Results
The samples required to evaluate the amount of insulin adsorbed to PP
bags were collected simultaneously from 6 separate infusion bags. In the
analysis of these samples, the insulin concentration rate of 100% was
accepted at baseline (0 hours). The insulin concentration rates of the
samples taken from PP bags at the 1st, 2nd, 4th, 12th, and 24th hours of
the infusion were determined as 95%, 98%, 98%, 95%, and 100%,
respectively (Table 1).
The samples required to evaluate the amount of insulin adsorbed to the
PVC infusion set were collected simultaneously from the end tips of the
6 separate infusion sets. The insulin concentrations of the samples
collected at the 1st, 2nd, 4th, 12th, and 24th hours of the infusion
were determined as 43%, 40%, 30%, 21% and 35%, respectively (Table
1).
To evaluate the stability of the insulin solution at room temperature,
the insulin concentrations of the solutions in PP bags stored at room
(+25°C)and at refrigerator (+4°C) temperatures were compared. The
insulin concentration in the PP bag, stored at + 4° C, was initially
considered 100% (0 hours). No statistically significant difference was
found between the concentrations of the samples taken from the bags
stored at room and refrigerator temperatures at the 4th, 12th, and 24th
hours (p>0.05) (Figure 1).
