Background And Purpose:
To explore the feasibility of the modified blood collection method in pre-deposit autotransfusion in patients undergoing thoracotomy surgery.
Methods:
This double-blinded randomised controlled trial enrolled 92 patients from the cardiothoracic surgery department from February 2019 to October 2020.
Results:
Compared with the conventional blood collection method, the modified blood collection method avoided blood overflow from the oblique plane of the needle (χ2 = 61.986, P < 0.01) and reduced the diameter of the bruising area after 24 hours (χ2 = 24.611, P < 0.01). Furthermore, due to optimising the blood collection method, diastolic blood pressure reduced slightly before and after blood collection (t = 2.036, P < 0.05), and patients in the test group had less pain (based on the numerical rating score) (t = 5.556, P < 0.01). Meanwhile, the time required to collect 400 mL of blood was shortened (t = 17.744, p < 0.01).
Conclusion:
An improved blood collection method can enhance the blood donation experience, avoid blood spillage, lessen pain and reduce adverse reactions. This may be of great significance in ensuring blood quality and the safety of subsequent transfusions.
