Is routine preanesthetic hemoglobin test necessary in minor pediatric surgery?
The value of preanesthetic assessment of anemia and analysis of the hemoglobin level prior to a minor pediatric surgery has been recently questioned in some reports. This study was to retrospectively analyse 8859 pediatric patients who underwent minor surgery in the period from January 1987 to December 1990 in our hospital. They were all ASA class I-II in physical status with age ranging from one month to 19 years. Those patients with their hemoglobin values determined at other laboratories or hospitals in spite of our recognition and those suspected of having an immune or oncologic disease were excluded from this study. The mean hemoglobin value of the patients under study was 12.99 +/- 0.82 g/dl. 0.62% of the patients (55) were found to have hemoglobin values less than 10 g/dl which were similar to the results obtained by Wood et al (0.7%) in 1981 and Roy et al (0.5%) in 1990. Among the 55 anemic patients, 41 (74.5%) were at the age between 2 to 4 months (within the physiologic anemic period of infancy). Sampling of blood for routine preanesthetic hemoglobin determination which caused discomfort and pain was often rejected by pediatric patients and struggle for escape also upset the children very much. Based on the results from our analysis, we suggest that in healthy pediatric patient scheduled for minor surgery routine hemoglobin test could be excluded. Hemoglobin test is selectively performed in a patient is anemic or under suspicious circumstances. The value and shortcomings of selective hemoglobin test before surgery require further evaluation.
