Clinical trials

This study aims to evaluate the effect of operating room orientation video education delivered at different time points on postoperative pain and state anxiety in patients undergoing surgery for benign prostatic hyperplasia. Patients undergoing transurethral resection of the prostate or holmium laser enucleation of the prostate will be randomly assigned to one of three groups: video education one day before surgery in the surgical ward, video education approximately 30 minutes before surgery in the operating room waiting unit, or routine preoperative information. Pain and state anxiety will be assessed at predefined preoperative and postoperative time points.

This study aims to compare the analgesic effects of the serratus posterior superior intercostal plane block and intrathecal morphine in patients undergoing video-assisted thoracoscopic surgery. This is a prospective, randomized, controlled, single-center clinical trial including adult patients undergoing elective thoracoscopic surgery. Participants will be randomly assigned to receive either a serratus posterior superior intercostal plane block or intrathecal morphine before general anesthesia. The primary outcome is cumulative opioid consumption during the first 24 postoperative hours, expressed as intravenous morphine milligram equivalents. Secondary outcomes include pain scores, time to first analgesic request, quality of recovery, and postoperative complications. The study aims to determine whether these two techniques differ in their effectiveness for postoperative pain management.

This prospective observational cohort study aims to evaluate the prognostic value of multimodal nutritional status and sarcopenia assessment in patients undergoing lung cancer surgery. Postoperative complications, mortality, and prolonged hospital stay remain major clinical concerns in thoracic surgery. Although malnutrition and sarcopenia are recognized as important determinants of surgical outcomes, their combined and multidimensional evaluation has not been sufficiently studied. Adult patients undergoing anatomical lung resection for primary lung cancer will be included. Nutritional status will be assessed using serum biomarkers, inflammatory indices, and validated clinical nutritional scores. Sarcopenia will be evaluated using computed tomography-based muscle mass and density measurements, as well as ultrasonographic muscle thickness. These parameters will be analyzed in relation to postoperative complications, intensive care unit (ICU) requirement, length of hospital stay, and mortality. Multivariable analyses will be performed to identify independent predictors, and a combined risk stratification model will be developed. This study aims to improve preoperative risk assessment and to support personalized perioperative management strategies, including identification of patients who may benefit from targeted nutritional optimization and prehabilitation.

This study aims to examine the effect of using the Patient Safety Checklist (PASC) on surgical patients' satisfaction with discharge education and their communication-related issues. This study is designed as a post-test control group randomized trial. The main questions it aims to answer are: H₀₁: There is no difference in discharge education satisfaction levels between surgical patients who use the PASC and those in the control group. H₀₂: There is no difference in communication problems between surgical patients who use the PASC and those in the control group. •H₁₁: There is a difference in discharge education satisfaction levels between surgical patients who use the PASC and those in the control group. H₁₂: There is a difference in communication problems between surgical patients who use the PASC and those in the control group. Research Question:• What are the adherence rates for each item of the PASC Checklist and the overall adherence rate among participants? Participants will: * From the day the decision for surgery is made until hospital discharge, participants will either use the Patient Safety Checklist (PASC) or receive standard perioperative care, according to their group allocation. * On the day of discharge, participants will complete the Surgical Patients' Discharge Education Satisfaction Scale, the Healthcare Communication Questionnaire, and the Health Communication Problems Scale.

Effective postoperative analgesia after cesarean delivery is essential for maternal recovery, early mobilization, breastfeeding, and maternal-infant bonding. Although intrathecal morphine (ITM) is considered the gold standard for post-cesarean analgesia, its use is associated with opioid-related adverse effects. Ultrasound-guided lateral quadratus lumborum block (QLB-I) has emerged as a promising alternative. This randomized, double-blind, non-inferiority trial aims to compare the postoperative analgesic efficacy of lateral QLB-I with ITM. Secondary outcomes include postoperative opioid consumption, pain scores, opioid-related adverse effects, quality of recovery (ObsQoR-11T), and maternal satisfaction.

