Operative morbidity and reproductive outcome in secondary myomectomy: a prospective cohort study.

BACKGROUND: This prospective study was designed to evaluate the operative morbidity and reproductive outcome in patients who had secondary myomectomy for recurrent symptomatic uterine fibroids. METHODS: A total of 58 women were subjected to a secondary myomectomy via the abdominal route. The operative morbidity such as blood loss, presence of adhesions and febrile index were estimated and the pregnancy outcome over a 2-4 year period of follow-up. RESULTS: The mean age and standard deviation (+/- SD) of the women was 35 (+/- 2.4) years. Nineteen patients (33%) had a postoperative temperature vertical line 100 degrees F and the estimated blood loss ranged from 159-2500 ml (median 700 ml). Seven patients (12%) required blood transfusion and one had a hysterectomy due to haemorrhage. Nine women (15.5%) became pregnant but only five (56%) had live births. Those with successful pregnancies tended to be younger with a mean age of 31.8 (+/- 2.6) years versus 35 (+/- 1.8) years, (P = 0.08, non-significant) and had fewer uterine leiomyomata; median with range values, 2 (1-6) versus 7 (6-15). The variables which best predicted the postoperative likelihood of pregnancy were; age, presence of tubal adhesions and the number of uterine fibroids. CONCLUSION: This prospective study showed a high operative morbidity and a poor fertility outcome after a repeat myomectomy. The factors affecting successful outcome in a logistic regression model were age, tubal adhesions and number of uterine fibroids.

A randomized comparison of vasopressin and tourniquet as hemostatic agents during myomectomy.

OBJECTIVE: To assess the comparative efficacy of perivascular vasopressin and tourniquet in minimizing bleeding and its sequelae at myomectomy. METHODS: Between March 1994 and February 1995, 52 women with symptomatic uterine leiomyomas scheduled for myomectomy were entered into a randomized trial comparing vasopressin (26 patients) and tourniquet (26 patients) for hemostasis. Myomectomy was performed after either the perivascular injection of 20 U of vasopressin diluted to 20 mL with normal saline or with the use of a Foley catheter tourniquet around both uterine vessels. The efficacy of each method was measured by comparing differences in pre- and postoperative hemoglobin levels, intraoperative blood pressure, measured blood loss, need for blood transfusion, evidence of postoperative febrile morbidity, complications, and length of hospital stay. RESULTS: Vasopressin resulted in less blood loss (mean 287.3 mL [standard deviation (SD) 195] versus 512.7 mL [SD 400] for tourniquet [P = .036]). Six of 26 patients in the tourniquet group lost more than 1000 mL of blood, whereas all of the vasopressin subjects lost less than this amount (P = .023). However, there were no significant differences between the two groups in the fall in the hemoglobin level, number of blood transfusions given, intraoperative blood pressure, highest postoperative pulse and temperature, or other complications. CONCLUSION: Vasopressin prevents blood loss better than using the tourniquet during myomectomy.

Intramyometrial vasopressin as a haemostatic agent during myomectomy.

OBJECTIVE: To assess the efficacy of intramyometrial vasopressin for minimising bleeding and its sequelae at myomectomy. DESIGN: A randomised placebo controlled trial. SETTING: University Hospital of the West Indies, Kingston, Jamaica. SUBJECTS: Twenty women with symptomatic uterine fibroids scheduled for myomectomy who satisfied entry criteria: 10 randomised to the vasopressin group and 10 to the control group. INTERVENTION: Myomectomy was performed after the intramyometrial injection of either 20 units vasopressin diluted to 20 ml in normal saline or placebo (20 ml normal saline). MAIN OUTCOME MEASURES: The efficacy of vasopressin was measured by comparing pre- and post-operative haemoglobin levels and haematocrit, changes in intra-operative pulse and blood pressure, measured blood loss, need for blood transfusion and post-operative febrile morbidity in the treatment and control groups. RESULTS: The use of vasopressin resulted in median blood loss of 225 ml (range 150-400 ml) compared with 675 ml (range 500-800 ml) in the placebo group (P < 0.001). The vasopressin group had a correspondingly lower fall in haemoglobin level (median 1.7 g/dl vs 5.3 g/dl, P < 0.001) and haematocrit (median 5% vs 13%, P < 0.001) compared with the controls. Fifty percent of the placebo group had blood transfusions compared with none in the vasopressin group (P = 0.03). There were no significant differences between the groups in intra-operative pulse and blood pressure or post-operative white blood cell counts or temperature. CONCLUSION: The results indicate that vasopressin is effective in preventing blood loss and reducing the need for blood transfusion during myomectomy.

Preeclampsia in diabetic pregnancies.

Diabetic pregnancies complicated by preeclampsia are of concern because of poor perinatal outcome. However, with improved maternal and fetal surveillance the impact of preeclampsia in diabetic pregnancies is declining. This prospective controlled study compared the incidence of preeclampsia and maternal-fetal outcome in 334 diabetic pregnancies and 16,534 nondiabetic pregnancies. The incidence of preeclampsia was 9.9% (33/334) in diabetic pregnancies compared with 4.3% (716/16,534) in nondiabetic controls. The incidence of preeclampsia rose with increasing severity of diabetes by White classification, but was still 8.9% after exclusion of diabetic patients with nephropathy or chronic hypertension. The perinatal mortality rate per 1000 births was 60 for preeclamptic diabetic patients compared with 3.3 for normotensive diabetic patients. Parity, maternal age, and blood glucose control were similar in preeclamptic diabetic patients compared with normotensive diabetic patients. We conclude that preeclampsia is twice as common in diabetic pregnancies compared with normal controls.

World health: grappling with big-city problems.

London's big-city health problems are shared by 26 other cities of similar size throughout the world. By the year 2000 there will be many more of them. Miles Hardie, director-general of the International Hospital Federation, reflects on a recent UNFPA conference.
