“…98 As a result, other criteria generated in the 1970s did not mandate the use of an EEG to determine brain death. 99 Furthermore, it is well-established that there are limitations in interpretation of an EEG obtained in an intensive care unit due to the presence of equipment that produces significant artifact. 100 Powner et al also noted that patients can have persistent cranial nerve functioning despite the presence of an isoelectric EEG (such as in the setting of hydrocephalus, intoxication, hypothermia, metabolic encephalopathy), demonstrating that the clinical exam should always trump the ancillary test.…”

In 1968, the definition of death in the United States was expanded to include not just death by cardiopulmonary criteria, but also death by neurologic criteria. We explore the way the definition has been modified by the medical and legal communities over the past 50 years and address the medical, legal and ethical controversies associated with the definition at present, with a particular highlight on the Supreme Court of Nevada Case of Aden Hailu.

“…Helpful signs that distinguish retroperitoneal gas include accentuation of the lateral border of the psoas muscle medially and a lucent silhouette effect around the kidney (Figs 7,8). However, gas that results from barotrauma often dissects within both spaces and is present in both simultaneously [42] (Fig 9). The clinician must explore a differential diagnosis to define causes of such gas collections, which in the ICU include ruptured abdominal viscus, infection, pneumatosis cystoides intestinalis, or iatrogenic procedures [40].…”

Disruption of lung parenchyma by airway gas (baro trauma) frequently occurs in the intensive care unit. Gas may move from the airspace into several abnormal loca tions as a result of dissection along anatomical fascial planes to potentially produce interstitial emphysema, subpleural cysts, pneumomediastinum, subcutaneous emphysema, pneumopericardium, pneumothorax, pneu moperitoneum, pneumoretroperitoneum, bronchopleu ral fistulas, and air-entry into blood vessels. Although usually of limited clinical consequence, this extra-alve olar air may produce clinically significant morbidity and mortality. Recognition of these potential complications of pulmonary disease and its therapy may assist the clini cian in correctly diagnosing, avoiding, and treating the manifestations of pulmonary barotrauma.

“…Air has been used for several invasive procedures and for treating various pathological conditions, for example, fiberesophagoscopy (Katz et al, ), bronchopulmonary dysplasia (Stahlman et al, ; Shenai et al, ), retroperitoneal dissection (Powner et al, ), and removal of pterygium (Gulkilik et al, ). The technique of deep lamellar keratoplasty with air injection into the corneal stroma was reported in 1985 (Chau et al, ).…”

Breathing Life into the Cadaver: Introducing Air Dissection As a New Teaching and Dissecting Method for the Venous System

Air insufflation has been used for various surgical procedures such as during laparoscopy. We hypothesized that the use of pressurized air might enable cadaveric dissection to differentiate smaller veins better than traditional dissection techniques. In three fresh-frozen cadavers, the inferior vena cava (IVC) and right or left femoral veins were exposed just distal to the inguinal ligament and a needle placed into one of them. Pressurized air was then placed into the cannulated femoral vein using an air compressor. In all specimens, the IVC and most of its tributaries, both left and right sides, were clearly insufflated. When the IVC was traced superiorly by resecting the diaphragm through the caval foramen, the right atrium and ventricle were also found to be dilated. Additionally, venous variants that would have not been obvious without dilatation of the IVC were identified. Air dissection of the venous system in fresh-frozen cadavers aids in anatomical dissection. Such a model might also serve as a surgical training model and teaching tool as it better mimics life-like anatomy and physiology. We term this technique "cadaveric air dissection." Clin.
