Some references regarding anesthesia (for mom) and breastfeeding

Andersen LW, Qvist T, Hertz J, Mogensen F. Concentrations of thiopentone in mature breast milk and colostrum following an induction dose. Acta Anaesthesiol Scand 1987 Jan;31(1):30-2. “Concentrations of thiopentone in mature breast milk and colostrum following anaesthesia induction… may be regarded as negligible and therefore non-toxic for the nursing infant.”

Baka NE, Bayoumeu F, Boutroy MJ, Laxenaire MC. Colostrum morphine concentrations during postcesarean intravenous patient-controlled analgesia. Anesth Analg. 2002 Jan;94(1):184-7.

Borgatta L, Jenny RW, Gruss L, Ong C, Barad D. Clinical significance of methohexital, meperidine, and diazepam in breast milk. J Clin Pharmacol 1997 Mar;37(3):186-92. “The amounts of methohexital, meperidine and diazepam excreted into breast milk do not warrant interruption of breast-feeding.”

Clin Pharmacol Ther. 2006 Jun;79(6):549-57. “The amount of midazolam, propofol, and fentanyl excreted into milk within 24 hours of induction of anesthesia provides insufficient justification for interrupting breast-feeding.”

Ortega D, Viviand X, Lorec AM, Gamerre M, Martin C, Bruguerolle B. Excretion of lidocaine and bupivacaine in breast milk following epidural anesthesia for cesarean delivery. Acta Anaesthesiol Scand 1999 Apr;43(4):394-7. “Our study does not reveal any adverse reactions related to the excretion of local anesthetics into breast milk. This study documents the magnitude of excreted lidocaine, bupivacaine and PPX in breast milk, and indicates that the use of both lidocaine and bupivacaine for epidural anaesthesia is safe with regard to breast-feeding.”

Schneider P, Reinhold P. Anesthesia in breast feeding. Which restrictions are justified? Anasthesiol Intensivmed Notfallmed Schmerzther 2000 Jun;35(6):356-74. From the abstract: “Thus it will be possible to anesthetize a breast-feeding mother with minimal risks for the child without giving up the advantages of mother milk. Through careful selection of appropriate drugs even elective operations don’t need to be postponed and breastfeeding can be continued as soon as in the immediate postoperative period.”
