Cognitive outcome after spinal anesthesia and surgery during infancy

Area of Science:

• Pediatric Anesthesiology
• Neurodevelopmental Pediatrics
• Pediatric Surgery

Background:

• General anesthesia (GA) concerns in pediatrics are confounded by surgical need.
• Previous studies linked GA duration to lower test scores in children.
• A subgroup with very poor academic achievement (VPAA) was identified.

Purpose of the Study:

• To investigate the long-term effects of spinal anesthesia (SA) on academic achievement in children.
• To differentiate anesthesia effects from surgical factors in pediatric neurodevelopment.
• To assess the association between infant SA exposure and VPAA.

Main Methods:

• A novel database linked medical and educational records for 265 students exposed to SA in infancy.
• Students receiving SA for specific procedures were compared to a matched control group.
• Academic performance on standardized tests was analyzed.

Main Results:

• Infant SA and surgery duration showed no significant effect on VPAA.
• No relationship was found between SA exposure duration and math or reading scores.
• A small, statistically significant decrease in reading and math scores was noted in the SA-exposed group.

Conclusions:

• Infant SA exposure was not linked to VPAA in elementary school children.
• No association was found between SA duration and academic achievement.
• While VPAA was not linked, a slight score decrease warrants further investigation.
