The control of pain and choice of words are very important in the treatment of pediatric patients. The golden standard for lidocaine is 4.4 mg/kg with an absolute maximum of 300mg. Cowhorn mandibular forceps are contraindicated for primary teeth exodontia.

In Lido 2% 1:100,000 Epi = 36mg of Anesthestics. Know the Max dosage of LA used based on the Kg of Pedo pt.
Topical Anesthesia only works if used properly. Should place it over dried areas. Also it would work the best if leave it in for around 2 minutes.

Maximum local anesthetic dosage must be calculated for each pt before the procedure by pt. weight (4.4 mg lido/kg, 2.2 lbs/kg) & absolute maximum (300 mg lido) and converted into number of cartridges (36.4 mg/cartridge). Local anesthetic and needle should also be loaded beforehand.

The most important thing this lecture was definitely knowing the maximum amount of anesthetic to give a child. Know the child's weight in pounds, divide it by 2.2 to convert to kg, then multiply by 4.4mg/kg to get the maximum dosage in mg. Then divide by 36mg per carpule to get the number of carpules.

Make sure you know the pts. weight and figure out the absolute maximum amount of local anesthetic that can be used before the pt sits in the chair. Also, use blocks instead of infiltrations if you need to anesthetize a large area and think the max will be reached. Ex) infraorbital vs. infiltrations.

While in adults one can usually feel safe about giving up to 7 carpules of lido w/ epi, in children, one must take into account how many kilos the child weighs, and give no more than 4.4mg/kg, up to 300mg.

Know what anesthetic you are using. and when giving a description to young kids, keep explanations simple (ex: sleepy juice ). Do not give examples that may infer about pain and scare kids such as pinching, sting,..etc.

Anonymous said...

When a child is in pain, the child is unable to cooperate. It's better to use anesthetic to avoid pain and have their cooperation. When giving the anesthetic injection, don't lie to the child by saying that 'it won't hurt'. The child will lose trust in you and not believe you again. It's better if you tell them that 'it will feel weird'.

Prior to injecting any anesthetic in a pediatric patient, make sure that you are familiar with the maximum dose for the patient. For example, no more than 4.4mg lidocaine/kg weight with an absolute maximum dose of 300mg should ever be administered. IA injections in children are given slightly inferior and posterior to where you should inject on an adult.

The amount of anesthetic that is given to a pediatric patient should be calculated BEFORE treatment begins. The maximum is 4.4 mg/kg with a maximum of 300 mg total of 2% lidocaine with 1:100,000 epi. To calculate this, one needs to know that each carpule of lidocaine has 36 mg of lidocaine.
Also, it is probably better not to give topical anesthetic to really young children because it can go down their throats and make them gag or vomit.

Extraction of primary teeth takes planning ahead of time.
1) you must look at the position of both the primary and developing permanent tooth to make sure that the permanent tooth is not damaged in the proceedure
2) You must plan the dosage of local anesthesia to make sure you do not over medicate for the child's mass.
