Analysis of blood pressure measurements from the brachial and radial arteries in children

Objective:To determine the relationship between brachial artery blood pressure and radial artery blood pressure in children and whether blood pressure measured from the radial artery can replace blood pressure measured from the brachial artery. Methods:Brachial and radial artery pressures in 105 children were measured using an electronic sphygmomanometer.Results:There was no significant difference between the average values of blood pressures of the brachial and radial arteries in the 105 children studied ( P 0.05). Linear regression and correlation analyses showed that there was a positive linear correlation between the systolic pressure of the brachial artery and the radial artery in the 105 children, as well as a positive linear correlation between the diastolic pressures of the brachial and the radial arteries. Conclusion:Blood pressure values from the radial artery can completely replace blood pressure values from the brachial artery. Author's address The People's Hospital of Gongshu, Hangzhou, 310003
