Clinical trials

The goal of this clinical trial is to evaluate the clinical efficacy of different doses of intra-articular ozone injections combined with exercise in patients aged 40-75 diagnosed with Grade 2-3 knee osteoarthritis. The main questions it aims to answer are: * Which intra-articular ozone doses (10 µg/mL, 15 µg/mL, or 20 µg/mL) is most effective in improving pain and physical function in knee osteoarthritis? * Do combined ozone and exercise therapies provide superior clinical outcomes compared to exercise therapy alone? Researchers will compare four groups (Ozone 10 µg/mL + Exercise, Ozone 15 µg/mL + Exercise, Ozone 20 µg/mL + Exercise and Exercise Alone) to see the dose-dependent effects of ozone therapy. Participants will: * Complete a structured home exercise program for the duration of the study. * Receive 3 sessions of intra-articular ozone injections (for patients allocated to the ozone groups). * Participate follow-up visits for clinical and functional assessments at baseline (before the procedure), immediately after the 3rd injection session, at 1 month after the last ozone injection, and at 3 months after the last ozone injection.

This prospective, randomized, controlled clinical trial aims to compare the effects of two ultrasound-guided fascial plane blocks, the Erector Spinae Plane Block (ESPB) and the Modified Thoracoabdominal Nerve Block through Perichondrial Approach (M-TAPA), on postoperative pulmonary function and analgesic consumption in patients undergoing laparoscopic cholecystectomy. Laparoscopic cholecystectomy is one of the most frequently performed abdominal surgical procedures worldwide. Despite minimally invasive techniques, postoperative pain remains a significant clinical problem due to port-site trauma, pneumoperitoneum, diaphragmatic irritation, and visceral manipulation. Inadequate pain control may lead to impaired respiratory mechanics, reduced mobilization, delayed recovery, and an increased risk of postoperative pulmonary complications. Postoperative pulmonary dysfunction is a common consequence of upper abdominal surgery and may persist for several days, contributing to reductions in forced vital capacity (FVC) and forced expiratory volume in one second (FEV1), which are associated with increased postoperative morbidity. Although opioid-based analgesia is widely used, it is associated with adverse effects such as respiratory depression, nausea, vomiting, ileus, and delayed recovery. Therefore, regional anesthesia techniques and multimodal analgesia strategies are increasingly recommended to reduce opioid consumption while improving pain control. ESPB and M-TAPA are ultrasound-guided fascial plane blocks used for postoperative analgesia in abdominal surgery. ESPB provides somatic and visceral analgesia through the spread of local anesthetic affecting the spinal nerve rami, while M-TAPA targets the anterior branches of the thoracoabdominal nerves to provide extensive anterior and lateral abdominal wall analgesia. Despite their increasing use, there is limited high-quality comparative evidence evaluating the effects of ESPB and M-TAPA on postoperative pulmonary function and opioid consumption in laparoscopic cholecystectomy. This study compares these two regional anesthesia techniques in a randomized controlled design to evaluate their impact on postoperative respiratory function and analgesic requirements.

This study aims to evaluate the effect of Conox (qCON/qNOX)-guided anesthesia on intraoperative anesthetic drug consumption and postoperative outcomes in pediatric patients undergoing adenotonsillectomy. Conox is a non-invasive EEG-based monitoring system that provides indices of both hypnosis and nociception. In this randomized controlled trial, children aged 3-12 years will be assigned to either a Conox-guided anesthesia group or a standard monitoring group. The primary outcome of the study is total intraoperative opioid consumption, assessed from anesthesia induction to the end of surgery. Secondary outcomes include emergence time, extubation time, postoperative agitation, pain scores, and correlation between qCON/qNOX values and hemodynamic parameters.

Several studies have demonstrated that inhalational anesthetic agents such as desflurane and sevoflurane may cause varying degrees of postoperative sore throat, hoarseness, and cough in orotracheally intubated patients. However, data evaluating these outcomes under low-flow anesthesia conditions remain limited and insufficient. This single-center, prospective, randomized controlled study will be conducted in patients aged 18-65 years, classified as American Society of Anesthesiologists (ASA) physical status I-II, who are scheduled to undergo elective laparoscopic cholecystectomy under general anesthesia and who provide written informed consent to participate in the study. The primary objective of the study is to compare the effects of low-flow desflurane and low-flow sevoflurane anesthesia on the incidence and severity of postoperative sore throat. The secondary outcomes include the evaluation of postoperative hoarseness and cough, the incidence of postoperative nausea and vomiting (PONV), and the total consumption of inhalational anesthetic agents.

