Patients need topical anesthesia for many things, including injections, suturing, and wound cleaning. Topical anesthetics give physicians a safe, simple way to numb patients’ skin before a procedure.
The combination of benzocaine, lidocaine, and tetracaine (“BLT”) in gel form has proven to work well even for cosmetic procedures. Gel form lidocaine, adrenaline, and tetracaine (“LAT”) has also proven effective for facial and scalp lacerations. Moreover, BLT and LAT gels give physicians the option of using a non-controlled substance for patient pain relief.
