Low Preoperative Albumin Levels Significantly Associated with Increased Risk of Wound Infection and Bleeding After...

Area of Science:

• Plastic Surgery
• Surgical Outcomes Research
• Nutritional Biochemistry

Background:

• Panniculectomy procedures have a high incidence of postoperative wound healing complications, reaching up to 56%.
• As these are elective surgeries, optimizing patient variables before the procedure is crucial for improving outcomes.

Purpose of the Study:

• To investigate the association between preoperative serum albumin and body mass index (BMI) with short-term postoperative complications following panniculectomy.
• To determine the independent impact of albumin and BMI on bleeding and wound infection rates.

Main Methods:

• A retrospective analysis of 1472 patients undergoing panniculectomy (CPT code 15830) from 2005-2019 using the ACS-NSQIP database.
• Multivariate logistic regression was employed to assess the relationship between preoperative serum albumin, BMI, and other factors with intra/postoperative bleeding and wound infection.
• Statistical significance was set at p < 0.01, with odds ratios adjusted for comorbidities.

Main Results:

• Lower preoperative serum albumin and higher BMI were significantly associated with an increased likelihood of wound infection.
• Each 1 g/dL decrease in albumin increased bleeding odds by 1.85 times and wound infection odds by 5.03 times (p < 0.0001).
• Albumin and BMI showed independent effects on complications, with a weak correlation (r = -0.28).

Conclusions:

• Preoperative serum albumin levels are inversely associated with postoperative bleeding and wound complications in panniculectomy patients.
• Elevated BMI also independently increases the risk of wound complications.
• Further research is warranted to explore the benefits of proactive albumin optimization in reducing surgical complications.
