What is intraosseous anesthesia?
The intraosseous injection allows placement of a local anesthetic solution directly into the cancellous bone adjacent to the tooth to be anesthetized. There are two intraosseous systems that have been studied clinically—the Stabident® system (Fairfax Dental Inc., Miami, FL) and the X-tip® system (Dentsply, York, PA).

What happens if you swallow local Anaesthetic?
Ingestion of lidocaine can cause numbness of the mouth and throat, which can lead to trouble swallowing and even choking. If a substantial amount is ingested, enough can be absorbed into the bloodstream to affect vital organs, primarily the brain and heart.
What injection do you inject into dental bone?
Your dentist might need to apply dental local anesthesia to numb an area of your mouth while performing certain procedures. We do this by injecting medicine – known as a local anesthetic – into your inner cheek or gum. Nowadays, the most common anesthetic dentists use is Lidocaine.
Is intraosseous infusion painful?
7 Extreme Pain: Although IO insertion looks painful, when inserted with a drill device, it is reported to be no more painful than an insertion of an 18g IV cathlon. There have been reports of increased pain with high-pressure infusions in conscious patients related to stimulation of pressure sensors within the bone.
Where is the anesthetic solution deposited during an intraosseous injection?
The intraosseous injection allows placement of a local anesthetic solution directly into the cancellous bone adjacent to the tooth to be anesthetized.
What happens if a dental injection hits a nerve?
Some of the signs of nerve damage after receiving a dental injection may include: A lack of sensation in the area treated even after the anaesthetic should have worn off. Numbness or lack of feeling in the tongue, gums, cheeks, jaw or face. A pulling or tingly sensation in these areas.
Can dental anesthesia cause nerve damage?
Abstract. Prolonged and possibly permanent change in sensation due to nerve damage can occur after dental injections. Although the condition is rare, many practitioners will see this form of nerve injury during their careers.
What is the antidote for anesthesia?
Oxygen: The Antidote for Systemic Toxic Reactions from Local Anesthetic Drugs.
What is anesthetic toxicity?
Abstract. Local anesthetic systemic toxicity (LAST) is a life-threatening adverse event that may occur after the administration of local anesthetic drugs through a variety of routes. Increasing use of local anesthetic techniques in various healthcare settings makes contemporary understanding of LAST highly relevant.
Can nurses insert intraosseous?
RN’s, physicians or EMT-P’s may insert an IO device after they have completed instruction with clinical supervision. An order must be received to by a physician for a RN or EMT-P to insert an IO.
How long does intraosseous last?
The intraosseous needle may remain in situ for 72 to 96 hours, but it is best removed within 6 to 12 hours, as soon as an alternative site of intravascular access has been established. The intraosseous route provides fast and reliable vascular access in emergency medical situations.
Why do we aspirate when giving local anesthetic?
Aspiration is recommended before the injection of local anesthetic to prevent accidental intravascular deposition and potentially generate undesirable local and/or systemic effects or complications.
How do you know if you hit a nerve when injecting?
Unlike some veins, nerves are not visible from outside the body, although you will definitely know if you’ve hit one while injecting because you’ll experience extreme pain and no blood will enter the syringe when you pull back to register. You may feel an electric “burn” along your limb.
How do I know if the dentist hit a nerve?

- Numbness or lack of feeling in the tongue, gums, cheeks, jaw or face.
- A tingling or pulling sensation in these areas.
- Pain or a burning feeling in these areas.
- Loss of ability to taste.
What happens if a dentist hit a nerve while injecting?
Nerve damage after a dental injection
This nerve damage could be minor, and the symptoms may disappear on their own after a few days or weeks. Alternatively, the nerve could potentially be damaged more seriously, which may mean long-term or even permanent symptoms.
What happens when you hit a nerve when giving an injection?
Other injection site events
If a nerve is hit, the patient will feel an immediate burning pain, which can result in paralysis or neuropathy that does not always resolve.
What is the earliest symptom of local anesthetic toxicity?
Initial signs and symptoms include agitation, confusion, dizziness, drowsiness, dysphoria, auditory changes, tinnitus, perioral numbness, metallic taste, and dysarthria. Without adequate recognition and treatment, these signs as symptoms can progress to seizures, respiratory arrest, and/or coma.
What is anaesthetic toxicity?
How painful is an IO line?
When can an IO not be used?
In a general manner, IO access should not be used in severe genetic or acquired bone diseases, imperfect osteogenesis, osteoporosis and osteomyelitis [17].
What are disadvantages of intraosseous route?
Known rare complications of IO access include extravasation, soft-tissue necrosis, bone fractures or injury to growth plates, infiltration of medications, infection, subcutaneous abscess, osteomyelitis, and embolic complications (fat emboli). Extravasation of fluid is the most common complication.
How painful is an IO?
Although the insertion of the IO needle itself is described as no more painful than an 18 gauge intravenous cannula, administration of IO fluids and medication can rapidly increase cavity pressure. This may become uncomfortable or painful and can restrict attempts at providing effective resuscitation.
What happens if local anesthetic is injected into a vein?
High dose or accidental intravascular injection of local anesthetic agent with vasoconstrictor may result in cardiovascular and central nervous system toxicity, as well as tachycardia and hypertension. Primary sings and symptoms of overdose are hypertension, tachycardia, tachypenia, headache, and vertigo.
What happens if you inject local anaesthetic into a nerve?
Exposure of peripheral nerves to local anesthetics may result in axonal damage, particularly if the solution is injected intrafascicularly, if the concentration is high, and if duration of exposure is prolonged.
