About this trial

Hip fracture (HF) is one of the major worldwide problems that constitute a significant mortality rate, ranging from 14- 36% in the first year after injury, and is associated with profound temporary and sometimes permanent impairment of independence and quality of life in the geriatric population. Surgical treatment is considered the best option for patients with hip fractures,s especially in the elderly, however, it is associated with moderate to severe postoperative pain.

Pain is one of the main factors limiting ambulation, increasing the risk of thromboembolism by immobility and causing metabolic changes that affect other systems. Therefore, individualized pain management with the use of appropriate analgesic techniques is of paramount importance. Moreover, early intervention of rehabilitation aiming at a better postoperative recovery may reduce the length of hospital stay and return to daily. Effective pain management is one of the crucial components in enhanced recovery after surgery (ERAS).

• Numerous regional anesthetic techniques have been used to provide analgesia following hip fracture surgery, including intrathecal morphine, epidural analgesia, fascia iliaca block, lumber plexus block, and sacral plexus block, however, each of these techniques has specific limitations that prevent them from being the analgesic technique of choice for hip fracture surgery.

To our knowledge, there is no study done to compare circum-psoas block versus the combined lumbar and sacral plexus blocks as pre-emptive analgesia in patients undergoing hip fracture surgery under general anesthesia.

Trial outcomes

Primary outcomes

1

Assess change of Visual analogue scale (VAS)

On a scale of 0-10, the patient will learn to quantify postoperative pain where 0= No pain and 10= Maximum worst pain

Time frame
at 30 minutes, 2 hours, 4, 6,12, 24 hours postoperatively

Secondary outcomes

1

Assess sensory block levels

by using alteration of pinprick sensation compared to the contralateral side on the dermatomes supplied by blocked nerves

Time frame
at 2 hours postoperatively
2

Total dose of rescue analgesia

once the VAS score will be ≥ 3, rescue analgesia in the form of 1 μg/kg fentanyl will be given and the total dose consumed will be recorded

Time frame
in the first 24 hour postoperatively
