ReviewMethods of pain assessment in adult intensive care unit patients - Polish version of the CPOT (Critical Care Pain Observation Tool) and BPS (Behavioral Pain Scale).
Many patients treated in the intensive care unit (ICU) experience pain that is a source of suffering and leaves a longterm imprint (chronic pain, post-traumatic stress disorder). Nearly 30% of patients experience pain at rest, while the percentage increases to 50% during nursing procedures. Pain in ICU patients can be divided into four categories: continuous ICU treatment-related pain/discomfort, acute illness-related pain, intermittent procedural pain and pre-existing chronic pain present before ICU admission. ⋯ Although international guidelines recommend the use of validated tools for pain evaluation, they underline the need for translation into a given language. The authors of this publication obtained an official agreement from the authors of the two behavioral scales - CPOT and BPS - for translation into Polish. Validation of these tools in the Polish population will aid their wider use in pain assessment in ICUs in Poland.

Guidelines for infusion fluid therapy rarely take into account that adverse effects occur in a dose-dependent fashion. Adverse effects of crystalloid fluids are related to their preferential distribution to the interstitium of the subcutis, the gut, and the lungs. The gastrointestinal recovery time is prolonged by 2 days when more than 2 litres is administered. ⋯ Coagulopathy is aggravated by co-existing hypothermia. Although oedema can occur from both crystalloid and colloid fluids, these differ in pathophysiology. To balance fluid-induced adverse effects, this review suggests that a colloid fluid is indicated when the infused crystalloid volume exceeds 3-4 litres, plasma volume support is still needed, and the transfusion of blood products is not yet indicated.

ReviewNoninvasive ventilation in difficult endotracheal intubation: systematic and review analysis.
Noninvasive ventilation has been widely used in the management of acute respiratory failure in appropriate clinical settings. In addition to known benefit of alleviating the need for invasive mechanical ventilation, recent literature suggested its beneficial use in the process of endotracheal intubation. ⋯ Large randomized controlled studies focused on alternative approaches to endotracheal intubation in severe hypoxemic respiratory failure are largely missing but there are several retrospective cohort analysis and reports describing the novel technique describing the application of noninvasive ventilation during endotracheal intubation. Noninvasive ventilation can be used as an adjunct intervention that may maintain oxygenation and ventilation, prevent significant hemodynamic instability and provide a pneumatic stent to maintain upper airway patency, thus reducing the risks of intubation-related complications.

Review Comparative StudyA comparison of non-endoscopic and endoscopic adhesiolysis of epidural fibrosis.
Low back and leg pain may be due to many causes, one of which is scarring in the epidural space. Epidural scarring may provoke this pain for many reasons: nerves may be trapped by scars, while veins in the epidural space press down upon the nerves and become enlarged, putting pressure on the nerves. ⋯ A search of the MEDLINE and Embase databases was conducted for the period between 1970 and 2014 using the search terms "adhesiolysis", "lysis of adhesions", "epiduroscopy", "epidural neuroplasty", "epidural adhesions", "radiofrequency lysis adhesion" and "epidural scar tissue" in order to identify articles relevant for this review. The purpose of this review is to describe the effectiveness and complications present in a comparison of non-endoscopic, endoscopic and pulsed radiofrequency endoscopic procedures in lysis of adhesions in epidural fibrosis.

ReviewEarly severe acute respiratory distress syndrome: What's going on? Part I: pathophysiology.
Severe acute respiratory distress syndrome (ARDS, PaO₂/FiO₂ < 100 on PEEP ≥ 5 cm H₂O) is treated using controlled mechanical ventilation (CMV), recently combined with muscle relaxation for 48 h and prone positioning. While the amplitude of tidal volume appears set < 6 mL kg⁻¹, the level of positive end-expiratory pressure (PEEP) remains controversial. This overview summarizes several salient points, namely: a) ARDS is an oxygenation defect: consolidation/ difuse alveolar damage is reversed by PEEP and/or prone positioning, at least during the early phase of ARDS b) ARDS is a dynamic disease and partially iatrogenic. ⋯ Therefore, in early severe diffuse ARDS, this review argues for a combination of a high PEEP (preferably titrated on transpulmonary pressure) with spontaneous ventilation + pressure support (or newer modes of ventilation). However, conditionalities are stringent: upfront circulatory optimization, upright positioning, lowered VO₂, lowered acidotic and hypercapnic drives, sedation without ventilatory depression and without lowered muscular tone. As these propositions require evidence-based demonstration, the accepted practice remains, in 2016, controlled mechanical ventilation, muscle relaxation, and prone position.
