Comparative Study
Estimation of desflurane concentration using isoflurane channel in optical infrared analyzer.
To estimate desflurane concentration on the isoflurane channel in an optical infrared analyzer using a simple regression equation. ⋯ The concentration of desflurane can be estimated by a simple conversion factor using an isoflurane channel of an infrared system.

To report a case of brachial plexus injury occurring on the contralateral side in a patient undergoing surgery for acoustic neuroma through translabrynthine approach. ⋯ Brachial plexus injury is still seen during anesthesia despite the awareness about its etiology. Malpositioning of the neck during prolonged surgery could lead to compression of scalene muscles and venous drainage impedance. The resultant swelling in the structures surrounding the brachial plexus may result in a severe compression.

Comparative Study
Volume kinetics of Ringer solution after surgery for hip fracture.
To study the time course of volume changes during and after infusion of Ringer's solution in elderly patients after a standardised trauma. ⋯ A slower elimination rate increased dilution of plasma and retention of fluid when Ringer's solution was infused in elderly trauma patients.

To report successful awake insertion of the intubating laryngeal mask (Fastrach) and subsequent tracheal intubation through it, in a patient with predicted difficult tracheal intubation, due to limited mouth opening, and difficult ventilation through a facemask, due to a large mass at the corner of the mouth. ⋯ Awake tracheal intubation through the intubating laryngeal mask is a useful technique in patients with limited mouth opening in whom ventilation via a facemask is expected to be difficult.
