EMS Airway Management - iGel Supraglottic Airway Device

The iGel supraglottic airway device is an essential tool for EMS providers when managing a patient's airway, especially in situations where endotracheal intubation may be difficult or not immediately feasible.

Here’s some thing EMS providers need to know about the iGel:

1. Indications and Contraindications

- Indications: Emergency airway management in unconscious patients with absent or inadequate respiratory effort.

• Alternative to endotracheal intubation during cardiac arrest, respiratory arrest, or when intubation is not possible.
• Can be used in prehospital settings in combination with anesthesia, sedation, or other airway management situations requiring a secure airway.

- Contraindications:Conscious or semi-conscious patients with intact gag reflex.

• Patients with known esophageal disease or pathology, such as esophageal varices.
• Patients with a high risk of aspiration or who have ingested a large meal recently.
• Severe airway trauma or obstruction that may prevent insertion.

2. Device Design and Features

• Supraglottic Airway: The iGel is designed to sit above the glottis, creating a seal around the laryngeal inlet without inflating a cuff.
• Gel-Like Cuff: The cuff is made of a soft, gel-like material that molds to the patient’s anatomy, minimizing trauma and reducing the need for precise sizing.
• Integral Bite Block: Built-in bite block helps prevent the patient from biting down and occluding the airway.
• Gastric Channel: The device includes a gastric channel that allows for the insertion of a gastric tube to decompress the stomach and reduce the risk of aspiration.
• Sizing: The iGel comes in multiple sizes, typically based on patient weight, ranging from neonates to large adults.

3. Preparation and Insertion

• Sizing: Select the appropriate size based on the patient’s weight.
• Typical Ranges:
• Size 1: Neonates (2-5 kg)
• Size 2: Pediatric (10-25 kg)
• Size 3: Small adult (30-60 kg)
• Size 4: Medium adult (50-90 kg)
• Size 5: Large adult (90+ kg)
• Lubrication:Cover the back, sides, and cuff of the device with a water-based lubricant.
• Avoid over-lubricating the front of the device to prevent blocking the airway opening.
• Insertion Technique: Position the patient’s head in a neutral or slightly extended position.
• Open the patient’s mouth and gently insert the iGel along the natural curve of the airway until resistance is felt, indicating it is seated correctly.
• Avoid excessive force during insertion to prevent trauma.
• Confirmation: Confirm placement by observing chest rise, listening for bilateral breath sounds, and using capnography (if available).
• Security: Secure the device with a strap or tape to prevent dislodgement.

4. Maintenance and Monitoring

• Ongoing Assessment: Continuously monitor for effective ventilation, chest rise, and oxygen saturation.
• Regularly check for signs of dislodgement, obstruction, or leakage.
• Gastric Decompression: If necessary, insert a gastric tube through the gastric channel to decompress the stomach and reduce the risk of regurgitation and aspiration.
• Ventilation: Connect the device to a bag-valve mask (BVM) or ventilator, ensuring adequate tidal volume and oxygen delivery.

5. Complications and Troubleshooting

• Airway Obstruction: If ventilation is inadequate, reassess the device placement, and consider repositioning or reinsertion.
• Aspiration Risk: Despite the gastric channel, there is still a potential risk of aspiration; be prepared to manage this complication if it occurs.
• Device Dislodgement: Regularly check the device's position and secure it properly to avoid dislodgement, especially during patient movement or transport.
• Trauma or Discomfort: Monitor for signs of airway trauma or discomfort, particularly if insertion was difficult.

6. Removal

• Timing: The iGel should be removed once the patient regains consciousness and airway reflexes, or if endotracheal intubation is indicated.
• Technique: Gently withdraw the device while monitoring for any signs of obstruction, aspiration, or respiratory distress.
• Prepare to manage the airway immediately if complications arise during removal.

7. Training and Proficiency

• Simulation Training: Regular practice with the iGel device in simulated scenarios to maintain proficiency in its use.
• Familiarization: EMS providers should be familiar with the different sizes and specific features of the iGel, including the gastric channel and the appropriate insertion technique.
• Continuing Education: Stay updated on best practices, new developments, and guidelines related to supraglottic airway management.

8. Legal and Ethical Considerations

• Scope of Practice: Ensure the use of the iGel is within the provider’s scope of practice as defined by their certification level and local protocols.
• Informed Consent: While typically used in emergencies where consent cannot be obtained, providers should be aware of the ethical considerations in airway management.
• Documentation: Document the size of the device used, time of insertion, confirmation methods, patient response, and any complications encountered.

Conclusion

The iGel supraglottic airway device is a valuable tool in the EMS provider’s airway management arsenal. Proper selection, insertion, and management are crucial to ensure effective ventilation and patient safety. 

