Trachea - Wikipedia
The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the pharynx The epiglottis closes the opening to the larynx during swallowing. A tracheotomy is often performed for ventilation in surgical operations where needed. 4 Bioengineering and prosthesis; 5 Additional images; 6 External links. The trachea is part of the conducting airway system that begins consists of a blind-ending esophagus with no tracheal connection and and the surgeon should be entering the trachea with a scalpel and no electrocautery. Epiglottitis is characterized by inflammation and swelling of your . During this procedure, your doctor inserts a needle into your trachea.
Just below the thyroid, the membrane covering the trachea is divided Band the trachea itself is cut C. A cross incision is made to enlarge the opening Dand a tracheostomy tube may be put in place E. Aftercare Postoperative care A chest x ray is often taken, especially in children, to check whether the tube has become displaced or if complications have occurred.
The doctor may prescribe antibiotics to reduce the risk of infection.
If the patient can breathe without a ventilator, the room is humidified; otherwise, if the tracheotomy tube is to remain in place, the air entering the tube from a ventilator is humidified. During the hospital stay, the patient and his or her family members will learn how to care for the tracheotomy tube, including suctioning and clearing it. Secretions are removed by passing a smaller tube catheter into the tracheotomy tube. It takes most patients several days to adjust to breathing through the tracheotomy tube.
At first, it will be hard even to make sounds. If the tube allows some air to escape and pass over the vocal cords, then the patient may be able to speak by holding a finger over the tube. Special tracheostomy tubes are also available that facilitate speech. The tube will be removed if the tracheotomy is temporary.
Then the wound will heal quickly and only a small scar may remain. If the tracheotomy is permanent, the hole stays open and, if it is no longer needed, it will be surgically closed. Warm compresses can be used to relieve pain at the incision site. The patient is advised to keep the area dry.

It is recommended that the patient wear a loose scarf over the opening when going outside. He or she should also avoid contact with water, food particles, and powdery substances that could enter the opening and cause serious breathing problems. The doctor may prescribe pain medication and antibiotics to minimize the risk of infections. If the tube is to be kept in place permanently, the patient can be referred to a speech therapist in order to learn to speak with the tube in place.
The tracheotomy tube may be replaced four to 10 days after surgery. Patients are encouraged to go about most of their normal activities once they leave the hospital. Vigorous activity is restricted for about six weeks.
Endoscopic treatment is possible in selected patients, but open reconstruction is superior in more severe cases. Foreign body aspiration needs to be managed according to a clear algorhythm. Recurrent respiratory papillomatosis should be treated with emphasis on function preservation. The role of adjuvant medication remains unclear.
Infectious diseases can be managed conservatively by a pediatrician in the majority of cases. The inspiratory stridor is the leading symptom for all laryngotracheal stenoses.
Certainly not all respiratory sounds allow you to define neither the type, nor the location of the stenosis. Nor do they give a correlation to the degree of the stenosis. Oftentimes it is the patient history that leads to the most possible etiology.
Most of the acquired stenoses of the upper airway had been caused iatrogenically. The improvements of perinatal intensive care have lead to significantly higher survival rates of extremely premature children.
Epiglottitis: Causes, Symptoms, and Diagnosis
In most of these cases this leads to intubation and long-term intensive care medicine. Even though the relative risk of an intubation-associated stenosis is certainly low today, we continue to deal with a considerably higher number of surviving premature children after long-term intubation through intensive care medicine. This means that the total number of airway stenosis probably is not declining.
Endoscopy can never be overrated for differential diagnosis of the laryngotracheal stenosis. Only through the endoscopy is it possible to detect the exact location, the degree and the topographic relation of the stenosis to anatomic landmarks.
However, the activity and the consistence of the stenosis as well as the mobility of the arytenoid cartilage and the condition of the surrounding tissue are extremely important parameters. Rigid telescopes give the most reliable information even though the usage demands an extremely supervised condition of the sedated child with or without spontaneous breathing.
This technique requires a certain effort because the presence of an anaesthesiologist is needed, which allows and improves the security in the event of unexpected incidents. In contrast flexible fibre-optic endoscopy often provides only little informative value.
The worse quality of the picture, the changing points of view and the shorter available time for examination do not allow for a detailed analysis. The outcome is a blind-ending esophagus and a blind starting esophagus.

Neither have any tracheal connection. Type B entails of the upper esophagus forming a fistula with the trachea and a blind starting esophagus without any tracheal connection. If the bronchial component is present, the fistula will most likely form from the right bronchus. In Type D, the upper and lower esophagus is not connected; however, both the upper and lower portions have a fistula connecting to the trachea. Type E also known as H-type due to forming the letter H consists of a failure of the mid portion of the esophagus to separate from the trachea.
Tracheal Stenosis Tracheal stenosis is a narrowing of the airway that could potentially lead to complete obstruction and therefore the cessation of ventilation. This condition can be congenital or develop later in life due to adjacent structures compressing the trachea, accumulation of granulation tissue, or edema from trauma, infection, or hemorrhage. If the weakness extends into the bronchi, it is termed tracheobronchomalacia.
Diagnoses would be most likely made through ultrasound at prenatal visits. Surgical Considerations As with all surgical procedures involving the airway, surgeons must always exercise caution.
The surgeon should always be ready to perform an emergency airway if it becomes compromised. Tracheostomy is the creating of an opening connecting the anterior neck to the trachea to bypass the oral pharynx, pharynx, and larynx. This may be performed under local anesthetic or general anesthesia.
Caution must be used during the procedure to prevent an airway fire. Anterior mediastinal mass provides multiple changes to the anesthetic provider. One should assess how severe the mass is compressing the trachea through the use of imaging. If the patient cannot keep their airway patent while sleeping or lying flat, an awake fiber-optic intubation should be performed.
If the mass compresses the trachea distal to the endotracheal tube, initiation of bypass or extracorporeal membrane oxygenation must be readily available.
Tracheal rupture may be caused by infection, trauma, or ulcerations. A tracheal stent is one type of treatment that could be utilized depending on the severity. Placement of a tracheal stent with a rigid bronchoscope can give rise to some anesthetic difficulties to adequately ventilate and provide inhalational anesthetic to the patient. Jet ventilation may be utilized, and careful visualization of chest rise and retraction should be noted ensuring adequate ventilation.
One may also use total intravenous anesthetic because the use of inhalation anesthetic gases will be limited during the use of jet ventilation.
