Study Notes
Chest Tube Management
- Chest Tube Precautions: Do not milk or strip the tubing as this can cause damage to the pleural tissues.
- Patient Assessment: Monitor vital signs, respiratory rate and pattern, oxygen saturation, and assess for signs of respiratory distress.
- Subcutaneous Emphysema: Check for a crackling sensation under the skin during palpation.
- Promote Lung Expansion: Encourage deep breathing and coughing exercises, and the use of an incentive spirometer.
- Facilitate Mobility: Assist with ambulation to prevent complications like atelectasis and pneumonia.
- Pain management: Administer analgesics as prescribed to ensure patient comfort.
- Monitor Drainage: Regularly assess drainage amount, color, and consistency, reporting any concerning changes to the physician.
- Chest tube removal: Apply an occlusive petroleum gauze dressing over the site to prevent air from entering the pleural space.
Chest Tube Complications and Emergency Management
- Dislodged Chest tube: Instruct the patient to perform the Valsalva maneuver, apply a Vaseline gauze followed by a dry sterile gauze over the site, and notify the physician immediately.
- Disconnected Chest Tube: Submerge the tube 2-4 cm below the surface of a bottle of sterile water or saline to create a temporary water seal. Cleanse the end of the patient connector with alcohol if uncontaminated. Replace the entire chest drainage system if contaminated.
Nursing Diagnoses
- Possible Nursing Diagnoses: Ineffective airway clearance, impaired gas exchange, activity intolerance, anxiety, death anxiety, ineffective health management, imbalanced nutrition: less than body requirements, powerlessness, self-care deficit.
Blood Flow Disruption in Acute Coronary Syndrome (ACS)
- Atherosclerosis: Build-up of plaque within coronary arteries, narrowing the passage for blood flow.
- Plaque Disruption: Rupture or erosion of atherosclerotic plaque triggers thrombus (blood clot) formation and potential vasoconstriction, abruptly reducing blood flow to the heart muscle.
- Myocardial Ischemia: Reduced blood flow deprives the heart muscle of oxygen, leading to ischemia, manifesting as chest pain (angina) or myocardial infarction (heart attack).
Importance of Blood Flow Restoration in ACS
- Preservation of Myocardium: Primary goal of ACS management is to restore blood flow as quickly as possible.
- Symptom Relief: Restoring blood flow alleviates pain associated with ischemia.
- Prevention of Complications: Prompt restoration of blood flow reduces the risk of complications such as arrhythmias, heart failure, and cardiogenic shock.
Interventions to Restore Blood Flow in ACS
- Emergent Percutaneous Coronary Intervention (PCI): Used for ST-segment elevation myocardial infarction (STEMI) to open the blocked artery and a stent to keep it open.
- Fibrinolytic Therapy: Administering medications to dissolve the clot blocking the artery, used when PCI is not readily available, for STEMI.
- Coronary Artery Bypass Grafting (CABG): Surgical procedure creating a detour around blocked arteries using grafts to restore blood flow to the heart muscle.
- Nitroglycerin: Dilates coronary arteries, improving blood flow and reducing myocardial oxygen demand.
- Intra-Aortic Balloon Pump (IABP): Improves coronary blood flow during diastole and reduces the heart's workload.
Blood Flow Assessment
- Cardiac Output (CO): Indicates the volume of blood pumped by the heart per minute, reflecting its overall efficiency.
- Mean Arterial Pressure (MAP): Represents the average pressure in the arteries, providing a more accurate picture of organ perfusion.
- Electrocardiogram (ECG): Helps identify areas of ischemia or infarction based on electrical activity changes in the heart.
- Cardiac Markers: Elevated levels of cardiac enzymes, such as troponin, indicate heart muscle damage, suggesting impaired blood flow.
- Clinical Presentation: Assessing symptoms like chest pain, shortness of breath, dizziness, nausea, and diaphoresis helps gauge the severity of ischemia and blood flow disruption.
- Key Message: Prompt recognition and intervention are crucial in ACS to restore blood flow and prevent irreversible damage.
Blood Flow in the Context of Acute Coronary Syndrome
- Key Focus: Disrupted blood flow is a key factor contributing to ACS.
- Intervention Goal: Restore adequate blood flow.
- Stress and ACS Relationship: Stress management techniques for patients at risk of CAD suggest that chronic stress can indirectly contribute to heart disease.
- Patient Case Studies: Illustrate the interplay of multiple risk factors in managing chronic conditions and highlight addressing modifiable risk factors.
Burn Management Phases
- Three Phases: Emergent (resuscitative), acute, and rehabilitation.
Emergent Phase (Resuscitative)
- Timeframe: From the onset of the burn up to 5 days, typically averaging 72 hours.
- Focus: Stabilization of the patient's condition and prevention of life-threatening complications.
- Airway Management: Assessing for signs like stridor, facial burns, soot and edema to determine the need for intubation and mechanical ventilation.
- Breathing Support: Evaluating ventilation adequacy through respiratory rate, depth, lung sounds, and oxygen saturation. Interventions might include oxygen therapy and ventilatory support.
- Circulation Preservation: Checking pulses, blood pressure, capillary refill, skin color, and temperature. Prompt fluid resuscitation is critical for burns over 15% TBSA.
- Disability Evaluation: Using the AVPU scale (Alert, Verbal, Pain stimuli, Unresponsive) to assess the patient's level of consciousness.
- Exposure and Environmental Control: Removing non-adherent clothing and jewelry and covering the patient with a sterile sheet to protect the burn wound and prevent hypothermia.
- Pain Management: Effective pain relief through intravenous opioids is essential for patient comfort.
- Fluid Resuscitation: Crucial for burns exceeding 15% TBSA. Formulas like the Parkland formula guide fluid administration. The goal is to maintain adequate urine output.
