Intracranial Pressure

The cranial vault contains brain tissue, blood and CSF--there is no room for anything else! If any of these components has a volume increase, there will be alteration in hemostasis. The pressure inside is 10-20 mmHg (normal ICP)-anything above 20 will compromise tissue perfusion.

Neuro Assessment

Frequent reassessments are essential to detect any changes in neurologic status. This in cludes:
*Cerebral Function
*Cranial Nerves
*Motor System
*Sensory System
*Reflexes

Glascow Coma Scale
Helps evaluate LOC. Scale evaluates Eyes, Motor and Verbal response. Use least invasive method to stimulate a response.
Changes in the level of consciousness is the most important and usually first indicator in deterioration of neurologic status.
Arousal is the lowest level of consciousness. It is imperative to protect the airway of a client with ALOC!

Nervous System

The nervous system is divided into the Central Nervous System and the Peripheral Nervous System.
Central Nervous System includes the brain and spinal cord.

Peripheral Nervous system includes nerves and the Autonomic Nervous System which consists of the Sympathetic Nervous System (fight or flight) and Parasympathetic Nervous System (rest and digest).

Hemodynamics

Normal bloodflow/conduction of the heart

Image found here.Image found here.

STROKE VOLUME is influenced by:
PRELOAD-degree of myocardial stretch just before systole
AFTERLOAD(aorta)-amount of resistance against which the left ventricle pumps
CONTRACTILITY-force fo the contraction

CARDIAC OUTPUT=SVxHR
Normal CO is 4-8 L/min

MAP (Mean Arterial Pressure)=Systolic pressure+2 diastolic pressures/3
MAP>60

CENTRAL VENOUS PRESSURE-Evaluates venous return and fluid volume status. Basically tells you your preload.
Normal CVP is 2-8 mmHg (same as JVD)

Cholelithiasis

Attacks commonly follow meals rich in fats or may occur at night. suddenly awakening the patient. They begin with acute abdominal pain in the right upper quadrant that may radiate to the back. between the shoulders. or to the front of the chest; the pain may be so severe that the patient seeks emergency department care. Other features may include recurring fat intolerance. biliary colic. belching. flatulence, indigestion. diaphoresis. nausea. vomiting. chills. low-grade fever. jaundice (if a stone obstructs the common bile duct). and clay-colored stools (with choledocholithiasis).

Clinical features of cholangitis include a rise in eosinophils, jaundice, abdominal pain. high fever. and chills; biliary drrhosis may produce jaundice, related itching, weakness, fatigue. slight weight loss. and abdominal pain. Gallstone ileus produces signs and symptoms of small bowel obstruction - nausea. vomiting, abdominal distention, and absent bowel sounds if the bowel is completely obstructed. Its most telling symptom is intermittent recurrence of colicky pain over several days. Each of these disorders produces its own set of complications.

*KNOW*GI Stimulants-Reglan-increases peristalsois. Good for post op. Parasympathetic NOT FOR PARKINSON's

Digestive Enzymes-for cystic fibrosis-help break down food. Need for ALL snacks. Big tablets. If fat is present in stool (stedorhea) pt may be non compliant or med not working. Do not chew meds.

Congestive Heart Failure (CHF)

Condition in which the pumping of the heart becomes impaired and is unable to meet the body's demands.

NEED A LOT OF REST. Pulse O2 is 93-95%

Etiology:
Diabetes

Tx:
Upright (High/Semi Fowler's)
Nitrate
Diuretics (Laxix)
O2

I&O is important! We want to get rid of fluid. Pts. with CHF are almost always on fluid restrictions. (WEIGHT IS MOST ACCURATE MEASUREMENT OF FLUID!!) Na+ restriction.

Left-Sided Failure: Blood backs up the left ventricle and atrium and into the pulmonary veins, increasing the pressure in the veins forcing blood into the lungs.

S/S:
*Dyspnea, orthopnea (Night-proxysmal nocturnal dyspnea)
*Cough
*Fatigue
*restlessness & anxiety

Decreased cardiac output, poor tissue perfusion leads to cardiac hypertrophy (gets larger)


Right Sided Failure:
*Primarily caused by left sided failure

S/S:
*Fluid and pressure in venous system
*Edema (pitting)
*Hepatomegaly
*Anorexia
*Nocturia
*Weakness
*Ascites
*Distended jugular veins

More of a systemic affect.

Diagnostic Studies:
*Echocardiogram
*Angiogram
*MUGA Scan-Evaluates heart size, ventricular wall motion, ejection fraction
*Blood Tests
*Chest X-Ray
*Labs--Electrolyte imbalances from diuretics
Watch for anemia

Assessment:
Changes in LOC, restlessness, confusion
Labored resepiration, adventitous sounds
JVD-distention?
Urinary output
Periph. cap refill, periph pulses

Antiplatelets

Prevent platelet adhesion-inhibit platelet aggregation. Very beneficial in the prevention of heart attacks, TIAs and strokes.

