Final answer:
The most common prophylactic antibiotic used preoperatively is Cefazolin. It is a first-generation cephalosporin antibiotic that is effective against a broad range of bacteria and helps reduce the risk of hospital-acquired infections in surgical patients.
Step-by-step explanation:
The most common prophylactic antibiotic used preoperatively is Cefazolin. Cefazolin is a first-generation cephalosporin antibiotic that is effective against a broad range of bacteria. It is commonly used to prevent surgical site infections, including those associated with orthopedic, general, and abdominal surgeries.
Studies have shown that prophylactic antibiotics can significantly reduce the risk of hospital-acquired infections (HAIs) in surgical patients. The use of antibiotics before surgery helps to eliminate or reduce the bacterial load on the surgical site, decreasing the chances of infection.
It is important to note that the choice of prophylactic antibiotic may vary depending on the specific surgery and the patient's individual circumstances. The decision is typically made by the surgeon in collaboration with an infectious disease specialist or a pharmacist.
