An Assessment of the Duration of Sensory Block in 0.5% Levo Bupivacaine Heavy Versus 0.75% Ropivacaine Heavy in Infraumbilical Surgeries Under Spinal Anaesthesia

Abstract

AIM:  To observe the effects of 0.5% levo-bupivacaine heavy and 0.75% ropivacaine heavy when administered intrathecally for infraumbilical  surgeries

OBJECTIVES : To assess the duration of sensory block in patients receiving 0.5% levo bupivacaine heavy and 0.75% ropivacaine heavy ; To assess the onset of sensory block with 0.5% levo bupivacaine heavy and 0.75% ropivacaine heavy ; To assess the peak level of sensory block achieved and time to peak sensory block with 0.5% levo bupivacaine heavy and 0.75% ropivacaine heavy ; To assess time to onset of complete motor block with 0.5% levo bupivacaine heavy and 0.75%ropivacaine heavy ;  To assess the duration of motor block that each of the drugs provide

MATERIALS AND METHODOLOGY : A prospective randomized observational study conducted at Sree Balaji Medical College and Hospital for a period of 1 year . 58 patients were selected for the study after applying the inclusion and exclusion criteria. A 22 gauge hypodermic needle was used to assess the sensory block and modified Bromage scale was used to assess the motor block in these patients. Data collection involved age , gender , ASA grading , hemodynamic parameters , duration of block sensory and motor block and time to recovery.

RESULTS :  In this study involving 58 patients , undergoing infraumbilical surgeries under spinal anaesthesia . levo bupivacaine and ropivacaine  were found to be comparable with no significant differences in sensory and motor blockade  between the two groups.

The duration of sensory block was found to be 180.5 mins in levo bupivacaine and 175.3 mins in ropivacaine with both the durgs being comparable to one another

CONCLUSION :  . The results indicate that both 0.5% levo-bupivacaine heavy and 0.75% ropivacaine heavy are similarly effective and safe for use in spinal anesthesia for infraumbilical surgeries. Given the comparable outcomes, the choice between these anesthetics can be guided by specific clinical contexts and patient preferences.
