Randomized Controlled Trial Multicenter Study Clinical Trial[Explicit and implicit memory during inhalation and intravenous anesthesia].
Patients rarely report memory or knowledge of surgery after general anesthesia. During apparently adequate surgical anesthesia, however, information processing of high level functions, such as language comprehension and learning, can continue unconsciously. Our objective is to assess whether different anesthetic techniques (two inhalational and two intravenous) guarantee the absence of both types of memory. ⋯ Explicit memory was absent with all four anesthetic techniques used in our study. Implicit memory was more difficult to inhibit, however, with isoflurane/N2O.

Randomized Controlled Trial Clinical Trial[Arm adduction does not increase block extension in anesthesia of the brachial plexus by the axillary approach].
Arm abduction of 90 degrees during injection of local anesthetic followed by adduction of the arm has been recommended traditionally to favor proximal distribution of local anesthetic and extension of the blockade in the brachial plexus by the axillary route. A recent study demonstrated that there are no clinical or radiological differences between axillary blockades performed with abduction or adduction. ⋯ Axillary rotation of the arm is not a determining factor in sensory blockade in brachial plexus anesthesia by the axillary route.
