PENG Block vs Sciatico Femoral Block in the Incidence of Post Amputation Syndroms

Not Applicable

Recruiting

• Conditions: Femoral Nerve Block; Amputation of Knee
• Interventions: Procedure: peri capsular nerve group block; Procedure: scaitico femoral block

• Registration Number: NCT05819879
• Lead Sponsor: National Cancer Institute, Egypt

Brief Summary

assess the effectiveness of peri-capsular nerve group block and scaitico femoral block in the incidence of post amputation syndrome in patients undergoing above knee amputation.

Detailed Description

The loss of a body part can lead to pain and other sensations that fall into three distinct descriptive categories, namely phantom sensations, phantom pain, and residual pain. Phantom sensations are defined as pain-free perceptions emanating from the lost body part after deafferentation, and phantom pain is a painful or unpleasant sensation in the distribution of the lost or deafferented body part 5. Phantom sensations can be a different expression of phantom pain and interfere with rehabilitation therapy by enhancing and interacting with phantom pain.

The current standard of care is pre-operative nerve blockade to prevent peripheral sensitization leading to future onset of phantom limb pain. Successful outcomes necessitate effective communication between the surgeon, anesthesiologist, and the various teams involved in the post-operative rehabilitation of the patient. A consultation with the Acute Pain Service or similar entity that performs peripheral nerve blockade pre-operatively and then follows the patient during their post-operative inpatient course is an important factor in the success in early prevention of acute and chronic pain for these patients.

Pericapsular nerve group block or PENG block is a novel regional nerve block to provide analgesia in fractured hip patients. It is primarily an ultrasound-guided (USG) technique where target area is the pelvic rim (superior pubic ramus) near iliopectineal eminence, deep to fascia of iliopsoas muscle. Articular branches of femoral nerve and accessory obturator nerves, which cross over the bony rim, are primary targets of the PENG block.however, by increasing volume of local anesthetic drug; other nerves (obturator, femoral, genitofemoral, and lateral femoral cutaneous nerve) can be blocked.

This block is a new regional anesthesia technique based on blocking the femoral nerve (FN) and accessory obturator nerve (ON) with a single injection.
