Whitesides Technique is a cost-effective and invasive measure to measure the compartment pressure of the affected compartment.

Whitesides techniques
Whitesides technique

Manometer and limb should be at the same level

Components used in the Whitesides technique

  • Three-way stop clock – Open
  • The saline meniscus in the proximal tube
  • Insert needle
  • Increase pressure in the syringe until the meniscus moves
  • Read pressure

The extremity to be measured in cleaned and sterility prepped

Sterile saline is drawn into a 20 ml syringe while attached to a 3-way stopcock

A single intravenous extension tube is attached to the stop clock and a second gauge needle is attached to its other end

3rd unused portion of the stopcock is closed off temporarily

An 18-gauge needle at the end of the extension tube attached to the stopcock is inserted into a bottle of saline

Saline is then aspirated without the bubbles into approximately half the length of the extension tube

3- way stop clock is turned to close off this tube so that the saline is not lost during the transfer of the needle

The second extension tube is then connected to the 3-way stop clock at its remaining open part and its other end is connected to the manometer

Saline containing needle is then inserted into the muscle of the extremity to be tested

The stopcock is then turned so that the syringe is open to both extension tubes, forming a T- connection with a free column of air extending from behind the column of saline into the syringe as well as into the manometer

Pressure is increased in the system gradually by slowly depressing the plunger of the syringe while watching the column of the saline

As the plunger is depressed, the saline meniscus will be altered from the convex configuration to a flat configuration (When air pressure in the system is equal to interstitial pressure in patient-examined tissue)

The manometer reading at this brace in mmHg

Precaution while using the Whitesides technique

Not to depress the syringe plunger too rapidly

Placing the needle in the tendon
