How to choose and use anesthesia mask correctly

Anesthesia masks are common medical equipment consumables in operating rooms and an indispensable part of non-invasive ventilation. Below I will describe the reasons for using anesthesia masks and the correct selection of anesthesia masks.

Reasons for using anesthesia mask

When general anesthesia is applied to the patient, an anesthesia mask is needed. In the initial stage of general anesthesia, the anesthesia mask is connected to the anesthesia circuit to deliver oxygen and volatile anesthetic gases (such as sevoflurane, enflurane, isoflurane, etc.) to the patient. When the patient inhales enough anesthetic gas, enter it In the "sleeping" state during the maintenance period of anesthesia, the mask will be removed, and the anesthesiologist will intubate the patient's trachea or insert a laryngeal mask to establish an artificial airway. In the final stage of the operation, the anesthesia mask will be used again to provide the patient with oxygen and help the patient recover from anesthesia. In some cases, the anesthesiologist will maintain the mask in a fixed position throughout the operation (if the operation time is short), or use a hook and loop to fix the anesthesia mask during a longer operation.

How to choose an anesthesia mask

In any anesthesia process, choosing a suitable anesthesia mask needs to consider many factors. Some hospitals stipulate that the doctor in the hospital must choose a disposable anesthesia mask to eliminate cross-infection between patients. Most doctors are most concerned about the choice of anesthesia mask for its sealing performance. However, despite the great efforts of foreign companies with advanced technology, it is still difficult to produce an anesthesia mask that can provide 100% sealing for each patient. . Therefore, the practice of anesthesia mask selection is mainly the work of clinicians. Some doctors like an anesthesia mask with an inflatable cushion, believing that it can bring enough sealing pressure to fit the face tightly. In addition, some doctors like an anesthesia mask without an inflatable cushion, believing that its edge design conforms to the human facial anatomy , It brings better sealing performance than a bladder mask, and at the same time it brings a more comfortable experience when wearing the patient, especially for those patients who have undergone facial surgery or have a history of cosmetic surgery, doctors often do not need to use a larger The force buckles the mask to form a seal. The soft edge and anti-slip ring of the non-capsular anesthesia mask, and the design that conforms to the anatomical structure, bring a more comfortable experience to the patient and reduce the psychological burden on the patient and doctor.
