Considering the growing trend of laryngeal surgeries and the need to protect the airway during and after surgery, among several therapeutic regimens to induce sedation, two regimens of propofol-fentanyl and propofol-midazolam were compared in microlaryngeal surgeries. Forty ASA I-II class patients undergoing microlaryngeal surgeries and referring routinely for postoperative visits were randomly...

Introduction: Cataract surgery is a common surgery, especially among the elderly, and the choice of anesthesia medications is critical in such patients. In this study, the effects of midazolam, propofol, and dexmedetomidine were investigated for sedation in patients undergoing cataract surgery under local anesthesia. Method: Ninety patients were included in this study and underwent cataract su...

BACKGROUND Airway clearance techniques include positive expiratory pressure, commonly used in our clinical practice, and a recently introduced temporary positive expiratory pressure device called UNIKO®. It is unclear which one provides the best benefit to patients. OBJECTIVES The aim of this observational 4-year study was to retrospectively compare the efficacy of and specific indications fo...

INTRODUCTION Maintaining arterial blood glucose within tight limits is beneficial in critically ill patients. Upper and lower limits of detrimental blood glucose levels must be determined. METHODS In 69 patients with severe traumatic brain injury (TBI), cerebral metabolism was monitored by assessing changes in arterial and jugular venous blood at normocarbia (partial arterial pressure of carb...

Oxygen diffusion across the alveolar wall is compromised by low alveolar oxygen but also by pulmonary edema, and leads to hypoxemia and hypoxic pulmonary vasoconstriction (HPV). To test, whether inhibition of alveolar fluid reabsorption results in an increased pulmonary arterial pressure and whether this effect enhances HPV, we established a model, where anesthetized rats were ventilated with n...

A micro-oxygen sensor was used to monitor the optic-disk oxygen tension in vivo in the cat. The perfusion pressure of the eye, defined as the systemic arterial blood pressure minus the intraocular pressure, was decreased. This was accomplished both by lowering the systemic arterial blood pressure by increasing the expiratory resistance and by elevating the intraocular pressure. The result of lo...
