Anesthesia in the Korean War.

Relying on original, primary source documentation from the National Archives, we describe the practice of anesthesia in mobile army surgical hospital (MASH) units and the 171st Evacuation Hospital during the latter part of the Korean War in 1953. Values were scaled and reported as percentages. These Essential Technical Medical Data Sheets reveal a surprising proportion (12.9%) of men received spinal anesthetics, despite official recommendations to the contrary. Still, the majority (69.2%) of the wounded underwent general anesthesia, most commonly through a mixture of thiopental and nitrous oxide. Despite data from World War II demonstrating the advantages of endotracheal intubation in these patients, few patients (20.6%) were intubated. Six percent benefited from the new curare-based drugs. This is the first English-language article that describes the practice of anesthesia during the Korean War. Utilizing primary source documentation, we found that general anesthesia was the most common type utilized. Newer techniques were not as commonly adopted, despite official recommendations and data from the time. The care provided closely resembled that delivered in the Second World War but inspired a series of technological and pedagogical reforms through the 1950s to improve military anesthesia for the next conflict.

History of Medicine in the Clerkships: A Novel Model for Integrating Medicine and History.

The history of medicine has only unevenly been integrated into medical education. Previous attempts to incorporate the subject have focused either on the first year, with its already over-subscribed curriculum, or the fourth year in the form of electives that reach a small minority of students. Duke University provides an alternative model for other universities to consider. At our institution we have overcome many of the curricular limitations by including history during the mandatory third year clerkships. Reaching 100% of the medical school class, these sessions align with clinical disciplines, providing students a longitudinal perspective on what they are seeing and doing on the hospital wards. They are taught in conjunction with a medical history librarian and rely heavily on the utilization and interpretation of physical artifacts and archival manuscripts. The surgery, obstetrics/gynecology, and pediatrics rotations now feature successful and popular history of medicine sessions. Describing our lesson plans and featuring a list of both physical and online resources, we provide a model others can implement to increase the use, the framing, and the accessibility of history in their medical schools.

Medicine and History: a Surgical Model for National Integration.

Historians and physicians have struggled to incorporate history into American medical education for over a century. Most efforts focus on local initiatives targeting a narrow audience. We describe a novel method involving the American College of Surgeons, a national organization with tens of thousands of members. Capitalizing on its infrastructure and influence over the field, we have implemented a variety of ventures that include panel sessions at meetings, poster competitions, travel grants, themed breakfasts, online communities, and other such projects. This programming has reached thousands of participants, ranging from pre-medical students to retired physicians, and it has increased both the exposure to and production of surgical history. Our article describes the process of establishing this nationally coordinated enterprise in the hopes that other medical specialties can emulate it and further the study of and appreciation for medical history.

Biomedical Research in Times of Emergency: Lessons From History.

Coronavirus disease 2019 (COVID-19) has sickened millions, killed hundreds of thousands, and utterly disrupted the daily lives of billions of people around the world. In an effort to ameliorate this devastation, the biomedical research complex has allocated billions of dollars and scientists have initiated hundreds of clinical trials in an expedited effort to understand, prevent, and treat this disease. National emergencies can stimulate significant investment of financial, physical, and intellectual resources that catalyze impressive scientific accomplishments, as evident with the Manhattan Project, penicillin, and the polio vaccines in the 20th century. However, pressurized research has also led to false promises, disastrous consequences, and breaches in ethics. Antiserum in the 1918 flu epidemic, contaminated yellow fever vaccines in World War II, and unethical human experimentation with mustard gas offer just a few cautionary exemplars. It is critical to continue biomedical research efforts to address this pandemic, and it is appropriate that they receive priority in both attention and funding. But history also demonstrates the importance of treating early results-such as those associated with hydroxychloroquine-with caution as we only begin to understand the biology, epidemiology, and potential target points of COVID-19.

Vascular Surgery in the Pacific Theaters of World War II: The Persistence of Ligation Amid Unique Military Medical Conditions.

: Although multiple sources chronicle the practice of vascular surgery in the North African, Mediterranean, and European theaters of World War II, that of the Pacific campaign remains undescribed. Relying on primary source documents from the war, this article provides the first discussion of the management of vascular injuries in the island-hopping battles of the Pacific. It explains how the particular military, logistic, and geographic conditions of this theater influenced medical and surgical care, prompting a continued emphasis on ligation when surgeons in Europe had already transitioned to repairing arteries.

Robotic Inguinal Hernia Repair (TAPP) First Experience with the New Senhance Robotic System.

