Multicenter Study Comparative Study Clinical Trial Controlled Clinical Trial
A field comparison of the pharyngeotracheal lumen airway and the endotracheal tube.
A prospective, sequential study compared ease of use and bag-valve ventilation delivered by an endotracheal tube (ET) with that of the pharyngeotracheal lumen airway (PtL) for 111 victims of cardiac arrest in the pre-hospital setting. The PtL airway was found to be significantly easier to use as measured by the time required to intubate the patient and the number of attempts to place the device. Arterial blood gas determinations were made on arrival at the hospital and repeated 15 minutes later. ⋯ No adverse effects were reported. We conclude that the ability of the PtL to deliver effective ventilation is comparable with that of the ET as measured by arterial PCO2. When the ET method of airway control cannot be achieved, the PtL airway offers an effective alternative.

Endoesophageal prostheses are sometimes used in palliative therapy of esophageal carcinoma. Placement or subsequent manipulation of these devices may require general anesthesia, and these anesthetics are fraught with potential complications, both from the patient's illness and from the prosthesis itself. The two patients in our report presented anesthetic challenges, including acute upper airway obstruction occurring outside the operating theater and management of malignant tracheoesophageal fistula.

Comparative Study Clinical Trial Controlled Clinical Trial[Pressure changes in the pneumoballoon of several endotracheal tubes after the administration of nitrous oxide].
We compare the degree of nitrous oxide diffusion in three types of endotracheal tubes available in the market, by means of continuous monitoring of the pressure attained at the pneumoballoon. Among the systems designed to impede or to minimize nitrous oxide diffusion, we have used in this study the so called "rediffusion system". ⋯ We believe that during anesthesia with nitrous oxide the pneumoballoon pressure should be monitored or systems that avoid diffusion of this inhalational agent should be inserted. Our results indicate that endotracheal tubes equiped with "rediffusion system" are effective in impeding diffusion of the inhalational agents.
