We modified the technique for laryngeal mask airway (LMA) insertion in children. This modification involves inserting a two-thirds inflated LMA with its lumen facing laterally toward left and then rotating it 90 degrees clockwise as it passes downwards into position behind the larynx. Then the cuff is inflated fully. ⋯ There were no significant differences in vital signs between pre- and post-insertion. Only one child was found to have attachment of blood clots on the surface of the removed LMA. We conclude that our technique would be one recommended method in pediatric practice.

We report anesthetic experience of two patients suffering from polymyositis. The first case is a 56 year old woman who underwent tympanoplasty for cholesteatoma of the middle ear. Anesthesia was induced with thiopental and deepened with oxygen-nitrous oxide and sevoflurane. ⋯ Concerning the anesthetic management of a patient with polymyositis, there are some informations on the appropriate use of muscle relaxants. It is generally believed that the patient is sensitive to nondepolarizing muscle relaxants and the use of antagonist drug (reversal) may cause muscle weakness, severe dysrhythmia, et al. Therefore we think it is appropriate to manage such a patient without muscle relaxants.

The hemodynamic and pulmonary effects of fluid resuscitation with crystalloid and colloid solutions in the presence of mild pulmonary edema were investigated. Anesthetized dogs received oleic acid to increase pulmonary capillary permeability, and one hour later bled to produce hemorrhagic shock. One hour after the shock, resuscitation was performed with Ringer's lactate, 6% hydroxyethyl starch (HES) solution, or dog's plasma. ⋯ Resuscitation with HES solution and plasma did not result in increases in EVLWV, but with HES solution resulted in decreases in colloid osmotic pressure to pre-hemorrhagic levels in two hours. This suggests that the resuscitation with HES solution can not maintain colloid osmotic pressure for more than two hours. The author concludes that the hemodynamic and pulmonary effects of HES solution and plasma are similar in mild lung injury cases.
