Fascia Iliaca Compartment Block (FICB)
All patients recruited into the study are admitted to hospital with a fractured neck of femur and will receive an analgesic nerve block, called a fascia iliaca compartment block (FICB) prior to surgery. The intervention in the study is to place an intravenous catheter for sampling blood following injection of local anaesthetic during the nerve block. Blood sampling involves removal of less than 5ml of blood on each occasion and occurs at the following time intervals following FICB: 10, 20, 30, 45, 60, 75, 90, 105, 120, 240 minutes. Pain scores at rest and on 15 degree passive straight leg raise will be recorded using the Numerical Rating Scale (NRS-11) system.

Blood samples will be tested using a validated GC-MS and ELISA assays to produce data on plasma levobupivacaine and alpha-1 glycoprotein concentration.

Investigators will review patient records to obtain relevant data on patient age, weight, height, gender, renal function, albumin and concurrent medication, intravenous fluid administration and supplemental analgesia provided.
Primary Outcome(s)
Pharmacokinetic profile of levobupivacaine is measured through blood testing on samples taken at baseline and 10, 20, 30, 45, 60, 75, 90, 105, 120, 240 minutes after the FICB.
Secondary Outcome(s)
1. Relationship between time and pain after fascia iliaca compartment block is measured through blood testing and visual analogue scale (VAS) on samples taken at baseline and 10, 20, 30, 45, 60, 75, 90, 105, 120, 240 minutes after the FICB
2. Range of alpha-1 glycoprotein plasma concentration in elderly patients with hip fracture is measured through blood testing on samples taken at baseline and 10, 20, 30, 45, 60, 75, 90, 105, 120, 240 minutes after the FICB
3. Patient demographics, renal function, intravenous fluid administration, supplemental analgesia requirements are measured using medical record review at baseline
