Along with the development of science and technology, laparoscopic partial splenectomy is showing more advantages than open surgery. For successful surgery, it is impossible not to mention the role of anesthesia.

1. The position and role of the spleen in the body

The spleen is a small organ located on the left side of the abdomen, below the rib cage. The spleen has the following important functions:
The spleen is involved in the production of lymphocytes - an important part of the immune system in the body. During the fetal stage, the spleen also produces red blood cells, platelets, and granulocytes. The spleen is also the site of destruction of aging blood cells, retaining iron, proteins and substances needed to create new cells. The spleen is also a place to store blood in the body: through the expansion of the spleen, it participates in the regulation of blood volume as well as the number of blood cells in the circulatory system. The spleen also plays a role in fighting infections for the body by filtering out bacteria and foreign objects in the blood.

2. Spleen injury

The spleen is the most easily injured solid organ in the body, the diagnosis of spleen injury is easy when the patient has typical symptoms such as:
Location of injury in the spleen area. There are signs of blood loss syndrome. There are symptoms of peritoneal irritation. When a patient's symptoms are unclear, but a splenic injury is suspected, the physician may perform exploratory measures such as:
Probing. Poke wash. Emergency laparoscopy. X-ray . Supersonic . CT-scanner. It is found that when removing the spleen will weaken the patient's immune system, infections can become more dangerous. At that time, the patient will have to be vaccinated every year and use prophylactic antibiotics. This is completely not beneficial for the body, so in cases where the spleen is not damaged much, splenectomy will be used. part sale. Intravenous anesthesia plays an important role in a surgery, in laparoscopic partial splenectomy in trauma, doctors often use endotracheal anesthesia.

3. Endotracheal anesthesia laparoscopic partial splenectomy in trauma

Endotracheal anesthesia is a technique of general anesthesia through endotracheal tubes for the purpose of controlling breathing during surgery and resuscitation after surgery for patients. This method requires medical facilities to have all the necessary modern equipment, and the operator must be trained and proficient in techniques.
3.1. Steps to perform endotracheal anesthesia laparoscopic partial splenectomy in trauma Check the record Check the patient Check the patient Perform the technique The general steps are: Patient position: supine, oxygen 100% at a rate of 3-6 l/min at least 5 minutes before induction of anesthesia. Install the tracker. Set up transmission. If necessary, pre-anesthesia can be performed. Induction of anesthesia: Sleeping pills. Analgesic . Muscle relaxants The condition for intubation is that the patient must sleep deeply and have enough muscle relaxation. Carrying out oral intubation: insert the endotracheal tube through the mouth, put the cannula in the mouth to prevent the patient from biting the tube (if necessary). Maintain anesthesia with intravenous or volatile anesthetics, analgesics, and muscle relaxants (if needed). Control the patient's breathing with a machine. Criteria for extubation: The patient is awake, following the doctor's orders. Patient can raise head for more than 5 seconds, TOF >0.9. The patient is breathing on his own, the respiratory rate is within normal limits. Pulse and blood pressure are stable. Temperature > 35 degrees C. The patient had no complications of anesthesia and surgery. 3.2. Complications and management in endotracheal anesthesia laparoscopic partial splenectomy in trauma 3.2.1. Reflux of gastric juice into the airways Gastrointestinal fluid is found in the oral cavity and airways. At that time, it is necessary to immediately aspirate the fluid, place the patient in a low position, and tilt the head to one side. Place the endotracheal tube quickly and clear the airways immediately. Then it is necessary to monitor for lung infections. 3.2.2. Hemodynamic disorders Patients with hypotension or hypertension, cardiac arrhythmias (tachycardia, bradycardia or arrhythmia). Treatment depends on the specific symptoms and cause.

3.2.3. Incident due to intubation Unable to intubate: manage with difficult intubation procedure or switch to another anesthetic method. Wrong placement of endotracheal tube into the stomach: Auscultation of the lungs without alveolar murmur, EtCO2 cannot be measured. Reinsert the endotracheal tube. Vocal - tracheobronchial spasm: Difficult or impossible to ventilate, auscultation with rales or no hearing at all. It is necessary to provide adequate oxygen to the patient, use more hypnotics and muscle relaxants, ensure ventilation, and use bronchodilators and corticosteroids. If breathing cannot be controlled, a difficult endotracheal intubation procedure should be used. Trauma during endotracheal intubation: patients have bleeding, broken teeth or damaged vocal cords, foreign objects fall into the airways,... Depending on the injury, appropriate treatment is available. 3.2.4. Respiratory complications Possible folding or retraction of the endotracheal tube deep into one lung, collapse or opening of the respiratory system, lack of oxygen. Management: immediately ensure ventilation and provide 100% oxygen, find and resolve the cause. 3.2.5. Complications after extubation Patients may experience respiratory failure after extubation. The patient may have a sore throat and hoarseness. Patient has laryngospasm - gas - bronchi. The patient may have an upper respiratory tract infection. The patient may have laryngotracheal stenosis. Depending on the symptoms and cause, the doctor will have an appropriate treatment.
