Clinical trials

The aim of this prospective study is to evaluate the accuracy of artificial intelligence (AI) and machine learning algorithms in predicting difficult airways in patients undergoing bariatric surgery. Preoperative airway assessments, including the Upper Lip Bite Test (UBLT), Mallampati score, Body Mass Index (BMI), thyromental distance (TMD), and sternomental distance (SMD), will be recorded. The study investigates whether AI models can provide higher sensitivity and specificity in predicting difficult intubation compared to traditional clinical scoring systems in the obese patient population.

This retrospective observational study aims to evaluate the relationship between systemic inflammatory parameters, thyroid autoimmunity markers, and neuroretinal structures in patients with Graves disease. Medical records of patients diagnosed with Graves disease and healthy control subjects evaluated at Elazığ Fethi Sekin City Hospital between August 2018 and January 2026 will be reviewed. Optical coherence tomography (OCT) measurements, including macular thickness and peripapillary retinal nerve fiber layer (RNFL) thickness, will be analyzed. Laboratory parameters such as complete blood count-derived inflammatory indices, C-reactive protein, thyroid function tests, and thyroid autoantibodies will also be recorded. The study will compare neuroretinal parameters between healthy controls, Graves disease patients without ophthalmopathy, and Graves disease patients with ophthalmopathy, and will investigate potential associations between systemic inflammation, thyroid autoimmunity, and neuroretinal structural changes.

Decisions regarding tracheostomy and percutaneous endoscopic gastrostomy (PEG) in the intensive care unit (ICU) are frequently associated with substantial uncertainty, decisional conflict, and psychosocial burden among patients' relatives. Inadequate or non-tailored information may negatively influence anxiety levels, decision satisfaction, and subsequent adaptation to care responsibilities. Differences in communication patterns and educational background may further affect how families perceive the risks, benefits, and long-term implications of these procedures. This prospective study aims to evaluate the impact of relatives' educational level and different information delivery methods on anxiety, decision satisfaction, and the overall decision-making process related to tracheostomy and PEG in the ICU setting. The findings are expected to contribute to the development of structured, education-level-tailored information strategies to improve shared decision-making and family-centered care in critical care practice.

Study Design This retrospective observational study aims to evaluate and compare the effects of two regional anesthesia techniques, Erector Spinae Plane (ESP) block and Retrolaminar Block (RLB), on postoperative recovery quality in women undergoing elective cesarean section (CS). Postoperative pain after CS is common, particularly in the first 24-72 hours, and can affect mobility, breastfeeding, and overall well-being. Effective pain management is therefore critical for both patient comfort and maternal-infant bonding. Participants and Methods Medical records of adult women aged 18-45 years, with a singleton pregnancy at ≥37 weeks, who underwent elective CS under spinal anesthesia in our clinic, were retrospectively reviewed. Patients who had received either ESP or RLB immediately after surgery were included. Both blocks had been performed under ultrasound guidance at the T9 level using 20 mL of 0.25% bupivacaine, according to institutional practice. Standard perioperative care and analgesia protocols were applied to all patients. Outcomes The primary outcome was postoperative recovery quality, assessed 24 hours after surgery using the Turkish version of the Obstetric Quality-of-Recovery Score (ObsQoR-11T), a validated tool addressing physical, emotional, and functional aspects of recovery. Secondary outcomes included postoperative pain intensity (Visual Analog Scale), opioid consumption, adverse events, and patient satisfaction, as documented in patient files. Conclusion This retrospective study will provide evidence on which block technique more effectively improves recovery quality after CS and may help optimize postoperative analgesia strategies in Turkish obstetric populations.

The purpose of this prospective, observational study is to evaluate the effect of retrolaminar block (RLB) on patient comfort and analgesic effectiveness during extracorporeal shock wave lithotripsy (ESWL) procedures. The main questions the study aims to answer are: Does retrolaminar block reduce pain intensity during ESWL? Does retrolaminar block improve patient comfort during ESWL? Participants will undergo the following interventions: RLB Group: Retrolaminar block performed under ultrasound guidance prior to ESWL. Sedation Group (S): Standard sedoanalgesia administered. Control Group (C): No additional regional block or sedoanalgesia applied. Participants will be monitored for pain levels, procedural duration, hemodynamic parameters, and the need for additional analgesics. The study aims to determine whether retrolaminar block can serve as a safe and effective analgesic method during ESWL procedures.

This prospective clinical study aims to evaluate the effect of Transversus Abdominis Plane (TAP) block on postoperative gastrointestinal function in patients undergoing laparoscopic sleeve gastrectomy. Gastrointestinal recovery plays a crucial role in patient outcomes after bariatric surgery, and regional anesthesia techniques such as TAP block have been suggested to reduce postoperative pain and opioid consumption, which may influence gut motility. In this study, postoperative gastrointestinal function will be assessed using the validated Patient-Reported Outcome for Dysfunctional Gastrointestinal Motility (PRO-diGI) scale. Additionally, gastric ultrasound will be performed to calculate the Perlas score as an objective marker of gastric emptying and residual volume. These assessments will allow a comprehensive evaluation of both subjective and objective gastrointestinal recovery parameters. The study will include adult patients scheduled for elective laparoscopic sleeve gastrectomy at Elazığ Fethi Sekin City Hospital. Participants will receive standard general anesthesia with or without ultrasound-guided TAP block, and their postoperative recovery will be monitored. Primary outcomes include PRO-diGI scores at defined postoperative intervals, while secondary outcomes include Perlas scores obtained via gastric ultrasonography. The findings from this research are expected to provide valuable insights into the potential benefits of TAP block on gastrointestinal motility and overall recovery after bariatric surgery.

Laminectomy surgeries, typically performed for lumbar disc herniation and spinal disorders, are often lengthy surgical procedures requiring patients to be in the prone position. While this position provides better visibility of the surgical field, it can lead to physiological changes in intraocular pressure (IOP) in anesthetized patients. An increase in IOP, though rare, has the potential to cause severe ocular complications such as postoperative vision loss (POVL), which is one of the most feared complications after spinal surgery. One of the main mechanisms of IOP elevation in the prone position is the impediment of venous return in the head and neck region due to gravity, leading to an increase in episcleral venous pressure. Additionally, direct mechanical pressure on the face and globe can also increase IOP. Anesthesia management can also play a role in IOP dynamics by affecting intrathoracic pressure and venous return. This complex interaction necessitates careful monitoring of eye health in anesthetized patients in the prone position. Non-contact tonometers offer a non-invasive, rapid, and reliable method for IOP measurement. They are particularly advantageous for repeated measurements in anesthetized patients. This clinical study aims to evaluate changes in IOP using a non-contact tonometer in patients undergoing laminectomy in the prone position and to identify anesthesia- and patient-related factors influencing these changes. The data obtained will contribute to the development of anesthesia and positioning strategies aimed at reducing the risk of ocular complications.
