Prophylactic antibiotics for penetrating abdominal trauma

Area of Science:

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

Background:

• Penetrating abdominal trauma involves breaching the peritoneal cavity, historically managed with laparotomy.
• Antibiotic use, initiated in World War II, reduced sepsis-related mortality but their prophylactic necessity remains debated.
• Historical data suggests varied infection rates based on antibiotic timing, with current guidelines favoring single pre-operative doses.

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:

• A systematic literature search was conducted across major databases including Cochrane, MEDLINE, Embase, and PubMed.
• Searches were comprehensive, with no restrictions on date, language, or publication status, last updated July 23, 2019.
• Inclusion criteria focused solely on randomized controlled trials comparing antibiotic prophylaxis to placebo or no antibiotics in penetrating abdominal trauma patients.

Main Results:

• The literature search identified no randomized controlled trials that met the specified inclusion criteria.
• Consequently, no trials were available for data extraction or analysis regarding antibiotic prophylaxis in this patient group.

Conclusions:

• Currently, there is a lack of high-quality evidence from randomized controlled trials to support or refute the use of prophylactic antibiotics for penetrating abdominal trauma.
• Further research, specifically well-designed randomized controlled trials, is essential to guide clinical practice and establish the role of antibiotics in preventing infections after such injuries.
