PATIENT PROFILES OF RABIES PREVENTION

The following are scenarios where patients may have been exposed to rabies. Each situation is distinct, and an appropriate treatment approach requires a clear understanding of post-exposure prophylaxis (PEP) guidelines and options available.

Select from the options below to guide you to each individual profile.

Spencer, age 12

Potential Rabies Exposure:

While playing at a park with friends, Spencer went into a wooded area to retrieve a lost ball and encountered an aggressive raccoon. The animal attacked and Spencer fended it off by repeatedly kicking at it. Spencer, who had been wearing shorts, was left with multiple scratches on his right leg. A friend’s father brought Spencer to the ER.

 

Treatment scenario for this teen weighing 89 lb/40.4 kg:

Rabies PEP was administered based on the patient’s age and weight. The full dose of HRIG (5.4 mL) was administered carefully around all detectable wounds. A rabies vaccine was then injected intramuscularly into the deltoid muscle.

Weight: 89 lb/40.4 kg

Animal exposure: Raccoon

Wounds location: Right leg

Anton, 11 months


Potential Rabies Exposure:

A grandmother was babysitting her 11-month old grandson. While playing in the front yard, an unleashed dog came running over. Playful at first, it then aggressively pushed over the boy and bit him on both hands. Shocked, the grandmother called for an ambulance and they went to the ER.

 

Treatment scenario for this baby weighing 20 lb/9.1 kg:

Rabies PEP was administered (1.2 mL HRIG dose) based on the patient’s age and weight. Since the patient was young with low body weight – extra caution was taken to identify an appropriate HRIG product, its concentration, and any instructions for dilution, if needed.

Weight: 20 lb/9.1 kg

Animal exposure: Dog

Wounds location: Hands

Cassie, age 26


Potential Rabies Exposure:

Cassie was staying at a friend’s family vacation home and slept in a converted attic bedroom space. She woke early in the morning to the sound of something fluttering near the ceiling, but couldn’t see what it was. She then noticed 4-5 very small bite marks on her hand. After speaking to her friend’s family at breakfast, they decided to go to the ER to be safe.

 

Treatment scenario for this adult weighing 140 lb/63.5 kg:

Rabies PEP was administered (8.5 mL HRIG dose) based on the patient’s weight. HRIG was infiltrated thoroughly into and around all visible wounds and the remaining was given by the intramuscular route at a site distant from the site of the rabies vaccination.

Weight: 140 lb/63.5 kg

Animal exposure: Bat

Wounds location: Hand

Improper HRIG Administration Can Lessen the Effect of a Rabies Vaccine

Because HRIG can partially suppress active production of rabies virus antibodies, no more than the recommended dose should be administered.1,2

Is the Volume of Your HRIG Dose Adequate for Treating All Rabies Exposures?

Ready-to-Use KEDRAB® (Rabies Immune Globulin [Human]) at 150 IU/mL Potency Ensures You Have:

  • The appropriate volume needed to treat any rabies exposure
  • No need for dilution with dextrose, which may help reduce the potential for errors caused by the need to prepare an admixture1,3

 

Does a Higher Volume Increase the Chance for Compartment Syndrome?

In a prospective study involving 100 high-risk injections (fingers and toes), no case of compartment syndrome was found. The study authors never encountered any cases of compartment syndrome during the past 2 decades.4
