Anesthesia & Analgesia: December 2015 Sitsen, Elske MD et al BACKGROUND: Neuraxial blockade reduces the dose requirements of sedative agents. It is unclear whether neuraxial blockade affects the pharmacokinetics and/or the pharmacodynamics of IV hypnotics. We therefore studied the influence of epidural blockade on the pharmacokinetics of propofol in patients scheduled for general surgery. METHODS: […]

METHODS: Measurements were obtained when the attending anesthesiologist decided to perform a fluid challenge. […]

However, these measurements can be discordant when classifying AS severity. Approximately one-third of patients with normal […]
Read MoreOlder women appear to be at higher risk than older men for deterioration in neurologic and cognitive functioning as well as ventricular brain volumes following the administration of general anesthesia and surgery. That was the conclusion of a study that tracked cognitive aging in more than 500 elderly people over time. Elderly women and men […]

Video laryngoscopy (VL) improves intubation success in patients with predicted difficult airways primarily by ensuring glottic visualization. While VL with acute-angled devices has been compared […]
