Brief Summary:

This is a single-blinded multi-institutional randomized controlled trial to evaluate the effectiveness of Arista hemostatic matrix powder (Arista® AH, C. R. Bard, Inc. Davol, Warwick, RI) in reducing drainage output in anterolateral thigh (ALT) free flap donor sites. Increased drainage from donor sites can lead to seroma formation with possible secondary infection, delayed hospital discharge, and additional home care needs for drain care. Arista is an inert plant based absorbable surgical hemostatic powder that can be easily applied to broad surgical fields to reduce bleeding and seroma rates. Therefore, its application to free flap donor sites may bear significant potential benefit.

Specific Aim 1: The main hypothesis of the study is that the use of Arista in anterolateral thigh (ALT) free flap donor sites prior to closure will reduce postoperative drain outputs and time to drain removal compared to ALT donor sites closed without Arista.

Specific Aim 2: This study will also evaluate the secondary hypotheses that Arista will reduce postoperative ALT donor site seromas and patient hospital length of stay.

Official Title: Multi-Institutional Randomized Controlled Trial Evaluating Use of Arista Absorbable Surgical Hemostatic Powder in Anterolateral Thigh Donor Sites
Study Start Date : July 2016
Estimated Primary Completion Date : July 2021
Estimated Study Completion Date : July 2021

Arm Intervention/treatment
Experimental: Arista
Arista to ALT donor site
Device: ARISTA
According to the manufacturer, Arista uses Microporous Polysaccharide Hemospheres (MPH) technology to catalyze the clotting cascade and effectively dehydrate tissue to initiate hemostasis in broad areas. Major advantages of Arista are that it has been shown to be safe and effective across multiple surgical disciplines, is completely absorbed in 24-48 hours, and contains no human or animal components

No Intervention: Control
No Arista to ALT donor site

Primary Outcome Measures :
  1. total drain output [ Time Frame: 1-14 days after Surgery ]
    The primary outcome analyzed in this study will be total drain output (mL) in an effort to determine if the addition of Arista to the wound bed decreases overall wound drainage and drain output.

  2. Development of ALT donor site seroma. [ Time Frame: 30 days postoperative ]
    ALT donor site will be evaluated for seroma

  3. Timing to Drain Removal [ Time Frame: 30 days postoperative ]
    Given that drain output influences time of drain removal, assessment will be made to determine if timing of drain removal differs between groups.

Secondary Outcome Measures :
  1. Hospital Length of Stay [ Time Frame: 30 days postoperative ]
    Will eval hospital length of stay for both groups
