Interventional
Description of intervention(s) / exposure
Treatment: Drugs - metronidazole and cephalzolin

Experimental: Single dose of antibiotics - This group will receive one dose of IV metronidazole (12.5mg/kg up to 500mg) and cefazolin (25mg/kg up to 1g) in the pre-operative period and two post-operative IV 'doses' of normal saline 8 and 16 hours after the pre-operative dose, which will act as a placebo and facilitate blinding.

Active comparator: Three doses of antibiotics - This group will receive one pre-operative dose of IV metronidazole (12.5mg/kg up to 500mg) and cefazolin (25mg/kg up to 1g) and two post-operative doses of IV metronidazole (12.5mg/kg up to 500mg) and cefazolin (25mg/kg up to 1g) 8 and 16 hours after the pre-operative dose.


Treatment: Drugs: metronidazole and cephalzolin
IV doses of metronidazole (12.5mg/kg up to 500mg) and cefazolin (25mg/kg up to 1g). One dose for study arm, two for comparative arm.

Maximum age
17 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Patients who on operation are found to have 'complicated appendicitis' defined as an appendix that is gangrenous or perforated.
* Patients who pre-operatively appear to be acutely septic or for another reason require extended antibiotic therapy.
* Patients who, at operation, are found to have other pathology e.g. Meckel's Diverticulum, Intussusception; requiring surgical or medical intervention.
* Any patient whose guardian does not wish for them to participate in the study.
* Patients who have additional co-morbidities, including diabetes, immuno-suppression, cardiac, renal or liver failure.
* If the child continues to show sign of sepsis, in terms of fever, tachycardia, he/she will be discontinued from the study and be given additional doses of antibiotics, as clinically indicated.
