ABSTRACT
Objective:
To evaluate the effect of epidural labor analgesia administration methods on occurrence of postpartum urinary retention in nulliparous parturients through a comparison between programmed intermittent epidural bolus (PIEB) and continuous epidural infusion.Methods:
Two hundred nulliparous parturients who were at full term with a singleton fetus in vertex presentation, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, aged 22-35 yr, with body mass index of 22.4-42.6 kg/m 2, were divided into 2 groups ( n=100 each) using a random number tablemethod:
continuous epidural infusion group (group CEI) and group PIEB.Patient-controlled epidural analgesia (PCEA) was performed in active phase of labor (cervical dilatation≥1 cm) during the first stage of labor.The PCEA solution contained the mixture (10 ml) of 0.1% ropivacaine with 0.5 μg/ml sufentanil.The PCEA pump was set up to deliver a 5-ml bolus dose with a 30-min lockout interval.The analgesia solution contained the mixture (100 ml) of 0.08% ropivacaine and sufentanil 0.5 μg/ml.In group CEI, the drugs were given at 8 ml/h immediately after the initial dose.PIEB regimens were programmed as 8 ml over 80 s once an h after the initial bolus, and the administration was stopped after delivery of fetus.The labor time, consumption of analgesia solution and the incidence of postpartum urinary retention were recorded.Results:
Compared with group CEI, the duration of the second stage of labor was significantly shortened, and consumption of analgesia solution and the incidence of postpartum urinary retention were decreased in group PIEB ( P<0.05).Conclusion:
Compared with the continuous epidural infusion, the application of PIEB in labor analgesia can reduce the incidence of postpartum urinary retention in nulliparous parturients.
