Filter by:With blocks of lumbar and lumbar plexus, we can reduce the intravenous anesthetics usage. To offer an satisfied surgery process for patients, a proper sedation is necessary. So in this study, we want to investigate the influence of two different sedative drugs on outcomes of patients received hip replacement surgery .
The investigators will use health administrative data to examine the variation of anesthesia type for hip fracture surgery, as well as sources of variation and predictors of variation.
Adequate blood oxygenation and ventilation/perfusion matching should be the main goal of anaesthetic and intensive care management. At present, the sole method of improving gas exchange restricted by ventilation/perfusion mismatching is independent ventilation with two ventilators. Recently, however, a unique device has been developed, enabling ventilation of independent lungs in 1:1, 2:1, 3:1, and 5:1 proportions. The main goal of the study was to evaluate the device's utility, precision and impact on biomechanical lung parameters during thoracic surgery under general anaesthesia with double lumen tube intubation. Secondly- to measure the gas distribution in supine and lateral decubitus position.
Observational study evaluating effect general or regional anaesthesia on glycocalyx by using perfused Boundary Region in sublingual microcirculation.
Acute respiratory failure is frequent during rhythmology procedure under light sedation in high risks selected patients. Non invasive ventilation (NIV) is recommended for acute cardiogenic pulmonary oedema and sleep apnea. The investigators will perform a monocentric, prospective, randomized controlled trial to compare the efficacy of NIV which associated pressure support ventilation (PSV: 5 to 15 cmH2O) and positive end expiratory pressure (PEEP: 5 to 10 cmH2O) with standard oxygen therapy in prevention of peroperative respiratory event. Our hypothesis is that peroperative use of NIV should reduce the incidence of apnea and hypoxia during procedure in rhythmology under light sedation.
A correct preoxygenation can be obtained after a 3min delay of calm ventilation through a tight mask thereafter mask is used to make the patient breathing before intubation. Most tight masks are actually sold but they have never been compared in studies. The aim of this study is to compare air leaks with standard facial mask and QuadraLite masks during preoxygenation and induction of anesthesia.
Comparison of conventional assessment of anesthetic depth by anesthesiologists (moderate, deep or light anesthesia) with EEG monitoring (Narcotrend® state/index). In case of mismatch statistical analysis for underlying factors are done.
Introduction Several attempts have been made to improve or facilitate epidural space detection beside conventional loss of resistant technique. Recently many sophisticated equipment's and techniques have been described which did not received widespread popularity. Objectives The Investigator describes and assesses the validity of using Pressure Gauge Manometer to confirm correct detection of lumber epidural space, in an inexpensive way. Methods Tuohy needle is introduced into intervertebral space at the level of L3-L4 up to the interspinous ligaments ( nearly 2cm mark on the needle).A3-way stopcock is connected to the hub of Tuohy needle with the in-line port of the stopcock attached to an air-filled 10 ml syringe. Using a 75 cm extension tube set and create a 30 mm Hg pressure gradient between manometer and the tip of epidural needle , the needle is advanced slowly using both hands while monitoring the manometer reading and is stopped when the pressure suddenly dropped ( the pressure usually drops by 5-10 mm Hg when the tip of the needle inters the epidural space ).
Effects of different doses of remifentanil on hemodynamic response to anesthesia induction in elderly patients ABSTRACT OBJECTİVE: The investigators compared the effects of three different doses of remifentanil infusion, which have been performed for the induction of anesthesia in elder patients, on cardiovascular response. PATIENTS AND METHODS: The present study was designed as a randomized, prospective and double-blind study. A total of 90 ASA I-II patients over the age of 65 years were enrolled and each group consisted of 30 subjects. The patients were randomly (by lot) assigned to receive one of the three doses of remifentanil infusion (0.1, 0.2 or 0.3 µg/kg/min) for two minutes. Subsequently, 0.5 mg/kg propofol was administered via IV route and, 0.5 mg/kg rocuronium was administered via IV route at the time eyelash reflex disappeared. Intubation was performed after two minutes. After recording baseline values of heart rate (HR), systolic arterial pressure (SBP), diastolic arterial pressure (DBP) and mean arterial pressure (MAP), these values were recorded at the 1st, 2nd, 3rd, 4th and 5th minutes of induction.
The aim of this randomized trial will be to evaluate the clinical performance of the I-gel, air- Q ILA compared with the LMA classic in pediatric patients undergoing peripheral surgery under general anesthesia.
