Twelve healthy dogs were used to measure the PI and the PSV under the conscious state and isoflurane anesthesia. The pulsatility index PI and the peak systolic velocity PSV in the basilar artery were measured five times with random intervals. The blood pressure was measured. The PI and PSV values in dogs under isoflurane anesthesia were and 72 19 cm sec whereas those in the conscious dogs were and 81 16 cm sec respectively. The indirect mean arterial systolic and diastolic pressures under isoflurane anesthesia were 107 and 51 mmHg whereas those in the conscious dogs were 133 and 74 mmHg. Though the isoflurane is generally known to induce hypotension there were no significant differences in the PI and PSV between the isoflurane-anesthetized and the conscious dogs. In conclusion the isoflurane anesthesia did not influence the PI and PSV in the basilar artery of dogs.
