Podcast Summary: The OB/GYN Resident Survival Guide

Episode #12: Manage Postpartum Hemorrhage Like a Pro (Part 2): Meds, Devices, and Surgical Management

Host: Dr. KC Miller
Date: May 17, 2025

Overview

This episode is the second part of a comprehensive guide on postpartum hemorrhage (PPH), focusing on the high-yield, practical management strategies OB/GYN residents need to know after initial interventions fail. Dr. KC Miller discusses the pharmacologic, mechanical, and surgical steps for controlling PPH, integrating ACOG guidelines, textbook “pearls,” and real-world insights. The tone remains practical and encouraging, supporting listeners in both exam preparation and real-time clinical scenarios.

Key Discussion Points & Insights

1. Context and Recap (01:23)

• Dr. Miller recaps the previous episode, highlighting that this part picks up after initial bedside interventions (e.g., bimanual massage, bladder drainage, laceration repair, removal of retained products) have failed to control brisk bleeding.
• The focus now shifts to “What do you do next?”

2. Pharmacologic Interventions – Uterotonics & TXA (02:43)

Mainstay Uterotonics:

• Three main medications:
  • Methyl ergonovine (Methergine)
  • 15-methyl prostaglandin F2α (Hemabate)
  • Misoprostol (Cytotec)
• No clear evidence any one is superior; selection should be contextual.
• Speed of onset guides choice:
  • Methergine: 2-5 minutes
  • Hemabate: 15-60 minutes
  • Cytotec: ~30 minutes

Clinical approach:

• Dr. Miller prefers starting with Methergine for its rapid onset, then proceeds with rectal Cytotec if bleeding continues, and considers adding Hemabate as needed.

Memorable Quote:
“I’ll usually start with Methergine because it takes about two to five minutes to work… If I start with Methergine and the bleeding is still ongoing, I’ll usually then place Cytotec rectally because I’m going to want to give it time to actually start working.”
— Dr. KC Miller (03:30)

Resource Tip:
“Table 3 in the previously mentioned practice bulletin, 183, reviews dosing, route, frequency, contraindications and adverse effects of these medications and you should save that table for review.”
— Dr. KC Miller (04:24)

Tranexamic Acid (TXA):

• Not a uterotonic. It’s an anti-fibrinolytic with IV onset in 5-10 minutes.
• Based on the WOMAN Trial (2017): Giving 1g TXA within 3 hours of birth reduces mortality from PPH.
• ACOG: Suggests TXA if medical therapy fails—“the sooner the better,” as efficacy diminishes with time.

“The ACOG suggests that TXA should be considered in the setting of obstetric hemorrhage when initial medical therapy fails. And really the sooner the better, given that the efficacy seemed to be reduced the farther away from delivery that it was administered.”
— Dr. KC Miller (05:24)

3. Mechanical Interventions – Uterine Tamponade (06:01)

Main devices:

• Bakri Balloon:

  • Inserted transcervically, inflated with up to 500cc saline.
  • Usually left for several hours (up to 24 hours max).

• Intrauterine Vacuum (Jada Device):

  • Now often preferred over Bakri at Dr. Miller’s institution.
  • Inserted into uterus, applies low-level suction to force contractions.
  • Typically left in for 1-3 hours (not exceeding 24 hours).

“We actually pretty much stopped using the Bakri balloon where I work altogether in favor of the Jada device… instead of inflating a balloon… you actually place the device on a low level suction and this sort of forces the uterus to contract.”
— Dr. KC Miller (07:02)

Less Preferred Mechanical Methods:

• Uterine Foley balloon (too small for effective tamponade)
• Uterine packing (with or without thrombin; suboptimal)

4. Last Resort Options – Interventional Radiology and Surgery (08:06)

Interventional Radiology:

• Uterine artery embolization for persistent, slow bleeding in hemodynamically stable patients.

Surgical Management:

• Exploratory laparotomy for ongoing brisk bleeding, uncontrolled PPH, or unstable patients.
  • Activate mass transfusion protocol.
  • Consult Gyn Oncology and/or Trauma Surgery as needed.

Intraoperative Techniques:

• Ligation of bilateral uterine arteries (O’Leary suture)
• Ligation of utero-ovarian ligament vessels
• Rarely, internal iliac artery ligation (requires retroperitoneal dissection; usually by subspecialists)
• Uterine compression sutures (B-Lynch, Cho, Hayman)

“You can apply uterine compression sutures like the B-Lynch, Cho or Haman sutures, and those essentially squish the uterus onto itself, tamponading those vessels.”
— Dr. KC Miller (09:31)

Definitive Treatment:

• Hysterectomy as absolute last resort when all else fails.

“After all of the above has failed, as a very last but definitive resort, you can perform a hysterectomy… gyn/onc or trauma surgery should be notified and the mass transfusion protocol activated if not already done.”
— Dr. KC Miller (10:00)

5. Summary & High-Yield Review (10:25)

• Definition:

  • Cumulative blood loss ≥1L or any blood loss with hypovolemia symptoms within 24 hours → “primary” PPH

  • 24 hours post-delivery → “secondary” PPH

• Causes:

  • Most common is uterine atony.
  • Others: lacerations, retained placenta, abnormal placentation, coagulopathy, and inversion

• Prevention:

  • Active management of third stage: oxytocin, fundal massage, controlled cord traction

• Stepwise Management:

  • Initial: Massage, bladder drainage, laceration repair
  • Uterotonics (Methergine, Hemabate, Cytotec) for atony
  • Mechanical tamponade or intrauterine vacuum
  • TXA within 3 hours post-delivery
  • Interventional radiology (embolization) or surgical: ligation, compression sutures, hysterectomy if all fails

Notable Quotes & Timestamps

• “None of these [uterotonics] have been shown to be superior to one another, so you can really start with any of them.” (03:02)
• “Tranexamic acid… when compared with placebo… reduced mortality in those patients with obstetric hemorrhage.” (05:07)
• “We actually pretty much stopped using the Bakri balloon… in favor of the Jada device.” (07:02)
• “You can apply uterine compression sutures…and those essentially squish the uterus onto itself.” (09:31)
