Equipment includes suction, appropriate-sized bag and mask, oxygen source, appropriate size endotracheal tubes including a size larger and one size smaller, laryngoscope and appropriate-sized laryngoscope blades (including one size smaller and one size larger), endotracheal tube-securing equipment (tape or other), ...

What is a laryngoscope blade used for?

Laryngoscope blades are used as the primary tool for examination of the interior of the larynx and for placement of an endotracheal tube.

Can you intubate without laryngoscope?

Digital intubation allows intubation to be performed without a laryngoscope or a view of the larynx and may be performed with or without a bougie [2].

Why is a laryngoscope blade used when placing an endotracheal tube?

Use of fiberoptics and a curved blade enable visualization of the larynx “around the corner” of the blade, thus eliminating the need to align the oral, pharyngeal, and tracheal axes. A standard laryngoscope handle or a flexible fiberoptic cable connected to a light source powers the fiberoptic light source.

What are the side effects of intubation?

Potential side effects and complications of intubation include:

  • damage to the vocal cords.
  • bleeding.
  • infection.
  • tearing or puncturing of tissue in the chest cavity that can lead to lung collapse.
  • injury to throat or trachea.
  • damage to dental work or injury to teeth.

Are you awake when intubated?

The two arms of awake intubation are local anesthesia and systemic sedation. The more cooperative your patient, the more you can rely on local; perfectly cooperative patients can be intubated awake without any sedation at all. More commonly in the ED, patients will require sedation.

Is being intubated the same as being on a ventilator?

Intubation is the process of inserting a breathing tube through the mouth and into the airway. A ventilator—also known as a respirator or breathing machine—is a medical device that provides oxygen through the breathing tube.

How far down does intubation tube go?

Most of the anaesthesia textbooks recommend depth of placement of ET to be 21 cm and 23 cm in adult females and males, respectively, from central incisors. [5,6] It is suggested that the tip of ET should be at least 4 cm from the carina, or the proximal part of the cuff should be 1.5 to 2.5 cm from the vocal cords.

Is intubation serious?

It's rare for intubation to cause problems, but it can happen. The scope can damage your teeth or cut the inside of your mouth. The tube may hurt your throat and voice box, so you could have a sore throat or find it hard to talk and breathe for a time. The procedure may hurt your lungs or cause one of them to collapse.

Can you talk while intubated?

An endotracheal (ET) tube helps the patient breathe. The tube is placed into the mouth or nose, and then into the trachea (wind pipe). The process of placing an ET tube is called intubating a patient. The ET tube passes through the vocal cords, so the patient won't be able to talk until the tube is removed.

How often is intubation wrong?

The incidence of failed intubation is ≈1 in 1–2000 in the elective setting,9,10 ≈1 in 300 during rapid sequence induction (RSI) in the obstetric setting,11 and ≈1 in 50–100 in the emergency department12 (ED), intensive care unit (ICU),13 and pre-hospital setting.

Why do doctors do tracheostomy?

A tracheostomy is usually done for one of three reasons: to bypass an obstructed upper airway; to clean and remove secretions from the airway; to more easily, and usually more safely, deliver oxygen to the lungs.

What is the life expectancy of a person with a tracheostomy?

The median survival after tracheostomy was 21 months (range, 0-155 months). The survival rate was 65% by 1 year and 45% by 2 years after tracheostomy. Survival was significantly shorter in patients older than 60 years at tracheostomy, with a hazard ratio of dying of 2.1 (95% confidence interval, 1.1-3.9).

Is a tracheostomy considered life support?

For people with a tracheostomy — a breathing tube in their throat — the mucus gets trapped in their lungs. It has to be suctioned several times throughout the day. The procedure is life-saving.

When is a laryngoscope used?

Doctors sometimes use a small device to look into your throat and larynx, or voice box. This procedure is called laryngoscopy. They may do this to figure out why you have a cough or sore throat, to find and remove something that's stuck in there, or to take samples of your tissue to look at later.
