RESUMO
Computerized monitoring in a neonatal intensive care unit allows continuous registration and complete storage of vital parameters. The stored data can be used for detailed retrospective analysis of critically ill patients and the graphical presentation of the vital parameters may lead to an earlier recognition of clinical deterioration. This computer system which can be established in any intensive care unit demonstrates the improvement in neonatal intensive care monitoring at low financial costs.

The solution behaviour of hydroxyzine in water and chloroform (in the strongly alkaline and the strongly acidic range) is utilized to extract it from animal material and to purify the extract. A concentration of 0.01 p.p.m. is detectable in liver, kidneys and muscular substance. 0.05 p.p.m. may be determined semiquantitatively by visual spot comparison. In milk, the detectable amount is 0.1 p.p.m. and 0.5 p.p.m. can be determined semiquantitatively. The recoveries of low concentrations of hydroxyzine are likely to be lower in milk samples than in organ samples.

When the herbicide chlormequat (chlorocholine chloride or CCC) was correctly used at 2 kg per hectare at the five-leaf stage of growth, the residues in wheat straw did not exceed 3 ppm. Such residual amounts remained unchanged after storage and pelleting. However, the feeding of contaminated straw pellets to cows did not result in contaimination of the milk detectable by a method which was capable of determining concentrations down to 0.05 ppm.
