Background While closed suction drains (CSDs) are still frequently employed in clinical practice, the supporting evidence is limited with some studies demonstrating a failure of routine CSD use in preventing hematoma or seroma. Nonetheless, CSD quantity and quality fluid assessment is still appreciated by clinicians to detect postoperative bleeding. This study investigates the value of routine CSD use, in breast surgery, to predict postoperative bleeding. Methods A retrospective, intra-individual analysis, of CSD fluid volumes between the hematoma side and the unaffected contralateral breast, was undertaken in patients (n = 20) with unilateral postoperative bleeding following bilateral breast surgery (2003-2018). Statistical analysis was undertaken to establish a minimum cutoff fluid volume that might assist in the detection of postoperative bleeding. To determine the usefulness of quality assessment of CSD fluid output by visual inspection, surgeons (n = 56) prospectively matched six eligible hemoglobin concentrations corresponding to pre-filled CSDs. Results Statistical analysis did not yield a clinically reliable cutoff fluid volume indicating postoperative bleeding. All six eligible hemoglobin concentrations were completely successfully matched to pre-filled CSDs by 30.4% (17/56) of surgeons. Conclusions This study questions the significance of routine CSD use to assist in the decision-making process to return to the theater and address postoperative bleeding. Quantity as well as quality analysis of CSD fluid output failed the reliability and diagnostic validity tests. Hemoglobin measurements in drain fluid specimens via blood gas analysis might contribute to the detection of postoperative bleeding.
