What is the management protocol for a patient requiring advanced life support?

Advanced Life Support Management Protocol

Advanced Life Support (ALS) requires a systematic approach following established algorithms for cardiac arrest, focusing on high-quality CPR, early defibrillation, airway management, medication administration, and post-resuscitation care to optimize survival and neurological outcomes.

Initial Assessment and Immediate Actions

• Verify scene safety
• Check responsiveness
• Activate emergency response system
• Look for no breathing or only gasping and check pulse simultaneously (within 10 seconds) 1

For Cardiac Arrest (No Pulse):

1. Start high-quality CPR immediately:

   • Push hard (at least 2-2.5 inches/5 cm of chest depth)
   • Push fast (100-120 compressions/minute)
   • Allow complete chest recoil
   • Minimize interruptions in compressions 1

2. Apply cardiac monitor/defibrillator as soon as available

   • Check rhythm
   • If shockable rhythm (VF/pVT): Deliver 1 shock, then immediately resume CPR for 2 minutes
   • If non-shockable rhythm (asystole/PEA): Continue CPR 1

Airway Management

• Establish advanced airway using endotracheal intubation or supraglottic airway device
• Confirm placement with waveform capnography or capnometry
• Once advanced airway is secured, provide 10 breaths/minute with continuous chest compressions 1
• For pediatric patients, consider cuffed endotracheal tubes (except in newborns) with cuff inflation pressure <20 cm H₂O 2

Medication Administration

1. Establish IV/IO access

2. For shockable rhythms (VF/pVT):

   • Epinephrine 1 mg IV/IO every 3-5 minutes
   • Amiodarone 300 mg IV/IO after third shock for refractory VF/pVT (or lidocaine if amiodarone unavailable) 1, 3

3. For non-shockable rhythms (asystole/PEA):

   • Epinephrine 1 mg IV/IO every 3-5 minutes
   • Atropine 3 mg IV once for asystole 1

4. For pediatric patients:

   • Epinephrine 0.01 mg/kg (0.1 mL/kg of 1:10,000 concentration) IV/IO every 3-5 minutes
   • Amiodarone 5 mg/kg IV/IO for refractory VF/pVT 1

Rhythm Check and Defibrillation

• Perform rhythm checks every 2 minutes
• Minimize interruptions in chest compressions to less than 10 seconds
• For persistent VF/VT:
  • Continue CPR
  • Deliver shocks at appropriate energy levels
  • Consider changing pad positions or using a different defibrillator 1

Reversible Causes (H's and T's)

• Actively search for and treat reversible causes:
  • Hypovolemia: Administer IV fluids
  • Hypoxia: Ensure adequate oxygenation
  • Hydrogen ion (acidosis): Consider sodium bicarbonate for prolonged arrest
  • Hypo/Hyperkalemia: Administer calcium, insulin/glucose, or other electrolyte therapy
  • Hypothermia: Active rewarming
  • Tension pneumothorax: Needle decompression
  • Tamponade: Pericardiocentesis
  • Toxins: Administer specific antidotes
  • Thrombosis (coronary or pulmonary): Consider fibrinolytics 4

Post-Resuscitation Care

If return of spontaneous circulation (ROSC) is achieved:

1. Optimize oxygenation and ventilation:

   • Avoid hypoxia and hyperoxia
   • Maintain PaCO₂ within normal physiological range 1

2. Hemodynamic management:

   • Maintain systolic BP >90 mmHg or MAP ≥80 mmHg
   • Consider vasopressors if needed (dopamine, vasopressin) 5, 6

3. Temperature management:

   • Select and maintain constant target temperature between 32°C and 36°C for at least 24 hours
   • Prevent and treat fever in persistently comatose adults 1

4. Neurological care:

   • Treat seizures if they occur
   • Avoid prognostication before 72 hours after ROSC 1

Special Considerations

• Pregnant patients: Consider perimortem cesarean delivery for women in cardiac arrest in the second half of pregnancy 1
• Opioid overdose: Administer naloxone for respiratory arrest associated with opioid toxicity 1
• Pediatric patients: Use age-appropriate equipment and medication dosing; perform cycles of 15 compressions to 2 breaths when two rescuers are present 1

Common Pitfalls to Avoid

• Interrupting chest compressions for prolonged periods
• Hyperventilation (excessive rate or volume)
• Delayed or inappropriate defibrillation
• Failure to consider and treat reversible causes
• Premature termination of resuscitation efforts (continue for at least 20-30 minutes) 1
• Inappropriate prognostication before 72 hours after ROSC 1

Remember that high-quality CPR with minimal interruptions is the foundation of successful resuscitation, and early defibrillation for shockable rhythms significantly improves survival outcomes 7.
