Abstract: In this case report, a sudden devoloped ventricular fibrillation following Pentothal anaesthesia in a dog and the treatment done was subjected. No abnormal findings were detected according to haemotologic and biochemical tests and ECG obtained at the preoperative period. Blood gases analysis and ECG monitoring were performed before anaesthesia induction for this experimental surgery. After the case was premedicated with Xylazine hydrochlorid (2mg/kg im), anaesthesia was induced by pentothal (Thiopental sodium 15 mg/kg iv). Following respiratoric depression, the dog was entubated and connected to the volume respiratory device. The dog was ventilated with 40% oxygene-air mixture 16 per minute. At the 5 th . minute after induction, fibrillation traces were seen on ECG without any evidence and arterial pressure traces was disappeard on the monitor. These changes couldn't have recorded because the fibrillation was developed suddenly. Resusitation was beginned by performing external heart massage 30 per minute, ventilation was followed with %100 oxygene. Lidocaine HCl were injected iv and defibrillation was repeated with 50 Joulle, then pressure traces were reappeared. External heart massage was stopped after arterial pressure had reached over 50 mmHg. When the vital signs had become normal, experimental operation was performed and the dog was extubated. No abnormal signs were detected during postoperative observation period.
