Comparative Study
Non-invasive blood pressure monitoring in preterm infants receiving intensive care.
It is essential to have regular, accurate blood pressure (BP) monitoring of sick preterm infants. Invasive direct arterial BP measurements are often recommended, but it was our clinical experience that such measurements may not be possible in all infants. We therefore assessed the proportion of infants receiving neonatal intensive care in whom reliable arterial BP measurements could be made, the accuracy of a non-invasive method (Doppler technique) and established a reference range of BP results related to postnatal age using this non-invasive technique. ⋯ Doppler systolic BP measurements correlated well with the accurate (non-damped) arterial results (r = 0.96, P less than 0.01). Systolic blood pressure was measured on all 44 infants daily for the 1st week using the Doppler technique and increased linearly with increasing postnatal age (r = 0.92, P less than 0.01) from a mean of 41.7 mmHg on day 1 to 49.3 on day 7. We conclude that Doppler non-invasive BP monitoring is a useful method for regular monitoring of sick preterm neonates as it can be applied accurately, unlike direct arterial monitoring, to all patients.

Managing psychological distress is a central treatment goal in Pediatric Intensive Care Units (PICUs), with medical and psychological implications. However, there is no objective measure for assessing efficacy of pharmacologic and psychological interventions used to reduce distress. Development of the COMFORT scale is described, a nonintrusive measure for assessing distress in PICU patients. ⋯ Criterion validity, assessed by comparison with concurrent global ratings of PICU nurses, was also high. Principal components analysis revealed 2 correlated factors, behavioral and physiologic, accounting for 84% of variance. An ecological-developmental model is presented for further study of children's distress and coping in the PICU.

To ascertain the profile of medical intensive care unit (MICU) utilization in the Singapore General Hospital, a prospective survey studying 162 consecutive patients admitted to MICU was conducted over a four-month-period spanning September through December 1990. While there was no racial predilection, male admissions (n = 98) outnumbered female (n = 64) by a ratio of 3:2. Male admissions averaged 56.7 +/- 1.9 years (mean +/- SEM) vs 56.4 +/- 2.69 years in female (p = 0.98). ⋯ This contrasts with a mortality rate of 34.7% for non-septic patients. The issue of culture negative sepsis needs to be addressed. As it stands, septic patients stay longer than non-septic ones.(ABSTRACT TRUNCATED AT 250 WORDS)

ReviewNeonatal intensive care. When and where is it justified?
There is a wide panorama of disorders in the newborn infant where neonatal intensive care has been proven effective in reducing mortality. Although modern neonatal intensive care can be very costly, short and simple interventions for support and resuscitation still can be highly beneficial. In reviewing the field of neonatal intensive care during the 1980s, it becomes evident that a major challenge for the future will be to apply physiological principles of great and proven value for the newborn baby to more simple devices. Only thereby can the technology of neonatal care defined as a complex of actions-not only equipment and techniques-become justified for future generations.
