PENG (Pericapsular Nerve Group) block versus intravenous fentanyl as an analgesic technique in cardiac patients for positioning ofhip fracture: Prospective, Randomized study

Abstract

Background: The “Pericapsular Nerve Group (PENG) Block” is an alternate regional anesthetic
approach for the treatment of acute pain following hip fractures. The musculofascial plane between the
psoas muscle and the superior pubic ramus is blocked with local anesthesia using (PENG) block
technique.
Aim of work:The purpose of this study was to assess the effectiveness of (PENG) Block against
intravenous fentanyl as an analgesic method for hip fracture in cardiac patients.Patients and Methods:
After getting ethical committee approval and signed informed agreement from patients, the study
enrolled sixty cardiac patients with ASA (II-III) ranging in age from 21 to 60 years old. They were split
into two groups: group I received intravenous fentanyl (IVF) at a dose of 0.5 μg/kg body weight, while
group II received a PENG block with 20 mL bupivacaine(0.125%).
Results: VAS during positioning in PENG group was lower than intravenous fentanyl. Patient position
for spinal anesthetic was better in the PENG group than in the intravenous fentanyl group. patient
satisfaction was lowerin the IVF group than PENG group.PENG users need fewer extra analgesics than
IVF users.
Conclusion:PENG block provides greater analgesia to intravenous fentanyl during position and post
operation. PENG block gives superior analgesia, patient satisfaction, and patient position during spinal
anesthesia of hip fracture than intravenous fentanyl.
