Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
目的探讨毒品注射致假性动脉瘤急性破裂大出血后的急救处理。方法回顾性分析12例毒品注射致假性动脉瘤急性破裂出血患者的临床资料。结果均行单纯清创和血管修补术，术后1例患者诉右足轻度麻木，出院2个月后消失，无跛行。其余11例患者术后至出院无明显缺血表现。结论对毒品注射所致假性动脉瘤急性破裂大出血患者行单纯清创和血管修补术，手术操作简便，术后患肢血供恢复好，且费用低，适合在广大基层医院开展。
ObjectiveTo summarize the research progress of CT related to esophageal varices of cirrhotic patients complicated with portal hypertension.MethodsRelevant CT literatures of esophageal varices of cirrhotic patients complicated with portal hypertension were collected to make an review,then summarized the research status and progress of CT in the diagnosis and evaluation of lower esophageal varices.ResultCT had a good correlation with endoscopic diagnosis of esophageal varices, and CT was of great value in evaluating the presence, degree, and risk of esophageal varicose veins, especially in predicting the risk of esophageal varicose veins, which could be used as an effective modality to assist endoscopic examination to a certain extent.ConclusionsCT is an important examination method for esophageal varices, which has important value in diagnosis and evaluation. In the future, more further researches can be carried out to provide more strong and accurate support for the diagnosis and treatment of esophageal varices.
The real-time monitoring of cerebral hemorrhage can reduce its disability and fatality rates greatly. On the basis of magnetic induction phase shift, we in this study used filter and amplifier hardware module, NI-PXI data-acquisition system and LabVIEW software to set up an experiment system. We used Band-pass sample method and correlation phase demodulation algorithm in the system. In order to test and evaluate the performance of the system, we carried out saline simulation experiments of brain hemorrhage. We also carried out rabbit cerebral hemorrhage experiments. The results of both saline simulation and animal experiments suggested that our monitoring system had a high phase detection precision, and it needed only about 0.030 4s to finish a single phase shift measurement, and the change of phase shift was directly proportional to the volume of saline or blood. The experimental results were consistent with theory. As a result, this system has the ability of real-time monitoring the progression of cerebral hemorrhage precisely, with many distinguished features, such as low cost, high phase detection precision, high sensitivity of response so that it has showed a good application prospect.
ObjectiveTo analyze the clinical characteristics of cerebral shock after intracerebral emorrhage (ICH) to enhance the understanding of cerebral shock after ICH. MethodsA total of 136 patients with ICH admitted to hospital from February 2010 to December 2011 were enrolled in this study.Barthel index (BI) and NIH Stroke Scale (NIHSS) were finished within 48 hours.All the patients were divided into cerebral shock group and no cerebral shock group.All of the 136 patients were matched to shock group (39 cases) and no shock group (39 cases) by the baseline NIHSS score.After 6 months,we judged the prognosis of stroke patient by mRS and compared the prognosis between the two groups. ResultsIn 136 patients,95 had cerebral shock (69.85%),and 41 didn't.The NIHSS score in the shock group was higher than that in the no shock group,but the BI score was lower in the shock group.Six months later,2 patients died in shock group,in which lost follow up was in 1,good prognosis in 11,and poor prognosis in 25.In no shock group,1 patient died,2 were lost of follow up,and the prognosis was good in 29 and poor in 7.The prognosis in the shock group was poorer than that in the no shock group. ConclusionThere are neurological deficit symptoms and poor self-care ability in ICH patients associated with brain shock.The period of brain shock impact the prognosis of the patients with cerebral hemorrhage;early functional rehabilitation for stroke patients with brain shock is expected to improve the prognosis of patients with cerebral stroke.
目的:探讨心脏机械瓣膜置换术后抗凝治疗中,消化道出血发生的危险因素及防治措施。方法:回顾性研究2001年3月至2008年7月我院16例机械瓣膜置换术后抗凝治疗中消化道出血患者的临床资料,分析发生的危险因素,并总结其诊治经验。结果:心脏机械瓣膜置换术后患者抗凝治疗中消化道出血发生在服用华法令后3天～5年,平均147.53±136.71天。其中,上消化道出血12例,下消化道出血4例;保守治疗11例,内窥镜治疗4例;死亡2例(DIC及多器官功能衰竭各1例),病死率12.5%(2/16)。出血组患者术中转流时间(142.73 min±49.81 min)明显长于对照组(98.27 min±39.52 min)(Plt;0.05),华法令平均用药量(2.46±0.53 mg/d)与对照组(2.38±0.69 mg/d)无明显差异(Pgt;0.05),国际标准比值(INR)均值(2.79±0.57))明显大于对照组(1.49±0.58)(P lt;0.05)。消化道出血治疗期间停用华法令5～19天,平均13±2天,所有痊愈患者消化道出血治疗期间及出院后随访3月内均无栓塞及消化道再出血事件发生。结论;⑴心脏机械瓣膜置换术后早期(3月内)抗凝治疗发生消化道出血的危险因素包括术中转流时间过长和抗凝强度过大(INR＞2.0),晚期则可能与合并使用非甾体类抗炎药有关;⑵ 消化道出血治疗期间,华法林停用2周较为安全。
