Background: Biosafety conditions in the surgical field are a current and constantly evolving problem. The risks and accidents that occur in hospitals in the presence of protection measures reveal an inadequate application of biosafety regulations by the nursing personnel. Based on this observation, the following research question was formulated: What is the level of application of biosecurity measures for the management of body fluids of patients during the perioperative period by the nursing staff of the operating room service at the Naval Medical Center?. Objective: To evaluate the level of compliance of biosafety measures for the management of body fluids of patients during the perioperative period by the nursing staff of the operating room service at the Naval Medical Center, through the collection and analysis of information that contributes to the improvement of medical practice and the avoidance of complications that endanger the life and integrity of surgical personnel. Method: A prospective study was conducted on a population composed by nurses of the operating room service at the Naval Medical Center. Given the health emergency caused by COVID-19, this evaluation was carried out remotely by electronic media. Through these channels, a link was sent in order to capture the questionnaire online on the Google Forms platform. Attempts were made to always preserve the confidentiality of the participant and to attend to ethical considerations. Results: The population under study consisted of 43 (74.1%) women and 15 (25.9%) men. The age group with the greatest presence was the one ranging from 30 to 39 years old, with 30 participants included (51.7%), followed by the range from 40 to 49 years old, with 19 cases (32.8%), and the one from 40 to 59 years, with only three cases (5.2%). General nurses represented 37.9% of the sample (n = 22); in contrast to the 36 specialists (62.1%). Compliancewithbiosecuritymeasureswas 88.7%. Conclusions: The hypothesis was confirmed by observing that the occurrence of the application of biosafety measures for the management of body fluids carried out by the nursing staff was greater than 73%. Some measures in which almost 100% compliance was achieved were hand washing (99.2%) and use of gloves (99.7%). In contrast, the measures with the lowest application frequency were handling of sharp material and / or waste (78.4%) and use of aprons (71.2%). The latter was the only item that did not exceed the percentage expected in the hypothesis.
