Effect of active airway warming with a heated-humidified breathing circuit on core body temperature in patients under general anesthesia: a systematic review and meta-analysis with trial sequential analysis [PDF]

Korean Journal of Anesthesiology, 2023
Background The application of a heated-humidified breathing circuit (HHBC) may reduce respiratory heat loss during mechanical ventilation, but its effect in preventing intraoperative hypothermia is controversial.

The effect of heated breathing circuit on body temperature and humidity of anesthetic gas in major burns [PDF]

Korean Journal of Anesthesiology, 2013
BackgroundCold and dry gas mixtures during general anesthesia cause the impairment of cilliary function and hypothermia. Hypothermia and pulmonary complications are critical for the patients with major burn.

Comparing the hemodynamic effect of a large arteriovenous fistula during high and low cardiac output states

Frontiers in Physiology, 2023
Background: A large arteriovenous fistula (AVF) is a low-resistant circuit that affects organ perfusion and systemic hemodynamics even in standard conditions. The extent of its’ effect in critical states has not been elucidated yet.

Translational design for limited resource settings as demonstrated by Vent-Lock, a 3D-printed ventilator multiplexer

3D Printing in Medicine, 2022
Background Mechanical ventilators are essential to patients who become critically ill with acute respiratory distress syndrome (ARDS), and shortages have been reported due to the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods

A large arteriovenous fistula steals a considerable part of systemic blood flow during veno-arterial extracorporeal circulation support in a porcine model

Frontiers in Physiology, 2023
Background: Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is one of the most frequently used mechanical circulatory support devices.

Desflurane consumption during automated closed-circuit delivery is higher than when a conventional anesthesia machine is used with a simple vaporizer-O₂-N₂O fresh gas flow sequence

BMC Anesthesiology, 2008
Background The Zeus® (Dräger, Lübeck, Germany), an automated closed-circuit anesthesia machine, uses high fresh gas flows (FGF) to wash-in the circuit and the lungs, and intermittently flushes the system to remove unwanted N2.

Minimal flow anesthesia can be initiated early with the use of higher fresh gas flow to facilitate desflurane “Wash-in”

Journal of Anaesthesiology Clinical Pharmacology, 2019
Background and Aims: More than 80% of delivered anesthetic gases get wasted at high fresh gas flows as they are vented out unused. Use of minimal flow anesthesia is associated with less waste anesthetic gas emission and environmental pollution.

OXYGEN DELIVERY, GASES AND ACID-BASE BALANCE OF ARTERIAL BLOOD DURING XENON ANESTHESIA OF THE CLOSED CIRCU

Вестник анестезиологии и реаниматологии, 2018
Xenon is an inert gas being very close to an ideal anesthetic. Goal of the study: to evaluate changes in gases and acid-base balance of arterial blood during general xenon anesthesia with the closed circuit and to compare it with general anesthesia with ...
