A service member experiencing combat stress reaction is having a crisis, and there are two basic elements to that crisis working in opposite directions. On the one hand, the service member is driven by a strong desire to seek safety and to get out of an intolerable environment. On the other hand, the service member does not want to let their comrades down. They want to return to their unit. If a service member starts to lose contact with their unit when he enters treatment, the impulse to get out of the war and return to safety takes over. They feel that theyve failed their comrades who have already rejected them as unworthy. The potential is for the service member to become more and more emotionally invested in keeping their symptoms so they can stay in a safe environment. Much of this is done outside the service members conscious awareness, but the result is the same. The more out of touch the service member is with their unit, the less likely they will recover. They are more likely to develop a chronic psychiatric illness and get evacuated from the war. Simplicity
Treatment is kept simple. CSC is not therapy. Psychotherapy is not done. The goal is to rapidly restore the service members coping skills so that he functions and returns to duty again. Sleep, food, water, hygiene, encouragement, work details, and confidence-restoring talk are often all that is needed to restore a service member to full operational readiness.
Etacrynic acid (INN) or ethacrynic acid (USAN), trade name Edecrin, is a loop diuretic used to treat high blood pressure and the swelling caused by diseases like congestive heart failure, liver failure, and kidney failure. A con with etacyrnic acid compared to the other loop diuretic drugs such as furosemide is that it has a significantly steep dose-response curve, which means the drugs dosing is very important as small variance in dose can cause a significant difference in the biological response. Unlike the other loop diuretics, etacrynic acid is not a sulfonamide and thus use is not contraindicated in those with sulfa allergies. If a patient with sulfa allergies is in need of a loop diuretic, it is more likely for the physician to prescribe etacyrnic acid for this reason. Structural features
Ethacrynic acid is a phenoxyacetic acid derivative, which means it contains a ketone group and a methylene group. Medical use
Ethacrynic acid is a diuretic that is used to treat edema when a stronger agent is required. It is available as a pill or injected form. The pill is used to treat edema associated with congestive heart failure, cirrhosis and renal disease, accumulation of liquid in the belly associated with cancer or edema,  and management of hospitalized children with congenital heart disease or nephrotic syndrome. The injected form is used to rapidly remove water from the body when needed – for example in acute pulmonary edema – or when a person cannot take the medicine in pill form.
