ABSTRACTPurpose: To compare the amount of esotropia corrected by surgery under general anesthesia and in a conscious state in esotropia surgery. Methods: The charts of 42 patients who underwent surgery under general anesthesia for correction of esotropia were reviewed. Angle of deviation was measured by the alternate prism cover test in awakened state one day before and after surgery. Under general anesthesia, angle of deviation was measured by Hirschberg or Krimsky test in 5 prism diopters (PD)...
Abstract Background The bispectral index parameter is used to guide the titration of general anesthesia; however, many studies have shown conflicting results regarding the benefits of bispectral index monitoring. The objective of this systematic review with meta-analysis is to evaluate the clinical impact of monitoring with the bispectral index parameter. Methods The search for evidence in scientific information sources was conducted during December 2013 to January 2015, the following primary da...
Background Bispectral index (BIS ) monitoring has been used as an objective measurement tool for sedation depth and has been proposed as a guidance to reduce the risk of intraprocedural over-sedation. However, the results of several studies evaluating the benefits of BIS monitoring for gastrointestinal endoscopy were not consistent.
BACKGROUND: Moderate sedation is routinely performed in patients undergoing minor therapeutic and diagnostic procedures outside the operating room. The level of sedation is often monitored by sedation nurses using clinical criteria, such as sedation scores. The Bispectral Index (BIS) is derived from changes in the electroencephalograph profile that may provide an objective measure of the level of sedation. In this prospective observational study, we investigated whether using BIS values to guide...
Background The use of clinical signs may not be reliable in measuring the hypnotic component of anaesthesia. The use of bispectral index (BIS) to guide the dose of anaesthetic may have certain advantages over clinical signs. This is the second update of a review originally published in 2007 and updated in 2014. Objectives The primary objective of this review focused on whether the incorporation of BIS into the standard practice for management of anaesthesia can reduce the risk of intraoperative ...
BACKGROUND: It is important that the level of general anaesthesia (GA) is appropriate for the individual patient undergoing surgery. If anaesthesia is deeper than required to keep a patient unconscious, there might be increased risk of anaesthetic-related morbidity, such as postoperative nausea, vomiting and cognitive dysfunction. This may also prolong recovery times, potentially increasing health-care costs. If anaesthesia is too light, patients may not be fully unconscious and could be at risk...
PURPOSE: The authors attempted to identify the determinants of ocular deviation in a population of patients with esotropia under general anesthesia. METHODS: Forty-one patients with esotropia were included. Horizontal ocular deviation was evaluated by the photographic Hirschberg test both in the awakened state and under general anesthesia before surgery. Changes in ocular deviation were measured and a multivariate analysis was used to assess its clinical determinants. RESULTS: The mean age (± st...
PURPOSE: To determine whether changes in ocular alignment following general anesthesia, as measured by interpupillary distance, can be used as a predictor for surgical outcomes in children with intermittent exotropia. METHODS: The authors obtained digital photographs of 40 children with exotropia and 20 children with epiblepharon (control group) before and immediately after induction of general anesthesia in the primary supine position. Differences in the anatomic interpupillary distance (aIPD) ...
