Anesthesia and Breastfeeding

I get a lot of questions from my friends about receiving anesthesia while breastfeeding.  As more moms are breastfeeding, I think it’s an important question to tackle for the baby’s safety.  I’ve included references and summarized key points below.  If you have any questions, please do not hesitate to ask your anesthesiologist or physician who will be taking care of you.

Key Points:

  • Intrathecal and epidural anesthesia and opioids are ok for breastfeeding mothers.
  • Acetaminophen, ibuprofen, and ketorolac are ok because they have relatively short half-lives.
  • Celecoxib: ok.
  • Naproxen: ok.
  • Propofol is ok.  Proceed with breastfeeding when mom is awake after anesthesia.
  • Midazolam (sedation dose) is ok.  Proceed with breastfeeding when mom is awake after anesthesia.
  • Fentanyl is short-acting enough.  Proceed with breastfeeding when mom is awake after anesthesia.
  • Avoid meperidine in the post-operative unit – its metabolites have long half-lives.
  • Hydromorphone has a long half-life (10hours).  Best to avoid this medication or pump and dump.
  • Morphine: low dose is ok.  Caution if using morphine PCA.
  • Hydrocodone: dosage should be <30mg/day in breastfeeding moms.
  • Oxycodone: dosage should be <30mg/day in breastfeeding moms or not used at all.
  • Tramadol: ok. But FDA not recommend for breastfeeding moms (USA).

Things to Consider

  • Try to have your case booked as early in the morning to decrease the amount of time for fasting.
  • Pump a stash of breast milk ahead of surgery for 1 day of feeds just in case.  You can always use this expressed milk later.
  • Breastfeed or express milk just before the start of the procedure.
  • Have an adult supervise you post-operatively as well as the baby in case there are signs of medication transferred to the baby.
  • Consider anesthetic techniques (local anesthesia, regional anesthesia, non-narcotics, etc.) to minimize opioid consumption.

 

 

Methadone and acute and chronic pain management

We had a journal club where we discussed this article: Anesthesiology, May 2017; Clinical effectiveness and safety of intraoperative methadone in patients undergoing posterior spinal fusion surgery: a randomized, double-blinded, controlled trial.

  • IV Methadone 0.2 mg/kg vs IV hydromorphone 2mg at surgical closure in 2+ level spinal fusion
  • Decreased postop IV and opioid requirements and pain scores.  Improved patient satisfaction

Questions:

  1. Is there a pain service following these patients postoperatively?
  2. Exclusions: do you include OSA and BMI>45 patients?
  3. Is ETCO2 and PCA enough to combat respiratory depression on the floor?
  4. Are any discharged on the same day after receiving this dose — think total knees and single level lamis?
  5. Will this improve or worsen the opioid epidemic?
  6. Are surgeons on board with tackling pain multimodally for the benefit of the patient?
  7. For pain follow-up, are there psychiatry, homeopathy, palliative care, PT, holistic approaches for the patient?

 

Methadone Dose Conversion Guidelines

Intraop Lidocaine for postop pain

Intraop Ketamine for postop pain
