Study Notes
Therapeutic Classification
- Cefazolin (Ancef) is classified as an anti-infective, used to combat infections.
Pharmacological Classification
- It belongs to the first generation of cephalosporins, a group of antibiotics effective against certain bacteria.
Mechanism of Action
- The drug binds to bacterial cell wall membranes, leading to cell death, which makes it effective in treating bacterial infections.
Therapeutic Effects
- Exhibits a bactericidal action, meaning it kills susceptible bacteria.
Spectrum of Activity
- Actively targets many gram-positive cocci like:
- Streptococcus pneumoniae
- Group A beta-hemolytic streptococci
- Penicillinase-producing staphylococci
- Not effective against:
- Methicillin-resistant staphylococci
- Bacteroides fragilis
- Enterococcus
- Effective against specific gram-negative rods, including:
- Proteus mirabilis
- Escherichia coli
Dosage and Route
- For moderate-to-severe infections in adults, doses of 500 mg to 2 g every 6-8 hours, with a maximum dosage of 12 g/day.
- For mild infections with gram-positive cocci, doses of 250-500 mg every 8 hours.
- Specific dosages for:
- Uncomplicated urinary tract infections: 1 g every 12 hours.
- Pneumococcal pneumonia: 500 mg every 12 hours.
- Infective endocarditis or septicemia: 1-1.5 g every 6 hours.
- Perioperative prophylaxis: 1 g within 30-60 minutes before incision, with additional dosing as needed.
Critical Nursing Responsibilities
- Avoid confusion with similar drugs like cefotetan and ceftriaxone.
- For IM administration, reconstitute doses properly using sterile water for injection.
- Inject deeply into muscle; massage post-injection.
- For IV administration, monitor for signs of thrombophlebitis and change sites regularly.
- Do not use cloudy solutions; flush lines if multiple medications are necessary.
- Administer IV solutions carefully, respecting concentration limits and infusion rates.
Patient Teaching
- Educate patients to report signs of superinfection such as unusual tongue growth, vaginal issues, or changes in stool.
- Advise to inform healthcare providers of any rash or gastrointestinal symptoms, particularly blood in diarrhea.
- Warn patients against self-treating diarrhea without consulting a healthcare professional.
