Clinical trials

This randomized controlled trial aims to evaluate the effect of white noise on sleep, recovery quality, and satisfaction in patients undergoing laparoscopic cholecystectomy. In the postoperative period, patients encounter numerous physical and psychological stressors, such as pain, difficulty adapting to the hospital environment, immobilization, environmental noise, frequent nursing interventions, individual characteristics, and illness-related anxieties. These factors disrupt sleep patterns; a decline in sleep quality can negatively affect tissue healing, immune function, pain control, psychological well-being, and the overall recovery process. Consequently, patient satisfaction with the care process may also decrease. Although pharmacological methods are commonly used to manage postoperative insomnia, they are not always sufficiently effective and carry various limitations, such as sedation, drug interactions, and other adverse effects. Therefore, interest has grown in recent years regarding non-pharmacological interventions that are safe, cost-effective, easy to implement, and carry a low risk of side effects. White noise, one such intervention, can create a more favorable sleep environment by masking irregular environmental sounds, promote relaxation, and has the potential to improve sleep quality.

This randomized controlled trial aims to investigate the effects of preoperative video-assisted patient education combined with eye position fixation training on anxiety, pain, intraoperative compliance, operation duration, and physiological parameters in adult patients undergoing primary pterygium surgery under local anesthesia. A total of 152 patients aged 18 to 75 years scheduled for primary pterygium excision with conjunctival autograft will be randomly assigned to either the intervention group (n = 76) or the control group (n = 76). Patients in the intervention group will receive an 8-to-10-minute tablet-based audiovisual surgical preparation module prior to surgery. This module consists of two stages: (1) cognitive preparation based on Enhanced Recovery After Surgery (ERAS) principles, including 2D animations of the procedure, desensitization to operating room sights and sounds, and postoperative care instructions; and (2) interactive eye position fixation and motor compliance training. Patients in the control group will receive standard routine verbal preoperative information. Anxiety levels, pain intensity, and physiological parameters (blood pressure, heart rate, respiratory rate, and oxygen saturation) will be assessed preoperatively and postoperatively. Intraoperative patient compliance and surgical comfort will be evaluated immediately after surgery by a blinded surgeon, along with total operation duration and intraoperative physiological parameters.

This study aims to investigate the effects of preoperative white noise and pink noise interventions on sleep quality, anxiety, postoperative pain, nausea, and physiological parameters in patients undergoing elective total hip arthroplasty (THA) or total knee arthroplasty (TKA). A total of 165 adult patients will be randomly allocated into three equal groups: a white noise group, a pink noise group, and a control group (55 participants per group). On the evening prior to surgery (around 10:00 PM), participants in the experimental groups will listen to standardized white noise or pink noise at 45-50 dB for 30 minutes via over-ear, active noise-cancelling headphones. Participants in the control group will receive routine perioperative care without any auditory intervention. Data regarding sleep quality, anxiety levels, pain intensity, nausea, and hemodynamics (blood pressure, heart rate, respiratory rate, and oxygen saturation) will be collected using validated scales and physiological monitoring before and after the intervention as well as in the postoperative period (at 0, 12, and 24 hours).

The purpose of this study is to evaluate the acute psychological and physiological effects of a single-session structured horticultural therapy program on patients undergoing routine hemodialysis. The study is designed as a two-arm, parallel, pretest-posttest randomized controlled trial conducted at Bingöl State Hospital. Participants are randomized (1:1) to either an experimental group receiving a 45-60 minute individual horticultural therapy session (e.g., planting and caring for Tagetes erecta, Celosia cristata, and Petunia grandiflora) or a control group maintaining standard waiting conditions for the same duration during non-dialysis days. Primary outcomes evaluate acute changes in state anxiety (measured via STAI-1) and physiological stress response (measured via salivary cortisol concentration) before and immediately after the intervention.

This study is a two-arm controlled interventional study designed to evaluate the effect of a Kolcaba's Comfort Theory-based educational intervention on the quality of life of patients with epilepsy. Eligible participants will be assigned to either an intervention group or a control group. Participants in the intervention group will receive a structured educational program developed according to the principles of Kolcaba's Comfort Theory in addition to routine care, whereas participants in the control group will receive routine care only. Quality of life assessments will be conducted at baseline and after the intervention period using validated measurement instruments. The primary objective is to determine whether the theory-based educational intervention improves the quality of life of patients with epilepsy compared with routine care.

