Pediatric MRI Without Anesthesia: The Effect of Application-Supported Communication to Prepare the Child

Nonpharmacological Interventions to Reduce Sedation and General Anesthesia in Pediatric MRI: A Meta-analysis

CONTEXT

Nonpharmacological strategies are increasingly used in pediatric procedures, but in pediatric MRI, sedation and general anesthesia are still commonly required.

OBJECTIVES

To evaluate the effectiveness of nonpharmacological interventions in reducing use of sedation and general anesthesia in pediatric patients undergoing MRI, and to investigate effects on scan time, image quality, and anxiety.

DATA SOURCES

We searched Ovid Medline, CINAHL, Embase, and CENTRAL from inception through October 10, 2022.

STUDY SELECTION

We included randomized controlled trials and quasi-experimental designs comparing the effect of a nonpharmacological intervention with standard care on use of sedation or general anesthesia, scan time, image quality, or child and parental anxiety among infants (<2 years), children, and adolescents (2-18 years) undergoing MRI.

DATA EXTRACTION

Standardized instruments were used to extract data and assess study quality.

RESULTS

Forty-six studies were eligible for the systematic review. Limited to studies on children and adolescents, the meta-analysis included 20 studies with 33 873 patients. Intervention versus comparator analysis showed that nonpharmacological interventions were associated with reduced need for sedation and general anesthesia in the randomized control trials (risk ratio, 0.68; 95% confidence interval, 0.48-0.95; l2 = 35%) and nonrandomized studies (risk ratio, 0.58; 95% confidence interval, 0.51-0.66; l2 = 91%). The effect was largest among children aged 3 to 10 years when compared with older children and adolescents aged 11 to 18 years.

LIMITATIONS

There was substantial heterogeneity among nonrandomized studies.

CONCLUSIONS

Nonpharmacological interventions must be considered as standard procedure in infants, children, and adolescents undergoing MRI.

An update on pediatric sedation techniques in nonoperating room locations

PURPOSE OF REVIEW

To review advancements in care for pediatric patients in nonoperating room settings.

RECENT FINDINGS

Advances in patient monitoring technology, utilization of Child Life specialists, and alternative staffing models are helping anesthesia providers meet the rising demand for coverage of pediatric nonoperating room anesthesia (NORA) cases. The Wake Up Safe and Pediatric Sedation Research Consortium registries are exploring outcome measures regarding the safety of pediatric anesthesia in off-site locations and have reported an increased risk for severe respiratory and cardiac adverse events when compared to OR anesthesia sites. Additionally, malpractice claims for NORA have a higher proportion of claims for death than claims in operating rooms.

SUMMARY

Pediatric NORA requires thorough preparation, flexibility, and vigilance to provide safe anesthesia care to children in remote locations. Emerging techniques to reduce anesthetic exposure, improve monitoring, and alternative staffing models are expanding the boundaries of pediatric NORA to provide a safer, more satisfying experience for diagnostic and interventional procedures.
