Ambulatory blood pressure monitoring (ABPM) in adults is proving to be useful. The aim of this study was to determine if ABPM is accurate in the lower blood pressure range encountered in children and, equally important, whether it is acceptable to children. Thirty one children, between the ages of 6 and 18 years, were assessed using an ambulatory blood pressure monitor that uses an auscultatory method. Blood pressure was measured in the contralateral arm with a mercury sphygmomanometer and an oscillometric device at the beginning and end of the study for comparison. Over a blood pressure range of 90-130 mm Hg systolic and 40-80 mm Hg diastolic, a close agreement was found with the sphygmomanometer; the limits of agreement (+/- 2 SD) were 11.6 mm Hg for systolic blood pressure and 13.6 mm Hg for diastolic blood pressure. The bias was less than 1.0 mm Hg. The ambulatory device was worn by all patients for at least 16 hours with an average of 52 recordings per patient. The majority found the device comfortable to wear and were not woken from sleep. 相似文献

OBJECTIVE: To determine whether home care givers can accurately measure plasma sodium in children with diabetes insipidus (DI) by using an I-STAT portable clinical analyzer (PCA) and to collect preliminary data on home PCA use. STUDY DESIGN: Care givers of 4 children with DI and impaired thirst or inability to access water freely were instructed in PCA use. During an initial preclinical phase, the accuracy of sodium concentration measured by care givers was assessed by comparison to simultaneous analysis in a clinical laboratory. Participants were subsequently randomly assigned to daily home PCA monitoring or routine care. All participants crossed over from their original randomized group assignment to the alternate group. RESULTS: After a single education session, all care givers were able to perform PCA testing. There was good correlation between PCA and laboratory sodium (r = 0.92). On the basis of Error Grid Analysis, use of the PCA sodium would have resulted in treatment decisions identical to those made based on the laboratory sodium value in 62 of 66 instances. Four minor differences in treatment would have occurred. There was no statistically significant difference in clinical outcome during daily monitoring versus routine care. CONCLUSIONS: Results obtained by care givers using the PCA are sufficiently reliable for assessment of fluid status and making treatment decisions. 相似文献

Home, clinic, and ambulatory blood pressure monitoring in children with chronic renal failure 总被引:4,自引:0,他引:4
Ambulatory blood pressure monitoring (ABPM) provides superior information for diagnosis and treatment of pediatric hypertension, but for reasons of practicality, clinic blood pressure measurements (CBP) are still the primary diagnostic tool. Regular home blood pressure measurements (HBP) may be an alternative to ABPM, but this technique awaits validation in practice. We analyzed the concordance of ABPM, CBP and HBP in 118 pediatric patients (3-19 y) with chronic renal failure. HBP readings (10.5 +/- 5.4 per patient) were averaged for one week around the day of ABPM and CBP. Mean arterial pressure (MAP) measured by HBP (84.0 +/- 10 mm Hg) was significantly lower than both CBP (86.1 +/- 14.1 mm Hg, P< 0.05) and daytime ABPM (90.3 +/- 10.4 mm Hg, P< 0.05). HBP detected hypertensive patients with greater specificity (82 versus 70%), but lower sensitivity (52 versus 70%) than CBP. The fraction of patients rated erroneously hypertensive was 23% with CBP, but only 14% with HBP. The 95% limits of agreement with ABPM were narrower for HBP (-23 to10 mm Hg) than for CBP (-30 to 21 mm Hg). CBP, but not HBP measurements, were less precise in the upper BP range. The accuracy of HBP measurements did not change with use over a six months time period. In conclusion, HBP was superior to CBP in predicting ABPM, but neither CBP nor HBP detected hypertension with enough sensitivity or specificity to replace ABPM. The greater specificity of HBP compared with CBP makes it a more suitable tool for diagnosis, rather than screening, of hypertension in children. 相似文献

Recently there have been great advances in the use of ambulatory blood pressure monitoring (ABPM) in children. A major boost
has been the publication of normative data for blood pressure in children. ABPM has been able to detect significant differences
in blood pressure in many disease states including chronic renal failure, polycystic kidney disease and post renal transplantation
and has helped in identifying both white coat hypertension and masked hypertension. Current evidence does suggest that sole
reliance on clinic blood pressure might not be always appropriate and ABPM has a definite role in pediatric hypertension. 相似文献

