Zorluk: OrtaObstetric Complications

A 28-year-old G3P3 woman experiences sudden cardiovascular collapse and a large gush of vaginal bleeding immediately following the vaginal delivery of a healthy infant at 39 weeks of gestation. Physical examination reveals a beefy red, smooth mass protruding from the introitus. The uterine fundus cannot be palpated on abdominal examination. Her blood pressure is 75/40 mm Hg and pulse is 130/min. Intravenous fluids and blood products are rapidly initiated. Arrange the following steps in the correct escalation sequence for the definitive management of this patient's condition.

  1. 1Attempt immediate manual replacement of the uterus
  2. 2Administer a uterine relaxant (e.g., intravenous nitroglycerin) if initial manual reduction fails
  3. 3Proceed to surgical repositioning via laparotomy if pharmacological relaxation is insufficient
  4. 4Administer uterotonic agents to maintain uterine tone and prevent recurrence

Cevap

The correct sequence is: (1) Attempt immediate manual replacement, (2) administer a uterine relaxant if needed, (3) proceed to surgical repositioning if manual methods fail, and (4) administer uterotonic agents once the uterus is reverted.
The standard escalation protocol for acute uterine inversion begins with an immediate attempt at manual replacement. If unsuccessful, uterine relaxants are given to facilitate manual reduction. If pharmacological relaxation fails, surgical repositioning (laparotomy) is required. Once the uterus is successfully reverted by any method, uterotonic agents are administered to maintain uterine tone and prevent reinversion.

Adım Adım Çözüm

1
Identify the clinical diagnosis.
The presentation of a protruding vaginal mass, absent uterine fundus, and profound shock postpartum indicates acute uterine inversion.
Accurate diagnosis is required to initiate the specific management algorithm.
2
Determine the initial definitive intervention.
Attempt immediate manual replacement of the uterus.
Prompt manual reduction is often successful if performed immediately before a cervical contraction ring forms.
3
Determine the next step if initial reduction fails.
Administer a uterine relaxant (e.g., nitroglycerin).
Uterine relaxation resolves the cervical constriction ring, facilitating manual replacement.
4
Determine the surgical step if pharmacological relaxation fails.
Proceed to laparotomy for surgical repositioning.
Refractory cases require surgical intervention to physically revert the uterus.
5
Determine the final maintenance step.
Administer uterotonic agents.
Once reverted, the uterus must be kept firmly contracted to prevent recurrence and control bleeding.
