Comparative StudyLack of agreement and trending ability of the endotracheal cardiac output monitor compared with thermodilution.
Minimally invasive monitoring systems of central haemodynamics are gaining increasing popularity. The present study investigated the precision of the endotracheal cardiac output monitor (ECOM) system and its agreement with pulmonary artery catheter thermodilution (PAC TD) for measuring cardiac output (CO) during steady state and with induced haemodynamic changes in patients scheduled for elective cardiac surgery. ⋯ In a direct comparison with PAC TD, the ECOM system did not show an acceptable agreement, with wide limits of agreement, a much larger percentage error than should be expected from the precision of the two methods and a very poor trending ability. Thus, the ECOM does not replace measurements done by thermodilution using a pulmonary artery catheter in cardiac surgery patients.

Reliability and validity of the Swedish version of the modified Yale Preoperative Anxiety Scale.
The modified Yale Preoperative Anxiety Scale (m-YPAS) is an observational behavioral checklist that has been widely used as an indicator of pre-operative anxiety in children. The present study describes the translation process of m-YPAS into Swedish and the testing of its reliability and validity when used with Swedish children. ⋯ This validation study of the Swedish version of the m-YPAS shows good consistency, interrater validity, and construct validity when used by experienced assessors.

Outcome of spontaneous and iatrogenic pneumothoraces managed with small-bore chest tubes.
Little is known about the efficacy of management of iatrogenic pneumothoraces with small-bore chest tubes. The aim of this study was to assess the outcome of iatrogenic pneumothoraces requiring drainage managed with a small-bore chest tube and to compare the results to spontaneous pneumothoraces treated in the same unit with the same device. The primary outcome was requirement of video-assisted thoracoscopic surgery for drainage failure; secondary outcomes were length of drainage and number of inserted chest tubes. ⋯ Small-bore chest tubes are feasible for treatment of iatrogenic pneumothoraces and have a better rate of success and slightly longer drainage duration than when used for spontaneous pneumothoraces.
