How Long Must We Wait? A Review Of Adherence To Established Npo Guidelines, Ellen C. Bouaziai, Anthony S. Hernandez, Shashi Sahai, Kerry Peters Mychaliska

Conference Presentation Abstracts

Background: Patients undergoing a procedure with anesthesia are required to be nil per os (NPO) for a defined period to reduce the risk of aspiration of gastric contents. In 2017, the American Society of Anesthesiologists (ASA) published guidelines for preoperative fasting, which allow for consumption of a full meal 8 hours before a procedure; non-human milk, light meal, and infant formulas 6 hours prior; breastmilk 4 hours prior; and clear liquids 2 hours prior to procedure. It is well known that these NPO guidelines are inconsistently applied to pediatric patients. The purpose of this study is to determine the percentage …

Historical Perspectives On Bloodletting In The Management Of Asthma In Children And Adults, Joudeh B. Freij, Bishara J. Freij

Conference Presentation Abstracts

Background: Current asthma management consists of a combination of drugs with different mechanisms of action. Ancient asthma care, by contrast, focused on loosening the humours using remedies such as drinking animal blood, eating rabbit fat and fox lungs, inhaling or consuming certain herbs and plants, bloodletting (including wet cupping), diet (eating raisins, dried figs, vegetables, barley, capers, bread, cake), steaming, baths, wet compresses, and moderate helpings of wine with dinner. Bloodletting was believed to purge the body of noxious humours that caused human disease and thereby reduce inflammation. Here we address the use of bloodletting in asthma management over the …

Operative Vs. Non-Operative Treatment Of Z-Type Clavicle Shaft Fractures In Adolescents: A Retrospective Study, Iulio Dobrin, Colin Van Wagoner, Ehab Saleh

Conference Presentation Abstracts

OBJECTIVE: Clavicle fractures are common in both adult and pediatric populations.1 Yet, the literature describes differences regarding treatment in such fractures between these populations, favoring operative treatment for adults and nonoperative treatment for pediatric patients.2 There is particular uncertainty for treating a subgroup of adolescent clavicle fractures known as the Z-type comminuted fracture which, being a completely displaced and complex fracture pattern, can prove to have different healing rates than other midshaft clavicle fractures. Because of concerns about healing and bony prominences, these types of fractures are commonly treated surgically, despite an increasing body of literature indicating equivalent outcomes in …

Intraoperative Code Status: Moving From Misinformation To Respect For Patient Autonomy, Jacob Applegarth, Jacob M. Morton, Nathan M. Novotny, Ngan Nguyen, Abram Brummett

Conference Presentation Abstracts

Introduction: Intraoperative code status represents a complicated topic for patients and providers. Prior studies demonstrated a lack of understanding of intraoperative code status, specifically do not resuscitate (DNR) orders. This misunderstanding appears common despite clear professional recommendations. A recent survey of surgery residents at our institution showed variability in understanding of intraoperative code status policy despite clear institutional guidelines. Few studies utilized simulated education for surgeons and surgical residents to navigate intraoperative DNR status. This project aims to create a simulation-based program for residents to navigate intraoperative DNR status ethically and to assess its impact on learning, practice patterns and …

Posters

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis affecting medium-sized arteries, involving multiple organs, with the most frequently affected tissues being skin and peripheral nerves (1). The distinct pearl neckless pattern led to the naming of this condition (2). Cutaneous polyarteritis nodosa (CPAN) is a variant of PAN confined to the skin, muscles and peripheral nerves in the absence of any systemic involvement (1). This rare form of systemic necrotizing vasculitis is limited to the medium-sized arteries of the skinand has a more favorable prognosis (1). PAN is also linked to Hepatitis B(2).The current diagnostic criteria for CPAN were proposed …

Repair Of Achilles Tendon Re-Rupture With Fhl Transfer: A Case Study, Taylor Allison, Joshua Kazdan

Posters

The Achilles tendon consists of the soleus muscle and two heads of the gastrocnemius muscle. Loss of its function can result in loss of plantarflexion strength, which can impact activities of daily living. In a study by Scheller et al, Achilles tendon ruptures were missed on initial evaluation on 25% of their patients. Other studies have reported a similar incidence of misdiagnoses. Patients may also delay treatment due to decreased pain after the initial injury. Ruptures diagnosed 4 weeks from injury are often considered chronic, and many of these patients benefit from surgical repair. A flexor hallucis longus (FHL) transfer …
