目的研究负压封闭引流(VSD)联合过氧化氢灌洗在治疗骨折内固定术后感染的临床疗效。方法对17例骨折内固定术后感染患者,彻底清创后给予VSD敷料覆盖持续引流,并联合应用过氧化氢灌洗,待创面新鲜感染消退后采取直接缝合或皮瓣移植修复创面。结果 15例早期感染(2周)患者经1次VSD治疗后直接缝合或局部皮瓣转移修复创面成功,2例慢性感染患者(10周)经2次VSD治疗后关闭创面,感染复发,再次清创取出内固定物及VSD治疗,伤口愈合。随访13~25个月,术区无再发感染,骨折均获愈合。结论负压封闭引流联合过氧化氢灌洗是治疗骨折内固定术后早期感染的有效方法,可保留内固定物,缩短治疗周期,值得推广。 相似文献

In situations of stress, such as clinical trauma, starvation or prolonged, strenuous exercise, the concentration of glutamine in the blood is decreased, often substantially. In endurance athletes this decrease occurs concomitantly with relatively transient immunodepression. Glutamine is used as a fuel by some cells of the immune system. Provision of glutamine or a glutamine precursor, such as branched chain amino acids, has been seen to have a beneficial effect on gut function, on morbidity and mortality, and on some aspects of immune cell function in clinical studies. It has also been seen to decrease the self-reported incidence of illness in endurance athletes. So far, there is no firm evidence as to precisely which aspect of the immune system is affected by glutamine feeding during the transient immunodepression that occurs after prolonged, strenuous exercise. However, there is increasing evidence that neutrophils may be implicated. Other aspects of glutamine and glutamine supplementation are also addressed. 相似文献

The rates at which the paramagnetic compounds deoxyhemoglobin (Hb) and methemoglobin (MHb) form in vivo within an area of hemorrhage are unknown. The present experiment establishes the baseline concentrations and rates of change in paramagnetic hemoglobin concentrations, as well as the pH in normal heparinized and clotted human blood maintained in vitro at 37 degrees C under anaerobic conditions over 30 hours. There was a moderate increase in Hb concentration in normal heparinized blood (average increase was 15.5%, rate = 0.50%/hour) and a slight increase in MHb concentration in the heparinized blood and clots (average increase was 1.4%, rate = 0.044%/hour). A second experiment was done to verify the activity of the RBC systems responsible for maintaining the hemoglobin molecule in the reduced state. Conversion of MHb to Hb in these samples proceeded at a rate of 5.6%/hour. In a third experiment, blood from 11 normal subjects maintained at 4 degrees C 25 degrees C was analyzed for MHb concentration over the course of 28 days. The level of MHb formation remained in the range of normal for at least 11 days in all subjects. The authors conclude that at basal conditions created in vitro, the blood levels of both Hb and MHb remain at relatively low levels. Therefore, if the accumulation of Hb and/or MHb occurs in acute in vivo hematomas it must be driven by intrinsic tissue factors. 相似文献

The pathohistologic analysis of testis sections of 37 postpuberty patients with different types of cryptorchism is performed. The tissue samples were taken during orchiopehy, fixed in Bouin's solution and treated by the standard histologic techniques. The morphologic criteria are presented for identification of the presence of the so called carcinoma in situ cells found in two cases. Besides, in 13 patients rare, mainly single, atypical germinative cells were found in a smaller number of the seminiferous tubules. It has been concluded that the presence of carcinoma in situ cells in undescended testes of some patients and considering the simple way of sampling, lack of complications and high reliability of the diagnostic procedure, it is absolutely justified to take routine biopsy of testes during orchiopexy in each postpuberty and perhaps prepuberty patient. 相似文献

The scope for image-guided intervention in the chest is very wide and encompasses procedures in the heart, pulmonary and systemic vasculature, lungs and pleural cavities, airway, and esophagus. This review describes the most important procedures that are usually performed by radiologists. Percutaneous drainage is now the most common method of treating both empyemas and lung abscesses in children. Although most lung biopsies are carried out by other means, percutaneous biopsy and localization are important alternatives for the diagnosis of focal lung lesions. Esophageal strictures are common in children and are usually best treated by balloon dilatation. The use of retrievable or biodegradable stents has recently been introduced for refractory esophageal strictures. Similarly, balloon dilatation and stenting are now increasingly used in children with stenosis or extrinsic compression of the trachea or bronchi. 相似文献

Serum zinc in athletes in training 总被引:1,自引:0,他引:1

Serum zinc was determined using atomic absorption spectrophotometry in 160 training athletes (57 females) in the morning at rest. In 23.3% of the male and 43% of the female athletes, serum Zn was lower than the limit accepted for the normal range (75 microgram/dl or 11.5 mumol/l). The average serum Zn (96.7 +/- 12.6 microgram/dl) and the range of the values found in a control group of 15 young adult males did not differ from the accepted values in the literature. In 22 randomly selected male athletes, serum Zn fractions were determined using polyethylene glycol precipitation at pH 7.1; 22.2% of total Zn was bóund to alpha2-macroglobulin, the ratio being very close to 1 atom of metal per molecule of globulin. The possible reasons that may influence the serum Zn level in athletes are discussed with regard to the present knowledge in both exercise physiology and metabolism of zinc in man. 相似文献
