Key points for anesthetic and hemodynamic management during labor and delivery in dilated cardiomyopathy

Key points for anesthetic and hemodynamic management during labor and delivery in dilated cardiomyopathy
Hemodynamic goals Avoid Monitor Intervention
Sinus rhythm Electromagnetic interference due to electrocautery in patients with an ICD 5-lead ECG Management of an ICD:
  • Keep anti-tachyarrhythmia function of ICD active in labor
  • Assure preparations to suspend this function in the event of emergent cesarean delivery
Normal heart rate Bradycardia

5-lead ECG

Pulse oximetry with visible waveform
Treat bradycardia with ephedrine; gycopyrrolate if necessary.
Maintain contractility Myocardial depression Hemoynamics Treat low cardiac output syndrome with milrinone or dobutamine; epinephrine or norepinephrine may be added if necessary to treat hypotension.
Maintain afterload Hypertension Intra-arterial blood pressure Prevent pain-induced hypertension by minimizing or eliminating labor pain with effective analgesia.
Hypotension Intra-arterial blood pressure Treat hypotension with ephedrine or norepinephrine.
Adequate preload Hypervolemia Clinical course and oxygenation. Development of pulmonary edema (may present as acute coughing and hypoxemia in the awake patient). Management of pulmonary edema:
  • Treat hypoxemia related to pulmonary edema with 100% oxygen, PEEP, and, if necessary, intubation and controlled ventilation
Hypovolemia Hemodynamics Allow oral intake and administer maintenance IV fluids, if necessary, to maintain adequate preload.
Minimize pulmonary vascular resistance (optimize oxygenation and ventilation) Hypoxemia or hypercarbia Pulse oximetry with visible waveform Minimize risk of hypoxemia and hypercarbia by:
  • Administering supplemental oxygen throughout labor and delivery
  • Avoiding oversedation
  • Ensuring well-controlled ventilation, if intubated
ICD: implantable cardioverter-defibrillator device; ECG: electrocardiogram; PEEP: positive end-expiratory pressure; IV: intravenous.
