ABSTRACT
PURPOSE:
Because there is little information on bleeding times (BTs) in children we initiated the following study. MATERIALS ANDMETHODS:
Normal children undergoing elective surgery and adult volunteers had their bleeding times measured with a disposable device (Simplate) with a vertical incision in the forearm. Results in children (four age groups) and adults, male and female, were compared.RESULTS:
The mean time in children was 270 s with a 95th percentile of 420 s compared with a mean time in adults of 320 s and a 95th percentile of 480 s (p = 0.001). Although the values in the various age groups and sexes were different, only sex had a statistically different value in adults.CONCLUSIONS:
The following reference values should be used for children 0-4 years, 4 +/- 1 min; boys > 4 years, 5 +/- 1 min; girls > 4 years, 5.5 +/- 1 min. We conclude that results obtained in children are significantly shorter than those obtained in normal adult subjects.
