四种生长激素对重度烧伤患者血糖的影响

明显增多(P＜0.01);在应用同种生长激素的情况下,使用剂量为0.2U·kg-1·d-1的治疗组比使用剂量为0.15 U·kg-1·d-1的治疗组患者平均胰岛素用量也明显增多(P＜0.01).除空白对照组外,其他各治疗组停用生长激素后血糖均恢复到正常值范围之内且不需要胰岛素控制,恢复至正常的时间差异无统计学意义(P＞0.05).结论 重度烧伤患者血糖水平与生长激素的使用剂量呈正相关;不同技术生产的生长激素对重度烧伤患者血糖影响基本相同;规范应用生长激素进行治疗,不会导致糖尿病.

不同敷料组合对烧伤患者供皮区创面微环境的影响

Objective To investigate the effect of dressing materials in various combinations on bum wound microenvironment and healing condition. Methods Two hundred donor sites with wounds of 0.3 mm in depth in 186 burn patients, who needed skingrafting and admitted to our ward were enrolled in study, and they were divided into A ( with dressing composed of aiginate + cotton pad for donor area), B ( with dressing composed of vaseline gauze + cotton pad for donor area) , C (with dressing composed of algi-nate+ foam dressing for donor area), D ( with dressing composed of vaseline gauze + foam dressing for donor area) groups according to random table method. Effect of dressings on wound evaporation and pH value were observed. Bacterial colonization, degree of pain complained by patients after dressing change, and wound healing time in each group were compared. Results One hundred and eighty-four patients complied with the study, while 2 patients were excluded due to untimely falling-off of the dressing. Wound evaporaton in respectively, among them B group showed optimal effect of keeping humidity (P<0.01). Wound pH value in A, B, C, D groups was 7.22±0.06, 7.41±0.03, 7.05±0.03, 7.34±0.06, respectively, among them it was highest in B group. The positive rate of bacteria in D group was highest (22.4%), and lowest in C group (4.0%). Pain was lightest in C group (score was 0.98±0.12), and most serious in B group ( score was 8.14±0.82). The shortest wound healing time was seen in C group (6.7±0.8 d) , and longest in D group (15.6±3.5 d). Conclusions Application of various dressings on similar wounds can pro-duce different wound microenvironment, which is closely related to wound healing time. Compared with pH value, humidity is the more important factor for wound healing.

早期负压封闭引流治疗深Ⅱ度烧伤创面的临床疗效评价

Objective To evaluate the clinical curative effect of applying vaccum sealing drainage (VSD) therapy in treating deep partial-thickness burn wound at the initial stage prospectively, and to provide the basis for its clinical application. Methods Twenty-two patients with about 10% TBSA burn of the lower limbs, and in which partial-thickness wound exceeded 1% TBSA in each limb, were admitted to our hospital within 3 hours after burn from May 2009 to March 2010. Wounds in each patient were divided into VSD treatment group (treated with VSD therapy) and control group (treated with 10 g/L silver sulfadia-zine cream) based on the principles of symmetry of location, identical deepness, and similarity in size etc. The amount of water evaporation, the swelling intensity, the status of bacterial colonization, the degree of pain, the healing time, and the quality of healing of wounds in 2 groups were observed and compared. Data were processed with t test and rank-sum test. Results The observation was completed in 21 patients. All of the wounds were treated within 4 hours post burn (PBH). The amount of water evaporation of the normal skin and burn wounds before dressing coverage in VSD treatment group was respectively close to that in control group (with t value respectively 1.310, - 0. 911, P values all above 0.05) ; the amount of water evaporation on the surface of dressing in VSD treatment group [(44. 3 ±3.9) mL·h-1·m-2] was less than that in control group [(66.1 ±6.4) mL · h-1· m-2, t = -11.39, P <0.01]. In VSD treatment group, the circumference of proximal thigh increased (3.48 ±0.35) and (2.51 ±0.21) cm on post burn day (PBD) 3 , 7 as compared with that on PBH 5 , which was respectively smaller than that [(8.02 ± 0.41) , (3. 99 ± 0. 32) cm] in control group (with t value respectively 4. 110, 3. 569, P values all below 0. 01). Positive bacteria' culture rate on PBD 10 of each group was respectively lower than that at admission (with Z value respectively -3.220, -3.870, P values all below 0. 01) , and there was no significant statistical difference between 2 groups at admission or on PBD 10 (with Z value respectively - 0. 894, 0.000, P values all above 0.05). The wound surface in VSD treatment group was weak acidic (pH value 7. 12 ±0.06) on PBD 10,and it was neutral (pH value 7.41 ±0. 13) in control group. The wound pain degree in control group on PBD 1,3,7 was respectively higher than that in VSD treatment group (with t value respectively - 16. 132, -21.230, -16.453, P values all below 0.01). There was no significant statistical difference between 2 groups in healing time of wounds (t =1. 186, P >0.05). The healing quality of wounds in VSD treatment group (100. 00% , 100. 00%) 2 or 3 months after burn was better than that in control group (19. 05% , 85. 71%) (with Z value respectively -11.638, -3. 870, P values all below 0.01). Conclusions Early application of VSD therapy cannot expedite the healing process of deep partial-thickness burn wounds, but it can improve the healing quality. It is one of the effective methods to deal with deep partial-thickness burn wounds, which is worthy of clinical attention and further research.     

