Clinical trials

This prospective observational cohort study aims to compare the safety and clinical outcomes of sedated and unsedated percutaneous endoscopic gastrostomy procedures in elderly patients classified as ASA IV. The primary outcome is the development of cardiopulmonary complications within the first 24 hours after the procedure. Secondary outcomes include technical success, procedure duration, early procedure-related complications, length of hospital stay, intensive care requirement, 30-day mortality, and 30-day readmission.

Pain, defined by the International Association for the Study of Pain as a subjective, sensory, and emotional experience, differs from nociception, which is merely a neural activity. Premature newborns, whose inhibitory fibers are not yet mature due to anatomical and physiological development and who have insufficient endogenous opioid release, experience painful stimuli much more intensely. The inability of this age group to verbally express pain makes the diagnosis, assessment, and management of pain entirely dependent on healthcare professionals. Pain that is not effectively managed leads to stress and loss of comfort in the short term, while in the long term it can cause permanent neurodevelopmental problems and alter the individual's pain threshold later in life. Premature infants, especially those in Neonatal Intensive Care Units (NICUs), are exposed to invasive procedures that cause moderate to severe pain, such as heel prick tests, much more frequently than healthy term infants. In this context, pain management is a fundamental and essential nursing responsibility for the infant's neuroprotective developmental care. The literature shows that various non-pharmacological methods, such as oral sucrose, non-nutritive sucking (NNS), facilitated flexion, and wrapping, are used to alleviate pain during interventional procedures. Although more readily available in NICUs, studies on the effectiveness of oral glucose solutions are more limited compared to sucrose. This research, designed to address this gap in the existing literature, aims to investigate the effect of "oral breast milk, 20%, and 10% dextrose solution administered with supportive positioning methods" on pain reduction during heel prick blood sampling in premature newborns. The results of this research are expected to contribute to the development of a new, easily applicable, effective, and evidence-based nursing intervention strategy for NICUs.

The aim of this study is to investigate the postoperative pain relieving effect of preoperative genicular block in total knee arthroplasty surgery. The main questions it aims to answer are: 1. Do visual analog scale (VAS) scores decrease in patients who underwent geniculate block? 2. Does opioid consumption decrease in patients who underwent geniculate block? Researchers will compare postoperative pain in patients who received genicular block with those who did not.One group of patients will be administered 0.25% bupivacaine with the geniculate block method. The other group will not undergo any intervention. Both groups will be administered intravenous morphine for postoperative analgesia.

Pilonidal sinus disease is a common condition. There is still ongoing research on the ideal treatment. Pilonidal sinus disease is most common in men between the ages of 20 and 30. For patients with symptoms of pilonidal sinüs (pain, itching and discharge with soiling of underwear) that interfere with their normal daily life, several treatment options have emerged. A hairy body, thick skin, overweight, a deep gluteal cleft, lack of hygiene, sedentarism, repeated chafing and previous familial history are commonly admitted as predisposing factors. There are various surgical and non-surgical methods for its treatment. Many different surgical techniques have been defined. None of these surgical techniques are defined as 'gold standard'. For many years, wide excision and secondary healing was the standard approach for pilonidal sinus disease. However, when this method resulted in prolonged healing and restriction of regular activities, various reconstructive methods were developed to demonstrate the disadvantages of secondary healing. A minimally invasive treatment modality for pilonidal sinüs dissease is excision of the sinus pit(s) followed by application of phenol to the sinus tract. Phenol is a sclerosing agent that destroys the epithelium and debris in the sinus, and is, thus, able to promote healing of the sinus. Recently, advances in laser technology have made laser ablation of the sinus tract possible. The aim is to destroy and obliterate the sinus tracts with thermal energy produced by the laser probe. The aim of this prospective observational study was to compare phenolization and laser ablation in the treatment of pilonidal sinus disease.

Fear and anxiety experienced by children during inhalation therapy (using a nebulizer or vaporizer) are key factors that make treatment compliance difficult and reduce the quality of care. Young children, in particular, may perceive this process as "threatening" due to mask use, the noise produced by the device, and a sense of loss of control. This situation triggers a significant physiological stress response in the child. Therefore, in pediatric nursing, non-pharmacological methods that increase children's participation in treatment are of great importance. The literature indicates that interventions such as showing cartoons, playing music, and using distracting visual materials both reduce anxiety and improve stress indicators like heart rate. Additionally, therapeutic play has been proven to help children adapt to the hospital environment and soothe their emotional reactions. This study aims to evaluate the effectiveness of a nursing intervention-designed to enhance children's physical comfort and manage their fear and anxiety during inhalation therapy-that is breath-synchronized, interactive, and story-based.

This study was designed to compare the effects of a prenatal education program based on the Indivisible Self Model with those of a needs-based prenatal education program on psychosocial outcomes among pregnant women.