Abstract: Objective: To evaluate 24‐h ambulatory blood pressure monitoring (ABPM) for early detection of hypertension in adolescents with type 1 diabetes mellitus (DM1). Design: Patients underwent fundoscopy, albuminuria determinations, two repeated autonomic cardiovascular tests, heart rate (HR) variation during deep breathing and blood pressure (BP) variation during sustained handgrip. Twenty‐four hour BP measurements were taken automatically by an oscillometric portable monitor. Setting: A specialty pediatric diabetes clinic and subjects' homes. Participants: Eighteen children aged 10–17 yr with 2+ yr of DM1, without long‐term complications, and 34 controls. Results: Higher ambulatory HR during the day than at night did not differ between DM1 subjects and controls. Mean systolic (s) and diastolic (d) BP in patients during the daytime were not significantly different from the control values. During the night, both sBP and dBP mean values in patients differed from those of controls. Statistical analysis of day and night HR and BP measurements were not different in both groups. The percentage decrease during the night in sBP and dBP was significantly smaller in patients than in controls. There were no differences by gender or duration of diabetes > or < 5 yr or by HbA1 above and below 10%. No difference in nocturnal sBP or dBP decline was observed between patients with or without abnormal autonomic test results. Conclusion: ABPM is more reliable than casual BP measurement in detecting early BP alterations during the night, before the appearance of microalbuminuria, in young patients with DM1. 相似文献

24 Hour ambulatory blood pressure monitoring (ABPM) was performed to provide data on the normal daily blood pressure of healthy schoolchildren and on patients with hypertension. The subjects studied were 123 healthy schoolchildren with a mean (SD) age of 12.5 (1.6) years (range 9.5-14.5 years), 24 children with borderline or mild hypertension, 17 with renal hypertension and normal renal function, 10 with chronic renal failure, and six with a renal allograft. In eight children with definite renal disease a second measurement was performed after treatment modification. The monitor used for ABPM was validated with a mercury column manometer. The mean (SD) of the signed differences of the blood pressure measured by the two methods was -0.19 (1.75) mmHg for the systolic and -0.21 (2.11) mmHg for the diastolic blood pressure (n = 60). Normal values for daytime and night time blood pressure were determined for those aged 10-14 years. The mean (SD) blood pressure of the 123 children was 109 (7)/66 (8) mmHg (systolic/diastolic) for the daytime and 96 (8)/52 (7) mmHg at night time. Of the 24 children with borderline or mild hypertension 14 had a raised blood pressure on ABPM. The circadian rhythm was disturbed in three children of this group. Even children with normal daytime blood pressure had significantly higher systolic blood pressure in the night when compared with the controls. The incidence of disturbed circadian rhythm was higher in the groups with renal hypertension (4/17 in the subgroup with normal renal function, 5/16 in the group with renal failure and/or transplantation). All children undergoing a second ABPM measurement had a lower average blood pressure after treatment adjustment. ABPM measurements were reproducible and accurate. The method provided new data on the physiological circadian variation of blood pressure in healthy children. It proved to be a helpful tool in the diagnosis of hypertension, particularly in the detection of cases of disturbance of the circadian rhythm of blood pressure pattern and individual adjustment of treatment. 相似文献

Ninety diabetic children each provided at least one 24-hour blood glucose profile at home using an impregnated filter paper strip. The mean 24-hour blood glucose level correlated significantly with urine control, height velocity, and Hb A1. The correlation coefficient for individual blood glucose values (r = 0.61) and for mean 24-hour blood glucose values (r = 0.73) repeated within 14 days showed an acceptable degree of reproducibility for the blood glucose profiles. Mean 24-hour blood glucose values fell significantly overall (11.4 to 9.8 mmol/l; 205 to 176 mg/100 ml) in 47 children who had repeated profiles more than 2 weeks apart. Unrecognised nocturnal hypoglycaemia (less than 3.0 mmol/l; 54 mg/100 ml) was found in 19% of children on twice-daily Semitard insulin. The study shows that children over age 7 years manage home blood glucose monitoring without difficulty. It shows that the results are reproducible and correlate with other indices of control, and that it provides a practical basis for the improvement of diabetic control. 相似文献

Blood pressure and heart rate were measured every 30 minutes during the day and every hour during the night in 43 children (20 girls and 23 boys, aged 10 to 16) with a portable automated monitor. The apparatus was better accepted in girls than in boys, and the failure rate was lower during the day. The overall failure rate was 22%, which corresponds with comparable studies in adults. During the night blood pressure and heart rate fell by 10% and 14% of the daytime values, respectively. Mean (SD) blood pressure was significantly higher in boys than in girls (126/72 (17/8) v 109/64 (9/5) mm Hg) and measurements correlated positively with age, body weight, and height of the subjects. Heart rate was not significantly influenced by gender or age. A positive correlation between heart rate and blood pressure was found when expressed as standard normal deviations or hourly variations. In children intermittent monitoring of ambulatory blood pressure and heart rate is a suitable method for measuring individual diurnal patterns. 相似文献

