Anaesthesia in medical emergencies

Changing the Emergency Department's Practice of Rapid Sequence Intubation to Reduce the Incidence of Hypoxia

Rapid sequence intubation (RSI) is an advanced procedure performed by nurse practitioners in the emergency department (ED). Hypoxia is one of the most common complications associated with RSI, which may lead to serious sequela, including death. Hypoxia may result from medications that are given to facilitate the procedure or the underlying disease process. Without preventive measures, oxygen levels may fall rapidly when patients are no longer actively breathing. The incidence of RSI-induced hypoxia may be mitigated with proper education, preoxygenation, positioning, and the utilization of passive (apneic) oxygenation. The purpose of this project was to determine whether RSI practice could be changed through education and implementation of an evidence-based protocol in the ED of a hospital in south central United States. Baseline practice was determined by chart audits and compared with practice after educational sessions and protocol implementation. Change occurred as evidenced by an increase in the utilization of all 3 hypoxia prevention interventions included in the protocol. Staff education and utilization of a protocol changed the care provided, which can influence patient outcomes and decrease the incidence of RSI-induced hypoxia.

Ketamine use in current clinical practice

After nearly half a century on the market, ketamine still occupies a unique corner in the medical armamentarium of anesthesiologists or clinicians treating pain. Over the last two decades, much research has been conducted highlighting the drug's mechanisms of action, specifically those of its enantiomers. Nowadays, ketamine is also being utilized for pediatric pain control in emergency department, with its anti-hyperalgesic and anti-inflammatory effects being revealed in acute and chronic pain management. Recently, new insights have been gained on ketamine's potential anti-depressive and antisuicidal effects. This article provides an overview of the drug's pharmacokinetics and pharmacodynamics while also discussing the potential benefits and risks of ketamine administration in various clinical settings.

Ketamine: use in anesthesia

The role of ketamine anesthesia in the prehospital, emergency department and operating theater settings is not well defined. A nonsystematic review of ketamine was performed by authors from Australia, Europe, and North America. Results were discussed among authors and the final manuscript accepted. Ketamine is a useful agent for induction of anesthesia, procedural sedation, and analgesia. Its properties are appealing in many awkward clinical scenarios. Practitioners need to be cognizant of its side effects and limitations.
