, NUR 256
preoperative phase
period of time from when the decision for surgical intervention is made to when

spinal block
Injection of a local anesthetic agent directly into the spinal fluid in the spinal canal
to provide anesthesia for vaginal and cesarean births.
Malignant hyperthermia
rare, an inherited muscle disorder, a type of severe reaction that occurs to
particular medications used during general anesthesia, among those who are
susceptible. Symptoms include muscle rigidity, high fever, and a fast heart rate. (at
risk are those who have a lot of muscle mass) Dantrium sodium reverses this, can
occur after surgery
Second intention healing
A wound that is extensive and involves considerable tissue loss, and in which the
edges cannot be brought together heals in this manner.
