ELECTROMYOGRAPHY IN GENERAL ANAESTHESIA

Electromyography in General Anaesthesia by B. Raymond Fink

A PRIMARY objective of general anaesthesia is to depress skeletal muscular responses sufficiently for smooth completion of a surgical procedure. The drugs used for this purpose are either general depressants of the central nervous system or selective depressants of motor impulse transmission to striated muscle. In both cases the extent of the depression of skeletal muscle activity is a principa...

General Anaesthesia in Cattle

General anaesthesia is the controlled and reversible loss of consciousness, which is helpful in ruminants for many surgical procedures that warrant effective control of pain and movement. General anaesthesia is indicated when the demands of technical and anatomical aspects of surgical procedure exceed the capabilities of sedative drugs and local analgesia. Moreover, the patient co-operation and...

Cerebral Oximetry in General Anaesthesia.

General anaesthesia in ophthalmic surgery.

MANY ophthalmic operations can be performed under local analgesia and this technique is used with satisfaction in all parts of the world today; in fact many surgeons and consultant anaesthetists are satisfied that the best results are obtained by this method. On the other hand, general anaesthesia is used much more than formerly and in some centres it is used routinely for most operations, incl...

General anaesthesia for neurosurgery.

Anaesthesia for neurosurgery, especially intracranial operations, requires conditions which maintain the perfusion of the brain with blood. This perfusion results from the cerebral perfusion pressure: the difference between the arterial and the intracranial pressures. Anaesthesia must also facilitate surgical access by reducing brain volume and minimizing surgical haemorrhage. Other common prob...
