Morbidly obese patients are at increased risk of difficult mask ventilation and intubation as well as increased risk of hypoxemia during tracheal intubation. Recently, new video-assisted intubation devices have been developed. The GlideScope(®) videolaryngoscope and LMA CTrach™ (CT) allows continuous video-endoscopy of the tracheal intubation procedure. ⋯ The GlideScope(®) videolaryngoscope and the LMA CTrach™ reduced the difficulty, improved laryngoscopic views and overall success rate of tracheal Intubationto a similar extent compared with the Macintosh laryngoscope in morbidly obese patients. The GVL improved intubation time for tracheal intubation compared with the CT and DL but no patient became hypoxic with CT because of prolonged intubation time.

Endotracheal intubation is important to carry out various surgical procedures. The estimation of endotracheal tube size is governed by narrowest diameter of the upper airway. The objective of the study was to assess the narrowest tracheal diameter by ultrasound for selection of the appropriate size endotracheal tube. ⋯ Ultrasonography may be used for the assessment of the subglottic diameter of trachea in children to estimate the appropriate size endotracheal tube for intubation.

Dextrocardia and ventricular septal defect with situs inversus: Anesthetic implications and management.
The patients with complicated congenital heart diseases are reaching adulthood with advances in corrective surgeries and medical management. Impact of anesthetic agents on complex cardiac and extra cardiac anomalies and presence of previous palliative procedures can be a challenge for the anesthesiologist perioperatively, while these patients present for cardiac/noncardiac surgeries. We report the perioperative management of a patient with ventricular septal defect, dextrocardia, pulmonary hypertension, and situs inversus who underwent a successful hernioplasty and hydrocelectomy with a combined spinal epidural anesthesia. This discussion relates to the anesthetic management in such conditions with a special reference to Kartagener's syndrome.
