Correlation between pre-anesthesia anxiety and emergence agitation in non-small cell lung cancer surgery patients

Table 1 Riker Sedation Agitation Scale

Point	Classify	Describe
1	Can't be awakened	The patient has a mild or no response to stimuli and is unable to communicate or follow instructions
2	Very calm	The patient responds to somatic stimuli but is unable to communicate and follow instructions
3	Calm	The patient is drowsy, can be awakened by verbal stimulation or gentle shaking, and can obey simple commands
4	Quiet cooperation	The patient is quiet, easily aroused, and obeys instructions
5	Agitation	The patient is anxious or physically agitated, tries to roll over and get up, can be quieted by verbal cues to discourage him or her
6	Very agitated	The patient requires protective restraint and repeated verbal prompts to discourage
7	Dangerous agitation	The patient pulls on the endotracheal tube, attempts to remove the internal catheter, rolls over the bed rails, unconsciously assaults healthcare workers, and struggles to roll over in the bed, requiring forcible restriction of his movements
