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.

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.

Randomized Controlled Trial Comparative StudyRandomized, comparative study of the effectiveness of three different techniques of interscalene brachial plexus block using 0.5% ropivacaine for shoulder arthroscopy.
Interscalene brachial plexus block is an effective regional anesthesia technique for shoulder surgeries. The superiority of the popular ultrasound-guided blocks over peripheral nerve stimulator-confirmed blocks remains unclear. In this study the efficacy of these different block techniques was compared. ⋯ Peripheral nerve stimulator-confirmed needle placement is not necessary to ensure effectiveness of ultrasound-guided blocks, which is expressed as a lack of necessity of conversion to general anesthesia. Nevertheless, the dual guidance technique is recommended to reduce the risk of complications and might be considered the regional anesthesia of choice for shoulder surgery.

Clinical TrialIs the change of percutaneous oxygen pressure available to judge the effects of brachial plexus block?
To know the objective methods of the effects of the brachial plexus block, we studied the changes in percutaneous oxygen pressure (tcPO₂) with the hypothesis that tcPO₂ increases significantly on the blocked arm in comparison with the non-blocked arm, a phenomenon which is connected with vasodilation following the brachial plexus block. ⋯ Changes of tcPO₂ are not useful in order to assess the effects of the interscalene block under oxygen administration.
