ContextProfound side-effects following intrathecal use of local anesthetics as the sole drugs of choice make spinal anesthesia for open appendicectomy uncommon.AimThe aim of this study was to evaluate the effectiveness of intra-operative analgesia produced by intrathecal tramadol and fentanyl during bupivacaine spinal anesthesia for open appendicectomy.Settings And DesignA prospective randomized study was performed.Materials And MethodsA total of 186 American Society of Anesthesiologists 1 or 11 patients scheduled for emergency open appendicectomy were analyzed. Group FB ( n = 62) received intrathecal fentanyl 25 μg plus 3 ml of 0.5% hyperbaric bupivacaine, Group SB ( n = 62) received 0.5 ml normal saline plus 3 ml of 0.5% hyperbaric bupivacaine and Group TB ( n = 62) received intrathecal tramadol 25 mg plus 3 ml of 0.5% hyperbaric bupivacaine. Visual analog scale scores and frequency of subjective symptoms among patients in the three groups formed the primary outcome measure of this study.ResultsEffective intraoperative sensory block was achieved in 100% of patients in group FB and TB while 29 (46.8%) patients in group SB had ineffective sensory block ( P = 0.0001). The pain free period was significantly longer in patients in Group FB than Group SB and TB. Mean time for Group FB with regard to first analgesic request was 304.73 ± 67.91 min, Group SB was 146.59 ± 36.62 and Group TB was 238.39 ± 61.28 min. Incidence of complications were comparable among the three groups.ConclusionThis study showed that intrathecal tramadol (25 mg) can safely replace intrathecal fentanyl (25 μg) in the management of visceral pain and discomfort during subarachnoid block for appendicectomy.
