Abstract:
Objective To explore the effect of water analgesia on the pain relief for primiparas in labor, especially on the point of the acutest pain and total time of severe pains by tracking and comparing with remifentanil patient- controlled intravenous analgesia and the conventional vaginal delivery. Methods A total of 139 singleton and full-term primiparas who chosed analgesia labor were selected. There were 3 groups:56 cases in water analgesia group (hereinafter referred to shortly as water group), 37 cases in remifentanil patient-controlled intravenous analgesia group (hereinafter referred to shortly as vein group ) and 46 cases in traditional vaginal delivery group (hereinafter referred to shortly as traditional group). In addition, labor pain intensity was assessed with numerical rating scale (NRS). All groups were evaluated by NRS score in five different time points during the delivery:cervical dilation to 2-3 cm or 1 minute before labor analgesia; labor analgesia after 10 minutes; labor analgesia after 30 minutes; labor analgesia after 60 minutes;point of acutest pain. Meanwhile, total time of acutest pain, progress of labor, use of oxytocin, mode of delivery, postpartum hemorrhage and neonatal asphyxia were all observed. Results Comparison of labor progress and postpartum bleeding, mode of delivery and neonatal Apgar score in three groups of primipara showed no significant difference (P>0.05). Compared with the traditional group, the NRS score and point of acutest pain in water group obviously declined, the total time of severe pain shortened 36.58 min on average, which showed significant difference (t=-4.400, P<0.05). Compared with the vein group, the NRS score of water group at 10 minutes after labor analgesia was below the vein group (t=-2.358, P<0.05), so was point of acutest pain (t=-2.703, P<0.05). But the score of water group was higher than intravenous analgesia after 60 minutes, which showed significant difference (t=2.833, P<0.01). The rate of oxytocin application in water group was only 12.5%(7/56), significantly less than the rate in vein group, which was 37.84%(14/37), there were significant differences (χ2=8.182, P<0.05). Conclusions Water analgesia can effectively alleviate maternal pain and reduce intrapartum intervention, and more, less influence on maternal and newborn, and is a safe and effective analgesia method.
