Hip FracturesNCT04677348
Comparison of PENG Block and FICB in Hip Fracture Patients
A study testing Pericapsular nerve group (PENG) block and Fascia iliaca compartment block (FICB) in people with Hip Fractures and Regional Anesthesia, run by Asan Medical Center at 1 site in South Korea.
Trial summary
Fascia iliaca compartment block (FICB) has been considered the block of choice for patients with hip fracture. However, pericapsular nerve group (PENG) block, one of the relatively newly-developed blocks, could be also used for analgesia in patients with hip fracture. Read more about this study

About this study
Official title: Comparison of Analgesic Effect of Pericapsular Nerve Group Block and Suprainguinal Fascia Iliaca Compartment Block on Dynamic Pain in Patients Undergoing Hip Fracture Surgery: a Randomized Controlled Trial
Fascia iliaca compartment block (FICB) has been considered the block of choice for patients with hip fracture. However, pericapsular nerve group (PENG) block, one of the relatively newly-developed blocks, could be also used for analgesia in patients with hip fracture. Since PENG block could block the accessory obturator nerve, PENG block might have greater analgesic effects compared to FICB theoretically. However, the comparison of these two blocks in patients with hip fracture has not performed in clinical setting. Thus, we aimed to compare the analgesic effect of PENG block and FICB.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Pericapsular nerve group (PENG) blockProcedure or surgery
ultrasound-guided PENG block with 0.3% ropivacaine 20cc
Fascia iliaca compartment block (FICB)Procedure or surgery
ultrasound-guided suprainguinal FICB with 0.3% ropivacaine 30cc
| Study group | Role | What they receive |
|---|---|---|
| PENG group | Experimental | pericapsular nerve group (PENG) block before surgery Receives: Procedure: Pericapsular nerve group (PENG) block |
| FICB group | Active comparator | suprainguinal fascia iliaca compartment block (FICB) before surgery Receives: Procedure: Fascia iliaca compartment block (FICB) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Efficacy of each block (Pain score)
We will assess the dynamic pain (pain during a movement) using NRS before and 20-30min after applying the assigned block. Then, we will calculate the change of NRS at the two time-points.
NRS: Numerical rating scale (0, no pain; 10, the worst pain imaginable)
Measured: before surgery
Secondary outcomes (5)
change of blood pressure (systolic, diastolic, mean blood pressure)
We will evaluate the blood pressure before and 20-30min after applying the assigned block. Then, we will calculate the change of blood pressure at the two time-points.
Measured: before surgery
postoperative pain score
resting and dynamic pain using NRS at postoperative 6, 24, 48hours
NRS: Numerical rating scale (0, no pain; 10, the worst pain imaginable)
Measured: postoperative 6, 24, 48hours
postoperative opioid consumption
morphine-equivalent dose
Measured: postoperative 24, 48hours
postoperative motor function
motor function of quadriceps femoris
grade5: normal power grade4: movement possible against some resistance grade3: movement against gravity but not resistance grade2: movement possible if gravity eliminated grade1: flicker of contraction possible grade0: complete paralysis
Measured: postoperative 6, 24, 48hours
change of heart rate
We will evaluate the heart rate before and 20-30 min after applying the assigned block. Then, we will calculate the change of heart rate at the two time-points.
Measured: before surgery

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Fascia iliaca compartment block (FICB) has been considered the block of choice for patients with hip fracture. However, pericapsular nerve group (PENG) block, one of the relatively newly-developed blocks, could be also used for analgesia in patients with hip fracture. Since PENG block could block the accessory obturator nerve, PENG block might have greater analgesic effects compared to FICB theoretically. However, the comparison of these two blocks in patients with hip fracture has not performed in clinical setting. Thus, we aimed to compare the analgesic effect of PENG block and FICB.

What does the primary outcome measure?
Efficacy of each block (Pain score) (time frame: before surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04677348, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Mar 2022; AzTrials last refreshed its copy on 8 Nov 2026.
