Randomized Controlled Trial Comparative Study
Comparison of hemodynamic responses to orotracheal intubation with the GlideScope videolaryngoscope and the Macintosh direct laryngoscope.
To identify the hemodynamic responses to orotracheal intubation using a GlideScope videolaryngoscope (GSVL) in healthy adults, and to determine whether the GSVL could attenuate the hemodynamic response to orotracheal intubation compared with the Macintosh direct laryngoscope (MDLS). ⋯ The hemodynamic responses to orotracheal intubation using a GSVL and an MDLS were similar. The GSVL had no any special advantage over the MDLS in attenuating the hemodynamic responses to orotracheal intubation.

To determine--through reconstruction of a clinical situation in which a syringe filled with insulin was removed from the syringe pump, placed above the patient, then emptied into the patient--the different physical forces at work, and to examine the height of the syringe (and thus the hydrostatic force) necessary to move the plunger. ⋯ Studies testing the effect of siphoning using one syringe cannot be interpreted reliably. Smaller syringes are safer to avoid siphoning.

The prone position impairs the ability for endotracheal intubation by direct laryngoscopy. We describe the airway management of a 25-year-old woman with an extensive open wound over her back and fractured pelvis. She was treated in the prone position and was scheduled for debridement of her wound with skin grafting during general anesthesia. Her trachea was successfully intubated on the first attempt using an intubating Laryngeal Mask Airway while she was in the prone position.

Ipsilateral shoulder pain after thoracic surgery is a distressing problem and is associated with impairment of respiratory and shoulder function. The most suggested etiology for this shoulder pain is referred phrenic nerve pain. However, we have made clinical observations that suggest shoulder ligament strain as another cause of the shoulder pain.
