[source] On the ropivacaine-reducing effect of low-dose sufentanil in intrathecal labor analgesiaACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 8 2010C. M. ORTNER Background: Combining ropivacaine with sufentanil for intrathecal (i.t.) analgesia in labor is well recognized, but information on dosing is limited. This study aimed to determine the ED 50 of i.t. ropivacaine and to assess the effect of adding defined low doses of sufentanil. Methods: This was a two-phase, double-blind, randomized and prospective study. One hundred and fifteen parturients receiving combined spinal epidural analgesia were allocated to one of four groups to receive ropivacaine or sufentanil alone or in combination. In phase one, sufentanil dose,response was calculated using logistic regression. In phase two, ED 50 of ropivacaine and of the combination with a fixed dosage of sufentanil at ED 20 and ED 40 was evaluated using the technique of up,down sequential allocation. Analgesic effectiveness was assessed 15 min after injection using a 100 mm visual analog scale, with <10 mm lasting for 45 min defined as effective. Furthermore, side effects and duration were recorded. Results: The ED 50 of i.t. ropivacaine was 4.6 mg [95% confidence intervals (95% CI) 4.28, 5.31]. Adding sufentanil at ED 20 significantly decreased the ED 50 of i.t. ropivacaine to 2.1 mg (95%CI 1.75, 2.5) (P<0.005); at ED 40, the reduction was similar (P<0.005). Combining sufentanil with ropivacaine resulted in a dose-independent prolongation of analgesia. Besides pruritus, which was well tolerated, there were no differences in side effects. Conclusion: Adding sufentanil at ED 20 results in a more than 50% dose-sparing effect of ropivacaine and considerably prolongs analgesia. Increasing dosage implicates no clinical benefit. [source] Patient-controlled epidural technique improves analgesia for labor but increases cesarean delivery rate compared with the intermittent bolus techniqueACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2004P. Halonen Background:, We tested the hypothesis that patient-controlled epidural analgesia for labor (PCEA) provides better analgesia and satisfaction than the intermittent bolus technique (bolus) without affecting the mode of delivery. Methods:, We randomized 187 parturients to receive labor analgesia using either the PCEA or bolus technique. The PCEA group received a starting bolus of 14 mg of bupivacaine and 60 µg of fentanyl in a 15-ml volume, followed by a background infusion (bupivacaine 0.08% and fentanyl 2 µg ml,1) 5 ml h,1 with a 5-ml bolus and 15-min lock-out interval. The bolus group received boluses of 20 mg of bupivacaine and 75 µg of fentanyl in a 15-ml volume. Results:, Parturients in the PCEA group had significantly (P < 0.05,0.01) less pain during the first and second stages of labor. There was no difference in the spontaneous delivery rate between the groups, but the cesarean delivery rate was significantly (P < 0.05) higher (16.3% vs. 6.7%) in the PCEA group than in the bolus group. Bupivacaine consumption was significantly (P < 0.01) higher (11.2 mg h,1 vs. 9.6 mg h,1) and the second stage of labor was significantly (P < 0.01) longer (70 min vs. 54 min) in the PCEA group than in the bolus group. Patient satisfaction was equally good in both groups. Conclusion:, The PCEA technique provided better pain relief. This was associated with higher bupivacaine consumption, prolongation of the second stage of labor, and an increased rate of cesarean section. [source] Maternal Analgesia During Labor Disturbs Newborn Behavior: Effects on Breastfeeding, Temperature, and CryingBIRTH, Issue 1 2001Anna-Berit Ransjö-Arvidson RNMTD Background:Newborns not exposed to analgesia, when placed on the mother's chest, exhibit an inborn prefeeding behavior. This study was performed to assess the effects of different types of analgesia during labor on the development of spontaneous breastfeeding movements, crying behavior, and skin temperature during the first hours of life in healthy term newborns.Methods:Video recordings were made of 28 newborns who had been dried and placed in skin-to-skin contact between their mother's breasts immediately after delivery. The video recordings were analyzed blindly with respect to infant exposure to analgesia. Defined infant behaviors were assessed every 30 seconds. Group 1 mothers (n = 10) had received no analgesia during labor, group 2 mothers (n= 6) had received mepivacaine via pudendal block, and group 3 mothers (n= 12) had received pethidine or bupivacaine or more than one type of analgesia during labor.Results:All infants made finger and hand movements, but the infant's massagelike hand movements were less frequent in infants whose mothers had received labor analgesia. A significantly lower proportion of group 3 infants made hand-to-mouth movements (p < 0.001), and a significantly lower proportion of the infants in groups 2 and 3 touched the nipple with their hands before suckling (p < 0.01), made licking movements (p < 0.01), and sucked the breast (p < 0.01). Nearly one-half of the infants, all in groups 2 or 3, did not breastfeed within the first 2.5 hour of life. The infants whose mothers had received analgesia during labor had higher temperatures (p= 0.03) and they cried more (p= 0.05) than infants whose mothers had not received any analgesia.Conclusions:The present data indicate that several types of analgesia given to the mother during labor may interfere with the newborn's spontaneous breast-seeking and breastfeeding behaviors and increase the newborn's temperature and crying.