This prospective randomized controlled trial aims to compare the hemodynamic and pulmonary effects of single-step and stepwise lung recruitment maneuvers in adult patients undergoing elective cardiac surgery with cardiopulmonary bypass. After separation from cardiopulmonary bypass, patients will be randomized to receive either a single-step sustained inflation recruitment maneuver or a stepwise incremental recruitment maneuver, both combined with 8 cmH₂O positive end-expiratory pressure. The primary outcome is the change in cardiac index before and after the recruitment maneuver. Secondary outcomes include lung ultrasound atelectasis score, and hemodynamic parameters.

The aim of this study is to investigate the efficacy of bilateral serratus posterior superior intercostal plane (SPSIP) block on postoperative acute pain and opioid consumption in patients undergoing on-pump open-heart surgery. Postoperative outcomes including pain scores, cumulative morphine use, quality of recovery, and opioid-related side effects will be evaluated within the first 24 hours after surgery.

Menopause is a natural life stage associated with hormonal changes that may affect women physically and psychologically. During this period, women may experience increased stress levels, negative attitudes toward menopause, and decreased mindfulness. Mandala coloring is a structured art-based intervention that may promote relaxation and improve psychological well-being. This randomized controlled trial aims to evaluate the effect of mandala coloring on attitudes toward menopause, perceived stress, and mindfulness levels among menopausal women.

The purpose of this clinical trial is to evaluate whether two different analgesic techniques - ultrasound-guided Transversalis Fascia Plane Block (TFPB) and surgical wound infiltration - can improve postoperative pain control in adult patients undergoing open inguinal hernia repair. The key questions that this study aims to answer are: Does TFPB reduce total intravenous opioid consumption within the first 24 postoperative hours compared with wound infiltration? Does TFPB improve postoperative pain scores at rest and during movement compared with wound infiltration? Does TFPB improve patient satisfaction, reduce the need for rescue analgesics, and enhance overall postoperative recovery quality? If there is a comparison group: The investigators will compare the effects of TFPB with wound infiltration to determine whether either technique provides superior postoperative analgesia and reduces opioid requirements. Participants will be asked to: Undergo open inguinal hernia repair under spinal anesthesia. Be randomly assigned to one of two groups: TFPB Group: Receive an ultrasound-guided transversalis fascia plane block with local anesthetic. Wound Infiltration Group: Receive local anesthetic infiltration performed by the surgeon along the incision line. Postoperatively: Report pain scores at defined intervals. Receive standardized IV analgesia with documentation of opioid consumption. Allow assessment of rescue analgesic requirement. Be monitored for adverse events and recovery outcomes.

In this retrospective study, the effect of intraoperative magnesium sulfate infusion on the incidence of postoperative emergence agitation was evaluated in adult patients who underwent elective lumbar microdiscectomy under general anesthesia. The medical records of patients aged 18-70 years with an ASA physical status of I-II were retrospectively reviewed. Patients were evaluated according to whether they received intraoperative magnesium sulfate infusion as part of anesthetic management. The primary outcome measure was the incidence of emergence agitation in the post-anesthesia care unit; this assessment was based on Ramsay Sedation Scale scores recorded in the post-anesthesia care unit at admission and at 5, 10, 15, and 30 minutes. Secondary outcome measures included postoperative pain scores assessed using the Numeric Rating Scale, intraoperative remifentanil consumption, recovery and extubation times, tramadol requirement in the post-anesthesia care unit, and possible adverse events related to magnesium infusion.

