The Mean

In Reply.— We appreciate the interest and comments of Drs Puccio and Soliani regarding our article "Blood Pressure Increase, Birth Weight Dependent Stability Boundary and Intraventricular Hemorrhage."1 In response, we address the following points: 1. Although mean blood pressure (BP) values greater than 100 mm Hg were observed in some of our patients, these were quite rare. The mean BP was found to be less than 60 mm Hg 99% of the time. Thus, unless one is recording BPs through long periods and sampling quite often, the brief spikes likely would not be observed.

To the Editor.— We have read with great interest the recently published article by Perry et al.1 The need to define "safe" blood pressure levels in the critically ill premature infants is a central topic in the prevention of intracranial hemorrhage. However, in Perry's paper maximum systolic blood pressure and maximum mean blood pressure values are much higher than those reported by previously published articles.2-4 High blood pressure values were reported by Lou and Friis-Hansen5 in nine newborns.

Transcutaneous Po2

The blood pressure (BP) and transcutaneous Po2, (TcPo2) changes associated with intensive care procedures were evaluated to determine whether responses differ between babies with and without periventricular-intraventricular hemorrhage (PV-IVH). Fifty-three inborn babies ≤1500 g were studied using a microcomputer-based monitoring system. With almost any procedure including a seemingly benign one such as a diaper change, peak systolic BP increased and TcPo2 decreased. However, responses to interventions did not differ between babies with PV-IVH and those without PV-IVH. Neither did these responses differ between those with birth weight ≤1000 g and >1000 g. When each baby's record was scanned for the highest peak systolic BP before diagnosis of PV-IVH or within 48 hours in those with no PV-IVH and their BP points plotted against birth weight, a stable region was evident wherein PV-IVH occurred at a lower incidence (13%). When peak systolic BP was beyond this stable region, the incidence of PV-IVH was significantly higher, 70% (P < .0001). The stability boundary for the maximum systolic BP is birth weight-dependent; the limit for the highest tolerable peak systolic BP is lower for the low-birth-weight infant. In over 70% of instances the highest peak systolic BP was associated with motor activities either induced by nursery procedures or spontaneous. We speculate that decreasing the frequency of intensive care interventions may decrease episodic BP increases to levels beyond the birth weight-dependent stability boundary where PV-IVH is likely to occur.

Influence Of Noise

Introduction: Noise is an unwanted sound heard by the hearers, which can trigger health problems if it continues to be exposed to a certain intensity. One of the health problems that can arise due to noise is the blood pressure increase. This study aims to analyze the influence of noise intensity and age to the blood pressure increase. Methods: This study was an observational study completed with cross-sectional design and analytics. The independent variables in this study were the noise intensity and age, while the dependent variable was the blood pressure. The sample collection of this study applied the total sampling method with 46 employees as respondents, i.e., 29 employees of the heavy-duty shop and 17 employees of the EHS Department in PT. Vale Indonesia. The data analysis was conducted by using the logistic regression statistical test with α-value of 0.05. Results: the noise intensity affected the increase of both systolic blood pressure (significance/p-value=0.00) and diastolic blood pressure (significance/p-value=0.01) with an odds ratio of the increase of systolic blood pressure (Exp (B) =9.75) and the increase of diastolic blood pressure (Exp (B)=5.76). Furthermore, the variable of age does not influence the increase of both systolic (significance/p-value=0.57) and diastolic (significance/p-value=0.41) blood pressures. Conclusion:  the rise of the blood pressure of the employees is affected by the noise intensity factor in the workplace. Keywords: noise intensity, age, blood pressure

Abstract: Apart from protection from very high altitude or influence of increased gravitational accelerations protective suits sometimes are used for another applications like supporting kinesitherapy. Because of some safety considerations connected with possible cardiovascular system overload and dangerous blood pressure increase we tested if these concerns are valid. Main aim ot presented research performed with participation of healthy volunteers was to confirm that use of High Altitude Protection (HAP) suit is safe in terms of increased cardiovascular.

Object The aim of the study was to analyze the outcome of surgical treatment for posthemorrhagic hydrocephalus in premature infants. Methods From 1990 to 2006, 32 premature infants underwent surgical treatment for posthemorrhagic hydrocephalus, and their charts were retrospectively reviewed to analyze the complications and outcome with respect to shunt revisions. Multivariate analysis and time series were used to identify factors that influence the outcome in terms of shunt revisions. Results The mean gestational age was 27 ± 3.3 weeks, and mean birth weight was 1192 ± 660 g. Temporary reservoir placement was performed in 15 patients, while 17 underwent permanent CSF diversion with a ventriculoperitoneal (VP) shunt. In 2 patients, reservoir tapping alone was sufficient to halt the progression of hydrocephalus; 29 patients received VP shunts. The mean follow-up period was 37.3 months. The neonates who received VP shunts first were significantly older (p = 0.02) and heavier (p = 0.04) than those who initially underwent reservoir placement. Shunts were revised in 14 patients; 42% of patients in the reservoir group had their shunts revised, while 53% of infants who had initially received a VP shunt required a revision. The revision rate per patient in the reservoir group was half that in the direct VP shunt group (p = 0.027). No patient in the reservoir group had > 2 revisions. Shunt infections developed in 3 patients (10.3%), and 2 patients in the reservoir group died of nonneurological issues related to prematurity. Conclusions Birth weight and age are useful parameters in decision making. Preterm neonates with low birth weights benefit from initial CSF drainage procedures followed by permanent CSF diversion with respect to the number of shunt revisions.
