Antepartum Triage and Urgent Maternal Warning Signs

—

In one line

·Pregnancy reshapes how the body works, so normal changes can look like sickness, and real emergencies can hide behind normal-looking vital signs until the mother suddenly crashes.

—

Normal physiology

·Normal pregnancy makes blood clot more easily (to prevent dangerous bleeding at delivery), increases total blood volume by forty to fifty percent (so there's enough to feed both mother and baby), relaxes and widens blood vessels all over the body (which drops blood pressure by five to ten points in the second trimester), and shifts the immune system so it tolerates the baby's proteins instead of attacking them. Heart rate climbs ten to twenty beats per minute above the non-pregnant baseline. Breathing rate may tick up slightly because the growing uterus pushes the diaphragm (the breathing muscle under the lungs) up and the body needs more oxygen. These changes can look like disease in someone who isn't pregnant, so you must know the normal pregnancy baseline to spot true emergencies.

What goes wrong

·One upstream failure usually explains the entire pattern of abnormal findings you see. In preeclampsia, poor placenta blood flow at the start triggers a cascade that damages blood vessel linings everywhere, which then raises blood pressure, spills protein into urine, drops platelet counts, injures the liver and kidneys, swells the brain, and can cause seizures. In placental abruption, the placenta tears away from the uterus wall, bleeding into the muscle, which causes pain, visible bleeding, a rock-hard uterus, and fetal distress. In pulmonary embolism (a clot lodging in a lung artery), a clot (usually from a leg vein) blocks lung arteries, cutting oxygen and overloading the right side of the heart. Each downstream sign points back to the single upstream break.

Hallmark signs

·Severe headache that does not go away with acetaminophen (Tylenol)
·Vision problems (blurry vision, seeing spots or flashing lights, blind spots, bright light hurts your eyes, or complete loss of vision)
·Sharp pain in the right upper belly or just below the ribs in the middle (the epigastric area)
·Overactive reflexes when the doctor taps your knee or ankle, sometimes with rhythmic twitching (clonus) of the foot
·Sudden trouble breathing or chest pain that feels different from the normal shortness of breath in late pregnancy
·Blood pressure of 140 over 90 or higher that starts after 20 weeks of pregnancy
·Protein in the urine (300 milligrams or more in 24 hours, or a urine protein-to-creatinine ratio of 0.3 or higher)
·Swelling, especially sudden puffiness in the face or hands, or gaining more than 4 to 5 pounds in one week

Red flags · escalate now

·Blood pressure of 160 over 110 or higher that stays high for 15 minutes or more—the brain can have a stroke (bleeding or blood vessel rupture), so blood pressure medicine (labetalol or hydralazine IV, or nifedipine by mouth) must be given within 30 to 60 minutes
·A seizure (eclampsia) that happens for the first time during pregnancy or in the first few days after delivery—this means the brain is severely swollen; the airway must be protected (turn her on her side so she does not choke), magnesium sulfate given through the IV to stop more seizures, and the baby delivered as soon as it is safe
·Platelet count below 100,000 per microliter or platelets dropping fast—this means the blood cannot clot properly and dangerous bleeding could happen during delivery or surgery
·Liver enzyme levels (AST or ALT) more than twice the normal limit, especially with sharp right upper belly pain—the liver could rupture (liver a pooled collection of blood (hematoma) rupture) and cause life-threatening internal bleeding into the belly
·Fluid in the lungs (pulmonary swelling (edema)) or oxygen level below 95 percent on room air—the heart and lungs are failing and intensive care with oxygen, diuretics, or even a breathing tube is needed immediately
·Kidney function worsening with creatinine above 1.1 milligrams per deciliter or doubling from the woman's usual level—the kidneys are shutting down and dialysis may be needed if the creatinine keeps climbing

—

Workup

·Complete blood count (CBC) with platelet count
·Comprehensive metabolic panel (CMP) including serum creatinine, blood urea nitrogen (BUN), and electrolytes
·Liver function tests: aspartate aminotransferase (AST) and alanine aminotransferase (ALT)
·Lactate dehydrogenase (LDH)
·Urine protein-to-creatinine ratio in a spot urine sample, or 24-hour urine protein collection
·Serum uric acid
·Obstetric ultrasound with Doppler assessment of umbilical artery flow and continuous fetal heart rate monitoring (cardiotocography)
·Repeat platelet count, AST, ALT, LDH, and creatinine every 12 to 24 hours if preeclampsia with severe features is diagnosed

