Indirect blood pressure measurements were compared in 28 conscious cats using Doppler and oscillometric blood pressure-measuring devices. Ten cats were used to compare Doppler measurements between two examiners and 18 cats were used to compare Doppler and oscillometric measurements. The Doppler machine obtained systolic and diastolic blood pressure readings in 100% and 51% of attempts, respectively. With the oscillometric machine, systolic and diastolic blood pressure readings were obtained in 52% of the attempts. With the Doppler, measures of mean systolic blood pressure between two examiners were positively correlated, but there was no correlation for diastolic blood pressure measures. When comparing the results obtained by Doppler and oscillometric machines there was no significant difference between mean systolic blood pressure readings, but the oscillometric machine produced significantly higher estimates of diastolic blood pressure. In both cases, the standard deviations for the oscillometric machine were considerably larger than those for the Doppler machine. The first reading of systolic blood pressure obtained with the Doppler machine was an excellent predictor of the mean of five readings, but this was not so for the oscillometric machine. It took less than 5 min to obtain five readings in 37.5% of cases with the Doppler machine but this was true for only 5% of cases with the oscillometric machine. Two cats with ophthalmological lesions consistent with systemic hypertension were identified. In these two patients, systolic blood pressure measurements were between 200 and 225 mmHg when measured by Doppler, and between 140 and 150 mmHg when measured by the oscillometric machine. This suggests that a lower reference range for normal systolic blood pressure values should be used for the oscillometric device.

A non-invasive, non-culture-based method of determining urinary d-/l-arabinitol (d-/l-ARA) ratios was investigated as a tool for the diagnosis of invasive candidiasis in nosocomial paediatric infection cases. The study encompassed 138 children aged 4 days to 16 years (mean±sd=1.6±4.2 years) with congenital heart defects (91.4 %) or with rhythm disorders or circulatory failure (8.6 %). ARA enantiomers were detected by GC using an electron capture detector. Positive d-/l-ARA ratios were found for 11/11 patients with proven candidiasis and 17/19 patients with clinically suspected invasive candidiasis. Thirty children were undergoing antifungal chemotherapy. d-/l-ARA ratios (mean±sd) were 2.601±0.544 in hospitalized cardiac patients without fungal infection and 5.120±1.253 in those receiving antifungal therapy (P<0.001). The sensitivity of the method was 100 %, the specificity 97.2 %, the positive predictive value was 78.6 % and the negative predictive value was 100 %.

Introduction: Metabolically sensitive afferent fibers in skeletal muscle can signal an increase the sympathetic control of arterial blood pressure during exercise. This process, called the muscle metaboreflex, is augmented in adults with cardiovascular disease and contributes to exercise intolerance. The role of the muscle metaboreflex on blood pressure control in children with congenital heart defects (CHD) is not known. Hypothesis: We tested the hypothesis that the mean arterial pressure (MAP) response to the muscle metaboreflex would be augmented in children with CHD compared to healthy controls. Methods: Twenty-six children with CHD (11±2 years; males=14; females=12) and 21 age- and sex-matched controls (11±3 years; males=10; females=11) were studied. CHD diagnoses included Tetralogy of Fallot (n=7), pulmonary or aortic stenosis (n=3), hypoplastic left or right heart syndrome (n=5), Ebstien’s anomaly (n=1), atrial or ventricular septal defect (n=5), transposition of the great arteries (n=2), double inlet left ventricle (n=1), heart transplantation (n=2), tricuspid or pulmonary atresia (n=2), coarctation of the aorta (n=2), and dilated cardiomyopathy (n=1). Testing included a 3 min rest period followed by isometric handgrip exercise at 30% of maximal voluntary contraction for 2 min. Exercise was followed by 3 min of either a free flow control condition or circulatory occlusion to isolate the muscle metaboreflex. Beat-by-beat MAP was recorded using finger plethysmography. Analyses were completed using mixed designs factorial ANOVA with P < 0.05 as the level of significance. Data are mean ± SD. Results: During the free flow control condition, there was no significant difference in resting MAP (75±9 mmHg vs. 78±9 mmHg), exercise MAP (86±14 mmHg vs. 87±12 mmHg), or free flow MAP (72±10 mmHg vs. 78±9 mmHg) between children with CHD vs. controls, respectively ( P > 0.05). MAP significantly increased from rest to exercise and returned to resting levels during the free flow control condition for both groups. For the circulatory occlusion condition, there was no significant difference in resting MAP (73±11 mmHg vs. 74±8 mmHg), exercise MAP (84±15 mmHg vs. 81±11 mmHg), or circulatory occlusion MAP (79±13 mmHg vs. 79±13 mmHg) between children with CHD vs. controls, respectively ( P > 0.05). MAP significantly increased from rest to exercise and MAP remained elevated above resting levels during circulatory occlusion for both children with CHD and controls ( P < 0.001 for all). Conclusions: Post-exercise circulatory occlusion significantly increases MAP in children with CHD and healthy children, with no significant difference in the magnitude of the MAP response between groups. We conclude that children with CHD demonstrate a normal muscle metaboreflex during post-exercise circulatory occlusion.

Abstract Continuous non-invasive blood pressure measurements bear a high potential. Particular in Somnology they allow to derive comfortably the systolic and diastolic blood pressure from an electrocardiogram and a synchronous photoplethysmogram without sleep disruption. In this short article some possible problems of this method are discussed along overnight recordings with a SOMNOtouch NIBP device.
