The traditional metal syringe is restricted to 1.7ml or 1.8ml cartridges which must be reloaded when additional anesthetic is needed. In using the Anutra Syringe®, you have the ability to precisely draw up the amount of anesthetic that is required.

What is Buffering?

Buffering is a chemical process that neutralizes acids and bases. The Anutra Local Anesthetic Delivery System utilizes buffering to bring the pH of lidocaine with epinephrine closer to the physiological pH by precisely mixing the anesthetic with sodium bicarbonate.

Understanding Local Anesthetics

Unbuffered Lidocaine with Epinephrine

Lidocaine with Epinephrine is a local anesthetic commonly used by medical professionals. In order for it to be stabilized to ship, hydrochloric acid is added. In turn, this means that the solution being injected into a patient’s body is very acidic. Not only can this leave a burning or stinging sensation, it can take a good deal of time to numb the patient with a possibility that the patient may not even get numb the first time.

Buffered Lidocaine with Epinephrine

By adding sodium bicarbonate to lidocaine with epinephrine, a medical professional is able to reduce the amount of acidity found in unbuffered lidocaine. The result of buffering lidocaine with epinephrine can increase a clinician’s efficiency and can also reduce a patient’s pain. There is an increased likelihood that a patient will become numb more quickly and be numbed more deeply with buffered anesthetics.

Why Buffer Local Anesthetics?

Increased Predictability of Numbing

Buffering can elevate the depth of anesthesia increasing the likelihood of patients getting numb the first time.

Efficiency in Your Schedule

Buffered anesthetics can cross the nerve membrane more readily allowing a patient to become numb quickly.

Can Reduce Patient Pain

Buffering can lower the high level of acid typically found in local anesthetics which can reduce the burning pain after injection.
