The visual compatibility of 30 drug additives with total parenteral nutrient (TPN) solutions (4.25% amino acids, 25% dextrose injection) was studied. For each drug additive, three TPN solutions were mixed; two were stored for 22 hours at 4 C then allowed to equilibrate to room temperature for two hours. Two 25-ml samples from each TPN solution were examined(More)
A chemical method for the determination of glycerol was developed and compared to an enzymatic assay for sensitivity and reproducibility. The chemical assay is based on glycerol oxidation to formaldehyde and subsequent reaction with chromotropic acid to yield a colored product. With this method, as little as 5 micrograms of glycerol/ml can be detected. The(More)
Background: Measurements of the optic nerve sheath diameter (ONSD) using bedside ultrasound (US) have been shown to correlate with clinical and radiologic signs and symptoms of increased intracranial pressure (ICP). Objectives: Previous literature has identified 5 mm as the ONSD measurement above which patients exhibit either clinical or radiologic signs of(More)
