Volume Dependent Effect of Pericapsular Nerve Block

Post Operative Pain Clinical Trial

Official title: Comparison of the Volume Dependent Effect of Pericapsular Nerve Block in Patients Operated for Femur Fracture: A Randomized Prospective Study

Status Completed

Clinical Trial Summary

In PENG block technique, the local anesthetic agent is injected between the psoas tendon and the pubic ramus to block the sensory branches of the nerves which innervates the hip capsule for providing analgesia without causing muscle weakness. Since the PENG block is a facial plane block, it causes a volume dependent distribution. There are a few case reposts and cadaveric studies on volume dependent effect of analgesia and motor weakness of PENG block. In our study, we aimed to evaluate the clinical effects of the volume-dependent efficacy of PENG block.

Clinical Trial Description

Femur fracture is the one of the most common case groups and it is seen mostly in the elderly patient population with comorbidities. For these patients, perioperative, postoperative analgesia and early mobilization are important to reduce cardiopulmonary complications and morbidity. Femoral fracture operations are mostly performed under spinal anesthesia especially under unilateral spinal anesthesia to sustain more stable hemodynamics. The lateral decubitus position, which is used for unilateral spinal anesthesia, is a painful position for these patients. Intravenous opioids are used for this procedure, however they have possible side-effects, such as sedation, inhibition of respiratory, lower blood pressure. Because of these reasons, pericapsular nerve block (PENG) has been applied recently to avoid complications. By using PENG block , positioning for spinal anesthesia is easier for patients and anesthesiologists, and postoperative analgesia can be provided. By PENG block, the local anesthetic agent is injected between the psoas tendon and the pubic ramus to block the sensory branches of the nerves innervating the hip capsule, thus providing analgesia in patients, but muscle weakness is not expected. Becacuse PENG block is a facial plane block, it shows a volume dependent distribution. There are a few case reposts and cadaveric studies, which are showing volume depend effect of analgesia and motor weakness of PENG block. In our study, we aimed to evaluate the clinical effects of the volume-dependent efficacy of PENG block. ;
