ANGINA PECTORIS
Definition
Angina pectoris is a symptom characterized by discomfort in the chest. It is caused by inadequate blood
supply to the myocardium.
1.Stable Angina predictable and consistent pain; occurs in exertion; relieved by rest.
2. Unstable Angina symptom occur more frequently and last longer than stable angina. Pain threshold
is lower, pain may occur at rest
3.Variant Angina or Prinzmetals Angina-pain at rest with reversible ST-segment elevation;caused by
coronary artery vasospasm, it usually occurs when a person is at rest or sleep and not after physical
exertion or emotional stress. It is associated with acute myocardial infarction,severe cardiac arrhythmias
including ventricular tachycardia and fibrillation and sudden cardiac death
Pathophysiology
Myocardial ischemia is caused primarily by an inadequate blood supply or an increased demand for
oxygen. The symptoms of angina differs from myocardial infarction in that angina is relieved by
nitroglycerin and MI is not.
Risk factors
smoking hyperlipidemia
alcohol age (45 for male and 55 female)
obesity race
sedentary life stress
DM personality

-heaviness Circulatory status
-dull pain Hypotension
-may radiate to the neck,jaw,shoulder and inner aspect of the upper arms
Associated Nursing Diagnosis
Ineffective cardiac tissue perfusion secondary to coronary artery disease as evidenced by chest pain
Death anxiety
Deficient knowledge about underlying disease and methods for avoiding complications
Noncompliance,Ineffective therapeutic regimen
Nursing Interventions
Identify exact site of distress
Direct patient to stop all activities and sit or rest in bed in a semi-fowlers position if chest pain is
sensed
Administer nitroglycerin: 1 tab every 5-15 minutes x 3 doses, report to MD if no relief; can also be
given prior to an exhausting activity
Encourage deep breathing to induce relaxationMonitor length of time (if not relieved in 15 minutes, other problems should be considered)
Pharmacologic Therapy
Medicine
Nitroglycerine Beta adrenergic blockers Calcium channel blocker Antiplatelet agent
NITROGLYCERINE (Nitrostat, Nitrol, Nitrobid IV)
-A vasodilator ; mainstay for treatment of angina pectoris
-it decrease myocardial oxygen consumption thus decrease ischemia and relieves pain
BETA ADRENERGIC BLOCKERS ( propanol , metropol ,atenolol )
-it helps to decrease myocardial O2 consumption by blocking the -adrenergic sympathetic stimulation
to the heart HR, slow circulation of an impulse through the heart ,BP
Myocardial contractility control chest pain and delay onset of ischemia
Contraindicated(+) asthma
CALCIUM CHANNEL BLOCKERS (amlodipine,verapamil,diltiazem)
- have different effect
8/2/2019 Icu Reviewer
3/24
- Decrease SA node automaticity and AV node conductivity resulting in slower HR and decreasedheart muscle contraction.
- Relax the blood vessel causing a decreased BP and increase coronary artery perfusion- Dilates smooth muscle wall of coronary arterioles to increase myocardial O2 supply- Used by patient who cannot take and with side effect with beta blockers and nitrates- Prevent and treat vasospasm- Amlodipine ( NORVASC) and felodipine (PLENDIL) DOC for heart failure
ANTIPLATELET & ANTICOAGULANT ( aspirin,clopidogrel & ticlopidine ,heparin ,GPIIb / IIIa agent)
-To prevent platelet aggregation w/c impedes blood flow
-aspirin- prevent platelet activation and reduce incidence of MI an death from CAD.
-clopedogril & ticlopidine alternative for pt. with allergy on aspirin
-heparin-it prevent the formation of new blood clot , it decreased the occurrence of MI to
pt.with unstable angina.
-GPIIIb / IIIa agent (abciximab,tirofibam,eptifibatide)-for Pt.with unstable angina
It prevents the aggregation by blocking GPIIb/IIIa receptor on platelet to prevent adhesion offibrinogen and other factors to each other forming a clot.
MYOCARDIAL INFARCTION
causes of MI include coronary artery obstruction due to the progressive development of
atherosclerosis; coronary artery spasm; embolism.
Assessment
Chest pain (described as substernal, crushing with radiation to the arm, neck, jaw, or back;pain is unrelieved by nitroglycerine) Dyspnea
Changes in heart area Nausea Vomiting Fever (up to 101F over the first 24 to 48 hours) Increased WBC count and sedimentation rate
Diagnostic test
Echocardiogram use to evaluate ventricular function
-detect hyperkinetic and akinetic wall motion and determine ejection fraction.
-12-lead ECG may show ST elevation as the MI is evolving or Q waves when the MI iscomplete.
Laboratory test
-After the onset of MI, enzyme elevation occurs as follows:
Serum glutamicoxaloacetic transaminase (SGOT) peaks in 24 to 48 hours.(AST)

CEREBROVASCULAR ACCIDENT
-It is an infarction that occurs in the brain. It is usually caused by a thrombus,embolism or haemorrhage
Pathophysiology
-It occurs when a local area of the brain is deprived of blood. Local or general disorders may cause the
alteration of the blood supply. If cerebral circulation is interrupted extensively,cerebral anoxia or lack of
oxygen to the brain develops.After 10 minutes changes to the brain resulting from cerebral anoxia are
irreversible.

GLASGOW COMA SCALE
Glasgow Coma Scale or GCS is a neurological scale that aims to give a reliable, objective way of
recording the conscious state of a person for initial as well as subsequent assessment.
GCS was initially used to assess level of consciousness after head injury, and the scale is now used by
first aid, EMS, and doctors as being applicable to all acute medical and trauma patients. In hospitals it is
also used in monitoring chronic patients in intensive care.

