Novel Pharyngeal Oxygen Delivery Device Provides Superior Oxygenation during Simulated Cardiopulmonary Resuscitation.

Introduction: Passive oxygenation with non-rebreather face mask (NRFM) has been used during cardiac arrest as an alternative to positive pressure ventilation (PPV) with bag-valve-mask (BVM) to minimize chest compression disruptions. A dual-channel pharyngeal oxygen delivery device (PODD) was created to open obstructed upper airways and provide oxygen at the glottic opening. It was hypothesized for this study that the PODD can deliver oxygen as efficiently as BVM or NRFM and oropharyngeal airway (OPA) in a cardiopulmonary resuscitation (CPR) manikin model.

Canine Prostate Cancer: Current Treatments and the Role of Interventional Oncology.

Prostate carcinoma is one of the most common cancers worldwide in men, with over 3 million men currently living with prostate carcinoma. In men, routine screening and successful treatment schemes, including radiation, prostatectomy, or hormone therapy, have allowed for high survivability. Dogs are recognized as one of the only mammals to spontaneously develop prostate neoplasia and are an important translational model.

Changing the Culture: Increasing and Sustaining Anesthesiology Resident Physician Publication Rates.

Background: Academic inquiry is foundational to the advancement of medicine and resident training and must be demonstrated to the Accreditation Council for Graduate Medical Education. Past attempts at increasing publication rates have failed to identify educational best practice models. Our aim was to increase resident publication rates via culture and value changes that are universally implementable, affordable, effective, and sustainable.

Veterinary Interventional Oncology.

Interventional oncology (IO) is a rapidly growing field in veterinary medicine and has been accepted as a fourth pillar of treatment of neoplastic disease with other modalities including surgery, chemotherapy, and radiation therapy. The major categories of IO therapies in companion animals are focused on the use of locoregional therapies and stenting of malignant obstructions. Although significant assessment of veterinary IO techniques is still necessary, early evaluation of these varying techniques is demonstrating promising results.

Pharyngeal oxygen delivery device sustains manikin lung oxygenation longer than high-flow nasal cannula.

Purpose: Hypoxemia during a failed airway scenario is life threatening. A dual-lumen pharyngeal oxygen delivery device (PODD) was developed to fit inside a traditional oropharyngeal airway for undisrupted supraglottic oxygenation and gas analysis during laryngoscopy and intubation. We hypothesized that the PODD would provide oxygen as effectively as high-flow nasal cannula (HFNC) while using lower oxygen flow rates.

A Systematic Review of Canine Cystectomy: Indications, Techniques, and Outcomes.

This review provides a summary of the literature encompassing partial and total cystectomy procedures in dogs and subsequent conclusions that can be drawn. Surgical excision as a component of treatment for lower urinary tract neoplasia in dogs may enhance survival time and result in acceptable quality of life, though risk for surgical complications is substantial, particularly following total cystectomy procedures. However, for dogs with urothelial carcinoma, cystectomy is generally not considered curative and disease progression is common.

Arterial Cannulation Near-Miss During Jugular Venous Catheterization With Carotid Artery Aneurysm: A Case Report.

Central venous catheterization is a common procedure that may lead to inadvertent arterial cannulation, potentially causing bleeding, hematoma, stroke or rarely, death. In this near-miss case presentation, an aneurysmal carotid artery was misidentified with ultrasound by a junior resident, nearly leading to placement of a sheath into the artery. This case highlights arterial punctures that still occur even with ultrasound guidance.
