The Relation of Proper Preparation of Solutions for Intravenous Therapy to Febrile Reactions*

Abstract

cordingly, rational parenteral therapy should be available in modern hospitals; and the volume, velocity, temperature, and composition of the injection may be left entirely to the discretion of the clinician. The intravenous injection of chemically pure, sterile solutions will not cause untoward reactions. FIG. i.-Arrangement of apparatus to facilitate the preparation of parenteral solutions. Distilled water, for immediate use only, is collected in an inverted pyrex carboy. The solutions are made by diluting a filtered concentrate gravimetrically. * Conductance, the reciprocal of resistance, is measured by the ratio of the current flowing through a conductor to the difference of potential between its ends. The practical unit of conductance, the mho, is the conductance of a body through which one ampere of current flows when the potential difference is one volt. Conductivity is measured by the quantity of electricity transferred across unit area per unit gradient,
