Surgical Site Infiltration: A Neuroanatomical Approach
Publication date: Available online 25 July 2019Source: Best Practice & Research Clinical AnaesthesiologyAuthor(s): Girish P. Joshi, Anthony MachiAbsractLocal anaesthetic administration into a surgical wound blocks the noxious stimuli that result from surgical insult at the site of origin. Surgical site infiltration (also known as local infiltration analgesia) is easy to perform, safe, and inexpensive. In addition, it avoids motor blockade, which is particularly relevant for lower limb surgery. The best approach to surgical site infiltration includes meticulous, systematic and extensive surgical site local anaesthetic infil...

Best Practice & Research Clinical Anaesthesiology: Advances in haemodynamic monitoring for the peri-operative patient Perioperative cardiac output monitoring
Publication date: Available online 22 July 2019Source: Best Practice & Research Clinical AnaesthesiologyAuthor(s): Berthold Bein, Jochen RennerAbstractLess invasive or even completely non-invasive haemodynamic monitoring technologies have evolved during the last decades. But even established, invasive devices such as the pulmonary artery catheter and transpulmonary thermodilution have still an evidence-based place in the perioperative setting, albeit only in special patient populations. Accumulating evidence suggests to use continuous haemodynamic monitoring, specifically flow-based variables such as stroke volume or cardi...

Why and how to assess cerebral autoregulation?
Publication date: Available online 22 July 2019Source: Best Practice & Research Clinical AnaesthesiologyAuthor(s): Annelies Moerman, Stefan De HertAbstractAround the turn of the century, a better understanding of the complex physiology of cerebral blood flow regulation has emerged. It is now acknowledged that cerebral autoregulation is much more complicated than we previously thought it was, with the shape of the autoregulation curve and limits of autoregulation that may vary enormously and unpredictably, both within and between patients. The consequence is that in order to safeguard the cerebral circulation, the dogma tha...

Perioperative hemodynamic monitoring: still a place for cardiac filling pressures ?
Publication date: Available online 22 July 2019Source: Best Practice & Research Clinical AnaesthesiologyAuthor(s): Christian Schmidt, Astrid Ellen Berggreen, Matthias HeringlakeAbstractThe clinical usefulness of the so-called “static” cardiac filling pressures - central (CVP) and pulmonary-artery-occlusion-pressure (PAOP) – has come into question for guiding hemodynamic therapy due to their poor ability to predict fluid responsiveness in comparison with other monitoring modalities like transpulmonary thermodilution derived volumetric measurements, dynamic variables for assessing fluid responsiveness, and the potentia...

Peripheral nerve catheters: A critical review of the efficacy
Publication date: Available online 22 July 2019Source: Best Practice & Research Clinical AnaesthesiologyAuthor(s): Rasmus W. Hauritz, Kjartan E. Hannig, Angela Lucia Balocco, Gwendolyne Peeters, Admir Hadzic, Jens Børglum, Thomas F. BendtsenAbstractContinuous peripheral nerve blocks are commonly used for postoperative analgesia after surgery. However, catheter failure may occur due to either primary (incorrect insertion) or secondary reasons (displacement, obstruction, disconnection). Catheter failure results in unanticipated pain, need for opioid use, and risk of readmission or delay in hospital discharge. This review ai...

Post-Operative Ward Monitoring – Why & What Now?
Publication date: Available online 23 July 2019Source: Best Practice & Research Clinical AnaesthesiologyAuthor(s): Ashish K. Khanna, Sanchit Ahuja, Robert Weller, Timothy N. HarwoodAbstractThe postoperative ward is considered an ideal nursing environment for stable patients transitioning out of the hospital. However, about half of all in-hospital cardiorespiratory arrests occur here and are associated with poor outcomes. Current monitoring practices on the hospital ward mandate intermittent vital signs checks. Subtle changes in vital signs often occur at least 8-12 hours prior to an acute event, and continuous monitoring o...

Burns, Karina Charipova, Kyle L. Gress, Rachel J. Kaye, Matthew R. Eng, Elyse M. Cornett, Alan David KayeAbstractRegional anesthetic techniques are important components of successful multimodal analgesic strategies. When used successfully, truncal nerve blocks of the chest wall, abdomen, and, paraneuraxial nerves, in combination with other analgesic modalities, may offer similar analgesic efficacy as neuraxial techniques, which are associated with a gr...
