AN OUNCE OF PREVENTION

Highlights from the 61st Obstetrical and Gynecological Assembly of Southern California

OBSTETRIC HEMORRHAGE —James G. Quirk, MD, Professor and Chairman, Department of Obstetrics, Gynecology, and Reproductive Medicine, State University of New York at Stonybrook
General considerations: hemorrhage leading cause of maternal mortality in United States; speaker opines increasing frequency of cesarean delivery will make obstetric hemorrhage more significant issue in future; causes of pregnancy-related hemorrhagic deaths—abruptio placentae, uterine rupture, uterine atony, coagulation disorder, placenta previa, placenta accreta, and retained placenta; significant contributors— inadequate resources and personnel, eg, home delivery, failure to prepare for obstetric hemorrhage, no intravenous (IV) site, delay in recognition of hemorrhage, delay in treatment of hemorrhage, treatment failures; necessity of blood transfusion in para 0 patient as frequent as para 5 patient (atony in higher parities)
Obstetric hemorrhage: 2% to 3% of patients having prolonged labor, operative vaginal delivery, or cesarean delivery receive blood transfusions; definition—>500 mL blood loss during vaginal delivery and 1000 mL during cesarean delivery; occurs in at least 30% of vaginal deliveries, 20% to 25% of cesarean deliveries; 28% of patients undergoing cesarean delivery plus total hysterectomy have blood loss of 500 to 1000 mL, 28% have blood loss of 1000 to 1500 mL, and 28% exceed 1500 mL; incidence of obstetric hemorrhage—includes disorders of delivery in puerperium; cesarean delivery 1 in 6, ruptured uterus 1 in 11,000; uterine rupture occurs in >50% of women with surgically unscarred uteruses; obstetric lacerations occur in 1 of 8 women; pregnant woman can lose 40% of blood volume, compared to 25% in nonpregnant patient, before becoming hemodynamically unstable
Contributing factors: conditions predisposing to impaired coagulation—placental abruption, prolonged retention of dead fetus, and amniotic fluid embolism; can lead to disseminated intravascular coagulation (DIC), profound hypoxia, and multiple organ-system failure (recalcitrant and associated with maternal death); contributors—trauma during labor or delivery, small maternal blood volume (small women, women with chronic cardiovascular disease, hypertensive women, or those who bleed earlier in pregnancy), and women with abnormal placental implantation or development, eg, ectopic, placental abruption
Clinical features of shock: early shock—altered mental status, tachycardia, orthostatic hypotension, oliguria, or tachypnea; late shock—multiple organ-system failure; can be irreversible
Treatment: goals—maintain systolic blood pressure >90 mm/Hg, urine output >0.5 mL/kg per hour (30- 35 mL/hr), and normal mental status; eliminate source of hemorrhage; avoid overzealous volume replacement that may contribute to pulmonary edema; management—1000-mL blood loss represents 15% of volume, 1001 mL to 1500 mL 15% to 25%; begin fluid resuscitation with crystalloid solution, but be prepared to move quickly to transfusion; under bright lights, examine patient for source of bleeding; rule out atony, lacerations, and retained placenta; treatment options for uterine atony—firm bimanual compression; oxytocin infusion (40 units in 1 L of 5% dextrose in lactated Ringer’s solution [D5LR]); intramuscular (IM) injections of carboprost (Hemabate; can be repeated); methylergonovine (Methergine) if patient not hypertensive; bilateral uterine artery ligation; internal iliac (hypogastric) artery ligation; hysterectomy; speaker does not consider hypogastric artery ligation first-line therapy; consult with interventional radiologist; B-Lynch (brace suture) innovative suture technique; O’Leary suture decreases pulse pressure and blood loss, but does not eliminate need for oxytocic agents
Management of hypovolemic shock: insert at least 2 large-bore IV catheters; alert blood bank; place patient in Trendelenburg position; call for extra staff, including consultant anesthesiologist; rapidly infuse D5LR solution while waiting for blood products; formula for transfusion of packed red blood cells (RBCs)— patient’s weight in kg x 10; for massive blood replacement—1 unit of fresh frozen plasma after every 3rd unit of packed RBCs; infuse only normal saline with transfusion (hemolysis with D5W can lead to renal failure); use blood products within 4 hr; infuse at 100 mL/min; speaker opines transfusion risk overstated when put in context of life-threatening hemorrhage
