Review Comparative Study
Recovery advantages of regional anesthesia compared with general anesthesia: adult patients.
The data support but do not conclusively prove, that RA results in a superior recovery compared with GA. However, several questions need to be answered. ⋯ Anesthetic techniques need to be carefully compared to determine whether they are equal in quality, efficiency, and cost. Finally, to determine whether RA is cost-effective, future studies involving ambulatory patients with a focus on outcome and well-being need to be conducted.

Can learning occur during general anaesthesia? This paper reviews the studies which have addressed this issue and finds some evidence of implicit memory for intra-operative events, even with clinically adequate anaesthesia. This has implications both for clinical practice and for psychological theories of learning and awareness. ⋯ Methodological improvements are discussed, in particular the need for a reliable means of monitoring awareness during anaesthesia. These improvements would enable researchers to determine the conditions under which learning occurs and would provide information about the role of consciousness in learning.

We aimed to describe the frequency of atelectasis occurring during anaesthesia, to describe the size and pattern of the atelectasis, and to standardise the method of identifying the atelectasis and calculate its area. ⋯ On the basis of the present findings, we defined atelectasis as pulmonary dependent densities with attenuation values of -100 to +100 HU.

Preschool children depend on their parents for support and guidance in dealing with new or stressful situations. When requested, the parents should be allowed to support their children during ambulatory surgical procedures, especially during the induction of anesthesia. With proper understanding on our part, and with proper preparation and counseling, the parents can become our allies and help to smooth the experience for the child, for the staff, and for themselves. Future efforts should be directed at studying the effects of different methods of preoperative preparation and counselling on the parents' attitude and cooperation during induction.
