The Anterior Approach of the Combined Lumbar and Sacral Plexuses Block for Analgesia of Lower Limb Surgeries

Not Applicable
Recruiting
Conditions
Lower Limb Fracture
Interventions
Procedure: one point combined Lumbar and sacral plexus block
Registration Number
NCT06019754
Lead Sponsor
Zagazig University
Brief Summary

lumbosacral plexus block (LSPB) has been widely applied in orthopedics departments due to its advantages, including reduction in the application of opiates, decreasing the occurrence of acute pain, promoting early activation, and shortening the time of hospital stay. LSPB is a peripheral regional technique of anesthesia and analgesia, that provides a block of the main components of the lumbosacral plexus.

Detailed Description

Traditional ultrasound-guided lumbar plexus block combined with sacral plexus block requires separate blocks at different sites, requiring the lateral decubitus or prone position, which may be suboptimal in patients with severe pain. we present an anterior approach for combined lumbar and sacral plexus blocks with a one-point puncture.

Primary Outcome Measures
NameTimeMethod
Total intraoperative and postoperative opioid consumptionTotal fentanyl used intraoperative and total morphine consumed up to 24 hours postoperative

The total fentanyl doses consumed in the entire operative procedure and morphine consumed for 24 hours postoperative will be calculated.

Secondary Outcome Measures
NameTimeMethod
(NRS) score assessment pre-block, 30 min post-block , and postoperatively in the recovery room, and then it will be repeated 3 h, 6h, 12h, and 24, hourspreoperative and postoperatively pain (NRS) score assessment for 24 hours

Numerical Pain Score (NRS) ranges from 0 to 10, where 0 is no pain, and 10 is the worst pain imaginable. Adequate pain control will be considered at Numerical Pain Score (NRS) \< 4.

Pain will be assessed using (the NRS) score preoperatively before the block and 30 min post-block, then postoperatively in the recovery room, 3 h, 6h, 12h, and 24 hours.

Block success assessment using perfusion index (PI) before and after performing the blockRecording Perfusion index readings at baseline and 10, 20, 30 min. post block

Perfusion index (PI) values rise with successful peripheral nerve blocks. If PI is not changed, this means block failure
