Laryngeal mask anesthesia is a technique of general anesthesia with a laryngeal mask placed for the purpose of breathing control during surgery.

Cerebral aneurysm is a common disease in neurosurgery, especially ruptured cerebral aneurysm is an emergency condition, requiring early intervention to reduce the complication rate for patients. The percentage of aneurysms in the anterior circulation is the majority, surgery to clamp the brain aneurysm in case of rupture needs to be performed urgently.
Current treatment methods for brain aneurysms include:
Medical treatment (non-surgical); Surgical treatment or clamping of the aneurysm; Endovascular therapy or coil placement.

Microsurgery clamping aneurysm is a classic and widely used treatment method in the treatment of cerebral aneurysms and an important supportive method to accurately assess the surrounding structures, help place the clip. accurate and safe.
Supportive endoscopic surgery can be applied in patients with aneurysms of the anterior cerebral vascular system, posterior cerebral artery system.
Aneurysm of the internal carotid artery. Posterior communicating aneurysms Anterior communicating aneurysms Aneurysms of the basilar artery Aneurysms AICA, PICA Aneurysms of the middle cerebral artery. Most types of brain aneurysms can be endoscopically assisted with microsurgery.
There is no absolute contraindication to the use of aneurysm clamp-assisted laparoscopy. In some cases of surgery to clamp aneurysms, it is difficult to use endoscopic support because there is no space for instruments and endoscopes.

The laryngeal mask is a means of opening the upper airway, consisting of a large barrel and an elliptical balloon at the lower end. Once placed and inflated, the balloon is closed with low pressure around the larynx entrance. Due to its convenience and nature, airway control is easier than with an endotracheal tube. Therefore, the laryngeal mask has been officially included in the difficult airway management regimen, especially in the situation where ventilation is not possible, intubation is not possible.
Laryngeal mask anesthesia is a technique of general anesthesia with a laryngeal mask placed for the purpose of breathing control during surgery.
This method of anesthesia is indicated in the following cases:
When intubation is difficult, especially difficult to ventilate or cannot be ventilated. Airway and respiratory control in general anesthesia for certain surgeries Temporary airway and respiratory control in the emergency department. Contraindicated in case:
Stomach full. Maxillofacial trauma complicated by trauma or infection Insufficient means of anesthesia and resuscitation.

Position: Lie on your back, breathe 100% oxygen 3-6 l/min at least 5 minutes before induction of anesthesia. Install a Monitor Set up an effective transmission line. Pre-anesthesia (if necessary) Initiate anesthesia Perform laryngeal mask placement technique Maintain anesthesia.

Reflux of gastric juice into airways Hemodynamic disturbances: Hypotension or elevation of blood pressure, cardiac arrhythmias (bradycardia, tachycardia, arrhythmias) Failure to place laryngeal mask, laryngotracheal-bronchospasm. Respiratory symptoms: Folding, slipping of the laryngeal mask, or opening of the respiratory system, the oxygen source is exhausted, the soda is ineffective, leading to hypoxia and hyperemia. Complications after removing the laryngeal mask such as: Respiratory failure due to many causes, sore throat hoarseness, spasms of the larynx - gas - bronchi, inflammation of the upper respiratory tract.
