Abstract The passage of a tube into the trachea, whether through the nose or the mouth, is known as intubation, and probably presents more hazards than any other single anaesthetic procedure. [link.springer.com]
Entire Body System
- Unconsciousness
In emergency situations, the patient is often unconscious at the time of this procedure. What kind of tube is used? The tube that is used today is usually a flexible plastic tube. [medicinenet.com]
An endotracheal tube may be used to maintain a patent airway, to prevent aspiration of material from the digestive tract in the unconscious or paralyzed patient, to permit suctioning of tracheobronchial secretions, or to administer positive-pressure ventilation [medical-dictionary.thefreedictionary.com]
Whether you are awake (conscious) or not awake (unconscious), you will be given medicine to make it easier to insert the tube. After endotracheal intubation, you will likely be placed on a breathing machine. [ufhealth.org]
Whether you are awake (conscious) or not awake (unconscious), you will be given medicine to make it easier and more comfortable to insert the tube. You may also get medicine to relax. [medlineplus.gov]
- Hypoxemia
KEYWORDS: endotracheal intubation; hypoxemia; randomized trial [ncbi.nlm.nih.gov]
Up to 40% of cases are associated with marked hypoxemia or hypotension. [ccforum.biomedcentral.com]
First, among the patients in the two groups, there was a high rate of severe hypoxemia (SpO 2 < 90%) prior to airway management (14% in the AO group vs. 17% in the control group) [ 10 ]. [omicsonline.org]
PHYSIOLOGIC RESPONSES TO INTUBATION The process of intubation may cause hypoxemia, 17 bradycardia, 18 intracranial hypertension, 19 systemic hypertension, 17 and pulmonary hypertension. 20 Hypoxemia seems to be related either to apnea at the time of intubation [pediatrics.aappublications.org]
This rare syndrome consists of muscular rigidity, extreme hyperpyrexia, hypoxemia, hypercarbia, rhabdomyolysis, autonomic instability, metabolic acidosis, and disseminated intravascular coagulation (DIC). [emedicine.medscape.com]
- Swelling
As the pseudomembrane gets larger, swelling worsens and lymph nodes become enlarged, giving the neck a “bull-neck” appearance. [brainblogger.com]
Her tongue is protruding from her mouth with marked swelling to the tongue and lips. The patient is protective of her position and cannot tolerate lying back or being supine. [emdocs.net]
In these cases, visualization of the laryngeal inlet during laryngoscopy may be impossible, and local trauma caused by the laryngoscope blade or attempts at ETT insertion can lead to increased swelling, rendering mask ventilation difficult or impossible [uptodate.com]
The most common cause for postoperative hoarseness in patients undergoing procedures that do not involve the head and neck is swelling of the vocal cords. [anesthesiology.pubs.asahq.org]
These signs and symptoms include but are not limited to sore throat, pain or swelling of the face and neck, chest pain, subcutaneous emphysema, and difficulty swallowing. [surgeryencyclopedia.com]
- Falling
None of the patients had any adverse effects such as hypotension, bradycardia, respiratory depression and fall in oxygen saturation. [ijaweb.org]
With severe anemia, cyanosis may not be apparent until the arterial oxygen saturation (Sao 2 ) falls to 60%. [clinicalgate.com]
Before intubation, gas anesthesia pipes were prone to leak, and surgeons, leaning close to anesthetic gas for hours at a time, would often fall asleep on top of their patients. [brainblogger.com]
Although attractive, mivacurium falls short in matching succinylcholine in its simplicity, ultrashort onset, and short duration of action. Pancuronium Pancuronium is an aminosteroid NMB. [emedicine.medscape.com]
- Inflammation
Once in the lungs the meconium can make the baby ill by obstructing the airways and causing inflammation this is called meconium aspiration syndrome. [cochrane.org]
Classification of intubation injuries: Acute intubation changes: General, Non specific: Inflammation, edema, protrusion of ventricular mucosa Pressure necrosis, loss of mucosa, cartilage and muscle Glottic: Flaps of granulation tissue Granulation tissue [drtbalu.co.in]

