Causal analysis on infusion timeout of 5-fluorouracil powder injection infusion pumps and the optimization for dispensing methods / 中国实用护理杂志

ABSTRACT

Objective:To analyze the cause of infusion timeout of 5-fluorouracil (5-FU) powder injection infusion pumps, and conduct research on the dispensing methods, then provide a basis for clinical dispensing.Methods:The dissolution effect of 5-FU in different solvents were tested in the lab. The effect of different solvents on infusion timeout of infusion pumps, and the factors related to infusion timeout of the pumps were explored by analyzing the clinical data which was collected in Cancer Hospital of Shantou University Medical College from May 20 to July 20, 2020.Results:The dissolving capacity to 5-FU of different solvents sorted by the influence in a descending manner as follows water for injection> 5% glucose injection (5%GS) >0.9% sodium chloride injection (0.9%NS) . Infusion timeout value of water for injection group (15.03 ± 8.62)% was lower than that of 0.9%NS group (36.78 ± 4.81)%, (0.9%NS+ water for injection) group (22.50 ± 7.22)%, 5%GS group (25.53 ± 6.21)% and (5%GS+ water for injection) group (24.78 ± 4.36)% ( t values were 2.50-5.27, all P<0.05). The timeout value of 0.9%NS group was higher than that of other groups ( t values were 3.65-5.27, all P<0.05). There were differences in infusion timeout between intravenous infusion group (23.07 ± 8.98)% and arterial infusion groups (60.60 ± 58.64)% ( H=10.18, P=0.001). There was a positive correlation between drug concentration and infusion timeout( r=0.29, P=0.013), and a negative correlation between total liquid volume and infusion timeout ( r=-0.59, P<0.01). Infusion timeout of pumps was partly (67.3%) affected by drug concentration, total liquid volume and infusion route. Conclusions:The research shows that infusion timeout of 5-FU powder injection infusion pumps is related to drug concentration, total liquid volume and infusion route. It is suggested that the percentage of water for injection, drug concentration, total liquid volume, and infusion route should be considered when 5-FU powder injection infusion pumps are prepared.
