71. 75 ± 9. 82)h]was shorter than that in PVC group[(97. 89 ± 16. 88)h](t = 7. 083,P = 0. 000). Hypocapnia incidence of four blood gas analysis in VTPC group[(19. 64 ± 14. 20)% ]was lower than that in PCV group[(47. 32 ± 18. 43)% ] (t = 6. 294,P = 0. 000). Incidence rates of VAP and PVL in VTPC group were lower than those in PCV group(χ2 =5. 197,P = 0. 023;χ2 = 4. 766,P = 0. 029). However,duration of oxygen therapy,mortality and the incidence rates of pneumothorax,Ⅲ - Ⅳ PVH - IVH and BPD were not significantly different between 2 groups( all P ﹥ 0. 05). Conclusion VTPC + SIMV has a better efficacy than PCV + SIMV in the treatment of NRDS.
