Special Care Tutorials Flashcards
1

9
Q
potential medical reasons for inability to achieve haemostasis
A
- bleeding disorders - haemophilia A and B, von willibrands disease
- antiplatelet meds

- infections - HIV, hep C
- liver disease - alcoholic liver disease, liver cirrhosis, herp B or C infection, hepatocellular carcinoma
10
Q
impaired liver function has an impact on
A
- hepatis synthesis of clotting factors and proteins involved in fibrinolytic system
- including vitamin K dependant coagulation proteins - II, VII, IX, X
- thrombocytopenia and thrombocuthaemia can also be a feature of liver disease
- alcohol can also have direct effect to suppress bone marrow - impair production of cells
11
Q
renal disease has an impact on
A
- abnormalities in platelet funcction
- poorly understood
- may be defects in platelet adhesion, secretion and storage
- as a result uraemia - a buildup of toxins in your blood. It occurs when the kidneys stop filtering toxins out through your urine
12
Q
how would you manage pt with failure to achieve haemostasis
A
- apply pressure to socket - could use LA soaked gauze
- La around socket
- pack socket with oxidised cellulose or a collagen sponge - surgical mesh helps clotting as framework to allow clot to latch onto
- suture the surgical site
- re-evaluate MH
- if availbale consider tranexamic mouth wash - tranexamic acid works by stopping blood clots from being broken down, reducing unwanted bleeding
- cautery - burning
- bone wax
* if unable to arrest haemorrhage phone local oral orgery or maxfax department - A&E if there is no OMFS unit
13
Q
if patient asks specific medical questions

- if score >49 may interfere in how we provide any dental tx
15
Q
features of pt with high UKELD score
A
- jauncide
- clubbing
- spider naevi
- palmar erythema - palms of hands red
- leukonychia - white nails
- other signs of advancing liver disease - bleeding, oesophageal varices, ascites, peritonitis
- alcohol related - tremors, cognitive impairment
16

causes of liver disease
A
- infective - hepatitis viruses B, C and D, rarely A
- autoimmune - primary biliary cirrhosis
- alcohol related
- non-alcoholic fatty liver disease
- drug induced
- hepatocellular carcinoma
- haemochomatosis - iron levels build up
17
Q
stages of liver disease
A
- hepatitis - inflammation of liver which may or may not be reversible
- liver cirrhosis - irreversible liver necrosis and fibrosis

- articaine advantageous as only 5-10% processed in liver
- NSAIDs can increase bleeding risk and risk of hepatorenal syndrome
- paracetamol risk as can be hepatotoxic
- consultation with hepatology if in doubt
- consideration with antibiotics - amoxicillin should be safe, metranidazole dose may be altered, erythromycin contraindicated
- IV sedation with midazolam not appropriate

A
- any step whcih can be reasonably taken to prevent putting a disabled person at a disadvantage in comparison with a non-disabled person
- factors to determine reasonableness are - effectiveness of adjustment, how practical it is, cost, potential disruption, time effort and resources
23
Q
if pt unable to transfer to dentla chair what are feasible options to aid transfer
A
- hoist - can be used for non-weight bearing individuals
- reclining wheelchair - no need to transfer
- turn table or stand aid - promotes involvement of pt

2. prevention - OHI, Fluoride "delivering better oral health" useful
3. stabilisation - main areas you want to stabilise are caries, perio, pulpal or periapical and extractions of hopeless teeth with immediate gap replacement if needed
4. definitive/restorative - you’re looking to carry out any direct restorations which were previously stabilised with GIC, any indirect restorations like onlays or crowns and you’ll also treat any missing spaces with bridges, dentures or implants
5. maintenance - reinforcing oral hygiene instructions and diet advice, rep-prescribing fluoride toothpaste if necessary, re-checking BPE or redoing 6 point pocket charts if they were a perio patient, giving a scale and polish if they need it and taking updated bitewings according to the FGDP guidelines
