Sir.—A recent article in the October 1987 issue of AJDC by Wareham et al1 demonstrated wide 95% prediction intervals (17 to 21 mm Hg) for systolic, diastolic, and mean blood pressures (BPs) as recorded by an oscillometric BP monitoring system (Dinamap 1846) in premature newborns and advised cautious interpretation of the Dinamap BP readings in this age group. It is an interesting finding in the presence of a number of articles confirming the accuracy of Dinamap BP measurements in full-term neonates (references 2 through 7)1 and in infants and children aged 1 month through 16 years.2 In fact, we have found the Dinamap method to be a better predictor of intra-arterial BP than the conventional auscultatory readings obtained by research nurses.2 However, on close inspection of our data, we find a trend of diminished accuracy of the Dinamap readings when arterial pressures were in the
