Comparative Study
The accuracy of trained nurses in pre-operative health assessment: results of the OPEN study.
We quantified the accuracy of trained nurses to correctly assess the pre-operative health status of surgical patients as compared to anaesthetists. The study included 4540 adult surgical patients. Patients' health status was first assessed by the nurse and subsequently by the anaesthetist. ⋯ In 1.3% (95% CI: 1.0-1.6%) of patients, nurses classified patients as 'ready' whereas anaesthetists did not. Nurses required 1.85 (95% CI: 1.80-1.90) times longer than anaesthetists. By allowing nurses to serve as a diagnostic filter to identify the subgroup of patients who may safely undergo surgery without further diagnostic workup or optimisation, anaesthetists can focus on patients who require additional attention before surgery.

We describe a simple, homemade model for teaching cricothyrotomy. It can easily be constructed from materials found in every anaesthetic room and is cheap, portable and usable several times before requiring replacement. We also describe evaluation of the model in a two-part study. ⋯ In the second part, both models were rated well, with similar scores. The homemade model is an easily assembled alternative to more expensive models. Both experienced and inexperienced trainees find practising on such models useful.

The addition of epinephrine to solutions containing fentanyl and bupivacaine for epidural infusion has been shown to improve the quality of analgesia. However, this admixture is not available commercially in the United Kingdom. ⋯ All infusions were found to be stable over the study period (> 90% remaining) using stability-indicating High Performance Liquid Chromatography (HPLC) methods, with no changes in physical appearance or pH (range 4.5-4.2). The infusions were prepared using standard pharmaceutical products, so facilitating the batch preparation of epinephrine, fentanyl and bupivacaine epidural solutions by hospital pharmacy departments.
