The Efficacy of Intrathecal Bupivacaine in Combination with Gen-eral Anesthesia Versus General Anesthesia Alone on Time to Extuba-tion in Patients With Coronary Artery Bypass Graft (CABG) Sur-gery

Objective: we compared the use of intrathecal bupivacaine in combination with gen-eral anesthesia to general anesthesia alone in patients undergoing coronary artery by-pass grafting (cabg) surgery for its impact on time to extubation.methodology: in this case control double blind study we compared 34 patients in imam khomeini hospital, ahwaz, iran, from may 2011 to september 2011.the pa-tients were randomly assigned to receive general anesthesia with prior administration of intrathecal bupivacaine 0.5% at a dosage of 20 mg (bupivacaine or case group n = 17) or general anesthesia alone (control group n = 17) according to a simple comput-er-generated list.results: mean extubation time in bupivacaine group was213.00 ± 3.06 (3h and 33m) and in control group was 257.12 ± 4.49 minutes (4h and 17m).the difference between two groups was significant(p < 0.05).conclusion: intrathecal bupivacaine offers promise as a useful adjunct in reducing postoperative time to extubation in coronary artery bypass grafting (cabg) surgery.
