[Comparison of hemodynamic responses to orotracheal intubation with shikani laryngoscope or macintosh direct laryngoscope].

Objective: To compare the hemodynamic responses to orotracheal intubation using a Shikani Optical Stylet (SOS) laryngoscope or a Macintosh direct laryngoscope (MDLS).

Methods: Totally 41 patients with American Society of Anesthesiologists ASA physical status -aged 20-60 years and scheduled for elective surgery under general anesthesia requiring orotracheal intubation, were randomly allocated to either the SOS group (n=21) or MDLS group (n=20). After an intravenous anesthetic induction the orotracheal intubation was performed using a SOS laryngoscope or a MDLS.

[Analysis of anesthetic methods for tracheal resection and reconstruction with artificial trachea: a report of 25 cases].

Objective: To analyze and discuss the anesthetic methods and processes for the operations including long-segment resection of the trachea and one-stage anastomosis or reconstruction with artificial trachea.

Methods: The clinical data of 25 cases from January 1987 to August 2007 with trachea diseases were analyzed retrospectively. There were 10 cases with benign diseases and 15 cases with malignant diseases.

[Detection of esophageal intubation-assessment of several methods in clinical anesthesia].

Objective: To evaluate the sensitivity and reliability of several widely used tests for prompt detection of inadvertent esophageal intubation.

Methods: Both endotracheal and esophageal intubations were made on 40 adult patients undergoing general anesthesia. The tests such as auscultation of bilateral apex of lungs and epigastrium by inexperienced examiners, capnography, SpO2, chest and upper abdomen movements, and airway resistance were evaluated.
