OBJECTIVES The aim of this study was to identify correlations between sleep apnea severity and tongue volume or posterior airway space measured via three-dimensional reconstruction of volumetric computerized tomography (CT) images in patients with obstructive sleep apnea (OSA) for use in predicting OSA severity and in surgical treatment. We also assessed associations between tongue volume and M...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014207084 DESCRIPTION A 30-year-old woman with fibroid uterus was operated on for myomectomy under general anaesthesia. Preoperative evaluation revealed adequate mouth opening, neck extension, thyromental distance and Mallampati grade 1. In the operating room, anaesthesia was...

OBJECTIVES/HYPOTHESIS To identify standard clinical parameters that may predict the optimal level of continuous positive airway pressure (CPAP) in adult patients with obstructive sleep apnea/hypopnea syndrome (OSAHS). STUDY DESIGN This is a retrospective study in a tertiary academic medical center that included 129 adult patients (117 males and 12 females) with OSAHS confirmed by diagnostic p...

BACKGROUND Previous studies have failed to detect high body mass index (BMI) as a risk factor for difficult tracheal intubation (DTI). BMI was investigated as a risk factor for DTI in patients planned for direct laryngoscopy. METHODS A cohort of 91,332 consecutive patients planned for intubation by direct laryngoscopy was retrieved from the Danish Anesthesia Database. A four-point scale to gr...

A 23-year-old male patient with occipitocervical fixator was scheduled for surgery due to injury to the right forearm. The patient's thyromental distance was 5 cm, mouth opening grade II, sternomental distance 10 cm and Mallampati score 4. Loss of extension and rotation movements of the head was assessed as difficult intubation criteria. Anaesthetic procedures are almost always difficult in pat...

Emergency and difficult tracheal intubations are hazardous undertakings where successive laryngoscopy-hypoxaemia-re-oxygenation cycles can escalate to airway loss and the 'can't intubate, can't ventilate' scenario. Between 2013 and 2014, we extended the apnoea times of 25 patients with difficult airways who were undergoing general anaesthesia for hypopharyngeal or laryngotracheal surgery. This ...

Difficult intubation can be found in 11% of emergency tracheal intubations.1 Predictors of difficult tracheal intubation have been described, such as mouth opening, Mallampati classification, atlanto-occipital joint extension, mandibulohyoid distance, inter-incisor distance, thyromental distance, sternomental distance, obesity, and a previous history of difficult intubation.2 The occurrence of ...

Abstract Background Sternomental displacement (SMDD) is a surrogate indicator for cervical spine (C-spine) mobility. SMDD revealed good potential to predict difficult airway, but its validity in obese patients not evident. Therefore, this study assessed the performance of with neck circumference (NC) predicting airway surgical patients. The involved 135 adult body mass index (BMI) ≥ 35 kg/m 2 s...
