Electronic cigarettes are essentially electronic nicotine delivery systems (ENDS). Use of ENDS has increased sharply in the United States in recent years, particularly among youth. We reviewed the literature on ENDS use, based on a PubMed search, with a focus on effects that could influence anesthetic and surgical outcomes. We also included a meta-analysis of articles published between 2016 and 2018 reporting injuries from exploding ENDS. These devices deliver nicotine, which is addictive and a cardiac stimulant. The nicotine in ENDS has been linked to increased risk of heart disease and myocardial infarction. Also, ENDS deliver vapors of solvents, flavorings, and other chemicals that can cause chronic and acute respiratory diseases. Furthermore, ENDS use may pose a cancer risk. However, ENDS are somewhat less dangerous than cigarettes and are used as smoking cessation devices. From the literature review, we identified 15 articles reporting injuries from ENDS fires and explosions to 93 patients. Most of these patients were young (mean age = 31.6 years) and male (91%). Afuresertib in vitro The most common injury sites were the thigh (62%) and hand (33%). Because the anesthetist will likely encounter increasing numbers of ENDS users in the future, it is important to identify these patients and to understand the risks of ENDS use.

The patient's perioperative course was otherwise uncomplicated, with the subcutaneous emphysema developing at surgical closure. The patient presented with substantial crepitus spanning from her face to her lower extremities and hypercarbia with end-tidal carbon dioxide readings persistent between 60 and 70 mm Hg. This case did not result in clinically significant airway obstruction because of provider vigilance. However, undiagnosed subcutaneous emphysema without a secured airway may lead to respiratory distress, respiratory depression, airway obstruction, tracheal deviation, and tension pneumothorax.

Traditional oral airways (TOAs, made of rigid plastic) or nasal airways (made of pliable materials) can be associated with adverse effects, contributing to a trend of anesthesia providers placing nasal airways orally. A clinical observational study and an electronic provider survey were conducted to examine this emerging practice. The observation study objective was to investigate reported postoperative sore throat occurrence associated with use of either a nontraditional airway (nasal airway used orally) or TOA in deep sedation procedures (N = 243). Patients receiving nontraditional airways reported significantly less postoperative sore throat than those receiving TOAs (17% vs 40%, respectively; P less then .001). These results prompted a broader exploration into airway practices of anesthesia providers via an electronic survey. Most respondents (n = 293) reported adverse effects, including gagging/coughing on insertion, oral cavity injury, and bleeding with TOAs. More than half (52.8%) reported using nasal airways orally. These results suggest a clinical void in current airway management options for deep sedation. Providers indicated the need for airway devices that provide a patent airway while mitigating adverse effects associated with commonly used airways.

Cricothyrotomy is the final step, but anesthesia training and maintenance of surgical airway skills is variable. The ability to "cut to air" when one performs a cricothyrotomy may be all that prevents a patient from experiencing anoxic brain injury or death. Forty-three Certified Registered Nurse Anesthetists (CRNAs) performed emergency cricothyrotomies on a simulation manikin. Three techniques were available (1) cricothyrotomy kit, (2) scalpel and tracheostomy, and (3) scalpel/bougie/endotracheal tube. Technique selection and performance were recorded until successful confirmation of placement was achieved in less than 2 minutes. Confidence levels performing cricothyrotomy were also measured before and after simulation. Most CRNAs (53.5%) selected the cricothyrotomy kit, and all but 1 completed the cricothyrotomy in under 2 minutes. The scalpel/bougie/endotracheal tube combination was the fastest, with an average completion time of 86.6 seconds. The confidence of CRNAs in performing a successful cricothyrotomy in less than 2 minutes was significantly increased (P ≤ .001). Simulating airway skills improved performance, speed, and confidence. Because not all CRNAs have had extensive education in performing surgical airways and practicing these skills, simulation may have additional value in developing and maintaining skills and confidence.

The purpose of this project was to determine if ultrasonography could be routinely used to measure gastric content and assign aspiration risk in patients undergoing general anesthesia. Preoperative gastric ultrasonography was performed in a convenience sample of 100 patients. A group of Certified Registered Nurse Anesthetists, anesthesia residents, and anesthesiologists were asked their plan for airway management before and after receiving the results of the patients' gastric ultrasonogram, to determine if the scan would alter the plan. In 14% of patients scanned, solid gastric content was observed, 7% had clear liquids present, and 79% had an empty stomach. Of the patients with clear liquids present, 3 had substantial (> 100 mL) gastric content despite following fasting guidelines. Overall, there was a 9% change in airway management from standard induction 6% changed to modified rapid sequence intubation (no ventilation, no cricoid pressure), and 3% changed to rapid sequence intubation with cricoid pressure.
