About this study
Official title: Postoperative Analgesia After Total Hip Arthroplasty: Comparative Evaluation of Pericapsular Nerve Group Versus Fascia Iliaca Compartment Block in a Randomized Controlled Trial
The aim of this study is to compare the effectiveness of pericapsular nerve group (PENG) block versus fascia iliaca compartment block (FICB) for postoperative pain relief following total hip arthroplasty (THA).
Read the detailed description
Total hip arthroplasty is a widely used surgical treatment intervention for treating hip conditions such as femur neck fractures and advanced hip osteoarthritis.
Hip fractures are quite common, regardless of the age of the population (young or old), and they are extremely painful. A hip fracture is a serious injury with potentially life-threatening complications, and it is a common orthopedic emergency in elderly individuals. Early surgery within 48 hours of a fracture has been found to lower mortality and complication rates.
The pericapsular nerve group block is a novel regional analgesia technique to decrease pain after total hip arthroplasty (THA) while preserving the motor function. The local anaesthetic is deposited using this method in the fascial plane between the psoas muscle and the superior pubic ramus, which aims sensory branches of the obturator, accessory obturator, and femoral nerves in the anterior capsule of the hip.
Fascia iliaca compartment block, for procedures on the femur and hip joint, is still a well-liked regional anaesthetic technique. Studies have found that FICB prevents complications by anaesthetizing the femoral nerve far from critical neurovascular structures while still giving enough analgesia.
Both blocks could be used to effectively reduce pain intensity up to 24 hours, total opioid consumption, and length of hospital stay in THA patients.

Patients received an ultrasound-guided pericapsular nerve group (PENG) block.
| Study group | Role | What they receive |
|---|---|---|
| Group A | Experimental | Patients received an ultrasound-guided supra-inguinal fascia iliaca compartment block. Receives: Other: Fascia iliaca compartment block |
| Group B | Active comparator | Patients received an ultrasound-guided pericapsular nerve group (PENG) block. Receives: Other: Pericapsular nerve group block |
What is being measured
The primary outcome is the main question the study is designed to answer.
Degree of pain
Degree of pain was assessed using the Visual Analogue Scale (VAS). VAS is ranging from 0 to 10, where 0 is no pain and 10 is maximum pain. VAS was recorded at 0, 2, 4, 6, 12, 18, and 24 hours postoperatively.
Measured: 24 hours postoperatively
Total amount of nalbuphine consumption
If the postoperative Visual Analogue Scale (VAS) was greater than 3, an intravenous dose of 5 mg Nalbuphine diluted in 5 mL of saline was administered as needed.
Measured: 24 hours postoperatively
Number of cases needing rescue doses
The number of cases needing rescue doses was recorded.
Measured: 24 hours postoperatively
Secondary outcomes (1)
Postoperative ambulation
Time from completion of surgery to first assisted standing and walking ≥2 meters was recorded as the ambulation time.
Measured: 24 hours postoperatively
