This study compares the cardiovascular effects of spinal levobubivacaine or ropivacaine, in equipotent doses, for endoscopic urologic surgery. Eighty elderly, hypertensive patients, with physical status ASA I-III, scheduled to undergo transurethral procedures, were randomly allocated to receive spinal anesthesia with either 15 mg of levobupivacaine or 22.5mg of ropivacaine, in hyperbaric solutions.

The aim of our study was to compare video laryngoscopy and direct laryngoscopy views, and the resultant intubation conditions as well, provided by video or conventional laryngoscope respectively, in patients receiving general anaesthesia for elective surgery. One hundred patients, with no expected difficult airway, were randomly allocated to undergo tracheal intubation with the Macintosh video laryngoscope or a conventional Macintosh laryngoscope.

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 readingNSAIDs are widely used compounds in the management of several acute and chronic pain syndromes. NSAIDs induce their action by blocking the cyclooxygenase enzymes, cox-1 and cox-2, during the conversion of arachidonic acid to prostaglandins. Conventional NSAIDs inhibit both cox isoforms and are therefore at risk of serious complications as gastrointestinal irritation, postoperative bleeding, renal failure, water and sodium retention and hepatic failure.
Continue readingSince its identification as the active metabolite of nitroglycerin identical to endothelium derived relaxing factor, in mid-eighties, nitric oxide has been found over-all distributed in all body tissues implicated in many normal functions as well as pathophysiologic states, so that it has been aptly called biological jack-ofall- trades.
Continue readingGabapentin was tested as complementary analgesic in 25 cancer patients in whom pain was not sufficiently controlled by transdermal fentanyl. Neuropathic pain syndrome in these patients consisted of burning pain and allodynia. Gabapentin was administered at a dose of 648±206,4mg, while dosage of transdermal fentanyl was fixed (261±98,1μg/h).
