Development and validation of a novel tool to estimate peri-operative blood loss.
Surgical blood loss predicts peri-operative outcomes. We have developed and validated Blood Loss Scores to estimate peri-operative blood loss during major abdominal surgery. ⋯ The score, taking into account suction fluid volume and haemoglobin concentration, explained more of the variance in the measured blood loss than the experts' assessment (77% vs 54%, p = 0.05) or the change in haemoglobin concentration (77% vs 11%, p < 0.0001). Addition of the change in haemoglobin concentration improved the estimate for the 24- and 48-h postoperative Blood Loss Scores to explain 78% and 80% of the variance of measured blood loss.
