PIP: The case report of a fatal result in an abortion requested because X-ray diagnostic studies of the gallbladder and intestine had been made during an undiagnosed early pregnancy is presented. A uterine vacuum aspirator had not been purchased by the hospital. A portable laboratory vacuum pump with an appropriate suction trap was used. The apparatus had been used previously in several abortion cases. After dilatation of the cervix and insertion of the aspirating cannula, the pump was turned on. A sudden massive effusion of bloody froth issued from around the cannula. The cannula was removed immediately. It was found that the tubing had been incorrectly connected. The aspirator tube was connected with the pressure outlet of the pump. The tubing was then correctly placed and the uterus emptied. The patient was given succinyl choline, intubated, placed in the Trendelenburg position, and monitored cardiographically. About 30 seconds after the uterine insufflation blood pressure became unobtainable. The pulse slowed to 50 beats/minute and respiration diminished. Cardiac ausculation revealed no sounds. Respiration was maintained using oxygen through an endoctracheal tube. The pulse was still palpable and the EKG showed abnormal QRS complexes. Cyanosis then became evident. Closed chest cardiac massage was used for 1 minute but the patient became pulseless and QRS complexes were bizarre. Then the chest was opened and each ventricle was needled. From each ventricle of the distended heart air hissed under pressure through the needle vent site. The ascending aorta was needled and air escaped under pressure. Cardiac color and action improved when aided by massage. Iv isoproterenol and intracardiac epinephrine were given. An electric defibrillator converted the cardiac rhythm to a sinus rhythm. Norepinephirne brought about hypertension. Blood and albumin were given iv. The patient never regained consciousness. Tracheostomy and a feeding gastrostomy were required. Urinary and respiratory infections followed and the patient died after 2 1/2 months. Autopsy revealed tracheobronchitis, bronchopneumonia, and pulmonary edema. The brain showed extensive cerebral cortical necrosis. The heart was normal. This maternal death was preventable.
