Cannot intubate/cannot ventilate (CICV) situations during anesthesia are rare, potentially catastrophic to the patient, and difficult to predict. Widely adopted practice guidelines advocate an algorithmic approach to CICV situations in which the anesthetist: (a) recognizes the CICV situation, (b) calls for help, (c) steadily progresses through a variety of methods to ventilate the patient and secure the airway, (d) restores ventilation via an infraglottic airway if the patient cannot be safely awakened prior to becoming moribund. Despite widespread consensus that rapid progression to placement of an infraglottic airway is critical to the survival of the patient in a CICV situation, the rarity of CICV is a substantial barrier for anesthetists attempting to gain and maintain skill at placing infraglottic airways. ⋯ These findings have implications for how nurse anesthetists should learn and sustain the skill of infraglottic airway placement. Nurse anesthetists should undergo initial training that requires the repetitive placement of infraglottic airways, and receive sustainment training every 6 to 12 months thereafter. Although rarely used, the skill of an anesthetist in infraglottic airway placement can mean the difference between life and death for the patient in a CICV situation.

Review Comparative Study
The Neurotoxicity of General Anesthetic Drugs: Emphasis on the Extremes of Age.
A substantial body of research suggests that anesthetic exposure to patients who are very young or very old may impair cognitive, behavioral, and emotional development or recovery. In lower animal models of pre- and postnatal age, anesthetic exposure may impact inflammation, synaptogenesis, neuronal apoptosis, and glial cell development. To date, research in humans is inconclusive regarding the long-term cognitive and behavioral sequelae of general anesthesia in the young child. ⋯ Existing neurological degenerative processes and other comorbidities in combination with the stress of surgery make evaluating the independent impact of anesthetic exposure difficult. Advances in research, imaging, and partnerships have enhanced the potential for understanding the impact of anesthetic exposure. In both populations, the resulting data and limitations faced in initial research efforts are catalysts for current prospective studies.

Symptom management research is a core area of nursing science and one of the priorities for the National Institute of Nursing Research, which specifically focuses on understanding the biological and behavioral aspects of symptoms such as pain and fatigue, with the goal of developing new knowledge and new strategies for improving patient health and quality of life. The types and volume of data related to the symptom experience, symptom management strategies, and outcomes are increasingly accessible for research. Traditional data streams are now complemented by consumer-generated (i.e., quantified self) and "omic" data streams. ⋯ The purposes of this chapter are to (a) briefly summarize the current drivers for the use of big data in research; (b) describe the promise of big data and associated data science methods for advancing symptom management research; (c) explicate the potential perils of big data and data science from the perspective of the ethical principles of autonomy, beneficence, and justice; and (d) illustrate strategies for balancing the promise and the perils of big data through a case study of a community at high risk for health disparities. Big data and associated data science methods offer the promise of multidimensional data sources and new methods to address significant research gaps in symptom management. If nurse scientists wish to apply big data and data science methods to advance symptom management research and promote health equity, they must carefully consider both the promise and perils.

Traumatic brain injury (TBI) is the leading cause of mortality and morbidity in the younger population worldwide. Survivors of TBI often experience long-term disability in the form of cognitive, sensorimotor, and affective impairments. ⋯ However, no effective treatment for TBI has been established to date in the clinical setting, despite promising results generated in preclinical studies in the use of neuroprotective strategies. The failure to translate results from preclinical studies to the clinical setting underscores a compelling need to revisit the current state of knowledge in the use of animal models in TBI.

Traumatic brain injury (TBI) in all of its forms--blast, concussive, and penetrating--has been an unfortunate sequela of warfare since ancient times. The continued evolution of military munitions and armor on the battlefield, as well as the insurgent use of improvised explosive devices, has led to blast-related TBI whose long-term effects on behavior and cognition are not yet known. Advances in medical care have greatly increased survival from these types of injuries. ⋯ This review focuses on specific aspects of military-related TBI. There exists a large body of literature reporting the environmental conditions, forces, and staging of injury. Many of these studies are focused on the neuropathology of TBI, due to blast overpressure waves, and the emergence of large numbers of mild blast-related TBI cases.
