Effect of Thermomechanical Stimulation on Pain During IANB Injections
Anesthesia Progress
|September 9, 2025
Summary
A thermomechanical device significantly reduced injection pain in pediatric dental patients receiving inferior alveolar nerve blocks (IANBs). This study confirms the device
Area of Science:
- Pediatric Dentistry
- Pain Management
- Anesthesiology
Background:
- Limited research exists on thermomechanical devices for reducing injection pain in pediatric dentistry.
- Inferior alveolar nerve blocks (IANBs) are common dental procedures that can cause significant pain in children.
Purpose of the Study:
- To evaluate the effectiveness of a thermomechanical device (Buzzy) in alleviating pain during IANBs in pediatric patients.
- To compare pain levels with and without the use of the thermomechanical device.
Main Methods:
- A randomized crossover study included 30 children aged 5-8 years requiring bilateral IANBs.
- Pain was assessed using the Wong-Baker Faces Pain Rating Scale (subjective) and the Faces, Leg, Activity, Consolability, Cry (FLACC) scale (objective).
- Participants received IANBs with and without the device in a randomized sequence with a 1-week washout period.
Main Results:
- The thermomechanical device group showed statistically significant reductions in both subjective and objective pain measures (P ≤ .00016).
- No significant differences in pain ratings were observed based on the treatment sequence.
Conclusions:
- The thermomechanical device (Buzzy) effectively reduced pain associated with IANB injections in pediatric dental patients.
- This finding supports the use of thermomechanical devices as an adjunct for pain management in pediatric dental anesthesia.

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.4K
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...

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
1.2K
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.

01:12Local Anesthetics: Adverse Effects
758
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:11Local Anesthetics: Clinical Application as Spinal Anesthesia
1.3K
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...

Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...
