Evaluation of the short-term results of closed reduction and percutaneous K-wires fixation of displaced intra-articular calcaneal fractures (DIACF)

PurposeOptimum management of displaced intra-articular calcaneal fractures (DIACF) still controversial. Open surgery carries the risk of wound complications, while non-operative management has a high incidence of arthrosis. To avoid these complications, minimally invasive and percutaneous fixation was introduced. The purpose of this study was to prospectively evaluate the short term clinical and radiological outcomes after closed reduction and percutaneous fixation of DIACF using K-wires.Patients and methodsOutcomes of twenty patients were evaluated at the final follow up. A functional assessment using the AOFAS scoring system. Radiological parameters recorded included three angles (Böhler’s, Gissane and posterior facet inclination angles) and three distances (calcaneal length, height and width). Any complications were reported at any follow-up.ResultsThe mean patient’s age was 33 ± 15.2 years, 8 (40%) patients with type II fractures, 10 (50%) patients with type III fractures, and 2 (10%) with type IV fracture according to Sanders classification. After a mean follow-up of 9 months, the mean AOFAS score was 84, excellent in 9 patients (45%), good in 9 (45%), and fair in 2 (10%). At the final follow-up the Böhler’s angle, Gissane angle and PFIA was 25.1° ± (5.2), 119.9° ± (9.4) and 51.7° ± (5.9) respectively and the calcaneal height, length and width was 41.8 mm ± (2.1), 75.1 mm ± (3.01) and 40.9 mm ± (2.6) respectively. We had no cases of deep infection, 20% had significant subtalar arthritis.ConclusionThe closed reduction and percutaneous fixation technique for DIACF management offered acceptable clinical and radiographic outcomes, with fewer complications when compared to other management options.     

Tracheal intubation

Tracheal intubation is the act of placing a tube into the trachea. The tube enables oxygen delivery and removal of carbon dioxide, while also allowing for the administration of pharmacological agents. Intubation is the most reliable method of maintaining an airway under anaesthesia, and for protection against aspiration of stomach contents. Traditionally, intubation is achieved by direct visualization of the glottis, but now indirect laryngoscopy (via a videolaryngoscope) is a common alternative. Prior to embarking upon intubation, a thorough patient history and examination must be undertaken by the laryngoscopist; equipment must be prepared and checked; a trained assistant present; and an experienced anaesthetist available in case assistance is required. Once the endotracheal tube has been placed, correct positioning must be confirmed via both clinical examination and monitoring, including capnography. Tracheal intubation is a procedure that should only be undertaken by trained operators and is not without risk. It is important to note that it is failure to oxygenate patients rather than failure to intubate that ultimately leads to serious morbidity and mortality. The Difficult Airway Society has produced guidelines on how to manage unanticipated difficulty in tracheal intubation; it is essential that every practitioner trained to intubate patients is familiar with these algorithms and the key principles of safe airway management.     

A comparison of head injuries in male and female lacrosse participants seen in US emergency departments from 2005 to 2016

Introduction

In the United States there has been a large increase in participation in lacrosse for both males and females. The purpose of this study was to analyze the number of head injuries, injury rates (calculated using the reported number of participants) and types of head injuries that are seen in emergency departments in the United States.

应用无死腔气管插管提高正常和急性肺损伤兔的机械通气效率

目的：观察无死腔气管插管能否提高急性呼吸衰竭常规机械通气的效果。方法：应用一种新型无死腔气管插管和普通聚氯乙烯气管插管对正常和急性肺损伤兔进行常规通气，对两种气管插管的肺气体交换和气道内气体动力学及血流动力学变化进行比较。无死腔气管插管用２根Ｐｏｔｅｘ气管插管远端３ｃｍ处纵切后对粘而成。５只新西兰成年兔，麻醉下气管切开，在持续应用潘龙阻断自主呼吸条件下，随机用新型气管插管和普通气管插管Ｓｅｒｖｏ９００Ｃ进行机械通气，每次持续３０分钟，测定并记录动脉血压、气道压力、血流动力学参数和呼气末ＣＯ２浓度。结果：在正常肺和急性肺损伤条件下，新型气管插管可使所有动物的ＰａＣＯ２和生理死腔／潮气量（ＶＤ／ＶＴ）下降，ＰａＣＯ２分别下降１．４０±０．２０ｋＰａ（１ｋＰａ＝７．５ｍｍＨｇ）和１．６０±０．３０ｋＰａ（Ｐ＜０．０１），ＶＤ／ＶＴ分别下降０．１３±０．０２和０．１５±０．０４（Ｐ＜０．０１）；ＰａＯ２、气道压力和血流动力学无显著变化。结论：无死腔气管插管可明显提高常规机械通气效率。

A Paradigm for Design of Closed Loop Neuromuscular Electrical Stimulator Control Systems

Abstract: The use of neuromuscular electrical stimulation (NMES) for rehabilitation of gait in spinal patients is widely known. The best results can be obtained with the use of biomechanical sensors and a closed loop NMES system. One of the biggest problems faced in the design of control systems for closed-loop operation, in gait rehabilitation, is the variation of the mechanical conditions during the phases of gait. This work presents a new approach to ease the design of rule-based closed loop systems for operation in conditions such as gait rehabilitation.