Improving quality of care: important to have team of well-organized skilled providers and system in place in labor and delivery units; speaker’s institution holds simulated drills (code Noelle); caveats— obstetric staff considering transfusing pregnant patient should notify anesthesia department; blood loss during delivery almost always underestimated; hypotension in pregnant patient implies estimated blood loss of >2000 mL; surgical management must be very aggressive; control source of hemorrhage; utilize additional resources, eg, gynecologic surgeon; identify high-risk patients; maternal hemorrhage number one cause of maternal death in New York; identify high-risk patient to prevent severe complications; early intervention crucial for low-risk patient starting to bleed
CHICKEN SOUP FOR THE DEFENDANT PHYSICIAN Richard M. Soderstrom, MD, Professor Emeritus, University of Washington School of Medicine, Seattle
Standard of care: what reasonable prudent physician would foresee and would do in light of this foresight under like circumstances (Harper and James, Law of Torts); whether requirement to have foresight too rigid currently in question; whether negligence occurred and whether it made difference important elements in determining medical malpractice
Risk management: documentation— important to document all advice given to patient; contact same-day surgical patients by telephone following day and document conversation; when complications managed by second facility, attempt to communicate with provider managing complication; standard of care— applies equally between specialties; general surgeons performing laparoscopy must adhere to same standards as gynecologists; dictation—delayed dictation or suspicion that medical record altered fertile field for plaintiff’s attorney; American College of Obstetricians and Gynecologists (ACOG) educational/technical bulletins—powerful tool in defending care; speaker recommends ACOG’s 2006 Compendium of Selected Publications; dissatisfied or noncompliant patients—be aware of and pay special attention to
Surviving lawsuit: when served with formal declaration and summons, notify insurance carrier first, not attorney; records from insurance carrier discoverable in some states; determine best way to communicate with insurance carrier; do not alter or add to medical record; with disclaimer, provider may be allowed to read from medical record if handwriting illegible; review medical record and become familiar with facts before deposition; be readily available to take calls from insurance representative or attorney (instruct office staff to inform you when they call); become knowledgeable about subject matter of lawsuit; educate attorney on specific matter pertaining to lawsuit and assist in finding qualified expert witness; settlement may be practical, does not imply malpractice or negligence
Preparing for deposition: review interrogatory answers; ensure medical records properly assembled; construct story board of events pertaining to lawsuit; consider having visuals (eg, laparoscope, bipolar forceps, trocar, at deposition); prepare updated curriculum vitae and summary of continuing medical education credits for last 3 yr; find literature supporting your management, particularly literature around time of event; dress professionally; exercise courtesy and good manners; make deposition practice run for how you will conduct self at time of trial; speak up and do not use gestures; tell truth; review transcript of deposition; understand question before answering; pause before you answer; answer only question, do not volunteer information; do not guess, say “I don’t know or recall”; do not use hearsay information; do not hide facts; if your attorney objects, stop talking; without objection, you are bound to answer; be factual and straightforward; check facts against record before answering; do not look for traps, leave that to your attorney; never argue or become hostile and angry; testify to your best memory; give explanations in layman’s terms; discuss with your attorney whether educating opposing attorney beneficial
Miscellaneous issues: endoscopy leads in surgical litigation (more than all surgical specialties combined); make telephone “rounds” with patients undergoing outpatient procedures; poor postoperative progress mandates office visit; emergency department providers should understand known risks of same-day surgical procedures; chances of being sued high, but chances of prevailing good

Educational Objectives

The goal of this program is to educate the listener about the management of obstetric hemorrhage and the fundamentals of handling a medical malpractice lawsuit. After hearing and assimilating this program, the clinician will be better able to:
1. List the causes of and significant contributors to pregnancy-related hemorrhagic death.
2. Discuss the guidelines for component therapy in managing obstetric hemorrhage.
3. Summarize the need for having a well-organized system in place in labor and delivery units.
4. Discuss steps that can be taken to reduce the risk for a medical malpractice lawsuit.
5. Assist in the defense of a medical malpractice lawsuit.
