Background: Morbidly adherent placentation (MAP) increases the risk for obstetric hemorrhage. Cesarean hysterectomy is the prevalent perioperative approach. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a minimally invasive and relatively simple endovascular procedure to temporarily occlude the aorta and control below diaphragm bleeding in trauma. It has been effectively used to reduce obstetric hemorrhage.

Objectives: To evaluate whether REBOA during cesarean delivery (CD) in women with morbidly adherent placentation is a safe and effective treatment modality.

Methods: We introduced REBOA for CD with antepartum diagnosis of MAP in 2019 and compared these patients (RG) to a standard approach group (SAG) treated in our center over the preceding year, as a control. All relevant data were collected from patient electronic files.

Results: Estimated blood loss and transfusion rates were significantly higher in SAG; 54.5% of SAG patients received four RBC units or more vs. one administered in RG. No fresh frozen plasma, cryoprecipitate, or platelets were administered in RG vs. mean 3.63, 6, and 3.62 units, respectively in SAG. Ten SAG patients (90.9%) underwent hysterectomy vs. 3 RG patients (30%). Five SAG patients (45%) required post-surgical intensive care unit (ICU) admission vs. no RG patients. Bladder injury occurred in five SAG cases (45%) vs. 2 RG (20%). One RG patient had a thromboembolic event. Perioperative lactate levels were significantly higher in SAG patients.

Conclusions: Use of REBOA during CD in women with MAP is safe and effective in preventing massive bleeding, reducing the rate of hysterectomy, and improving patient outcome.

Background: The incidence of spinal failure necessitating general anesthesia and endotracheal intubation following spinal anesthesia for cesarean section is extremely low. Aspiration prophylaxis prior to spinal anesthesia is often recommended in case of spinal failure or excessive spinal block requiring the emergency administration of general anesthesia.

Objectives: To determine the incidence of endotracheal intubation following spinal anesthesia for cesarean section.

Methods: We retrospectively reviewed the pen-operative course of parturients undergoing cesarean section under spinal anesthesia at our institution from February 1991 to December 1993. If spinal failure occurred, 10 ml of sodium bicarbonate was administered by mouth prior to induction of general anesthesia.

Results: Among the 743 cases that we reviewed, spinal failure occurred in 15 patients (2%) because of inadequate analgesia in 14 patients (1.9%) and unexpected prolonged surgery for hysterectomy in one patient (0.1%). No patient required intubation due to excessive spinal block. In none of the patients was a record of pulmonary aspiration identified.

Conclusions: The extremely low incidence of spinal failure or excessive block necessitating endotracheal intuba­tion suggests that routine aspiration prophylaxis may not be necessary prior to spinal anesthesia. However, these results should be confirmed by a prospective, controlled study on larger populations. An antacid should be readily available and administered whenever general anesthesia is required.

Background: Charts of fetal measurements are widely used in the follow-up of pregnant women, however no charts have been constructed for the Israeli population.

Objectives: To establish growth charts for fetal femur size and biparietal diameter.

Methods: A prospective cross-sectional study of 1,422 singleton pregnancies was conducted.

Results: A total of 1,143 pregnancies met the inclusion criteria. Femur length and biparietal diameter were measured. A linear cubic model was fitted to construct growth charts for the different centiles. The charts were compared with previously published data.

Conclusions: We have constructed new fetal measure­ment charts for femur length and biparietal diameter that are unique for the Israeli population. These charts have been found to be similar to those published for other Caucasian populations.
