Clinical trials

Endotracheal intubation may cause significant increases in blood pressure, heart rate, and intracranial pressure, particularly in patients undergoing cerebral aneurysm coil embolization. Remifentanil and esmolol are commonly used agents to attenuate these responses during anesthesia induction. This randomized controlled trial aims to compare the effects of remifentanil and esmolol administered before endotracheal intubation on optic nerve sheath diameter/eyeball transverse diameter ratio (ONSD/ETD), a noninvasive surrogate marker of intracranial pressure, as well as hemodynamic responses in patients undergoing elective cerebral aneurysm coil embolization. The findings may help identify the most effective strategy for minimizing intubation-related intracranial pressure changes and hemodynamic fluctuations in neurointerventional anesthesia practice.

During general anesthesia, the eye's natural protective reflexes are suppressed, which can lead to corneal drying and injury. To prevent this, anesthesiologists routinely tape the eyelids closed. In many centers, lubricant eye drops are also applied in addition to taping, but whether this adds meaningful protection is unclear.This study will compare two approaches to eye protection during general anesthesia lasting 30 minutes to 3 hours: eyelid taping alone versus eyelid taping combined with lubricant eye drops. Two hundred adult patients undergoing elective, non-eye surgery in the supine position will be randomly assigned to one of the two groups.The main outcome is corneal surface damage measured by a standardized fluorescein staining score (NEI scale, 0-15) assessed by a blinded evaluator one hour after surgery. Secondary outcomes include tear film stability (TBUT), tear production (Schirmer test), patient-reported eye symptoms at 2 and 24 hours after surgery, and a cost-effectiveness analysis comparing the two approaches.If taping alone proves equally effective, routine use of lubricant eye drops may be unnecessary, reducing costs without compromising patient safety.

HA therapy typically consists of several intra-articular injections administered at weekly intervals. A single-dose IA-HA treatment offers patients and physicians a treatment option that involves both lower costs and fewer clinic visits. Furthermore, considering the administration procedure, we believe that single-dose therapy helps reduce the risk of potential side effects. In light of this information, our study aims to retrospectively evaluate the efficacy and safety of HA in patients with symptomatic knee OA who have received a single-dose intra-articular HA injection.

This study shows that in craniotomy patients using a skull pin head holder, an ultrasound-guided scalp block reduces perioperative opioid consumption, improves hemodynamic stability, and decreases the inflammatory response.

Obesity is associated with anatomical changes in the upper airway that increase the risk of difficult laryngoscopy and difficult mask ventilation during anesthesia. Conventional airway assessment parameters such as Mallampati score, neck circumference, and STOP-BANG scale are widely used but have limited predictive accuracy in obese patients. Airway ultrasonography has emerged as a promising non-invasive tool for difficult airway prediction; however, ultrasonographic criteria have not yet been standardized. This prospective observational study aims to evaluate the utility of airway ultrasonography in predicting difficult airway in adult obese patients (BMI \>30 kg/m²) scheduled for elective surgery under general anesthesia. Ultrasonographic measurements will include the distance from skin to hyoid bone (DSHB) at the level of the hyoid bone, the anterior neck soft tissue thickness at the thyrohyoid membrane level, and the hyomental distance ratio (HMDR). These parameters will be compared with conventional airway assessment tools and correlated with intraoperative Cormack-Lehane laryngoscopy grade and Han Scale mask ventilation score to determine their predictive value for difficult airway.

This study evaluates laryngeal edema in ICU patients during weaning from mechanical ventilation. It compares the cuff leak test and ultrasound-based laryngeal air column measurements in predicting weaning success. Ultrasound offers a non-invasive and real-time alternative for airway assessment. The study also examines post-extubation complications such as stridor, sore throat, dysphonia, and dysphagia.

This study aims to evaluate the effectiveness of magnetotherapy in the treatment of lateral epicondylitis (tennis elbow). Lateral epicondylitis is a common musculoskeletal condition characterized by pain and tenderness over the outer part of the elbow, often associated with repetitive wrist extension and gripping activities. It may cause reduced grip strength, functional limitations, and decreased quality of life. In this prospective, randomized, double-blind, sham-controlled clinical trial, 40 patients aged 18-65 years diagnosed with lateral epicondylitis will be enrolled. Participants will be randomly assigned into two groups using the sealed envelope method. The experimental group will receive active magnetotherapy in addition to standard treatment (local application and supervised exercise therapy). The control group will receive sham magnetotherapy (inactive device without magnetic field) plus the same standard treatment. Treatments will be administered five days per week for three weeks. Magnetotherapy will be applied at a frequency of 50 Hz and intensity of 85 Gauss for 30 minutes per session. All participants will also receive 15 minutes of local application and 15 minutes of supervised exercises including eccentric wrist extensor exercises, isotonic strengthening, stretching, and isometric exercises. Outcomes will be evaluated at baseline (week 0), at the end of treatment (week 3), and at follow-up (week 12). Primary and secondary outcome measures include pain intensity (Visual Analog Scale), pressure pain threshold (algometer), grip strength (hand dynamometer), functional status (PRTEE and QuickDASH questionnaires), quality of life (SF-36), clinical provocation tests (Cozen, Mill's, and Maudsley's tests), and patient satisfaction (Likert scale). The study hypothesis is that adding magnetotherapy to standard treatment will provide additional benefit in reducing pain and improving function compared to standard treatment alone.

