Objective:To explore the effect of modified multifunctional dressing bag with glauber's salt for relieving swelling and pain in early patients with limb fracture.Methods:A total of 111 patients with limb fracture in Tongde Hospital of Zhejiang Province were divided into two groups according to the admission time. The control group consisted of 53 patients with limbs fracture using common mirabilite bag with glauber′s salt and ice bag for external application admitted from January to August 2018, and the observation group consisted of 58 patients with limbs fracture using modified multifunctional dressing bag with glauber′s salt admitted from September 2018 to January 2020. The degree of pain, the time of appearance of dermatoglyphia, the cases of severe swelling, waiting time for operation, compliance and comfort of the patients were observed within 72 hours after injury.Results:The degree of pain, the time of appearance of dermatoglyphia, the waiting time, the cases of severe swelling for surgery in the observation group were (1.8±0.7) points, (4.5±1.2) days, (5.7±1.2) days,1 case, respectively, which were all lower than those in the control group (2.2±0.8) points, (6.0±1.5) days, (6.5±1.4) days, 19 cases, the differences between the two groups were statistically significant ( t values were -2.6,-5.6,-3.3, &chi;2 value was 21.8, all P<0.05). The total compliance rate in the observation group was 82.76% (48/58), higher than that in the control group 56.60% (30/53), the differences were statistically significant ( &chi;2 value was 9.34, P<0.05). The comfort of the observation group was 82.76% (48/58), significantly higher than that of the control group 3.77% (2/53), the difference was statistically significant ( &chi;2 value was 69.8, P<0.05). Conclusions:The modified multifunctional dressing bag with glauber′s salt can reduce the swelling of limbs, reduce the appearance of skin blisters, stop bleeding and pain, and shorten the waiting time for operation, at the same time, it improves the compliance and comfort of the patients.