早期负压封闭引流治疗深Ⅱ度烧伤创面的临床疗效评价

目的 前瞻性评价早期VSD治疗深Ⅱ度烧伤创面的临床疗效,为其临床应用提供依据.方法 选择笔者单位2009年5月-2010年3月收治的双下肢烧伤后3 h内入院、总面积小于10%且各下肢深Ⅱ度面积大于1%TBSA的患者22例.依照部位对称、深度相同、面积相近等同体对照原则,将每例患者创面分为VSD治疗组(应用VSD治疗)与对照组(应用10 g/L磺胺嘧啶银霜换药).观察2组患者创面的水分蒸发量、肿胀程度、细菌定植情况、疼痛程度、愈合时间及愈合质量并进行比较分析.数据行t检验与秩和检验.结果 21例患者完成试验,均在伤后4 h内完成创面处理.VSD治疗组正常皮肤及覆盖敷料前创面的水分蒸发量与对照组相近(t值分别为1.310、-0.911,P值均大于0.05);创面覆盖敷料2 h后,敷料表面的水分蒸发量[(44.3±3.9)mL·h-1·m-2]明显少于对照组[(66.1±6.4)mL·h-1·m-2,t=-11.39,P<0.01].伤后3、7 d,VSD治疗组大腿周径较伤后5 h分别增加了(3.48±0.35)、(2.51±0.21)cm,明显小于对照组的(8.02±0.41)、(3.99±0.32)cm(t值分别为4.110、3.569,P值均小于0.01).2组创面入院时及伤后10 d细菌培养阳性率组间比较,差异均无统计学意义(Z值分别为-0.894、0.000,P值均大于0.05);2组伤后10 d细菌培养阳性率均较各组入院时显著降低(Z值分别为-3.220、-3.870,P值均小于0.01).VSD治疗组创面伤后10 d的pH值(7.12±0.06)呈现弱酸性,对照组(7.41±0.13)则为中性.VSD治疗组伤后1、3、7 d创面疼痛程度轻于对照组(t值分别为-16.132、-21.230、-16.453,P值均小于0.01).2组创面愈合时间比较,差异无统计学意义(t=1.186,P>0.05).伤后2、3个月VSD治疗组创面愈合质量评价为佳(100.00%、100.00%),明显优于对照组(19.05%、85.71%,Z值分别为-11.638、-3.870,P值均小于0.01).结论 早期VSD治疗不能使深Ⅱ度烧伤创面愈合时间提前,但能显著提高其愈合质量,是处理深Ⅱ度烧伤创面的有效方法之一,值得临床关注与进一步研究.

烧伤休克期患者液体复苏中羟乙基淀粉的应用

中分子羟乙基淀粉130/0.4(万汶)为第3代人造胶体,维持胶体渗透压的疗效与血浆相近,在烧伤休克早期救治中得到广泛应用.近年我们在临床实际研究中发现,应用万汶虽然有助于患者平稳度过休克期,但由于万汶不含蛋白成分,不能及时补充烧伤患者休克期蛋白的丢失,可导致患者血清蛋白偏低而不利于后期的治疗.基于此我们进一步开展了不同程度烧伤患者休克前期液体复苏治疗中应用万汶的疗效及血清蛋白变化的研究,以期为万汶临床适应证的选择提供依据.
