To compare the analgesic efficacy and motor function of FNB and PENG block in hip fracture surgery.
Femoral Nerve Block (FNB) and
pericapsular nerve group (PENG) block are renowned regional analgesic
procedures, due to their opioid-sparing effects. This study favored the
efficacy of PENG block in terms of pain relief.
To compare the analgesic efficacy
and motor function of FNB and PENG block in hip fracture surgery.
Sixty patients were randomly given
either FNB or PENG block in this single-center double-blinded randomized
comparative study. Pain scores (via Numeric Rating Scale (NRS) on a scale of 0
to 10) were regarded as the primary outcome. Quadriceps strength, opioid usage,
complications, duration of hospital stay, and patient-reported outcomes after
the surgery was regarded as the secondary outcomes.
As per the NRS scale, the patients in the PENG group had better pain relief compared to the patients with the FNB group at day 0 of the surgery, as shown in the below table:
PENG group had better preserved
Quadriceps strength in the recovery unit (examined via Oxford muscle strength
grading, 60% intact in PENG group as compared to none in the FNB group) and on
day 1 (90% intact as compared to 50%).
The PENG block patients had reduced
postoperative pain in the recovery room with no dissimilarity discovered by day
1 of the surgery. No differences perceived in recovery quality inspite of the
brief analgesic advantage and better quadriceps strength.
