Anesthesia, essays and researches
-
Anesthetists used lower doses of fentanyl, successfully with hemodynamic control by titrating volatile anesthetic agents or vasodilators for fast-tracking in cardiac surgery. ⋯ The I-gel airway is well-tolerated by adult patients undergoing cardiac surgery, and requires lower total doses of anesthetics than endotracheal intubation with hemodynamic control and helps in fast-tracking.

For optimum magnetic resonance imaging (MRI) image quality and to ensure precise diagnosis, patients have to remain motionless. We studied the effects of intranasal dexmedetomidine and ketamine with intravenous midazolam for pre-procedural and procedural sedation in school aged children. ⋯ Intranasal dexmedetomidine 3 μg kg(-1) or ketamine 7 mg kg(-1) can be used safely and effectively to induce a state of moderate conscious sedation and to facilitate parents' separation and IV cannulation. Addition of midazolam in a dose not sufficient alone to produce the target sedation achieved our goal of deep level of sedation suitable for MRI procedure.

The favorable kinetic properties of sevoflurane could be advantageous in obese patients undergoing bariatric surgery, improving recovery from general anesthesia (GA). ⋯ Sevoflurane has a better recovery profile based on eye opening, obeying commands, time for extubation and orientation, than isoflurane in morbidly obese patients undergoing laparoscopic sleeve gastrectomy.
