Laryngospasm is reversible spasm of vocal cords that common in patients who are undergoing upper airway related surgeries under general anaesthesia. It occurs mostly following extubation; requires immediate management and if these left untreated rapid decrease saturation with bradycardia may take place. Lignocaine considered effective prevention laryngospasm by both topical intravenous route. a...

Next day the condition became very acute resembling static asthma without the typical adventitious sounds. The voice was very husky but loud enough to be audible. Inspiration was very difficult and expiration was slightly less so. Indirect laryngoscopy (after desensitization of the pharynx): Both the vocal cords were congested and drawn together, almost touching each other and in the middle lin...

The cuff-leak test was widely used for the prediction of post-extubation stridor, but controversial results limit its clinical application. The current study used real-time ultrasonography to evaluate the air-leak and hypothesised that the air-column width, measured by ultrasonography, may be correlated to the development of post-extubation stridor. From June 1, 2001 to March 1, 2002, a total o...

INTRODUCTION Several studies show that early histological classification and excision of precancerous lesions of the vocal cords reduces the risk of cancer development. National Danish guidelines have not been established. The purpose of this study was to describe a Danish series of patients with precancerous lesions of the vocal cords and to estimate the risk of malignant transformation. MAT...

We wish to thank Dr. Wilson for suggesting that the bilateral vocal cord paralysis we reported in a patient with Guillain Barre syndrome may have resulted from trauma secondary to intubation with a cuffinflated endotracheal tube. Although this explanation could have contributed to the paralysis, we believe it was primarily the result of the Guillain Barr6 syndrome because: 1. Prior to intubatio...

Abstract This paper presents a proposal to source-filter theory of voice production, more precisely related voiced sounds. It is model generate signal using linear and time-invariant systems takes into account the phonation biophysics cyclostationary characteristics signal, vibrational behavior vocal cords. The suggests that oscillation frequency cords function its mass length, but controlled b...
