factors to consider in giving anes
age
physical condition
type / location / duration of surgery
prev. anes hx
preferences
agents which interferes with nerve conduction and therapy administering loss of pain and sensation
Anesthetic Agents
types of anes
general
regional
local
Analgesia, amnesia, loss of consciousness
Loss of reflexes, muscle tone
AXN: blocking the pain stimulus at the cerebral cortex
general
inhaled general anesthesia
sevorane
isoflurane
desflurane
ethrane / enflurane
SIDE
iv anesthesia
pentothal Na
ketamine
diprivan HC
administration
to loss of
consciousness
Dizzy
Drowsy
Buzzing in his ears
unable to move his
extremities voluntarily
onset / stage of induction
loss of
consciousness to
the loss of eyelid
reflex
stage of excitement
loss of eyelid reflexes to the loss of most reflexes of the body and depression of vital function such as
respiratory effort.
Unconscious
Muscle are relaxed
reflexes are absent
RR is nearly normal
skin is pink
state of surgical anes
Reached when too
much anesthesia has been given wherein vital function are too depressed.
stage of danger
– anesthetic agents that directly applied to the skin or area to be desensitized - may be a solution, gel, cream or powder.
topical
it is the injection of anesthetic agent into the skin and subcutaneous tissues
It blocks only the peripheral nerves around the incision
infliltration
loss of sensation in a specific area of the body while the patient remain conscious
blocks the pain stimulus at its origin, along the afferent neurons, and spinal cord
regional anesthesia
injection of anesthetics into the subarachnoid space using the lumbar space ( L3 & L4 ) causing desensitization of the spinal nerves
spinal anes
example of spinal anes
sensorcaine
pontocaine
bupivacaine hcl
injecting anesthetic solution with use of epidural catheter into the epidural space
epidural anes
example of epidural
Morphine Sulfate
Bupivacaine HCl
Anesthetizes individual nerve or nerve plexuses
Used for hand and foot surgery
nerve block
This anesthetic is used in obstetrics and for surgery involving the perineum rectum, genitalia and upper parts of the thighs.
saddle block
a severe, life-threatening genetic reaction to certain anesthetic drugs, particularly volatile inhalation agents and the muscle relaxant succinylcholine, causing a sudden, excessive increase in muscle activity and body temperature
Malignant Hyperthermia
Maintain NPO for ___ hours. Note for drug reaction or side effects.
