The Difference

AbstractIntra-arterial blood pressure (IABP) measurement, although considered the gold standard in critically ill children, is associated with certain risks and lacks widespread availability. This study was conducted to determine the differences and agreements between oscillometric non-invasive blood pressure (NIBP) and invasive IABP measurements in children. Inclusion criteria consisted of children (from 1 month to 18 years) admitted to the pediatric intensive care unit (PICU) of a teaching hospital who required arterial catheter insertion for blood pressure (BP) monitoring. The comparison between IABP and NIBP was studied using paired t-test, Bland–Altman analysis, and Pearson's correlation coefficient. In total, 4,447 pairs of simultaneously recorded hourly NIBP and IABP measurements were collected from 65 children. Mean differences between IABP and NIBP were −3.6 ± 12.85, −4.7 ± 9.3, and −3.12 ± 9.30 mm Hg for systolic, diastolic, and mean arterial BP, respectively (p < 0.001), with wide limits of agreement. NIBP significantly overestimated BP (p < 0.001) in all three BP states (hypotensive, normotensive, and hypertensive), except systolic blood pressure (SBP) during hypertension where IABP was significantly higher. The difference in SBP was most pronounced during hypotension. The difference in SBP was significant in children <10 years (p < 0.001), with the maximum difference being in infants. It was insignificant in adolescents (p = 0.28) and underweight children (p = 0.55). NIBP recorded significantly higher BP in all states of BP except SBP in the hypertensive state. SBP measured by NIBP tended to be the most reliable in adolescents and underweight children. NIBP was the most unreliable in infants, obese children, and during hypotension.

BACKGROUND: Use of lower backrest positions occurs frequently and is a factor in the development of ventilator-associated pneumonia. OBJECTIVES: To determine the usual bed elevation and backrest position in a medical intensive care unit and their relationship to hemodynamic status and enteral feeding. METHODS: Data were collected in a 12-bed medical respiratory intensive care unit for 2 months. A protractor was used to measure the elevation of the head of the bed. Hemodynamic status was defined by systolic, diastolic, and mean arterial blood pressure measurements retrieved from each patient's flow sheet. RESULTS: The sample included 347 measurements of 52 patients. Mean backrest elevation was 22.9 degrees, and 86% of patients were supine. Backrest position differed significantly (P = .005) among nursing shifts (days, evenings, nights) but not for systolic (r = -0.04, P = .49), diastolic (r = 0.01, P = .83), or mean arterial blood pressure (r = -0.01, P = .84). Backrest elevation did not differ significantly between patients who were receiving enteral feedings and patients who were not (P = .23) or between patients receiving intermittent versus continuous nutrition (P = .22). CONCLUSIONS: Use of higher levels of backrest elevation (&gt; or = 30 degrees) is minimal and is not related to use of enteral feeding or to hemodynamic status. The rationale for using lower backrest positions for critically ill patients may be based on convenience, the patient's comfort, or usual patterns in the unit. However, the dangers of supine positioning and its relationship to aspiration and ventilator-associated pneumonia should not be minimized.

Arteriolar Diameter

Pial arteriolar diameter changes inversely with changes in systemic arterial blood pressure. Such changes are consistent with autoregulatory functions. These responses are reduced by a brief period of hypoxia followed by reoxygenation. By using an open cranial window preparation we assessed the changes in pial arteriolar diameters during blood pressure changes in rats induced by hemorrhage and reinfusion of blood, before and after a brief period of hypoxia. The slopes of the changes in pial arteriolar diameter as a function of mean arterial blood pressure were −0.47 ± 0.26 μm/mmHg (mean ± SD; 1 mmHg = 133.3 Pa) before hypoxia and −0.11 ± 0.23 μm/mmHg after hypoxia in the untreated rats. In ouabain-treated rats, corresponding slopes were −0.42 ± 0.24 and −0.46 ± 0.22 μm/mmHg. The observed protective effects of ouabain might be a blockade of the Na–K pump in the sarcolemma of the vascular smooth muscle.Key words: vascular smooth muscle, electrogenic sodium pump, metabolic inhibition.
