Introduction:
Hyperventilation has been used for intraoperative brain relaxation for decades, Interestingly, this common practice is not based on robust evidence .
The mechanism of brain relaxation secondary to hyperventilation is attributed to the hypocapnia induced cerebral vasoconstriction and
Radiotherapy (RT) has an established role in breast cancer, complementing surgery and systemic therapies to prevent recurrences and improve survival. Long-Term follow-up shows that the beneficial effect on survival is weakened by radiation-induced cardiac and lung cancer mortality, especially in
The role of mechanical ventilation in patients undergoing general anesthesia is worldwide well known but it has been associated with dangerous effects such as pulmonary complications, increasing postoperative morbidity and mortality. Lung-protective ventilation using low tidal volume and positive
Aim
The investigators wish to study the inflammatory response in very well-trained and relatively untrained healthy volunteers using the human endotoxemia model. Also, the investigators wish to study the effect on nicotine on the inflammatory response..
Background
1. Systemic inflammation and the
Background
During facial cooling and especially during breath hold, can mammals - and also humans - elicit a so called dive reflex, causing bradycardia, peripheral vasoconstriction and centralization of blood flow to brain, lungs and heart (18 Foster et al 2005), but the reflex is suppressed by
