Abstract

Background In this study we tested the hypothesis that maternal pneumoperitoneum produces early postnatal behavior deficits in the offspring Methods Timedated pregnant guinea pigs were exposed to 45 min of carbon dioxide CO2 pneumoperitoneum at a pressure of 7 mmHg There was no manipulation of the control animals On postnatal days PND 10 and 20 the behavior of their offspring was assessed by monitoring the locomotor activity of each of the pups in a 1 × 1 m chamber demarcated into 100 squares Locomotor data was logtransformed and expressed as mean values SD Results At PND 10 pneumoperitoneum offspring exhibited significantly higher levels of locomotor activity than the offspring of controls 181 ± 048 vs 133 ± 078 The pneumoperitoneum pups continued to exhibit hyperactive behavior at PND 20 183 ± 072 vs 120 ± 072 Conclusions Maternal pneumoperitoneum produces postnatal hyperactivity in guinea pig offspring suggesting that there may be longterm consequences associated with the physiologic changes produced in the fetus during CO2 insufflation