Hemodynamic change after induction of general anesthesia is usually judged from mean arterial pressure. Pressure, however, is a surrogate for flow, and the two can separate: cardiac output may fall while arterial pressure remains apparently adequate. The interval that follows induction of anesthesia, before surgical stimulation begins and while hemodynamic conditions are determined by anesthetic management alone, has not been characterized in terms of flow. This study is designed to define post-induction low cardiac output (PiLCOs) in patients undergoing coronary artery bypass grafting. This is a prospective, observational, two-centre cohort study. Consecutive adults undergoing isolated coronary artery bypass grafting with cardiopulmonary bypass at two tertiary cardiovascular surgery centre will be enrolled. No aspect of anesthetic or surgical management will be altered for the purposes of the study. An arterial catheter is sited before induction while the patient is awake, and cardiac index is recorded continuously at 30-second intervals by arterial waveform analysis. Mean arterial pressure, heart rate, stroke volume index and cardiac index are recorded at the same resolution. The analysis window is the 30 minutes that follow induction of anesthesia. The period of cardiopulmonary bypass is excluded from all analyses, because flow during bypass is generated by the pump rather than by the heart. The primary outcome has two components, both defined over that window and both referenced to a cardiac index threshold of 2.0 L/min/m2. The first is the total time spent below threshold, in minutes. The second is the cumulative low-output burden, defined as the integral over time of the difference between the threshold and the measured cardiac index, taken only where that difference is positive. Dimensional analysis reduces the unit of burden to L/m2, a body-surface-indexed volume of undelivered flow, which multiplied by body surface area yields an absolute flow deficit in liters. Time below threshold describes how long the exposure lasts and cumulative burden describes how deep it is. The two together define the exposure, and neither alone is sufficient. Secondary outcomes are the same two measures computed at cardiac index thresholds of 2.2 and 2.5 L/min/m2; the incidence of PiLCOs, defined as at least one measurement below 2.0 L/min/m2 within the window; the time-weighted average depth across the window and the median depth sustained while below threshold; the distribution of cumulative burden across the three consecutive ten-minute segments of the window; and the time from induction to the first measurement below threshold. Exploratory analyses will examine the association between the presence and the magnitude of PiLCOs and the postoperative course, including acute kidney injury, serum lactate, duration of mechanical ventilation, intensive care unit and hospital length of stay, and mortality. All outcome analyses are treated as exploratory and hypothesis-generating, and no adjustment is made for multiple comparisons. Sample size was derived from an internal pilot of 30 patients, comprising the first 15 consecutive patients enrolled at each centre. In that pilot the standard deviation of time below threshold was 8.14 min and the incidence of PiLCOs was 70.0%. Setting the half-width of the 95% confidence interval at 1.7 min for mean time below threshold requires 88 patients, and setting it at 9.5 percentage points for incidence requires 90; the larger figure was carried forward and rounded to 90, allocated as 45 patients per centre. Allowing 15% for withdrawal, protocol deviation and unusable recordings gives a planned enrollment of 104 patients. Because the study estimates the frequency and the magnitude of an event that has not previously been characterized, rather than testing a prespecified superiority hypothesis, sample size is based on the precision of estimation rather than on power.

This randomized clinical trial compares the antibacterial effects of calcium hydroxide and a calcium silicate-based intracanal medicament in teeth with acute apical abscesses. Microbiological samples are collected before root canal preparation, after chemomechanical preparation, and after intracanal medication. Bacterial levels are measured using Real-Time PCR. The main objective is to determine which intracanal medicament provides a greater reduction in the total bacterial load after a 7- to 10-day medication period.

This study aims to evaluate the effect of a Health Belief Model (HBM)-based disaster education program on general disaster preparedness beliefs and disaster preparedness levels among parents of children with special needs. Children with special healthcare and developmental needs are particularly vulnerable during disasters, and parental readiness plays a critical role in mitigating risks. The study is designed as a quasi-experimental (or randomized controlled) interventional trial with an intervention and a control group to determine whether structured, model-based training improves preparedness behaviors and disaster beliefs among parents.