INTRODUCTION: This retrospective study was performed to evaluate the safety and feasibility of the new Senhance Robotic System (TransEnterix Inc., Morrisville, North Carolina) for inguinal hernia repairs using the transabdominal preperitoneal approach. MATERIALS AND METHODS: From March to September 2017, 76 inguinal hernia repairs in 64 patients were performed using the Senhance Robotic System. Patients were between 18 and 90 years of age, eligible for a laparoscopic procedure with general anesthesia, had no life-threatening disease with a life expectancy of less than 12 months, and a body mass index (BMI) < 35. A retrospective chart review was performed for a variety of pre-, peri-, and postoperative data including, but not limited to, patient demographics, hernia characteristics, and intraoperative and postoperative complications. RESULTS: Fifty-four male and 10 female patients were included in the study. Median age was 56.5 years (range 22-86 years), and median BMI was 25.9 kg/m2 (range 19.5-31.8 kg/m2). Median docking time was seven minutes (range 2-21 minutes), and median operative time was 48 minutes (range 18-142 minutes). Two cases were converted to standard laparoscopic surgery due to robot malfunction and abdominal wall bleeding, respectively. Median length of stay was one day. CONCLUSION: We report the first series of laparoscopic inguinal hernia repairs using the new Senhance Robotic System. Compared to conventional laparoscopic transabdominal preperitoneal (TAPP) hernia repairs, there was no significant difference in operative time or perioperative complications. Additionally, there was no significant learning curve detected due to its intuitive applicability. Therefore, the Senhance Robotic System promises broad applicability across a range of laparoscopic general surgical operations.

Battle of the Bulge: Aortic Aneurysm Management From Early Modernity to the Present.

For centuries, physicians have recognized aortic aneurysms as an acute threat to life. Therapeutic approaches to the disease began in the 18th century when leading physicians, such as René Laennec and Antonio Valsalva, applied research on circulation and blood coagulation to devise whole-body fasting and bleeding regimens to prevent rupture. After John Hunter's success in ligating arteries to treat peripheral aneurysms, surgeons attempted analogous operations on the aorta, but even the renowned Sir Astley Cooper and William Halsted met with disastrous results. Other clinicians tried various methods of creating intraluminal clots, including the application of such new technologies as electricity and plastic. Vessel repair techniques, pioneered by Alexis Carrel and others in the 20th century, eventually provided a reliably effective treatment. In the past few decades, minimally invasive methods that approach aneurysms endovascularly through small groin incisions have been adopted. A successful 2005 congressional campaign to fund screening for aortic aneurysms brought the disease to national attention and symbolizes current confidence in curing it. Drawing on various published and unpublished sources, this paper elucidates the development of specific treatments for aortic aneurysms over time and more broadly addresses how medicine and surgery apply the knowledge and technology available in particular eras to treat a specific, identifiable, and lethal disease. Examining the evolution of these therapeutic efforts unveils broader trends in the history of medicine. This allows aortic aneurysms to serve as a case study for exploring shifting philosophies in medical history.

The Education of American Surgeons and the Rise of Surgical Residencies, 1930-1960.

In the first half of the twentieth century, the training of American surgeons changed from an idiosyncratic, often isolated venture to a standardized, regulated, and mandated regimen in the form of the surgical residency. Over the three critical decades between 1930 and 1960, these residencies developed from an extraordinary, unique opportunity for a few leading practitioners to a widespread, uniform requirement. This article explores the transformation of surgical education in the United States, focusing on the standardization and dissemination of residencies during this key period. Utilizing the archives of professional organizations, it shows how surgical societies initiated and forced reform in the 1930s. It demonstrates the seminal and early role taken by the federal government in the expansion of surgical residencies through incentivized policies and, especially, the growth of the Veterans Administration health system after World War II. Finally, an examination of intra-professional debates over this process illustrates both the deeper struggles to control the nature of surgical training and the importance of residency education in defining the midcentury American surgeon.

Vascular Surgery in World War II: The Shift to Repairing Arteries.

Vascular surgery in World War II has long been defined by DeBakey and Simeone's classic 1946 article describing arterial repair as exceedingly rare. They argued ligation was and should be the standard surgical response to arterial trauma in war. We returned to and analyzed the original records of World War II military medical units housed in the National Archives and other repositories in addition to consulting published accounts to determine the American practice of vascular surgery in World War II. This research demonstrates a clear shift from ligation to arterial repair occurring among American military surgeons in the last 6 months of the war in the European Theater of Operations. These conclusions not only highlight the role of war as a catalyst for surgical change but also point to the dangers of inaccurate history in stymieing such advances.

Red blood cells mediate the onset of thrombosis in the ferric chloride murine model.

