Clinical trials

The goal of this observational study is to learn whether a participant's understanding of the informed consent information is related to the amount of propofol needed during endobronchial ultrasound (EBUS). EBUS is a procedure that uses a thin camera and ultrasound to look at lymph nodes and other areas inside the chest. Propofol is a sedative medicine used to help participants stay comfortable during the procedure. Before EBUS, all participants will receive the usual information about the procedure as part of routine care. After this routine consent process, participants will answer short questions about what they understood. They will also answer questions about their anxiety before the procedure. The study will not change the usual consent process, sedation plan, or medical care. During EBUS, participants will receive usual sedation and monitoring according to routine clinical practice. The research team will record how much sedative medicine is used, whether extra sedation is needed, whether any important clinical events occur, and how participants recover after sedation. The main question is whether participants who understand the consent information better need less propofol during EBUS.

The aim of this study will be to examine the relationship between leg muscle mass and muscle strength, aerobic capacity, anaerobic power, and jumping performance in young adults. In addition, these physical performance measures will be compared between male and female participants. Recreationally active young adults will be recruited to participate in the study. Body weight and leg muscle mass will be assessed using a body composition analyzer. Participants will perform isokinetic and isometric leg strength tests, an aerobic fitness test (VO₂max), an anaerobic power test (Wingate), and a countermovement jump (CMJ) test. This study aims to improve the understanding of the effects of leg muscle mass on physical performance and to identify possible differences between males and females. The findings are expected to contribute to exercise prescription, performance assessment, and future research in sports and health sciences.

Protocols are being developed and implemented to ensure the best possible recovery process for patients undergoing transsphenoidal surgery, and their impact on patient outcomes is being evaluated. In studies where perioperative protocols-including patient education (verbal and written instruction on dehydration, hyponatremia, adrenal insufficiency, CSF leakage, meningitis, and the signs and symptoms of visual or other neurological disorders)-are implemented, it has been reported that patients' length of hospital stay is reduced, the rate of patients experiencing hyponatremia has decreased, and readmissions have declined (Sanchez-Garavito et al., 2024; Sarris et al., 2021). However, since these studies included protocols covering the entire surgical process-not just patient education-it is difficult to determine whether changes in patient outcomes stem from patient education or from alterations in other parameters within the protocol. Therefore, in the clinic where this study will be conducted, the effect of patient education on postoperative patient outcomes will be examined by developing an educational material that standardizes patient education, without making any changes to the surgical or pharmacological processes.

Falls are common in patients with Parkinson disease and may lead to reduced mobility, fear of falling, loss of independence, and injury. Exercise-based rehabilitation programs may help improve balance, gait, and physical performance in this population. This randomized controlled trial aims to compare the effectiveness of two home-based exercise programs in patients with Parkinson disease: the Otago Exercise Program and a structured home exercise program. Participants will be randomly assigned to one of two groups. Both groups will receive exercise education and will perform their assigned home exercise program for 6 weeks. Participants will be evaluated at baseline, at week 3, and at the end of week 6. The study will assess fall-related outcomes, freezing of gait, functional mobility, gait parameters, postural control, and physical performance. The results may help determine which home-based exercise approach is more effective for reducing fall risk and improving functional outcomes in patients with Parkinson disease.

This study will be conducted to determine the relationship between the perception of safety culture among healthcare professionals working in an outpatient surgical unit and the level of safety patients feel during surgery performed under local anesthesia. The study population consists of healthcare professionals (N = 140) working in the Day Surgery Unit of Bursa Uludağ University Faculty of Medicine Hospital and patients undergoing procedures. The sample size calculation for the healthcare professionals to be included in the study was determined using the known population sampling method. Using the Raosoft sampling method, with a 5% margin of error and a 95% confidence interval, the minimum required sample size (n) was calculated to be 103. It was decided that the study would include healthcare professionals and patients in a 1:1 ratio. Therefore, the total sample size was calculated to be 206. Data will be collected using the Hospital Survey on Patient Safety Culture (Version 2.0) and the Feeling Safe During Surgery Scale.