This study aims to evaluate the diagnostic performance of the cardiovascular surgeon's visual estimation of LV function before decannulation following cardiopulmonary bypass, using TEE results as the reference standard.

After obtaining informed consent, pre-test applications will be performed on participants in the experimental and control groups following randomization, and information regarding treatment plans will be recorded. Patients in the experimental group will receive laughter yoga practice integrated with virtual reality videos during chemotherapy infusion. The practice is planned to be once a week for four weeks. High-resolution, adjustable virtual reality glasses with head and hand tracking features will be used for the virtual reality application. The videos will consist of relaxing content such as nature walks, beach and sea views, and will be prepared in three-dimensional, 360-degree viewing angles integrated with laughter yoga exercises. Personalized video content will be created according to the participants' preferences, and the viewing time will be limited to 10 minutes for each application. After the completion of the fourth course, data collection tools will be re-administered for post-testing purposes.

This randomized controlled trial aims to evaluate whether a mandala coloring activity during labor can reduce birth anxiety and fear of childbirth among primiparous pregnant women experiencing their first birth. The study will be conducted among eligible primiparous women admitted to the delivery unit at Şanlıurfa Training and Research Hospital during active labor. A total of 140 primiparous pregnant women will be randomly assigned to either an intervention group or a control group. Women in the intervention group will receive standard labor care in addition to a structured mandala coloring activity beginning when cervical dilation is between 5 and 8 cm. Participants will be provided with standardized mandala drawings and coloring pencils and will be encouraged to color during contractions as tolerated until birth. Women in the control group will receive routine labor and obstetric care without an additional art-based or distraction intervention. Routine maternal and fetal monitoring will continue in both groups throughout labor. Birth-related anxiety and fear will be assessed before the intervention during the active phase of labor and after birth. The study will use validated measures to evaluate fear of childbirth and birth-related anxiety. The study will also record relevant obstetric outcomes, including mode of delivery, analgesia use, and duration of labor. The study seeks to answer whether adding a simple, low-cost, non-pharmacological mandala coloring activity to routine labor care can reduce birth anxiety and fear of childbirth in primiparous women. The findings may provide evidence for the use of accessible, non-pharmacological supportive interventions as part of midwifery care during labor.

This study is a quasi-experimental research project with a pretest-posttest control group design, structured to determine the effect of organized gardening activities on peer interaction, stress levels, and nature engagement behaviors among university students.The population of the research consists of students from the Vocational School of Health Services (VSHS) at Bingol University. The sample size, determined via G\*Power analysis (including a 20% anticipated drop-out rate), comprises a total of 100 volunteer students, divided into an intervention group (n = 50) and a control group (n = 50).The intervention group will participate in a structured program held twice weekly for 1 month (totaling 8 sessions, 60-90 minutes each) in the VSHS garden, encompassing soil preparation, paired seedling planting, group-oriented maintenance, and landscaping activities. The control group will maintain their routine campus life.Data will be collected using a Personal Information Form, the Perceived Self-Efficacy Scale (Coping with Stress), the University Life Scale (Peer Relations Subscale), and the Connectedness to Nature Scale. The data will be evaluated through homogeneity tests and parametric/non-parametric comparative analyses (t-tests, Wilcoxon, Mann-Whitney U).Contingency plans (Plan B)-such as indoor potted plant/terrarium workshops and buffer sample recruitment-are established to address adverse weather conditions, sample attrition, and seasonal risks.

This study is a randomized, controlled trial with a pre-test/post-test design, conducted to determine the effects of Generative AI (GenAI)-supported learning on academic achievement, learning efficiency, and critical thinking within a university setting. The study population consists of students from the Dialysis Program at Bingöl University's Vocational School of Health Services; the sample comprises 100 volunteer students who met the inclusion criteria and were randomly assigned to either an experimental group (n=50) or a control group (n=50). The experimental group will participate in a "Generative AI-Supported Learning Program" over the course of one month-meeting two days a week for a total of eight 60-minute sessions-covering topics ranging from effective prompting techniques to case analysis and academic ethics; meanwhile, the control group will continue with their routine educational activities. Data will be collected using a Demographic Information Form, the Academic Achievement Inventory, the Critical Thinking Disposition Scale, and the Artificial Intelligence Dependency Scale, and will be analyzed using biostatistical methods (t-tests, ANCOVA, and effect size calculations).

