Abstract
- <bold>Background: </bold>Thiol/disulfide homeostasis is a significant parameter in determining the oxidative stress response after ischemia and reperfusion. We aimed to investigate the effects of applying different intraabdominal pressure (IAP) on thiol/disulfide homeostasis, ischemia-modified albumin (IMA) levels, and hemodynamics in pediatric laparoscopic surgery.<bold>Materials and Methods: </bold>Blood samples were collected from 36 pediatric patients who were planned to undergo laparoscopic surgery for nonpalpable testis or varicocele under general anesthesia, immediately after intubation as the baseline and 5 minutes after abdominal desufflation for determining the thiol/disulfide, and IMA levels. The patients were divided into two groups; group 1 received a pneumoperitoneum pressure of 8 mm Hg (n = 18), and group 2 received 12 mm Hg (n = 18). The clinical characteristics and thiol/disulfide homeostasis and IMA levels of the patients were compared.<bold>Results: </bold>No difference was detected regarding the clinical features between the groups. The comparison after intubation and after desufflation in group 1 demonstrated lower native thiol (453 ± 67 versus 422 ± 57 μmol/L, P = .059) and total thiol (497 ± 73 versus 466 ± 62 μmol/L, P = .061) levels, which was statistically insignificant. The serum native thiol level was found lower than baseline in group 2 where a 12 mm Hg IAP was applied, this difference was not statistically significant (429 ± 47 versus 412 ± 53 μmol/L, P = .078). The comparison of serum IMA levels after desufflation with the baseline (0.505 ± 0.018 versus 0.632 ± 0.022) in group 2 was found statistically significantly high (P = .031). The comparison of the perioperative heart rate and SpO2 levels with before induction was found statistically insignificant.<bold>Conclusions: </bold>Neither of 8 nor 12 mm Hg IAPs in pediatric laparoscopic surgery caused any changes in novel indicators of thiol/disulfide homeostasis parameters; however, 12 mm Hg IAP increased the levels of IMA.
