Pain and Anxiety Flashcards
Local anaesthesia
Anaesthesia= loss of all sensation
Sensory nerve supply Responds to things like temperature pain
Sensation felt by electrical impulses sensory neurons to the brain then information acts
Local anaesthesia block the electrical impulses so don’t reach the brain
Local anaesthesia drugs either 2.2ml 1.8ml
Anaesthesic-block electrical nerve transmissions
Sterile water-acts as solution
Buffering agent- PH neutral maintains the contents
Preservative-shelf life
Vasoconsitrutictor-prolong action not all Anaesthesia closing local blood vessels so not carried away into blood stream
Common Anaesthesia
Lidocaine- 2% lignocaine hydrochloride 1:80000adreline as a vasoconstrictor
Articaine-carticane 1:100000 adrenaline as a Vasco constrictor
Citanest-3%priolocaine hydrochloride octapresin vascocontricter
Mepivacaine-3%no vascoconstricter
Increase rate of heart beat Affects Hypertension hbp Cardiac arrest poor heart Hyperthyroidism overactive thyroid gland
Elderly patients
HRT hormone replacement therapy affects of menopause prevent bones thinning
Thyroxine drug under active thyroid high heart rate
Also with antidepressants
Can use citanest but not pregnancy as it can affect uterus muscles
Local anaesthesia equipment
Diagpham silver bit needle pierces
Aspirating technique is designed to avoid the injection into the blood vessels
The plug or jumps back and is released so blood flow into cartilage and correctly goes into nerve
Topical anaesthesia gel 5% lidocaine paste 20% benzocaine
Useful for scaling fitting of matrix bands and stimulation of gag
Techniques administration
Nerve blocka soft tissue and jaw bone need to be used for 1 quadrant
Inferior dental block
all lower teeth lingualGum half of tongue lower lip and incisors bucks gum
Only bucaal gum molars not
Mental nerve block- soft tissues buccaneering or labial affected
Posterior superior dental nerve block-nerve maxillary antrum both upper second third molars affected
Locals infiltration
Over apex of tooth
Needle insertion mucous membraine soak thru pores of bone anaesthesia the nerve supply
Only for nerve endings not nerve trunk
Upper teeth lower incisals only for gingivae
Intraligamentary injection
Infiltration or a nerve block to produce deeper Anastasia around a hyper sensitive tooth
1.8ml gun shaped ligmaject syringe
Nerve block fails cannot be used for gingival infection u less tooth to be extracted
Intraosseous injection
Between gum to teeth gingvae into spongy bone Short duration Doesn’t numb lip check or tongue Good for extractions Not used for infection on gums Directly into sponagy bone
Local anaesthesia for extractions
You should also numb surrounding periodontium as well as periodontal ligaments
UPPER TEETH
Local infiltration for label and buckle and palatal sides..by all injection anaesthesia the tooth and buffalo and labial side while palatial peridontium
2nd and 3rd molars=
Posterior superior dental block
LOWER TEETH
inferior dental block injection numbs up the lingual in a part as well end section is mental nerve
The bone in I scope region is thin so u can numb labia and lingual local infiltration rather then the block
Lower molars will need local bucal infiltration
Local anaesthesia for restorative treatments
Not needed over loaded unless gingvae areas are just so need removal for the procedure part
-if a cavity has been present and the gum grow over it
-A crown a crown lenghting technique or for denture good look
-crown lost but a been a growth gingiva over growth
Need it for good impressions
UPPER TEETH RESTORATIVE-
enough is local buccal or labial infiltration for 3and 2 molars posterior superior Dental block preferred
LOWER TEETH-
Lower incisors= labial infiltration
Inferior dental nerve block numb every tooth but mental block other than lower molars
Preparation for local anaesthesia
If end is broken use artery forceps Spencer Wells or mosquito forceps
Topical service Anastasia applied cotton wall
Cartilage stored use room temperature because cold ones cause pain
Sometimes for large surgical procedures the injection site might be dried and disinfected with iodine or chlorhexidine on a cotton wall for 15 seconds
Inoculation injury
I needle is a sort of cross infection no matter how small
A resheathed use so no stick injury like a holder
Stop working immediately so other people are not at risk of cross infection as well
The pierced area should be squeezed and run under warm water you want to encourage bleeding
The winded area should be clean with disinfectant soap tried and covered waterproof dressing
Senior team should be notified The patient’s history medical should be reviewed to see if the HIV positive
If necessary report to the occupational health advisor 0H a I hospital and They will give you advice
The contact details are stored in infection control policy documentation
The incident should also be recorded in the accident book low risk of serious infections or our RIDDOR report written and process followed
Patient advice of the local Anastasia
Sensation lost several hours 2 roughly
Do you not eat drink smoke we might burn and hurt yourself
Chewy foods should be avoided
When the Anastasia is wearing off you feel something like pins and needles which is called paraesthesia
Wait until that’s finished to start eating or drink
If you have a nerve block injection it might be tender on the tissues of your mouth
Intraligamentary cause soreness around gingeva
Contact surgery if anything
Anxiety control
Two main anxiety control
General anaesthesia only is hospital
Unconscious
Conscious sedation can be done in a dental clinic or community clinic the techniques
Oral sedation
Inhalation sedation
Intravenous sedation
A state of relaxation used for a long procedures restorative
Special-needs patients who are uncooperative can have the Maison mache general Anastasia all sedation technique on the hospital premises under endotracheal Anastasia in hospital with critical care
Patient state of mine acupuncture and Hypno ptosis
General Anastasia endotracheal anaesthesia
Endotracheal Anistasia mixture of gases that go directly into the lungs through nas preaches like tube
Floor nose nasopharyngeal
Then a special instrument called laryngoscope guided thru trachea
The oropharynx pack with gauze protect forgien body
No danger of obstruction
