 Background:It has been unknown whether an arterial line or a peripheral venous line is better for collecting blood for hemodilutional autologous blood transfusion(HAT).

 Methods:We used the electronic medical and anesthesia records of patients who underwent a unilateral total hip arthroplasty and received HAT at our hospital during the years 2017-2022. Of these 68 patients, 26 were excluded from the analyses due to incomplete data. We compared(i)the length of time required for blood collection,(ii)the frequency of hypotension(mean blood pressure≤65 mmHg), and(iii)the use of a vasopressor(ephedrine or phenylephrine)during blood collection between the arterial-line collection cases(Arterial group, n=25)and the peripheral venous-line collection cases(Venous group, n=17).

 Results:The blood collection time was significantly shorter in the Venous group(15[11-18]min, median[interquartile range])compared to the Arterial group(22[19-29]min)(p<0.05). There were no significant between-group differences in the frequency of hypotension or ephedrine/phenylephrine use during blood collection.

 Conclusions:These results suggest that a peripheral venous line is more appropriate than an arterial line for blood collection for HAT, as using the venous line enables significantly quicker blood collection.
