Preformed Laryngeal Mask Double Lumen

Preformed laryngeal mask double lumen holding skills
The holding skills of preformed laryngeal mask double lumen are a basic and critical skill in airway management. The correct holding method can not only ensure the smooth insertion of the laryngeal mask, reduce the pain and injury of the patient, but also improve the efficiency of airway management and reduce the risk of complications. Therefore, medical staff should fully understand and master the skills of holding the laryngeal mask before operation.
Holding method of preformed double lumen laryngeal mask
Preparation
Check the laryngeal mask: Before operation, the integrity, airtightness and cuff of the laryngeal mask should be carefully checked.
Lubricate the laryngeal mask: Use an appropriate amount of lubricant to lubricate the cuff and the back of the ventilation mask of the laryngeal mask to reduce friction resistance during insertion.
Adjust the patient's position: The patient should be in a supine position with the head slightly tilted back to better expose the glottic area.
Holding posture
Holding position: The operator should hold the laryngeal mask in a pen-like manner with the dominant hand (usually the right hand). Specifically, the fingers should be bent naturally, and the thumb and index finger should be used to hold the ventilation mask part of the laryngeal mask, while the middle finger, ring finger and little finger should be used to hold the handle or cuff part of the laryngeal mask.
Gripping strength: When holding the laryngeal mask, the appropriate strength should be maintained, neither too tight nor too loose. Too tight may cause finger fatigue and affect the flexibility of operation; too loose may cause the laryngeal mask to slip or shift during insertion.
Adjustment before insertion
Adjust the angle of the laryngeal mask: After holding the laryngeal mask, the angle of the laryngeal mask should be adjusted appropriately according to the patient's oral and throat structure to better adapt to the patient's anatomical characteristics.
Check the cuff pressure: Before insertion, check whether the cuff pressure is moderate. Generally, the cuff pressure should be kept within a certain range (such as below 60cmH2O) to ensure that it can provide sufficient sealing effect without causing excessive pressure on the patient.

Insertion process
Insertion direction: Direct the opening direction of the laryngeal mask toward the patient's mandible, and insert the front end of the laryngeal mask into the inside of the patient's mouth close to the patient's maxilla.
Push along the anatomical structure: During the insertion process, the laryngeal mask should be pushed along the patient's oral and pharyngeal anatomical structure. At the same time, the operator should maintain the flexibility of the fingers so that the position and angle of the laryngeal mask can be adjusted in time when encountering resistance.
Observe the ventilation effect: After the laryngeal mask reaches the expected position, manual ventilation should be given immediately to observe the ventilation effect. If the ventilation is smooth and the chest rises and falls significantly, it means that the laryngeal mask is in the correct position; if the ventilation is not smooth or the chest does not rise and fall, the position of the laryngeal mask should be adjusted immediately or reinserted.
Precautions
Avoid violent operation: When inserting the laryngeal mask, avoid using violence or excessive force to avoid damaging the patient's surrounding tissues such as the mouth, throat or esophagus.
Keep the airway open: After inserting the laryngeal mask, ensure that the patient's airway remains open to avoid serious complications such as suffocation or aspiration.
Monitor vital signs: After inserting the laryngeal mask, the patient's blood pressure, heart rate and other vital signs should be closely monitored to detect and deal with abnormal conditions in a timely manner.
