Abstract

|
|
A compartment syndrome is defined as a condition in which the circulation and function of tissue within a closed space are compromised by increased pressure in that space. The muscles and nerves of the extremities are closed in fascial spaces, therefore susceptible to this condition. That condition is a signficant clinical problem, causing major functional losses following a wide variety of traumatic, vascular, hematologic, renal, and iatrogenic conditions.
In many patients, the diagnosis of a compartment syndrome may be difficult because pain itself, the most common symptom, is nonspecific particularly when it occurs in a clinical setting where severe pain is expected. Other signs and symptoms are also frequently nonspecific and therefore surgeons are prone to delay definite treatment. If a fasciotomy is done as complete paralysis has occured, the permanant functional damage already may be significant. Particularly in the upper extremity, any functional residual deficit may cause severe consequences.
The forearm tissue pressure was measured with tourniquet and analysed in 56 surgical cases (ranging from 19 to 63 years old) under general anesthesia from January to June, 1980. The following results were obtained.
1. The tissue pressure was significantly higher in patients applying tourniquet after venous drainage at 90 minutes.
2. The longer the time of applying tourniquet, the higher the valu of tissue pressure was obtained, whether venous blood was drained or not.
3. The tissue pressure was slight higher in female than that of male, the difference was not significant statistically.
4. After removal of tourniquet, tissue pressure was returned to normal level within 10 minutes.
5. The highest tissue pressure level during 90 minutes of tourniquet application was far under the critical level (20.4mmHg at 90 minutes) and therefore it appeared to be safe that the tourniquet pressure inflated up to 300mmHg during at least 90minutes in the upper arm.
