Our objective was to demonstrate that preemptive vessel dilator cricothyrotomy may be useful when managing the patient with airway obstruction. ⋯ Vessel dilator cricothyrotomy as a preemptive procedure in the management of patients with significant supraglottic airway obstruction may be a useful addition to the anesthesiologists' armamentarium of airway management devices.

Randomized Controlled Trial Comparative Study
P6 acupressure increases tolerance to nauseogenic motion stimulation in women at high risk for PONV.
In a previous study we noticed that P6 acupressure decreased postoperative nausea and vomiting (PONV) more markedly after discharge. As motion sickness susceptibility is increased by, for example, opioids we hypothesized that P6 acu-pressure decreased PONV by decreasing motion sickness susceptibility. We studied time to nausea by a laboratory motion challenge in a group of volunteers, during P6 and placebo acupressure. ⋯ In females with a history of motion sickness P6 acu-pressure increased tolerance to experimental nauseogenic stimuli, and reduced the total number of symptoms reported.

Randomized Controlled Trial
Propofol ensures a more stable A-line ARX index than thiopental during intubation.
The A-line autoregressive modelling with exogenous input index (AAI) is a new method of assessing depth of anesthesia. We examined the effects of tracheal intubation on the AAI and hemodynamics during induction of anesthesia with propofol compared with thiopental in patients aged over 50 yr. ⋯ Our results, using the AAI to monitor anesthetic depth during induction and tracheal intubation, suggest that at equipotent doses propofol provided a more stable level of anesthesia than did thiopental.

To evaluate the position of the new Microcuff pediatric tracheal tube, based upon intubation depth markings. ⋯ The intubation depth markings of the new Microcuff pediatric tracheal tube allow safe placement of the tracheal tube with a cuff-free laryngeal zone without the risk for endobronchial intubation. Placement using the intubation depth markings was superior to predicted insertion using a standard formula.