This single-center, split-mouth, randomized controlled clinical trial aims to evaluate the clinical effectiveness of Minimally Invasive Non-Surgical Therapy (MINST) as an adjunct to conventional non-surgical periodontal therapy in patients with Stage III/IV periodontitis. Twenty-three systemically healthy adults presenting with bilateral molar teeth exhibiting periodontal pockets ≥5 mm with bleeding on probing will be enrolled. In each participant, molar teeth will be randomly allocated to receive either conventional subgingival scaling and root planing (SRP) using ultrasonic instruments alone (control) or conventional SRP followed by MINST using Mini-Five Gracey curettes under magnification loupes (test). Clinical periodontal parameters, including Plaque Index (PI), Gingival Index (GI), Bleeding on Probing (BOP), Probing Pocket Depth (PPD), and Clinical Attachment Level (CAL), will be evaluated at baseline, 3 months, and 6 months after treatment. The study will investigate whether MINST provides superior clinical outcomes compared with conventional non-surgical periodontal therapy.

Menopause is a natural stage in a woman's life characterized by the permanent cessation of ovarian function and is frequently accompanied by vasomotor, psychological, urogenital, and sleep-related symptoms that can substantially impair quality of life. Although pharmacological treatments are available, many women seek non-pharmacological interventions to manage menopausal symptoms and improve their overall well-being. Mindfulness- and compassion-based interventions have shown promising effects on psychological health, stress reduction, and quality of life in different populations; however, evidence regarding the effectiveness of Mindfulness-Based Compassionate Living (MBCL) for women experiencing menopause remains limited. This randomized controlled trial aims to evaluate the effectiveness of a Compassionate Living Education Program based on the principles of Mindfulness-Based Compassionate Living in improving symptom management and quality of life among menopausal women. The study will be conducted with menopausal women recruited from primary healthcare settings in Kars, Türkiye. Participants who meet the eligibility criteria will be randomly assigned to either an intervention group or a control group. Participants in the intervention group will receive an eight-session online Compassionate Living Education Program delivered by a certified instructor. The program includes mindfulness practices, self-compassion exercises, breathing and relaxation techniques, compassionate imagery, loving-kindness meditation, and home practice assignments designed to strengthen emotional regulation, self-kindness, and adaptive coping skills. The control group will receive routine care only. Primary outcomes will include menopausal symptom severity and menopause-specific quality of life. Secondary outcomes will include self-compassion, mindfulness, anxiety, depression, and stress. Data will be collected using validated self-report questionnaires before and after the intervention and analyzed using appropriate statistical methods. The findings of this study are expected to provide evidence regarding the effectiveness of Compassionate Living Education as an accessible, low-cost, non-pharmacological intervention for improving symptom management and enhancing the quality of life of menopausal women. The results may contribute to the development of evidence-based nursing and women's health interventions in primary healthcare settings.

Intravenous (IV) administration, one of the most fundamental and common practices carried out by nurses, is defined as the administration of medication directly into the circulatory system via a vein. Intravenous administration is one of the key clinical skills that must be performed using the correct technique. Supporting students' motivation to learn plays a significant role in the effective acquisition of this skill. The ARCS-V motivation model, which aims to enhance motivation during the teaching process, comprises the dimensions of attention, relevance, confidence, satisfaction and action. This study aims to investigate the effect of intravenous administration training based on the ARCS-V model on nursing students' levels of motivation and academic self-efficacy. The study will be conducted using a mixed-methods design incorporating both a randomised controlled trial and qualitative research methods. In the study, the experimental group will receive IV administration training structured according to the ARCS-V model, whilst the control group will be taught using the traditional teaching method. For the collection of quantitative data in this study, the "Demographic Information Form", the "Motivation Scale for Teaching Materials (ÖMMÖ)", the "Academic Self-Efficacy Scale (AÖÖ)" and the "Volition to Learn Scale (VFLS)" will be used. For the collection of qualitative data in the study, a "Semi-Structured Interview Form" will be used to determine the experiences of students in the experimental group regarding the learning process, and an audio recorder will be used to record the data. Whilst the quantitative data obtained will be analysed using statistical methods, the qualitative data will be evaluated through content analysis. It is anticipated that the findings of this research will demonstrate that teaching based on the ARCS-V model contributes to clinical skills training by supporting students' active participation in the learning process, as well as their motivation and will to learn.

