Case Reports[Effectiveness of adenosine as a pulmonary vasodilator during weaning from extracorporeal circulation after mitral valve replacement in a patient with severe pulmonary hypertension].
A 75-year-old woman with mitral stenosis and tricuspid insufficiency underwent mitral valve replacement surgery. After insertion of a catheter into the pulmonary artery, upper respiratory system pressure was seen to rise above systemic arterial pressure. To relax the pulmonary vessel, we administered adenosine, a drug that is metabolized rapidly during its first pass through the lungs before hypotension or other adverse side effects occur systemically. Adenosine decreased pulmonary artery pressure and vascular resistance, optimizing right cardiac function with successful output to extracorporeal circulation.

Randomized Controlled Trial Clinical Trial[Comparative study of 3 techniques for total intravenous anesthesia: midazolam-ketamine, propofol-ketamine, and propofol-fentanyl].
To compare the characteristics of induction, maintenance and awakening for three techniques of combined total intravenous anesthesia (TIVA): propofol-ketamine, midazolam-ketamine and propofol-fentanyl. ⋯ TIVA with ketamine and propofol is comparable to the most commonly used combination of propofol and fentanyl and may be an appropriate choice when hemodynamic stability is of great importance; withdrawal 15 min before ending surgery prevents prolonged awakening. Perfusion of midazolam-ketamine is not recommendable for scheduled surgery because it induces too many hypertensive peaks. Although neither midazolam nor propofol completely prevents the psychomimetic effects of ketamine, such effects are not so severe that patients reject the anesthetic technique used.

Randomized Controlled Trial Clinical Trial[Conditions of intubation and neuromuscular block induced by mivacurium: comparison with succinylcholine].
To compare the clinical conditions for intubation and neuromuscular parameters after a high dose of mivacurium (0.25 mg/kg; 3 x SD95) administered in 30 s to those obtained after use of the usual dose of succinylcholine (1 mg/kg). ⋯ Given the moderate conditions of intubation achieved at 60 s, mivacurium can not be recommended as a relaxant in situations that require a rapid induction sequence. In elective surgery, 0.25 mg/kg of mivacurium can, however, be considered an alternative to succinylcholine.