Postoperative pain remains a significant clinical problem affecting recovery, mobilization, and patient satisfaction after surgery. Considerable interindividual variability exists in postoperative pain intensity even among patients undergoing the same surgical procedure. This variability may be influenced not only by the extent of surgical trauma but also by individual pain sensitivity and psychological factors such as preoperative anxiety. The aim of this prospective observational study is to evaluate whether pain intensity reported during routine venous cannulation and preoperative anxiety levels assessed by the Amsterdam Preoperative Anxiety and Information Scale (APAIS) can predict early postoperative pain severity in patients undergoing elective laparoscopic cholecystectomy under general anesthesia. Venous cannulation pain will be assessed using a 0-10 visual analog scale (VAS), and anxiety levels will be measured preoperatively using APAIS. Postoperative pain will be evaluated at predefined time points within the first 12 hours after surgery using VAS scores and analgesic consumption. Identifying simple and easily obtainable preoperative predictors may allow individualized postoperative analgesic strategies for patients at higher risk of severe postoperative pain.

In this study, the effects of Kinesio Taping methods applied in combination with Schroth therapy on pain and functional capacity in young adults diagnosed with idiopathic scoliosis will be evaluated. This study is designed as a randomized controlled trial. Participants will be randomly assigned to one of three groups: Group 1: Schroth therapy combined with Kinesio Taping Group 2: Schroth therapy alone Group 3: Schroth therapy combined with sham Kinesio Taping Kinesio Taping will be applied for 4 weeks. The tape will remain in place for 5 consecutive days, followed by a 2-day rest period for the skin, and this cycle will be repeated throughout the intervention period. Schroth therapy will be administered 3 times per week for 4 weeks. Assessments will be conducted at baseline (Week 0), during treatment (Week 2), at the end of treatment (Week 4), and at follow-up (Week 8). The primary outcome measures will be pain intensity assessed by the Numeric Rating Scale (NRS) and functional disability assessed by the Oswestry Disability Index (ODI). Secondary outcome measures will include the Scoliosis Research Society-22 (SRS-22) questionnaire and the Patient Global Impression of Change (PGIC) scale.

This study is designed to investigate the effectiveness of low-frequency pulsed electromagnetic field therapy in individuals diagnosed with mild-to-moderate carpal tunnel syndrome (CTS). This double-blind, randomized controlled trial will randomly assign participants into three groups: Group 1: Active magnetotherapy Group 2: Placebo magnetotherapy (treatment using an identical device that does not generate a magnetic field) Group 3: Routine (conservative) treatment group All participants will receive a standard nighttime wrist splint and a standardized nerve and tendon gliding exercise protocol. Magnetic field applications will be administered five days per week for a total of 15 sessions. Assessments will be conducted at baseline (T0), at the end of treatment (T1 - Week 3), at 1 month (T2), and at 3 months (T3). The primary outcome measures include the Boston Carpal Tunnel Questionnaire (BCTQ), pain intensity assessed by the Visual Analog Scale (VAS), functional status measured by QuickDASH, median nerve cross-sectional area assessed by ultrasonography, sensory function evaluated using the Semmes-Weinstein monofilament test, grip strength measured by dynamometry, and clinical test results (Tinel and Phalen tests). Secondary outcomes include sleep quality assessed by the Pittsburgh Sleep Quality Index (PSQI) and patient satisfaction. This study aims to contribute to the scientific evidence regarding the effectiveness of magnetotherapy as a non-invasive treatment option for carpal tunnel syndrome.

In this study, the validity and reliability of the Hypertonia Assessment Tool (HAT), which has previously been validated in the pediatric cerebral palsy (CP) population, will be evaluated in adult individuals who have experienced a stroke. The HAT is a specific clinical instrument designed to differentiate subtypes of hypertonia, including spasticity, dystonia, and rigidity. Accurate classification of hypertonia subtypes following stroke is crucial for guiding rehabilitation strategies. However, the HAT has not yet been validated in the adult post-stroke population. This study will be conducted at the Physical Medicine and Rehabilitation Clinic of SBU Fatih Sultan Mehmet Training and Research Hospital. The study aims to evaluate the validity and reliability of the HAT for use in adults with stroke.

