Effects of Pericapsular Nerve Group Block Applied in Patients Undergoing Hip Fracture Surgery.

This prospective randomised controlled study included a total of 70 patients aged 30-85 years who underwent hip fracture surgery under spinal anaesthesia. Patients were randomly divided into two groups using the sealed envelope method, Group I: those who received PENG block (n:35) and Group II:Those who did not receive PENG block (control group) (n: 35).

All patients will undergo hip fracture surgery by the same surgical team. Each patient will be informed about the procedure to be performed during anesthesia and surgery, and signed informed consent will be obtained before the procedure.Patients in Group I who will undergo the PENG block method; Before surgery, after spinal anesthesia, PENG block is performed under sterile conditions under ultrasonography guidance. With the patient supine, a 2-5 MHz, low-frequency, curvilinear probe is placed in the transverse plane medial to the anterior inferior iliac spine (AIIS), with the medial end of the probe rotated approximately 45° counterclockwise to align with the superior pubic ramus.

With the PENG block, an 80 mm block needle is placed in the fascial plane between the psoas tendon and the pubic ramus and 20 ml of 0.5% bupivacaine is administered.

As for the patients in Group II (control group); It is a routine practice at the end of surgery; 10 ml 0.5% bupivacaine + 10 ml 2% lidocaine is infiltrated into the surgical area by the surgical team.

For routine postoperative multimodal analgesia, intravenous PCA (patient controlled analgesia) was administered to patients in both groups with tramadol 50 mg at a basal rate of 10 mg / hour after loading (20 mg bolus dose + 30 minutes lock time) and paracetamol 10 mg / kg iv. (Given every 8 hours)

• PENG block adverse events [Срок оценки: between the time surgery starts and the 48th hour]
• length of hospital stay [Срок оценки: between the time of hospitalization for the operation and discharge (day)]
