COMPARISON OF THE EFFECTS OF ULTRASOUND-GUIDED ERECTOR SPINAE PLANE BLOCK AND INTRAMUSCULAR NONSTEROIDAL ANTI-INFLAMMATORY DRUG ADMINISTRATION ON INTRAOPERATIVE ANALGESIA AND PATIENT SATISFACTION DURING EXTRACORPOREAL SHOCK WAVE LITHOTRIPSY

The aim of this study is to compare two ways of reducing pain during extracorporeal shock wave lithotripsy (ESWL), a non-invasive treatment that breaks up kidney and urinary stones with shock waves. Many patients find ESWL painful. In this study, adult patients (18-60 years, ASA I-II) scheduled for ESWL are randomly assigned to one of three groups: (1) an ultrasound-guided erector spinae plane block (ESPB), an injection of local anesthetic near the spine on the side of the treated kidney; (2) an intramuscular injection of the anti-inflammatory painkiller diclofenac sodium before the procedure; or (3) no pain medication before the procedure (control). The main question is whether ESPB lowers pain scores during ESWL more than intramuscular diclofenac. Secondary questions include heart rate and blood pressure stability, the need for painkillers after the procedure, and patient satisfaction.
