Randomized Controlled TrialClosed-loop isoflurane administration with bispectral index in open heart surgery: randomized controlled trial with manual control.
Improved anesthetic agent delivery system (IAADS), a modification of closed-loop anesthesia delivery system (CLADS), is designed to deliver inhalational anesthetics and propofol through closed-loop control with bispectral index (BIS) as target. We compared the performance of IAADS with the manual control isoflurane administration during cardiac surgery. ⋯ The present study proves the feasibility and efficacy of inhalation anesthetic administration through closed-loop control. This is the first system that has been developed to control intravenous and inhalational anesthetic agents in a closed-loop model using BIS.

ReviewHemodynamic monitoring and outcome-a physiological appraisal.
Hemodynamic monitoring provides us with refined details about the cardiovascular system. In spite of increased availability of the monitoring process and monitoring equipment, hemodynamic monitoring has not significantly improved survival outcome. Care providers should be cognizant of the role of the cardiovascular system and its importance in oxygen delivery to the cells in order to sustain life. ⋯ Different hemodynamic monitors serve in this role to a different extent; some provide very little information on this. The cardiovascular system is only one of the many systems that need to function optimally for survival; others of equal importance include the integrity of the airway, the breathing process, the adequacy of hemoglobin level, and the health of the tissue bed, especially in the brain and the heart. Advances in hemodynamic monitoring with focus on oxygen delivery at the cellular level may ultimately provide the edge to effective monitoring that can impact outcome.

Randomized Controlled Trial Comparative StudyUse of laryngeal mask airway in children with upper respiratory tract infection, compared with face mask: randomized, single blind, clinical trial.
The incidence of postoperative cough (primary outcome) and adverse respiratory events (secondary outcome) in children who received anesthesia by laryngeal mask airway (LMA) with children who received anesthesia by face mask (FM) was compared in a blind randomized trial with uncomplicated upper respiratory track infection (URI) undergoing general anesthesia. Previous studies of pediatric patients with URI receiving anesthesia by endotracheal tube have reported a greater number of anesthetic complications; however reports concerning adverse effects in pediatric patients with URI receiving anesthesia by LMA or FM are scanty. ⋯ In children with uncomplicated URI, the administration of inhalation anesthetics in general anesthesia by LMA is likely to cause fewer adverse events than the use of FM.

Randomized Controlled TrialEqual volumes of undiluted nalbuphine and lidocaine and normal diluted saline prevents nalbuphine-induced injection pain.
To determine if the intravenous co-administration of equal volumes of lidocaine and nalbuphine, with undiluted normal saline, prevents injection pain caused by nalbuphine. ⋯ A solution of equal volumes of lidocaine and nalbuphine can decrease intravenous nalbuphine-induced injection pain.
