P.V.C. CUFFS AND LIGNOCAINE-BASE AEROSOL

Plasma lignocaine concentrations following endotracheal spraying with an aerosol.

Plasma concentrations of lignocaine were measured in three groups of anaesthetized patients following spraying of the trachea and larynx with a lignocaine 10% aerosol spray. Greater venous plasma concentrations occurred in patients who were paralysed with suxamethonium. A mean plasma concentration of 0.1 mug/ml of lignocaine resulted from each 10 mg of lignocaine used in spontaneously breathing...

Interrupting gel layer between Double cuffs prevents fluid leakage past tracheal tube cuffs.

BACKGROUND Current tracheal tubes (TTs) cannot guarantee a perfect seal against pulmonary aspiration of upper airway secretions. The purpose of this study was to investigate whether a gel layer between the tracheal tube with double cuffs (Double cuffs) prevents fluid leakage past TT cuffs. METHODS In vitro fluid leakage tests were performed using the Double cuff with or without a gel layer be...

Experimental PVC Material Challenge in Subjects with Occupational PVC Exposure

BACKGROUND Polyvinyl chloride (PVC) materials have been linked to asthma in several epidemiologic studies, but the possible causal factors remain unknown. PARTICIPANTS We challenged 10 subjects experimentally to degraded PVC products under controlled conditions. All of the subjects had previously experienced respiratory symptoms suspected to be caused by this kind of exposure in their work pl...
