Vasopressin reduces blood loss during myomectomy

Authors of 3 small, randomized clinical trials in nonpregnant women have reported that the intramyometrial injection of dilute vasopressin reduces blood loss during myomectomy surgery.²⁻⁴ The vasopressin doses in the 3 trials ranged from 5 U of vasopressin in 100 mL of saline to 20 U of vasopressin in 20 mL of saline. A Cochrane meta-analyis of the 3 studies concluded that, at myomectomy, the intramyometrial injection of dilute vasopressin was associated with a significant reduction in blood loss compared with placebo (246 mL vs 483 mL, respectively).¹³

There are great similarities between myomectomy in the nonpregnant and pregnant uterus. Given the clinical trials data that support the use of vasopressin to reduce blood loss during myomectomy in the nonpregnant uterus, it is likely that vasopressin also would reduce blood loss during myomectomy performed at the time of a cesarean delivery.

At cesarean delivery, elective myomectomy of intramural fibroids is generally not recommended because of the risk of massive blood loss. Clinicians often remove large pedunculated fibroids because this surgery does not usually cause massive bleeding. However, on occasion it may be necessary to perform a myomectomy on intramural myoma(s) in order to close a hysterotomy incision.

For myomectomy surgery performed at the time of cesarean delivery, many techniques have been utilized to reduce blood loss, including:

intravenous oxytocin infusion^14,15
injection of oxytocin into the myoma pseudocapsule¹⁵
electrosurgery¹⁶⁻¹⁸
argon beam coagulator¹⁹
uterine tourniquet²⁰
premyomectomy placement of a uterine U stitch²¹ or purse string suture²²
O’Leary sutures^23,24
temporary balloon occlusion of pelvic arteries²⁵
vasopressin injection.²⁶

Given the widespread use of vasopressin injection in gynecologic surgery to reduce blood loss at myomectomy, obstetricians should consider using vasopressin in their cesarean myomectomy surgery.

Use of vasopressin during cesarean delivery for placenta previa may reduce blood loss

Women with a complete placenta previa require a cesarean delivery to safely birth their baby. Cesarean deliveries performed for this indication are associated with an increased risk of hemorrhage. In one case series of 59 patients with placenta previa undergoing cesarean delivery, 4 U of vasopressin diluted in 20 mL of saline was injected into the placental implantation site to reduce blood loss. Among the patients receiving vasopressin in- jection, the blood loss was 1,149 mL. Among 50 women with placenta previa who did not receive vasopressin injection, the blood loss was 1,634 mL.²⁷

Obstetric surgery and vasopressin: The time has come

As obstetricians and gynecologists we constantly strive to improve the effectiveness of our surgical procedures and reduce adverse outcomes, including infection and blood loss. The use of vasopressin is widely accepted in gynecologic surgery as an adjuvant that reduces blood loss. The time has come to expand the use of vasopressin in difficult obstetric surgery.
