T raumatic injury is the principle non-obstetric cause of maternal death. 1,2 Seven percent of pregnant women suffer from trauma. 3 Approximately 3 to 10% sustain injuries secondary to penetrating trauma. 4 -7 The maternal mortality rate resulting from penetrating trauma is less than 5%. Fetal mortality, however, can be as high as 70%, which is a result of direct missile injury or the effects of prematurity. 3,8 Emergent Cesarean delivery is indicated if the uterus obstructs the operative field or the viable fetus is in distress. The question remains whether expectant obstetric management is feasible when open abdominal management is deemed necessary for maternal care. Currently there are no guidelines that discuss open abdominal management for the pregnant trauma patient.The following is a report of a pregnant woman at 29 weeks gestation with an open abdomen status post-gunshot wound (GSW) to the abdomen and chest. Operative decision making, open abdomen management, and damage control therapy are discussed. The use of temporary abdominal closure using the vacuum technique in a patient with a gravid uterus has not been previously reported.
CASE REPORTA 20-year-old, gravida 1, woman sustained multiple GSWs to the right chest and abdomen. The patient was 29 weeks pregnant and complaining of abdominal pain. Examination revealed a healthy, young woman with a Glasgow Coma Scale score of 15 in no acute distress. Her vital signs upon arrival to the emergency room were a blood pressure of 127/91 mm Hg, heart rate of 115 bpm, respiratory rate of 18 breathes/min, and O 2 saturation of 99% on room air.On primary survey, her chest examination revealed present and equal breath sounds bilaterally. The patient was tachycardic. Her heart sounds were regular in rhythm, and no murmurs or rubs were detected on auscultation. Two GSW were seen on the right breast, located on lateral and medial sides of the areola, respectively. A tangential GSW was present in the center of her chest between both breasts. Her abdomen was firm. The gravid uterus was symmetrically enlarged and consistent with reported gestational age. A right flank entrance GSW was present with no apparent exit wound. Fetal heart tones (FHT), assessed by the obstetric/ gynecology team in the emergency department, were present at 140 bpm.Laboratory data revealed a hematocrit of 27.6 vol%, a normal basic metabolic rate, and normal coagulation studies. Arterial blood gas results were pH 7.47, CO 2 36, O 2 230, HCO 3 26.5, base excess 2.7, lactate 1.3 mEq/ L, and O 2 saturation 100% on a 4-L nasal cannula. Anteroposterior roentgenogram of the chest was negative for pneumo/hemothorax.The patient was taken to the operating room for exploratory laparotomy. Under general endotracheal anesthesia, a midline incision along the full length of the abdomen was made. Intraoperative findings included a large hemoperitoneum (Ͼ1 L), an enlarging retroperitoneal hematoma caused by transection of the engorged right gonadal vessels, and a through-and-through GSW to the cecum.