This randomized controlled clinical trial aims to investigate the effects of whole-body vibration (WBV) exercises combined with balneotherapy on pain, physical function, sleep quality, and daily activity levels in individuals with chronic low back pain. A total of 60 volunteers aged 18 to 65 who have been diagnosed with chronic low back pain by a physical medicine and rehabilitation specialist and who meet the eligibility criteria will be included. Participants will be randomly assigned to two groups. Both groups will receive balneotherapy five days a week for three weeks. After balneotherapy, the first group will perform standard stretching, strengthening, and aerobic exercises designed for low back pain. The second group will receive the same exercise program in combination with WBV exercises using a vibration platform. WBV sessions will include static and dynamic exercises with specific frequency and amplitude settings. All participants will be evaluated at baseline and after three weeks using validated measures, including pain intensity (Visual Analog Scale), spinal mobility (Modified Schober Test), balance and reach (Functional Reach Test), physical performance (Sit-to-Stand and Timed Up and Go Tests), disability (Oswestry Disability Index, Roland-Morris Questionnaire), and sleep quality (Pittsburgh Sleep Quality Index). The study seeks to determine whether combining WBV with balneotherapy can provide additional benefits over standard exercise alone in managing chronic low back pain.

Respiratory distress syndrome (RDS) is a common cause of respiratory failure in preterm infants and is frequently treated with surfactant therapy. With the increasing use of noninvasive ventilation, less invasive methods of surfactant administration have been developed. In the technique known as Less Invasive Surfactant Administration (LISA), surfactant is delivered into the trachea through a thin catheter, without the need for endotracheal intubation. This approach may reduce lung injury and improve respiratory outcomes in spontaneously breathing preterm infants. This multicenter, prospective, randomized study aims to compare the clinical effectiveness of poractant alfa and calfactant when administered using the LISA technique in preterm infants born at less than 30 weeks' gestation with RDS who are not intubated. The study will evaluate short-term outcomes, including the need for intubation, repeat surfactant administration, and respiratory support during the first 72 hours of life, as well as longer-term outcomes such as bronchopulmonary dysplasia and other neonatal morbidities.

Newborns with mild hypoxic-ischemic encephalopathy usually do not receive cooling treatment. However, some of these newborns may develop neurological problems later in life. This observational study aims to evaluate whether early brain monitoring and measurements of brain oxygen levels are associated with neurological outcomes in newborns with mild hypoxic-ischemic encephalopathy. Newborns will be monitored during the first 72 hours after birth as part of routine clinical care. Neurological assessments will be performed during early infancy and later follow-up. The findings of this study may help improve early risk assessment and support closer monitoring of newborns who may be at increased risk for unfavorable neurological outcomes.

The aim of this observational study is to investigate whether functional maturation assessment by electroencephalography in preterm infants can provide reliable data for the safe discontinuation of caffeine therapy without recurrence of apnea. In preterm infants receiving caffeine therapy, an assessment of maturation will be performed by EEG at the time when discontinuation of caffeine treatment is planned.

Venipuncture is one of the most common invasive procedures in children and is often associated with significant pain, fear, and anxiety.This randomized controlled study will aim to evaluate the effects of a video game-based breathing exercise intervention on pain, fear, and anxiety levels in children aged 7-12 years undergoing routine venipuncture. While the intervention group will receive a video game-based breathing exercise using the BREATHING+ system in addition to standard care, the control group will receive routine venipuncture procedures only. The study population will consist of children aged 7-12 years who meet the inclusion criteria and whose parents/legal guardians provide informed consent. Participants will be randomly assigned to intervention and control groups. Pain, fear, and anxiety levels will be assessed at three time points: before the procedure, during the procedure, and immediately after the procedure. Data will be collected using the Visual Analog Scale (VAS), Children's Anxiety Scale-State (CAS-S), and Children's Fear Scale (CFS), along with a structured questionnaire form. All assessments will be conducted at the predefined time points.

