Randomized Controlled Trial Comparative Study
Comparison of Successful Intubation Between Video Laryngoscopy View Before Attempted Intubation and Direct Laryngoscopic Intubation by Student Registered Nurse Anesthetists: A Pilot Study.
Airway management is a primary focus when student registered nurse anesthetists (SRNAs) begin clinical rotations in their nurse anesthesia program. Successful endotracheal intubation requires both knowledge of and experience with the airway and its structures. Lack of clinical maturity and unfamiliarity with the patient airway intensifies student anxiety in the clinical arena. ⋯ This study required group 1 to perform direct laryngoscopy in their first clinical opportunity in the operating room; group 2 was required to observe a minimum of 3 video laryngoscopic (GlideScope, Verathon Inc) intubations performed by the clinical preceptor before the students' first attempt using direct laryngoscopy. Other modalities used to secure the airway in this study included the GlideScope and a laryngeal mask airway. Results of the data analysis revealed there was no significant difference between groups for success of direct laryngoscopy (group 1, 54%; group 2, 58%; P = .45).

The objective of this study was to investigate whether patients' sense of coherence (SOC)--ability to comprehend their whole situation and their capacity to use available resources--influences acute postoperative complications in the postanesthesia care unit (PACU). We hypothesized that patients' SOC would be negatively related to their experience of pain and nausea, consumption of opioids, and length of stay in the PACU--the higher the SOC, the lower the experience of pain and nausea, less consumption of opioids, and shorter PACU stay. Data were collected from the anesthesia and electronic medical records, and combined with a questionnaire. ⋯ Patients with a stronger SOC experienced significantly less pain (P < .01) and consumed significantly less opioids (P < .01) than those with a lower SOC. Patients' SOC influences their experience of pain and opioid consumption in the PACU. Therefore, patients' SOC could be one of many factors that nurse anesthetists consider in their efforts to predict, prevent, and decrease patients' experience of pain in the PACU.

Historical Article
Discovery of Modern Anesthesia: A Counterfactual Narrative about Crawford W. Long, Horace Wells, Charles T. Jackson, and William T. G. Morton.
The discovery of anesthesia occurred during a narrow time span in the mid-19th century, but there is no agreement about who deserves credit for this important American contribution to medicine. Based mostly on an examination of primary sources, we explore how formal and informal interactions between the principals affected their careers, lives, and attribution of credit for the discovery of anesthesia. There should be no controversy as to which individual deserves credit for the discovery of anesthesia if credit is ascribed for specific contributions. ⋯ Charles T. Jackson suggested the use of ether as an anesthetic agent to Morton. We also assert that had these individuals not known one another, the discovery of anesthesia would have proceeded in approximately the same timeframe, but Wells, Morton, and Jackson would have enjoyed more productive careers as well as longer, more peaceful lives.

Occasionally intubation of patients is difficult using a video laryngoscope (GlideScope, Verathon Medical) because of an inability to guide the endotracheal tube to the glottis or pass the tube into the trachea despite an adequate view of the glottis. We examined methods to improve success when this difficulty occurs. A literature search revealed 253 potential sources, with 25 meeting search criteria: 7 randomized controlled trials, 4 descriptive studies, 8 case series, and 6 case reports. ⋯ Evidence from lower-level sources suggested that several interventions were helpful, including using a controllable stylet, a fiberoptic bronchoscope in conjunction with the GlideScope, or an intubation guide, and twisting the endotracheal tube to facilitate passage into the trachea. Providers must consider the risks and benefits of any technique, particularly if the device manufacturer does not recommend the technique. Further rigorous investigations should be conducted examining methods to increase success.