This randomized controlled trial aims to compare the effects of a web-based compassion-focused writing program and a reflective writing program on psychological well-being, self-compassion, postpartum trauma-related stress symptoms, and post-traumatic growth in midwives working in delivery rooms.

We planned a study to determine the effect of showing an animated video and using educational therapeutic play methods prior to throat swab procedures in children aged 4-8 years on the children's compliance with the procedure, as well as on their emotional expression, fear and anxiety levels, and to compare the superiority/effectiveness of these two methods against one another. The sample size for the study was determined using an a priori power analysis conducted with the G\*Power (v3.1.9.7) programme. It is planned to include a total of 105 children, with at least 35 children in each group. The study will be conducted using a single-blind, parallel-group, three-group experimental design. By demonstrating the effects of two different modern approaches on children's compliance, fear, anxiety and emotional responses during the throat swab procedure, this study will contribute to the development of evidence-based, atraumatic care practices in paediatric clinics.

This study was designed to compare the effects of web-based gamification and online classical teaching methods on knowledge level, motivation toward instructional materials, clinical self-efficacy, and satisfaction in midwifery students receiving postpartum hemorrhage management education.

This single-center, parallel-group, randomized experimental study will compare the effects of two active non-pharmacological interventions - distraction-card use and emotion-regulation toy squeezing - on procedural pain and pain-related fear during intramuscular tetanus vaccination in children aged 4-7 years. Eligible children will be randomized to either the distraction-card group or the emotion-regulation toy-squeezing group. Pain will be assessed using the Wong-Baker FACES Pain Rating Scale, and pain-related fear will be assessed using the Children's Fear Scale before, during, and after the intramuscular injection procedure. Hypotheses * H1a: There is a difference between the groups in mean Wong-Baker FACES scores during the procedure. * H1b: There is a difference between the groups in mean Children's Fear Scale scores during the procedure.

The study aimed to determine the effects of a mobile application and an artificial intelligence-supported educational video, developed for patients who will perform clean intermittent catheterization (CIC), on patients' adherence, levels of difficulty, self-confidence, infection parameters (urinalysis, urine culture, infection incidence), and recurrent hospital admissions.The number of CIC patients who applied to the Urology Outpatient Clinic of Mersin University within the last year was 110. Since no similar study was found, the sample size was calculated using an a priori power analysis with G\*Power 3.1.9.7 software. . As a result of the power analysis, the total sample size was calculated as 90, with 30 participants in each group. Considering a possible data loss (dropout) rate of approximately 10%, it was planned to include 33 participants in each group (a total of 99 participants) at the beginning of the study.Data will be collected using the "Descriptive Information Form," "Intermittent Catheterization Adherence Scale," "Self-Confidence Scale in Clean Intermittent Self-Catheterization," "Intermittent Catheterization Difficulty Questionnaire," and the "Patient Follow-up Form."Patients who will perform clean intermittent catheterization will receive training through a mobile application (intervention group 1) and an artificial intelligence-supported educational video (intervention group 2). Patients in the control group will be trained using the routine brochure provided in the outpatient clinic.

This study was designed as a randomized controlled trial to determine the effect of a stress ball applied before retrograde intrarenal surgery on patients' anxiety levels, surgical fear, and hemodynamic parameters.

The Effect of Using a Stress Ball During Transrectal Ultrasound-Guided Prostate Biopsy on Anxiety, Pain, and Hemodynamic Variables

Transforaminal epidural steroid injection (TFESI) is a minimally invasive procedure commonly used for the management of lumbar radicular pain. It is intended to reduce inflammation around the affected nerve root, limit edema, and modulate nociceptive transmission, with the aim of relieving pain, improving physical function, and potentially reducing the need for surgery. Although TFESI may improve function and quality of life, treatment benefit is not uniform, and the degree of pain relief and patient satisfaction may differ across individuals. This prospective observational study aims to evaluate postprocedural pain intensity and patient satisfaction in individuals undergoing lumbar TFESI and to identify clinical and demographic factors associated with satisfaction. Demographic and clinical characteristics, medical and surgical history, procedural pain scores, anxiety level, postprocedural pain scores, sedation status, fluoroscopy-related metrics, and intraprocedural events will be recorded. Patient satisfaction will be assessed 1 hour after the procedure using a Likert-based questionnaire, and operator satisfaction will also be documented. By examining patient-reported outcomes together with procedural and clinical variables, this study seeks to provide a more standardized assessment of real-world TFESI outcomes and to support better patient selection and follow-up strategies.

Music therapy is a non-invasive method with no side effects and can be administered independently by a nurse. Nevertheless, it should be noted that music therapy can be discontinued if any adverse effects are experienced by patients during the research process. After completing the music listening session, eye masks and earplugs, which are effective in reducing sleep problems in patients, will be applied from 11:00 p.m. to 7:00 a.m. All patients will be asked to complete the DAÖ at 10:00 PM and 10:30 PM. The RCUÖ will be requested to be completed by all patients between 8:00 AM and 9:00 AM the following morning.

