Intra-abdominal abscesses are pus-filled pouches in the abdominal cavity. Current standard of care includes drain placement in the abscess cavity to reach source control as well as administration of systemic antibiotics. It is common practice to flush the drain on a daily basis to ensure patency. This study aims to analyze the clinical impact of a higher local concentration of antibiotics (rather than normal saline) provided through drain irrigation with an antimicrobial agent (Gentamicin and/or Clindamycin) compare to normal saline.
People with an abdominal abscess who undergo drain placement will have those drains irrigated twice/day with either normal saline (placebo group) or with the above antibiotic solution for a total of 7 days or less if the drain were to be removed earlier. Outcomes of interest are duration of systemic antibiotics, and WBC and temperature curve.

Duration of Systemic Antibiotics:
Total duration of systemic antibiotics will be recorded from the start of the treatment until discontinuation by primary care team. This will be measured as days from diagnosis to when the antibiotic treatment gets interrupted. Duration of systemic antibiotics will be our primary outcome measurement. Duration of systemic antibiotics will be monitored as an indication of the effectiveness of the proposed intervention.
Time frame: From initiation of systemic treatment until 1 month follow up
White Blood Count
White blood count level from the blood draw will be measured starting from the admission until discharge or discontinuation by primary care team. During follow up, if white blood count will be measured, will record up to 1 month follow up. The white blood count will be measured once daily and as needed depending on clinical changes. We will plan to trend WBC as another indication of decreasing systemic inflammation.
Time frame: From initiation of systemic treatment until 1 month follow up
Maximum Temperature From Initiation of Systemic Treatment Until 1 Month Follow up
Temperature will be measured every 8 hours starting from admission and until patient discharge. And also temperature will be measured during each follow up clinic visit. Change in temperature is monitored as an indication of decrease systemic inflammation.
Time frame: From initiation of systemic treatment until 1 month follow up
