Clinical Trial Summary

Hip fracture is a common cause of surgery, especially in elderly patients. Unilateral spinal anesthesia in hip fracture surgery can prevent the undesirable effects of spinal anesthesia due to sympathetic blockade. However, severe pain in hip fracture patients limits the positioning required for unilateral spinal anesthesia. The sedation and analgesia required to position patients with fractured hip remains inferior may cause respiratory depression, hemodynamic instability or postoperative cognitive impairment, especially in elderly patients. Lower extremity peripheral blocks can be used preoperatively to minimize the use of sedatives that may be required during positioning and to provide effective and safe analgesia.

Clinical Trial Description

In the study, one anesthesiologist (Anesthesiologist A) will perform the relevant peripheral blocks according to the groups to which the patients are randomized; the other anesthesiologist (Anesthesiologist B) will perform unilateral spinal anesthesia in all patients blinded to the peripheral blocks. On the day of surgery, the patients will first be taken to the block application room and standard monitoring (ECG, pulse oximetry, noninvasive blood pressure) will be applied in the supine position. In the pre-block period, individual pain assessment will be performed with the Visual Analog Scale (VAS - 0 cm = no pain / 10 cm = unbearable pain) and recorded on the case report form. After the pain assessment, disinfection of the block area will be performed with 10% povidone iodine (Batidex) in accordance with surgical sterilization rules. After sterilization, the relevant peripheral block will be performed by Anesthesiologist A under USG guidance. Intermittent negative aspiration will be performed during all interventions to detect possible vascular puncture. All groups will receive 30 ml of local anesthetic solution containing 5 mcg/ml adrenaline and bupivacaine at 0.25% concentration. Group 1 (PENG Block): Convex USG Probe (1-5 mHz) is placed transversely on SIAS (Spina Iliaca Anterior Superior). The probe is then rotated 45 degrees and aligned with the pubic ramus. In this position, the iliopubic eminence, ilipsoas muscle-tendon, femoral artery and pectineus muscle are observed. A 100 mm 21G block needle (Stimuplex A®:B. Braun Melsungen AG, Japan) is inserted in-plane from lateral to medial to the musculofascial plane with the psoas tendon in front and the pubic ramus behind and the injection is performed. Group 2 (Suprainguinal Fascia Iliaca Compartment Block) : Linear USG Probe (7-13 mHz) is placed parasagittal to obtain an image of the SIAS. The probe is then shifted medially to identify the fascia iliaca, iliac muscle, internal oblique muscle and deep circumflex iliac artery. A 50 mm 21G block needle (Stimuplex A®:B. Braun Melsungen AG, Japan) is advanced in-plane from caudal to cephalic and injected between the fascia iliaca and iliac muscle. Group 3 (3-1 Block) Linear USG Probe (7-13 mHz) is placed at the femoral fold and femoral vein-arterial-nerve is visualized. The femoral nerve is located below the fascia iliaca. At this point, a 50 mm 21G block needle (Stimuplex A®:B. Braun Melsungen AG, Japan) is inserted in-plane from lateral to medial and injected lateral to the femoral nerve. After injection, pressure is applied distal to the needle entry site to spread the local anesthetic proximally in the nerve sheath. The VAS score of the patients will be reevaluated and recorded during positioning for unilateral spinal anesthesia 30 minutes after the block is performed. Patients with VAS > 3 will be administered sedoanalgesia with propofol - ketamine combination as rescue analgesia before spinal anesthesia and recorded in the case report form. (1 = need sedoanalgesia / 2 = no need sedoanalgesia) Unilateral spinal anesthesia will be administered by Anesthesiologist B after the patient is positioned so that the fractured hip remains at the bottom. The quality of the patient's position will be evaluated by Anesthesiologist B administering spinal anesthesia and recorded on the case report form (0 = inadequate, 1 = adequate, 2 = good, 3 = optimal) All patients will be routinely administered 1000 mg acetominophen 3x1 in the postoperative period. All patients will be followed up in terms of VAS score and possible opioid requirement in the postoperative 24 hours and evaluated in terms of satisfaction with the procedure. Patients will be monitored for 24 hours in terms of undesirable side effects and if signs of vascular puncture, hematoma, LA toxicity are observed, these events will be recorded in the case report form and serious adverse reactions will be reported. ;
