Abstract:
The primary aim of this study was to evaluate the effect of ropivacaine on respiratory rate by undertaking the proximal paravertebral regional block in calves. In this study twenty four calves were randomly distributed into four groups with six animals each based on different techniques - Groups A (anatomical land mark approach), B (peripheral nerve stimulator), C (ultrasound guidance) and D (ultrasound and peripheral nerve stimulator guidance). Respiration rate was monitored manually prior to procedure and thereafter at an interval of 1, 5, 10, 15, 30 minutes post-procedure and then on half hourly basis till 360 minutes. In all the groups, it was found that a significant increase in respiration rate was observed at 1 minute interval followed by a decrease in varying patterns until it became equal to the basal value by the end of observation. It was observed that ropivacaine 0.5% at the dose rate of 0.5 mg/ kg body weight had no significant effect on respiration rate in all the four groups. Therefore it was concluded that the selected dose of ropivacaine via proximal paravertebral block through all the four techniques was safe enough to prevent any untoward respiratory complications.
