Recently in the clinic, we found that many patients have problems in making and using ice packs. The wrong choice of ice packs will not only affect the ice effect, delay recovery, but even have safety risks. Now I would like to introduce a scientific method of making ice packs for icing. In fact, ice in many disciplines of medical applications, such as shock patients using ice caps to protect brain tissue, fever patients through the axillary ice bag physical cooling, etc.. This is the most widely used ice bags in sports medicine, due to the different purposes of treatment, ice packs when the choice of ice bags and ice methods are also very different. Suitable ice bags and the combination of scientific ice, in order to achieve the best and safest ice effect, in fact, we can do this ourselves. 1, how to choose an ice pack Now you can buy a variety of ice packs on the market, can be divided into two kinds, containing freezing medium and does not contain freezing medium. Containing media similar to the ice box in the car refrigerator, its cold capacity can reach six times the same volume of ice. This ice bag is easy to use and efficient in refrigeration and preservation, but because the initial surface temperature is too low and not constant, the effect is not good when used for limb icing, and even unsafe, sometimes causing frostbite. In contrast, the effect of ice bags without media is better, the use of ice and water mixture as a medium, the surface temperature of this ice bag is constant, the role of lasting. But I still recommend the use of homemade ice bags, not only because of the cheap (almost zero cost), but more importantly, the safety and effectiveness of homemade ice bags are guaranteed, and even have the advantages of the above two ice bags can not compare (later). Hospitalized patients will see our wards have special ice bags and ice machine, in fact, when you go home, you can do the best ice bags. (Professional medical ice machine) 2, how to make your own ice bags Materials: medium size plastic bags (supermarket to buy, two at a time), ice (refrigerator ice compartment homemade, or to the KFC margin), tap water. Ice bag steps are simple, but there are a few notes: (1) generally use 1 part ice + 2 parts water, ice and water mix accounted for 1/2 of the capacity of the ice bag can be; (2) sealing, the air above the water first, in the position near the mouth of the bag knot (A), not close to the water knot (B), and not half a bag of air half a bag of water (C). This has three advantages: the ice bag will not be bulging, not easy to slip when placed; increase the contact area of the ice bag and skin; ice bag without air, so the ice will not cause the surrounding is the middle of the ice water is air, so that the ice is even; (3) after sealing and tying, and then outside a layer of plastic bags, plastic bags of varying quality, make a watery Jinshan wretched, especially the affected person has not yet removed the stitches, but also contaminated wound. 3, the timing of icing acute injury: icing to be carried out in the first time the injury, the earlier icing pain and swelling effect is better; in the next 2 to 3 days can also be iced, until the swelling subsides. If the first few days after the injury is not iced, the injured area is still painful and swollen, can also be relieved by icing, but the effect to be discounted. Although more and more people know that the saying “ice within 24 hours and heat after 24 hours” is not true, we often see patients with swollen feet like steamed buns due to heat application during the acute period, and the swelling will be slow to go down later. Post-operative rehabilitation: Ice therapy is essential for post-operative rehabilitation in sports medicine. In the case of the knee joint, for example, icing can reduce the pain of leg bending exercises, reduce tissue congestion and edema around the knee joint, and reduce the occurrence of ossifying myositis. Ice is generally carried out as soon as possible after rehabilitation exercises, so be prepared before the exercise ice bag, for the joint swelling, pain is more obvious patients, leg bending exercises can also be used between the ice to reduce swelling, pain. 4, the method of ice pack ice bag with ice and water mixture as a medium, the room temperature should be appropriate to put a little more ice, because the high room temperature ice melts quickly, if the ice soon all melted into water, the temperature of the surface of the ice bag will begin to rise, the second half of the ice effect will be affected. The advantage of homemade ice pack is to use a transparent plastic bag, you can always see the ice and water mixture melting when icing. The first time you use an ice pack, you can put a thin towel on the ice part, do not wrap the ice pack, ice is generally maintained for 15 to 20 minutes, so it is best to let the ice melt away in about 20 minutes. Used a few times will know how much ice is most appropriate to put, so that neither waste to ensure the ice effect. After mastering the rule, you can also use thin towels wrapped in ice packs for ice. The frequency and number of ice packs can be increased to once every 2 to 3 hours if necessary, depending on your actual situation. For parts with bony prominence ice (such as fibular tuberosity, tibial tuberosity, femoral medial epicondyle, etc.), ice time should be strictly controlled, and it is best not to directly touch the ice pack to the skin to avoid frostbite. ”Details determine success or failure”, scientific and effective icing, can minimize pain, promote the recovery process, reduce unnecessary trouble. I wish you all a speedy return from injury!