Intravenous (IV) fluids-fluids given directly into a vein-are among the most common treatments used in intensive care units (ICUs). They are given for several reasons, such as supporting blood pressure, providing daily water and salts, replacing losses, or diluting medications. However, the type of fluid, the amount given, and the salt (sodium and chloride) load can vary widely between hospitals and doctors. In Turkey, there is currently no up-to-date, multicenter information describing how IV fluids are used in adult ICUs in everyday practice. This study, called TR-FLUID, aims to describe IV fluid use in adult ICUs across Turkey. It is an observational study, meaning the researchers only observe and record care that is already being provided. No extra tests, medications, or procedures are added, and the study does not change how patients are treated in any way. On a single pre-selected study day at each participating ICU, the research team will identify all adult patients (18 years and older) who are in the ICU at 8:00 a.m. For each patient, the team will record the IV fluids given over the following 24 hours-including the fluid type, the volume, the reason it was given, and the resulting sodium and chloride load-together with the patient's fluid balance. All information is taken from the patient's existing medical records. The main goal is to determine what proportion of patients receive fluids for resuscitation and which fluid types are used. The study will also describe the total fluid, sodium, and chloride given by indication; the 24-hour fluid balance; and how fluid use relates to short-term events such as the need for blood-pressure-supporting medications, new kidney injury, and ICU and hospital survival. These relationships will be explored to generate hypotheses and are not intended to prove cause and effect. The findings will provide a national picture of current fluid practice in Turkish ICUs, help identify where practice differs from guidelines, and serve as a foundation for future quality-improvement and research efforts.

This study investigates whether Body Roundness Index (BRI), an anthropometric measure derived from waist circumference and height, can predict mortality in adult intensive care unit (ICU) patients. BRI captures central adiposity and body fat distribution more accurately than Body Mass Index (BMI). In this prospective multicenter cohort study, BRI will be measured at ICU admission and its association with ICU mortality, 28-day mortality, hospital mortality, mechanical ventilation duration, ICU length of stay, and acute kidney injury will be evaluated. The predictive performance of BRI will also be compared with BMI.

There is a need for studies that examine the role of dual-task cost in predicting fall risk among older adults receiving institutional care and that develop classification models that can be used in clinical practice. The planned study aims to determine the discriminative ability of dual-task cost in identifying fall risk and to establish clinically meaningful cutoff values. In this respect, the study will both contribute to a more sensitive assessment of fall risk and provide a scientific basis for a low-cost, practical, and applicable screening approach.

The goal of this observational study is to determine whether the rate of prostate tissue removed during surgery relative to the preoperative total prostate volume (referred to as the "enucleation ratio") predicts symptomatic improvement 3 months after HoLEP. The main question it aims to answer is: \- What is the minimum enucleation ratio required to achieve clinically important symptomatic improvement? (Symptomatic improvement is referred to as a threshold of having an International Prostate Symptom Score (IPSS) lower than 8 points, which is determined by the American Urological Association (AUA) and European Association of Urology(EAU)).

This study aims to evaluate the effect of non-surgical periodontal therapy on serum asprosin levels in patients with stable angina and periodontitis. Asprosin is a novel metabolic biomarker reported to have potential protective roles in cardiovascular diseases and inflammatory processes. The study also investigates the relationship between periodontal parameters and serum asprosin levels before and after periodontal therapy.

1. What is this study about, and why is it required? The goal of this observational study is to learn if anesthesia type (e.g., general anesthesia, spinal anesthesia) affects the safety and efficiency of HoLEP surgery. The main question it aims to answer is: \- Is a particular type of anesthesia related to less or more bleeding during the surgery? 2. What will be assessed to answer the main question of this study? (Outcome measure(s)) 2.1. Primary outcome measure of this study is: \- Change in the hemoglobin level perioperatively. 2.2. Secondary outcome measures are: * Requirement for the usage of any vasoactive medication due to low blood pressure * Time passed until discharge. * Time passed until the removal of the bladder drainage catheter. * Ratio of the unwanted events that require additional intervention other than medication, fluids, or blood transfusions (Complications, Clavien-Dindo Grade III or higher). * International symptom questionnaire score 3 months after surgery. * Quality of life (QoL) score 3 months after surgery. * Peak urinary current velocity (Qmax) and post-void residual volume measurement 3 months after surgery. 3. Can anyone participate in this study? Voluntary participants should meet the following criteria: * Being older than 18 years old. * Having bothersome lower urinary tract symptoms due to prostatic enlargement requiring surgical treatment. * Having no untreated or uncontrolled systemic disease, which refers to having an ASA (American Society of Anesthesiologists Physical Status Classification System) score III at most.

The aim of this study was to determine the effects of postoperative methods on nausea, thirst and comfort levels of patients undergoing spinal surgery.

