Forces acting on the maxillary incisor teeth during laryngoscopy using the Macintosh laryngoscope.
We determined the forces on the maxillary incisors during routine laryngoscopy in 65 adult patients. The forces were measured by a strain gauge based sensor positioned between the handle and the blade of the laryngoscope. The mean maximal force acting on the maxillary incisors was 49 N. In patients without maxillary incisors, the force acting on the gums was significantly lower at 21 N (p < 0.0...
متن کاملDoes experience influence the forces exerted on maxillary incisors during laryngoscopy? A manikin study using the Macintosh laryngoscope.
The influence of the level of experience of the laryngoscopist on the duration of laryngoscopy, the forces exerted on the tongue and on the maxillary incisors during laryngoscopy, were investigated. Five groups (anaesthetists, residents in anaesthesia, nurse anaesthetists, surgeons and medical students), each consisting of 15 individuals, participated in the study. An intubation manikin was use...
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...
متن کاملThe McGrath Series 5 video laryngoscope versus the Macintosh laryngoscope: a randomized trial in obstetric patients.
BACKGROUND/AIM Anesthesiologists have encountered various difficulties in securing the airway. Therefore, we compare the intubation times and hemodynamic changes between the McGrath Series 5 video laryngoscope and the Macintosh laryngoscope. MATERIALS AND METHODS A total of 80 obstetric patients were divided into 2 groups, orotracheally intubated with either the McGrath video laryngoscope or ...
متن کاملGlidescope® video laryngoscope vs. Macintosh direct laryngoscope for the intubation of laryngeal neoplasm patients: a randomized controlled study
Background: Glidescope® video laryngoscope (GVL) is widely used in tracheal intubation. However, no studies have been conducted to compare the GVL and Macintosh direct laryngoscope (MDL) for intubation in patients with laryngeal neoplasm. Here, we aim to compare GVL and MDL for the intubation of laryngeal neoplasm patients. Methods: One hundred ninety-six American Society of Anesthesiology (ASA...
