Study Notes

Enabling Learning Objective

Aim: Perform safe and effective nursing care for patients with acute coronary syndrome.
Scenario: Address an acute myocardial infarction (AMI) without causing further harm.

Treatment Goals for Acute Myocardial Infarction

Establish reperfusion to restore blood flow.
Reduce infarct size to limit tissue damage.
Prevent and treat complications to enhance recovery.
Provide emotional support and education for patients and families.

Medical Treatment Strategies

Pain Relief: Administer morphine sulfate IV for immediate relief.
Oxygenation: Ensure adequate oxygen supply to the myocardium.
Platelet Aggregation Prevention: Use medications to reduce clotting risks.
Thrombolytic Therapy: Employ thrombolytics or interventional therapy to restore blood flow.

Early Therapy Protocol (MONA)

Implement a protocol involving IV-line, oxygen, aspirin, nitroglycerin (NTG), and morphine for chest pain suggestive of serious illness.

Pain Management During AMI

Morphine is the drug of choice for pain relief; it binds to CNS opioid receptors to inhibit pain pathways.
Includes side effects such as hypotension, respiratory depression, and sedation.
Titrate morphine dose carefully; monitor vital signs and level of consciousness.

Nitrates in AMI Management

Nitrates reduce ischemic pain and increase coronary perfusion through vasodilation.
Common side effects include headache, dizziness, and hypotension.
Important to monitor blood pressure; avoid administration if <90/60 mmHg.

Preventing Platelet Aggregation

Administer aspirin (325 mg) immediately for suspected acute coronary syndrome (ACS).
Platelet inhibitors, such as clopidogrel and prasugrel, prevent clotting events.
Side effects may include bleeding and gastrointestinal discomfort.

Nursing Implications for Anticoagulation

Assess for concurrent medications, herbal supplements, or over-the-counter drugs that might increase bleeding risk.
Educate patients on the importance of adhering to prescribed therapies and recognizing signs of bleeding.

Restoration of Blood Flow with Fibrinolytics

Fibrinolytics (clot busters) are crucial within 12 hours of symptom onset, ideally within 1-2 hours.
Examples include alteplase, reteplase, and tenecteplase; they work by dissolving occlusive clots.
Key risks include internal bleeding, especially in hypertensive patients.

Nursing Considerations for Fibrinolytics

Conduct rapid evaluations to determine patient candidacy for thrombolytic therapy.
Monitor vital signs diligently for signs of allergic reactions or hemorrhage.
Educate patients on the purpose, risks, benefits, and symptoms to report following therapy.

Key Questions and Answers

Oxygen Deprivation Consequences: Oxygen deprivation can lead to tissue death.
Opioid Overdose Reversal: Use naloxone (Narcan) to reverse effects of morphine overdose.
Nitrate Considerations: Monitor blood pressure; do not administer if <90/60 mmHg.
Patient Education: Emphasize the importance of recognizing bleeding symptoms while on platelet inhibitors.

General Summary

This section focused on the comprehensive management and nursing implications for patients experiencing acute myocardial infarction, highlighting critical treatment protocols, pharmacological interventions, and necessary patient education.
