This is a report of a modification of the standard Macintosh laryngoscope blade to facilitate tracheal tube placement in cases of difficult visualisation of the larynx. The modification offers the unique advantage of a hinged blade tip, controlled by a lever on the handle of the laryngoscope which allows elevation of the epiglottis while decreasing the(More)
In characterising the forces exerted during laryngoscopy it is accepted that the significant force component is that which is parallel to the axis of the laryngoscope handle. This paper describes a new method of evaluating the forces exerted at laryngoscopy. A laryngoscope handle has been redesigned, incorporating a force-displacement transducer on the(More)
The TOF-Guard neuromuscular monitor uses an accelerometer to measure the response to nerve stimulation. In this study, we have compared it to a standard mechanomyographic monitor, the Myograph 2000, for neuromuscular monitoring in 28 subjects. A train-of-four mode of stimulation was used in both cases. The times taken for onset of block, and for the(More)
The forces exerted at laryngoscopy with the McCoy and Macintosh blades have been compared in 40 patients. The variables measured were the duration of laryngoscopy, the three maximally-applied forces and the mean force. The mean (SD) forces recorded were 18.9 (7.82) and 10.1 (5.33) N, respectively, with the Macintosh and the McCoy blades (p < 0.001) with a(More)
The dose-response relationship for edrophonium during antagonism of vecuronium-induced neuromuscular blockade was studied in two groups of adult patients of mean (SD) age 35 (10.0) years (n = 42) and 77 (5.4) years (n = 42) respectively. Neuromuscular block was monitored by recording the force of contraction of the adductor pollicis muscle following(More)
The aim of this study was to examine differences in prejunctional effects of different relaxants by measuring the train-of-four (TOF) fade during the onset and recovery of neuromuscular block. The relaxants studied were atracurium (225 micrograms.kg-1), mivacurium (65 micrograms.kg-1) rocuronium (300 micrograms.kg-1) and vecuronium (40 micrograms.kg-1). The(More)
Malignant hyperthermia is a pharmacogenic disease and is manifest by a hypermetabolic crisis with tachycardia, ventricular ectopy, metabolic acidosis, and a rapid rise in body temperature. "Ecstasy", 3,4-methylenedioxy-methamphetamine (MDMA), is a semisynthetic amphetamine, the recreational use of which has increased in recent years. Severe reactions to(More)
