“…Some studies indicate BMI ≥ 35 kg/m 2 as a weak predictor of difficult intubation . One study suggests that difficult intubation in obese patients could be caused by suboptimal positioning and, further to this, another study argues that BMI > 35 kg/m 2 does not per se predict difficult laryngoscopy following optimal positioning …”

“…Out of 70 patients, difficult intubation was observed in 23(32.86%) patients whereas 47 (67.14%) patients were observed with normal intubation. found in their study that difficult intubation was related to high Body Mass Index (BMI) , increasing neck circumference, short thyromental distance, and the Mallampati score of > or = 3 and stated that Neck circumference was an self-sufficient warning feature to predict difficulty in intubation in overweight subjects [3,10].…”

Background and Objectives:Patient identification with difficult intubation is important in planning anesthetic management and one major factor for difficult intubation in the obese patients is large neck circumference. The need for prediction of a potentially difficult airway received great importance as it plays a significant role in reducing morbidity and mortality. Therefore, this study was done to glimpse the effect of neck circumference on endotracheal intubation and to determine the frequency of difficult intubation. Material and Methods:The study was cross sectional descriptive study and convenient sampling technique was used. Seventy patients of age between 19-50 years of both sexes were enrolled. Neck circumference was measured at the level of cricoid cartilage along with other airway assessments. Direct laryngoscopy was done and checked whether it is difficult one or easy using Intubation difficulty scale. Data were entered and analyzed by using statistical software SPSS version 15.0. Results:Mean BMI was noted as 33.02±2.30 kg/m2 and the mean neck circumference was 43.64±2.30 cm. Difficult intubation was observed in 23 (32.86%) patients with mean neck circumference of 45.44±1.88 cm and normal intubation observed in 47(67.14%) patients with mean neck circumference of 42.77±1.98 cm. Linear correlation was found between the neck circumference and Intubation Difficulty Scale score with value of Pearson correlation=0.617. Conclusion:Neck circumference of patient was found to have significant effects on difficult intubation. Frequency of difficult intubation was found in almost one third of obese patients with increasing neck circumference.

“…Although, difficult intubation rate is higher in obese than in lean patients [12,13], some cohorts advocate that this issue is still controversial, since evidences of this phenomenon are not clear [14]. In patients with morbid obesity standard predictors of difficult intubation are not satisfactory.…”

Abstract:Telemedicine is defined as the delivery of health care and the share of medical knowledge over distance using telecommunications systems. One of the main purposes of telemedicine is to improve accessibility to specialty consultation in remote areas and to reduce the costs of traditional health practices. Telemedicine is used in preoperative assessment and in anesthesia with positive perceptions by patients. Furthermore the possibility to realize transcontinental anesthesia, represents the pathway through which geographical barriers will be no longer limiting factors in high quality health care delivery.
