Conscious sedation for pediatric orthopaedic emergencies

Area of Science:

• Pediatric Emergency Medicine
• Pharmacology
• Sedation Management

Background:

• Conscious sedation (CS) is frequently used in pediatric emergency departments for painful procedures.
• Fentanyl and midazolam are common agents for CS, but their safety profile requires ongoing evaluation.
• Implementing standardized protocols is crucial for safe CS administration.

Purpose of the Study:

• To evaluate the safety and efficacy of conscious sedation using fentanyl and midazolam for fracture and dislocation reductions in children.
• To identify risk factors associated with complications during pediatric CS.
• To assess the effectiveness of a newly implemented CS protocol.

Main Methods:

• Retrospective review of 339 pediatric patients undergoing CS for fracture/dislocation reduction over 22 months.
• Data collected via standardized CS forms, analyzed using descriptive statistics and inferential tests (chi-squared, Fisher's exact, t-test, logistic regression).
• Assessment of complications, including respiratory status changes, vomiting, and need for interventions.

Main Results:

• The majority of patients (339) experienced minor complications, with 11.0% having altered respiratory status.
• Most respiratory events were mild, requiring minimal intervention (e.g., oxygen, breathing reminders, airway maneuvers).
• Female sex (OR=2.2) and deep sedation (OR=2.7) were associated with increased risk of respiratory events; no patients required intubation or admission due to CS complications.

Conclusions:

• Fentanyl and midazolam administered via protocol for pediatric CS are associated with a low rate of minor complications.
• Female patients and those experiencing deep sedation may have a slightly higher risk of respiratory alterations.
• Continuous monitoring of vital signs is essential for ensuring patient safety during conscious sedation.
