Randomized Controlled Trial Clinical Trial
Learning by computer simulation does not lead to better test performance than textbook study in the diagnosis and treatment of dysrhythmias.
To compare computer-based learning with traditional learning methods in studying advanced cardiac life support (ACLS). ⋯ Studying ACLS with a hard-copy textbook may be more effective than computer simulation for acquiring simple information during a brief period. However, the difference in effectiveness is likely transient.

Comparative Study
A comparison of Internet usage between two residency programs in the United Kingdom and the United States.
To survey the pattern of use and availability of the Internet among anesthesia residents. ⋯ If the reported survey results are representative of Internet use among anesthesia residents in the United States and UK, Internet access at work is associated with greater Internet use for medical purposes, perhaps in part because residents perceive it to be a convenient and accurate resource.

To determine the influence of head and neck elevation beyond the "sniffing position" during difficult direct laryngoscopy. ⋯ Elevation of the head and neck beyond the sniffing position may improve visualization of glottic structures in cases of difficult direct laryngoscopy, leading to better intubation performance.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of effects of lidocaine hydrochloride, buffered lidocaine, diphenhydramine, and normal saline after intradermal injection.
To evaluate pain and the spread of analgesia when local anesthetics are given as an intradermal injection into the dorsal aspect of the hand. ⋯ There is a reduction of infiltration pain using buffered lidocaine as opposed to lidocaine and diphenhydramine. Although lidocaine injection resulted in a slightly faster spread of analgesic diameter, buffered lidocaine was equivalent to lidocaine from minute 2 until minute 30. Therefore, to obtain optimal anesthetic conditions, we recommend that buffered lidocaine be given 2 minutes before performing catheterization, whereas diphenhydramine should be given 5 minutes before catheterization, but only when buffered lidocaine cannot be used.
