midclavicular line

Etymology: AS, midd + L, clavicula, little key, linea, line
(in anatomy) an imaginary line that extends downward over the trunk from the midpoint of the clavicle, dividing each side of the anterior chest into two parts. The left midclavicular line is an important marker in describing the location of various cardiac phenomena, including the point of maximum impulse.

mid·cla·vic·u·lar line

(mid'klă-vik'yū-lăr līn) [TA]
An imaginary vertical division on the anterior surface of the body, passing through the midpoint of the clavicle.
Synonym(s): midclavicular plane [TA] .

midclavicular line

An imaginary median line used to describe locations on the trunk. At its top, it passes through the midpoint of the clavicle, and on a male, it runs just medial to the nipple. It crosses the costal margin near the end of the 9th costal cartilage and it extends to the thigh, passing through the fold of the groin halfway between the anterior superior iliac spine and the symphysis pubis. At one point, the milk line (mammary line) intersects the midclavicular line.

I palpate the edge of the ribs at the midclavicular line at the costal margin and carefully slide a #11 blade right along the lowermost rib to create an incision only large enough to accommodate a 2-mm scope.
Once pneumoperitoneum pressure of 20 mm Hg is established, insert a 5-mm trocar perpendicular to the abdominal wall, 3 cm below the ribs, midway between the midclavicular line and the anterior axillary line.
After establishing the pneumoperitoneum by Veress needle or by Hasson technique, three to four trocars are usually placed between the midclavicular line and anterior axillary line 2 cm caudally to the costal margin.

The highest level of sensory block was sensed by pinprick method in caudal to cephalic direction every two minute, after the procedure of subarachnoid block was complete and the time taken to achieve absence of pinprick response at T 10 level in midclavicular line was taken as onset of sensory block.
The most preffered site for initial access is the palmer's point-a point 3 cm below the left costal margin in midclavicular line, as one is least likely to encounter intraabdominal adhesions at this point.
