Summary
Needle-free jet injectors significantly reduce pain during local anesthesia for dermatologic procedures compared to traditional needles. This enhanced comfort does not compromise the procedure
Area of Science:
- Dermatology
- Anesthesiology
- Medical Devices
Background:
- Conventional local anesthesia uses hypodermic needles, often causing pain and anxiety.
- Needle-free jet injectors offer an alternative drug delivery system for improved patient comfort.
Purpose of the Study:
- Compare pain perception between needle-free jet injectors and conventional hypodermic needles for local anesthesia.
- Evaluate the efficacy and patient comfort during dermatologic procedures using both methods.
Main Methods:
- Prospective split-body study involving 35 adult patients with symmetrical skin lesions.
- Each patient received local anesthesia via conventional needle on one lesion and jet injector on the contralateral lesion.
- Pain was assessed using the Visual Analog Scale (VAS) during anesthesia and procedure.
Main Results:
- Mean pain score during anesthesia administration was significantly lower with jet injectors (2.20 ± 1.30) versus conventional needles (5.48 ± 1.82) (p < .001).
- Pain during the dermatologic procedure was minimal and comparable between both techniques, with no significant difference observed.
Conclusions:
- Needle-free jet injectors offer superior patient comfort for local anesthesia administration in minor dermatologic procedures.
- Jet injectors provide comparable efficacy to conventional needles for these procedures.

01:30Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

01:23Local Anesthetics: Common Agents and Their Applications
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
01:29Local Anesthetics: Clinical Application as Epidural Anesthesia
Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