It was invented by Dr. Muhammed Aslam Nasir and is manufactured by Intersurgical.

Continuous training and familiarity with the device will enhance the provider's ability to use the iGel effectively in emergency situations.

EMS Medication Administration - RSI Endotracheal Intubation

EMS Providers should have a comprehensive understanding of rapid sequence endotracheal intubation (RSI) medication administration to ensure successful and safe management of patients requiring advanced airway interventions.

Here are some points they should know:

1. Indications and Goals

Indications:

• To facilitate endotracheal intubation (ETI) in patients who require definitive airway management.
• Medications administered during intubation typically include induction agents (sedatives) and neuromuscular blocking agents (paralytics) and analgesics (pain relievers).

Goals:

• Achieve rapid sedation and paralysis to facilitate smooth intubation without causing harm or distress to the patient.
• Ensure patient comfort and safety throughout the procedure.

2. Medications Used

Analgesic Agents:

• Fentanyl: EMS Providers should consider opioid administration to intubated patients, as NMBAs and sedatives do not relieve the pain associated with intubation and positive pressure ventilation (Fatolitis, 2022).

Induction Agents:

• Etomidate: Rapid onset sedative with minimal cardiovascular effects.
• Propofol: Potent sedative with rapid onset and short duration of action.
• Ketamine: Dissociative agent providing sedation, analgesia, and amnesia.
• Midazolam: Benzodiazepine used for sedation, less commonly for induction due to slower onset.

Neuromuscular Blocking Agents (NMBAs):

• Succinylcholine: Depolarizing agent for rapid paralysis.
• Rocuronium / Vecuronium: Non-depolarizing agent with longer duration of action and less side effects compared to succinylcholine.

3. Preparation and Technique

Medication Preparation:

• Verify the “Six Rights” of medication administration: right patient, right medication, right dose, right route, right time and right documentation.
• Calculate and prepare appropriate doses based on patient weight and condition.

Procedure Preparation:

• Ensure all equipment for intubation is ready and functional (e.g., laryngoscope, endotracheal tube, suction).
• Confirm patient positioning, secure environment, and adequate personnel for assistance.

4. Administration Techniques

Induction Agent Administration:

• Administer induction agents rapidly to achieve sedation and facilitate intubation.
• Ensure titration of medications to achieve desired sedation level without compromising hemodynamics.

Neuromuscular Blocking Agent Administration:

• Administer NMBAs after confirming adequate sedation to prevent patient awareness and facilitate intubation.
• Monitor for onset of paralysis and ensure proper ventilation during apnea phase.

5. Monitoring and Management

Monitoring:

• Continuously monitor vital signs including heart rate, blood pressure, oxygen saturation, and ECG if possible.
• Monitor level of sedation and depth of paralysis to adjust as necessary.

Management:

• Be prepared to manage potential complications such as hypotension, respiratory depression, or adverse reactions to medications.
• Have reversal agents available if needed (e.g., naloxone for opioid-induced respiratory depression).

6. Post-Intubation Care

Securing the Airway:

• Confirm proper placement of the endotracheal tube (ETT) using clinical and adjunctive methods (e.g., end-tidal CO2 monitoring).
• Secure the ETT and confirm effective ventilation.

Continued Monitoring:

• Maintain continuous monitoring of vital signs and oxygenation.
• Prepare for transport to appropriate medical facility, ensuring ongoing airway management and support.

7. Special Considerations

Pediatric and Geriatric Patients:

• Adjust medication doses and techniques based on age, weight, and physiological differences.

Difficult Airway Management:

• Be prepared for difficult intubations and have backup plans in place (e.g., alternative airway devices, surgical airway equipment).

Patient Condition:

• Consider comorbidities and potential contraindications to specific medications based on patient history.

8. Training and Proficiency

Simulation Training:

• Regular practice in simulated scenarios to maintain proficiency in intubation medication administration and airway management techniques.

Continuing Education:

• Stay updated on current guidelines, best practices, and new medications relevant to intubation and airway management.

9. Legal and Ethical Considerations

Scope of Practice:

• Adhere to the legal scope of practice for their certification level and local regulations.

Informed Consent:

• Obtain informed consent from the patient or guardian whenever possible, considering the urgency and necessity of the procedure.

Documentation:

• Accurate documentation of medication administration, intubation process, airway assessment, and ongoing patient monitoring.

Conclusion

Medication administration for RSI is a critical skill for EMS Providers performing advanced airway management. It requires proficiency in medication administration, airway assessment, and management of potential complications.

Continuous training, adherence to protocols, and effective teamwork are essential for ensuring successful patient outcomes in emergency situations.
