Clinical trials

This retrospective observational study aims to evaluate the clinical characteristics and in-hospital outcomes of critically ill adult patients who underwent hemodialysis (HD) or continuous venovenous hemodiafiltration (CVVHDF) in the Emergency Department of Antalya Training and Research Hospital between January 1, 2023, and August 1, 2026. Medical records will be reviewed to collect information on patient demographics, comorbidities, clinical findings at admission, vital signs, renal replacement therapy indications, laboratory results before and after treatment, treatment modality, treatment-related complications, need for intubation or vasopressor/inotropic support, intensive care unit admission, length of stay, and hospital outcomes. The primary outcome is in-hospital mortality. Secondary outcomes include emergency department mortality, intensive care unit admission, ward admission, discharge status, emergency department and hospital length of stay, need for intubation or vasopressor/inotropic support, treatment completion, treatment-related complications, and changes in laboratory parameters before and after renal replacement therapy. No additional intervention, test, treatment, or biological sample collection will be performed as part of this study.

Ultrasound-guided internal jugular vein (IJV) catheterization is widely used in critically ill patients. Despite ultrasound guidance, difficult catheterization and first-pass failure remain clinically important and may increase the risk of mechanical complications. Pre-procedural characteristics of the IJV, its anatomical relationship with the common carotid artery (CCA), head rotation, and operator experience may influence procedural success. The ROTATE-ICU study is a prospective observational cohort study designed to investigate pre-procedural ultrasound and clinical predictors of difficult IJV catheterization in critically ill adults. Consecutive adult intensive care unit patients undergoing ultrasound-guided IJV central venous catheterization will undergo standardized pre-procedural ultrasound assessment. IJV anterior-posterior diameter, skin-to-vessel depth, IJV position relative to the CCA, head rotation angle, operator experience, and relevant clinical and procedural characteristics will be recorded. The primary objective is to develop and internally validate a clinical prediction model for cannulation difficulty and first-pass cannulation outcome. Secondary objectives include evaluating the relationship between head rotation and IJV morphology and describing the association between complete IJV collapse and procedural outcomes. The planned enrollment is 150 participants.

This study aims to interpret the Bispectral Index (BIS) monitoring method, which we routinely use for monitoring in scoliosis surgery, with artificial intelligence (AI) tools and to determine the accuracy and reliability of AI tools in clinical practice by comparing this interpretation with the interpretations of two clinicians experienced in BIS.

The aim of the present study is to test the accuracy and reliability of AI tools in this regard by interpreting NIRS, which we routinely use for monitoring cerebral perfusion in cardiovascular surgery, with AI tools and comparing this interpretation with the interpretations of two clinicians.

The aim of this study is to evaluate the levels of systemic inflammatory markers such as PIV, SII, and NPAR in patients with benign and premalignant laryngeal lesions and to determine the diagnostic accuracy of these values using ROC analysis.

Acute pancreatitis is an important gastrointestinal emergency that may lead to mortality, particularly in older patients. This retrospective, single-center observational prognostic validation study aims to compare the predictive performance of the National Early Warning Score 2 (NEWS-2) and NEWS-Calcium scores for in-hospital mortality in patients aged 65 years and older diagnosed with acute pancreatitis in the emergency department. Electronic medical records of eligible patients will be reviewed retrospectively. Demographic characteristics, vital signs, serum calcium levels, clinical outcomes, intensive care unit admission, organ failure, length of hospital stay, and in-hospital mortality will be recorded. NEWS-2 will be calculated using vital parameters at admission, while the NEWS-Calcium score will be obtained by adding a calcium-based score to NEWS-2. The primary outcome will be in-hospital mortality. Secondary outcomes will include intensive care unit admission, severe acute pancreatitis, persistent organ failure, and length of hospital stay. The predictive performances of the scores will be compared using ROC curve analysis, AUC values, and the DeLong test. This study aims to identify the most appropriate early prognostic score for older patients with acute pancreatitis and to support clinical decision-making in emergency settings.

The aim of this study is to determine the usability of echocardiographic PAP changes obtained from emergency department records in the early risk stratification of pulmonary embolism.

The aim of the present study is to evaluate the effects of the recto-intercostal fascial plane block (RIFPB) or the rectus sheath block (RSB) combined with the pectoral-intercostal fascial plane block (PIFPB) on postoperative analgesia in patients undergoing cardiac surgery.
