简要总结
This prospective, randomized, double-blind controlled trial aims to compare the effects of intrathecal clonidine and nalbuphine as adjuvants to 0.75% hyperbaric ropivacaine in patients undergoing infraumbilical surgeries under spinal anaesthesia.
A total of 75 adult patients (ASA I–II) aged 18–60 years will be randomly assigned into three groups:
Group RC: Ropivacaine + Clonidine (30 mcg)
Group RN: Ropivacaine + Nalbuphine (2 mg)
Group RS: Ropivacaine + Normal Saline (control)
Primary outcome includes onset time of sensory and motor blockade. Secondary outcomes include duration of block, hemodynamic parameters, time to first rescue analgesic, and incidence of adverse effects. Patients will be monitored intraoperatively and for 24 hours postoperatively. The study will be conducted at Sharda Hospital, Greater Noida over 18 months.
