Brief summary
This randomized, double-blinded, placebo-controlled trial seeks to evaluate the efficacy of the pericapsular nerve group block on postoperative rehabilitation.
Detailed description
The pericapsular nerve group, or PENG block, has been recently described and shows promise in providing analgesia to the hip joint. However, the effect of this block on postoperative rehabilitation is uncertain. This study compares a preoperative PENG block to a placebo before total hip arthroplasty under spinal anesthesia. The primary outcome measure is verticalization, walking distance, ability to go out of bed, active lifting of the limb, range of motion in the hip joint, bending range of motion, and abduction range of motion. The secondary measure is postoperative pain assessment during rehabilitation.
Interventions

20 mL 0.5% ropivacaine will be injected for the PENG block
DRUG0,9% normal saline

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| postoperative Numeric Pain Rating Scale in motion | Day 2 | Numeric Pain Rating Scale. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. no pain) to '10' representing the other pain extreme (e.g. pain as bad as you can imagine or worst pain imaginable) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to first opioid | 96 hours postoperatively | Hours to first administration of an intravenous opioid drug |
| postoperative Numeric Pain Rating Scale et rest | Day 1 | representing one pain extreme (e.g. no pain) to '10' representing the other pain extreme (e.g. pain as bad as you can imagine or worst pain imaginable) |
| Functional assessment: getting out of bed without help | First day after surgery | Binary assessment of motor function evaluated at the first day after surgical procedure |
| total opioid consumption | 96 hours postoperatively | milligrams of intravenous morphine equivalents |
| Functional assessment: independent verticalization- by the balcony | First day after surgery | Binary assessment of motor function evaluated at the first day after surgical procedure |
| Functional assessment: walking by the balcony | First day after surgery | Binary assessment of motor function evaluated at the first day after surgical procedure |
| Functional assessment: active elevation of the operated limb | First day after surgery | Binary assessment of motor function evaluated at the first day after surgical procedure |
