Objective To review the researches of donor nerve’s promoting effect on regeneration of reci pient nerve in end-to-side neurorrhaphy at home and abroad. Methods The latest original l iterature concerning donor nerve’s accelerating effect on regeneration of recipient nerve was extensively reviewed. Results Proper nerve cutting may promote nerve regeneration. But how to quantize the cutting volumn was still a challenge. Conclusion It is important to research thedonor nerve in neurorrhaphy, which can provide evidence for cl inical neurorrhaphy so as to achieve good results.
Objective To explore the donor maintenance points of donor donation after brain death (DBD). Methods From December 2011 to January 2012,two cases of organ DBD in our hospital were performed. After diagnosis of brain death,mechanical ventilation,fluid resuscitation,vasoactive drugs,inotropic drugs,and so on were used,and invasive arterial pressure, central venous pressure,heart rate,blood gas exchange,urine output,electrolyte and acid-base balance,body temperature, hematocrit,albumin level were monitored,the donors vital organ perfusion were successfully kept at acceptable level. Results The vital signs of two cases of DBD donors were stable. The livers,kidneys,and corneas were donated,and the functions were stable and normal. Case one was diagnosed for brain death 6h after ICU admitted,the period from diagnosis to organ procurement was 33h. Case two was diagnosed for brain death 8h after ICU admitted,the period from diagnosis to organ procurement was 31h. All transplanted organs,livers,kidneys,and corneas,were working well after operation. Conclusions Donor maintenance process of DBD is the cornerstone to ensuring successfully organ donation and transplantation,which is important to improve the utilization rate of donated organs,and release the severely shortage of organ.
目的总结心脏移植和双肺移植供体心肺同时摘取的经验。 方法解放军第一八一医院心脏中心2012年完成3例同一供体心肺同时摘取,分别完成心脏移植和双肺移植各3例。3例供体为脑死亡,阻断供体升主动脉和主肺动脉后,同时灌注保护液,心脏保护应用组氨酸-色氨酸-酮戊二酸心脏停搏液(HTK液),肺保护应用低钾右旋糖酐液(LPD液);供体心肺热缺血时间为5 min,供心冷缺血时间分别为252 min、323 min和375 min,供体肺冷缺血时间分别为610 min、679 min和738 min;3例心脏移植均采用双腔静脉吻合法,3例肺移植均采用序贯式双肺移植。 结果3例心脏移植均存活;肺移植2例存活,1例死亡。存活患者出院后生活质量良好,随访8~13个月未出现感染、急性排斥反应等并发症。 结论供体心肺同时摘取,同时灌注后分别修剪并再次灌注,分别保存运输,心脏移植和双肺移植可取得满意效果。
Living donor liver transplantation is one of the main solutions to the organ supply-demand discrepancy at present. However, there was a risk of the recipient developing small-for-size syndrome due to insufficient graft volume, while an excessively large graft volume for donation might lead to postoperative liver failure for the donor. In this context, the dual-graft liver transplantation had emerged, which could minimize the volume of liver resection from the each donor to ensure the donor’s safety and provide the adequate volume of liver for the recipient. Yet, this procedure is less commonly performed in our country. In order to promote the steady implementation of dual-graft liver transplantation in China and serve as an important supplement to the donor pool, the West China Hospital of Sichuan University organized relevant experts and draw on the mature experiences of advanced countries in the field of transplantation jointly formulated the “Expert consensus on dual-graft liver transplantation”. The consensus had been developed around aspects such as donor evaluation and selection, surgical methods, and postoperative complications.
【Abstract】ObjectiveTo investigate whether heme oxygenase-1 can alleviate the ischemiareperfusion injury of the aged donor liver. MethodsThe activity of superoxide dismutase (SOD) and catalase (CAT), and the contents of tocopherol (Vit E), ascorbic acid (Vit C) and malondialdehyde (MDA) were measured in the livers of adult SD rats (n=5) and aged SD rats (n=5). The experimental aged donor group (n=30) received intraperitoneal injection of Hemin 24 hours before operation, the control aged donor group(n=30) received saline. The histologic changes and apoptosis in the donor liver were observed. ResultsThe activity of SOD and the contents of Vit E and Vit C decreased significantly in 5 aged rats(P<0.05), but the content of MDA increased(P<0.05). Before the harvesting of the grafts, the activity of SOD and the contents of Vit E and Vit C increased significantly in rats pretreated with Hemin (P<0.05) and the content of MDA decreased(P<0.05). The apoptotic cells in the livers pretreated with Hemin also decreased significantly after reperfusion(P<0.05). ConclusionThe liver of aged rat presents oxidative stress and peroxidative state. Ischemia-reperfusion injury can be alleviated by the induction of HO-1.
目的:探讨64层螺旋CT在活体肝移植供体术前评估中的临床应用价值。方法:活体肝移植术前对拟捐肝者257例行64层螺旋CT检查。扫描序列包括碘浓度监测扫描,自动触发技术进行的肝动脉期、门脉期以及肝静脉期等3期扫描。延迟扫描时间,动脉期22~25s(中位数23s),门脉期42~53s(中位数47s),肝静脉期65~75s(中位数70s)。对比剂注射模式为5mL/s生理盐水20mL+暂停+4~5mL/s对比剂70~120mL+5mL/s生理盐水30mL。图像后处理包括肝脏管道系统重组和肝体积测量。用多平面重组、最大密度投影和容积再现等方法,显示肝动脉、门脉和肝静脉。活体肝体积测量有全肝体积,包括肝中静脉的右半肝体积和不包括肝中静脉的右半肝体积。在同一扫描时相上,测量肝脏和脾脏的CT值,并计算肝脾CT值比值。结果:拟捐肝者257例中,184例行肝移植手术。其中,179例供体接受不包含肝中静脉的右半肝移植。4例双供肝,1例合肝。全部捐肝供体术后恢复良好,无重大并发症和死亡发生。利用64层螺旋CT可对肝脏进行多时相扫描,以及二维、三维图像重组和肝体积测量。结论:64层螺旋CT多时相扫描,二维、三维图像重组和肝体积测量,可为临床活体肝移植术前的供体影像学评估,提供准确、全面的信息。
The quality control of lung transplantation involves many aspects, such as team building, selection of recipients, preoperative diagnosis and evaluation of recipients, maintenance of brain-dead donors, evaluation and acquisition of donors, surgical operation, postoperative management and postoperative follow-up. Precision management is the core concept of operation quality control. Only by normalizing the operation quality control of lung transplantation to provide basic guarantee for multi-team cooperation and development of lung transplantation management in the future, building a complete lung transplantation database to excavate data resources and improve the quality of transplantation, and comprehensively building a Chinese lung transplantation quality control system with multi-team participation and cooperation, can we improve the overall level of surgical diagnosis and treatment of lung transplantation in China.
