■ Needle placement is perpendicular to the skin:
■ Lower Leg (see Figure 19.11)
■ Anterior compartment: Needle entry point is 1 cm lateralto the
anterior border of the tibia.
■ Deep posterior compartment: Needle entry point is just posterior to
the medial border of the tibia.
■ Lateral compartment: Needle entry point is just anterior to the pos-
terior border of the fibula
■ Superficial posterior compartment: Needle entry point is 3–5 cm
on either side of a vertical line drawn down the middle of the calf
at the junction between the proximal and middle thirds of the
lower leg.
■ Forearm (see Figure 19.12)
■ Volar compartment: Needle entry point is just medial to the pal-
maris longus.
■ Dorsal compartment: Needle entry point is 1–2 cm lateral to the
posterior aspect of the ulna.
■ Pressures can be measured either with an arterial line pressure measure-
ment system or with a Stryker Intracompartmental pressure monitor system.
COMPLICATIONS
■ Infection, pain, inaccurate readings, exacerbation of compartment syndrome
by injection of fluid into compartment
INTERPRETATION OFRESULTS
■ Falsely elevated pressures may be a result of needles placed into tendons
or fascia, plugged catheters, or faulty electronic systems. Falsely low read-
ings may result from bubbles in the lines or transducer, plugged catheters,
or faulty electronic systems.
