Ultrasound has been revolutionising our specialty. The introduction of new, portable machines and goal-directed protocols has led many anaesthetists to use this diagnostic tool in their daily practice. ⋯ In order to perform a credible ultrasound examination, a proper level of competence is required. In this review article, the authors present various critical ultrasound applications.

Randomized Controlled Trial Comparative StudyNew generation pulse oximetry in the assessment of peripheral perfusion during general anaesthesia - a comparison between propofol and desflurane.
A pulse oximeter is a standard device for perioperative monitoring. It is well known that the early detection of tissue hypoxia is of great importance. It has been made easier due to a new generation pulse oximetry device from Masimo. This enables measurements of the peripheral perfusion index (PI) in real time. It has been found that volatile anaesthetics such as sevoflurane and desflurane increase the perfusion index. As we know, no data is available about perfusion index during propofol/remifentanil total intravenous anaesthesia. ⋯ Both intravenous propofol/remifentanil and desflurane/fentanyl general anaesthesia increase peripheral perfusion. An increase in end-tidal desflurane concentration raises peripheral perfusion.

Mechanical ventilation of disease-affected lungs, as well as being an inadequate mode of ventilation for initially healthy lungs, can cause significant changes in their structure and function. In order to differentiate these processes, two terms are used: ventilator-associated lung injury (VALI) and ventilator-induced lung injury (VILI). In both cases, lung injury primarily results from differences in transpulmonary pressure - a consequence of an imbalance between lung stress and strain. ⋯ None of the assessed methods of reducing VALI and VILI has been found to be entirely satisfactory, yet studies evaluating oscillatory ventilation, liquid ventilation, early ECMO, super-protective ventilation or noisy ventilation and administration of certain drugs are under way. Low tidal volume ventilation and adequately adjusted PEEP appear to be the best preventive measures of mechanical ventilation in any setting, including the operating theatre. Furthermore, this paper highlights the advances in VILI/VALI prevention resulting from better understanding of pathophysiological phenomena.

Labour analgesia in most developed countries is funded by the state, available to every woman in labour, and plays an important role in the everyday activities of most anaesthetists. This paper presents the second part of an Obstetric Anaesthesia Survey which was conducted in 2009. The first part of the Survey, relating to anaesthesia for caesarean sections, was published in 2010. ⋯ Epidural labour analgesia was offered for 24 hours per day and free of charge in only 20% of hospitals. Without public pressure it will be difficult to get more funding from the National Health Fund (NFZ) to enable other hospitals, especially those with small obstetric units, to introduce regional labour analgesia. Although the 2009 guidelines addressed most of the issues regarding the conduct of epidural labour analgesia, changes need to be made in Polish law to allow midwives to be appropriately trained to look after parturients with regional labour analgesia.

Anaesthetic management for endovascular treatment of unruptured intracranial aneurysms.
Endovascular techniques for treatment of intracranial aneurysms are increasingly commonly applied. In general, the procedures are short, require general anaesthesia and complete immobilisation of patients. The aim of the present study was to assess the usefulness of general anaesthesia with propofol and laryngeal mask airway for endovascular management of intracranial aneurysms based on analysis of haemodynamic stability. ⋯ General anaesthesia with propofol and LMA ensures suitable conditions for endovascular treatment of intracranial aneurysms.
