Context: Cardiac surgery patients undergoing coronary artery bypass grafting with cardiopulmonary bypass. Objective: Evaluate the effect of adding intrathecal sufentanit to general anesthesia on hemodynamics. Design: Prospective, randomized, not blinded study, after approval by local ethics in Research Committee. Setting: Monocentric study performed at Dante Pazzanese Institute of Cardiology, Sao Paulo, Brazil. Patients: 40 consenting patients undergoing elective coronary artery bypass, both genders. Exclusion criteria: Chronic kidney disease; emergency procedures; reoperations; contraindication to spinal block; left ventricular ejection fraction less than 40%; body mass index above 32 kg/m(2) and use of nitroglycerin. Interventions: Patients were randomly assigned to receive intrathecal sufentanil 1 mu g/kg or not. Anesthesia induced and maintained with sevoflurane and continuous infusion of remifentanil. Main outcome measures: Hemodynamic variables, blood levels of cardiac troponin I, B-type natriuretic peptide, interteukin-6 and tumor necrosis factor alfa during and after surgery. Results: Patients in sufentanit group required less inotropic support with dopamine when compared to control group (9.5% vs 58%, p = 0.001) and less increases in remifentanil doses (62% vs 100%, p= 0.004). Hemodynamic data at eight different time points and biochemical data showed no differences between groups. Conclusions: Patients receiving intrathecal sufentanit have more hemodynamical stability, as suggested by the reduced inotropic support and fewer adjustments in intravenous opioid doses.

Abstract

Objective: Evaluate the effect of adding intrathecal sufentanit to general anesthesia on hemodynamics. Design: Prospective, randomized, not blinded study, after approval by local ethics in Research Committee. Setting: Monocentric study performed at Dante Pazzanese Institute of Cardiology, Sao Paulo, Brazil. Patients: 40 consenting patients undergoing elective coronary artery bypass, both genders. Exclusion criteria: Chronic kidney disease; emergency procedures; reoperations; contraindication to spinal block; left ventricular ejection fraction less than 40%; body mass index above 32 kg/m(2) and use of nitroglycerin. Interventions: Patients were randomly assigned to receive intrathecal sufentanil 1 mu g/kg or not. Anesthesia induced and maintained with sevoflurane and continuous infusion of remifentanil. Main outcome measures: Hemodynamic variables, blood levels of cardiac troponin I, B-type natriuretic peptide, interteukin-6 and tumor necrosis factor alfa during and after surgery. Results: Patients in sufentanit group required less inotropic support with dopamine when compared to control group (9.5% vs 58%, p = 0.001) and less increases in remifentanil doses (62% vs 100%, p= 0.004).
