Background: Coronavirus disease 2019 (COVID-19) pneumonia remains a major public health concern. The prognostic efficacy of Peripheral Perfusion Index (PPI) has been researched in different pathologies such as trauma and sepsis. We hypothesized that PPI may serve as predictor of mortality in hospitalized patients with COVID-19 infection.

Antivenom administration is the cornerstone of therapy, meticulous patient selection is needed because of the possible side effects of the antivenom including anaphylaxis. Peripheral perfusion index (PPI) is a simple, non-invasive test that is widely used for the detection of peripheral hypoperfusion.
View Article and Find Full Text PDFBackground: Despite global prevention and quarantine efforts, the incidence of COVID-19 disease continues to increase. As a possible cause, our aim was to investigate which parameters increase the sensitivity or protection against COVID-19 between RT-PCR positive and RT-PCR negative cases in patients admitted to the emergency department.
Methods: In the pandemic process, patients admitted to the hospital with suspicion of COVID-19 were evaluated retrospectively.
Purpose: The purpose of this study was to investigate the clinical use of copeptin to evaluate migraine attacks in the Emergency Department. An additional aim was to detect changes in serum copeptin levels in migraine patients during attack and attack-free periods.
Methods: This prospective case-control study included 52 migraine patients and 51 healthy individuals with similar demographic characteristics.
BACKGROUND High-flow nasal cannula (HFNC) is an alternative to conventional normobaric oxygen therapy (NBO) for hypoxemic patients. Since nothing is known about its effect on carbon monoxide (CO) poisoning, we hypothesized that HFNC might be a useful device in the treatment of CO poisoning victims. MATERIAL AND METHODS We retrospectively reviewed the medical records of patients who were admitted consecutively to the emergency department with CO intoxication.

Methods: Patients hospitalized in an emergency intensive care unit with a diagnosis of systemic inflammatory response syndrome were classified as having sepsis (n = 28), septic shock (n = 8), or severe sepsis (n = 8) according to International Sepsis Guidelines (old criteria). Forty-four patients were classified as having sepsis (n = 4), septic shock (n = 30), or infection (n = 10) according to The Third International Consensus Definitions for Sepsis and Septic Shock (new criteria).
Objective: The aim in this study was to compare the ultrasound estimation of the jugular vein diameter (IJVmax, IJVmin) and area (IJVarea), the height of the right internal jugular vein (CVPusg), the vena cava diameter (IVCmax, IVCmin), and the vena cava index (IVCindex) with direct estimation of central venous pressure (CVPinv).
Methods: Ultrasonography was performed on 37 nonventilated and 36 ventilated patients while monitoring central venous pressure. The IJV and IVC were measured during the respiratory cycle and the IJVarea and IVCindex were calculated.
