Filter by:IIn this study, the investigators planned to investigate effectiveness of supplemental oxygen in patients (18-65 years) who were diagnosed as headache related to migraine without aura in the emergency department (ED). Patients who will be ordered standard migraine therapy (50 mg dexketoprofen and 10 mg metoclopramide HCl in 100 cc normal saline IV) by the physician blind to research, will be evaluated by the researchers before the treatment and patients met the study criteria will be included. Included patients randomly divided to two group, study group will receive supplemental oxygen with face mask for 1 hour. Patients' visual analog score (VAS) will be measured at 0th, 15th, 30th and 60th minute of treatment. If there will not be a 50% decrease at VAS score from the beginning, patients will be examined again by the physician again. Patients who will be ordered 100 mg tramadol as rescue therapy by the physician, will be continued to observed, VAS scores will be measured at 120th minute again. To avoid drug related bias, patients who will be ordered any other drug for primary care or rescue treatment other than mentioned above will not be included into the study.
Endoscopic microsurgical procedures of the larynx (direct examination-bx, microlaryngeal resection) require the anesthesiologist and surgeon to work in the same area throughout the procedure, and while ventilation is provided during the procedure, small diameter endotracheal tubes are preferred to see the surgical area as easily as possible. However, it is sometimes observed that even conventional endotracheal tubes of this diameter make surgery difficult by obstructing the view. On the other hand, apneic laryngoscopy techniques used in upper airway surgeries, such as microlaryngoscopy and laryngotracheal surgery, where the airway is shared by the anesthesiologist and surgeon, have been replaced by safer and controlled high-frequency jet ventilation applications due to the risk of hypoxemia and hypercapnia. In recent years, oxygenation has come to the fore with Transnasal High Flow Insufflation (OptiflowTM - Fischer & Paykel Healthcare, Auckland, New Zealand), an apneic oxygenation method. This randomized study aimed to compare the effects of high-flow nasal oxygen and jet ventilation on oxygenation in patients receiving general anaesthesia for endolaryngeal surgery.
This study will describe the change of mitochondrial oxygen tension (mitoPO2) compared to traditional parameters of oxygenation and oxygen balance in the first 24 hours of septic patients admitted to the intensive care unit of an academic hospital. The mitoPO2 will be measured on prespecified measurement moments in the ICU. With each measurement moment, arterial and central venous blood gasses will be taken too.