Respiratoric
- Aspiration
Once in the lungs the meconium can make the baby ill by obstructing the airways and causing inflammation this is called meconium aspiration syndrome. [cochrane.org]
In addition, this method is frequently used for aspiration of secretions in patients with atelectasis, pulmonary edema or excess secretions associated with other pulmonary conditions. [nejm.org]
Cricoid pressure (debatable) Aspiration of stomach contents by NG tube Fasting the patient in preparation Careful bag-mask ventilation to prevent gastric inflation Alternatively: do not bag-mask ventilate (RSI) Pneumothorax and tension pneumothorax Use [derangedphysiology.com]
- Pneumonia
Intensive care units employ infection control and reduction schemes to reduce pneumonia rates. [ncbi.nlm.nih.gov]
Support breathing in certain illnesses, such as pneumonia, emphysema, heart failure, collapsed lung or severe trauma. Remove blockages from the airway. Allow the provider to get a better view of the upper airway. [ufhealth.org]
Aspiration of stomach contents can result in pneumonia and ARDS. Placement of the tube too deep can result in only one lung being ventilated and can result in a pneumothorax as well as inadequate ventilation. [medicinenet.com]
Mg Hypoxia from de-recruitment of lungs conversion from spontaneous ventilation -> positive pressure ventilation results in de-recruitment when patient apnoeic preoxygenation quick securement of airway increasing PEEP on ventilator Sputum retention + pneumonia [lifeinthefastlane.com]
- Hoarseness
Previous research by Jones et al. found that 54 of 167 studied patients had hoarseness following short-term intubation. 7 In five of these patients, hoarseness lasted for periods ranging between 9 and 99 days. [anesthesiology.pubs.asahq.org]
Cases of postoperative hoarseness, vomiting, dysphoria, bucking, and other complications were determined in the two groups. [alliedacademies.org]
Grade of hoarseness [19]: rating of 0, no hoarseness; level 1, mild hoarseness (complained of hoarseness only when asked); level 2, moderate hoarseness (self-reported hoarseness); level 3, severe hoarseness (change in voice was observed). [bmcanesthesiol.biomedcentral.com]

Aspirating (inhaling) vomit, saliva or other fluids while intubated Pneumonia, if aspiration occurs Sore throat Hoarseness Erosion of soft tissue (with prolonged intubation) The medical team will assess and be aware of these potential risks, and do what [verywell.com]
- Dyspnea
The trachea is suctioned every hour and as needed, as indicated by patient assessment (dyspnea, gurgling, respirations, activation of ventilator pressure alarms). If so ordered, the trachea is irrigated with normal saline solution. [medical-dictionary.thefreedictionary.com]
- Abnormal Breathing
Because of the intrathoracic location of a large distensible viscus, bilateral breath sounds may be heard during manual ventilation. 12 For these reasons, whenever abnormal breath sounds are heard, they should not be relied on to confirm endotracheal [clinicalgate.com]
Gastrointestinal
- Vomiting
Cases of postoperative hoarseness, vomiting, dysphoria, bucking, and other complications were determined in the two groups. [alliedacademies.org]
Suction: In most resuscitation situations, the patient will either vomit, or at the very least, will have an excess of secretions in their oropharynx. If available, a suction catheter should be included as part of your basic airway equipment. [meds.queensu.ca]

Skin
- Ulcer
[…] of vocal process Ulcerated troughs and intact median strip Posterior ulceration without intact median strip Subglottis: Bilateral posterolateral midcricoid ulceration Annular inferior cricoid ulceration Chronic long term complications: General: Submucosal [drtbalu.co.in]
Adverse events included 3 interface-related skin ulcers for each group (ie, 7.6% in the face mask group had nose ulcers and 6.8% in the helmet group had neck ulcers). [jamanetwork.com]
While the length of intensive care unit stay was significantly reduced with the helmet interface, there were no significant differences in the length of hospitalization or in the rate of skin ulcerations. [dynamed.com]
