Laryngoscopy and intubation increases blood pressure and heart rate. The study aims to investigate the effect and safety of gabapentin, clonidine or esmolol on the haemodynamic response to laryngoscopy and intubation. Fiftysix ASA I and II patients undergoing elective surgery were randomly allocated to one of the four groups. First study drug was administered orally as gabapentin 1200mg or clon...

UNLABELLED BACKGROUND The purpose of our study was to organize the literature regarding the efficacy of modern videolaryngoscopes in oral endotracheal intubation, then perform a quality assessment according to recommended external criteria and make recommendations for use. METHODS Inclusion criteria included devices with recent studies of human subjects. A total of 980 articles were return...

BACKGROUND Preoperative evaluation of anatomical landmarks and clinical factors are important in the detection of patients at risk for difficult laryngoscopy. The modified Mallampati test (MMT) and thyromental distance (TMD) are commonly used for this purpose but there are controversies regarding their accuracy. OBJECTIVE The objective of the present study was to evaluate the accuracy of MMT ...

Morbid obesity is associated with difficult laryngoscopy and intubation. In the general population, bedside indices for predicting difficult intubation (i.e. Mallampati classification, thyromental distance, sternomental distance, mouth-opening and Wilson risk score) have poor-to-moderate sensitivity (20-62%) and moderate-to-fair specificity (82-97%). In the obese population, although the risk o...

OBJECTIVES Video laryngoscopy has been shown to improve glottic exposure when compared to direct laryngoscopy in operating room studies. However, its utility in the hands of emergency physicians (EPs) remains undefined. A simulated difficult airway was used to determine if intubation by EPs using a video Macintosh system resulted in an improved glottic view, was easier, was faster, or was more ...

BACKGROUND Despite the established vulnerability of children during airway management, remarkably little is known about complications in children with difficult tracheal intubation. To address this concern, we developed a multicentre registry (Pediatric Difficult Intubation [PeDI]) to characterise risk factors for difficult tracheal intubation, establish the success rates of various tracheal in...

Introduction During suspension laryngoscopy, dexmedetomidine’s lack of respiratory depression can be helpful in simulating laryngeal changes present during spontaneous ventilation. Despite these beneficial effects, dexmedetomidine has additional effects on the cardiovascular system. The aim of this abstract is to present a case of acute asystole during suspension laryngoscopy using dexmedetomid...

OBJECTIVE Laryngoscopy and tracheal intubation may cause significant cerebral and systemic hemodynamic responses. Many drugs have been shown to be effective in modifying these hemodynamic responses, including fentanyl, sufentanil, alfentanil and remifentanil. The purpose of the current study was to compare the efficacy of fentanyl, sufentanil, alfentanil and remifentanil on blunting cardiovascu...

conclusions the tmd, with a cut-off point of 65 mm, had superior diagnostic value compared with the hmdr and mallampati score. therefore, the tmd could be used in malay patients to predict the difficulty of larynx visualization during laryngoscopy. results difficulty in visualizing the larynx was found in 28 (10.1%) patients. the auc, sensitivity, and specificity for the three airway predictors...
