Lead Sponsor
Ospedale Edoardo Bassini
Brief Summary

Optimal pain control with limited muscle weakness is paramount for a swift initiation of physical therapy and ambulation. Fascia iliaca compartment block (FIC) has been recommended since it offers the best pain control with low risk of motor block. Pericapsular nerve group block (PENG) with lateral femoral cutaneous block (LFCN) has been proposed as an effective alternative to FIB that offers similar pain control with a considerably lower risk of motor block. The aim of this study is to compare the afore mentioned blocks and determine which one yielded the least degree of quadriceps femoris muscle weakness and the better pain control (the lowest NRS score with least need for opioids).

Detailed Description

This single-center, double blinded RCT investigation will be conducted at ASST Nord Milano - Bassini hospital. The study was approved by the ethics committee "Comitato Etico Territoriale Lombardia 3".

Each patient undergoing elective total hip replacement surgery with anterior approach will be subjected (unless contraindicated) to subarachnoid neuraxial anesthesia and immediately afterwards to a peripheral analgesic block: the FIC block or the association of PENG and FCLN block. The choice of block type will be randomized.

At the end of the procedure, a clinician unaware of the anesthetic technique used will assess the degree of residual motor block. Simultaneously, he will assess pain control in terms of NRS (Numerical Rating Scale) and the need for opioid use.

Primary Outcome Measures
NameTimeMethod
MRC at 6hsix hours after performing the regional anesthesia technique

evaluation of the degree of weakness or residual paresis of the quadriceps femoris muscle on the operative side using 'the Oxford Scale' (aka Medical Research Council Manual Muscle Testing scale or MRC scale) The MRC scale is a 0-5 scale, with zero meaning "no contraction " and five meaning "Full range of motion against gravity with full resistance".

MRC at 48h48 hours after performing the regional anesthesia technique

evaluation of the degree of weakness or residual paresis of the quadriceps femoris muscle on the operative side using 'the Oxford Scale' (aka Medical Research Council Manual Muscle Testing scale or MRC scale) The MRC scale is a 0-5 scale, with zero meaning "no contraction " and five meaning "Full range of motion against gravity with full resistance".

MRC at 24h24 hours after performing the regional anesthesia technique

evaluation of the degree of weakness or residual paresis of the quadriceps femoris muscle on the operative side using 'the Oxford Scale' (aka Medical Research Council Manual Muscle Testing scale or MRC scale) The MRC scale is a 0-5 scale, with zero meaning "no contraction " and five meaning "Full range of motion against gravity with full resistance".