Mercury, for example, was administered in the form of a vapor, and was used as a treatment for membranous croup and ulcers of the mouth and throat, as well as for diphtheria. Sometimes, good things come from bad, as in the case of diphtheria. [brainblogger.com]

Adverse events included 3 interface-related skin ulcers for each group (ie, 7.6% in the face mask group had nose ulcers and 6.8% in the helmet group had neck ulcers). [jamanetwork.com]
Neurologic
- Confusion
The lack of a single, reliable test to confirm ETT placement can potentially lead to confusion regarding the location of the tube. [aliem.com]
These complications are rare but may include: heart attack lung infection stroke temporary mental confusion death Approximately one or two people in every 1,000 may become partially awake while under general anesthesia. [healthline.com]
This condition should not be confused with that of prolapse of ventricle which is a distinct entity. 3. Subglottic oedema. This condition usually resolves after extubation. Granulation tissue: Can be seen within 48 hours after intubation. [drtbalu.co.in]
There are obvious exceptions to performing awake intubation, such as patient refusal, young children, and uncooperative patients (due to confusion or learning disabilities). [nysora.com]
Workup
Serum
- Hypercapnia
Endotracheal intubation may be achieved by awake direct laryngoscopy in the sick ICU patient whose level of consciousness may be reduced by sepsis, hypercapnia or hypoxemia. [ccforum.biomedcentral.com]
Indications for endotracheal tube (ETT) placement include: severe hypoxaemia requiring PEEP; hypercapnia with acidosis; inability to protect the airway; to control ventilation in the presence of raised intracranial (or intraocular) pressure; to facilitate [en.wikibooks.org]
Airway obstruction is common at the accident scene in patients with severe TBI [ 10, 11 ], and resulting hypoxaemia and hypercapnia are known to trigger secondary injuries that adversely affect outcome [ 12, 13 ]. [journals.plos.org]
Treatment
This is a surgical emergency and prompt recognition and initiation of treatment is essential to a favorable outcome. There are very few case reports of medical treatment [4]. Medical treatment has been applied only after early diagnosis. [ejcts.oxfordjournals.org]
Some of these opinions may contain information about treatment or uses of drug products that have not been approved by the U.S. Food and Drug Administration. WebMD does not endorse any specific product, service, or treatment. [webmd.com]
Nevertheless, successful conservative treatment in a large tracheal tear has been reported. 11, 12 Mullan et al have suggested that the length of intact trachea > 3 cm above the carina is the important predictor of successful conservative treatment. 12 [rc.rcjournal.com]
In addition, urolithiasis was also associated with a high risk of intensive care unit treatment, shock, and arrhythmias after AMI. Medical treatments for urolithiasis may decrease the risk of MI, except the use of NSAIDs. [dovepress.com]
Prognosis
Knowledge of associated clinical variables may improve the estimation of early prognosis and guide management in these patients. [neurology.org]
Outlook (Prognosis) The outlook will depend on the reason the procedure needed to be done. References Driver BE, Reardon RF. Tracheal intubation. In: Roberts JR, Custalow CB, Thomsen TW, eds. [mountsinai.org]
After discussion with the patient's relatives about the risk of surgical repair and the prognosis of neurological condition, conservative treatment was considered. [rc.rcjournal.com]
However misreading of this complication sometimes leads to delaying the diagnosis, then to worsening the prognosis. Subsequent infection spreads into the mediastinum and responsibility of the physician is engaged. [ejcts.oxfordjournals.org]
This result shows why it is vital to analyze data by the intention-to-treat principle; in this case, an erroneous conclusion could be reached if the data were analyzed by treatment received, because the success of intubation is not independent of prognosis [jamanetwork.com]
