Effects of line type blood-liquid warmer on two different infusion sets

Objective: to investigate the source of 'bubbles' in infusion sets which were caused by the 'line type' blood-liquid warmers used in operation rooms to prevent hypothermia. methods: the experimental study was conducted from august to september 2012 at the thoracic surgery department of dokuz eylul university, izmir, turkey, by warming liquids in the operation room experimentally in a setting similar to clinical routine. initially, 0.9% sodium chloride solution was infused using s-line blood-liquid warmers with medisetin patients who were placed in group m). the ipc group had intrafix primeline confortset at a rate of 350ml/hour in the operating room. the initiation time and level of bubble formation, temperatures of the operation room, infusion liquid, s-line device, line of the device, and the liquid at the outflow were recorded. data was analysed with spss 15. result: the two groups had 10 subjects each. the temperatures of the working area, the liquid before and after being placed in the warming device, the proximal-middle and distal parts of the line and the set temperature on the screen of the device were similar and the difference between them was not statistically significant (p>0.05). while no bubble formation was observed in group ipc, bubbles were formed after 9.80±0.78 minutes and the level of bubble formation was close to 3 in group mediset (2.80±1.03). the main difference between the two groups was di (2-ethylhexyl) phthalate content of mediset. conclusion: infusion sets containing di(2-ethylhexyl) phthalate should not be used with warming devices in order to avoid toxic effects.
