林区野外作业,腕躁关节扭挫伤很常见。如处理不当,会反复扭伤,严重者可导致患处长期肿胀、疼痛,易发展为创伤性关节炎。关节扭挫伤发生后有人采取按揉或热敷措施,以期消肿止痛。也有人置疼痛于不顾,坚持活动关节。其实这样作都是错误的,因为扭挫伤后,局部毛细血管破裂出血,损伤组织细胞挫灭渗出,血液及组织液淤滞形成肿胀。若在此时热敷,就会使血管扩张,增加出血;若按揉也会减慢组织自身凝血过程,同时增加了出血和加剧了肿胀,从而延长了治疗过程。
Field work in the forest, wrist mania joint contusion is common. If handled improperly, will repeatedly sprained, severe cases can cause long-term swelling of the affected area, pain, easy to develop into traumatic arthritis. Some people take after the joint contusion contusion or hot compressing measures to reduce swelling and pain. Some people ignored the pain at the same time, adhere to the activities of joints. In fact, this is wrong, because the contusion, the local capillary rupture of bleeding, tissue damage caused by exudate cells, blood and tissue fluid stasis swelling. If the heat at this time, it will cause the blood vessels to dilate, increasing bleeding; if rub will also slow down the process of tissue coagulation itself, while increasing bleeding and aggravate the swelling, thus extending the course of treatment.
