面部烧伤病人感染危险因素的分析及护理

面部是人体的暴露部位,在烧伤病中占有较大比例。烧伤后很容易引起组织毁损及吸入性损伤,反复感染影响创面愈合,伤愈后常留有色素沉着、瘢痕增生、睑外翻、唇外翻等后遗症,影响面部美观及五官功能,给病人带来长期精神痛苦。我院1998年—2001年面部烧伤病人感染率为6.09%。因此,2002年—2005年,我科护理人员加强面部烧伤感染的防护措施,使其感染率下降到2.49%。正确的护理干预可以有效预防病人感染,减轻各种并发症的发生。现对面部烧伤病人的护理干预报告如下。1临床资料我科2002年—2005年共收治烧伤病人558例,其中面部烧伤281例,男195例,女…

36例胰腺浆液性囊腺瘤的临床分析

目的：探讨胰腺浆液性囊腺瘤的诊断和治疗。方法：对1998年6月至2006年9月瑞金医院收治的36例病理诊断为胰腺浆液性囊腺瘤的临床资料进行回顾性分析。结果：胰腺浆液性囊腺瘤好发于中老年女性,多见于胰腺头颈部,无特征性临床表现。B超和CT诊断囊性肿瘤的正确率分别为69%（25/36）和94%（34/36）。CT对于囊腺瘤的诊断正确率为80%（29/36）,对浆液性囊腺瘤的诊断正确率为61%（22/36）。在不能排除或考虑实性假乳头状瘤的病人中MRI对于囊腺瘤的诊断正确率80%（4/5）。本组35例行手术治疗,其中7例行胰十二指肠切除;11例行胰腺节段切除;12例行胰体尾切除;5例行局部切除,1例行剖腹探查活组织检查。10例术后出现并发症,包括胰瘘、内出血、幽门梗阻、胰腺假性囊肿合并肠瘘病人及不同程度的胸腔积液。1例因内出血死亡。本组3例失访,32例获随访,除2例因其它疾病死亡,其余均健在,术后无复发。结论：CT和MRI,结合肿瘤学指标和临床病理特征可大大提高浆液性囊腺瘤的术前诊断率。浆液性囊腺瘤是一种良性的肿瘤,但手术治疗并发症较多。大多数浆液性囊腺瘤可考虑随访;有症状的胰腺浆液性囊腺瘤,或与黏液性囊性肿瘤不能鉴别者,应手术治疗。     

Feasibility of treating hyperfibrinogenemia with intermittently administered batroxobin in patients with ischemic stroke/transient ischemic attack for secondary prevention.

This study evaluated the safety and efficacy of batroxobin in treating hyperfibrinogenemia for secondary stroke prevention. Patients with ischemic stroke or transient ischemic attack (TIA) were measured for plasma fibrinogen levels. Selected participants had concomitant hyperfibrinogenemia (plasma fibrinogen > or = 3.0 g/l). Patients enrolled between 1 July 2003 and 31 December 2004 were treated with batroxobin; patients enrolled between 1 January 2002 and 30 June 2003 were treated without batroxobin. Batroxobin was administered intermittently via intravenous injection at 3-monthly intervals. Patients in both groups were followed for 1 year. Any cerebrovascular events and suspected adverse events were recorded. In total, 112 ischemic stroke/TIA patients with concomitant hyperfibrinogenemia were enrolled, 52 being treated with batroxobin and 60 without batroxobin. Six patients (11.5%) with batroxobin and 16 patients (26.7%) without batroxobin had recurrent cerebral ischemic events during follow-up. Stroke/TIA recurrence in patients without batroxobin was higher than that in patients with batroxobin (P < 0.05). Two patients with batroxobin and two patients without batroxobin developed hemorrhagic stroke during follow-up. There were five deaths (9.6%) in the batroxobin group, and seven deaths (11.7%) in the nonbatroxobin group during follow-up (P > 0.05). Intermittent intravenous injection of batroxobin can efficiently reduce the risk for stroke/TIA recurrence in patients with concomitant hyperfibrinogenemia.

Isoflurane Preconditioning Improves Long-term Neurologic Outcome after Hypoxic-Ischemic Brain Injury in Neonatal Rats

Background: Preconditioning the brain with relatively safe drugs seems to be a viable option to reduce ischemic brain injury. The authors and others have shown that the volatile anesthetic isoflurane can precondition the brain against ischemia. Here, the authors determine whether isoflurane preconditioning improves long-term neurologic outcome after brain ischemia.

Methods: Six-day-old rats were exposed to 1.5% isoflurane for 30 min at 24 h before the brain hypoxia-ischemia that was induced by left common carotid arterial ligation and then exposure to 8% oxygen for 2 h. The neuropathology, motor coordination, and learning and memory functions were assayed 1 month after the brain ischemia. Western analysis was performed to quantify the expression of the heat shock protein 70, Bcl-2, and survivin 24 h after isoflurane exposure.

Results: The mortality was 45% after brain hypoxia-ischemia. Isoflurane preconditioning did not affect this mortality. However, isoflurane preconditioning attenuated ischemia-induced loss of neurons and brain tissues, such as cerebral cortex and hippocampus in the survivors. Isoflurane also improved the motor coordination of rats at 1 month after ischemia. The learning and memory functions as measured by performance of Y-maze and social recognition tasks in the survivors were not affected by the brain hypoxia-ischemia or isoflurane preconditioning. The expression of Bcl-2, a well-known antiapoptotic protein, in the hippocampus is increased after isoflurane exposure. This increase was reduced by the inhibitors of inducible nitric oxide synthase. Inducible nitric oxide synthase inhibition also abolished isoflurane preconditioning-induced neuroprotection.

The Application of Topical Anesthesia Combined with Subconjunctival Anesthesia for Glaucoma Surgery

Purpose: To evaluate the feasibility, reliability and analgesia effect of topical anesthesia combined with subconjunctival anesthesia in anti-glaucomatous surgery.Methods: Two hundred and four cases (357 eyes) underwent anti-glaucomatous surgeries under topical anesthesia with 0.5％ Alcaine eye drops combined with subconjunctival anesthesia with 2％ Lidocaine. The analgesic effect was analysed with visual analogue pain scale.Results: Among all of 357 eyes, 62 eyes underwent peripheral iridectomy, 67 eyes underwent simple trabeculectomy, 167 eyes underwent compound brabeculectomy and 12 eyes nonpenetrating trabecular surgery. The effects of anesthesia were as follows: 304 eyes (85.2％) were painless (Grade Ⅰ), 50 eyes (14.0％) were slight painful (Grade Ⅱ), and 3 eyes (0.8％) were more painful (Grade Ⅲ) during surgery. And no severe complications were observed in all the cases during surgery and postoperatively. Amaurosis fugax was not observed in the glaucoma patients at the late stage with narrow vi
