Geriatric patients suffer from hip fractures very often. Delirium is a perioperative neuropsychiatric complication that is characterized by sudden change of mental status, inattention, disorientation and memory impairment with fluctuations of symptoms during the day. Delirium causes increased morbidity and mortality, decreased postoperative functional activity and may predispose to dementia.

Perioperative pain may be an important predisposing factor to delirium. Intravenous opioids have been widely used to relieve patients with hip fracture from pain, but they have a lot of complications and have been correlated with delirium as well. Fascia Iliaca compartment block is a peripheral compartment nerve block that is used in hip surgeries. Use of this compartment nerve block to protect geriatric patients from delirium has not been studied.

The objective of this trial will be to establish whether the ultrasound-guided suprainguinal fascia iliaca compartment block is capable of protecting geriatric patients with hip fracture from delirium as compared to placebo
