Comparative StudyA comparison of the Internet and the standard textbook in preparing for the professional anaesthetic examination.
The Internet is increasingly being recognised as a source of information in different fields, and medicine is no exception. We investigated the use of the Internet as an aid in preparing for the professional medical examinations. The Internet was compared to a standard textbook in answering a randomly selected past examination paper. ⋯ In contrast, the textbook provided adequate information in only 73.3% of the questions. The time required to search for information on the Internet was more than that required for a single textbook. (approximately 2 hours per question compared to 30 minutes per question respectively). However, with the rapid development of computer technology and the cyberspace, the Internet may prove to be a viable alternative or a good supplement to the standard textbook when trainee anaesthetists are preparing for their professional medical examinations.

Patient's perceptions of an anesthesia preoperative computerized patient interview.
Our desire to elicit a more complete medical history from our patients led to the implementation of a preoperative computerized interview. We previously demonstrated the effectiveness of the interview by computing its mean completion time for the overall patient population (n = 120), and further examined the effects of age, gender, and educational level. In this study, we investigated patient perception of the interview itself. ⋯ The Stuart-Maxwell test was used to determine statistically significant differences in answers before and after the interview. Initial questionnaire responses reflected a positive attitude toward computer usage which became even stronger after the interview. The only negative responses elicited were really more "doctor positive" than "computer negative." We conclude that patients looked favorably upon participating in a computerized medical interview provided that physician-patient contact is maintained.

Comparative Study Clinical TrialMonitoring of heart and respiratory rates in newborn infants using a new photoplethysmographic technique.
A new photoplethysmographic (PPG) device for respiratory and heart rate monitoring has been evaluated in the neonatal care units at the University Children's Hospital of Uppsala, Sweden. The purpose of this study was to compare this new device with more established techniques, i.e., transthoracic impedance plethysmography (TTI) for monitoring of respiratory rate and ECG for heart rate monitoring. ⋯ Electrode and motion artefacts seem to disturb the ECG signals and, particularly, the impedance signals. During periods of high quality ECG and impedance signals, the new optical device produces signals of equal quality to these traditional methods, and is in some cases even better. The new device is non-invasive and has a small optical probe. These factors indicate further advantages of the photoplethysmographic method.
