HYPERTENSION FOLLOWING ORTHOPEDIC-SURGERY IN CHILDREN

Five patients developed hypertension after undergoing orthopaedic surg ery. Three of four patients in whom serum renin was assayed had signif icant elevation, suggesting a possible renal-mediated etiology. Two pa tients required the addition of an angiotensin-converting enzyme (ACE) inhibitor to control hypertension while continuing the prolonged orth opaedic procedures. The need for careful blood-pressure monitoring of children undergoing orthopaedic surgery is emphasized in this article.
