The Effect of Intrathecal Bupivacaine Plus Sufentanil on Intraoperative Hemodynamics During Elective Coronary Artery Bypass Surgery

Ali Dabbagh, Samira Rajaei and Hasan Taghizade

Introduction: Intrathecal opioids have been used for many patients undergoing surgical operations to improve clinical outcomes. Cardiopulmonary bypass in patients undergoing coronary artery bypass graft surgery carries a number of drawbacks, namely hemodynamic derangements. Several methods have been used to suppress this state; among them is sympathetic blockade by neuraxial anesthesia. This study assesses the effect of intrathecal adjuvant bupivacaine plus sufentanil on intraoperative hemodynamic changes in elective coronary artery bypass surgery.

Methods: In a double-blind, randomized, placebo-controlled clinical trials, 80 patients scheduled for elective CABG were randomly assigned into 2 groups. One group received intrathecal sufentanil (S) and the other group received the same dose of sufentanil plus supplemental bupivacaine (SB). All the patients were similar regarding other items. Hemodynamic and clinical outcomes including blood pressure values were measured during and after the operation.

Results: There were more stable hemodynamic parameters in the SB group. Also, the SB group patients were extubated sooner than the other patient group.

Discussion: The administration of intrathecal sufentanil plus bupivacaine seems to keep the hemodynamic status of the patients more stable than intrathecal sufentanil alone.
