Randomized Controlled Trial Comparative Study[Sedation and analgesia with propofol plus low-dose ketamine for retrobulbar block].
To determine if adding ketamine to propofol provides better sedation than propofol alone for patients receiving a retrobulbar block for eye surgery. ⋯ Low doses of ketamine associated with propofol improve puncture conditions for performing a retrobulbar block without increasing unwanted side effects.

Randomized Controlled Trial Comparative Study[Addition of sodium bicarbonate and/or clonidine to mepivacaine: influence on axillary brachial plexus block characteristics].
The axillary brachial plexus block is a frequently performed anesthetic technique. Adding a variety of coadjuvant drugs has been shown to improve results. This study evaluated the addition of sodium bicarbonate (NaHCO3) and/or clonidine to mepivacaine for performing the block. ⋯ Adding NaHCO3 to mepivacaine shortens the time of onset of an axillary brachial plexus block. Including clonidine prolongs the duration of anesthesia and analgesia. The addition of both NaHCO3 and clonidine shortens time to onset but does not prolong duration of anesthesia or analgesia.
