Brief Summary

The investigators conducted the study in 4 teaching hospitals and 2 non-teaching hospitals of Shaanxi Province. Surgeons, clinical pharmacists and nurses took part in patient collection, information registration, protocol performance.

The investigators recruited 1200 patients with inguinal hernia undergoing inguinal hernioplasty in the six hospitals from January 2010 to July 2011. The patients were randomly allocated into control group, cefazolin group and levofloxacin group, with digital meter method , 400 in each group. The data such as age, sex, case number, length of hospital stay, antibiotic usage, post-operative infection, infection site, bacterial culture were filled in self-designed forms on computer.

Detailed Description

All of the patients received tension-free inguinal hernia repair with a mesh plug. The surgical-site infection (SSI) was diagnosed according to the criteria of the Centers for Disease Control and Prevention [5-6].

We chose cefazolin sodium and levofloxacin sodium chloride injection as peri-operative antibiotics. Cefazolin sodium is an effective antibiotic with a short plasma elimination half-life against gram-positive cocci (GPC) except for enterococci and meticillin-resistant staphylococci. It is recommended as one of the prior antibacterial agents used for clearing cuts and preventing infection in many countries including China. Levofloxacin sodium chloride injection has a wide anti-bacterial spectrum composed of gram-negative bacteria and gram-positive anaerobic bacteria including anaerobic bacteria. It can remain a high concentration in urine, so it is recommended as an attractive antibiotic for urinary tract operation [5].

In the control group, we gave normal saline as placebo by intravenous drip infusion for 30-60 min before operation. Cefazolin group and levofloxacin group received intravenous administration of cefazolin sodium 1000 mg and levofloxacin sodium chloride injection 200 mg, respectively, for 30-60 min before operation.
