Laboratory: blood type, Rh factor test, hematocrit measurement, Kleihauer-Betke test, coagulation studies, If greater than 20 weeks' gestation, monitor for contractions, If fewer than three contractions per hour, monitor for four hours, then discharge, If three to seven contractions per hour, monitor for 24 hours, then discharge, All Rh-negative patients should receive Rh immune globulin therapy unless the injury is remote from the uterus (e.g., isolated distal extremity), Perform manual uterine displacement, or 25- to 30-degree left lateral tilt, Decreased chest wall compliance with breast hypertrophy and diaphragmatic elevation, Use cricoid pressure, if assistance is available, Perform compressions higher on the sternum (slightly above center of sternum), Remove fetal and uterine monitors before defibrillation, Loss of adequate cardiac shock dose; produces skin burns at monitor sites, Heimlich maneuver; use chest thrust if unable to encircle the gravid abdomen, Start intravenous therapy above diaphragm, Early tracheal intubation; use short laryngoscope handle and smaller endotracheal tube, Difficult ventilation with pharyngeal edema, breast hypertrophy, diaphragmatic elevation, Consider other etiologies (e.g., magnesium toxicity), Consider left wide paddle, adhesive pad, or breast displacement, Dextrorotation of the heart; breast hypertrophy, Verify endotracheal tube with carbon dioxide detector, Esophageal detector more likely not to reinflate after compression, Tailor ventilator support to oxygenation and ventilation, Perform emergency hysterotomy after four minutes, Decreased aortocaval and venous compression, Continue all maternal resuscitative efforts (cardiopulmonary resuscitation, positioning, defibrillation, and drugs) during and after cesarean delivery. The maternal antibodies bind to fetal RhD positive erythrocytes, leading to hemolysis, anemia, hydrops fetalis, and possibly fetal death. A peripheral blood smear is made from the maternal postpartum sample and treated with acid. Smears are air dried between 1060 minutes, fixed in 80 vol% ethanol for 5 min at 20-22C, rinsed with tap water, and air dried. The patient should be monitored by tocodynamometry for a minimum of four hours.8,12 Eight or more contractions per hour were present in the first four hours of monitoring in 100% of patients with an ultimate diagnosis of placental abruption.8,9 If at least six contractions per hour are detected during the four-hour initial period, or the mechanism of injury presents a high degree of fetal risk,13 then 24 hours of monitoring is indicated.3,12 Before viability (23 to 24 weeks' gestation), the fetal heart should be monitored via intermittent Doppler auscultation, and after viability, continuous fetal monitoring should be performed.
