Aim: The aim of the present study is to determine the effect of adding dexmedetomidine and fentanyl to levobupivacaine in subarachnoid block for LSCS on the outcome of the patient. Methods: This is a comparative study which is carried out in the Department of Anesthesiology for duration of six months, which included 150 patients as study participants. Patients were divided into three equal groups. Group I, Group II and Group III. Patients’ detailed demographics were recorded after taking verbal and written consent. Results: The mean age of the patients in group I was 28.42 ± 6.54 years with BMI 23.17±8.32, mean age in group II was 27.33 ±7.53 years with BMI 24.46 ± 6.14 and in group III mean age was 26.94 ±9.51 years with BMI 24.76 ±4.36. Patents arterial pressure and heart beat per minute recorded. In Group III and II (5.15±2.38 min, 6.04±5.16 min), the maximum in Group I (8.02± 2.18 min) time needed for the highest level of sensory block was the shortest gap between three categories (p < 0.001). Bromage Scale 3 was averaged in a similar way, less in Group III (2.88 ±1.52) and statistically significant across the three groups (p < 0.001). The time needed for sensory regression to level S1 (sensory block duration) in Group II was maximum (501.05 ± 14.38 min) and high between groups of three (p< 003). The time gap needed in Group II (403.37 ±10.05 min) and Group I (300.06±4.46 min) for the first analgesic requirement was highly important (p < 0.001) and the most significant. Frequency of side effects (Hypotension, Nausea/Vomiting, Respiratory depression) Shivering were also observed between the patients of these three groups. Conclusion: We observed and concluded that for an adjuvant of 0.5percent isobaric levobupivacaine, Intrathecal dexmedetomidine induces both prolonged motor blockage and post operative analgesia than fentanyl.
