Complications Antepartum Intrapartum Postpartum Maternal Mortality According to official US vital statistics, the risk of death from complications of pregnancy decreased approximately 99% during the 20th century. However, this progress halted in 1982, and since then, there has been no improvement in the maternal mortality ratio for the US. In the most recent global figures from the World Health Organization, the US ranked 20th in maternal mortality, behind most countries of Western Europe as well as Canada, Australia, Israel, and Singapore. September 2001, the first National Summit on Safe Motherhood Maternal Mortality Many consider a maternal death to be a sentinel event, reflecting a breakdown in the health care system in its broadest sense. Mortality caused by pregnancy and its complications remains an important issue for…the health care system, and as a public health indicator. There continues to be striking racial disparity in maternal mortality.

No plane of separation Risk of hysterectomy at time of birth Prior C/S increases risk of accreta • The more C/S the higher the risk Bleeding - Abruption Also called Abruptio Placenta Bleeding - Abruption Premature separation of the normally implanted placenta Serious hemorrhage in the late second and the third trimesters Bleeding may be Concealed Obvious Both Bleeding - Abruption

extravasating blood) Bleeding - Abruption Defining Characteristics Bleeding (maybe concealed) Pain Colicky uterine contractions Violent/decreased/absent FM FHT changes • • • • Tachycardia Loss of

Nifedipine (SL, PO) Hourly assessments for magnesium toxicity and efficacy of medication Ca++ channel blocker Indomethacin (PO, PR) Prostaglandin synthetase inhibitor May cause premature closure of ductus and oligohydramnios Diabetes in Pregnancy Pre-Gestational Diabetes Type 1 – usually insulin dependent Type 2 – may or may not require insulin Gestational Diabetes Onset after 20 weeks of pregnancy Resolves by six weeks postpartum • Emphasize f/u due to lifetime risk of DM Usually controlled by • Diet • Exercise • Blood glucose monitoring Diabetes in Pregnancy Universal screen at 28

insulin resistance during pregnancy If pancreas cannot produce more insulin to compensate for resistance ’d circulating glucose Crosses placenta ’d fetal insulin Insulin acts as growth hormone Macrosomia Diabetes in Pregnancy Fat deposition is around the shoulder girdle risk of shoulder dystocia Hyperglycemia ’s risk of other congenital anomalies risk of neonatal hypoglycemia Cord cut glucose levels fall rapidly Neonate still has circulating insulin Diabetes in Pregnancy Tight glycemic control can reduce the risk of pregnancy complications Usually aim for Fasting ≤ 95 2 hour

Precautions Hourly vital signs Prepare for delivery Hypertensive Disorders of Pregnancy If progresses to eclampsia Magnesium Sulfate (MgSO4) Protect airway Intrauterine stabilization of fetus Protect from excess stimuli May proceed to cesarean when stable Likely transfer to intensive care unit for postpartum stabilization Hypertensive Disorders of Pregnancy HELLP syndrome Hemolysis, Elevated Liver Enzymes, Low Platelets Atypical Pre-eclampsia presentation May be complicated further by Disseminated Intravascular Coagulation Cesarean Section Problem with the 3 P’s of labor Powers • Inadequate, too strong, uncoordinated Passenger • Not tolerating labor, malpresentation, size or congenital anomalies Passage • Mismatch with passenger, unsafe for mother to labor C/S in the absence of a medical indication Current C/S rate ~ 30% anecdotal reports approaching 50% Cesarean Section Types Low Transverse • Horizontal uterine incision • Also called low cervical, low segment • Most common, VBAC OK Classical • Vertical incision on uterus • Uncommon, VBAC contraindicated • Emergency, preterm, malpresentation Cesarean Section Planned Unexpected, but not emergent Labor contraindicated Maternal choice (highly controversial) Problem with 3 P’s, mother & baby stable Urgent Need to proceed to protect life or health “Decision to incision” time <30 minutes • With suspected uterine rupture <18 minutes Nursing care depends on circumstances Cesarean Section Support person present in the OR Remind not to touch sterile areas Provide a stool to sit on behind drape Keep on eye on them Anesthesiologist/Nurse- Anesthetist Excellent at communicating with client Labor nurse usually becomes circulating nurse in the OR Cesarean Section Post-operative recovery usually on L&D in special PACU area if both mother & newborn stable • Kept together in PACU area • Take care to promote thermoregulation Assist to breastfeed in PACU if able All postpartum assessments All post-operative assessments Client and/or support person may need to verbalize about c/s Amniotic Fluid Embolism Amniotic Fluid enters systemic circulation Unexplained Hypertonic contractions Sudden onset of Respiratory distress Bleeding/oozing (DIC) Cyanosis Pain Shock coma Amniotic Fluid Embolism Life threatening emergency ABCs Blood products Intensive care, central monitoring Often fatal to mother and baby I have only seen this once >40 units of PRBCs and FFPs Near death experience reported Shoulder Dystocia Anterior shoulder stuck behind maternal symphysis pubis Unpredictable Increased risk with Prolonged labor Macrosomic fetus Poorly controlled maternal diabetes Shoulder Dystocia Defining Characteristics Unexpectedly slow crowning Turtle sign with birth of fetal head • No restitution or external rotation Have 4 – 6 minutes to get the baby out before brain damage ensues Shoulder Dystocia drills Shoulder Dystocia Nursing Interventions Note time of birth of the head Note all interventions used to relieve Note which fetal shoulder impacted Call for help Provide suprapubic pressure when asked • NOT fundal pressure Sharply flex and abduct maternal legs onto abdomen (McRoberts maneuver) Anticipate neonatal resuscitation and maternal postpartum hemorrhage Postpartum Hemorrhage Any blood loss significant enough to cause signs and symptoms Traditionally >500 cc for vaginal birth and >1000 cc for cesarean section May be resolved surgically if Laceration repair Retained placenta (late hemorrhage) Placenta accreta Thrombophlebitis Pregnancy is a prime example of Virchow's triad of increased risk for VTE venous wall damage/irritation change in flow • • • • • Immobility Local pressure Varicose veins Venous obstruction Hydration, hypovolemia blood hypercoagulability • adaptations for hemostatsis in labor Thrombophlebitis Defining Characteristics Pain in area of clot • if peripheral, +/- erythema • If peripheral, +/- edema • If peripheral, +/- cord palpable • Do NOT massage • If peripheral, +/- homan’s sign Possibly fever, chills Thrombophlebitis Nursing Interventions Moist heat as ordered Pain assessment/management Observe for s/sx of PE Administer anticoagulant therapy as ordered – usually Lovenox/heparin • Large molecule, does not cross placenta and not secreted in breast milk • Coumadin contraindicated in pregnancy Endometritis Postpartum infection of the endometrium Predisposing factors Prolonged labor Prolonged rupture of membranes Cesarean birth Trauma Retained products of conception Endometritis May spread and become a systemic infection leading to sepsis A major cause of morbidity and mortality Endometritis Defining Characteristics Temperature >100.4 Alteration in VS Fundal tenderness Foul smelling vaginal discharge Rigors, Malaise + blood cultures Endometritis Administer antibiotics as ordered May be on triple antibiotics Promote adequate hydration Promote adequate nutrition Protect mother-baby bonding and interaction Baby may also have infection Promote activity as appropriate REMEMBER! Despite this depressing and frightening lecture The overwhelming majority of births are straightforward The human race has been around a long time . . . Birth works and babies come out or we wouldn’t be here today!
