Recently published guidelines for checking anaesthetic equipment do not contain specific advice on how to check the correct functioning of the capnograph before inducing anaesthesia. ⋯ The most common method for testing capnograph function among consultant anaesthetists and their assistants in the UK is the direct measurement of exhaled breath.

Randomized Controlled Trial Comparative Study
Comparison of face masks in the bag-mask ventilation of a manikin.
We conducted a study investigating the effectiveness of four face mask designs in the bag-mask ventilation of a special manikin adapted to simulate a difficult airway. ⋯ There was a large variation in both performance and satisfaction between anaesthetists with each design. This highlights the importance of having a variety of face masks available for emergency use.

The potential for increased drug administration errors during the transition to the International Colour Coding syringe labelling system has been highlighted. The purpose of this study was to assess the potential effects before their introduction into our department. ⋯ Although only one drug was given in active error, latent errors occurred in 15% of drug administrations. The only factor conferring protection against error was prior experience of the new labelling system. The period of transition to the International Colour Coding syringe labelling system represents a time of increased risk of drug administration error.

We conducted this study in order to evaluate the potential myotoxic effects of ropivacaine after single injection in rats and the time-course of the possible damage. ⋯ Ropivacaine after single intramuscular injection caused reversible muscle damage in a dose-dependent manner.

Patients have the right to be informed about the expected benefits and risks of medical and surgical procedures. Ideally this information should be scientifically based and presented to the patient in time. In morbidly obese patient undergoing general anaesthesia, postoperative pulmonary complications are an important cause of postoperative morbidity and mortality. A 46-yr-old female with a body mass index of 89.8 kg m(-2) was scheduled to undergo radical abdominal surgery for cervix carcinoma. In order to inform her accurately on the risk of developing postoperative pulmonary complications, we undertook to answer the following question: What is the risk to develop postoperative pulmonary complications in a morbidly obese patient about to undergo abdominal surgery under general anaesthesia? ⋯ Considering the positive correlation coefficient and the high body mass index of this patient she has a risk of at least 29.3% to develop pneumonia and/or atelectasis, which should affect the anaesthetic strategy in this patient.
