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.
