Clinical TrialBeneficial effects of intranasal applications of capsaicin in patients with vasomotor rhinitis.
Capsaicin, a nonenamide derived from Capsicum plants, has proven useful in patients with vasomotor rhinitis. In the present study, we studied the effects of 15 micrograms capsaicin suspended in 100 microliters solution in patients with known vasomotor rhinitis. Drug was given 3 times/day for 3 days to each patient by means of a spray delivered to the nasal mucosa. ⋯ The mean symptom score involving nasal obstruction and nasal secretion was markedly reduced by capsaicin treatment. We advance the hypothesis that the beneficial effect of drug treatment may be due to its specific action on the peripheral endings of primary sensory neurons leading to their functional blockade. Further randomized, double-blind, placebo-controlled trial is now needed.

Microsurgical endoscopic interventions of the larynx offer an optimal approach to the surgeon by providing an unrestricted operative field. During such operations, ventilating the patient should in no way be impaired. For this reason we have developed a new type of tubeless jet ventilation which consists of both low-frequency and superimposed high-frequency jet ventilation. ⋯ Clinical results revealed optimal ventilation of all patients without hypercapnia or other complications. Operative conditions for the surgeon were also very satisfactory. Findings demonstrated that this type of tubeless jet ventilation is also particularly suited for laryngeal laser surgery, thus avoiding flammable tubes and noxious anesthetics.

Case ReportsEmergency ventilation using the Combitube in cases of difficult intubation.
The esophageal-tracheal Combitube (Sheridan, Argyle, NY) is a new device for emergency intubation, which can be inserted blindly without the use of a laryngoscope. Ventilation is independent of the position of the Combitube in either the esophagus or the trachea, since ventilation is always provided by the tube's double channel. The "tracheal" channel acts as a conventional endotracheal airway and has an open distal end. ⋯ Endotracheal intubation failed because the glottis could not be visualized with a laryngoscope. In both cases the Combitube was applied successfully and adequate ventilation was provided via the Combitube placed esophageally. To better secure each patient's airway, tracheotomy was performed during ventilation without any complications.
