The Affecting Factors on Airway Temperature and Moisture
2019年12月18日 更新者：Ozkan Onal、Selcuk University
The Effects of Different Fresh Gas Flows and Different Anesthetics on Airway Temperature and Moisture in Patients Who Underwent General Anesthesia
There is no literature information about the flow rate of fresh gas mixture (air+O2) in the patients who underwent general anesthesia.
Different flow rates of fresh gas mixture are used in both the investigator's hospital and the experiences of the anesthesiologists.
It is aimed to study the effects of different fresh gas flow rates on the rate of temperature and moisture of the airway of patients who underwent general anesthesia.

条件
详细说明
Under physiological conditions, inhaled air is heated and humidified as it passes through the nose and upper airways until reaching the alveoli.
This mechanism is bypassed by endotracheal intubation.
Ventilation with dry and cold compressed gases leads to loss of water and heat from the respiratory tract.
Drying of the respiratory tract can lead to destruction of the cilia and mucous membranes, resulting in decreased mucociliary transport and increased concentration of secretions.There is no definitive literature on fresh gas mix (oxygen + air) flow rates in patients under general anesthesia.
This study aimed to investigate whether two fresh gas flow rates routinely employed in the authors' practice affected airway temperature and humidity.

3 lt/min
Patients in the study were divided into two main groups according to the standard fresh gas flow administered (3-6 L/min).
Each main group was then divided into subgroups as follows: sevoflurane + remifentanil, desflurane + remifentanil, or propofol + remifentanil (TIVA).
These six groups were further divided into two groups according to use or non-use of a heat and moisture exchanger (HME) filter.
