PURPOSE: Mask ventilation and laryngoscopy can be challenging in morbidly obese patients because of excessive fat tissue. There are studies suggesting that neck circumference is associated with difficult mask ventilation, difficult laryngoscopy, and difficult intubation. The primary aim of our study is to evaluate predictive value of neck circumference for difficult mask ventilation and difficult laryngoscopy in female and male morbidly obese patients separately. METHODS: This observational cross-sectional study was performed in the period between March 2015 and December 2015...

Endotracheal tube (ETT) management is an essential technique in handling mice with mechanical ventilators. Malposition into bronchi causes not only lethal complications for them but also less efficient mechanical ventilation. However, in general, it is difficult to know whether the ETT is placed with appropriate depth into the trachea of mice. We measured the distance from incisors to the bifurcation of trachea of multiple mice, and created a new estimation formula to obtain the suitable ETT length for mice with a body weight range from 17 g to 25 g: length (mm) = 0...

The C-MAC videolaryngoscope was evaluated for intubation in patients with predicted extremely difficult airway. The presented cases are patients with neoplasm tumors in larynx. In all cases, awake intubation using C-MAC videolaryngoscope was performed in patients breathing spontaneously, under local anaesthesia, with oxygen administered via nasal catheter. All intubations were successful and uneventful. The pre-surgery examination (CT scans and fiberscope laryngeal examination) was compared with view of larynx obtained during laryngoscopy...

Introduction: An acquired Tracheoesophageal fistula (TEF) is commonly caused by a malignancy or trauma, with pulmonary infection or aspiration being the presenting symptom. However, in the critical care setting the presentation can be subtle and may present with difficult ventilation. High endotracheal tube cuff pressures can lead to tracheal erosions and thus increasing the chances for developing a TEF. Prolonged intubation in the presence of other risk factors like poor general state of health, episodic hypotension, nasogastric tubes, and repeated intubations can increase the likelihood of developing an acquired TEF...

Background: The difficult intubation is associated with failure of emergency tracheal intubation. This study aimed to develop and validate a model for predicting difficult intubation in emergency department (ED). Methods: A cross-sectional study was conducted in the ED. We collected data from all consecutive adult patients who underwent emergency tracheal intubation. Patients were excluded if they were intubated by low experience intubator. The difficult intubation was defined by grade III or IV of Cormack and Lehane classification...

Background: Direct laryngoscopy is the gold standard of the airway management in patients without predicted difficulties. If unpredicted difficulties are encountered instead, different algorithms to follow have been developed. To date, no single predictor is sufficiently valid. In clinical practice, it is used a combination of them to enhance the estimate, and despite the variety of parameters used, not all the difficult intubations are predicted. The aim of this work is to retrospectively analyze neck computed tomography scans of 37 patients who have had tracheal intubation and search for anatomic neck fat compartments that correlate with the intubation difficulty, and eventually find a suitable, clinical parameter that can potentially enhance the prediction of a difficult airway when used in combination of the preexisting scores...

BACKGROUND: The 2009 World Health Organisation (WHO) surgical safety checklist significantly reduces surgical mortality and morbidity (up to 47%). Yet in 2016, only 25% of East African anesthetists regularly use the checklist. Nationwide implementation of the checklist is reported in high-income countries, but in low- and middle-income countries (LMICs) reports of successful implementations are sparse, limited to single institutions and require intensive support. Since checklist use leads to the biggest improvements in outcomes in LMICs, methods of wide-scale implementation are needed...

Predicting and managing the difficult airway is a lifesaving and vital basic task for the anesthetist. Current guidelines of all important societies include thyromental distance (TMD, "Patil") as a possible predictor for a difficult airway and includes two important aspects for airway management: the mandibular space and the flexibility of the cervical spine. We evaluated knowledge and execution regarding TMD for predicting a difficult airway on participants at the Euroanaesthesia (ESA) congress and German Anaesthesia Congress (DAC) in 2014...
