Clinical trials

The maxillary nerve block is a regional anesthetic technique targeting the sensory distribution of the maxillary nerve and is particularly preferred to provide analgesia in midfacial and maxillary surgical procedures. It has been used to optimize perioperative and postoperative pain control, reduce intraoperative opioid requirements, and support hemodynamic stability in procedures including septorhinoplasty, nasal bone osteotomies, nasal valve surgery, and endoscopic sinus surgery. This study aimed to compare the effects of the timing of bilateral maxillary nerve block administration (post-intubation vs. pre-extubation) on intraoperative remifentanil consumption and postoperative analgesia in patients undergoing septorhinoplasty.

Interscalene block is widely accepted as the gold-standard regional analgesic technique for pain control after arthroscopic shoulder surgery. However, because this block is performed at the level of the brachial plexus roots, it may be associated with adverse effects such as phrenic nerve blockade and subsequent diaphragmatic dysfunction. These limitations have prompted the search for alternative regional anesthesia techniques that can provide effective postoperative analgesia while preserving respiratory function. The anterior suprascapular block, which covers a broad dermatomal distribution of the shoulder region, has been shown in some studies to provide sufficient analgesia as a standalone technique. In addition, the pericapsular nerve group (PENG) block of the shoulder-applied around the anterior capsule and performed at a distance from critical neurovascular structures that may lead to serious complications-may represent another potential analgesic option following arthroscopic shoulder procedures. Therefore, this study aims to evaluate alternative regional block techniques in comparison with the interscalene block and to contribute to the identification of an optimal analgesic strategy after arthroscopic shoulder surgery.

This study aims to investigate the potential factors contributing to the development of Acute Kidney Injury (AKI) in patients undergoing pulmonary resection with Video Assisted Thoracoscopic Surgery (VATS) for lung malignancy. The study will focus on demographic data, laboratory parameters, perioperative fluid management, and haemodynamics. The research will be conducted at SBÜ Ankara Atatürk Sanatorium Training and Research Hospital. The study will involve patients who have given informed consent and will undergo VATS with standard anaesthesia monitoring. Anaesthesia management will follow our routine protocol in our clinic. Patients will be divided into two groups based on whether they have a more than 25% decrease in estimated glomerular filtration rate (t-GFH) and/or a 1.5-fold increase in serum creatinine and/or a 6-hour urine volume of less than 0.5 ml/kg/h. The patients will be divided into two groups based on this definition, and the risk factors between these groups will be analysed. The preoperative routine blood values, demographic data (age, gender, height, weight, and BMI), ASA physical status, smoking and alcohol habits, comorbidities, and regular medication use will be recorded. Intraoperative urine output and haemodynamic parameters will also be monitored. Routine blood gas analysis, blood urea nitrogen (BUN), glomerular filtration rate (GFR), albumin, haemoglobin, sodium, potassium, chlorine, and magnesium will be measured and recorded, along with urine output and t-GFH. Patients will be evaluated in the hospital on the day the surgeon calls for a postoperative check-up and on the 30th postoperative day to see if there are any complications.

Difficult airway management remains the leading cause of anaesthesia-related morbidity and mortality. Obstructive sleep apnea syndrome (OSAS) is a warning sign of difficult airway management. Polysomnography is the gold standard for diagnosis of this syndrome, but the STOP-BANG questionnaire is the preferred screening test. In this study, we wanted to find an answer to the question How successful is the STOP-BANG questionnaire in screening for obstructive sleep apnea syndrome (OSAS) in predicting OSAS, difficult mask and difficult intubation in patients undergoing thoracic surgery?
