Single-antibiotic use for penetrating abdominal trauma
Abstract:
A prospective randomized study compared the use of moxalactam disodium vs clindamycin phosphate and tobramycin sulfate for treatment of 190 patients with penetrating abdominal trauma. Twenty-seven patients were disqualified because of early death or failure to follow the protocol. The patients in each group were comparable regarding the cause and severity of injury. No significant difference was seen in the incidence of intra-abdominal infection between the moxalactam-treated group (13%) and the clindamycin- and tobramycin-treated group (9%). The intra-abdominal infection rate in patients with colon injuries (21%) was significantly increased when compared with the patients without colon injuries (6%), but the antibiotic regimen did not significantly change the infection rate. No evidence of bleeding problems from moxalactam were noted. Changes in prothrombin and partial thromboplastin times appeared to be related to shock rather than the use of moxalactam. The most severe coagulopathies occurred prior to moxalactam therapy and were seen only in those patients who had shock requiring 10 or more units of blood. Moxalactam is as effective as combination (clindamycin and tobramycin) antimicrobial therapy in patients with penetrating abdominal trauma.
Insights
Moxalactam disodium is as effective as clindamycin and tobramycin for treating penetrating abdominal trauma. This study found no significant difference in infection rates between the antibiotic regimens, highlighting moxalactam
Area of Science:
- Infectious Diseases
- Surgical Infections
- Pharmacology
Background:
- Penetrating abdominal trauma presents a high risk of intra-abdominal infections.
- Effective antibiotic prophylaxis is crucial in managing these complex surgical cases.
- Comparing novel antibiotics with established regimens is essential for optimizing patient care.
Purpose of the Study:
- To compare the efficacy of moxalactam disodium against a combination of clindamycin phosphate and tobramycin sulfate.
- To evaluate the incidence of intra-abdominal infections in patients with penetrating abdominal trauma.
- To assess the safety profile of moxalactam, specifically regarding coagulopathies.
Main Methods:
- Prospective randomized study involving 190 patients with penetrating abdominal trauma.
- Patients were treated with either moxalactam disodium or clindamycin/tobramycin.
- Outcomes assessed included intra-abdominal infection rates and bleeding complications.
Main Results:
- No significant difference in intra-abdominal infection rates between moxalactam (13%) and clindamycin/tobramycin (9%) groups.
- Patients with colon injuries had a higher infection rate (21%) compared to those without (6%), irrespective of antibiotic regimen.
- No moxalactam-related bleeding issues were observed; coagulopathies were linked to shock and massive transfusion.
Conclusions:
- Moxalactam disodium demonstrates comparable efficacy to the combination of clindamycin and tobramycin for penetrating abdominal trauma.
- Antibiotic choice did not significantly alter infection rates in patients with colon injuries.
- Moxalactam is a safe and effective alternative for antibiotic prophylaxis in this patient population.