Application of ferric chloride (FeCl(3)) to exposed blood vessels is widely used to initiate thrombosis in laboratory mice. Because the mechanisms by which FeCl(3) induces endothelial injury and subsequent thrombus formation are little understood, we used scanning electron and brightfield intravital microscopy to visualize endothelial damage and thrombus formation occurring in situ. Contrary to generally accepted belief, FeCl(3) does not result in appreciable subendothelial exposure within the time frame of thrombosis. Furthermore, the first cells to adhere to FeCl(3)-treated endothelial surfaces are red blood cells (RBCs) rather than platelets. Energy dispersive x-ray spectroscopy demonstrated that ferric ions predominantly localize to endothelial-associated RBCs and RBC-derived structures rather than to the endothelium. With continuing time points, RBC-derived structures rapidly recruit platelets, resulting in large complexes that subsequently enlarge and coalesce, quickly covering the endothelial surface. Further studies demonstrated that neither von Willebrand factor nor platelet glycoprotein Ib-α receptor (GPIb-α) is required for RBCs to adhere to the endothelium, and that deficiency of GPIb-α greatly abrogated the recruitment of platelets to the endothelial-associated RBC material. These findings illuminate the mechanisms of FeCl(3)-mediated thrombosis and reveal a previously unrecognized ability of RBCs to participate in thrombosis by mediating platelet adhesion to the intact endothelial surface.

Vascular medicine and surgery in ancient Egypt.

Lauded alike by ancient civilizations and modern society, pharaonic Egyptian medicine remains an object of fascination today. This article discusses its surprisingly sophisticated understanding of a cardiovascular system. The term "cardiovascular system," however, carries assumptions and meanings to a modern audience, especially readers of this journal, which simply do not apply when considering ancient conceptions of the heart and vessels. For lack of better language, this article will use "cardiovascular" and similar terms while recognizing the anachronistic inaccuracy. After briefly summarizing ancient Egyptian medicine generally, it will review the anatomy, pathology, and treatment of the vasculature. The practice of mummification in ancient Egypt provides a unique opportunity for paleopathology, and the conclusion will explore evidence of arterial disease from a modern scientific perspective.

Medicine's Glass Slipper: The PAVAEX Boot and 20th Century Negative Pressure Therapy.

Before the 20th century, peripheral artery disease (PAD) manifested as extreme pain, chronic wounds, and, eventually, gangrene requiring amputation. Despite this, it was rarely diagnosed. However, at the turn of the century, Western medicine shifted focus from infectious to chronic illnesses, and with this change, physicians' engagement with PAD transformed. Aiming to mitigate long-term injury, physicians now worked to identify and treat vessel disease to restore meaningful blood circulation. This article explores the development and deployment of a new device resulting from this refocus, the PAssive VAscular EXerciser (PAVAEX) Boot, and its role as a creative response to a previously intractable clinical problem. The PAVAEX Boot, designed in 1933 by vascular surgeons Louis G. Herrmann and Mont R. Reid, was one of the few interventions for PAD at the time. Based on the observation that continuous negative pressure results in vasoconstriction, while short bursts transiently increase blood flow, the PAVAEX Boot utilized intermittent negative pressure to enhance peripheral vascular perfusion. Well-marketed and praised throughout the 1930s, it vanished from public writing and academic literature just 20 years later. However, negative pressure wound therapy resurged in the late 20th century, and though its inventors failed to recognize the precedent of the PAVAEX Boot, many of these devices and therapies are rooted in identical theories. We examine why the PAVAEX Boot faded from use and argue that the device remains a crucial advancement in negative pressure therapy.

Hilliard Seigler, M.D. and the origins of kidney transplantation and immunology at Duke.

The contributions of Dr. Hilliard Seigler to the founding of the Duke kidney transplantation program were considerable in both surgery and immunology. Some of these highlights are summarized based upon interviews with Dr. Seigler by the authors.

Richard Nixon's Left Knee and Its Impact on American History.

Richard Nixon injured his left knee in a limousine door while campaigning in North Carolina in 1960, resulting in septic arthritis that required a multi-day admission to Walter Reed Hospital. Still ill for the first presidential debate that fall, Nixon lost the contest based more on his appearance than his performance. Partly as a result of this debate, he was defeated by John F. Kennedy in the general election. Because of his leg wound, Nixon developed chronic DVTs in that limb, including a severe thrombus in 1974 that embolized to his lung, required surgery, and prevented him from testifying at the Watergate Trial. Episodes like this one highlight the value of studying the health of famous figures, where even the most minor injuries have the potential to influence world history.
