High Frequency Jet Ventilation is one in a group of alternative ventilatory techniques characterized by the application of small tidal volumes delivered at higher than physiological rates, followed by the passive expiration. There are two groups of indications: first, High Frequency Jet ventilation was used as a special ventilation mode during diagnostic or surgical procedures in patients with airway pathology; and second, High Frequency Jet Ventilation was employed as a respiratory support technique to improve gas exchange during severe pulmonary failure in infants, children and adults. Diagnostic or surgery laryngoscopy requires a method that can give good exposure of the larynx, continuing control of the airway patency and immobility of the vocal cords. ⋯ Jet ventilation via a catheter placed through the cricothyroid membrane, is an easy and safe way to ventilate patients with an abnormality of the upper airway, such as in cases of head and neck cancer. Inappropriate airway pressure monitoring and/or an insufficient expiratory airflow enhances the risk of pulmonary barotrauma. Despite a large body of published evidence describing its benefits as an alternative ventilatory approach in anaesthesia and intensive care medicine, its application has not gained widespread acceptance and is restricted to specialized centres only.

The most frequent incidences of blunt chest injuries occur due to motorvehicle accidents, falls and work-related traumas. Chest computed tomography is usually associated with examination of the subsequent regions with the aim to enable a more efficient diagnostic procedure. The purpose of this research study is to define the contribution of the chest CT in blunt injury patients. ⋯ The findings of this study coincide to a great extent with the findings presented in world literature.

The aim of this study is to show our experience in using the endo-extralaryngeal laterofixation of vocal cords in treatment of bilateral recurrent laryngeal nerve palsy, and to point out the difficulties and complications of this procedure and the ways of their managing. ⋯ Lichtenberger's endo-extra laryngeal laterofixation of the vocal cord is a good alternative method for bilateral palsy of the recurrent laryngeal nerve which provide sufficient upper airway without tracheostomy.

Laryngoscopy and tracheal intubation in patients undergoing surgical procedures under balanced general endotracheal anesthesia may provoke a sympathetic response with tachycardia and hypertension. ⋯ The results of this investigation indicate that intravenous bolus dose of remifentanil of 0.5 microg/kg, combined with thiopental, reduces the cardiovascular response to laryngoscopy and tracheal intubation, whereas bolus doses of remifentanil, 1 and 1.5 microg/kg, provide cardiovascular stability, as well as safe and efficient induction of anesthesia.

The prevalence of migraine in childhood and adolescence has not changed to a great extent, but it increases in adolescence, especially in female adolescents. MENSTRUAL MIGRAINE--DEFINITION: There are two types of menstrual migraine: true menstrual migraine and menstrually related migraine. True menstrual migraine occurs predominantly around menstruation, whereas menstrually related migraine occurs during menstruation, but also at other times during the month. ⋯ Hormonally associated migraine is a specific clinical entity. It is important to diagnose the type of migraine, considering the fact that a decline in estrogen level at the end of menstrual cycle triggers migraine, so it can be treated by low levels of estrogen.
