Term in Complication and management safety

An adverse event restricted to the site of injection or target tissue, such as a muscle, nerve, or local blood vessel

Local Complication

An adverse reaction affecting the entire body, primarily involving the Central Nervous System (CNS) or Cardiovascular System (CVS)

Systemic Complication

An additive (like epinephrine) that constricts blood vessels to prolong numbness and decrease bleeding

Vasoconstrictor

An extremely rare event primarily associated with "hubbing," sudden patient movement, or intentional bending of the needle

Needle Breakage

Persistent anesthesia or altered sensation beyond the expected duration

Paresthesia

A transient loss of motor function occurring when anesthetic is inadvertently deposited into the parotid gland

Facial Nerve Paralysis

Rare issues like double vision (diplopia) or vision impairment caused by anesthetic diffusion toward the eyes

Ocular Complications

A restricted jaw opening caused by a spasm of the masticatory muscles

Trismus

An effusion of blood into extravascular spaces resulting from nicking a blood vessel

Hematoma

Self

inflicted trauma, such as biting or chewing the lip or tongue, while the area is still numb

Discomfort caused by careless technique, dull needles, or the low pH of solutions containing vasoconstrictors

Pain and Burning on Injection

An extremely rare postinjection occurrence caused by needle contamination or injecting into an already infected area

Infection

Swelling that can be a sign of trauma, infection, or a potentially life

threatening allergic reaction

Epithelial desquamation or sterile abscesses caused by prolonged ischemia or prolonged topical anesthetic application

Sloughing of Tissues

Ulcerations, such as aphthous stomatitis or herpes simplex, that may develop roughly two days after an injection

Postanesthetic Intraoral Lesions

A reaction occurring when elevated blood levels of anesthetic reach target organs, producing an extension of the drug's normal pharmacological actions

Overdose (Toxic Reaction)

A hypersensitive state where clinical manifestations are produced by an exaggerated immune system response

Allergy (Hypersensitivity)

The most common undesirable reactions, triggered by the act of drug administration rather than the drug itself, such as fainting or hyperventilation

Psychogenic Reactions

Unpredictable, non

pharmacological responses thought to have an underlying genetic mechanism

Drawing back slightly on the syringe before injecting to ensure the needle tip is not inside a blood vessel

Aspiration Technique

A safe limit of anesthetic tailored to the patient's body weight

Maximum Recommended Dose (MRD)

The core universal management protocol standing for Position, Circulation, Airway, Breathing, and Definitive care

P

A temporary lack of blood flow to the brain caused by fear, anxiety, or seeing the needle

Vasovagal Syncope (Fainting)

A reaction occurring when epinephrine accidentally enters a blood vessel or the patient is hypersensitive to it

Epinephrine Reaction (Adrenaline Rush)

A dangerous overdose where too much anesthetic enters the bloodstream, affecting the CNS and heart

Local Anesthetic Systemic Toxicity (LAST)

A management position where the dental chair is laid flat and tilted so the patient's feet are higher than their head

Trendelenburg Position
