Benefits and Risk of Laryngeal Mask Airways

  • I want to talk about the benefits and risk of Laryngeal mask airways which you can use for fast procedures and stuff like that.
  • The resident nurse anesthesiologist will critically evaluate the clinical experience, and learning environment at the clinical site for reflection and growth in learning.
  • Compare and contrast what is learned in the classroom setting and what is common clinical practice and challenges this brings to the students growth in learning. What can you change and learn from your experience?

benefits and risk of Laryngeal mask airways

The use of Laryngeal Mask Airways (LMAs) in clinical settings has several benefits and risks that play a crucial role in shaping the learning experience for student nurses, particularly those studying anesthesia or critical care. LMAs are commonly used in fast procedures or situations where endotracheal intubation may be difficult, as they provide a secure airway with less invasiveness.

Benefits of Laryngeal Mask Airways:

  1. Quick Insertion: LMAs are quicker to insert compared to endotracheal tubes, making them beneficial in emergency situations or for shorter procedures.
  2. Less Invasive: Compared to endotracheal intubation, the LMA is less invasive, reducing the likelihood of damage to the trachea or vocal cords.
  3. Adequate Airway Protection: LMAs provide adequate airway protection in most cases, making them suitable for many routine surgeries and anesthesia cases.
  4. Ease of Use: LMAs are relatively easier to insert, and they require less technical skill compared to traditional intubation, making them useful in settings where rapid airway management is needed.
  5. Comfort for Patients: LMAs tend to cause less discomfort post-procedure compared to endotracheal tubes, contributing to a quicker recovery time for patients.

Risks of Laryngeal Mask Airways:

  1. Limited Airway Control: While LMAs provide an adequate airway in many cases, they may not be as effective as endotracheal intubation in securing a definitive airway, especially in patients with high aspiration risk or those requiring deep levels of anesthesia.
  2. Possible Malpositioning: Incorrect placement of the LMA can lead to ineffective ventilation or airway obstruction.
  3. Risk of Aspiration: In certain patient populations, LMAs may not fully protect against aspiration, particularly in those with a full stomach or in emergency situations.
  4. Potential for Injury: There is a risk of trauma to the airway, such as mucosal injury, especially if the device is not inserted properly or used inappropriately.
  5. Limited to Certain Procedures: LMAs are typically used for short-duration procedures and may not be suitable for longer surgeries or complex cases where intubation is required for more controlled ventilation.

Reflection on Classroom Learning vs. Clinical Practice:

In the classroom setting, students are often taught about the theoretical aspects of airway management, including the indications and contraindications of devices like LMAs, their mechanisms of action, and their proper use. However, clinical practice often brings about challenges that go beyond textbook knowledge. Some of these include:

  1. Real-World Challenges: In the clinical setting, students may face real-time challenges such as patient variability, airway anatomy differences, and the pressure of performing under time constraints. For example, while a textbook might describe LMA insertion as relatively simple, students in the clinical setting may find it difficult due to factors like patient positioning, body habitus, or the urgency of the procedure.
  2. Skill Development: Classroom learning may not fully prepare students for the tactile feedback or the nuances of inserting an LMA in a patient who is not in ideal conditions, such as in a challenging airway or emergency scenario. The experience of feeling resistance during insertion or being asked to adapt quickly to changing conditions sharpens students’ clinical skills.
  3. Critical Thinking: In the classroom, students learn the theoretical protocols for managing airway emergencies. However, in the clinical setting, critical thinking is required when there are multiple possible airway devices to use. The student has to analyze the patient’s condition and determine which device is best suited for the situation.
  4. Patient Interaction: In a clinical setting, students may experience the human element of care that isn’t always covered in textbooks, such as managing patient anxiety or ensuring patient comfort during the procedure. This aspect of care can be as important as the technical skills required for airway management.

Growth in Learning and Opportunities for Change:

To foster growth in learning, the following changes could be implemented:

  1. Simulated Training: Before performing procedures on real patients, students should have more access to high-fidelity simulation training. This would allow them to practice LMA insertion and management in a controlled environment that mimics real clinical scenarios. This would build confidence and allow students to make mistakes without patient risk.
  2. Supervised Practice: More hands-on practice under direct supervision from experienced nurse anesthesiologists or clinicians is essential. Clinical instructors should offer constructive feedback and guide students through complex situations, encouraging them to reflect on their practice to improve.
  3. Patient-Centered Focus: In clinical practice, there should be more emphasis on patient education and communication, as these aspects often shape a student’s overall experience. Learning how to approach patients, ease their anxieties, and communicate effectively with the surgical team is crucial for both patient safety and student development.
  4. Post-Procedure Reflection: Encouraging students to participate in post-procedure discussions or debriefings can help them analyze what went well and where improvement is needed. Reflecting on what was learned from both successes and challenges in clinical practice will help students grow in their roles.

By embracing these changes and maintaining a reflective approach to their experiences, students can bridge the gap between classroom knowledge and clinical expertise, leading to better patient outcomes and professional development in the field of anesthesia and critical care.
