Can a pregnant patient in labor with a history of anaphylaxis to Percocet (oxycodone) and Tramadol be given Nubain (nalbuphine) or Fentanyl?

From the Guidelines

For a pregnant patient in labor with a history of anaphylaxis to Percocet (oxycodone) and Tramadol, Fentanyl is the preferred alternative pain management option due to its shorter half-life and minimal effect on fetal heart rate. According to the most recent guidelines, opioid agonist-antagonists like Nalbuphine (Nubain) can be continued in certain clinical circumstances, but its use near delivery may cause neonatal respiratory depression 1. Fentanyl, on the other hand, can be administered as 25-100 mcg IV doses every 1-2 hours as needed or via patient-controlled analgesia.

Key Considerations

• Prior to administration, ensure the anesthesia team is aware of the patient's allergies, document them prominently in the chart, and have emergency medications like epinephrine readily available.
• While cross-reactivity between different opioid classes is uncommon, careful monitoring is still essential during initial administration of any pain medication in patients with prior opioid allergies.
• Nubain can be given as 10-20 mg IV/IM every 3-6 hours, but its use should be cautiously considered due to potential risks.

Medication Administration

• Fentanyl is typically preferred in labor due to its pharmacokinetic profile, which allows for more controlled and safer administration.
• The choice between Fentanyl and Nubain should be individualized based on patient-specific factors, including the severity of pain and the proximity to delivery.

Safety Precautions

• Concomitant use of certain medications, such as serotonergic agents, amphetamines, or MAO inhibitors, with Nubain may result in increased risk of serotonin syndrome 1.
• The patient's medical history and current medications should be thoroughly reviewed to minimize potential drug-drug interactions and ensure safe administration of the chosen pain management option.

From the Research

Anaphylaxis to Percocet and Tramadol

• A patient with a history of anaphylaxis to Percocet (oxycodone) and Tramadol may require alternative pain management options during labor.
• The provided studies do not directly address the use of Nubain (nalbuphine) or Fentanyl in patients with a history of anaphylaxis to Percocet and Tramadol.

Use of Fentanyl in Labor Analgesia

• Fentanyl has been studied in combination with local anesthetics such as ropivacaine and bupivacaine for labor analgesia 2, 3, 4.
• These studies suggest that fentanyl can be used effectively and safely in combination with local anesthetics for labor analgesia.
• However, the safety of using Fentanyl in a patient with a history of anaphylaxis to Percocet and Tramadol is not directly addressed in the provided studies.

Use of Nubain in Labor Analgesia

• There is no mention of Nubain (nalbuphine) in the provided studies.
• Therefore, there is no evidence from these studies to support or refute the use of Nubain in a patient with a history of anaphylaxis to Percocet and Tramadol.

Alternative Pain Management Options

• The provided studies suggest that patient-controlled epidural analgesia (PCEA) with local anesthetics such as ropivacaine and bupivacaine can be an effective and safe option for labor analgesia 5, 6, 2, 3, 4.
• However, the use of these options in a patient with a history of anaphylaxis to Percocet and Tramadol would require careful consideration and consultation with an anesthesiologist or other qualified healthcare professional.