Acetylsalicylic Acid (ASA)-Aspirin

Contradictions:
*GI Bleeding
*Long term use can alter liver, renal and clotting function (GET LABS FIRST TO MONITOR!!)

Do not give on an empty stomach
Check bleeding tendencies

Adverse Effects:
*Salicylate Poisoning -->See slide
*GI bleeding
*Bronchoconstriction

Plavix

Anticoagulants

Prevent the formation of clots. Can be used prophylactically (preventatively).

ALWAYS LOOK AT LAB VALUES!

Coumadin (Warfarin)-used for continued treatment.
*Only oral anticoagulant
*Monitor-->Prothrombin time (PT) and International Normalized Ratio (INR)

-Well absorbed in the GI tract subcutaneously
-Does not cross placenta or breast milk
-Hypersensitivity and bleeding are contradictions
-CONTRADICTIONS with renal/hepatic, retinopathy, ulcers, spinal cord or brain injuries, pregnancy (don't want pt. to bleed out!!)
-Antecdote is Vitamin K

BLEEDING SIDE EFFECT
Watch for bleeding, petichiae
AVOID high Vitamin K foods! (They enhance clotting)
Injection is given in 5/8 in. 26-28 guage needle
May be used until oral therapy is adequate.

May be used with heparin until it is adequate alone.



Heparin-used for acute treatment.
*Sub Q or IV
*Monitor -->Partial Thromboplastin Time (PTT) OR Activated Partial Thromboplastin Time (APTT)

-Well absorbed in the GI tract subcutaneously
-Does not cross placenta or breast milk
-Hypersensitivity and bleeding are contradictions
-CONTRADICTIONS with renal/hepatic, retinopathy, ulcers, spinal cord or brain injuries, pregnancy (don't want pt. to bleed out!!)
-Antecdote is protaminie sulfate

BLEEDING SIDE EFFECT
Watch for bleeding, petichiae
AVOID high Vitamin K foods! (They enhance clotting)
Injection is given in 5/8 in. 26-28 guage needle
May be used until oral therapy is adequate.

DVT (Deep Vein Thrombosis)

Disorder involving a thrombus (blood clot) in a deep vein, most commonly the iliac and femoral veins.

Patho-Localized platelet aggregation and fibrin entrap RBCs, WBCs and more platelets to form a thrombus (frequently in the valve cusps of veins where venous stasis occurs). May lead to an emboli.

Assessment:


Subjective Data:
*Pain/Tenderness in calf or groin

Objective Data:
*Warmth
*Edema
*Extremities measurements
*+ Homan's -->controversial

Diagnosic Studies: Ultrasound, D-dimer, CT


Nursing Diagnosis:

Ineffective peripheral tissue perfusion

Goals:
*PREVENTION!!!
*Adequate blood flow to extremities
*No pulmonary embolism (PE)

Interventions:

*Affected leg circumference
*Doppler
*Bed Rest (Do NOT massage extremity)
*Elevate Leg
*Warm moist packs
*Compression stockings
*Anticoagulants - COUMADIN & HEPARIN
*DO NOT WALK ON LEG!!
*Monitor for S/S of PE (SOB, chest pain)

Patient Teaching:
*Need for frequent f/u with blood tests
*Side effects of drugs-blood in urine or stool, unusual bleeding, severe h/a or stomach pain, weakness, dizziness, change in LOC, cold blue or painful feet.
*Avoid trauma or injury that may cause bleeding
*Avoid NSAIDS and alcohol
*Avoid Vitamin K
*Contact EMS immediately if CP, SOB, palpitations or feeling of passing out is experienced.

Cardiac Assessment/Flow of the Heart

Preload-the volume of blood in the ventricles at the end of diastole.
Afterload-Resistance left ventricle must overcome to circulate blood.

SYSTOLE=contraction
DIASTOLE=relaxation

Cardiac Assessment:
Subjective Data:
*Past health Hx
*Medications (current and past)
*Sx and other Tx

Objective Data:
*V/S
-orthostatic/postural BPs and HRs should be monitored while pt. is lying, sitting and standing. Normally there is a reduction of up to 15 mm HG in the SBP and 3-5 mm HG in the DBP from the lying to standing position. HR should not increase more than 20 bpm from supine to standing position.
*Auscultation
-PMI/Apical pulse (Point of maximal impulse)-->when PMI is below the fifth ICS and left of the midclavicular line, the heart may be enlarged.
*Peripheral pulses

SEE p.749 for ABNORMALITIES!!

Terms:
Bruit-turbulent blood flow in an artery
Thrill-Vibration
Heaves-lifts (almost visualized pulses)/Pulsation

Pg. 740 Lewis
