Retrospective Evaluation of Efficacy of Meta-PENG Block

Completed

• Conditions: Hip Fractures; Hip Injuries
• Interventions: Drug: meta-Peng block; Drug: Postoperative analgesia management

• Registration Number: NCT06721052
• Lead Sponsor: Medipol University

Brief Summary

The components of the lumbar plexus and capture the articular branches of hip capsule may be effectively blocked by administering a relatively high volume of local anesthetic deep to the iliacus muscle at the level of the anterior inferior iliac spine. We can provide both the blockade of the pericapsular nerve group supplying the hip capsule and the cutaneous blockade. Here, we aimed to present our novel technique we named 'deep iliacus plane block (DIPB)'.

Detailed Description

Many regional anesthesia techniques are used in hip surgeries for various goals, such as optimizing neuraxial positioning and relieving pain in the perioperative period, and have been the subject of clinical researches in the last few decades.

The lumbar plexus is important in administering anesthesia and analgesia during hip and knee surgeries. Comprising the femoral nerve (FN), lateral femoral cutaneous nerve (LFCN), and obturator nerve, it collaborates with the sacral plexus to ensure comprehensive innervation of the lower limb.

We hypothesized that by administering a relatively high volume of local anesthetic deep to the iliacus muscle at the level of the anterior inferior iliac spine (AIIS), we could effectively block the lumbar plexus components and capture the hip capsule's articular branches. We can ensure both the blockade of the pericapsular nerve group supplying the hip capsule and the cutaneous blockade. Here, we aimed to present our cadaveric evaluation and retrospective evaluation of patients underwent meta-PENG block, which we consider the proof-of-concept for our hypothesis of the technique we named 'deep iliacus plane block (DIPB)'.

Arm && Interventions

Group	Intervention	Description
Group meta-PENG block	meta-Peng block	We performed meta-PENG block in patients who underwent hip surgery under spinal or general anesthesia
Group meta-PENG block	Postoperative analgesia management	We performed meta-PENG block in patients who underwent hip surgery under spinal or general anesthesia

Primary Outcome Measures

Name	Time	Method
Pain scores (Numerical rating scale-NRS)	Changes from baseline pain scores at postoperative 1, 2, 4, 8, 16, and 24 hours	The primary aim is to compare NRS at the postoperative 24 h. Postoperative pain assessment will be performed using the NRS (0 = no pain, 10 = the most severe pain felt). The NRS scores will be recorded

Secondary Outcome Measures

Name	Time	Method
Need for rescue analgesia (tramadol)	Postoperative 24 hours period	The secondary aim is to compare rescue analgesia used in the postoperative 24 h.
