Randomized Controlled Trial Comparative Study
Less perilaryngeal gas leakage with SLIPA™ than with LMA-ProSeal™ in paralyzed patients.
The aim of this study was to compare the Streamlined Liner of the Pharynx Airway (SLIPA™) with the ProSeal Laryngeal Mask Airway (LMA-ProSeal™) in mechanically ventilated paralyzed patients undergoing laparoscopic gynecologic surgery. ⋯ Both the SLIPA and the LMA-ProSeal can be used effectively and without severe complications in paralyzed patients undergoing laparoscopic gynecological surgery. However, the SLIPA offers the advantage of less perilaryngeal gas leakage than the LMA-ProSeal with change in head position and during insufflation of the peritoneal cavity. This trial is registered with ANZCTR (ACTRN12609000914268).

Review Meta Analysis
Perioperative intravenous lidocaine infusion for postoperative pain control: a meta-analysis of randomized controlled trials.
Various strategies have been proposed for postoperative pain control. Among those, intravenous lidocaine infusion (IVLI) has gained in interest. However, its clinical benefit remains unclear. This systematic review is an evaluation of the analgesic efficacy and safety of IVLI during general anesthesia. ⋯ Perioperative IVLI reduced postoperative pain and opioid requirement, as well as ileus recovery time, hospital length of stay, and nausea/vomiting. Intravenous lidocaine infusion was effective mainly in abdominal surgery populations. Considering that toxic levels were detected and that adverse events were not systematically screened for in most studies, dose and safety of IVLI should be established before recommending its use.

Case Reports
Complications of peripheral nerve catheter removal at home: case series of five ambulatory interscalene blocks.
The placement of continuous peripheral nerve catheters on an ambulatory basis is increasing and is routine at our institution. There are few reports of complications associated with peripheral nerve catheter removal in the literature. Described herein is a case series of five patients where complications related to catheter withdrawal were observed. ⋯ There can be various causes for difficulty with catheter removal, such as a technical aspect of catheter placement, catheter design, tissue reaction at the catheter site, or a combination thereof. The majority of complications related to outpatient perineural catheters can be handled over the telephone, but our case series may highlight a potential management dilemma in placing continuous stimulating perineural catheters on an ambulatory basis.

Despite significant contributions to medicine, anesthesiology is poorly recognized and faces the threat of "deprofessionalization". Clear articulation of its work and professional values plays an integral role in maintaining the viability of a profession. The purpose of this qualitative study is to explore anesthesiologists' perspectives in order to define the distinct elements of their work and their professional values. ⋯ Anesthesiology is characterized by its distinct work and core professional values. Under the threat of deprofessionalization, the practice of anesthesiology should be guided by its professional values in defining and envisioning its future.

Transesophageal echocardiography (TEE) is becoming a standard imaging tool during cardiac surgery as well as an important diagnostic tool in cardiology and in intensive care, resulting in an increasing demand for TEE training. To address the problem of limited time for learning during TEE studies, we have developed a novel online application that allows users to visualize each of the 20 standard diagnostic TEE views in conjunction with a three-dimensional (3D) heart model that can be rotated and "cut away" above the echo plane to reveal the internal cardiac structures. This study is an evaluation of the educational benefit of this application. ⋯ The large improvement in test scores during a short period of study and the high level of satisfaction across all of the disciplines indicates that the application is a useful adjunctive tool for learning TEE. It is now being used in TEE training worldwide.
