Overview
The hypothesis of this study is that patients who undergo PENG block in before Total Hip Artroplasthy (THA) surgery with spinal anesthesia will have reduced postoperative pain scores, less need for opioid analgesics and earlier mobilisation.
Detailed description
This prospective randomised controlled study included a total of 60 patients aged 40-85 years who underwent THA surgery under spinal anaesthesia. Patients were divided into two groups as PENG block (n:30) and non-PENG block (n:30). PENG block was placed in the fascial plane between the pseudotendon and pubic ramus with USG in-plane technique, 20 ml of 0.5% bupivacaine was administered and surgery was initiated. The primary outcome of the study was to investigate the effect of preoperative PENG block application on postoperative pain, opioid requirement, mobilisation time, hip joint patency and length of hospital stay in patients undergoing THA surgery. The secondary outcome was to investigate the effect of PENG block on perioperative haemodynamics and postoperative side effects.
For multimodal analgesia, 10 ml 0.5% bupivacaine + 10 ml 2% lidocaine is infiltrated into the surgical wound incision line by the surgical team at the end of surgery. After tramadol 50 mg loading with PCA device, a basal rate of 5-10 mg/hour (20 mg bolus dose + 30 minutes lock time) is given with paracetamol 10 mg/kg iv (8 hours interval).
Interventions
- Procedure Pericapsular Nerve Group (PENG) Block
With ultrasonography-guided PENG block, the femoral, obturator and accessory obturator nerve branches that provide sensory innervation of the anterior surface of the hip joint capsule are blocked .
Primary outcome measures
- postoperative pain score [Time frame: recovery room 30 min, 12., 24. and 48. hours in the postoperative period]
- mobilisation time [Time frame: 24 -48 hours]
- hip joint patency [Time frame: 24. hours]
- total opioid consumption [Time frame: 48 hours]
Secondary outcome measures (3)
- PENG block side effects [Time frame: The first 48 hours after performing the PENG block]
- Perioperative haemodynamic data [Time frame: T1: 30 minutes (min) after spinal anesthesia, T2: at the end of the surgical procedure, T3: at 30 minutes after recovery]
- length of hospital stay [Time frame: day]
