Overview
Brief Summary
This is a randomized control study of antibiotic uses in clean non prosthetic surgeries. One group will be given antibiotic prophylaxis, other will receive a placebo. The primary outcome will be the rate of surgical site infection in 2 groups.
Detailed Description
I will conduct a randomized controlled trial (RCT) of antibiotic prophylaxis versus placebo in clean, non-prosthetic, elective procedures. The intervention will be a single dose of prophylactic antibiotic (cefazolin): 2 gr in adults or 3 gr for patients weighing \>120Kg and 30mg/kg in children) within 30-60 minutes prior to skin incision. The control group will receive a similarly prepared placebo injection (water for injection) 30-60 minutes prior to incision. I will randomize patients in a 1:1 allocation ratio using a simple randomization. Patients will randomly pick an envelope with a number allocating to antibiotic prophylaxis or placebo. Patients and caretakers will be blinded to the intervention. The surgeon will also be blinded to the intervention. The antibiotic (or placebo) will be pre-mixed by the study investigator and administered by the anesthetist. Other preventive measures for surgical site infection (SSIs) such as effective surgical hand scrub, proper skin preparation with povidone and sterility of materials and instrument will be applied systematically in all groups. Dressing of the wound will be removed 48 hours after operation and no further dressing will be required. Patients will be followed for development of SSI documented by surgeon at discharge and will be called after 30 days of surgery to address any sign of SSI.

Arms & Interventions
Prophylaxis
The intervention will be a single dose of prophylactic antibiotic (cefazolin): 2 gr in adults or 3 gr for patients weighing \>120Kg or 30mg/kg in children given within 30-60 minutes prior to skin incision.
Intervention: Cefazolin
No prophylaxis
The control group will receive a similarly looking prepared placebo injection (normal saline placebos for injection) 30-60 minutes prior to incision.
Intervention: Placebos
Outcomes
Primary Outcomes
Surgical site infection
Time Frame: 30 days post operative
surgical wounds will be accessed for signs of surgical site infection at discharge by a treating surgeon and patients will be called 30 days after operation for signs of surgical site infection
Secondary Outcomes
- mortality(48 hours post operation)
- morbidity(48 hours post operation)
