PENG block with antithrombotic

Details and patient eligibility

About

PENG block will be done on patients with hip fracture either receiving antithrombotic therapy or not under ultrasound guidance

Full description

Patients will be randomized into two groups:

Group A (Antithrombotic Therapy Group): 50 Patients on continuous antithrombotic therapy will receive BENG block.

Group C (Control Group): 50 Patients without antithrombotic therapy will receive BENG block.

Intervention:

PENG Block: Standardized administration of the PENG block will be performed by experienced anesthesiologists for both groups using ultrasound device.

The patients will be subjected to standard monitoring and received nasal cannula oxygen (2 L/min). Midazolam (1-2 mg) will be administered intravenously for light sedation.

Under sterile conditions, a low-frequency curvilinear probe of ultrasound (SonoSite S-Nerve Machine, Fujifilm) is initially placed in a transverse plane over the anterior inferior iliac spine, and is then rotated parallel to the pubic ramus to obtain a short-axis view of the iliopsoas muscle and tendon lying on the ramus pubic adjacent to the iliopubic eminence. After skin infiltration with 1-3 mL 1% lidocaine, a 23 G, 70 mm insulated block needle is inserted in-plane in a lateral-to- medial direction to place the tip in the musculofascial plane between the psoas tendon and the pubic ramus. A total of 20 mL 0.5% bupivacaine (AstraZeneca, EGYPT) is injected slowly in 5 mL increments with intermittent aspiration and under constant ultrasound surveillance for adequate fluid spread. Thirty minutes after the block completion, standardized endotracheal general anesthesia is induced with propofol (2-2.5 mg/kg), fentanyl (0.5-1,5 μg/kg), and atracurium (0.5 mg/kg).maintenance of anesthesia is done with sevoflurane (2-2.5%) with o2and air 60:40% Antithrombotic Management: Clear protocols for managing antithrombotic therapy in Group A will be implemented, considering perioperative bleeding risk
