The use of interscalene block as the

While the medical literature includes an occasional description of hypnosis being used as the

Although there may be numerous mechanisms by which NMDA receptor antagonism promote early apoptosis in cultured cells, this data supports the theory that cell cycle activation may play an important role in the potential cognitive effect suggested by clinical studies using Ketamine as
primary anesthetic agent.
