Interventions

NameTypeDescription
Catheter SclerotherapyDRUGPlace a drainage catheter of minimum 14F in caliber and obtain an antimicrobial sample. Saline lavage will be performed by irrigating the abscess and aspirating the contents until the character of the instilled and aspirated fluid are similar. Following this step the cavity will be drained in full and a volume of approximately equal to the cavity of povidone iodine or ethanol will be instilled through the catheter with the catheter turned off to drainage. After approximately two minutes the drain will be opened to gravity and two minutes of additional time will be allotted to drain any excess povidone iodine or ethanol. The catheter will then be removed, and the site dressed with gauze and film dressing. The patient will then be followed clinically in the hospital for at least 48 hours and by phone check in for 7 days.
