Validity of bispectral index monitoring during deep sedation in children with spastic cerebral palsy undergoing injection of botulinum toxin.
Authors: Jung SM, Lee E, Park SJ Abstract Background: This prospective study aimed to determine whether the bispectral index (BIS) is a valid objective tool for differentiating adequate from inadequate deep sedation in spontaneously breathing children with cerebral palsy (CP). Methods: Propofol was titrated to increase the level of sedation with a continuous infusion of remifentanil at a rate of 0.05 μg/kg/min while maintaining spontaneous ventilation in 22 children with spastic CP, aged 3-18 years. The depth of sedation was assessed using the University of Michigan Sedation Scale (UMSS) and the Modified Obs...

Assessment of phase-lag entropy, a new measure of electroencephalographic signals, for propofol-induced sedation.
This study was performed to evaluate the performance of PLE for assessing the depth of sedation. METHODS: Thirty adult patients undergoing upper limb surgery with a brachial plexus block were administered propofol by target-controlled infusion. The depth of sedation was assessed using the Observer's Assessment of Alertness/Sedation (OAA/S) scale. The effect-site concentration (Ce) of propofol was initially started at 0.5 μg/ml and was increased in increments of 0.2 μg/ml until an OAA/S score of 1 was reached. Three minutes after the target Ce was reached, the PLE, bispectral index (BIS), and level of sedation wer...

Multicollinearity and misleading statistical results.
Authors: Kim JH Abstract Multicollinearity represents a high degree of linear intercorrelation between explanatory variables (EVs) in a multiple regression model. Because of its presence, the results of regression analysis go wrong. The diagnostic tools of multicollinearity include variance inflation factor (VIF), condition index (CI) and condition number (CN), and variance decomposition proportion (VDP). Multicollinearity can be presented by the coefficient of determination (Rh2) for a multiple regression model with one EV (Xh) as the model's response variable and the others (Xi[i≠h]) as its EVs. The variances ...

This article summarizes what is currently known about the relevant pathophysiology of concussion, intraoperative anesthesia considerations, and effects of anesthesia on concussion outcomes in an attempt to help providers understand the risks that may accompany surgery and anesthesia in this patient population. While most contraindications to the use of anesthesia in concussed patients are relative, there are nonetheless pathophysiologic changes associated with a concussion that can increase risk of its use. Understanding these changes and anesthetic implications can help providers optimize outcomes in this patient populati...

Dexmedetomidine: present and future directions.
Authors: Lee S Abstract Dexmedetomidine is a potent, highly selective α-2 adrenoceptor agonist, with sedative, analgesic, anxiolytic, sympatholytic, and opioid-sparing properties. Dexmedetomidine induces a unique sedative response which shows easy transition from sleep to wakefulness, allowing a patient to be cooperative and communicative when stimulated. Dexmedetomidine may produce less delirium compared with other sedatives, or even prevent delirium. Analgesic effect of dexmedetomidine is not strong, however, it can be administered as a useful analgesic adjuvant. Dexmedetomidine decreases the need for opioi...

High-flow nasal oxygenation for anesthetic management.
Authors: Asai T, Kim HJ Abstract High-flow nasal oxygenation (HFNO) is a promising new technique for anesthesiologists. The introduction of HFNO during induction of anesthesia and during upper airway surgery has been initiated and its applications have been rapidly growing. The advantages include its easy setting, high tolerability, its ability to produce positive airway pressure, a high fraction of inspired oxygen (FiO2) and some clearance of carbon dioxide. HFNO via nasal cannula can provide oxygen, both in patients breathing spontaneously and in those being apnea, and does not interfere with bag-mask ventilation...
