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 deathsabruptio 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
hemorrhageincludes 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 coagulationplacental 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); contributorstrauma 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 shockaltered mental status, tachycardia, orthostatic hypotension, oliguria,
or tachypnea; late shockmultiple organ-system failure; can be irreversible
|
| Treatment: goalsmaintain 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; management1000-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 atonyfirm bimanual
compression; oxytocin infusion (40 units in 1 L of 5% dextrose in lactated Ringers 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; OLeary 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)
patients weight in kg x 10; for massive blood replacement1 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; speakers 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; dictationdelayed dictation or suspicion that medical record altered fertile field
for plaintiffs attorney; American College of Obstetricians and Gynecologists (ACOG) educational/technical
bulletinspowerful tool in defending care; speaker recommends ACOGs 2006 Compendium of Selected
Publications; dissatisfied or noncompliant patientsbe 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 dont 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 laymans 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
|
