This review introduces state-of-the-art Web-based education and shows how the e-learning model can be applied to an anaesthesia department using Open Source solutions, as well as lifelong learning programs, which is happening in several European research projects. ⋯ The first step when adapting a course to e-learning is to re-define the educational/learning model adopted: cooperative learning and tutoring are the two key concepts. This means that traditional lecture notes, books and exercises are no longer effective; teaching files must use rich multimedia content and have to be developed using the new media. This can lead to several pitfalls that can be avoided with an accurate design phase.

Echocardiography has been used perioperatively as an important diagnostic tool since the 1980s. Introduction of this new technique has been beneficial to our practice, but has also introduced questions and issues related to methods of teaching, requirements for demonstration of competence and testing and certification processes as evidence of satisfactory completion of necessary learning parameters. This article will review the issues presented to date, how they have been addressed, and what options could be arriving in the future. ⋯ Perioperative echocardiography has rapidly become an integral part of anesthetic practice. The training and certification process has been formalized. There are still issues related to difficulty of training individuals outside core residency programs.

ReviewUltrasound guidance in peripheral regional anesthesia: philosophy, evidence-based medicine, and techniques.
This article introduces the use of ultrasound to facilitate peripheral regional anesthesia. ⋯ Ultrasound technology represents an ideal mechanism by which the regional anesthesiologist can attain the safety, speed, and efficacy of general anesthesia. Ultimately, it is the correct peri-neural spread of local anesthetic around a nerve that provides safe, effective, and efficient anesthetic conditions.

ReviewWhich muscle relaxants should be used in day surgery and when.
After myorelaxants, myalgia and residual curarization may complicate recovery. Local anaesthesia and minimally invasive airway management make myorelaxants disputable in many outpatient procedures; nevertheless, neuromuscular blockade may be necessary to facilitate intubation or maintain muscle relaxation. Agent selection criteria are discussed. ⋯ Ear-nose-throat, open eye surgery and laparoscopy may demand myoresolution. Regional and minimally invasive anaesthesia are alternative solutions. Central and peripheral nerve blocks are associated with increased induction time, reduced pain scores, and decreased need for analgesics. Central neuraxial block, however, is associated with prolonged outpatient unit stay. Bad intubating conditions may cause pharyngo-laryngeal complications: the decision to avoid myorelaxants for tracheal intubation appears illogical. Incidence of postoperative residual curarization remains very high. Sugammadex offers new perspectives.

ReviewAlveolar recruitment versus hyperinflation: A balancing act.
To address lung recruitment according to pressure/volume curves, along with regional recruitment versus hyperinflation evidence from computed tomography and electrical impedance tomography. ⋯ Positive end-expiratory pressure levels must be high enough to minimize recruitment/derecruitment cycling. Balancing recruitment versus overdistension may require thoracic tomography, to assure sufficient improvement in oxygenation while limiting hypercarbia.
