Forearm Compartment Syndrome After Intravenous Mannitol Extravasation in a Carbosulfan Poisoning Patient

We report a case of forearm compartment syndrome caused by extravasation of mannitol in an intoxicated patient. The pathophysiology and management of a forearm compartment syndrome from extravasation of mannitol are discussed in this case.     

Effect of aging on salt sensitivity of blood pressure in patients with essential hypertension

Background. Aging is considered to modulate the salt sensitivity of blood pressure (BP), but its mechanisms have not been precisely elucidated. We investigated aging-related changes in salt sensitivity and their mechanisms in patients with essential hypertension. Methods. A high-sodium (Na, 250 mEq/day, for 6 days) diet was given to 32 essential hypertensive patients of different ages (younger, aged <30 years, n = 8; middle-aged, 30–50 years, n = 10; older, ≥50 years, n = 14) after they had had a low-Na diet (25 mEq Na/day) for 3 days. Cardiac output was measured by dye-dilution, and forearm blood flow (FBF) and venous volume (VV40) by strain-gauge plethysmography. Results. The Na-induced rise in mean BP increased with age (3.2 ± 2.0%; 6.9 ± 2.1%; and 11.7 ± 1.4% respectively, in the younger, middle-aged, and older groups, and this was accompanied by a salt-induced rise in cardiac index and FBF. VV40 decreased with the high-Na diet in older hypertensives (−15.7 ± 6.1%) and the change was significantly less (P < 0.05) than in the younger group (9.3 ± 9.0%). Conclusion. The enhanced salt sensitivity of BP that occurs with aging in patients with essential hypertension is due to increased cardiac output, probably through a venous constriction-related elevation of venous return.

骨间前血管前臂背侧皮神经营养血管皮瓣的临床应用

目的：报道改进前臂背侧皮神经营养血管逆行皮瓣的手术方法及临床效果。方法：对腕背以远的皮肤缺损创面，设计以骨间前血管腕背支为血管蒂，沿前臂背侧皮神经营养血管轴切取皮瓣逆向转位修复。结果：临床应用8例，皮瓣全部皮活。随访6－12个月，皮瓣质地优良，外形与功能恢复满意。结论：该皮瓣切取方便，血供可靠，不累及前臂主要血管，适于修复虎口、腕背及手背等处较大面积的皮肤软组织缺损。     

Acumed前臂髓内钉治疗成人前臂双骨折

目的 :探讨Acumed前臂髓内钉治疗成人前臂双骨折的临床疗效。方法:2009年1月至2016年12月采用Acumed髓内钉治疗成人前臂双骨折患者86例,男54例(62.8%),女32例(37.2%),年龄18~72岁,平均36.8岁;右侧50例,左侧36例。记录病例手术时间、术中出血量、放射暴露时间、骨折愈合时间、并发症,DASH问卷调查(Disabilities of the Arm,Shoulder and Hand questionnaire)和Grace-Eversman疗效评级以评估髓内钉治疗前臂骨折的临床效果。结果:86例患者均获随访,随访时间48~144周,平均86.8周;术中出血量30~80 ml,平均52 ml;放射性暴露时间1~6 min,平均2.5 min;手术时间31~55 min,平均46 min。85例骨折顺利愈合,愈合时间10~16周,平均13.3周。3例患者出现并发症,其中1例肥大性骨不连,1例尺桡骨间骨桥形成,1例拇长伸肌腱损伤。DASH评分0~28分,平均15.6分;Grace-Eversman评价结果,优65例,良15例,可5例,差1例。结论:前臂髓内钉用于治疗成人前臂双骨折具有微创、手术时间短、并发症少等优点,临床效果满意。     

Does infrared visualization improve selection of venipuncture sites for indwelling needle at the forearm in second-year nursing students?

ObjectivesTo evaluate the effectiveness of a vein visualization display system using near-infrared light (“Vein Display”) for the safe and proper selection of venipuncture sites for indwelling needle placement in the forearm.MethodsTen second year nursing students were recruited to apply an indwelling needle line with and without Vein Display. Another ten participants were recruited from various faculty to serve as patients. The quality of the venipuncture procedure at various selected sites was evaluated according to a scale developed by the authors. Time, scores and patterns of puncture-site selection were compared with respect to three different methods: [1] attempt 1 (tourniquet only), [2] attempt 2 (Vein Display only) and [3] attempt 3 (both). To validate the effectiveness of Vein Display, 52 trials were conducted in total.ResultsWe found that venipuncture site selection time was significantly improved with the Vein Display, particularly in the case of difficult to administer venipuncture sites. Overall, we found no significant difference with respect to venipuncture quality, as determined by our scale.ConclusionThese results suggest that equipment such as the Vein Display can contribute immensely to the improvement of practical skills, such as venipuncture, especially in the context of elderly patients.     

The management of congenital and acquired problems of the distal radioulnar joint in children

Pain in the ulnar aspect of the pediatric wrist is an uncommon problem; however, when pain does occur it is usually the result of antecedent bony trauma or an underlying skeletal abnormality, which may lead to ulnar-sided wrist pain of varying etiology. The clinician must to be able to identify these entities within the pediatric wrist in order to make the appropriate diagnosis and plan for surgical intervention to prevent ongoing damage to the distal radioulnar joint (DRUJ). This article reviews the etiology, clinical presentation, and treatment strategies for the management of the unique problems that can affect the pediatric and adolescent DRUJ.
