A deep cut that still feels 'fresh' 12–15 hours after the injury carries a high risk of both bacterial infection and tetanus. For an index finger laceration, we must assess not only the skin closure but also the underlying tendon function and digital nerve integrity. Immediate clinical wound management, including a Tetanus Toxoid (TT) booster and potentially primary closure (stitches), is the standard of care for a wound of this depth
Next Steps
Active Cleaning: clean the wound thoroughly with an antiseptic like Povidone-iodine or Dettol. However, avoid putting harsh chemicals inside a deep cut; sterile saline or clean running water is best for internal irrigation.
TT Booster: Obtain a Tetanus Toxoid (TT) injection immediately. This is a non-negotiable safety step for deep lacerations.
Surgical Review: , you should see a General Surgeon. They need to check if you can fully bend and straighten your finger; if you cannot, a tendon may be injured.
Antibiotic Cover: Given the depth and time elapsed, a short course of oral antibiotics and a topical antibiotic ointment are likely necessary.
Health Tips
A formal clinical consultation is mandatory to check for nerve/tendon damage and to decide if stitches are needed to prevent a permanent scar or functional loss."
