Comparison between the effect of 0.2% and 0.3% Bupivacaine in fascia iliac block on postoperative pain in patients with femoral or hip fracture

Aims and Pain after surgery is a major problem for patients with fractures of the femur or hip. We studied the effect of Bupivacaine at a concentration of 0.2% and 0.3% in fascia iliac block on postoperative pain. The study was a Randomized double-blinded clinical trial. A total of 48 patients who had femur or hip fracture underwent fasia iliac block. Patients were randomly assigned to two groups receiving Bupivacaine at a concentration of 0.2% and 0.3%, respectively. Then the two groups were compared in terms of pain and satisfaction with pain control and intensity of motor block. Postoperative pain score in 0.3% group was significantly lower than 0.2%(p< 0.001) while the patient satisfaction of pain control and intensity of motor block were significantly higher in Group 0.2% (p=0.04). Onset of analgesia had no significant difference between the two groups. Bupivacaine with concentration of 0.3% in fascia iliac block could further decrease the pain score after hip or femoral fracture surgery; however patient satisfaction with pain control and intensity of motor block were higher with 0.2. % concentration of Bupivacaine.
