With the goals of attenuating the surgical stress response, reducing morbidity, and improving patient outcomes, one cardiac anesthesiologist at a Canadian tertiary care centre initiated the use of a novel anesthetic approach that combines total spinal anesthesia (TSA) with intrathecal (IT) morphine and general anesthesia (GA), hereafter referred to as TSA.
Based on the evidence from Lee and associates' (2003) research and a subsequent ITB study (Jacobsohn, Lee, Amadeo, Syslak, Debrouwere, & Bell, 2005), the ITB-GA technique has been modified as described in Lee and Jacobsohn (2008) to combine total spinal anesthesia with IT morphine and GA for cardiac surgery patients.
