疼痛的存在是因为电冲动从“痛处”沿着一系列神经行走,通过骨髓内的阀门、并经过丘脑到达操纵思想、感觉和运动的大脑,沿途有几个“闸”能够调节疼痛或者象调整收音机量那样予以关小。人们可用中等量至大量的单一治法(如药物)以止痛,或者人们可用量至中量的复合治疗来达到同样或更多的舒适。在很多情况中,复合治法为患者提供较好的疼痛控制,在护理中起较积极的作用,副作用较少并且较少依赖他人。 Pain occurs because electric impulses travel from a “sore” through a series of nerves, through the valves in the bone marrow, and through the thalamus to the brain that manipulates thoughts, feelings, and movement, along with several “brakes” that regulate pain or adjust The volume of the radio should be turned off. One can achieve the same or more comfort with a moderate to large amount of monotherapy (such as medications) to relieve pain, or one that can be used in an amount that is moderate to moderate. In many cases, the composite approach provides better pain control for patients, plays a more active role in care, has fewer side effects and relies less on others.
