Complications The main complications arising from dilatation and curettage are: 1. Hemorrhage 2. Uterine perforation 3. Infection 4. Miscellaneous—Asherman’s syndrome, infertility Anticipating excessive blood loss is critical in keeping this to a minimum. The evacuation of the uterus after an incomplete first trimester miscarriage is different from an incomplete second trimester loss. The latter is notorious for hemorrhage, which can easily lead to hypovolemic shock. An intravenous line with an ergotoxic agent (pitocin or ergometrine) readily available is imperative with second trimester evacuation. This is even more important in the presence of a septic uterus, a situation that renders the contractile ability of the myometrium reduced. Furthermore, the surgeon must always be prepared to perform a bimanual massage of the uterus as an adjunct to facilitate uterine contraction and subsequent

This procedure will serve well the surgeon who is already handicapped by lack of available transfusion services. Uterine perforation is probably the most feared complication of dilatation and curettage (Figs. 3 and 4). This can range from innocuous and benign to potentially disastrous and fatal consequences. It occurs most frequently in the pregnant uterus at the time of uterine sounding and or dilatation of the cervix in the pregnant or nonpregnant retroverted uterus. Again, the key to reduce these risks is to recognize the possibilities and choose the patients carefully. In an uncooperative patient performing a dilatation and curettage under local anaesthesia is already a complication. An alternative approach using a general anaesthesia is prudent. The patient’s history usually gives a clue, and the pelvic examination confirms the size and position of the uterus. If the patient is anxious and nervous and denies or does not readily admit to sexual activity, this should alert the surgeon to potential problems. Uterine perforation can be managed conservatively if detected early. This should be done as an inpatient with an intravenous line, no oral intake and monitoring of vital signs regularly for about a 24-hour period. Persistent or worsening pelvic-abdominal pain may indicate the need for a more aggressive management. Signs of peritoneal irritation such as rebound tenderness in the presence of a temperature rise may indicate a perforated bowel, which would require surgical intervention through laparotomy. Sepsis is a constant companion in an abnormal pregnancy. Patients commonly present to the clinic after having tried home remedies or local therapies. Although uncommon in the developed world, tetanus is still seen as a complication in the developing world. Human immunodeficiency virus (HIV) is the new and probably most worrisome infective agent for surgeons working in these areas and taking all necessary precautions is prudent. 14
