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).