This study was conducted to investigate the effects of progressive relaxation exercises, performed with the assistance of a therapeutic clown during the pre-operative period, on fear, anxiety and physiological parameters in children. This randomised controlled trial included children aged 6-10 years undergoing circumcision surgery. The children were randomised into three groups: a progressive relaxation exercise group led by a therapeutic clown, a progressive relaxation group led by a nurse, and a control group. Fear, anxiety and physiological parameters (heart rate, respiratory rate, blood pressure, oxygen saturation) were assessed before and after the procedure.

Cataract is an ocular disorder resulting from lens opacity; it stands as the most common cause of preventable blindness worldwide and significantly impairs the quality of life in elderly individuals. Surgical treatment utilizing small-incision phacoemulsification is the most effective solution for cataracts. Cataract surgery is generally performed under local anesthesia, which requires patients to remain awake throughout the operation, thereby potentially increasing their anxiety experiences. Elevated anxiety not only reduces patient comfort but can also lead to alterations in physiological parameters and a prolongation of the operation time. Furthermore, it is observed that the surgical drapes used to maintain the sterility of the surgical field during the operation cause discomfort to the patient. The weight and positioning of these drapes can cover the patient's mouth and nose area during the ongoing surgery, creating a sensation of difficulty in breathing (dyspnea). In addition to these circumstances, standard oxygen support is provided to the patient during cataract surgery performed under local anesthesia. This support is administered nasally via an open-ended oxygen tubing from beneath the surgical drape, aiming to ease the patient's respiration. However, when the oxygen flow rate is increased based on the patient's needs, high-velocity and high-concentration oxygen administration is observed to cause mucosal dryness, which shortly triggers reflex-induced irritative coughing attacks. For these reasons, it is crucial to keep anxiety under control, provide oxygen to prevent hypoxia, and monitor physiological parameters during cataract surgery.

This randomized controlled trial aims to evaluate the effect of Acceptance and Commitment Therapy (ACT)-based nursing interventions on social cognition, emotion regulation, and psychological flexibility in individuals diagnosed with schizophrenia. The study will be conducted at Erzincan Community Mental Health Center (TRSM) between October 2026 and January 2027. A total of 64 participants (32 experimental, 32 control) will be recruited from schizophrenia patients registered at the center. The experimental group will receive 8 structured group sessions based on ACT principles integrated into nursing practice (45-60 minutes per session, once weekly), while the control group will receive routine care only. Pre-test and post-test measurements will be obtained using the Observable Social Cognition Rating Scale (OSCARS), the Difficulties in Emotion Regulation Scale-Brief Form (DERS-16), and the Acceptance and Action Questionnaire-II (AAQ-II).

This study will examine whether Emotional Freedom Techniques (EFT) can reduce pain intensity, pain catastrophizing, and functional-emotional impact in nursing students with primary dysmenorrhea. Eligible participants will be randomly assigned to an intervention group or a control group. The intervention group will receive EFT-based support, and the control group will continue their usual coping practices. Study outcomes will be measured before the intervention, after the intervention, and at follow-up. This study may provide evidence for a safe, non-pharmacological approach to support students with primary dysmenorrhea.

