PENG Block Plus Local Infiltration Compared to PENG Block Alone in Hip Surgery

Pain Clinical Trial

Official title: Evaluation of Analgesic Effect of Added Local Infiltration to Pericapsular Nerve Group Block in Traumatic Hip Surgery

Status Recruiting

Clinical Trial Summary

Summary:

Pain control after hip surgery is quite important for patients' recovery. Many regional techniques are available with the focus on motor sparing block to speed patient recovery.

The investigators will compare pericapsular nerve group (PENG) block in addition to local skin infiltration to PENG block alone. The study population will be included for patient traumatic hip surgery. The study population will be divided into group. First group will receive PENG block and local anaesthetics infiltration and second group will receive PENG block.

Our primary outcome is to compare numeric rating scale (NRS) between studied groups, and morphine requirements in the first 24 hours as a secondary outcome.

Clinical Trial Description

Aim of the study:

The aim of the study is to improve quality of patient's post-operative recovery after hip surgery.

Study objectives:

To compare Patient numeric rating scale (NRS) scores after hip surgery for patients receiving PENG block and local skin infiltration

Study question:

Will PENG block and local infiltration provide significant analgesia for hip surgery than PENG block alone?

Null Hypothesis:

Local infiltration addition to PENG block will not provide significant analgesia to PENG block alone.

Alternative hypothesis:

Local infiltration addition to PENG block will provide significant superior analgesia to PENG alone.

Study Design:

Single blinded randomized clinical trial. Ethical approval will be obtained from Suez Canal University. Patients' enrolment will be obtained preoperatively. Patients' demographic data will be recorded (age, weight, BMI, and gender).

An informed consent will be obtained during enrolment explaining the aim of the study and complication of the techniques. Patient will have the right to withdraw from the study at any time.

Patients will be randomly allocated to either of the studied group through the following method:

Randomization of the patients meeting the inclusion criteria will be achieved by a computer-generated random sequence, and this sequence will be concealed in sealed numbered envelopes, labelled Group A (study group) carry the label Group B (control group).

Methods:

Group A (study group) will receive both PENG block and local infiltration at the end of the surgery. Group B (control group) will receive PENG block without local infiltration.

Spinal anaesthesia will be administered to the patient using 10-12.5 mg heavy 0.5% bupivacaine at L3-L5 lumbar spine using 25 G spinal needle.

If spinal anaesthesia is contraindicated or failed, patients will have general anaesthetics.

General anaesthesia will be induced with 1-2 mcg/kg fentanyl, propofol 1-2 mg/kg, and appropriate muscle relaxant.

Block will be administered for trauma patients PENG block will be administered as following:

A curvilinear US sound probe will be placed in a transverse plane over anterior superior iliac spine and rotated 45 degrees anticlockwise till identifying femoral vessels, iliopubic eminence, iliopsoas muscle tendon in the view. A 100 mm echogenic needles (SonoPlex STIM, Germany) will be advanced from lateral to medial and injecting 20 ml of 0.25% bupivacaine below the psoas tendon.

A 20 ml of 0.25% bupivacaine will be infiltrated by the surgeons to the tissues at the end of the surgery.

Pain management:

All patients will receive 1g of paracetamol, 30 mg Ketorolac, and 8 mg Dexamethasone after spinal anaesthesia.

Postoperatively 1g of paracetamol four times a day, ketorolac 30 mg twice a day for 48 hours. Intravenous morphine 2 mg every 10 minutes will be given to the patient if NRS score ≥ 4 till pain is controlled as rescue analgesics.

Morphine requirement will be assessed in recovery and then every 6 hours, in the first 24 hours after surgery. If the pain score > 4, patient will get 2 mg IV morphine. Pain will be reassessed after 10 minutes for further analgesia requirement. ;
