BACKGROUND
Blood loss estimation in a surgery is made by anesthesiologists by means of visual technique, which is not reliable because it can change depending on the judgement of every person, or his/her work experience, which is why it is considered something subjective. Therefore, the results obtained could lead to make mistakes with the exact amount of bleeding, mismanaging unnecessary hemoderived transfusions or administering unnecessary drugs.
OBJECTIVE
To compare the blood volume and its visual calculation between Anesthesiology residents and anesthesiologists.
MATERIAL AND METHODS
Prolective cross-sectional study which included 85 Anesthesiology residents and anesthesiologists. Diverse scenarios of bleeding were set, divided into gauze pads, compresses and jars, and each participant was asked to answer the poll.
RESULTS
There is no significant difference in the estimate of bleeding between the estimation made by residents and anesthesiologists.
CONCLUSIONS
The grade of studies or experience is not significant for the exact estimation of bleeding with visual technique.
背景
手术中的失血估计由麻醉医生通过视觉技术进行，但这种方法不可靠，因为它会因每个人的判断或工作经验而有所不同，这就是为什么它被认为是主观的。因此，所获得的结果可能会导致在准确出血量上出现错误，对不必要的血液制品输血管理不当或使用不必要的药物。
目的
比较麻醉住院医师和麻醉医生对血容量及其视觉计算的情况。
材料与方法
前瞻性横断面研究，纳入85名麻醉住院医师和麻醉医生。设置了不同的出血场景，分为纱布垫、敷料和罐子，要求每位参与者回答调查问卷。
结果
住院医师和麻醉医生的出血估计之间没有显著差异。
结论
对于通过视觉技术准确估计出血情况，研究水平或经验程度并无显著影响。
