Hyperbaric oxygen therapy and fluorescence angiography in arterial insufficiency secondary to injection of crushed hydromorphone.

Introduction: Foreign body emboli can lead to acute arterial insufficiency. We present a case report of upper extremity arterial insufficiency in an intravenous (IV) drug user secondary to intra-arterial injection of crushed tablet particles successfully treated with hyperbaric oxygen (HBO2) therapy.

Case: A 37-year-old right-hand-dominant male developed pain and swelling of the left hand after attempting to inject crushed hydromorphone tablets into his venous circulation.

Physiologic and biochemical rationale for treating COVID-19 patients with hyperbaric oxygen.

The SARS-Cov-2 (COVID-19) pandemic remains a major worldwide public health issue. Initially, improved supportive and anti-inflammatory intervention, often employing known drugs or technologies, provided measurable improvement in management. We have recently seen advances in specific therapeutic interventions and in vaccines.

ARTERIAL INSUFFICIENCIES: Hyperbaric Oxygen Therapy for Selected Problem Wounds.

The use of hyperbaric oxygen (HBO2) for the treatment of selected problem wounds has focused almost entirely on the diabetic foot ulcer (DFU) in recent years. The prevalence of DFUs in today's patient population and the reimbursement available for the treatment of DFUs have given it priority status in discussions about problem wounds, but there are sound fundamental reasons why additional oxygen may have benefits in the treatment of non-DFU wounds.

Safety of a continuous glucose monitoring device during hyperbaric exposure.

Background: Hyperbaric oxygen therapy has been demonstrated to lower blood glucose levels in patients with diabetes. Continuous glucose monitoring (CGM) allows glucose monitoring in real time. Battery-operated CGM transmitters have yet to be formally tested and given safety approval for use in a hyperbaric environment.

Reliability of the Dexcom G6 Continuous Glucose Monitor During Hyperbaric Oxygen Exposure.

People with diabetes-related ulcers may benefit from hyperbaric oxygen (HBO) therapy and from continuous glucose monitors (CGM). Although blood glucose (BG) meters based on glucose oxidase (GO) report erroneously low values at high pO, BG meters based on glucose dehydrogenase (GD) do not. We therefore examined the performance of a GO-based CGM system in comparison to GO-based and GD-based BG systems in normobaric air (NBAir), hyperbaric air (HBAir), and HBO environments.

The effect of the prone maximal restraint position with and without weight force on cardiac output and other hemodynamic measures.

Background: The prone maximal restraint (PMR) position has been used by law enforcement and emergency care personnel to restrain acutely combative or agitated individual. The position places the subject prone with wrists handcuffed behind the back and secured to the ankles. Prior work has indicated a reduction in inferior vena cava (IVC) diameter associated with this position when weight force is applied to the back.

Severe sodium channel blockade and cardiovascular collapse due to a massive lamotrigine overdose.

Background: Cardiac arrest due to lamotrigine (LTG) has been reported after co-ingestion with bupropion, but severe sodium channel blockade in the absence of other toxins has not been described. We report a case of cardiac arrest and status epilepticus following a massive LTG overdose.

Case Report: A 48 year-old female was brought to the ED with seizure-like activity subsequent to ingesting 7.

Limited communication and management of emergency department hyperglycemia in hospitalized patients.

Background: Hyperglycemia is often overlooked and unaddressed in hospitalized patients, and early and intensive management may improve outcomes.

Objective: To evaluate communication and early management of emergency department (ED) hyperglycemia.

Methods: This was a retrospective cohort study of patients with an initial serum glucose >or=140 mg/dL at an urban, academic institution.
