In this 216th episode I discuss case reports of using Lipid Emulsion Therapy for Amniotic Fluid Embolus. Big thanks to Dr. Adam Olson for bringing this to my attention!

  1. Jed,
    Thank you for reviewing this topic! A few weeks ago I helped my anesthesia team in caring for an Emergency Cesarean Section for a patient with known placenta increta. A general anesthesia was planned with MTP ordered and hysterectomy to follow. Approximately 20min after the baby was delivered the patient had a sudden drop in ETCO2, BP and SpO2. We suspected at the time she had an AFE, so we implemented the A-OK treatment immediately along with 100% FiO2. Atropine however was held since her HR was in the 130s. After about 15min of minimal-no improvement and multiple doses of epinephrine 100mcg, 1L crystalloid, additional IV access and arterial line placement I suggested we consider intralipid in light of the studies you mentioned in your podcast.

    We administered a bolus of intralipid (30cc IVP drawn off the bag). Within roughly 60 seconds of the bolus, the patient had a rapid improvement in her ETCO2 (up to 35 from 15mmHg), SpO2 (up to 95% from 74%) and BP (up to 100/68 from 66/33). We continued the infusion of intralipid to finish off the 250mL bag and kept her on 100% FiO2 until she was consistently stable. We drew lab work to perform a TEG on her which showed stable clotting factors, so additional blood products were held. She remained intubated and transferred to ICU for further workup. In the ICU, TTE was negative in detecting any emboli and serum sample to detect amniotic fluid was also negative.

    We are left to think this patient therefore had a Venous Air Embolism instead given her abrupt cardio-pulmonary compromise and the exposure of large vessels during her hysterectomy. Nonetheless, the intralipid seemed to provide a profound improvement in her hemodynamics and resolve her V/Q mismatch.

    Given this patient’s dramatic improvement after giving intralipid I wanted to share with you my case and welcome your questions and feedback.
