TRAUMA Accounts for an estimated 20% of cases of PPH Blood loss due to genital tract trauma • Lacerations and hematomas of vagina, perineum or cervix • Laceration at CS, extension of incision • Uterine rupture • Uterine inversion

Retroperitoneum The most common childbirth-related causes are (1) laceration of a uterine artery during hysterotomy or from uterine rupture and (2) extension of a paravaginal hematoma. Other causes include trauma, anticoagulation, ruptured ectopic pregnancy, and rupture of an aneurysm in the abdominopelvic vasculature.

The clinical manifestations of puerperal hematomas vary depending upon the location of the hematoma. pain and mass effects

Vulvar hematomas usually present with rapid development of a severely painful, tense, compressible mass covered by skin with purplish discoloration . A vulvar hematoma may be an extension of a vaginal hematoma that has dissected through loose subcutaneous tissue into the vulva.

Vaginal hematomas often present with rectal pressure; however, hemodynamic instability due to bleeding into the ischiorectal fossa and paravaginal space may be the first indication of a vaginal hematoma, and can result in hypovolemic shock

Patients with a retroperitoneal hematoma usually do not present with pain unless the hematoma is associated with trauma. Palpation of an abdominal mass or fever can also be signs of a retroperitoneal hematoma.

To identify nonpalpable hematomas in puerperal women with pain or pressure suggestive of a hematoma, particularly retroperitoneal hematomas

sonography for initial evaluation computed tomography if there is a suspicion for a retroperitoneal hematoma Arteriovenous malformations have been reported in association with hematoma formation. The use of intravenous contrast at the time of computed tomography can aid in diagnosis in these cases

. Magnetic resonance imaging is more time- consuming, expensive, and less readily available than ultrasound or CT.

Hemodynamically stable patients almost always have venous bleeding place a large-bore intravenous line to administer crystalloid complete blood count, fibrinogen level, prothrombin time, and partial thromboplastin time to determine baseline levels and whether a bleeding diathesis is present.

The use of pudendal block is generally not practical, given the physical difficulty of getting around the hematoma to appropriately administer the block.

Consultation with an interventional radiologist is another option, especially for retroperitoneal hematomas. Percutaneous transcatheter interventional procedures (ie, angiographic embolization) have been used in the management of vulvovaginal hematomas and for retroperitoneal bleeding as a first-line therapy

We generally administer antibiotics (for surgical site prophylaxis) to patients undergoing surgical intervention. Generally, endocarditis prophylaxis is not indicated for minor vaginal or vulvar procedures in the absence of clinical infection

managment (1) conservative management with observation and supportive care, (2) surgical intervention, (3) selective arterial embolization.

Monitoring should be undertaken in an acute care area, such as an obstetrical unit recovery area where vital signs (including urinary output) can be monitored at least hourly It is important to keep in mind the usual hemodynamic changes that occur in the postpartum period. Patients can experience significant blood loss without changes in blood pressure. Therefore, signs of decreased end-organ perfusion (such as lethargy and decreased urinary output

One group suggested surgical intervention when the patient had significant pain or expansion of the hematoma, or if the hematoma was >5 cm or had estimated volume >200 mL

prompt surgical intervention is necessary if there is expansion of the hematoma on physical examination or imaging studies or a falling hematocrit, as persistent hemorrhage can lead to hemodynamic instability or put the tissue at risk of necrosis

As with vulvar hematomas, vaginal hematomas larger than approximately 4 cm may need to be evacuated . Vaginal packing with gauze or a balloon (eg, Bakri, Sengstaken-Blakemore, balloon rectal tube) [ for 12 to 24 hours may aid in tamponade

A Foley catheter is necessary to drain the bladder in the presence of a vaginal pack or significant edema.

POSTOPERATIVE CARE  — Perineal hygiene with Sitz baths and gentle cleansing with saline rinse are encouraged after vulvar surgery. Adequate analgesia should be prescribed. We suggest pelvic rest (no vaginal coitus or placement of tampons or vaginal medications) for four to six weeks, depending upon the extent of the injury, to avoid disruption of healing tissues.

Pressure necrosis of the swollen external genitalia may be prevented by having the patient rest primarily on her side or back. At discharge, patients should be counseled to call their provider promptly if they develop fever, new or worsening pain, or bleeding.

An upright abdominal film looking for free air under the diaphragm is indicated if there is suspicion that a vaginal laceration has extended into the peritoneal cavity

conclusion Regarding management of hematomas, if possible, vulvar hematomas are managed conservatively with ice, analgesia, and pelvic rest. A Foley catheter is recommended if the hematoma is large since it often interferes with urination Expansion of a vulvar or vaginal hematoma or a falling hematocrit are indications for prompt surgical intervention
