Zorluk: ZorLabor, Delivery, and Puerperium

A 29-year-old multiparous patient at 39 weeks gestation undergoes a spontaneous vaginal delivery. During the third stage of labor, excessive traction is applied to the umbilical cord before placental separation. The patient suddenly develops severe lower abdominal pain and profuse vaginal bleeding. On physical examination, a firm, beefy-red mass is protruding from the introitus, and the uterine fundus is not palpable transabdominally. The patient is tachycardic and hypotensive.

Arrange the following management steps in the optimal chronological sequence, assuming each initial intervention is unsuccessful until surgical resolution is required, followed by standard post-correction care.

  1. 1Discontinue ongoing uterotonic agents and establish large-bore intravenous access.
  2. 2Attempt immediate manual replacement of the uterus via the vagina.
  3. 3Administer a uterine relaxant (e.g., nitroglycerin or terbutaline).
  4. 4Proceed to laparotomy for surgical repositioning.
  5. 5Administer continuous intravenous uterotonic agents to maintain uterine tone.

Cevap

The correct sequence is: 1) Discontinue uterotonic agents and establish IV access; 2) Attempt immediate manual replacement; 3) Administer a uterine relaxant; 4) Proceed to laparotomy for surgical repositioning; 5) Administer continuous uterotonic agents.
The correct sequence for managing an acute uterine inversion follows a stepwise escalation to restore normal anatomy while minimizing hemorrhage. The first step is always to discontinue any uterotonics (which would trap the uterus) and stabilize the patient with fluids. Immediately after, manual replacement (Johnson maneuver) is attempted. If this fails due to a contracted cervical ring, a uterine relaxant (e.g., nitroglycerin) is given to facilitate replacement. If pharmacological relaxation also fails, laparotomy for surgical repositioning is required. Finally, once the uterus is successfully returned to its normal position (via any method), uterotonics must be administered to maintain a firm contraction, control bleeding, and prevent the uterus from reinverting.

Adım Adım Çözüm

1
Identify the clinical diagnosis based on the presentation.
Diagnosis of acute uterine inversion.
The patient has a beefy-red vaginal mass, absent abdominal fundus, and shock following excessive umbilical cord traction.
2
Determine the immediate initial management.
Stop uterotonics, call for help, and start IV fluids.
Uterotonics will contract the cervix, trapping the inverted fundus. IV fluids are critical for hypovolemic shock.
3
Determine the first-line intervention for repositioning.
Attempt immediate manual replacement.
Vaginal repositioning (Johnson maneuver) is the quickest and least invasive method, most successful before the cervical ring contracts.
4
Determine the next step if manual replacement fails.
Administer uterine relaxants.
Medications like nitroglycerin or terbutaline relax the cervical ring, allowing another attempt at vaginal repositioning.
5
Determine the intervention if pharmacological relaxation fails.
Surgical repositioning.
Refractory inversion requires surgical traction on the round ligaments (e.g., Huntington procedure) to restore anatomy.
6
Determine the post-repositioning care.
Administer continuous uterotonics.
Once the anatomy is restored, the uterus must be firmly contracted to prevent reinversion and control hemorrhage.
