Abstract

|
|
In this study, systolic & diastolic blood pressures obtained with indirect conventional sphygmomanometry were compared with direct measured blood pressures taken via arterial cannular during cardiac catheterization in 54 ventricular septal defect childrens from Jan. 1988 to Nov. 1988. Systolic & diastolic pressures of pre & post-cardiac catheterization were also compared each other.
The following results were obtained.
1. Conventional auscultatory systolic pressures of pre and post-cardiac catheterization and direct intra-arterial systolic pressures were 98.80± 11.85, 112.69± 17.09 & 106.37± 19.09 mmHg.
2. Conventional auscultatory diastolic pressures of pre and post-cardiac catheterization and direct intra-arterial diastolic pressures were 62.41± 9.75, 72.31± 14.19 & 64.98± 16.43 mmHg.
3. Indirect systolic and diastolic pressures of post-catheterization were higher than that of pre-catheterization by 13.89 mmHg(14.02％) and 9.9mmHg(15.86％) and there were significant difference.
4. Systolic pressures measured directly and by conventional method after catheterization correlated well(r=0.72). Indirect systolic pressures were higher than direct method by 6.23mmHg but there was no significant difference(P＜0.05).
5. Diastolic pressures measured directly & by conventional method after catheterization correlated poorly(r=0,33). Indirect diastolic pressures were higher than that of direct method by