The scale comprises three tests: eye, verbal and motor responses. The three values separately as well as
their sum are considered. The lowest possible GCS (the sum) is 3 (deep coma or death), while the
highest is 15 (fully awake person).
Best eye response (E)
There are 4 grades starting with the most severe:
1. No eye opening2. Eye opening in response to pain. (Patient responds to pressure on the patientsfingernail bed; if
this does not elicit a response, supraorbital and sternal pressure or rub may be used.)
3. Eye opening to speech. (Not to be confused with an awaking of a sleeping person; such patientsreceive a score of 4, not 3.)
4. Eyes opening spontaneouslyBest verbal response (V)
There are 5 grades starting with the most severe:
1. No verbal response2. Incomprehensible sounds. (Moaning but no words.)3. Inappropriate words. (Random or exclamatory articulated speech, but no conversational
exchange)
4. Confused. (The patient responds to questions coherently but there is some disorientation andconfusion.)
5. Oriented. (Patient responds coherently and appropriately to questions such as the patientsname and age, where they are and why, the year, month, etc.)
Best motor response (M)
There are 6 grades starting with the most severe:
1. No motor response2. Extension to pain (abduction of arm, internal rotation of shoulder, pronation of forearm,
extension of wrist,decerebrate response)
3. Abnormal flexion to pain (adduction of arm, internal rotation of shoulder, pronation of forearm,flexion of wrist,decorticate response)
4. Flexion/Withdrawal to pain (flexion of elbow, supination of forearm, flexion of wrist whensupra-orbital pressure applied ; pulls part of body away when nailbed pinched)
5. Localizes to pain. (Purposeful movements towards painful stimuli; e.g., hand crosses mid-lineand gets above clavicle when supra-orbital pressure applied.)6. Obeys commands. (The patient does simple things as asked.)
Interpretation
Individual elements as well as the sum of the score are important. Hence, the score is expressed in the
form "GCS 9 = E2 V4 M3 at 07:35".

ENDOTRACHEAL SUCTIONING
Endotracheal Suctioning involves the insertion of a catheter into the clients artificial tracheal airway.
Endotracheal Suctioning maintains airway patency, facilitates removal of airway secretions, and
stimulates a deep cough. In the acute health care environment, tracheal suctioning is a sterile process.
In the home setting, the client may be instructed to use a clean suction technique as long as there
are no signs of infection
Purpose:
To maintain a patent airway and prevent airway obstruction
To promote respiratory functions (optimal exchange of oxygen and carbon dioxide into and out ofthe lungs)
To prevent pneumonia that may result from accumulated secretions
Assessment:
Observe for signs and symptoms of lower airway obstruction Secretions in airway, wheezes or crackles on inspiration and/or expiration Ineffective cough Unilateral or Bilateral absence or diminished breath sound Tachypnea Acutely shallow respiration Tachycardia or bradycardia Hypertension or hypotension Cyanosis Decreased level of consciousness
Planning:
Prepare patient Explain procedure and patients participation. Explain importance of coughing during procedure. Assist patient to assume comfortable position for nurse and client, usually semi-fowlers
of Fowlers. If unconscious, place in side-lying position.
Place towel across patients chestImplementation
1.Wash hands and turn suction device set on and set vacuum regulator to appropriate negative
pressure. Wear mask.
2. If using sterile suction kitA. Open package. If sterile drape is available, place it across patients chest
B. Open suction catheter package. Do not allow suction catheter to touch any unsterile surface
C. Unwrap or open sterile basin and place on bedside table. Be careful not t touch inside basin.
Fill with about 100 ml sterile normal saline
3. If indicated, open lubricant and squeeze on sterile catheter package without touching package.

4. Apply one sterile glove to each hand or apply non sterile to non-dominant hand and sterile glove to
dominant hand.
5. Pick up suction catheter with dominant hand without touching non-sterile surfaces. Pick up
connecting tubing with non-dominant hand.
6. Check the equipment if functioning properly by suctioning small amount of saline from basin
7. Coat distal portion 6-8 cm of catheter with water-soluble lubricant. In some situations, catheter is
lubricated only with normal saline. Nursing assessment indicates needs for lubrication
8. Remove oxygen or humidify delivery device with dominant hand
9. Hyperinflate and/or oxygenate client before suctioning, using manual resuscitation bag or sigh
mechanism on mechanical ventilator
10. Without applying suction, gently but quickly insert catheter with dominant thumb and forefinger
into artificial airway (best to time catheter insertion with inspiration).
11. Insert catheter until resistance is met, then pull back 1 cm.
12. Apply intermittent suction by placing and releasing non- dominant hand thumb over vent of catheter
while rotating back and forth between dominant thumb and forefinger. Encourage patient to cough.
13. Replace oxygen delivery device. Encourage patient to deep breath.
14. Rinse catheter and connecting tubing with normal saline until clear. Use continuous suction.
15. Repeat steps 10-14 as needed to clear secretions. Allow adequate time (at least 1 full minute)between suction passes for ventilation and reoxygenation.
16. Assess patients cardiopulmunary status between suction passes.
17. When artificial and tracheobronchial trees are sufficiently cleared of secretions, perform nasal and
oral pharyngeal suction are performed. When catheter is contaminated, do not reinsert into ET or TT.
18. Disconnect catheter from connecting tubing.
19. Remove towel and place in laundry, or remove drape and discard in appropriate receptacle.
20. Reposition patient.
21. Discard remainder of normal saline into appropriate receptacle. If basin is disposable, discard into
appropriate receptacle. If basin is reusable, place it in soiled utility room.
21. Wash hands and place unopened suction kit on suction machine or at head of bed.
