Difficult face-mask ventilation and difficult laryngoscopy.
To the Editor: Our thanks are due to Kheterpal et al. 1 for another valuable addition to our understanding of airway management during anesthesia. Their work suggests that provided we exclude the patients with obvious abnormalities, we will find that the incidence of the combination of difficult mask ventilation (DMV) and difficult laryngoscopy (DL) is infrequent but not rare (0.4%), and the ou...
متن کاملMandibulohyoid distance in difficult laryngoscopy.
We studied radiographically 11 patients in whom direct laryngoscopy proved difficult and 100 control (general population) subjects. The vertical distance between the mandible and the hyoid bone (mandibulohyoid distance) was measured and the positions of the mandibular angle and hyoid bone determined in relation to the cervical vertebrae. We found that the mandibulohyoid distance was substantial...
متن کامل[Difficult laryngoscopy and tracheal intubation: observational study].
INTRODUCTION Since anesthesia complications associated with unexpected difficult airway are potentially catastrophic, they should be avoided. The modified Mallampati test and jaw-thrust maneuver enable the identification of difficult airway. The aim of this study was to associate the modified Mallampati test and the jaw-thrust maneuver with laryngoscopy (Cormack-Lehane) in an attempt to identif...
متن کاملExpected difficult tracheal intubation: a prospective comparison of direct laryngoscopy and video laryngoscopy in 200 patients.
BACKGROUND The Berci-Kaplan video laryngoscope was developed to improve the visualization of the glottis and ease tracheal intubation. Whether this technique is also effective in patients with an expected difficult intubation is unclear. We have prospectively evaluated the conditions and success rate of tracheal intubation in patients with a Mallampati score of III or IV. METHODS Two hundred ...
متن کاملIndirect laryngoscopy with rigid 70-degree laryngoscope as a predictor of difficult direct laryngoscopy.
INTRODUCTION AND OBJECTIVES The commonly-used predictors for difficult airway management are not very accurate. We investigate the power of indirect laryngoscopy with the rigid 70-degree laryngoscope as a predictor of difficult visualisation of the larynx with direct laryngoscopy. METHODS We performed preoperative indirect laryngoscopy with the rigid laryngoscope on 300 patients. The vision o...