This study aims to evaluate and compare the analgesic efficacy of two ultrasound-guided regional anesthesia techniques, the serratus anterior plane (SAP) block and the serratus posterior superior intercostal plane (SPSIP) block, in patients undergoing elective mastectomy surgery. Postoperative pain following mastectomy is a common and significant clinical problem that negatively affects patient comfort, delays mobilization, and may prolong hospital stay. Although systemic analgesics are commonly used, they are associated with adverse effects such as sedation, constipation, and potential dependency. In this randomized clinical study, female patients aged 18-75 years with ASA physical status I-III scheduled for elective mastectomy will be included after obtaining informed consent. Patients will be allocated into two groups to receive either SAP block or SPSIP block under ultrasound guidance prior to surgery. Standardized general anesthesia and perioperative analgesia protocols will be applied to all patients. The primary objective is to compare postoperative pain scores between the two groups using the Numeric Rating Scale (NRS). Secondary outcomes include time to first analgesic requirement, total analgesic consumption, intraoperative opioid use, and hemodynamic parameters. By comparing these two interfascial plane blocks, this study aims to identify a more effective analgesic technique that improves postoperative pain control, enhances patient comfort, and facilitates early mobilization following mastectomy.

This study aims to compare the effectiveness of two regional anesthesia techniques in managing pain for participants undergoing cardiac surgery via sternotomy. The investigators will evaluate whether the Erector Spinae Plane Block (ESPB) or a combination of the Superficial Parasternal Intercostal Plane Block (SPIPB) and Serratus Anterior Plane Block (SAPB) provides better pain control and recovery outcomes.

Postoperative pulmonary dysfunction is frequently observed after laparoscopic abdominal surgery due to the combined effects of general anesthesia, pneumoperitoneum, diaphragmatic dysfunction, and postoperative pain. These factors may impair respiratory mechanics, reduce lung volumes, and negatively affect postoperative recovery. Effective postoperative analgesia plays a crucial role in preserving respiratory function by allowing adequate ventilation and reducing pain-related respiratory limitation. The erector spinae plane (ESP) block is a relatively novel ultrasound-guided fascial plane block that provides thoracoabdominal analgesia through the spread of local anesthetic along the paraspinal fascial planes. By reducing postoperative pain and opioid consumption, ESP block may contribute to improved respiratory mechanics and preservation of postoperative pulmonary function. The aim of this prospective randomized controlled study is to evaluate the effect of ultrasound-guided erector spinae plane block on postoperative respiratory function and pain in patients undergoing elective laparoscopic cholecystectomy. Patients will be randomized into two groups: an ESP block group receiving bilateral ultrasound-guided erector spinae plane block and a control group receiving standard analgesic management. Postoperative respiratory parameters will be evaluated using spirometry measurements including forced expiratory volume in one second (FEV1), forced vital capacity (FVC), the FEV1/FVC ratio, and forced expiratory flow at 25-75% of the pulmonary volume (FEF25-75). In addition, arterial blood gas parameters and postoperative pain scores will be assessed and compared between the groups. The study aims to determine whether ultrasound-guided erector spinae plane block improves postoperative respiratory function and contributes to better postoperative recovery in patients undergoing laparoscopic cholecystectomy.