This study aims to investigate the mediating role of kinesiophobia in the relationship between pain intensity and disability in individuals with chronic neck pain. Chronic neck pain is a multidimensional clinical condition influenced not only by biological factors but also by psychological components such as fear of movement. Understanding the mechanisms underlying disability may contribute to more targeted rehabilitation strategies. Participants with chronic neck pain lasting at least three months will be assessed using validated self-report questionnaires measuring pain intensity, kinesiophobia, disability, and physical activity levels.

This randomized controlled trial aims to evaluate the effects of pranayama and pursed-lip breathing exercises on postoperative pain, anxiety, and vital signs in patients undergoing breast surgery. Postoperative pain and anxiety are common problems that can negatively affect recovery, physiological stability, and overall well-being. Non-pharmacological interventions such as breathing exercises may help reduce these adverse outcomes and support recovery. Participants will be randomly assigned to one of three groups: a pranayama breathing exercise group, a pursed-lip breathing exercise group, or a control group receiving routine postoperative care. Breathing exercises will be performed three times daily for five minutes. Outcomes including pain, anxiety, and vital signs will be measured at baseline (pretest), postoperative day 1, and postoperative day 2. The findings of this study are expected to provide evidence on the effectiveness of breathing exercises as supportive nursing interventions in the postoperative care of breast surgery patients.

The goal of this observational study is to compare the performance of clinicians with different experience levels and a deep learning-based artificial intelligence (AI) model in assessing gingival phenotype using two diagnostic methods: the periodontal probe transparency method and visual assessment from standardized clinical photographs. The main questions the study aims to answer are: Can AI achieve comparable accuracy to human examiners in both probe transparency and visual assessment methods? Does examiner experience level influence diagnostic performance and agreement with the reference standard in these methods? Researchers will compare AI, dental students, and periodontology research assistants to determine accuracy, sensitivity, specificity, and agreement with the gold standard for each method. Participants will: Undergo standardized intraoral photography of maxillary anterior teeth, with and without a periodontal probe in place, following a validated protocol. Have gingival phenotype determined by a reference periodontologist using the probe transparency method as the gold standard. Have their photographs evaluated by AI, dental students, and research assistants for phenotype classification using both methods.

This study aims to examine the knowledge levels and attitudes of students enrolled in departments other than Audiology within the Faculty of Health Sciences regarding hearing loss and the use of hearing aids. This study is a descriptive. The study included students enrolled in the Faculty of Health Sciences at Ondokuz Mayıs University. Data will collect using the "Hearing Loss and Hearing Aid Knowledge and Attitudes Questionnaire Among Faculty of Health Sciences Students," which consisted of 29 items. The One-Way ANOVA test was used to compare quantitative variables between groups.

The goal of this clinical trial is to learn whether a needle-free injection system can make tooth extraction less stressful for children than a conventional dental syringe. The study will include healthy children 6 to 12 years old who need a primary tooth extraction with buccal and lingual local anesthesia. The main questions are whether the needle-free method can lower anxiety, lower pain, and reduce changes in vital signs compared with the conventional syringe. Researchers will randomly assign participants to 1 of 2 groups. One group will receive local anesthesia with a needle-free jet injection system. The other group will receive local anesthesia with a conventional syringe and a 27-gauge dental needle. In both groups, a topical lidocaine spray will be used before the injection, and the same anesthetic solution will be given. All tooth extractions will be performed by the same clinician using standard clinical procedures. Participants' anxiety, pain, and vital signs will be checked before the procedure, after anesthesia, and after tooth extraction. Anxiety will be measured with the Face Image Scale (FIS). Pain will be measured with the Face, Legs, Activity, Cry, Consolability (FLACC) scale and the Wong-Baker Faces Pain Rating Scale (WBS). Vital signs will include systolic and diastolic blood pressure, heart rate, and oxygen saturation. No blood, saliva, or tissue samples will be collected, and no audio or video recording will be made.

This study aimed to investigate whether the biomarkers GFAP, NfL, and VEGF-recently considered important guides for better understanding the pathophysiology of MS-also serve as indicators of clinical progression in MS.
