If some one has come bk from surgery and had anesthesia what are the two high risk patients the nurse should really look out for?

-Those with liver and kidney disease.

Induced state of partial or total loss of sensation, occurring with or without loss of consciousness. Used to block nerve impulse transmission, suppress reflexes, promote muscle relaxation, and in some instances achieve a controlled level of unconsciousness.

Anesthesia

-Reversible loss of consciousness.
-State can be achieved by a single agent or a combination of agents.
-Central nervous system is depressed resulting in analgesia, amnesia and unconsciousness with loss of muscle tone and reflexes.
-With this the nurse needs to consider emotional/psychological effects which include the fear of being put to sleep.

General Anesthesia

Name the two types of General anesthesia and info about them.

1. Inhalation-Intake and excretion of anesthetic gas or vapor to the lungs through a mask.
2. Intravenous Injection- injected through an IV line disposed in the blood.

How long does recovery take when given general anesthesia?

Recovery depends on type of agent, length of time client is anesthetized and if a reversal agent is used.

What are possible responses to general anesthesia?

Retching, vomiting, restlessness and changes in the ability to control body temperature.

What are some interventions we might use when some one went through general aneshthesia?

Suction equipment, warmth and O2.

***************test question*******************
What is the biggest complication from general anesthesia?

Malignant hyperthermia

*************test question********************
This is the biggest complication from general anesthesia.
Marked by a rapid rise in body temperature, increase in serum calcium and potassium, signs of increased muscle metabolism (muscle proteins detected in the urine) and rigidity. Can be life-threatening.

2. Overdose
3. Complications of specific anesthetic agents.
4. Unrecognized hypoventilation.
