Emergent Cesarean Section in a Bandl's Ring Patient: An Obstetrics and Gynecology Simulation Scenario.

Bandl’s ring is a rare pathology, although its incidence is thought to be rising. Training curricula for treating this condition is almost nonexistent. Patients who present with this disease require specific management and treatment. Practicing these techniques in a medical simulation lab allows trainees to hone their skills in a safe, inconsequential environment. We present a simulated case in which a patient presents with a Bandl’s ring.

Pathologic Uterine Ring Associated With Fetal Head Trauma and Subsequent Cerebral Palsy

Pathologic uterine rings, also called Bandl's ring, are historically associated with obstructed labor and good neonatal outcomes. Two cases are presented involving a pathologic uterine ring identified at cesarean delivery, which led to fetal cranial trauma. At delivery, pathologic uterine rings were found to encompass the heads of both fetuses, with gross features of traumatic head deformity. Radiologic studies demonstrated intracranial hemorrhage predating delivery. Both infants developed cerebral palsy, which was initially attributed to hypoxic-ischemic encephalopathy from delivery despite normal umbilical arterial pH. Further investigation linked the intracranial bleeding to compressive trauma from the uterine rings. Although rare, pathologic uterine rings may cause traumatic cranial deformity and subsequent cerebral palsy.

A principle of physics as applicable to shoulder delivery

1.1. A wooden manikin, with shoulders too large to be delivered by pulling, is easily delivered according to a law of physics applicable to the screw.2.2. If the shoulders of a wooden manikin are so large that they can be delivered in only one way, it would seem that this way would be the easiest, and therefore the least dangerous, way to deliver a live baby.3.3. After the head has been born the shoulders of the baby resemble a longitudinal section of a screw engaged in three threads, the “pubic thread,” the “promontory thread,” and the “coccyx thread.”4.4. Any pulling on the baby's neck or axilla is mechanically incorrect because it violates a simple, well-known law of physics applicable to the screw.5.5. There is no stretching of the trapezius muscle, and consequently no danger of injuring the cervical nerves.6.6. The pressure is away from the perineum.7.7. This maneuver cannot be performed unless the posterior shoulder has passed the spines.8.8. Pressure from above, on the buttocks, must be applied by the operator (not an assistant) in order to synchronize the pressure of the two hands.9.9. The passage of a baby through the birth canal is, in the vast majority of cases, an engineering problem. By applying a law of physics applicable to the screw, we find that most of our difficulty is due to a “crossed thread” or improper inclination of some part of our screwlike object. For example, extension of the arms, or nuchal arms, in a breech delivery may prevent the shoulders from adopting the proper inclination or screwlike attitude necessary for delivery. In the vertex presentation extension of the arms along the baby's body may interfere with the proper inclination of the shoulders. A Bandl's ring does the same thing.

Calcium and quinine in labor and post-partum hemorrhage

1.1. The combination of calcium and quinine was apparently a little more effective than calcium gluconate alone.2.2. The intravenous route of administration alone was used in the patients receiving calcium gluconate, and in 6 of the patients receiving calgluquine. The response was more prompt than the intramuseular route, in that some of these had precipitate labors.3.3. The best results were obtained where the patients had ruptured membranes or were already having mild pains.4.4. No ill effects on the babies from the quinine were noted in this series; however, the dose was small.5.5. Three Bandl's rings were found. All had more or less cephalopelvic disproportion which was probably the principal factor in the Bandl ring.6.6. Patients with post-partum hemorrhage from atonic uteri that had not responded to the usual oxytocics had, as a rule, a marked hardening of the uterus and a lessening of the hemorrhage immediately after receiving intravenous calcium gluconate.