This prospective observational study aims to evaluate the effect of ultrasound-guided Quadro-Iliac Plane Block (QIPB) on postoperative analgesia in patients undergoing lumbar spinal surgery. Lumbar spinal procedures are commonly associated with significant postoperative pain, which may impair early mobilization and increase opioid consumption. In routine clinical practice, QIPB is increasingly used as part of multimodal analgesia to improve pain control and reduce opioid-related adverse effects. Adult patients scheduled for elective lumbar spinal surgery under general anesthesia will be followed according to routine clinical care. Postoperative analgesia will be managed with intravenous patient-controlled analgesia (PCA) using tramadol, with or without the addition of ultrasound-guided QIPB, based on the preference of the attending anesthesiologist. No intervention or treatment assignment will be performed by the investigators. Postoperative pain scores at rest and during movement, opioid consumption, need for rescue analgesics, incidence of nausea and vomiting, and patient satisfaction will be recorded during the first 24 hours after surgery. The findings of this study are expected to provide further clinical evidence regarding the effectiveness of QIPB as part of multimodal analgesia in lumbar spinal surgery.

This study aims to evaluate whether guidance by the Oxygen Reserve Index (ORi) improves inspiratory oxygen fraction (FiO₂) titration compared with conventional pulse oximetry (SpO₂)-guided oxygen administration in adult patients undergoing surgery in the beach chair position. Oxygen therapy is routinely used during general anesthesia to prevent hypoxemia; however, excessive oxygen administration may result in hyperoxia, which has been associated with adverse cardiovascular and pulmonary effects. Standard pulse oximetry may not adequately detect hyperoxia when oxygen saturation values are high. In this prospective comparative study, patients will receive oxygen titration guided either by SpO₂ alone or by combined ORi and SpO₂ monitoring. The primary outcome is the incidence of intraoperative hyperoxemia, assessed by arterial blood gas analysis. Secondary outcomes include intraoperative oxygenation parameters and hemodynamic variables.

This prospective observational study aims to evaluate the effects of ultrasound-guided ankle block on sensory and motor block characteristics and postoperative analgesic outcomes in patients undergoing lower extremity surgery. The study will compare diabetic and non-diabetic patients and will also assess the impact of glycemic control on block onset time and postoperative analgesic consumption. Ankle block is commonly used in patients undergoing foot and ankle surgery, particularly in those with diabetes, peripheral neuropathy, or vascular disease, when general or neuraxial anesthesia may not be suitable. Previous studies suggest that diabetic neuropathy and impaired glycemic control may influence the onset and duration of peripheral nerve blocks. Adult patients scheduled for lower extremity surgery under ankle block will be included. All procedures will be performed as part of routine clinical care, and no additional interventions will be applied for research purposes. Sensory and motor block onset times, postoperative pain scores, opioid consumption within the first 24 hours, and patient and surgeon satisfaction will be recorded. The results of this study are expected to provide clinically relevant information regarding the effects of diabetes and glycemic control on ankle block characteristics and postoperative analgesia.

The purpose of this prospective randomized controlled clinical trial is to evaluate the effect of suprascapular nerve block on shoulder joint proprioception in stroke patients with hemiplegic shoulder pain. Fourteen patients aged 18-80 years with hemiplegic shoulder pain will be randomized into two groups. One group will receive suprascapular nerve block followed by a standardized physical therapy program, while the control group will receive the same physical therapy program alone. The primary outcome is shoulder joint proprioception. Secondary outcomes include pain intensity, shoulder range of motion, motor recovery, stroke-specific quality of life, and upper extremity functional outcomes. The results of this study are expected to clarify the role of suprascapular nerve block on proprioception and rehabilitation outcomes in patients with hemiplegic shoulder pain.

Shoulder pain is the third most common musculoskeletal pain complaint in the world with an incidence of 7-30%. Subacromial impingement syndrome (SIS) is the most common cause of shoulder pain. Imaging in impingement syndrome is usually based on different imaging modalities. X-ray, magnetic resonance imaging (MRI) and ultrasound are the most commonly used, and MRI is considered by many authors to be the most reliable imaging modality for evaluation of the rotator cuff because it allows evaluation of soft tissues as well as bony abnormalities such as subacromial osteophytes and acromioclavicular joint capsular hypertrophy. MRI allows the diagnosis of rotator cuff tears with greater interobserver reliability than ultrasound in assessing tear size, retraction and atrophy. Few studies have investigated the impact of pathologic findings on MRI on the degree of symptoms and functional impairment seen in these patients. The aim of this study was to investigate the relationship between shoulder pain and function and MRI findings in patients with subacromial impingement syndrome.
