ABSTRACT
Objective To investigate the effect of self-designed closed negative pressure drainage combined with sponge dressings on refractory wounds.Methods Sixty patients with phase III-IV pressure ulcers were randomly divided into experiment group and control group in equal number.The self-designed closed negative pressure drainage combined with sponge dressing was applied in the experiment group and in the control group the conventional dressings were used.The two groups were compared in terms of hyperplasia of fresh granulation tissue,time for filling the defect and the healing time and the medical expense.Results Compared to the control group,the time for hyperplasia of fresh granulation tissue,the time for filling the defect and the healing time in the experiment group were all significantly shorter,and the medical expense of the experiment group was significantly less(all P<0.01). Conclusion The self-designed closed negative pressure drainage combined with sponge dressings in the treatment of phase III-IV refractory pressure ulcers may effectively shorten the healing time,improve the curative effects and reduce the economic burden of patients.
ABSTRACT
BACKGROUND: The osteoarthritis (OA) is attributed to Gubi of TCM,which is mainly caused by liver and kidney deficiency, deficiency and damage of both qi and blood and wind-cold-damp pathogen. Kidney-deficiency with coagulating-coldness syndrome is very common.OBJECTIVE: To explore the clinical effect of the treatment of OA by invigorating the kidney, dispelling the cold and activating collaterals.DESIGN: Randomized controlled clinical study.SETTING: Department of Traditional Chinese Medicine, Dongguan Shilong People's Hospital of Guangdong Province.PARTICIPANTS: Eighty-eight inpatients and outpatients who were most possible to benefit from the experiment were selected as the subjects from the Department of Rheumatism and the Clinic of Orthopedics from June 2005 to July 2006. All subjects were randomized into the experimental group (n=44) including 21 males and 23 females, whose ages ranged 42-70 years, and their average age was (62±8) years and the average course of diseases was (34±18) months, and the control group (n=44), including 24 males and 20 females, whose ages ranged 40-69 years, and their average age was (61±7) years and the average course of diseases was (34±16)months.METHODS: Patients in the experimental group were treated with Bushen Quhan Tongluo herbs by orally taken or externally washing. The prescription of Bushen Quhan Tongluo: Hutaorou (12 g), Buguzhi (12 g), Chaoduzhong (12 g), Shudi (15 g), Dahuixiang (9 g), Luoshiteng (15 g),Zhichuanwu (9 g), Sanqi (6 g), Wugong (3 g), Jixieteng (15 g). The prescription for external washing: Tuogucao (40 g), Danggui (15 g), Sumu (15 g),Shengdahuang (15 g), Shengnanxing (10 g), Ruxiang (10 g), Meyao (10 g),Bingpian (3 g). (Orally taken: The medicine shall be taken with water of 37 ℃ one dose a day. External washing: The medicine that dissolved in 500 mL of 100 ℃ boiled water was adopted to wash both knees while the temperature down to 35 ℃ one dose upon a time and twice a day). Patients in the control group were given sulfated glucosamine (Weiguli Capsule.Each capsule contains 314 mg of sulfated glucosamine crystal, which is equal to 250 mg of sulfated glucosamine) two capsules a time and 3 times a day as well as piroxicam (Yantong Xikang Pill) once a day and 20 mg each time. Patients in both groups were administrated for 12 weeks. Referring to the Western Ontario and McMaster Universities (WOMAC) OA index and the clinical effect criterion of OA, the curative effect was compared between the two groups.MAIN OUTCOME MEASURES: WOMAC pain score, stiffness score,physiological function score, total score and the clinical effect.RESULTS: A total of 88 patients were involved in the analysis of results.joint stiffness index, physiological function index and the total index after the treatment in both the experimental group and the control group than those before the treatment (The experimental group: 4.95±2.46,11.39±4. 10;0.70±0.88,1.57± 1.42; 13.16±5.71,31.16± 10.08; 18.82±7.96,44.11 ± 13.29;Control group: 6.64±1.81,11.59±3.07 ;0.68±0.86,1.52±1.34; 14.25±3.99,pain index in the experimental group after the treatment was lower than that in thecontrol group, and the difference was remarkable (P ＜ 0.05),The total effective rate was 95.5% in the control group and it was 93.2% in the experimental group, and there was no marked difference between the epigastric discomfort in the control group, while there was no haematemesis, hemafecia or aggregation due to continuous administration. No adverse effect was found in the experimental group.CONCLUSION: Satisfying effect can be achieved in the treatment of OA of cold coagulation due to kidney deficiency by invigorating the kidney,dispelling the cold and activating the collaterals, moreover, the effect of relieving pain is especially excellent.
