Q

Tenecteplase MOA

A

Tenecteplase accelerates the breakdown of clots by stimulating TPA (tissue plasminogen activator, an enzyme) to facilitate the increased conversion of plasminogen to plasmin, resulting in a breakdown of fibrin ( the mesh casing of vessels).

Known to be pregnant or less than two weeks postpartum.
Time of onset of symptoms was greater than 12 hours ago.
Dependent on others for activities of daily living.
Another disease significantly shortens their life expectancy.
Very frail.
Suspected aortic dissection.
Major surgery, major trauma or severe brain injury within the last six weeks.
Intracranial surgery within the last six months.
Ischaemic stroke within the last six months.
Previous intracerebral haemorrhage.

Q

administration of tenectplase

A

Follow weight based medication chart
Dissolve the powder using the syringe within the kit.
Carefully discard unwanted drug from the syringe, preferably into the ampoule before administration, ensuring the correct dose remains in the syringe.
If an error is made in discarding unwanted drug and the correct dose cannot be drawn up, administer the remaining drug, document this well, and notify the receiving clinician.

Administer undiluted as an IV bolus, preferably into a running IV line.

Q

advese effects of tenectaplase

A

Bleeding. Tenecteplase commonly causes superficial bleeding, including epistaxis, bruising and bleeding from IV sites.
Dysrhythmia. It is common for dysrhythmia to occur if the coronary artery reperfuses. Most commonly the rhythm is accelerated idioventricular rhythm (AIVR) which does not require specific treatment. Other dysrhythmias should be treated using the appropriate section.

Q

enoxaparin preparation

A

Pre-filled syringe containing 100 mg in 1 ml.

18
Q

what is enoxaparin

A

low molecular weight heparin (LMWH) anticoagulant.

19
Q

enoxaparin mechanism

A

Enoxaparin increases the activity of antithrombin lll (a naturally occurring anticoagulant, inhibits clotting ) causing inhibition of multiple coagulation factors including clotting factor II (thrombin) and factor 10 Xa (which makes fibrin). thrombin is unable to convert fibrinogen to fibrin and form a clot.

20
Q

ILS enoxaparin indication

A

STEMI in conjunction with fibrinolytic therapy.

21
Q

contraindction of enoxaparin

A

allergy

22
Q

cautions of enoxaparin

A

Clinically significant bleeding. Enoxaparin will increase bleeding.
At risk of bleeding. If there are any cautions present within the fibrinolytic therapy checklist, personnel must seek clinical advice or discuss with the STEMI coordinator prior to administration.
Pregnancy.

23
Q

admin of eneoxaparin

A

Administer subcutaneously into the abdominal wall.
There is no need to sterilise the skin at the site of injection unless the skin is visibly contaminated.
Discard unwanted drug from the syringe before administration.
If an error is made in discarding unwanted drug volume and the dose remaining in the syringe is less than planned, administer the remaining dose.

24
Q

adverse effects of eneoxparin

A

increased bleeding
