When a tracheostomy is no longer needed, it can be removed and allowed to heal on its own, or the physician may close it surgically. Patients can be discharged home with a trach; but with that, comes new learning experiences. A trained respiratory therapist or a professional nurse will help you and your family learn to care for the trach.
Each breath is pushed into the endotracheal tube and into the lung. An endotracheal tube is also needed if a patient is unconscious or has a brain injury. The brain controls the reflex in the airway that prevents choking when we swallow or eat. This reflex is called the gag reflex. The top of the windpipe has a special opening called the epiglottis. When we swallow food, the epiglottis closes to prevent food from entering the windpipe. When patients are heavily sedated, unconscious or have a brain injury, this protective response is often impaired.
Without a gag reflex, saliva would enter the windpipe. This is called aspiration. Aspiration is a serious complication and one of the causes for pneumonia. A less common reason for intubating a patient is to keep the airway open. This is seen most commonly in patients with tumours or growths in the neck or upper chest. The usual route for inserting an endotracheal tube is through the mouth. However, advancement in endotracheal tube design and recognition of key principles mitigating complications e.
The optimal timing of tracheostomy among intubated patients is a point of ongoing debate, wherein a spectrum of distinct considerations, including impact on ventilator-associated pneumonia VAP , laryngotracheal injury, and mortality are assessed.
Establishing a discrete temporal threshold for tracheostomy is complicated by the existence of a heterogenous patient population with inherently distinct risks for intubation-related complications. Indications include surgeries in which general anesthesia is provided and in emergencies for respiratory failure. These indications differ significantly in airway management. Routine procedures are performed on stable patients with good physiologic reserve.
During breathing, air enters the nose and mouth and travels down the trachea and into the lungs. Oxygen is inhaled, which goes into the lungs and gets absorbed into the bloodstream.
Carbon dioxide is exhaled out the mouth and nose. The symptoms of respiratory failure will depend on the cause as well as the levels of oxygen and carbon dioxide in the blood. For patients with low oxygen levels in the blood, patients typically present with shortness of breath and air hunger.
Breathing can be affected due to conditions that weaken the muscles and nerves that support breathing. These conditions can include strokes, muscular dystrophy, amyotrophic lateral sclerosis ALS , and spinal cord injuries. Other conditions can affect the bones or tissues that support breathing, such as an injury to the chest. Scoliosis or other problems with the spine affect the bones and muscles used for breathing.
Other conditions can affect the lungs directly such as chronic obstructive pulmonary disease COPD , pneumonia, COVID, cystic fibrosis, pulmonary embolism, or adult respiratory distress syndrome.
Intubation can be life saving. However, there are risks that can arise from intubation, particularly if an individual is intubated for a prolonged period of time.
Some of these complications can be life-threatening. Minor complications of endotracheal intubation can includes sore throat, injury of the lips, gums, teeth or structures of the upper airway. Bleeding may also occur. More serious complications can include hypoxemia, hypotension, pulmonary aspiration, and difficulty in intubation, including oesophageal intubation. Clinicians working with intubated individuals and recently extubated individuals should be aware of the potential risks. The novel corona virus COVID pandemic has resulted in an increase in patients intubated and use of mechanical ventilation.
The United States and globally, we are likely to see an increase in tracheostomy as well, as patients may have difficulty weaning and require longer periods of time on a vent.
COVID also has implications for healthcare workers, as there are shortages with workers becoming ill from the virus.
