Brief Summary

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.

Conditions

Abdominal Abscess

Outcome Measures

Primary Outcomes (1)

• 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.

  From initiation of systemic treatment until 1 month follow up

Secondary Outcomes (2)

• White Blood Count

  From initiation of systemic treatment until 1 month follow up

• Maximum Temperature From Initiation of Systemic Treatment Until 1 Month Follow up

  From initiation of systemic treatment until 1 month follow up

Study Arms (2)

Antibiotic Irrigation

EXPERIMENTAL

The drain will be irrigated twice/day with the above antibiotic solution for 7 days maximum

Drug: Gentamicin Sulfate Inj 20mg/2ml vial for injection; Drug: Clindamycin phosphate 6 mg/1ml for injection

Normal Saline Irrigation

PLACEBO COMPARATOR

The drain will be irrigated twice/day with normal saline

Other: Placebo

Interventions

Gentamicin Sulfate Inj 20mg/2ml vial for injection DRUG

Antibiotic Irrigation

Clindamycin phosphate 6 mg/1ml for injection DRUG

Irrigate surgical drain with total amount of 12 mg in 10 ml volume once daily for 7 days or until drain removal if less than 7 days of therapy.

Antibiotic Irrigation

Placebo OTHER

The placebo group will receive drain irrigation twice/day
