Comparative StudyEffect of fazadinium on respiratory functions and its correlation with neuromuscular transmission in children.
Effects of fazadinium in doses of 0.75, 1.0 and 1.25 mg/kg and pancuronium 0.1 mg/kg on respiratory functions (tidal volume, minute volume and inspiratory force) and correlation between respiratory functions and neuromuscular transmission were evaluated in 64 children aged 6 months to 12 years undergoing various types of elective surgery. Neuromuscular transmission was evaluated by a digitial EMG system using train-of-four stimuli calculating T1 and T4 ratios. Time to apnea, duration of apnea, time and mode of recovery of respiratory functions and neuromuscular transmission when spontaneous respiration started and recovered completely were recorded. ⋯ In the remaining patients recovery was complete within five minutes after reversal. Pancuronium could be placed between 1.0 and 1.25 mg/kg fazadinium regarding aspects other than speed of onset of effect. Neuromuscular transmission was still markedly depressed when spontaneous respiration started (T4/T1 of 7-24%) and recovered (T4/T1 of 35-57%) indicating that when recovery from neuromuscular blockade is to be evaluated clinically, adequancy of ventilation by itself should not be taken as a sign of recovery from the effect of relaxant.

Oculocardiac reflex is one of the trigemino-vagal reflexes, and is frequently observed during anesthesia for pediatric strabismus surgery. The reflex is greatly exaggerated in the presence of hypoventilation, hypoxemia and acidosis. ⋯ Several related reflexes are known, such as blepharocardiac reflex, oculorespiratory reflex, and the sudden infant death syndrome. Although the reflex can be prevented by a retrobulbar block or the administration of parasympatholytic drugs, well conducted anesthesia and cooperation with the surgeon is much more important.

The choice of anesthesia as a career by undergraduates in a Saudi university.
In order to find out the career preferences of Saudi medical undergraduates as they relate to anesthesiology, questionnaires were distributed and received from 40 pre-clinical students and 26 clinical students immediately after their two-week anesthesia posting. Almost half of the preclinical students made their final choice. None of the students in this group made anesthesiology a first choice, though about 67.5% had heard about anesthesia. ⋯ U. rotation was the most enjoyable part of their anesthesia posting. The student's suggestions for improvement in their posting included a longer period than the present 2 weeks and more opportunity to acquire the required clinical skills. The authors advise a positive drive to Saudi medical undergraduates to take up the specialty of anesthesiology as a career in order to correct the present shortage.
