Dynamic Interaction of Craniofacial Structures during Head Positioning and Direct Laryngoscopy in Anesthetized Patients with and without Difficult Laryngoscopy

Expected 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 ...

Previsional space during direct laryngoscopy: Implication in the difficult laryngoscopy: Erratum

Head and neck position for direct laryngoscopy.

The sniffing position (SP) has traditionally been considered the optimal head position for direct laryngoscopy (DL). Its superiority over other head positions, however, has been questioned during the last decade. We reviewed the scarce literature on the subject to examine the evidence either in favor or against the routine use of the SP. A standard definition for the position should be used (e....

Indirect 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...

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...
