all the way to the left colic flexure, goes first to
the
marginal
lymph nodes and then to the lymph node stations located
along the right colic arteries all the way to their point of
origin from the superior mesenteric artery. So the
lymphatic
hilus of the right and transverse colon is represented
by lymph
nodes placed at the root of the middle colic artery. The
lymph
drainage system of the descending
rectum goes first to the marginal
colon, sigmoid colon, and
lymph nodes and then to the
»
lymph nodes located at the root of the inferior
mesenteric
artery, which represents the lymphatic hilus of the left half
of the colon. The next emplacements of lymphatic drainage are
the lymph node stations
located on either side and in front of
the aorta and inferior vena
cava.
•Tumors of the anus and anal canal, as they diffuse
along the lymphatics, metastasize also into the inguinal lymph
nodes.

ACUTE RESPIRATORY
FAILURE
(From CURRENT THERAPY, 1975, section 2, p. 86)
Respiratory
failure results from impairment of gas
exchange
between alveolar air and blood. When the impairment is
severe, gas exchange will be inadequate to meet the patients'
needs; this leads to carbon dioxide retention, reflected by
high partial pressure of carbon dioxide in the arterial blood
and hypoxemia when the patient is breathing
room air. Respiratory
failure may be either acute or
chronic.
