Objective: To evaluate the manual cleaning process of flexible intramedullary reamers using the adenosine triphosphate (ATP) surface and water test and to develop a cleaning protocol for flexible intramedullary reamers used in orthopedic surgeries. Method: Experimental field study, with quantitative data analysis, carried out at the Central Sterile Supplies Department (CSSD) of a public hospital in Eunápolis, in the interior of Bahia. 32 reamers were evaluated, used in 17 orthopedic surgeries, before and after the cleaning process, totaling 64 ATP measurements on the surface and lumen. As a cleaning parameter, the recovery of up to 200 Relative Light Units (RLU) was adopted. To process the data, the generalized estimating equation model was considered for the RLU measurements and a significance level of 95%. Results: When comparing the surface and lumen RLU of dirty and clean reamers, there was a significant reduction of 230,997.18 surface RLU and 152,842.54 water RLU (p<0.001). The average recovery of the RLU of the reamers after cleaning was 74.3 RLU for the surface and 90.3 RLU for the lumen. Conclusion: Manual cleaning of flexible reamers required additional steps to achieve the RLU recovery adopted in the study. The validation of the immersion time in the enzymatic detergent and the step-by-step procedures used in cleaning allowed the evaluation of the process and the elaboration of the protocol for manual cleaning of the reamers.
