The purpose of this study was to compare the accuracy of indirect ankle and brachial blood pressure measurements in a group of neurosurgical patients. Intra-radial cannulation was used for direct arterial pressure measurement. The correlations of the systolic and diastolic pressure between the indirect ankle and direct intra-arterial blood pressure was good. The coefficient of correlation for systolic and diastolic pressure were 0.95 and 0.81 respectively. The correlation between the indirect brachial blood pressure and direct intra-arterial blood pressure was also good. The coefficient of correlation for systolic and diastolic pressures were 0.94 and 0.87 respectively. It was concluded that the indirect ankle blood pressure measurement was a good method of assessing the blood pressures and should be used when the upper limb measurements were not possible.
