Role of preoperative antibiotic prophylaxis in preventing postoperative peritonitis in newly placed peritoneal...

Area of Science:

• Nephrology
• Infectious Diseases
• Surgical Infection Prevention

Background:

• Peritonitis is a common complication in peritoneal dialysis (PD).
• The efficacy of preoperative antibiotic prophylaxis for preventing early infection after PD catheter placement is debated.
• Vancomycin and cephalosporins are used in PD peritonitis treatment, but their prophylactic role is unclear.

Purpose of the Study:

• To prospectively evaluate the effectiveness of single-dose preoperative intravenous vancomycin versus cefazolin in preventing postoperative peritonitis following permanent PD catheter placement.
• To compare the incidence of early peritonitis between antibiotic prophylaxis groups and a control group.

Main Methods:

• A prospective randomized study involving 221 patients (254 procedures) over 6 years.
• Three groups: Group I (vancomycin 1000 mg IV 12 hours pre-op), Group II (cefazolin 1000 mg IV 3 hours pre-op), Group III (no preoperative antibiotics for 1 week).
• Patients monitored for peritonitis for 14 days post-procedure.

Main Results:

• Peritonitis incidence: Group I (vancomycin) 1% (1/86), Group II (cefazolin) 7% (6/85), Group III (control) 12% (10/83).
• The vancomycin group showed a significantly lower peritonitis rate (P = 0.02).
• Single-dose vancomycin was more effective than cefazolin in reducing postoperative peritonitis.

Conclusions:

• Single-dose preoperative intravenous vancomycin prophylaxis is effective in reducing the risk of postoperative peritonitis in patients undergoing permanent PD catheter placement.
• Vancomycin prophylaxis demonstrates superiority over cefazolin in preventing early peritonitis after PD catheter insertion.
• The study highlights the significant risk of peritonitis associated with the absence of preoperative antibiotic prophylaxis.
