Normal values for neonatal blood pressure

In neonatal intensive care units where direct arterial blood pressures obtained via a transducer are unavailable, a fluid-filled spinal manometer has been used. The latter method is practical and convenient although its validity has not been confirmed. This study is designed to establish the precise relationship between the blood pressure obtained by the manometric method and by direct recording via the arterial transducer. Materials and Methods Eleven infants with umbilical artery catheters in place 1 to 2 cm above the diaphragm were selected for the study. In all instances, the arterial catheters were placed for clinical management of various illnesses.

A Prospective Study

The present study aimed to evaluate the occurrence of significant changes in systemic blood pressure (SBP) during surgical-dental procedures. A prospective study was performed with a sample of 135 randomly selected individuals who underwent surgical procedures at the Bucomaxillofacial Surgery Clinic of the Dentistry School of the ESFA (ES) between the second half of 2017 and April 2018. After consent, sociodemographic, lifestyle data, weight and height were obtained through a questionnaire, weighing and measurement, respectively. BP measurements were performed at three moments: preoperative (BP1), intraoperative (BP2) and postoperative (BP3) using a mercury column sphygmomanometer and stethoscope. Values <120/80 mmHg were used as normal values. When BP1 and BP2 were compared, 63.0% remained within normal values and 22.2% reached the stage of hypertension. In the comparison of BP1 and BP3, 66.7% remained normal, and only 7.4% reached the stage of hypertension. When BP2 and BP3 were compared, 53.6% remained within the normality stage and 12.2% reached the stage of hypertension. It was concluded that there were variations in blood pressure, being the largest variation found in BP2, and can be attributed to the stress caused by the surgical act, since no statistically significant connections were found between the changes in blood pressure and the anesthetics used in the research.

The Impact

Abstract Objective A comprehensive understanding of the factors contributing to perinatal blood pressure is vital to ensure optimal postnatal hemodynamic support. The objective of this study was to review existing literature on maternal and perinatal factors influencing blood pressure in neonates up to 3 months corrected age. Methods A systematic search of published literature in OVID Medline, OVID Embase and the COCHRANE library identified publications relating to maternal factors affecting blood pressure of neonates up to corrected age of 3 months. Summary data were extracted and compared (PROSPERO CRD42018092886). Results Of the 3683 non-duplicate publications identified, 44 were eligible for inclusion in this review. Topics elicited were sociodemographic factors, maternal health status, medications, smoking during pregnancy, and cord management at birth. Limited data were available for each factor. Results regarding the impact of these factors on neonatal blood pressure were inconsistent across studies. Conclusions There is insufficient evidence to draw definitive conclusions regarding the impact of various maternal and perinatal factors on neonatal blood pressure. Future investigations of neonatal cardiovascular therapies should account for these factors in their study design. Similarly, studies on maternal diseases and perinatal interventions should include neonatal blood pressure as part of their primary or secondary analyses.

Catecholamine Levels

Fifty-nine children with neurogenic tumors were examined for the presence of hypertension. Eleven of the 59 (19%) were found to have elevated blood pressure levels at the time of diagnosis or with progression of their disease. Several antihypertensive agents produced poor or only partial pressure control. All blood pressure levels returned to normal values after tumor excision or administration of effective antitumor therapy. There was no correlation of hypertension with urinary catecholamine levels. The etiologies of hypertension in children with neurogenic tumors are discussed.

Introduction: Myocardial work may provide a different perspective on LV function and energy consumption. Its non-invasive assessment by echocardiography correlates with invasive measures and there are normal values established in adult patients. We aimed to establish normal values in a healthy adolescent population. Methods: Nineteen healthy subjects (mean age = 15 ± 2 years, 42% male) with normal echocardiograms were prospectively included. Brachial cuff blood pressure was obtained immediately following apical images in the supine position. Post-processing of echocardiograms with speckle tracking echocardiography and derivation of global myocardial work indices from LV pressure-strain loops was done using EchoPAC (General Electric, v203R73.0) (Figure 1). Results: Baseline demographics, echocardiographic measures and global myocardial work indices are reported in Table 1. The mean global work index is 1833 ± 278 mmHg with mean global work efficiency of 95 ± 1.3%. No gender difference in myocardial work indices are found (p>0.05 for all). Correlation between global work indices with age, systolic blood pressure, LV ejection fraction, and global longitudinal strain (GLS) are presented in Table 2. Conclusions: This is a pilot study to begin establishing normal adolescent indices of non-invasive myocardial work. Figure 1. Example
