5 x 15
The success of a major operation depends in large part on the intensive post-
operative care of the patient Because of prolonged anesthesia and extensive
surgical trauma, the patient is often in worse shape after the operation than
before. The first few days after an operation are the most dangerous. During this
critical period, the patient is under constant surveillance in the post-anesthetic
recovery room or in an intensive care unit. Specially trained nurses and doctors
use electronic monitoring devices to detect deviations in the patient's vital
functions. The medical staff is also alert to signs of lung complications that
frequently follow major surgery. Venous stenosis, or the slow-up of blood low in
the veins
- a consequence of bed confinement
is prevented by exercising the
patient's limbs and varying his position in bed. Closed circuit television cameras
allow constant observation of the patient and monitoring devices linked with
computers sound a warning when dangerous complications occur, but the keen
senses of a skilled purse are still required to ensure the best after care of the sick
