Despite stable background pain, most cancer patients suffer 3-4 episodes of breakthrough pain daily. Aim of the present study was the evaluation of potential correlation between effective doses of sublingual fentanyl citrate, administered for controlling breakthrough pain, with transdermal fentanyl used for background pain. Fifty-six cancer patients were prospectivelly recruited. All patients were suffering episodes of breakthrough pain and managed with transdermal fentanyl 25-300μg/h for their background pain.
Continue readingApneic oxygenation is an adjunct „ventilation‟ technique that involves insufflation of oxygen at varying flows through a catheter that is inserted through the endotra-cheal tube and is positioned above the carina. Apneic oxygenation improves gas exchange efficiency and preserves the arterial oxygenation at an acceptable level.

A ninety degrees anti-clockwise rotation (90ΑCWR) of the tube or cricoid cartilage pressure application (CCPA) was randomly performed in eighty patients undergoing fibreoptic orotracheal intubation under general anaesthesia, in whom first attempt to railroad the tracheal tube had failed.
Continue readingPulmonary capillary pressure (Pcp) is the primary driving force determining the fluid flux across pulmonary capillary wall. Alterations of Pcp have been described in systemic inflammation, sepsis, ARDS, hypoxaemia and acute heart failure. The purpose of this study was to examine the Pcp alterations after lipopolysaccharide (LPS) intravenous administration in pigs. LPS has been administered (150μg/Kg BW) in the right atrium of 8 anesthetized and mechanical ventilated pigs (Group A) and the Pcp was calculated from pulmonary artery pressure tracings using the Gaar equation before, after LPS infusion and in 20min intervals for two hours.
