Abstract

BACKGROUND:

The purpose of this study is to identify whether intraoperative use of vasoactive medications increases the risk of free flap failure or complications through a systematic review and meta-analysis.

MATERIALS AND METHODS:

PubMed/MEDLINE, EMBASE, and Scopus databases were searched for studies published through January 2015. English publications that met the following criteria were included: (1) adult patients undergoing head and neck free flap reconstruction; (2) comparison of patients with and without intraoperative vasopressor administration; and (3) documentation of flap failure rate and/or flap complications. The primary outcome was the incidence of flap failure. The secondary outcome was the incidence of overall flap complications. Meta-analysis was performed to obtain pooled odds ratios (ORs) of the effect of intraoperative use of vasopressors on flap failure and complication rates.

RESULTS:

Four cohort studies met inclusion criteria. All studies were of high methodological quality with an average Methodological Index for Non-Randomized Studies score of 18.75 (range 16-23). A total of 933 patients undergoing head and neck free flap reconstruction were included. Meta-analysis demonstrated no statistically significant difference in the incidence of flap failure (2.9 vs. 3.6%; OR, 0.68; 95% confidence interval [CI], 0.23-1.99; pā€‰=ā€‰0.48) or incidence of flap complications (16.8 vs. 18.6%; OR, 0.92; 95% CI, 0.60-1.42; pā€‰=ā€‰0.71).

CONCLUSION:

Based on the current evidence, intraoperative use of vasopressors has no impact on the incidence of flap failure or flap complications.
