“…Our study showed that the predictors for difficult airway management include BMI (continuous variable), cervical spine injury/fixation, history of difficult airway, head and neck mass, and oropharyngeal and/or supraglottic angioedema, which aligns with previous studies . The most interesting new finding from our study was that the otolaryngologists were able to prevent potential emergent surgical airways, as evidenced by a 71% decrease in the number of cricothyrotomies after establishment of the DART.…”

“…In another study, investigators assessed Chinese females who were pregnant and those who were not pregnant and found that the combination of predictive variables could improve the validity. [6] A study from the USA found that by using as many as ten measurements, aggregate set of variables improved predictability of a difficult intubation. [7] Iohom et al .…”

Background and Aims:Intubation is often a challenge for anaesthesiologists. Many parameters assist to predict difficult intubation. The present study was undertaken to assess the validity of different parameters in predicting difficult intubation for general anaesthesia (GA) in adults and effect of combining the parameters on the validity.Methods:The anaesthesiologist assessed oropharynx of 135 adult patients. Modified Mallampati test (MMT) was used and the thyromental distance (TMD) and sternomental distances (SMD) for each of the patients were also measured. The Cormack and Lehane laryngoscopic grading was assessed following laryngoscopy. The validity parameters such as sensitivity, specificity, false positive and negatives values, positive and negative predictive values were calculated. The effect of combining different measurements on the validity was also studied. Univariate analysis was performed using the parametric method.Results:The study group comprised of 135 patients. The sensitivity and specificity of MMT were 28.6% and 93%, respectively. The TMD (<6.5 CM) had sensitivity and specificity of 100% and 75.8%, respectively. The SMD (<12.5 CM) had sensitivity and specificity of 91% and 92.7%, respectively. Combination of MMT grading and TMD and SMD measurements increased the validity (sensitivity of 100% and specificity of 92.7%).Conclusion:MMT had high specificity. The validity of combination of MMT, SMD and TMD as compared to MMT alone was very high in predicting difficult intubation in adult patients. All parameters should be used in assessing an adult patient for surgery under GA.

“…One such challenge is difficulty with endotracheal intubation due to obesity and upper airway obstruction. In the adult population, it has been demonstrated that sleep apnea syndromes including OSA are independent risk factors for difficult endotracheal intubation [7,8]. In many patients, this relates not only to the weight or body mass index, but also correlates with the neck circumference.…”

ROHHAD syndrome is an acronym, coined in 2007, that outlines a syndrome including rapid-onset obesity, hypothalamic dysfunction, hypoventilation, and autonomic dysregulation. Common signs and symptoms include obesity, electrolyte imbalance, hypoxemia, thermal dysregulation, and gastrointestinal dysmotility. The high prevalence of neural crest tumors has led to a modification of the acronym to ROHHAD-NET when a neural crest tumor is present. Many of the findings have implications for anesthetic management. We present a 6-year-old girl with ROHHAD syndrome who presented for direct laryngoscopy, bronchoscopy, and adenotonsillectomy. Previous reports of anesthetic care for these patients are reviewed, the end-organ involvement discussed, and options for anesthetic care presented.

Use of Simple Clinical Predictors on Preoperative Diagnosis of Difﬁcult Endotracheal Intubation in Obese Patients

Abstract: The clinical and polysomnographic diagnosis of OSA proved useful in the preoperative diagnosis of difficult laryngoscopy. Obese patients are more prone to difficult facemask ventilation and laryngoscopy.
