Brief summary
Does adding Dexamethasone to the Periarticular Nerve Group Block in Patients undergoing Total Hip Arthroplasty reduce the dose of ropivacaine?
Detailed description
Hip arthroplasty is one of the most common orthopaedic procedures, especially in elderly patients, due to the deformation of joints. Patients may complain of severe pain due to surgical trauma and prostheses. Regional anaesthesia methods may be performed to reduce the inflammatory response, opioid consumption, and opioid-related side effects.
Interventions
DRUGRopivacaine
Ultrasound-guided PENG block - 20ml 0,2% ropivacaine
Ultrasound-guided PENG block - 10ml 0,2% ropivacaine + 4mg Dexamethasone

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time to first rescue opioid analgesia | 48 hours after surgery | Time after surgery when the patient needs opiate for the first time |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Numerical Rating Scale [range 0:10] | 4 hours after surgery | Postoperative pain assessment will be performed using the NRS score (0 = no pain, 10 = the most severe pain felt) |
| Quadriceps muscle strength assessed using medical research council scale [range 0:5] | 4 hours after surgery | Quadriceps muscle strength (knee extension and hip adduction) will be evaluated according to the medical research council muscle strength rating |
| Nerve damage [range 0-4] | 12 hours after surgery | Nerve damage assesment will be performed using the nerve damage score (N0- no nerve damage; N1- minor - sensory paresthesia; N2- major -complete sensory anesthesia; N3- Complete- complete motor defect with or without paraesthesia; N4-CRPS- Complex Regional Pain Syndrome) |
| Total Opioid Consumption | 48 hours after surgery | Total opiate consumption after surgery |
| NLR | 12 hours after surgery | neutrophile-to-lymphocyte ratio |
| PLR | 12 hours after surgery | platelet-to-lymphocyte ratio |
| glucose | 24 hours after surgery | blood glucose level |
