股骨颈骨折、股骨粗隆骨折患者常规行下肢皮肤牵引术,而持续牵引易致足跟部发生压疮,患者常因足跟部疼痛不适而拒绝牵引,或因足跟发生压疮而影响治疗效果。一般在牵引带远端包裹毛巾或使用棉垫,由于牵拉毛巾、棉垫易产生皱褶,持续摩擦导致不适,难以有效保持下肢牵引制动及预防足部压疮的要求。为解决这一矛盾,众多学者做了大量研究,临床研究认为,凉液垫、水垫及浴巾等应用于下肢牵引的患者,取材方便、价格便宜,可有效
Patients with femoral neck fractures and femur trochanteric fractures are routinely underwent lower extremity skin traction while continual traction tends to cause pressure ulcers in the heel and heel. Patients often refuse traction due to heel or foot pain discomfort or hemorrhagic pressure ulcers in the heel effect. Usually in the remote traction band wrapped towels or use cotton pad, due to pull the towel, pad prone to wrinkles, friction caused by continuous discomfort, it is difficult to effectively maintain the lower limb traction and foot pressure ulcer prevention requirements. To solve this contradiction, many scholars have done a lot of research, clinical studies believe that cold liquid pad, water cushion and towel applied to patients with lower limb traction, easy access, cheap, effective
