Chapter 21: Sudden Pregnancy Complications Nursing Care

A critical area of concern is bleeding during pregnancy, which is always considered potentially serious, as external blood loss may significantly underestimate internal hemorrhage, rapidly leading to hypovolemic shock where fetal circulation can be severely compromised once 25% of maternal blood volume is lost. Causes of bleeding vary by gestation: early pregnancy losses, often termed spontaneous miscarriages (occurring before 20 weeks), frequently result from abnormal fetal development or chromosomal aberrations, while ectopic pregnancy involves implantation outside the uterine cavity, classically causing sharp, unilateral abdominal pain and requiring immediate surgical or medical intervention (methotrexate). Gestational trophoblastic disease (hydatidiform mole), characterized by the abnormal overgrowth of trophoblast cells and excessively high levels of human chorionic gonadotropin (hCG), also requires evacuation and strict follow-up due to the risk of malignancy. Later pregnancy bleeding often results from placenta previa (painless, low implantation) or premature separation of the placenta (abruptio placentae), which is typically painful, sudden, and can quickly lead to Disseminated Intravascular Coagulation (DIC), a severe acquired clotting disorder requiring termination of the inciting event. Management of preterm labor (before 37 weeks) focuses on using corticosteroids like betamethasone to accelerate fetal lung maturity and administering tocolytic agents such as magnesium sulfate (often for fetal neuroprotection) or terbutaline to halt contractions, though monitoring for potential adverse effects is constant. Hypertensive disorders range from gestational hypertension to preeclampsia (defined by blood pressure elevation, usually 140/90 mm Hg or higher, and proteinuria) and finally to eclampsia (seizures). Severe preeclampsia (systolic 160 mm Hg or diastolic 110 mm Hg or higher) is treated with hospitalization, antihypertensive drugs, and magnesium sulfate, the preferred anticonvulsant, with its specific antidote, calcium gluconate, kept readily available. A life-threatening variant, HELLP syndrome, involves hemolysis, elevated liver enzymes, and a low platelet count. Other complications include premature cervical dilatation, often corrected by cervical cerclage in subsequent pregnancies; disorders of amniotic fluid volume (polyhydramnios, or excess fluid, or oligohydramnios, or too little fluid); postterm pregnancy (beyond 42 weeks, associated with placental deterioration); and isoimmunization (Rh incompatibility), which is prevented in Rh-negative patients by administering RhIG. Across all these high-risk scenarios, nursing care integrates physical interventions with comprehensive emotional support to help patients and families cope with anxiety, fear, and loss.
