appointment to the patient than this. During the early years of his career the eye-surgeon is also very disappointed with his results after this operation if lie takes the trouble to find out how small the amount of improvement is and he feels inclined to abandon the operation. The common causes of failure are : (1) Iris adherent to cornea. (2) Too small an iridectomy. (3) Extensive opacity of ...

A STEROID compound 21-hydroxy-preghalf to one hour prior to anaesthesia. A nane-3, 20-dione sodium succinate 4-litre to 2-litre flow of nitrous-oxide (Viadril) has been used as an intravenous oxygen was administered during the placeanaesthetic. The changes in the electroencephalogram produced by this agent have been observed by Boyan et al. (1955) to be similar to the changes reported by Kierse...

THE PRESENT investigation is undertaken to show how the physiological properties of the plasma membrane at the node of Ranvier is modified by narcosis, the relatively refractory period and electrotonus. We have already dealt with this problem in previous papers (5, 6), and the present study confirms and expands the previous results.

I N the treatment of surgical diseases of the upper extremity, partly local and partly general anaesthesia are used. The opinion of Kochert, that local anaesthesia is advisable only when contra-indication of narcosis exists, is no longer accepted. We cannot lay down any general rule as to the best types of anaesthesia to be applied, for example, the age of the patient or his psychic disposition...

Van Wijk CH, Meintjes WAJ. Complex tactile performance in low visibility: the effect of nitrogen narcosis. Diving and Hyperbaric Medicine. 2014 June;44(2):65-69.) Background: In a task-environment where visibility has deteriorated, individuals rely heavily on tactile performance (perception and manipulation) to complete complex tasks. When this happens under hyperbaric conditions, factors like ...