Treatment

·IV labetalol 20 mg over 2 minutes, then double the dose every 10 minutes (20 mg, then 40 mg, then 80 mg, max total 300 mg); OR IV hydralazine 5 to 10 mg every 20 minutes; OR oral immediate-release nifedipine 10 to 20 mg every 20 minutes until blood pressure is sustained below 160 systolic and below 110 diastolic within 60 minutes
·IV magnesium sulfate: 4 to 6 grams loading dose given over 15 to 20 minutes, followed by continuous infusion at 1 to 2 grams per hour for seizure prevention in preeclampsia with severe features, or for treatment if an eclamptic seizure occurs
·Expedited delivery by labor induction (if the cervix is favorable and the fetus is stable) or cesarean section (if cervix is unfavorable, fetus is in distress, or maternal condition is critical) after maternal stabilization with magnesium sulfate and blood pressure medication; or immediate delivery without delay if eclampsia, placental abruption, non-reassuring fetal status, or HELLP syndrome is present
·Betamethasone 12 mg intramuscular injection every 24 hours for 2 doses, OR dexamethasone 6 mg intramuscular injection every 12 hours for 4 doses, if gestational age is 24 weeks 0 days to 36 weeks 6 days and delivery is expected within the next 7 days
·Therapeutic-dose low-molecular-weight heparin (enoxaparin 1 mg per kilogram subcutaneously every 12 hours, or dalteparin 100 units per kilogram every 12 hours) if a clot in a deep leg vein (deep vein thrombosis) or pulmonary embolism (a clot lodging in a lung artery) is confirmed on imaging; OR preventive (prophylactic)-dose enoxaparin (40 mg once daily or 30 mg twice daily) if high clinical suspicion exists before imaging or if risk factors are present
·Two large-bore (18-gauge or larger) IV lines with rapid crystalloid infusion (lactated Ringer's solution or normal saline, 1 to 2 liters wide open initially), continuous fetal and maternal monitoring, type and crossmatch for 4 to 6 units of packed red blood cells, immediate obstetric and anesthesia consultation, and activation of massive transfusion protocol if placental abruption with bleeding (hemorrhage) is suspected
·Close monitoring after delivery for at least 72 hours with daily blood pressure checks, repeat labs (CBC, liver enzymes, creatinine) at 48 hours or sooner if symptoms worsen, and continued magnesium sulfate infusion for 24 hours after delivery or after the last seizure; switch to oral blood pressure medication (labetalol, nifedipine, or methyldopa) if blood pressure stays ≥140/90 mmHg, and schedule outpatient follow-up within 7 to 10 days

NCLEX trap

·Preeclampsia is new high blood pressure after 20 weeks of pregnancy PLUS evidence that organs are getting hurt. Check urine protein, complete blood count (CBC, a panel of blood cell counts — especially platelets, the tiny clotting helpers), liver enzymes (AST and ALT, markers that leak out when liver cells are damaged), creatinine (a waste product in the blood that rises when the kidneys are struggling), and neurologic symptoms like severe headache or vision changes. Blood pressure medicine prevents stroke but does not fix the underlying disease — only delivering the baby and placenta cures preeclampsia.
·A pregnant patient with preeclampsia can appear stable and then suddenly develop eclampsia (seizures caused by preeclampsia), placental abruption (the placenta tears away from the uterus early, cutting off the baby's oxygen), or pulmonary edema (fluid flooding the lungs) (fluid backs up into the lungs, making it hard to breathe) within hours. Warning signs such as severe headache, vision changes, or pain under the right ribs require immediate admission, continuous monitoring, and urgent delivery planning. Never discharge.
·Lowering blood pressure with labetalol (a beta blocker, a medicine that slows the heart and relaxes blood vessels) or hydralazine (a vasodilator, a medicine that opens up tight blood vessels) prevents bleeding-driven (hemorrhagic) stroke (bleeding in the brain from burst vessels), but it does not stop ongoing organ damage to the kidneys, liver, and placenta. You must also give magnesium sulfate to prevent eclamptic seizures by raising the seizure threshold (the point at which the brain fires uncontrollably) and prepare for delivery within 24 to 48 hours in severe cases.
·New high blood pressure after 20 weeks plus proteinuria (protein in urine, measured as ≥300 mg in 24 hours or a urine protein-to-creatinine ratio ≥0.3) plus a low platelet count (thrombocytopenia) (platelet count less than 100,000 per microliter — the tiny clotting cells are being used up) equals preeclampsia with severe features, not gestational high blood pressure (hypertension). Gestational high blood pressure is elevated blood pressure alone without proteinuria or organ damage. Preeclampsia with severe features requires magnesium sulfate for seizure prevention (prophylaxis) (prevention) and expedited delivery.
·Preeclampsia harms both the pregnant person and the fetus. First assess maternal blood pressure, urine protein, complete blood count (especially platelets), liver enzymes (AST and ALT), creatinine, and neurologic status (headache, visual changes, overactive reflexes (hyperreflexia) — overactive reflexes that signal brain irritability). Then monitor fetal well-being. Maternal organ damage determines severity and delivery timing because the pregnant person's survival protects the baby.
·Right upper quadrant or epigastric (upper middle abdomen) pain in a pregnant person with high blood pressure (hypertension) is HELLP syndrome (Hemolysis — red blood cells breaking apart, Elevated Liver enzymes, Low Platelets) — a life-threatening preeclampsia variant — until proven otherwise. Immediately check AST, ALT, LDH (lactate dehydrogenase, a marker of cell breakdown released when cells die), platelets, and peripheral blood smear (a microscope slide of blood to look for broken red blood cells). This requires urgent delivery.
