Anesthesia |
The loss of the ability to feel pain is open from the administration of an anesthetic drug |
|
|
Balanced anesthesia |
The practice of using combinations of different drug classes rather than a single drug to produce anesthesia |
|
|
General anesthesia |
A drug-induced state in which the CNS nerve impulses are altered to reduce pain and other Sensations. It involves complete loss of consciousness and depression of respiratory drive |
|
|
Local anesthesia |
Is drug-induced state in which is peripheral or spinal nerve impulses are altered to reduce or eliminate pain and other Sensations |
|
|
Malignant hyperthermia |
A genetically linked major adverse reaction to general anesthesia characterized by rapid rise and body temperature as well as tachycardia, tachypnea, and sweating |
|
|
Moderate sedation (conscious sedation) |
Milder form of general anesthesia that causes partial or complete loss of consciousness but doesn't reduce normal respiratory drive |
|
|
Monitored anesthesia care |
Planned procedure in which the patient goes under local anesthesia along with sedation and analgesia |
|
|
Cardiac and pulmonary functions are the usually the last to be interrupted because |
They are controlled by the medulla of the brainstem. |
|
|
Contraindications |
Contraindications may include pregnancy, narrow angle glaucoma, acute porphyria, and known susceptibility to malignant hyperthermia |
|
|
Ketamine |
Unique drugs with multiple properties. Used for general anesthesia and sedation. Used in ER for setting bones. Binds to opioid receptors and NMDA receptors. Low incidence of depression of cardiovascular, respiratory, and bowel. Has bronchodialating factors- good for asthma. Hallucinations which are less likely to occur with benzos. |
|
|
Nitrous Oxide |
Laughing gas. Inhaled general anesthetic. Weakest of anesthetics. Used in dental procedures. Increases risk of PONV after 1 hour. |
|
|
Most common drugs for moderate sedation |
Short-acting benzodiazepine (midozolam) and short acting opioid (fentanyl or morphine) |
|
|
Succinylcholine |
Depolarizing NMBD. Sinilar to ACh and produces same effects. Slower metabolism; repolarization cannot occur. Tendency to cause muscle fasciculations |
