Analysis of Factors Influencing Postoperative Drainage Following Reduction Mammoplasty
Yuan Qin, Xingmin Hu, Xin Li, Xiaoli Wang, Zhen SongABSTRACT
Aim
To explore factors influencing postoperative drainage volume and duration after reduction mammoplasty for perioperative nursing.
Design
A retrospective analysis was conducted on 83 patients who underwent reduction mammoplasty between January 2023 and October 2025.
Methods
Patients' characteristics and parameters related to the surgery were recorded. Univariable and multivariable linear regression and correlation analyses were performed to identify the correlation between postoperative drainage and the variables.
Data Sources
Data were extracted from routine de‐identified electronic medical records.
Results
The mean postoperative drainage volume was 81.2 ± 80.4 mL, and the mean drainage duration was 2.5 ± 0.84 days. Preoperative activated partial thromboplastin time, operation time, intraoperative blood loss, and resected tissue weight were independent predictors of drainage volume. Body mass index, operation time, and blood loss independently predicted prolonged drainage duration.
Conclusion
Multiple perioperative factors jointly affect postoperative drainage outcomes after reduction mammoplasty. These correlational findings offer preliminary references for individualised perioperative nursing management.
Implications for the Profession and/or Patient Care
High‐risk patients may require targeted preoperative education and intensified drainage observation. Further studies are needed to verify the clinical effectiveness of such nursing strategies.
Impact
This study supplemented comprehensive perioperative predictors for postoperative drainage after reduction mammoplasty. The main findings identified several perioperative factors associated with postoperative drainage outcomes. These preliminary correlational results may provide reference for perioperative nursing and offer hypotheses for future clinical validation.
Reporting Method
This study followed EQUATOR guidelines and the STROBE statement for retrospective observational studies.
