Anaesthesia and intensive care
-
Advanced haemodynamic monitoring remains a cornerstone in the management of the critically ill. While rates of pulmonary artery catheter use have been declining, there has been an increase in the number of alternatives for monitoring cardiac output as well as greater understanding of the methods and criteria with which to compare devices. The PiCCO (Pulse index Continuous Cardiac Output) device is one such alternative, integrating a wide array of both static and dynamic haemodynamic data through a combination of trans-cardiopulmonary thermodilution and pulse contour analysis. ⋯ While the accuracy of trans-cardiopulmonary thermodilution as a measure of cardiac output is well established, several other PiCCO measurements require further validation within the context of their intended clinical use. As with all advanced haemodynamic monitoring systems, efficacy in improving patient-centred outcomes has yet to be conclusively demonstrated. The challenge with PiCCO is in improving the understanding of the many variables that can be measured and integrating those that are clinically relevant and adequately validated with appropriate therapeutic interventions.

Anaesth Intensive Care · May 2012
ReviewCircumcision of neonates and children without appropriate anaesthesia is unacceptable practice.
Circumcision is painful surgery and appropriate intraoperative anaesthesia and postoperative analgesia is required. This is recognised in the policies of the Royal Australasian College of Physicians and the majority of Australian State Health Departments. Nevertheless, anecdotal evidence exists that neonatal circumcision continues to be performed in Australia with either no anaesthesia or with inadequate anaesthesia. ⋯ The authors conclude that general anaesthesia is arguably the most reliable way of ensuring adequate anaesthesia, although this may mean deferment of the procedure until the child is older. Local or regional anaesthesia for neonatal circumcision ideally requires a separate skilled anaesthetist (other than the proceduralist) to monitor the patient and intervene if the anaesthesia is inadequate. Topical anaesthesia with lignocaine-prilocaine cream is insufficient.
