Application of the self-made 10％ sodium chloride solution pad ice packs in early local soft tissue injury patients

Abstract

Objective To explore the effect of self-made 10％ sodium chloride solution pad ice packs on the patients with local soft tissue injury in early time.Methods Totals of 62 cases with lower limb soft tissue injury were selected and randomly divided into experimental group ( n =32 ) that received the cold compress treatment by homemade 10％ sodium chloride solution pad ice packs,and control group( n =30) that received the cold compress treatment by water pad ice packs.Then,0,0.5,1.5,2 h later,the internal temperature,the temperature between the body surface and ice bag,hardness,the surface of contact surface size,and patients' satisfaction of two groups were observed.Results In the experimental group,the initial temperature of 10％sodium chloride solution pad ice packs was ( - 18.38 ±0.81 ) ℃,temperature between ice bag and body surface was 18℃ during cold compress,half an hour later,the temperature of inside ice bag was ( -9.73 ± 0.54)℃.After one hour in the room,the second cold compress,internal temperature was ( - 2.55 ± 1.66) ℃ and the temperature between ice bag and the surface was about 22 ℃,the end of ice internal temperature was (8.5 ±1.81 )℃.Hardness of first and secondary cold compress was small,the area size of skin contact with ice was about 72％.In the control goup,for the water cotton pad ice bags were so hardness that early thermometers were not inserted and temperature can not accurate measured.And the area of skin contact with ice was 29％.Significant differences were found in the contact area between two groups in different time (t =49.32,49.32,49.32,39.64,respectively; P ＜ 0.05 ).There was no significant difference in the pain degree of patients between two groups,while after 48 h cold compress,pain rating index and the swelling score of experimental group was significantly lower than that of control group(x2 =0.017,P ＜0.05).Patients' satisfaction of experimental group was significantly higher than that of control group ( x2 =4.4,P ＜ 0.05 ).Condusions Appling the selfmade 10％ sodium chloride solution pad ice packs,for the temperature between ice bag and the surface was higher than the skin freezing temperature( -5 ℃ ) and below the basal body temperature,which can reach the objective with no cause frostbite,it has large contact area,easy fixing and shaping,and good for patients with local soft tissue injury in early stage.