This randomized controlled trial aims to evaluate the effect of a mindfulness-based nursing intervention on anxiety levels and vital signs in patients undergoing open-heart surgery during the preoperative and early postoperative periods.

This prospective observational study aims to evaluate the clinical outcomes of patients with single-level lumbar disc herniation who undergo routine percutaneous laser disc decompression (PLDD). In routine clinical practice, some patients receive an additional transforaminal anterior epidural steroid injection during the same session without an extra puncture. This study will prospectively follow patients who receive PLDD alone and those who receive PLDD combined with epidural steroid injection. Pain intensity, functional status, analgesic use, need for additional interventions, and complications will be assessed over time. The results may help to clarify whether adding epidural steroid injection to PLDD improves clinical outcomes in patients with lumbar disc herniation.

This observational study aims to evaluate changes in the spinal cord following CT-guided percutaneous cervical cordotomy performed for the treatment of intractable cancer-related pain. Cordotomy is a routine clinical procedure used to relieve severe pain in selected cancer patients. After the procedure, some patients may develop temporary neurological symptoms that are thought to be related to spinal cord edema. In this study, magnetic resonance imaging (MRI) will be performed as part of routine clinical follow-up on postoperative day 1 and at 1 month to assess the presence and extent of spinal cord edema. Clinical outcomes, including pain intensity and possible postprocedural symptoms, will be recorded and compared with MRI findings. The goal of this research is to better understand the relationship between imaging changes in the spinal cord and clinical outcomes after cordotomy, which may help improve patient care and postoperative management in the future.

In dentistry, particularly in posterior teeth with extensive caries or old restorations, the extension of restoration margins below the gingival level presents a significant clinical challenge. In such cases, restorative procedures become more complicated, periodontal health may be adversely affected, and long-term tissue loss can occur. To overcome this problem, the "Deep Margin Elevation" technique has been developed. This approach aims to raise subgingival margins caused by caries or fractures above the gingival level, thereby providing a healthier and more favorable foundation for successful treatment. In this study, two different materials will be used for deep margin elevation, followed by restoration of the teeth with indirect restorations fabricated using additive manufacturing technology, which has become increasingly popular in recent years. Two different additive manufacturing resins will also be applied in the restorative phase. The teeth treated with deep margin elevation and indirect restorations will be evaluated at baseline, 6 months, and 12 months according to the FDI criteria, as well as periodontal parameters due to the involvement of the gingival region. This study aims to highlight the importance of material selection in restorative treatment planning and to scientifically demonstrate the impact of the applied technique on surrounding tissues. Furthermore, it will provide an evidence-based perspective on how adopting a tissue-friendly approach during restorative procedures may contribute to favorable long-term outcomes.

Additive manufacturing, also referred to as "3D printing" or "rapid prototyping," is defined as the process of joining materials layer by layer to create an object based on 3D model data. In this method, a digital data set is first created on a computer (computer-aided design, CAD) and then transferred to a 3D printer. The designed object is produced by printing it in successive layers. In contrast, in subtractive manufacturing, restorations are produced by milling homogeneous blocks based on computer-designed models. Compared to subtractive manufacturing technology, additive manufacturing allows for the production of more complex, detailed, and larger structures with much less material waste and without excessive use of force. It is thought that additive manufacturing has the potential to overcome the disadvantages of subtractive manufacturing. Over the past decade, global sales of industrial and personal 3D printers, materials, and services have increased by more than 33% annually. Due to its success in the production of surgical guides, temporary and permanent restorations, crowns and bridges, occlusal splints, frameworks, and orthodontic appliances, this technology has attracted significant interest in the field of dentistry. Although additive manufacturing has started to be used as an alternative to subtractive manufacturing in many applications, there is still a lack of information regarding the chemical composition, mechanical, and physical properties of printable resins. Moreover, clinical data on the use of these resins in permanent restorations are quite limited. Therefore, the aim of this study is to clinically evaluate and monitor for one year the performance of onlay restorations fabricated with three different resins of varying compositions in endodontically treated teeth.

Surgical smoke refers to the gaseous plume released into the air as a result of the thermal destruction of tissues by energy-based devices used in operating rooms. The composition of surgical smoke may include various organic compounds. In the literature, the most frequently identified chemical substances in surgical smoke are formaldehyde, acrolein, hydrocarbons, fatty acids, hydrocyanic acid, phenols, nitriles, acrylonitrile, hydrogen cyanide, benzene, and toluene. These particles can negatively affect the health of the operating room personnel. According to current guidelines, masks are recommended as the primary personal protective equipment to prevent respiratory exposure associated with surgical smoke. During surgical procedures, operating room staff frequently use surgical masks. Although surgical masks are the most commonly preferred personal protective equipment to protect healthcare workers against microorganisms and aerosols, they are unfortunately ineffective in filtering small particles. Therefore, the present study aimed to determine the impact of different types of masks on exposure to surgical smoke.
