Brazilian Studies

There are few Brazilian studies on neuropsychomotor follow-up after open-heart surgery with circulatory bypass in infants. Twenthy infants had neurodevelopmental outcomes (neurological exam and Denver II test) assessed before open-heart surgery, after intensive care unit discharge and 3-6 months after hospital discharge. Heart lesions consisted of septal defects in 11 cases (55%). The mean circulatory bypass time was 67 ± 23.6 minutes. Fifteen infants had altered neurological examination and also neurodevelopment delay before surgery. After 6 months it was observed normalization in 6 infants. When Denver II test indexes were analysed, it was observed an improvement in all domains except personal-social. Although those infants were in risk of new neurological findings, an early improvement on neuropsychomotor indexes were seen.

The Relationship

Abstract We studied 16 patients undergoing open-heart surgery and heart-lung bypass, to examine the relationship between ionized calcium and lactate. Blood was sampled at successive stages of the operation for measurement of ionized and total calcium, lactate, blood gases, pH, hematocrit, and other constituents. We found that correlations between ionized calcium and lactate were positive and statistically significant (p less than 0.05), both among and within patients. The linear regression of ionized calcium on lactate remained highly significant (p less than 0.0001) after adjustment for variability among patients and across operative stages as well as after correction for pH and hemodilution. The significant regressions between calcium and lactate, both before and after administration of calcium, indicate a relationship for calcium and lactate in patients undergoing open-heart surgery.

Cognitive Test Performance

Performance on many cognitive and neuropsychological tests may be improved by prior exposure to testing stimuli and procedures. These beneficial practice effects can have a significant impact on test performance when conventional neuropsychological tests are administered at test–retest intervals of weeks, months or years. Many recent investigations have sought to determine changes in cognitive function over periods of minutes or hours (e.g., before and after anesthesia) using computerized tests. However, the effects of practice at such brief test–retest intervals has not been reported. The current study sought to determine the magnitude of practice effects in a group of 113 individuals assessed with an automated cognitive test battery on 4 occasions in 1 day. Practice effects were evident both between and within assessments, and also within individual tests. However, these effects occurred mostly between the 1st and 2nd administration of the test battery, with smaller, nonsignificant improvements observed between the 2nd, 3rd, and 4th administrations. On the basis of these results, methodological and statistical strategies that may aid in the differentiation of practice effects from drug-induced cognitive changes are proposed.
