Purpose:Trauma centres have been proven to provide better outcomes in developed countries for overall trauma,but there is limited literature on the systematic factors that describe any discrepancies in outcomes for trauma laparotomies in these *** study was conducted to examine and interrogate the effect of systematic factors on patients undergoing a trauma laparotomy in a developed country,intending to identify potential discrepancies in the ***:This was a retrospective study of all laparotomies performed for trauma at a level 1 trauma centre in New *** adult patients who had undergone an index laparotomy for trauma between February 2012 and November 2020 were identified and laparotomies for both blunt and penetrating trauma were *** laparotomies and trauma laparotomies in children were *** primary clinical outcomes reviewed included morbidity,length of hospital stay,and *** statistical analysis was performed using R ***:During the 9-year study period,204 trauma laparotomies were performed at Waikato *** majority(83.3%)were performed during office hours(170/204),and the remaining 16.7%were performed after hours(34/204).And 61.3%were performed on a weekday(125/204),whilst 38.7%were performed on the weekend/public holiday(79/204).Most of the parameters in office hours and after hours groups had no statistically significant difference,except lactate(p=0.026).Most of the variables in weekday and weekend groups had no statistically significant difference,except pH,lactate,length of stay,and gastrointestinal complications(p=0.012,p<0.001,p=0.003,p=0.020,respectively).Conclusion:The current trauma system at Waikato hospital is capable of delivering care for trauma laparotomy patients with the same outcome regardless of working hours or after hours,weekday or *** confirms the importance of a robust trauma system capable of responding to the sudden demands placed on it.

为提高纳米纤维神经移植物的接触引导,设计了一种含有取向纳米纤维束的"芯鞘"型神经移植物,它利用静电纺高取向纳米纤维膜,两次卷绕形成"芯"和"鞘",最后通过静电纺丝喷覆而成。利用扫描电镜观察并表征了纤维及其移植物形态,测试了力学性能,将此移植物用于大鼠10mm坐骨神经缺损,术后两月通过体外刺激和组织学观察了修复效果。结果表明:通过调整静电纺收集转辊转速可获得高取向聚乳酸纳米纤维,纳米纤维膜工程应力和伸长率达到(49.32±14.83)MPa和17.71%±0.06%,利用该膜构建的神经移植物缝合强力达到(1.18±0.40)N/针,能支持与保护神经再生,移植两月后,大鼠能够感知热与外力刺激,组织学观察发现,有神经纤维和血旺细胞长入神经移植物,证明了该构建技术的可行性,并有可能为神经修复提供一种新的移植材料。
