Abstract

Spinal anesthesia is the easiest and most affordable anesthesia available for infra-umbilical surgeries. However, due to the lower dose of anesthetic agent required to induce, it doesn't provide adequate analgesia during the postoperative period. Various adjuvants have been tried to avoid intraoperative visceral and somatic pain. Fentanyl is an opioid that has been used previously as a neuralgic adjuvant. Dexmedetomidine is a new, highly selective alpha 2 agonist drug that has a lesser side effect profile than opioids and gives better analgesia. Methods: A comparative controlled trial was done in Government General Hospital, Guntur on 70 patients. They were divided into two groups. One group received 15 mg of 0.5% Levobupivacaine (Isobaric) +25 μg Fentanyl 0.5ml. while the other group received 15 mg of 0.5% Levobupivacaine (Isobaric) +5 μg Dexmedetomidine (made into 0.5ml with normal saline). Various parameters were compared like demographic details and the duration for sensory block and motor block. Time to achieve maximum sensory block and motor block. Time required for rescue analgesia and side effects profile. Results: Patients in Dexmedetomidine + Levobupivacaine group (BD) hada rapid onset of sensory block and motor block, shorter Time for Maximum sensory block and motor block, longer Time at which rescue analgesia was required, and a less painful experience. Conclusion: Intrathecal dexmedetomidine administration has a longer motor and sensory block, and reduced demand of analgesics when compared to Fentanyl
