Study of use of intrathecal hyperbaric bupivacaine (2.5mg) with fentanyl for lower limb surgeries in high-risk geriatric patients
Background & Aims: In geriatric population spinal anesthesia is associated with a high incidence of hemodynamic fluctuations. Synergism between intrathecal opioids and low dose local anaesthetics have been used to achieve reliable spinal anesthesia with minimal hypotension. A single armed prospective study was conducted with an aim to establish a safe regime of intrathecal anaesthesia with opioid for ASA III and IV geriatric patients scheduled for lower limb surgery.
