Comparative analysis of pain in patients who underwent total knee replacement regarding the tourniquet pressure.

Objectives: To evaluate through the visual analog scale (VAS) the pain in patients undergoing total knee replacement (TKR) with different pressures of the pneumatic tourniquet.

Methods: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard) and the other with systolic blood pressure plus 100 mmHg (P + 100). These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure.
