Safety and efficacy of epidural analgesia.

Purpose of review: Epidural analgesia remains a widely used analgesic technique. This article aims to assess the safety of epidural analgesia by balancing efficacy and complications, of epidural analgesia for acute, labor and chronic pain. Recent findings: Main indications for epidural analgesia include major open abdominal surgery, thoracotomy and labor analgesia. Past and current literature show that epidural analgesia leads to statistically significant, but possibly clinically less meaningful, reductions in pain scores compared with intravenous analgesia. The debate continues whether epidural analgesia leads to decreased complications and improved outcome. Noninferiority of alternative regional analgesic approaches, that is continuous-wound-infiltration, peripheral nerve blocks or surgical site infiltration, appears to be present and is promising for the future. Serious adverse events after epidural analgesia seem to occur more often than was previously thought and clinicians must realize that incidence rates differ in specific perioperative patient populations. Summary: Epidural analgesia for obstetric analgesic purposes is considered to be well tolerated in young, healthy women, since efficacy has been proven and complications leading to permanent neurological damage seldomly occur. Safety of epidural analgesia for perioperative and chronic pain treatment is more difficult to balance; careful selection of appropriate patients cannot be over-emphasized.

New advancements in spinal cord stimulation for chronic pain management.

Purpose of review: To update the recent development of spinal cord stimulation (SCS) technology in the management of chronic pain. Recent Findings: Efficacy of SCS therapy has been significantly improved by the recent development of high frequency (HF-10 kHz) stimulation, burst stimulation, and dorsal root ganglion (DRG) stimulation. A few latest SCS modalities are in clinical trial. New approaches to guide lead placement and advances in surgical lead are introduced. Summary: HF-10 SCS is free of paresthesia and associated with significantly better coverage of axial lower back pain. Burst stimulation invokes minimal paresthesia and provides better coverage of low back pain. DRG stimulation results in better outcomes in patients with complex regional pain syndrome. It requires less energy and delivers consistent stimulation regardless of postural variations. Clinical trials with new SCS modalities, such as Stimwaves, are under way to make SCS wireless. Intraoperative neuromonitoring and paresthesia atlas may be used to guide lead placement. Multicolumn surgical paddle leads enable a combination of independent current control with up to 32 contacts for better programming and better coverage.

Nonoperating room anesthesia for endoscopic procedures.

Purpose of review: The purpose of this review is to take a look on some practical aspects of anesthetic care in the endoscopy suite, concerning the general approach, safety, and monitoring issues. Recent findings: Concerning propofol popularity for sedation during endoscopic procedures new studies create doubt in the safety of higher doses of propofol used for sedation. Careful titration of propofol, addition of synergistic supplements like ketamine and dexmedetomidine, and monitoring of anesthetic depth may limit the dose of propofol given to the patients. Capnography has the potential to detect airway compromise earlier than pulse-oximetry and by this enhancing patient safety. Summary: Sedation or anesthesia in the endoscopy suite is not without risk. For complex and longer lasting procedures and in patients with significant comorbidities and risk factors, good clinical judgment, built on experience, is essential and to foster this, it seems prudent to build up a group of anesthesiologists dedicated to a special sedation service.

Enhancing the quality and safety of the perioperative patient.

Purpose of review: Many possible hazards bedevil the perioperative patient. This review focuses on a number of aspects of perioperative management where the patient's quality and safety can be enhanced. Recent findings: Our understanding of the relationship between preoperative preparation and postoperative outcomes has improved. There have also been recent developments in our understanding of how to construct useful cognitive aids and make the best use of checklists by understanding the cultural environment supporting their use. Postoperatively, the concept of 'failure to rescue' in the surgical patients has been explored. Summary: A clear vision of what postoperative recovery should mean for practitioner and patients; careful risk stratification and prophylactic measures to avoid postoperative complications; the judicious use of checklists and other cognitive aids to complement clinical expertise in promoting safety within each local context; and the prompt recognition and rescue of postoperative problems when they occur are all important aspects of a safe perioperative care.

Optimizing education in difficult airway management: meeting the challenge.

Purpose of review: The last 2 decades have seen a vast change in the science and technology of airway management. As a result, there is an increasing need to equip anesthesiologists with the new knowledge and skills for the safe management of a difficult airway. Recent findings: In addition to knowledge and expertise, human factors and nontechnical skills (NTS), including situational awareness, communication and team work, play an important role during difficult airway management and contribute to the outcome. Didactic sessions are useful to impart knowledge. Self-learning, interactive discussions, simulation and debriefing are important tools for teaching and training in difficult airway management. Manikin training and simulation enable development of technical as well as NTS without subjecting patients to risk and allow multiple training sessions of relatively uncommon scenarios. Guidelines are useful teaching tools, whereas cognitive tools such as the Vortex approach may be useful during a difficult airway. Summary: There is need for research on difficult airway management and optimized training methods. Research is also required to determine the barriers to adoption of guidelines and strategies to ensure widespread dissemination and implementation of guidelines and best practices for difficult airway management.

Are we fully utilizing the functionalities of modern operating room ventilators?.

Purpose of review: The modern operating room ventilators have become very sophisticated and many of their features are comparable with those of an ICU ventilator. To fully utilize the functionality of modern operating room ventilators, it is important for clinicians to understand in depth the working principle of these ventilators and their functionalities. Recent findings: Piston ventilators have the advantages of delivering accurate tidal volume and certain flow compensation functions. Turbine ventilators have great ability of flow compensation. Ventilation modes are mainly volume-based or pressure-based. Pressure-based ventilation modes provide better leak compensation than volume-based. The integration of advanced flow generation systems and ventilation modes of the modern operating room ventilators enables clinicians to provide both invasive and noninvasive ventilation in perioperative settings. Ventilator waveforms can be used for intraoperative neuromonitoring during cervical spine surgery. Summary: The increase in number of new features of modern operating room ventilators clearly creates the opportunity for clinicians to optimize ventilatory care. However, improving the quality of ventilator care relies on a complete understanding and correct use of these new features. Video abstract: http://ift.tt/2hpXORl.
