What should be done by medical staff contained by the event of a lidocaine overdose?
Many cosmetic procedures are done under a local. How do you know when someone has had too much Lidocaine and what should be done when that happen?
Also, what role does Epinephrine play, or should it be used with Lidocaine
Answers:
Lidocaine toxicity is extremely rare -due to incentive usually being the dosage, esp. when being utilized by the hands of someone who know what they are doing.(please be you)
The mechanism in which Lido acts is the decrease effectiveness of the sodium ion channels coupled with neural blockade & sedation.
The kick-off of Lido toxicity is easily identified by a series of predictable symptoms:
lightheadedness, numbness of the tongue, visual disturbances, muscle twitching, unconsciousness, seizure, coma, respiratory arrest, and cardiovascular depression.
As the dose of Lido is increased, the probability the patient may endure CNS toxicity also presents itself. symptoms : poor concentration, dysarthria, metallic taste, sedation, headache, muscle twitches, etc.
NOW, IF Lido toxicity (overdose) is suspected, stop injection immed. prepare to the tolerant for treatment.
By intubation or by face mask, ensure adequate oxygenation to the long-suffering. If observed, seizures should be controlled by benzodiazepines and barbiturates (anticonvulsants). MONITOR CVS and administer intravenous fluids and vasopressors as needed.
The essential goal here would be to eliminate the neuromuscular and rational manifestations of seizures and to secure a exclusive rights airway.
Succinylcholine (muscle relaxant) is occasionally used (INTUBATION REQUIRED) to stop the neuromuscular eff. of seizures - the point being to facilitate airway control of the patient.
In vocabulary of barbiturates ( if needed ) Thiopental (Pentothal) would be the best choice here.
In terms of benzodiazepines: Diazepam (Valium) or Midazolam (Versed) would be the best choices here.
In reference to the drugs of choice listed, please consult an anesthesiologist next to knowledge of the patients medical history before you proceed. ( IMPORTANT )
Epinephrine is commonly combined with Lido for several reason:
It decreases bleeding at injection site, improves spinal blockade, serves as a "marker", AND *MI* prolongs the action of the local anesthetic (epinephrine act as a vasocontrictor, so the veins will decrease their diameter and reduce blood flow at the injection site, allowing Lidocaine to remain at the site for a longer time.)
This BARELY TOUCHES upon lidocaine and its toxicity, PLEASE research and backup these concept on your own, and as always PLZPLZPLZ BE CAREFUL. =]
If the incident occurs contained by a private office, not much will be done. But if it occurs in a hospital or out-patient surgical facility certified by the Joint Commission, the facility is required to follow its set of by-laws, rules and regulations. If the complaint is directed to the medical staff, the medical staff by-laws will pertain. In one of the community hospitals where on earth I practiced and served on the executive committee, such a complaint would be brought to the patient care committee. Usually the offending doctor would have to appear back the committee and explain his actions. If the physician's attorney were involved, the committee would arrange for expert testimony. If the physician be found to be at fault, several options could result: 1) he or she could be temporarily or permanently suspended, depending on bygone history of bad practice, 2) could have admitting privileges reduced to prohibit sure procedures, and/or 3) could be required to take pertinent CME courses.
Epinephrine constricts the small blood vessels in the nouns where the lidocaine is injected, prolonging the lidocaine's effect. Excessive amounts can cause cardiac arrhythmia and other undesirable stuff.
The thing you tend to notice almost lidocaine overdoses is that the patient's having a seizure. As with other seizure, the main thing to do is make sure the lenient doesn't flop down on the floor or into furniture, so protection from injury (for instance, moving furniture out of the way) is first on the list, and that's usually all that's needed.
Epinephrine slows the release of lidocaine from the soft tissues into the bloodstream, so it allows a larger amount to be used safely, along near the other advantages. That's why lidocaine with epinephrine in a pre-mixed combination is so popular.
