Local anesthesia.. Addition of epinephrine (adrenalin) reduces local blood flow, slows the uptake of local anesthesia and prolongs its effect



Many simple surgical procedures can be performed that do not interfere with the body's cavities and do not require muscle relaxation through local anesthesia. A caesarean section may also be performed under local anesthesia.
The local anesthetic drug chosen is lidocaine 0.5% with or without epinephrine.
Do not give more than 4 mg / kg body weight of pure lidocaine or 7 mg / kg body weight of lidocaine with epinephrine at a time.
The addition of epinephrine (adrenalin) reduces local blood flow, slows absorption of the local anesthetic drug and lengthens its effect.
It is necessary to be careful when using epinephrine for this reason, because the increase may result in ischemic necrosis. It should not be added to used injections for fingers or appendages.
