title: Haemodynamic alterations during electroanaesthesia in young buffaloes. Comparative study of electric wave forms.
abstract: Sine, triangular and square wave alternating currents were used to anaesthetize young buffalo calves. Central venous pressure, systolic and diastolic blood pressure and circulatory rate were monitored before, during and after application of currents. The square and triangular wave current produced a significant (P less than 0.01) increase in central venous pressure, mean systolic and diastolic blood pressure during electroanaesthesia. The sine wave seemed to produce these changes to a lesser degree than the other wave forms. From the results of objective evaluation of the effects produced on these physiological values, the sine wave would be preferred to the other two wave forms for producing anaesthesia in buffaloes.
