Foot Dislocation Medication
- Author: Christopher M McStay, MD; Chief Editor: Rick Kulkarni, MD more...
Medication Summary
Administer analgesia as appropriate. Ensure adequate coverage against tetanus. If dislocation is compound, broad-spectrum intravenous antibiotics are required. Generally, a cephalosporin is the drug of choice. Dirty wounds may need the addition of an aminoglycoside to target gram-negative organisms. Injuries heavily contaminated with soil or farmyard waste require penicillin to protect against Clostridium perfringens.
Analgesics
Class Summary
Pain control is essential to quality patient care. It ensures patient comfort, promotes pulmonary toilet, and aids physical therapy regimens. Many analgesics have sedating properties that benefit patients who have sustained injuries.
Fentanyl citrate (Duragesic, Sublimaze)
More potent narcotic analgesic with much shorter half-life than morphine sulfate. DOC for conscious sedation analgesia.
With short duration (30-60 min) and easy titration, excellent choice for pain management and sedation. Easily and quickly reversed by naloxone.
After initial dose, subsequent doses should not be titrated more frequently than q3h or q6h.
Oxycodone and acetaminophen (Percocet)
Drug combination indicated for relief of moderately severe to severe pain. DOC for aspirin-hypersensitive patients.
Oxycodone and aspirin (Percodan)
Drug combination indicated for relief of moderately severe to severe pain.
Hydrocodone bitartrate and acetaminophen (Vicodin ES)
Drug combination indicated for relief of moderately severe to severe pain.
Anxiolytics
Class Summary
Patients with painful injuries usually experience significant anxiety. Anxiolytics allow the clinician to administer a smaller analgesic dose to achieve the same effect.
Midazolam (Versed)
DOC for procedural sedation to aid in reduction of anxiety associated with fractures or dislocations. Provides antegrade amnesia. Dose q1-2h.
Sedative hypnotics
Class Summary
Procedural sedation for reductions may require a sedative hypnotic.
Propofol (Diprivan)
Phenolic compound. Sedative hypnotic agent used for induction and maintenance of sedation or anesthesia.
Antibiotics
Class Summary
Prophylaxis is given to patients with compound dislocations.
Cefazolin (Ancef, Kefzol, Zolicef)
First-generation semisynthetic cephalosporin that binds to one or more penicillin-binding proteins, arrests bacterial cell wall synthesis, and inhibits bacterial replication. Primarily active against skin flora, including Staphylococcus aureus. Total daily dosages are same for IV and IM routes.
Gentamicin (Gentacidin, Garamycin)
Aminoglycoside antibiotic used for gram-negative bacterial coverage. Commonly used in combination with both an agent against gram-positive organisms and one that covers anaerobes.
Used in conjunction with ampicillin or vancomycin for prophylaxis in patients with compound dislocations. Dosing regimens numerous and adjusted based on CrCl and changes in volume of distribution. May be given IV or IM.
Vancomycin (Vancocin)
Potent antibiotic directed against gram-positive organisms and active against enterococcal species. Used to treat septicemia and skin-structure infections. Used in conjunction with gentamicin for prophylaxis in patients with penicillin allergy with compound dislocations. May need to adjust dose in patients with renal impairment.
Ampicillin (Omnipen, Marcillin)
Used along with gentamicin for prophylaxis in patients with compound dislocations. Interferes with bacterial cell wall synthesis during active replication, causing bactericidal activity against susceptible organisms. Given in place of amoxicillin in patients unable to take PO medication.
Penicillin G (Pfizerpen)
Interferes with synthesis of cell wall mucopeptide during active replication, resulting in bactericidal activity against susceptible microorganisms.
