Abstract:
Objective To evaluate the effects of supine and prone position on ventilation function in neonates in the initial six-hour period after weaning. Methods Sixty-four neonates weaned from mechanical ventilation and with normal body temperature hospitalized from Sep. 2004 to Apr. 2006 in our NICU were randomly divided into prone group and supine group. All of them were oxygen administrated through head net, oxygen flow rate was adjusted continously to keep SpO2 at normal level by monitoring SpO2 and RR. FiO2、RR were recorded at 15 minutes,1 h,2 h,3 h,4 h,5 h,6 h after weaning. Arterial blood gas was meas-ured at 1 h ,6 h after weaning and A-aDO2, RI, OI were calculated. Results (1) At 1～6 h after weaning the values of FiO2 in prone group were significantly lower than those in the supine group(P<0.01). (2) After weaning there was a decreasing tendency of RR in the prone group and the significant decrease was found at 4 h ,5 h ,6 h compared with supine group (P<0.01). (3) At 1h and 6h after weaning, the value of PaO2 and OI were significantly higher and the value of A-aDO2, RI were lower in the prone group than in the supine group(P<0.05,P<0.01). (4) At 6 h the PaCO2 in prone group were obviously higher than that in supine group (P<0.05). Conclusion At first 6h after weaning prone position can improve ventilation functions.
