Is routine pre-operative blood testing in children necessary?

Area of Science:

• Pediatric Surgery
• Clinical Pathology

Background:

• Pre-operative investigations are standard for surgical patients.
• Their utility in low-risk pediatric cases requires evaluation.

Purpose of the Study:

• To assess the value of routine pre-operative investigations in children undergoing minor elective surgery.
• To determine if these tests impact patient management or surgical outcomes.

Main Methods:

• Retrospective chart review of 342 pediatric patients.
• Analysis of pre-operative tests (blood count, electrolytes) for abnormalities.
• Correlation of abnormal results with management changes, complications, and costs.

Main Results:

• 9.2% of tests showed abnormalities, mostly clinically insignificant.
• No surgeries were postponed due to test results.
• No complications were predicted by pre-operative screening.

Conclusions:

• Routine pre-operative blood testing has minimal value in pediatric minor surgery.
• Clinical assessment (history and physical exam) is more important.
• Tests can cause discomfort without significant clinical benefit.