Background and Purpose: Median sternotomy is the standard surgical approach for cardiac procedures, yet it is associated with significant postoperative pain. Inadequate pain management can lead to pulmonary complications and chronic pain syndromes. While opioids are a cornerstone of multimodal analgesia, their side effects-such as sedation, respiratory depression, and nausea-can delay recovery. Furthermore, neuraxial techniques like epidural analgesia are often avoided in cardiac surgery due to the risks associated with systemic heparinization. This study aims to compare the efficacy of two non-neuraxial regional anesthesia techniques: the combination of Transversus Thoracic Plane Block (TTPB) and Serratus Anterior Plane Block (SAPB) versus the Erector Spinae Plane Block (ESPB). Study Design and Population: This prospective, randomized study includes 50 patients (ASA I-III, aged 18-80) undergoing elective cardiac surgery via median sternotomy. Patients are randomized into two groups: TTPB + SAPB Group: Patients receive ultrasound-guided blocks targeting the anterior and lateral chest wall. ESPB Group: Patients receive ultrasound-guided blocks targeting the paravertebral and intercostal spaces from a posterior approach. Intervention and Procedures: Following standardized anesthesia induction and invasive monitoring, the respective blocks are performed under ultrasound guidance. Intraoperative hemodynamic data are recorded at key surgical stages (incision, sternotomy, CPB). In the postoperative period in the intensive care unit (ICU), all patients will receive a standardized multimodal analgesia protocol including intravenous (IV) paracetamol and IV tenoxicam. While patients are intubated, pain will be assessed using the Behavioral Pain Scale (BPS). If the BPS score is above 3, IV fentanyl will be administered as rescue analgesia. Following extubation, pain levels will be evaluated using the Visual Analog Scale (VAS) at rest and during coughing at specific time points (0, 1, 2, 4, 8, 12, 16, and 24 hours). If the post-extubation VAS score is 4 or higher, intramuscular meperidine will be given as rescue analgesia. Additionally, IV ondansetron will be administered in case of nausea or vomiting. The study will also evaluate the time to extubation, time to clinical transport, and patient/surgeon satisfaction using a 5-point Likert scale. Primary and Secondary Outcomes: The primary objective of this study is to compare postoperative pain intensity between the study groups using the Visual Analog Scale (VAS) (0-10) and the Behavioral Pain Scale (BPS) (3-12). Secondary objectives include: Opioid Consumption: Comparison of total intraoperative and postoperative opioid (IV fentanyl and IM meperidine) consumption within the first 24 hours. Recovery Milestones: Measurement of time to extubation, time to first mobilization, and time to clinical transport to the surgical ward. Clinical Satisfaction and Safety: Assessment of patient and surgeon satisfaction using a 5-point Likert scale, and monitoring the incidence of opioid-related side effects, specifically postoperative nausea and vomiting (PONV) requiring ondansetron. Expected Impact: By identifying the most effective regional anesthesia technique (TTPB+SAPB vs. ESPB) in conjunction with a standardized multimodal analgesia protocol (IV paracetamol and tenoxicam), this study seeks to maximize postoperative pain control and patient comfort. The results aim to achieve superior analgesia with lower pain scores, thereby facilitating earlier mobilization, reducing the incidence of postoperative complications, and enhancing the overall recovery process for patients undergoing cardiac surgery via median sternotomy. This approach ultimately contributes to the development of more effective, pain-centered recovery protocols in the intensive care unit.

The purpose of this clinical study is to evaluate the effect of Whole Body Vibration (WBV) therapy, applied two weeks after botulinum toxin type A (BoNT-A) injection, on spasticity and balance parameters in individuals with stroke who have ankle spasticity. The main questions it aims to answer are: Adjuvant WBV therapy administered after BoNT-A injection; * Does it effectively improve spasticity? * Is it an effective intervention for balance and walking functions? Researchers will compare the application of WBV to a placebo application (a vibration-free application) to evaluate the effect of adjuvant WBV therapy administered after BoNT-A injection on ankle spasticity, balance, and walking function in individuals with stroke.

The study was planned to evaluate the effects of discharge training on PEG use given to palliative care patients' relatives on the caregiver burden and quality of life of the relatives. The main questions that the study aims to answer are as follows: * How does PEG training given before discharge affect the knowledge level of caregivers on PEG use? * How does PEG training given before discharge affect the caregiver burden? * How does PEG training given before discharge affect the caregiver's caregiver stress? * How does PEG training given before discharge affect the quality of life of the caregivers? The researchers will compare the PEG training given before discharge with a control group that did not receive training in this regard in order to evaluate the effects of PEG training given before discharge on the caregiver burden, caregiver stress and quality of life of the caregivers. The study will use a general information form, the Caregiver Burden Scale, the Caregiver Stress Index Form, the SF 36 Quality of Life Scale, and the Percutaneous Endoscopic Gastrostomy Tube Nutrition Information Scale for Caregivers. Participants: * Face-to-face interviews will be conducted with caregivers at 0, 1, and 3 months. * The forms used in the study will be filled out at each interview. * The intervention group will be trained only at the first interview.

