One of your roles is to monitor the effects of anesthetics on your client's vital signs, paying close attention to respiratory status (respiratory rate, depth, quality, and SpO2), as well as their level of consciousness and pain level.\n\nThere are three categories of anesthetics:\n<ul>\n \t<li><strong>Local: <\/strong>Local anesthetic is when a medication (e.g., lidocaine) is injected into the skin at the site of the procedure to achieve numbness for procedures like suturing. EMLA cream is a combination of lidocaine and prilocaine used before procedures such as starting intravenous (IV) access, especially for children. Read more information about lidocaine and EMLA cream in Table 10.11.<\/li>\n \t<li><strong>Conscious Sedation: <\/strong>Conscious sedation is a combination of medications that allow the client to be relaxed (midazolam) and free of pain (e.g., fentanyl) during a medical procedure (e.g., colonoscopy). This allows the client to remain awake and aware, without feeling discomfort. The client may or may not be able to speak or respond in this state.<\/li>\n \t<li><strong>General Anesthesia: <\/strong>General anesthesia is a medication-induced reversible unconsciousness with loss of protective reflexes. Arousal, even to painful stimuli, cannot occur. General anesthesia requires the establishment and maintenance of airway control.<sup>[footnote]Frandsen, G., &amp; Pennington, S.
