Medication Summary

In addition to definitive therapy, urgently administer a regimen of antibiotics (eg, ampicillin, gentamicin, and clindamycin or cefotetan) whenever acute Meckel diverticulitis, strangulation, perforation, or signs of small bowel obstruction or sepsis are present.



Class Summary

Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the clinical setting.

Ampicillin (Omnipen, Marcillin)

Interferes with bacterial cell wall synthesis during active replication, causing bactericidal activity against susceptible organisms.

Clindamycin (Cleocin, Cleocin Pediatric, ClindaMax Vaginal)

Useful treatment for serious skin and soft tissue infections caused by most staphylococci strains. Also effective against entericaerobic and anaerobic flora, except enterococci. Inhibits bacterial protein synthesis by inhibiting peptide chain initiation at the bacterial ribosome, where it preferentially binds to the 50S ribosomal subunit, causing bacterial replication inhibition.

Gentamicin (Gentacidin, Garamycin)

If used in combination with an antianaerobic agent, such as clindamycin or metronidazole, provides broad gram-negative and anaerobic coverage. Dosing regimens are numerous and adjusted on the basis of creatinine clearance and changes in distribution volume.

Cefotetan (Cefotan)

Second-generation cephalosporin used as single-drug therapy to provide broad gram-negative coverage and anaerobic coverage. Half-life is 3.5 h. Inhibits bacterial cell wall synthesis by binding to ≥ 1 of the penicillin-binding proteins; inhibits final transpeptidation step of peptidoglycan synthesis, resulting in cell wall death.

Antibiotics have proven effective in decreasing rate of postoperative wound infection and improving outcome in patients with intraperitoneal infection and septicemia.