In our study, we primarily aimed to compare the postoperative analgesic effectiveness of the Serratus Posterior Superior Intercostal Plane Block and the Serratus Anterior Plane Block, both routinely applied in patients undergoing Video-Assisted Thoracoscopic Surgery (VATS)

Patients in the AI-supported mobile application group will be able to log in with a username and password that will be defined specifically for them. Patients will be informed about how the application is used during their first interview. They will enter their personal and disease characteristics (age, gender, height, weight, HbA1C, HDL, LDL) into the application at the entrance. Other sections of the application will include exercise, nutrition, medication tracking, complication tracking and diabetic foot care sections. The person will be asked to enter relevant information in these fields according to their own life and condition (for example; how many times do you use insulin per day, what are your medication times, how do you spend your day in terms of exercise, how many meals do you eat, what is your diet, do you urinate frequently, are you extremely thirsty, are you hungry often, do you have numbness in your hands and feet, etc.). After the patient enters the necessary information, they will also be asked to enter their daily blood sugar measurement values into the system. Thus, the individual\'s hypo/hyperglycemia risk, risk analysis, nutrition recommendations, medication reminder system, exercise reminder and incentive warnings will be communicated to the individual thanks to the AI-based mobile application. The aim of this application is to reduce the risk of complications and improve the individual\'s quality of life by providing personalized recommendations for all the needs of the individual, including alarms and reminders, and to support patients to continue their diabetes education and disease management more actively.

This study will be conducted to investigate the effects of hot foot baths on patients' sleep quality and fatigue severity levels.The study will be conducted in the Gastroenterology clinic of a university hospital in Türkiye. The research sample will consist of 60 adult patients. Patients will be randomly divided into two groups: the intervention and control groups. The intervention group will receive hot foot baths for three consecutive nights starting from the second day of hospitalization. The foot bath will be applied one hour before the patient goes to bed at night. The foot tub will be filled with hot water to approximately 20 cm above the patient's ankle and the temperature of the water will be measured with a water thermometer. The temperature of the water will be kept stable at 41-42°C. This application will be done for 20 minutes. The sleep and fatigue levels of the patients will be measured with measurement tools in the morning (3 times) following each application. No application will be applied to the control group, and sleep and fatigue levels will be measured in a similar manner to the measurement tools applied to the intervention group and the application days.

The aim of this study is to evaluate the effectiveness of adding fentanyl to the TAP block in laparoscopic cholecystectomy cases. It is hypothesized that the addition of fentanyl to the TAP block will enhance the quality of postoperative analgesia and prolong the duration of blockade compared to the TAP block performed with bupivacaine alone. The study aims to determine the most effective approach by comparing these two treatment methods with a control group.

Spinal anesthesia is frequently administered using the conventional landmark technique. Ultrasound is a non-invasive and safe approach. Neuroaxial anesthesia procedures can be conducted using two different ultrasound techniques; Real-Time Ultrasound Guided (USRTG) and Ultrasound-Assisted (USAS). The primary objective of this study is to compare the successes of spinal anesthesia applications using USRTG, USAS, and conventional landmark techniques on the first attempt in obese patients undergoing orthopedic surgery.

The operating room environment can be frightening for pediatric patients. Many techniques have been used to make the operating room environment less intimidating, including allowing parents to accompany part of this procedure, play therapy and various distraction strategies during the entrance to the operating room. In a survey study, it was reported that parents were expected to create hospital conditions with a more child-friendly atmosphere. In this context, it is thought that creating a warmer environment for children, including the clothes worn in the operating room, may reduce the anxiety level of children. In this study, investigators' aim was to investigate the effect of wearing an hospital gown with cartoon characters on the reduction of preoperative anxiety in children scheduled for Orthopedic surgery by in the operating room.
