Sažetak
The possibility of reaching and blocking nerves at the incisura ischiadica major was studied in bovines and goat. Orientation points of approaching the bovine incisura ischiadica major are the processus spinosus of the second sacral vertebra, tuber coxae and processus spinosus of the third sacral vertebra, while tuber ischiadicum, tuber coxae, trochanter major and linea glutea serve as points of orientation in goat. In bovines the nerves can thus be reached from a line assumed to run through the processus spinosus of the second sacral vertebra 6-8 cm remote from the mid- plane ; at the intersection of lines relating the utmost lateral point of the tuber coxae with the top of the processus spinosus of the third sacral vertebra as well as at the upper point of an assumed equilateral triangle with the base joining the cranio-lateral part of the trochanter majus with the caudo-medial part of the tuber ischiadicum. The needle penetrates 8- 10 cm in depth and 40 ml 1% scandicaine were administrated. In goat, the nerves can be reached from the cranial third of a line assumed to run from the tuber coxae to the trochanter major ; from the mid-point of the line joining the tuber sacrale with the trochanter major ; along the medial margin of the linea glutea to the incisura ischiadica major. 10 ml 1% scandicaine were administered at depth 5-8 cm. Blockade symptoms of nerves passing over the incisura ischiadica major occur as soon as in 15-30 or 30-60 seconds in goat and bovines respectively, to be manifested as the weakness in the hind leg, leaning against the anesthetized leg, swaying, forceful step forward with the ankle joint not fixed and numb digits flexing and extending passively so that the animal drags the dorsal part of hoof along the ground. Caudal and caudo-lateral femoral muscles, croup muscles and muscles located distally from the knee joint get atonic. The skin of the caudal croup and hips as well as that located caudally and ventrally from the line crista iliaca - trochanter major - knee joint is insensible. The effect of the anesthetic gradually lessens to completely disappear in 100-120 minutes.
