Bupivacaine Levels and Effects while Breastfeeding
Summary of Use during Lactation
Because of the low levels of bupivacaine in breastmilk, and it is not orally absorbed, amounts received by the infant are small and it has not caused any adverse effects in breastfed infants.
Bupivacaine during labor and delivery with other anesthetics and analgesics has been reported by some to interfere with breastfeeding. However, this assessment is controversial and complex because of the many different combinations of drugs, dosages and patient populations studied as well as the variety of techniques used and deficient design of many of the studies. In contrast, epidural bupivacaine begun after clamping of the umbilical cord appears to enhance breastfeeding success because of improved pain control. Overall it appears that with good breastfeeding support epidural bupivacaine with or without fentanyl or one of its derivatives has little or no adverse effect on breastfeeding success. Labor pain medication may delay the onset of lactation.
Maternal Levels. Bupivacaine milk levels were measured in 5 women who were given epidural bupivacaine analgesia (dosage not stated) for vaginal delivery. Bupivacaine was undetectable (<20 mcg/L) in all samples taken at 2, 8, 24 and 48 hours postpartum.
One woman received bupivacaine 50 mg intrapleurally, followed in 1 hour by a continuous infusion of 25 mg/hour for 5 days for operative and postoperative analgesia. Four milk samples were taken during the infusion. The milk bupivacaine level was 400 mcg/L at 6 hours after the bolus dose and approximately 200 mcg/L at 24, 48 and 72 hours after the bolus dose.
Twenty-two women received epidural lidocaine 2% and bupivacaine 0.5% for pain control during cesarean delivery. Lidocaine dosage averaged 82 mg (range 25 to 168 mg). Average milk bupivacaine concentrations were 90 mcg/L at 2 hours after delivery, 60 mcg/L at 4 hours after delivery and 40 mcg/L at 12 hours after delivery.
Twenty women undergoing cesarean section deliveries with epidural anesthesia were randomized to receive either bupivacaine 0.5% (n = 10) or levobupivacaine 0.5% (n = 10) in a single-blinded study. The drugs were given as 0.5 mL (2.5 mg) boluses as needed up to 150 mg (mean 82.5 mg). Blood and milk samples were obtained before and 0.5, 1, 2, 6, 12 and 24 hours after administration of the drugs. Bupivacaine was detected in breastmilk 30 minutes after administration, with the peak milk concentration of about 0.2 mg/L occurring at about 2 hours after administration. Levobupivacaine was almost at baseline level by 7 hours and absent from milk (<5 mcg/L) by 24 hours after the dose. The passage of levobupivacaine into breastmilk was virtually identical.
Infant Levels. One woman who was 10 months postpartum received bupivacaine 50 mg intrapleurally, followed in 1 hour by a continuous intrapleural infusion of 25 mg/hour for 5 days for operative and postoperative analgesia. Breastfeeding resumed postoperatively 22 hours after the start of the infusion. A serum sample taken from the infant 5 hours after the morning feeding on day 3 postoperatively (52.5 hours after the bolus dose) contained undetectable (lower limit not stated) amounts of bupivacaine by gas chromatography.
Effects in Breastfed Infants
Bupivacaine administered to the mother by intrapleural or epidural routes had no effect on 13 breastfed infants.
Effects on Lactation and Breastmilk
Thirty women who delivered by cesarean section received either spinal anesthesia (not defined) alone (n = 15) or spinal anesthesia plus bupivacaine (n = 15) by extradural infusion after clamping the umbilical cord. A bupivacaine bolus of 12.5 mg was followed by a continuous infusion of 17.5 mg/hour for 3 days postpartum. Patients who received bupivacaine had better pain relief as indicated by lower pain scores and a lower consumption of supplemental diclofenac for pain. Bupivacaine-treated patients also produced more milk per day than the untreated women, a difference that was statistically significant from day 3 to the end of the study on day 11 postpartum. The authors concluded that improved pain relief improved breastfeeding performance.
Twenty women who delivered by cesarean section received either bupivacaine alone or bupivacaine plus buprenorphine by extradural infusion after clamping the umbilical cord. A bupivacaine bolus of 12.5 mg was followed by a continuous infusion of 17.5 mg/hour for 3 days. The buprenorphine was given as a bolus of 200 mcg followed by 8.4 mcg/hour for 3 days. Patients started breastfeeding as soon as they were able to sit up. Both the amount of milk fed and infant weight increased in both groups over the first 10 days postpartum; however, the increases were greater in those who received bupivacaine alone.
A prospective cohort study compared women who received no analgesia (n = 63) to women who received continuous epidural analgesia with fentanyl and either bupivacaine 0.05 to 0.1% (n = 39) or ropivacaine (n = 13) during labor and delivery. The total dosage of bupivacaine was 31 to 62 mg and the average total infusion time from start to delivery was 219 minutes. The study found no differences between the groups in breastfeeding effectiveness or infant neurobehavioral status at 8 to 12 hours postpartum or the number exclusively or partially breastfeeding at 4 weeks postpartum.
