Clinical trials

The goal of this clinical trial is to compare the effects of flow-controlled ventilation (FCV) and volume-controlled ventilation (VCV) on hemodynamic and respiratory parameters in obese patients undergoing elective laparoscopic bariatric surgery. The main questions it aims to answer are: Does FCV provide better intraoperative hemodynamic and respiratory stability compared to VCV during laparoscopic bariatric surgery? Is FCV a safe and feasible ventilation strategy under high intraabdominal pressure and position changes required in bariatric surgery? Researchers will compare FCV group to VCV group to see if FCV improves intraoperative respiratory mechanics and hemodynamic parameters. Participants will: Undergo elective laparoscopic bariatric surgery with BMI \>40 kg/m² (ASA I-III) Receive either flow-controlled or volume-controlled ventilation with individualized PEEP and tidal volume of 6-8 ml/kg predicted body weight Have intraoperative hemodynamic and respiratory parameters monitored at regular intervals, including arterial blood gas analysis Be followed postoperatively for oxygen therapy requirement and intensive care need

This prospective observational study aims to compare the clinical effectiveness of perineural 5% dextrose injections and perineural local anesthetic injections in patients with symptomatic knee osteoarthritis. Adult patients receiving routine perineural injection therapy will be followed for six months. Pain intensity and functional outcomes will be assessed at baseline and at 1, 3, and 6 months after treatment using validated clinical assessment tools.

Forward Head Posture Frequency in Fibromyalgia Patients Assessed by Craniovertebral Angle: Association with Symptom Severity. Forward head posture is more common in patients with fibromyalgia and is a factor that increases symptom severity.

The purpose of the study is to reveal whether there are concurrent shoulder lesions in patients with hand injuries. Its importance is that it will shed light on whether not only the hand but also the shoulder should be included in the treatment program in hand rehabilitation.

Holmium Laser Enucleation of the Prostate (HoLEP) is an increasingly popular endoscopic minimally invasive surgical technique for the treatment of benign prostatic hyperplasia (BPH). In the literature, the long-term efficacy and low complication rates of HoLEP have been highlighted in many studies. However, in the early postoperative period, particularly within the first three months, irritative symptoms are reported in 17-35% of cases (1-2). The pathophysiology of postoperative irritative symptoms is not yet fully understood, but it has been suggested that these symptoms may be associated with urethral trauma, the mucosal healing process, and detrusor overactivity. These symptoms can significantly impact quality of life, reducing patient satisfaction. In particular, dysuria is a frequently encountered symptom after HoLEP, with considerable individual variability in its severity and duration. The effectiveness of alpha-blockers in alleviating postoperative dysuria and irritative symptoms remains a topic of debate in the literature. Although prostate tissue is surgically removed, alpha-blockers may improve urinary flow and relieve symptoms associated with bladder outlet obstruction by reducing urethral smooth muscle tone (3). Studies on the use of alpha-blockers following transurethral resection of the prostate (TURP) have shown limited postoperative benefits (4). However, to the best of our knowledge, no study has specifically evaluated their use following HoLEP, an enucleation-based technique. Therefore, further studies are needed to assess the role of alpha-blockers in managing dysuria after HoLEP. The aim of this study is to evaluate the effectiveness of alpha-blocker therapy in managing dysuria and other irritative symptoms following HoLEP. Additionally, the study seeks to determine the impact of this treatment on quality of life and patient satisfaction.
