SHOCK Learning Objective: When you finish this chapter, you will be able to— Recognize  the  symptoms,  prevention,  and treatment of shock. If you’ve ever hit your finger with a hammer and felt—in  addition  to  the  pain—weak,  dizzy,  and nauseous,  then  you  have  experienced  a  mild  form  of shock.   In   this   case,   the   symptoms   appeared immediately after the injury, but they may not show up for several hours. Shock is a condition in which blood circulation is seriously disturbed. Crushed or fractured bones, burns, prolonged  bleeding,  and  asphyxia  all  cause  shock. Shock may be slight or it may be severe enough to cause death. Because all traumatic injuries result in some form of shock, you should learn its symptoms and know how to treat the victim. HOW TO RECOGNIZE SHOCK A person who is going into shock may show quite a few signs or symptoms, some of which are indicated in figure  14-14,  and  are  discussed  in  the  following paragraphs.  Remember,  that  signs  of  shock  don’t always appear at the time of the injury; and, in many very  serious  cases,  symptoms  may  not  appear  until hours later. The symptoms of a person suffering from shock are caused, directly or indirectly, by the disturbance of the circulation of the blood. Symptoms of shock include the following: The pulse is weak and rapid. Breathing  is  likely  to  be  shallow,  rapid,  and irregular,  because  the  poor  circulation  of  the  blood affects the breathing center in the brain. The temperature near the surface of the body is lowered  because  of  the  poor  blood  flow;  so  the  face, arms, and legs feel cold to the touch. Sweating is likely to be very noticeable. A  person  in  shock  is  usually  very  pale,  but,  in some cases, the skin may have a bluish or reddish color. In the case of victims with dark skin, you may have to rely primarily on the color of the mucous membranes on the inside of the mouth or under the eyelid or under the nail bed. A person in or going into shock has a bluish color to these membranes instead of a healthy pink. 14-14 Student Notes: Figure 14-14.—Symptoms of shock.
