Perioperative risk factors for haematoma after breast augmentation.

Postoperative bleeding is the most frequent early complication after breast augmentation. The aim of this retrospective analysis was to assess possible risk factors originating in the perioperative management. All primary, bilateral breast augmentation procedures including augmentation mastopexy performed over an 8-year period were reviewed. Nine cases of postoperative bleeding could be identified in the 132 patients included in the study (6.8%). Univariate statistical analysis revealed age (p < 0.01), the amount of administered fluid intraoperatively (p < 0.05) and within the first 24 hours from the onset of anaesthesia (p < 0.01), the use of colloids (p < 0.01), total intravenous anaesthesia (p < 0.05), and systolic hypotension during the last 30 minutes of the operation (p < 0.05) as risk factors, whereas none of them could be identified as independent risk factor in multivariate analysis. In conclusion, this study was able to identify risk factors originating in the perioperative management that may lead to haematoma formation after breast augmentation.
