Prophylactic antibiotics for penetrating abdominal trauma

Area of Science:

• Trauma Surgery
• Infectious Disease Prevention
• Evidence-Based Medicine

Background:

• Penetrating abdominal trauma breaches the peritoneal cavity, historically managed with laparotomy and antibiotics.
• Antibiotic use has reduced sepsis-related mortality, but their necessity for prophylaxis remains debated.
• Guidelines suggest single pre-operative antibiotics, with continuation for hollow viscus perforation.

Purpose of the Study:

• To evaluate the efficacy and safety of prophylactic antibiotics in preventing septic complications from penetrating abdominal injuries.
• To assess the impact on conditions like septicaemia, intra-abdominal abscesses, and wound infections.

Main Methods:

• Comprehensive literature search of multiple electronic databases (Cochrane, MEDLINE, EMBASE, PubMed, Web of Science) without date, language, or publication restrictions.
• Inclusion criteria focused on randomized controlled trials comparing antibiotic prophylaxis versus placebo or no antibiotics in patients with penetrating abdominal trauma.
• Literature search conducted independently by authors, with abstract screening for relevance.

Main Results:

• No randomized controlled trials met the inclusion criteria for this review.
• The current evidence base lacks studies directly comparing antibiotic prophylaxis against placebo or no treatment for penetrating abdominal trauma.

Conclusions:

• There is a significant lack of evidence from randomized controlled trials regarding the use of antibiotics for penetrating abdominal trauma.
• Current data cannot support or refute the routine use of prophylactic antibiotics in this patient population.
• Further high-quality randomized controlled trials are necessary to guide clinical practice.