Blood pressure and heart rate were measured every 20 min during the day and every 30 min during the night in 105 children (51 girls and 54 boys, aged 6–10 years) with a portable automated blood pressure monitor using an oscillometric principle of measurement. The monitor was well accepted by most of the children and the rate of invalid measurements was only 13%. Mean systolic and diastolic blood pressure was 114±7/72±5 by day and 99±7/56±6 by night. The corresponding heart rates were 93±8 and 72±9 beats/min. No significant differences were found between boys and girls. At night, systolic blood pressure dropped by 13%±4%, the diastolic value by 22%±7% and heart rate fell by 22%±6%. Mean systolic and diastolic blood pressure measurements correlated positively with the subject's height, whereas no correlation was found with age. 相似文献

Over last two decades ABPM has evolved from a research device to an established and valuable clinical tool for BP evaluation. More than 10 yrs ago ABPM was introduced to pediatrics and since that time, its importance has been increasing in the management of hypertension in children and adolescents. This review summarizes the information gathered from the studies of ABPM in adult and pediatric patients with renal transplants. We will review the importance of hypertension in this patient subset, discuss the advantage of ABPM over CBP and focus on specific abnormalities and clinical significance of ABPM in renal transplant recipients. 相似文献

We evaluated the performance of continuous non-invasive finger arterial pressure measurement using the volume-clamp technique (Finapres). The study was designed to compare finger arterial pressure with brachial blood pressure estimated by the auscultatory method in 217 children (90 boys and 127 girls) aged 4–16 years and in 38 adults (aged 18–45 years). Finger and brachial artery pressure readings were obtained consecutively from the ipsilateral side in the supine position. Fingcr arterial pressure waveforms were recorded in all children except 4 with small and thin fingers. There was good agreement for systolic pressure with only a slight underestimation of 1.9 mmHg and 5.1 mmHg lower for diastolic pressure. This difference most probably reflects inaccuracy of the auscultatory cuff method rather than an error in the Finapres. There was large inter-individual variability in Finapres recordings which might be due to diffcrences in vasomotor tone, as demonstrated by systolic amplification in 5 patients with anorexia. However, Finapres showed a small within-subject variability (3.8 mmHg for systolic and 4.1 mmHg for diastolic pressure) dctermined in 5 patients during phenylephrine infusion, and as good reproducibility as the auscultatory method. These results suggest that finger arterial pressure measurement in children older than 6 years of age has similar accuracy as that in adults, and that this method is useful for clinical applications in children, especially for the non-invasive evaluation of autonomic control and cardiovascular reflexes involving transient and rapid blood pressure changes. 相似文献

Ambulatory blood pressure monitoring in children and adolescents 总被引:2,自引:0,他引:2
With recent technological advances, 24-hour ambulatory blood pressure (BP) monitoring (ABPM) has become a useful tool for the evaluation, diagnosis, and management of hypertensive children. It provides a more accurate representation of an individual's BP rather than intermittent casual or office BP measurements. Hence, ABPM is being used more often to assess the BP of children. In this comprehensive review, we provide the reader with the available literature on ABPM, discuss the advantages and limitations of ABPM, and the interpretation of ABPM data. The role of ABPM in various clinical conditions and hypertension research in children is presented. 相似文献

Aim: To compare BP measurements of children and adolescents using different methods office BP (OBP), ambulatory BP monitoring (ABPM) and home BP measurement (HBPM) and to study their correlations. Method: Individuals were evaluated between 5 and 15 years of age who had been referred because of a previous high BP. OBP was measured with the OMRON‐705CP. Three measurements were carried out at 5‐min intervals. HBPM were taken using the same device, two measurements at 5‐min intervals in the morning and in the evening during 7 days. ABPM was performed using the SpaceLabs 90207 monitors. Results: A total of 109 children and adolescents were evaluated (9.82 ± 2.63 years), 52.3% boys, 56.9% non‐white. The office systolic BP (SBP) was lower than in daytime ABPM (p < 0.001) but similar HBPM (p = 0.294), and the office diastolic BP (DBP) was lower than daytime ABPM (p < 0.001) and in HBPM (p = 0.035). The SBP and DBP at HBPM was lower than daytime ABPM (p < 0.001). Daytime ambulatory BP was more closely associated with home readings (SBP r = 0.731 and DBP r = 0.616) than with office’s readings (SBP r = 0.653 and DBP r = 0.394). Conclusion: The BP of children and adolescents varies depending on the place and manner of measurement. ABPM presents better correlation with HBPM than with the office measurements. 相似文献
