When this product is used to prevent postoperative infection, it is generally intramuscularly injected or intravenously administered 1g 0.5-1 hour before surgery. If the operation time exceeds 6 hours, 0.5-1g is added during the operation, and 0.5-1g is added every 6-8 hours after surgery until 24 hours after surgery. The usual dose for children is 50-100 mg/kg per day, divided into 2-3 times for slow intravenous push, intravenous drip or intramuscular injection. Medication for patients with impaired renal function When the creatinine clearance of adults with impaired renal function is greater than 55 mL/min, they can still be given at normal doses; when the creatinine clearance is 35-54 mL/min, the regular dose is once every 8 hours or longer intervals; when the creatinine clearance is 11-34 mL/min, once every 12 hours, use 50% of the regular dose; when the creatinine clearance is less than 10 mL/min, once every 18-24 hours, use 50% of the regular dose. The first dose for all patients with varying degrees of renal impairment is 0.5 g. Please follow the doctor’s advice for medication details. When children with renal impairment use cefazolin, first give 12.5mg/kg, followed by maintenance doses. When the creatinine clearance is above 70mL/min, it can still be given at normal doses; when the creatinine clearance is 40-70mL/min, give it once every 12 hours at 60% of the regular dose; when the creatinine clearance is 20-40mL/min, give it once every 12 hours at 25% of the regular dose; when the creatinine clearance is 5-20mL/min, give it once every 24 hours at 10% of the regular dose.