This prospective randomized study will compare the effects of Erector Spinae Plane Block (ESPB) and Serratus Anterior Plane Block combined with Pectoral Nerve Block Type II (SAPB + PECS II) on intraoperative analgesia and postoperative opioid consumption in patients undergoing breast cancer surgery. Seventy patients (ASA I-III, aged 18-75 years) will be randomized into two groups using the sealed envelope method. Ultrasound-guided blocks will be performed preoperatively by the same anesthesiologist, with Group 1 receiving ESPB and Group 2 receiving a combined SAPB + PECS II technique performed through a single skin puncture (single needle entry site) with sequential injections into the two target fascial planes. All patients will undergo surgery under general anesthesia and receive postoperative analgesia via morphine patient-controlled analgesia. Pain scores and total opioid consumption will be statistically analyzed, with p \< 0.05 considered significant.

The aim of this study is to evaluate the effect of using the non-invasive Conox monitor on intraoperative opioid consumption. Additionally, the study aims to assess the impact of Conox monitoring on recovery time, postoperative agitation rate, and pain scores, and to investigate the correlation between qCON and qNOX values and conventional hemodynamic parameters.

This study aims to evaluate the diagnostic accuracy of ultrasonographic measurements of the median nerve in patients with Carpal Tunnel Syndrome (CTS). While ultrasound is a common diagnostic tool, various physical factors can influence its results. The researchers will investigate how a patient's absolute body weight and Body Mass Index (BMI) affect the size of the median nerve cross-sectional area across different stages of disease severity. The goal is to determine if absolute body weight plays a 'masking' role that could lead to more precise diagnostic interpretations in clinical practice.

The aim of this observational study is to evaluate the diagnostic value of multimodal ultrasonography in differentiating between lymphedema and lipedema. Differentiating these two chronic conditions based solely on clinical examination can be challenging due to overlapping symptoms. This study will utilize various non-invasive ultrasound techniques-including B-mode ultrasound, strain elastography, power Doppler, and quantitative ImageJ analysis-to compare tissue characteristics among patients with lymphedema, patients with lipedema, and healthy controls. The goal is to identify reliable, non-invasive imaging biomarkers that can facilitate early and accurate diagnosis, thereby optimizing patient management.

The aim of this study is to compare the Osteoporosis Risk Assessment Tool and the Osteoporosis Self-Assessment Tool with the gold standard DEXA in determining the risk of osteoporosis in the lumbar and femoral regions in female individuals in the Turkish population, and to investigate their sensitivity and specificity in the first stage of screening for the detection of female osteoporosis.

Obesity is classified using body mass index (BMI) (BMI ≥25 overweight, BMI ≥30 obese, BMI ≥40 morbidly obese). Obese patients are Class 1 according to BMI; BMI:30-34.9 and Class 2; BMI: It is classified as 35-39.9. Patients with classes 1 and 2 will be included in the study. Obesity can be accompanied by comorbidities such as atherosclerotic vascular and cardiac pathologies, hyperlipidemia, hypertension, coronary artery disease, diabetes mellitus, so obesity treatment should be managed multidisciplinary. The basic approach to obesity treatment is diet, exercise, medical treatment, treatment of comorbid conditions and surgery. Aerobic exercise therapy, which is one of the conservative approaches in the treatment of obesity, also has an important place in the treatment of cardiovascular diseases associated with obesity. Atherosclerotic cardiovascular disease (AKD) is one of the most important causes of morbidity and mortality worldwide. Negative changes in functional capacity, quality of life and psychosocial situations are observed due to disorders associated with this disease. Physical activity is among the modifiable risk factors in atherosclerotic diseases. However, patients have a fear of movement related to angina-like symptoms, with the thought that the symptoms may recur during exercise. Lack of physical activity due to fear of movement leads to obesity, which in turn leads to aggravation of atherosclerosis and an increase in the incidence of cardiovascular events, which negatively affects individual and psychosocial capacity. Cardiopulmonary exercise test (CPET) is a non-invasive procedure that evaluates the individual's capacity during dynamic exercise and provides diagnostic and prognostic information. CPET is based on the investigation of the respiratory system, cardiovascular system and cellular response to exercise performed under controlled metabolic conditions. It allows holistic evaluation of the response to exercise, including not only the pulmonary and cardiovascular systems but also the musculoskeletal system. Fear of movement or kinesiophobia; It is defined as a state of fear and avoidance of activity and physical movement resulting from the feeling of sensitivity to painful injury and repeated injury.
