[Sterility in drained serums; before their use in emergency wards and in non-hospital emergency use].

The authors detail the characteristics for the sterility of drained serums placed in a mobile emergency service unit and they determine how much time they can maintain optimum conditions for the use of these serums by means of a controlled, random, triple blind clinical test in which the units studied were serums prepared by an infusion system and a three-way valve. Data were gathered during a 12 month study period. The authors designed six operating groups based on their exposure time and where they were kept.

Physico-chemical stability and sterility of previously prepared saline infusion solutions for use in out-of-hospital emergencies.

Objective: The topic of this research was to determine whether out-of-hospital emergency teams could make use of previously prepared saline solutions (SS). The objective was to discover the physical, chemical and sterility characteristics of previously prepared saline infusions stored in ambulances and ascertain how long they remained in optimum condition.

Method: Randomised clinical trial, triple blind, where study units consisted of saline solutions prepared with an infusion system and a three-way valve.