The purpose of this clinical trial is to evaluate the effect of an artificial intelligence-supported digital education program developed based on the Neuman Systems Model on radiodermatitis severity and quality of life in women with breast cancer receiving radiotherapy. The intervention was developed based on the Neuman Systems Model, which served as the theoretical framework of the study. Educational content was structured according to the principles of the model and was designed to strengthen patients' flexible lines of defense, support resistance resources, facilitate adaptation to radiotherapy-related stressors, and promote system stability through primary, secondary, and tertiary prevention strategies. The study aims to answer the following questions: * Is a Neuman Systems Model-based AI-supported digital education program effective in reducing the severity of radiotherapy-induced radiodermatitis? * Is a Neuman Systems Model-based AI-supported digital education program effective in improving quality of life among women receiving radiotherapy for breast cancer? Participants assigned to the intervention group will be provided with access to the AI-supported digital education program developed in accordance with the Neuman Systems Model, whereas participants assigned to the control group will receive standard care. Differences between the groups with respect to radiodermatitis severity and quality of life outcomes will be evaluated. Participants will complete a Patient Information Form to collect sociodemographic and clinical characteristics prior to the initiation of radiotherapy. Radiodermatitis severity will be assessed using the Radiation Therapy Oncology Group (RTOG) Acute Radiation Dermatitis Scale, and quality of life will be evaluated using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and the breast cancer-specific module (EORTC QLQ-BR23). Following these assessments, participants will be randomly allocated to either the intervention group or the control group. Radiodermatitis severity will be evaluated weekly throughout the radiotherapy period using the RTOG scale and reassessed two weeks after completion of radiotherapy. Quality of life will be evaluated before radiotherapy and reassessed two weeks after completion of radiotherapy using the EORTC QLQ-C30 and EORTC QLQ-BR23 questionnaires. Participants assigned to the intervention group will be provided with access to an AI-supported digital education platform incorporating educational modules, personalized educational recommendations, reminder notifications, and motivational messages. In addition, system usability will be evaluated at the end of the intervention period using the System Usability Scale (SUS).

This prospective observational cohort study aims to evaluate the association between postpartum recovery quality and mother-infant bonding in women undergoing vaginal delivery. Postpartum recovery quality will be assessed using the Obstetric Quality of Recovery-10 (ObsQoR-10) questionnaire, and mother-infant bonding will be evaluated using the Postpartum Bonding Questionnaire (PBQ). Participants will be grouped according to routine clinical labor analgesia preference: women receiving labor epidural analgesia and women not receiving epidural analgesia. Additional assessments will include postpartum pain intensity, anxiety, depressive symptoms, and birth satisfaction. Baseline psychological assessments will be performed before delivery. The primary postpartum evaluation will be conducted between 6 and 24 hours after delivery. Exploratory follow-up assessments will be performed by telephone during postpartum week 2. The study aims to better understand the relationship between labor analgesia, postpartum recovery, and early mother-infant bonding outcomes after vaginal delivery.

This study aims to evaluate the effects of mindfulness-based self-management education on diabetes-related difficulties and empowerment in individuals with type 2 diabetes. Participants will receive a structured education program designed to improve self-care behaviors, emotional well-being, and confidence in managing their condition. The program includes mindfulness practices, diabetes self-management education, and supportive group sessions. Outcomes such as diabetes distress, self-management behaviors, and patient empowerment will be measured before and after the intervention. The findings of this study are expected to contribute to improving patient-centered care and supporting individuals with type 2 diabetes in managing their health more effectively.

This single-center randomized controlled clinical trial will evaluate the effects of structured early postpartum mother-infant skin-to-skin contact, with or without maternal lavender aromatherapy, after elective cesarean section on maternal stress biomarkers and early breastfeeding outcomes. The study will enroll 150 term pregnant women scheduled for elective cesarean section under spinal anesthesia at Ataturk University Research Hospital. Participants will be randomized into three groups: routine postoperative care, structured skin-to-skin contact, and structured skin-to-skin contact combined with inhalational lavender aromatherapy. The primary outcome is the change in maternal salivary cortisol level from immediately after birth to 60 minutes postpartum. Secondary outcomes include maternal salivary IgA levels, state anxiety scores, postoperative pain and nausea, time to first analgesic requirement, early breastfeeding initiation and success, LATCH scores, neonatal axillary temperature, cumulative duration and continuity of skin-to-skin contact, maternal satisfaction, and the need for mother-infant separation within the first 2 hours postpartum.

This randomized, single-center, single-masked clinical trial aims to compare the immunomodulatory effects of sevoflurane-based inhalational anesthesia and propofol-based total intravenous anesthesia in obese patients undergoing elective lumbar instrumentation surgery. Seventy patients will be randomized into two groups: a propofol group and a sevoflurane group. Blood samples will be collected preoperatively, at postoperative 6 hours, and at postoperative 24 hours. Pentraxin-3 and serum amyloid A levels will be evaluated as primary inflammatory biomarkers together with IL-6, TNF-α, CRP, glucose, and complete blood count parameters.
