COMPARİSON OF THE EFFECTS OF ULTRASOUND-GUİDED ERECTOR SPİNAE PLANE BLOCK AND INTRAMUSCULAR NONSTEROİDAL ANTİ-INFLAMMATORY DRUG ADMİNİSTRATİON ON INTRAOPERATİVE ANALGESİA AND PATİENT SATİSFACTİON DURİNG EXTRACORPOREAL SHOCK WAVE LİTHOTRİPSY

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.

Stress Ball Effects to Pain, Anxiety, Satisfaction and Treatment Continuity During ESWL

Extracorporeal shock wave lithotripsy (ESWL), a minimally invasive procedure, is used in the treatment of urolithiasis. The shock waves used in this procedure, which does not require any incision, cause pain in the superficial structures of the body such as skin, muscles and deep structures such as costae, nerves and kidney tissue. This pain may cause patients not to tolerate the treatment, delay in recovery, decrease in the effectiveness of the treatment and decrease in satisfaction. Patients may also experience anxiety about the procedure prior to treatment. Anxious patients experience more pain during ESWL. Pain and anxiety increase the activation of the sympathetic nervous system and neuroendocrine response, leading to physiologic changes such as increased blood pressure, heart rate and oxygen requirement of the body. This may negatively affect the vital signs of the patients. Therefore, it is essential to relieve pain and anxiety in patients undergoing ESWL and pharmacologic and nonpharmacologic methods are used for this purpose. Pharmacologic methods such as analgesics, opioids and sedative agents are used to reduce pain and anxiety in patients. Since these methods have side effects such as nausea, vomiting, gastric bleeding, respiratory depression, tachycardia, constipation, the use of non-pharmacological methods that can be applied by nurses is increasing. One of the non-pharmacologic methods is the stress ball, which uses the sense of touch to divert attention with cognitive focus. In this simple, reliable, cheap and easily accessible method, pain and anxiety are reduced by directing the mind to the attention-grabbing stimulus.

Optical Motion Capture-Assisted Ultrasound for Pediatric ESWL

The incidence of pediatric urinary system stones has shown an upward trend in recent years, and Extracorporeal Shock Wave Lithotripsy (ESWL) has become one of the most important minimally invasive treatments for pediatric upper urinary tract stones. Currently, the widely used clinical ultrasound mechanical coupling localization mode suffers from issues such as limited scanning degrees of freedom and difficulty in intuitively grasping the spatial relationship between the stone and the focal point. These issues lead to prolonged stone pre-localization times, significant reliance on operator experience, and a steep learning curve for young and primary care physicians, thereby restricting the standardization and widespread promotion of pediatric ESWL. Building upon existing ESWL equipment, this project independently constructs an "Optical Motion Capture-Assisted Ultrasound Pre-localization System." By utilizing multi-camera infrared motion capture to acquire the 3D pose of the ultrasound probe and the shock wave source in real-time and establishing a unified spatial coordinate system, the system achieves automatic conversion and visual display of the stone's position from the ultrasound image to the shock wave focal point coordinates. This guides the operator to quickly complete focal point pre-localization after freely scanning for the stone. Results from preliminary phantom studies and initial clinical pilot experiments indicate that, while maintaining the routine ESWL workflow, this system can significantly shorten the first effective pre-localization time for pediatric stones from approximately 15 minutes to around 5 minutes, without a significant decrease in the stone clearance rate. This suggests the technology possesses good engineering feasibility and clinical application prospects. This study proposes to conduct a single-center, prospective, single-blind randomized controlled clinical trial. Pediatric patients with upper urinary tract stones eligible for ESWL will be randomly assigned 1:1 to an experimental group and a control group. The experimental group will use the Optical Motion Capture-Assisted Ultrasound Pre-localization System for stone pre-localization, while the control group will use the routine ultrasound mechanical coupling localization method. The \*\*primary outcome measure\*\* is the time to first effective stone pre-localization. \*\*Secondary outcomes\*\* include the stone clearance rate evaluated by imaging at 4 and 12 weeks post-operation, the total number of shock waves released and total energy, total procedure time, intraoperative and postoperative complication rates, sedation/anesthesia dosage, and family satisfaction. Additionally, the study will systematically evaluate the system's impact on physician learning curves and work intensity by analyzing the localization success rate of operators with different seniority levels, learning curves (the trend of localization time versus the number of cases), and subjective workload scores. The core scientific question this project aims to answer is: Under the premise of not compromising the therapeutic efficacy and safety of pediatric ESWL, can optical motion capture-assisted ultrasound pre-localization significantly improve stone localization efficiency, reduce operator workload, and shorten the learning curve for young physicians, thereby enhancing the standardization and accessibility of pediatric ESWL? The expected results will provide an evidence-based foundation for optimizing pediatric ESWL localization modes and formulating relevant technical standards and training programs. Furthermore, it will lay the clinical validation groundwork for future intelligent lithotripsy systems integrating functions such as intelligent identification and robotic arm automatic tracking.
