RESUMO
Objective To study the effects of remifentanil with propofol and no positive pressure ventilation induction of anesthesia in 5 minutes-cesarean section on parturients and neonates. Methods Sixty pregnant women were randomly divided into ketamine anesthesia group (group L) and remifentanil anesthesia group (group R).In group L,anaesthesia was induced with ketamin 0.5 mg/kg+propofol 2 mg/kg and group R with remifentanil 1 μg/kg+propofol 2 mg/kg.Blood pres-sure,heart rate,oxygen saturation and pulse rate of maternal were recorded at intubation (T1 ),inci-sion (T2 ),and cutting the umbilical cord (T3 ).The infant Apgar scores at 1 minute and 5 minute af-ter birth,the delivery time of the fetus and umbilical blood gas values were recorded.Results The systolic blood pressure (SBP)and heart rate (HR)were significantly higher at T1 and T2 in group L than those in group R (P <0.05).The SBP,DBP and HR had not significant difference at T3 .The delivery time of the fetus and the infant Apgar scores at 1 minute and 5 minute between the two groups had no statistically significant differences.Conclusion Remifentanil combined with propofol and without positive pressure ventilation induction of anesthesia can be safely used in 5 minutes-cesar-ean section.The maternal hemodynamics is more stable without increasing the risk of neonatal respira-tory depression.
