Insights
This simulation enhances anesthesiology residents' skills in managing pediatric post-tonsillectomy hemorrhage. The training reinforces critical care and airway management for pediatric patients, with overwhelmingly positive learner feedback.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Medical Simulation
Background:
- Post-tonsillectomy hemorrhage is a critical event requiring prompt management by anesthesia providers.
- Pediatric patients may have comorbid conditions that complicate anesthesia care.
- Anesthesiology residents require training in managing such challenging pediatric cases.
Purpose of the Study:
- To reinforce knowledge and skills in managing pediatric post-tonsillectomy and adenoidectomy hemorrhage.
- To provide a challenging simulation for anesthesiology residents with prior pediatric anesthesia experience.
Main Methods:
- A simulation module delivered in 1 hour or less.
- Includes a case template, critical actions checklist, summary, and evaluation form.
- Designed for anesthesiology residents who have completed 1 year of clinical anesthesia and 1 month of pediatric anesthesia.
Main Results:
- Learner feedback was almost unanimously positive.
- All surveyed learners agreed or strongly agreed that the simulation enhanced their understanding of managing critically ill perioperative patients.
- Learners found the content current and relevant to their practice.
Conclusions:
- The simulation effectively reinforces troubleshooting skills for difficult IV line placement and airway management.
- The case can be modified to simulate more severe hemorrhage and hypovolemia.
- This training module is valuable for preparing residents for real-world pediatric anesthesia challenges.
Introduction:
Providers at all levels should have some understanding of the pathophysiology and be able to manage such a patient in the operating room. In addition, any anesthetists providing pediatric care should be able to identify and understand the importance of other comorbid conditions in these patients. This simulation on posttonsillectomy and adenoidectomy hemorrhage in the pediatric patient presents a challenging case usually encountered in some form by most anesthesia residents during training. This simulation's objective is to challenge and further reinforce the knowledge of anesthesiology resident physicians who have completed 1 year of clinical anesthesia and at least 1 month of pediatric anesthesia.
Methods:
The simulation can be delivered in a single session of 1 hour or less. Materials in this simulation include a case template designed to provide facilitators with a general overview, a checklist of critical actions each learner should perform during the scenario, a brief summary to be provided to the learner to reinforce knowledge gained through the activity, and an evaluation form to assess the learner's view of the activity's educational value.
Results:
Learner comments were almost unanimously positive. All learners who returned surveys answered the questions "This simulation enhanced my understanding of how to manage critically ill patients in the perioperative period" and "The content was current and relevant to my practice" with either agree or strongly agree.
Discussion:
The module offers various points to practice troubleshooting skills in the management of difficult IV line placement as well as difficult airway management. In reality, this case could be modified in multiple ways, including management of a more severe hemorrhage with a much more hypovolemic patient.
