Nicotine has been reported to have analgesic effects in animal and human studies. This study evaluated the effect of pre-emptive use of transdermal nicotine patch on intraoperative sevoflurane and fentanyl requirements, perioperative haemodynamics and postoperative analgesia in patients undergoing lumber disc surgery. Fifty non-smokers patients (ASA I and II) undergoing lumber discectomy were r...
OBJECTIVES A potential problem in aortic valve replacement (AVR) for patients with a small aortic annulus is prosthesis-patient mismatch (PPM). Although larger size prostheses have been well studied, the haemodynamics of 19-mm bioprostheses has been reported in only a small number of patients. The Trifecta valve is a novel bioprosthesis and its unique design is conceived to increase effective o...

The Circle of Willis (CoW) is a ring-like structure of blood vessels found at the base of the brain. Its main function is to distribute a constant flow oxygen-rich arterial blood to the cerebral mass, despite changes in afferent pressures or flows. This objective is achieved by a local mechanism known as autoregulation, whereby the resistance in small vessels branching from the CoW changes by v...
