- W3028891106 abstract "ObjectiveTo study the relationship between the exposure time of puncture needle of infusion bottle stopper and microbial contamination during clinical intravenous transfusion.MethodsA total of 600 cases from November 1, 2014 to January 31, 2015 who have received the clinical intravenous transfusion for investigation were selected.When replacing the infusion bottle (bag), inserting the puncture needle slowly across the bottle stopper and making the needle tip be canted to the transfusion bottle mouth (bag) of the rubber plug, gently squeezing the Murphy's tube until solution was not dripping, recording down the exposure time in the air of the needle tip from medicine droplet to the end. To dip the lower part with sterile swabs and culture the swabs in nutrient broth medium. Meanwhile, to replace the next bottle of medicine and get the remaining 2 ml of liquids into the culture broth medium, after 48 h, both of which medium were switched to blood plate culture cultivation for observing the general situation of the bacteria growth.ResultsAmong the 600 cases of clinical transfusion, 24 cases were positive for sterile swabs microorganisms culture, positive rate was 4.0%, among which microorganisms, 15 cases were gram-positive coccus, 3 cases were gram-negative bacillus, 3 cases were gram-positive bacillus and 3 cases were fungi. Correspondingly, 3 cases were positive for liquid broth culture, positive rate was 0.5% as the gram-positive coccus. The exposure time and broth microbial culture result was statistically significant, while the exposure time and medicinal broth microorganisms culture result possesses had no statistical significance.ConclusionsInserting the puncture needle across the bottle stopper could successfully reduce the liquid drug residues in the infusion bottle (bag), however, which might also cause time-dependent microbial contamination during the exposure process in the air.Key words: Infusions, intravenous; Microbial contamination; Puncture needle" @default.
