65
May be used to induce and/or maintain anesthesia. May be combined with inhalation anesthetics or used alone
Inhalation
66
Characteristics of patients receiving RA (Regional Anesthesia)
Awake
Aware of sorroundings unless intentionally sedated
67
Mechanism of Action of Regional Anesthesia
An Anesthetic agent is injected around nerves so that the region supplied by these nerves is anesthetized.
68
Things to avoid when patient is injected with regional anesthesia
Health care team must avoid careless conversation, unnecessary noise, and unpleasant odors because these may be noticed by the patient in the OR and may contribute to a negative response to the surgical experience.
69
Achieved by injecting a local anesthetic agent into the epidural space that surrounds the dura mater or the spinal cord.
Epidural Anesthesia
70
An extensive conduction nerve block that is produced when a local anesthetic agent is introduced into the subarachnoid space at the lumbar level, usually between L4 and L5
Spinal Anesthesia
71
A form of anesthesia that involves the IV administration of sedatives or analgesic medications to reduce patient anxiety and control pain during diagnostic and therapeutic procedures
Moderate Sedation
72
Goal of Moderate Sedation
To reduce LOC to a moderate level to enable procedures to be performed while ensuring comfort and cooperation.
73
Characteristics of patients receiving moderate sedation
*Able to maintain patent airway
*Retains protective airway reflexes
*Responds to verbal and physical stimuli
74
A form of moderate sedation given by an anesthesiologist or CRNA who must be prepared and qualified to convert to general anesthesia if necessary
Monitored Anesthesia Care (MAC)
75
Indications of monitored anesthesia care
-Minor surgical procedures
-Critically ill patients who are unable to tolerate anesthesia without invasive monitoring and pharmacological support.
76
is the injection of a solution containing the anesthetic agent into the tissues at the planned incision site.

94
Principles of Intraoperative Positioning
-The patient should be in as comfortable position as possible, whether conscious or unconscious.
-The operative field must be adequately exposed
-An awkward anatomical position, undue pressure on a body part, or the use of stirrups or traction should not obstruct the vascular supply.
-Respiration should not be impeded by pressure of arms on chest or by a gown that constricts the neck or chest.
95
Goal of Care of Postoperative Phase
-Reestablishment of physiologic equilibrium
