Delayed Supine Position Post-Spinal Compared With Immediate Supine Position in Geriatric Patients

Impact of Two Minutes Delayed Supine Position Post-Spinal Compared With Immediate Supine Position in Geriatric Patients Undergoing Repair of Fracture Neck of Femur: A Randomized Controlled Trial

Background: Geriatric patients undergoing femoral neck of fracture (FNOF) repair are highly susceptible to spinal anesthesia-induced hypotension. This study examines whether a two-minute delayed supine position after spinal injection reduces this risk. Methods: Ninety patients aged ≥65 years undergoing FNOF surgery under spinal anesthesia were randomized into two groups. Group D remained seated for two minutes post-spinal injection; Group I was positioned supine immediately. Hemo-dynamic parameters, recorded as primary outcomes, other parameters like vasopressor use, maximum sensory level achieved, duration of surgery, and fluid administration as secondary outcomes.
