PEP is a critical intervention to prevent infection after a needle stick injury. It involves administering antiretroviral drugs to reduce the risk of HIV, HBV, or HCV transmission, ideally within hours of exposure, under medical supervision.
4.1 What is PEP?
Post-Exposure Prophylaxis (PEP) is an emergency medication regimen to prevent infection after potential exposure to blood-borne pathogens like HIV, HBV, or HCV. It typically involves antiretroviral drugs for HIV, hepatitis B immune globulin, and/or hepatitis B vaccination. PEP must be initiated promptly, ideally within hours of exposure, to maximize effectiveness. It is a critical component of needle stick injury management, aiming to halt the establishment of infection in the exposed individual.
4.2 Administration and Timeline
PEP should be administered as soon as possible, ideally within hours of exposure, to maximize effectiveness. The regimen typically includes antiretroviral drugs for HIV, hepatitis B immune globulin, and/or hepatitis B vaccination. The treatment duration is usually 28 days, depending on the exposure type and source patient’s infection status. Prompt initiation and adherence to the full course are critical to prevent infection. Monitoring for potential side effects and ensuring completion of the regimen are essential components of PEP administration.
Testing and Follow-Up
Required laboratory tests include blood screening for HIV, HBV, and HCV. Monitoring for infection involves regular check-ups and repeat testing at intervals to ensure clearance and health status.
5.1 Required Laboratory Tests
Following a needle stick injury, laboratory tests are essential to assess exposure risks. Initial tests include HIV antibody, HBV surface antigen, and HCV antibody screenings. Additional tests may involve liver function checks and complete blood counts. These assessments help identify potential infections early. Repeat testing is conducted at intervals (e.g., 6 weeks, 3 months) to monitor seroconversion. Timely results guide further post-exposure prophylaxis (PEP) and ensure appropriate medical intervention, minimizing long-term health risks for the injured individual.
5.2 Monitoring for Infection
