Hemodynamic Responses to Etomidate in Pediatric Patients with Congenital Cardiac Shunt Lesions
چکیده انگلیسی

ObjectiveThe authors investigated the effects of intravenous etomidate on hemodynamics in children with congenital cardiac shunts.DesignProspective observational study.SettingCatheterization laboratory in tertiary referral cardiac center.ParticipantsThirty children with congenital cardiac shunt lesions.InterventionsFifteen children having congenital right to left shunts (group A) and 15 children with left to right shunts (group B) were studied. Systemic mean arterial pressure (SMAP), mean pulmonary artery pressures (MPAP), right atrial pressures (RAP), and pulmonary artery wedge pressure (PAWP) were recorded. Systemic vascular resistance index (SVRI), pulmonary vascular resistance index (PVRI), and pulmonary-to-systemic blood flow ratio (Qp/Qs) were calculated on room air at baseline and following a single dose of 0.3 mg/kg of etomidate.Measurements and Main ResultsHeart rate (HR), SMAP, RAP, systemic blood flow (Qs), Qp/Qs, and SVRI did not show any significant change; whereas systemic arterial saturation increased from 77.3% to 79.3%, which was statistically but not clinically significant in the authors' opinion following etomidate in group A. No significant differences in HR, SMAP, MPAP, PAWP, PVRI, SVRI, Qs, pulmonary blood flow (Qp), and Qp/Qs ratio were seen; whereas RAP, systemic, and pulmonary artery saturation decreased in group B after etomidate. Although statistically significant, the decreases were not clinically significant.ConclusionEtomidate at 0.3 mg/kg produces very minimal changes in hemodynamic parameters and shunt fraction in children with congenital shunt lesions.
