Bronchoscopic Intubation and Light Guided Bronchoscopic Intubation:Success Rate and Time in Untrained Medical Personnel

2014-07-24 14:01:14 | BioPortfolio


Bronchoscopic intubation is the preferred technique to difficult airway. However, when performed by untrained anesthesiologists, bronchoscopic intubation has a high rate of failure. We want to know if the Light Guided Bronchoscopic intubation technique can improves the success rate and time for tracheal intubation performed by inexperienced anesthesiologists; whether this technique improves the success rate and for normal intubations when performed by inexperienced anesthesiologists as well is unknown. Therefore, the authors compared the success rate and time of bronchoscopic intubation versus the Light Guided Bronchoscopic intubation performed by anesthesiologists inexperienced in Bronchoscopic intubation.


After approval by the ethics committee of the Changhai hospital, Shanghai, China, 22 subjects and 220 patients gave their informed written consent to participate in this study. All the subjects had not yet intubated a patient with Bronchoscopy.

Patients were included who were older than 18 yr, had to undergo elective surgery under general anesthesia with tracheal intubation, and were classified as American Society of Anesthesiologists physical Status I or II. The patients had a Mallampati score of I or II, at least 3 cm of mouth opening. The patients were enrolled into the study and gave their consent at the preoperative evaluation center to anesthesiologists who were not informed of the status of the alternating sequence of the 2 techniques. These anesthesiologists set a fixed order of patients. The subjects and their attending anesthesiologist in the operating room had no influence on or choice of which patient would be next on their alternating list; i.e., they received a fixed order of patients and had no influence on which patient had to be intubated with which technique. This way, we are convinced that on one hand the alternating sequence guarantees that no randomized order can influence the learning curve with each technique, and on the other hand that the subjects had no influence on the choice of technique for a specific patient, although the sequence of patients was not formally randomized.

Medical and Biotech [MESH] Definitions

Analytical technique for studying substances present at enzyme concentrations in single cells, in situ, by measuring light absorption. Light from a tungsten strip lamp or xenon arc dispersed by a grating monochromator illuminates the optical system of a microscope. The absorbance of light is measured (in nanometers) by comparing the difference between the image of the sample and a reference image.

Treatment using irradiation with light of low power intensity so that the effects are a response to the light and not due to heat. A variety of light sources, especially low-power lasers are used.

The adjustment of the eye to variations in the intensity of light. Light adaptation is the adjustment of the eye when the light threshold is increased; DARK ADAPTATION when the light is greatly reduced. (From Cline et al., Dictionary of Visual Science, 4th ed)

A light microscopic technique in which only a small spot is illuminated and observed at a time. An image is constructed through point-by-point scanning of the field in this manner. Light sources may be conventional or laser, and fluorescence or transmitted observations are possible.

An enzyme that phosphorylates myosin light chains in the presence of ATP to yield myosin-light chain phosphate and ADP, and requires calcium and CALMODULIN. The 20-kDa light chain is phosphorylated more rapidly than any other acceptor, but light chains from other myosins and myosin itself can act as acceptors. The enzyme plays a central role in the regulation of smooth muscle contraction.
