Low-flow Anaesthesia for Lung Protection

As Your Specialist in Acute Care we understand how perioperative lung protective ventilation during general anaesthesia can reduce the incidence of postoperative pulmonary complications (PPC). PPC are common complications after general anaesthesia.

Read on and find out how low-flow anaesthesia can positively influence complication rates.

Why is low-flow anaesthesia better for pulmonary function than the high-flow technique?

The upper respiratory tract plays an important role in acclimatising the inhaled gas as the respiratory epithelium of the lower respiratory tract changes towards the terminal bronchioles, successively decreasing the capability to humidify and warm the inspired gas. During anaesthesia, however, the upper respiratory tract is bypassed by endotracheal intubation or a laryngeal mask, leaving the lower respiratory tract potentially overcharged with the task of adequately acclimatising the cold and dry gas applied during high flow anaesthesia. Mechanical ventilation with cold and dry gas can thus lead to damage of the lung parenchyma.

Various studies demonstrated that protective ventilation approaches allow the reduction in incidence of postoperative pulmonary complications (PPC).

Clinical techniques for use with rebreathing systems

Wide-ranging clinical experience shows that low-flow anaesthesia is a safe and simple-to-perform technique and can be easily used in daily clinical routine. ”The safety and technical capability of today’s anaesthesia machines make low-flow, minimal-flow and metabolic-flow anaesthesia the procedures of choice.” This is the conclusion of Bert Mierke (MD/PhD) and Christian Hoenemann (MD/PhD), passionate low-flow advocates and authors of the booklet on low- , minimal- and metabolic flow anaesthesia.

This booklet provides background information and practical advice for the safe use of these techniques.

How can you reduce costs in the OR?

The use of low-flow anaesthesia reduces consumption of volatile anaesthetic agents as well as nitrous oxide and oxygen. Apart from significant cost savings, the negative ecological effects of volatile anaesthetic agents can be reduced.

Learn how hospitals substantially reduced their agent consumption by using low-flow anaesthesia in these reference cases.

Dräger anaesthesia machines feature a platform that allows the anaesthesia team to adjust the flow rate of the anesthetic, and has provided us with a savings of over $100,000 in pharmaceutical costs in the first year.

Although low- and minimal-flow anaesthesia offers many benefits, successful adoption has been hindered by a lack of simple-to-use methods to guide anaesthetists on the efficient usage of volatile gases. This is now set to change following an advancement in gas monitoring software, which measures the actual agent consumption versus uptake.
