[Central and cerebral hemodynamics during gynecological laparoscopic interventions in children]

The authors examined central and cerebral hemodynamics in children during gynecological laparoscopic interventions. The course of 64 anesthesias was analyzed in girls aged 3 to 16 years, who had undergone laparoscopic surgery. Central hemodynamics was studied by tetrapolar rheography on a Diamant apparatus; cerebral oximetry was examined on a Critikon RedOx Monitor 2020 device. The findings demonstrate that pneumoperitoneum application causes immediate cardiovascular changes. Transfer of patients to Trendelenburg's position had a beneficial impact on central hemodynamics, by facilitating the normalization of venous return, thus maintaining cardiac output. Central hemodynamic disorders promptly affected cerebral blood volume and oxygen status. After pneumoperitoneum application, there was an average of 3% reduction in regional cerebral tissue saturation.
