Description |
The study was conducted in 26 clinical cases of cows with traumaticpericarditis admitted to Veterinary College and Research Institute Hospital, Namakkal from March 2010 to March 2012. The animals were divided into four unequal groups viz. Group I, II, III and IV comprised of six, seven, seven and six animals respectively based on the pregnancy status. Non pregnant animals were selected for group I The anaesthetic protocol was formulated with xylazine hydrochloride, diazepam, midazolam, acepromazine maleate, guaifenesin and ketamine hydrochloride. The anaesthesia was maintained with isoflurane. The rectal temperature of animals in group IV was significantly lower compared to other groups during maintenance of anaesthesia which returned to baseline value after recovery. A significant reduction in heart rate was observed in group I and IV animals during maintenance of anaesthesia which returned to baseline value after recovery. Significant reduction in respiratory rate was observed after induction in all the animals which returned to baseline value after recovery. Mechanical ventilation was employed throughout the surgical procedure with standard settings. The saturation of peripheral oxygen (SPO2) and end-tidal carbon dioxide (ETCO2) levels were maintained within the physiological limits. In group IV there was a highly significant reduction in mean arterial pressure (MAP) during maintenance of anaesthesia and after recovery. The electrocardiography revealed ST segment prolongation and elevation of about 0.3 to 0.4 mV in all the animals with traumatic pericarditis compared to healthy cattle. A significant reduction in haemoglobin and total erythrocyte count was noticed after induction and during maintenance of anaesthesia in all the animals. A highly significant reduction of packed cell volume after induction and during maintenance in all the groups was observed. A highly significant increase in serum cortisol was observed after recovery in all the groups. The total leucocyte count, differential cell count, serum level of glucose, total protein, creatinine, serum urea, aspartate amino transferase, serum calcium, and serum potassium had no significant difference at different stages of anaesthesia in group II, III and IV and between the groups. The induction time for group I, II, III and IV were 1.83?0.17, 1.64?0.09, and 1.71?0.09 and 1.95?0.21 min, respectively. The extubation time for group I, II, III and IV were 8.63?0.22, 7.47?0.14, 7.43?0.17 and 7.58?0.24 min, respectively. Time for sternal recumbency for group I, II, III and IV were 45.00?1.83, 28.57?2.10, 26.43?1.43 and 36.67?1.05 min, respectively. Time for unassisted standing of group I, II, III and IV were 57.50?2.14, 37.86?1.49, and 38.57?1.43 and 49.17?1.54 min, respectively. The anaesthetic complications like salivation, ruminal tympany and regurgitation were encountered in group I, III and IV. However, ruminal tympany and regurgitation were not encountered in any of the animals of group II and the quality of anaesthesia was graded as excellent indicating that the anaesthetic protocol employed in group II was superior to others. Diazepam as a preanaesthetic agent along with guaifenesin ? ketamine hydrochloride induction and isoflurane maintenance was found superior to perform thoracotomy in cattle with traumatic pericarditis. |
