Comparative Study
Comparison of cardiac output measurements between NICO and the pulmonary artery catheter during repeat surgery for total hip replacement.
The aim of this study was to compare cardiac output measurements of the non-invasive cardiac output and the pulmonary artery catheter during repeat surgery for hip replacement. ⋯ The perioperative bias was small and the non-invasive cardiac output slightly underestimated cardiac output intraoperatively compared to the pulmonary artery catheter. The bias was smaller when mean cardiac output was below 3 L min(-1). Core temperature between 34.4 degrees C and 37.6 degrees C had no influence on the differences.

This study follows up an initial audit in 1992 indicating that anaesthetic machine checking practices were often incomplete. The aims were to ascertain if there has been any improvement during this period with special reference to the latest guidelines. ⋯ Although there has been a significant increase in the proportion of anaesthetists undertaking machine checks since 1992 (P = 0.0007), we conclude that machine checking guidelines are still poorly followed, with checks specific to the latest guidelines most likely to be omitted.
