noradrenaline/hypoxia

Hypothesis Stellate ganglion blockade in patients with moderate and severe brain damage: 1. Increases the diameter of the brain arteries and blood flow through the brain 2. Do not interfere with intracranial pressure 3. Reduces aseptic inflammatory reaction of the damaged brains measured by IL-6 and

Pneumoperitonium for laproscopic surgery usually result in decrease total respiratory compliance due to cranial shift of the diaphragm. Alveolar recuirtment is applied hopefully to minimize lung atlectasis and open collapsed alveoli to maintain arterial oxygenation. The anantomical proximity of

The dogma over the past 3 decades, particularly in the field of sleep medicine, has been that intermittent hypoxia (IH) is a detrimental stimulus that leads to a number of co‐morbidities including autonomic (e.g. increased sympathetic nervous system activity), cardiovascular (e.g. hypertension,

With no premedication, all patients will have pre-oxygenation for 3-5 minutes and intravenous access will be secured. NaCl 0.9% 4 ml/kg/h will be infused intraoperatively. General anesthesia will be induced by fentanyl 1 ug/kg, propofol 2 mg/kg and nimbex (cisatracurium) 0.15 mg/kg. Endotracheal

I. Background Excessive fluid loss is often reported in gastrointestinal surgical patients due to preoperative fasting and bowel preparations. Many factors may further exacerbate the lack of fluid volume, including intraoperative blood loss and fluid loss, anesthetic drug-induced peripheral

Background of the study: Morbidly obese patients selected for elective bariatric surgery have major anesthetic concerns. The risks include a difficult airway, difficult mask ventilation, hypoxemia, pre-existent restrictive and obstructive lung disease and residual anesthetics postoperatively due to

Study aim A: Red cell mass and hypoxia: Various forms of altitude training have been used to increase in particular endurance performance of elite athletes. The most commonly used approaches is either to live and train at altitude (Live high - train high; LHTH) or to live at high altitude while
