Abstract:
Objective To investigate the respiratory mechanics and treatment outcomes of different types of mechanical ventilation for patients with neonatal acute respiratory distress syndrome(ARDS):the high frequency oscillation ventilation + pulmonary surfactant (HFOV+PS),conventional mechanical ventilation + pulmonary surfactant(CMV+PS),conventional mechanical ventilation(CMV). Methods Seventy-five cases with neonatal ARDS,25 cases in the HFOV+PS group,30 cases in the CMV+PS group,20 cases in the CMV group. Patients in the former two groups received 70 mg/kg PS at a time. PaO2,PaCO2,PaO2/FiO2,oxygenation index(OI)and respiratory index(RI)were detected at 0 h,12 h,24 h,48 h,72 h post-mechanical ventilation. Results At 12, 24,and 48 hours post-mechanical ventilation,patients in the HFOV+PS group had a significantly higher level of PaO2 and a significantly lower level of PaCO2 than those of patients in the CMV+PS group and the CMV group(P<0.05). At 12,24,48,and 72 hours post-mechanical ventilation,patients in the HFOV+PS group had a significantly higher level of PaO2/FiO2 and significantly lower level of OI and RI than those of patients in the CMV+PS group and the CMV group (P < 0.05,respectively). Patients in the HFOV+PS group also had significantly shorter durations of mechanical ventilation and oxygen usage than those of patients in the CMV+PS group and the CMV group (P < 0.05). No significant differences were observed in Gas leak,the incidence of intracerebral haemorrhage and cure rate among the three groups. Conclusions Application of HFOV with PS therapy for patients with neonatal ARDS can timely improve the oxygenation,shorten the time of mechanical ventilation and the usage of oxygen,without increasing complications.