A randomized, prospective study measured infant breastfeeding behavior following epidural or intravenous fentanyl during delivery in 100 multiparous mothers undergoing cesarean section and delivering fullterm, healthy infants. The epidural group received epidural bupivacaine 100 mg initially, followed by a continuous infusion of 25 mg/hour. The intravenous fentanyl group received a spinal injection of 15 to 20 mg of bupivacaine. A slight difference was seen in breastfeeding behavior between the groups, with the infants in the intravenous fentanyl group performing slightly worse than those in the epidural group. However, all mothers were able to breastfeed their infants at 24 hours. None had severe breastfeeding problems; 10 women in the epidural group reported mild or moderate problems and 7 women in the intravenous group reported breastfeeding problems. Twenty mothers in the epidural group and 14 in the intravenous group used supplemental bottle feeding, with the difference not statistically significant.
A randomized, but nonblinded, study in women undergoing cesarean section compared epidural anesthesia with bupivacaine to general anesthesia with intravenous thiopental 4 mg/kg and succinylcholine 1.5 mg/kg for induction followed by nitrous oxide and isoflurane. The time to the first breastfeed was significantly shorter (107 vs 228 minutes) with the epidural anesthesia than with general anesthesia. This difference was probably caused by the anesthesia's effects on the infant, because the Apgar and neurologic and adaptive scores were significantly lower in the general anesthesia group of infants.
A randomized, multicenter trial compared the initiation rate and duration of breastfeeding in women who received high-dose epidural bupivacaine alone, or one of two low-dose combinations of bupivacaine plus fentanyl. A nonepidural matched control group was also compared. No differences in breastfeeding initiation rates or duration were found among the epidural and nonmedicated, nonepidural groups.
A nonrandomized study in low-risk mother-infant pairs found that there was no difference overall in the amount of sucking by newborns, whether their mothers received bupivacaine plus fentanyl, or fentanyl alone by epidural infusion in various dosages, or received no analgesia for childbirth. In a subanalysis by sex and number of sucks, female infants were affected by high-dose bupivacaine and high-dose fentanyl, but male infant were not. However, the imbalance of many factors between the study groups makes this study difficult to interpret.
In a prospective cohort study, 87 multiparous women who received epidural bupivacaine and fentanyl for pain control during labor and vaginal delivery. A loading dose of 0.125% bupivacaine with fentanyl 50-100 mcg. Epidural analgesia is maintained using 0.0625% bupivacaine and fentanyl 0.2 mcg/mL. The median dose of fentanyl received by the women was 151 mcg (range 30 to 570 mcg). The women completed questionnaires at 1 and 6 weeks postpartum regarding breastfeeding. Most women had prior experience with breastfeeding, support at home and ample time off from work. All women were breastfeeding at 1 week postpartum and 95.4% of women were breastfeeding at 6 weeks postpartum.
A national survey of women and their infants from late pregnancy through 12 months postpartum compared the time of lactogenesis II in mothers who did and did not receive pain medication during labor. Categories of medication were spinal or epidural only, spinal or epidural plus another medication, and other pain medication only. Women who received medications from any of the categories had about twice the risk of having delayed lactogenesis II (>72 hours) compared to women who received no labor pain medication.
A randomized study compared the effects of cesarean section using general anesthesia, spinal anesthesia, or epidural anesthesia, to normal vaginal delivery on serum prolactin and oxytocin as well as time to initiation of lactation. Spinal anesthesia used bupivacaine 10 to 11 mg of hypertonic 5% bupivacaine solution and epidural anesthesia used 10 mL (50 mg) of 0.5% bupivacaine. After delivery, patients in all groups received an infusion of oxytocin 30 international units in 1 L of saline, and 0.2 mg of methylergonovine if they were not hypertensive. Patients in the general anesthesia group (n = 21) had higher post-procedure prolactin levels and a longer mean time to lactation initiation (25 hours) than in the other groups (10.8 to 11.8 hours). Postpartum oxytocin levels in the nonmedicated vaginal delivery group were higher than in the general and spinal anesthesia groups and serum oxytocin in the epidural group were higher than those in the spinal group.
A retrospective study in a Spanish public hospital compared the infants of mothers who received an epidural during labor that contained fentanyl and either bupivacaine or ropivacaine. Infants of mothers who received an epidural had a lower frequency of early breastfeeding.
A randomized, double-blind study compared three epidural maintenance solutions for labor analgesia in women receiving epidural analgesia during labor: bupivacaine 1 mg/mL, bupivacaine 0.8 mg/mL with fentanyl 1 mcg/mL, or bupivacaine 0.625 mg/mL with fentanyl 2 mcg/mL. At 6 weeks postpartum, the breastfeeding rate was 94% or greater in all groups, with no difference among them. All mothers delivered full-term infants and were highly motivated to breastfeed and almost all had vaginal deliveries.
