Clinical TrialMidlatency auditory-evoked potentials in the assessment of sedation in cardiac surgery patients.
Midlatency auditory-evoked potentials (MLAEPs) may provide an objective measure of depth of sedation. The aim of this study was to evaluate MLAEPs for measuring sedation in cardiac surgery patients. ⋯ MLAEP latencies can reflect subtle changes in auditory perception, while amplitudes seem to change with transition between deep levels of sedation.

Clinical TrialAccuracy and performance of a modified continuous intravascular blood gas monitoring device during thoracoscopic surgery.
The only commercially available continuous intravascular blood gas monitoring system for adults, the Paratrend (Diametrics Medical Inc, High Wycombe, UK), was modified by the manufacturer to the Paratrend 7+ (PT7+) in 1999. The aim of this study was to evaluate the modified probe over a wide range of blood gas and pH values during thoracoscopic surgery in a similar setup as done with the previous model. ⋯ In patients undergoing thoracoscopic surgery with rapidly changing blood gas parameters, the PT7+ device is a valuable trend indicator and hence may be helpful for clinical decision making. However, the underestimation of PO(2) values by 20 mmHg on average and the wide limits of agreement documented in this study must be regarded as limiting factors.

Clinical TrialCerebral oxygen desaturation is associated with early postoperative neuropsychological dysfunction in patients undergoing cardiac surgery.
To evaluate the relationship between cerebral oxygen saturation and neuropsychological dysfunction after cardiac surgery. ⋯ Intraoperative cerebral oxygen desaturation is associated with early postoperative neuropsychological dysfunction in patients undergoing cardiac surgery with cardiopulmonary bypass. However, it remains to be determined whether interventions to maintain adequate cerebral oxygenation may improve neuropsychological outcome.

The aim of this study was to investigate cases of difficult intubation in pediatric cardiac surgical patients and to evaluate the importance of associated congenital abnormalities. ⋯ The likelihood of difficult intubation during pediatric cardiac surgery, especially in cases with other congenital pathologies should be kept in mind, and the anesthetic approach must be planned accordingly.
