Match each classic peripartum clinical scenario presenting with acute maternal hemodynamic compromise to its corresponding primary underlying hemodynamic profile.
- A multiparous patient in active labor who suddenly develops profound dyspnea, hypotension, and cyanosis, rapidly followed by fetal bradycardia and oozing from intravenous puncture sites.Acute pulmonary hypertension leading to initial right ventricular failure, elevated central venous pressure, and early normal-to-low pulmonary capillary wedge pressure.
- A patient presenting at 4 weeks postpartum with progressive orthopnea, nocturnal cough, and new-onset lower extremity edema following an uncomplicated pregnancy and delivery.Primary left ventricular systolic dysfunction resulting in elevated pulmonary capillary wedge pressure, decreased cardiac index, and increased systemic vascular resistance.
- A nulliparous patient with prolonged rupture of membranes who develops maternal fever, purulent cervical discharge, and subsequent hypotension refractory to intravenous fluid resuscitation.Profoundly decreased systemic vascular resistance, compensatory elevated cardiac output, and widened pulse pressure characteristic of distributive shock.
- A multiparous patient 2 hours after a complicated operative vaginal delivery who exhibits progressive tachycardia and hypotension despite a firmly contracted uterus and no visible external vaginal bleeding.Markedly decreased central venous pressure and pulmonary capillary wedge pressure with a severely depressed cardiac output and compensatory high systemic vascular resistance.
Cevap
Amniotic fluid embolism matches with acute right ventricular failure (early normal-to-low PCWP). Peripartum cardiomyopathy matches with elevated PCWP and decreased cardiac index. Septic shock matches with decreased systemic vascular resistance. Hypovolemic shock matches with markedly decreased central venous and pulmonary capillary wedge pressures.
Each peripartum complication presents with a unique pattern of shock that can be distinguished by hemodynamic parameters. Amniotic fluid embolism initially causes right heart failure (high CVP, low PCWP). Peripartum cardiomyopathy causes cardiogenic shock/left heart failure (high PCWP, low CO). Chorioamnionitis progressing to sepsis causes distributive shock (low SVR, high CO). Occult hematomas cause hypovolemic shock (low CVP/PCWP, high SVR).
