, Anesthesia
• For patients undergoing surgical or medical procedures, different
levels of sedation can provide important benefits
• to facilitate procedural interventions. These levels of sedation
range from anxiolysis to general anesthesia and can create:
• Sedation and reduced anxiety
• Lack of awareness and amnesia
• Skeletal muscle relaxation
• Suppression of undesirable reflexes
• Analgesia
, General anesthesia
• General anesthesia is a reversible state of central nervous
system (CNS) depression, causing loss of response to and
perception of stimuli.
• Because no single agent provides all desired objectives, several
categories of drugs are combined to produce the optimum leve
of sedation required (adjunct agents)
