The process of tracheal intubation by conventional laryngoscopy entails the following: a view of the larynx is obtained by manipulat- ing the laryngoscope with the left hand, and then a tube is pushed into the trachea with the right hand. This is a stan- dard practice used in all medical institutions.
Why do we hold the laryngoscope in the left hand?
A left-hand laryngoscope can be used in these types of cases where anatomy and contour of the blade manoeuvres the tongue and the right-sided lesion, thereby providing an unobstructed left-sided view of the larynx.
How do you properly intubate?
The larger the tube, the less resistance to breathing there will be. Hold the preselected tube in your right hand like a pencil, curve forward. Pass the tube into the larynx through the cords in one smooth motion. If the patient is breathing, time the forward thrust for inspiration when the cords are fully open.
What is the best position for intubation?
Background: The sniffing position, a combination of flexion of the neck and extension of the head, is considered to be suitable for the performance of endotracheal intubation. To place a patient in this position, anesthesiologists usually put a pillow under a patient’s occiput.
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. Main Feature: The Miller Laryngoscope Blade . . . The most popular of the straight types.
Is a laryngoscope used for intubation?
The rigid laryngoscope is the device most commonly used for tracheal intubation. A direct line of vision is necessary for the successful insertion of a rigid laryngoscope.

What is McCoy laryngoscope?
McCoy laryngoscope is used in patients when difficulty in elevating epiglottis is encountered and activation of blade tip elevates the epiglottis and visualization of vocal cords.
Which hand do you hold your laryngoscope?
4-1) The laryngoscope is held in the intubator’s left hand and the right hand is used to open the mouth. The blade is advanced into the oropharynx in such a way as to sweep the tongue to the left side of the mouth and hold it there.
Which laryngoscope is most commonly used?
The most common laryngoscope blade used for intubation in adults is the curved Macintosh blade (Figure 34-4). This is inserted into the right side of the mouth to displace the tongue laterally. The tip of the blade sits in the vallecula and is lifted forward to elevate the epiglottis and expose the laryngeal inlet.
How do you know when to intubate?
Intubation is necessary when your airway is blocked or damaged or you can’t breathe spontaneously. Some common conditions that can lead to intubation include: Airway obstruction (something caught in the airway, blocking the flow of air). Cardiac arrest (sudden loss of heart function).
How hard is it to intubate?
Definition and incidence: “An intubation is called difficult if a normally trained anesthesiologist needs more than 3 attempts or more than 10 min for a successful endotracheal intubation.” The incidence of difficult intubation depends on the degree of difficulty encountered showing a range of 1-18% of all intubations …
When is the Trendelenburg position used?
Trendelenburg position is typically used for lower abdominal surgeries including colorectal, gynecological, and genitourinary procedures as well as central venous catheter placement.

Why would you put a patient in Trendelenburg position?
Trendelenburg position is widely used by nurses and other healthcare providers as a first-line intervention in the treatment of acute hypotension and/or shock. A review of the results of 5 research studies did not provide overwhelming support for its use as a treatment of hypotension.
What is Burp maneuver?
Applying backward, upward, rightward, and posterior pressure on the larynx (i.e., displacement of the larynx in the backward and upward directions with rightward pressure on the thyroid cartilage) is called the “BURP” maneuver and has been well described by Knill.
How should the cuff of a tracheal tube be passed?
Introduction. An optimal ETT placement should ensure sufficient distance (2–5 cm) between the tip of the ETT and the carina3 and sufficient distance (1.5–2.5 cm) between the proximal margin of the cuff to the vocal cords.
What size ET tube?
SIZES. The size of an ETT signifies the inner diameter of its lumen in millimeters. Available sizes range from 2.0 to 12.0 mm in 0.5 mm increments. For oral intubations, a 7.0-7.5 ETT is generally appropriate for an average woman and a 7.5-8.5 ETT for an average man.

Is video laryngoscopy direct or indirect?
Direct Laryngoscopy: Insertion of the endotracheal tube by a method of directly visualizing the vocal cords. Examples: Macinotosh blade, Miller Blade. Indirect Laryngoscopy: Insertion of the endotracheal tube by a method of indirectly visualizing the vocal cord, either using a video camera or optics (mirrors).
What is a Mac blade?
The Macintosh laryngoscope has a curved blade which allows exposure of the larynx by positioning the tip in the vallecula, anterior to the epiglottis, lifting it out of view. Macintosh originally designed the laryngoscope to facilitate intubation in unparalyzed patients.
What is a polio blade?
The blade is mounted at 135 degrees to the handle. This equipment was originally designed to facilitate intubation in patients encased within iron lung ventilators during the polio epidemic. It is also useful in patients with barrel chest, restricted neck mobility or breast hypertrophy.
Where does the Miller blade go?
The Miller blade is straight, and it is passed so that the tip lies beneath the laryngeal surface of the epiglottis (Fig. 14.4B). The epiglottis is then lifted to expose the vocal cords.
What is the size of laryngoscope blade for 30 weeks?
Using this rule, a 2.5mm ID endotracheal tube would be used for an infant born at 25 weeks’ gestation, a 3.0mm ID for an infant born at 30 weeks and a 3.5mm ID for an infant born at 35 weeks’ gestation.
When do babies grow out of Laryngomalacia?
If your child is born with laryngomalacia, symptoms may be present at birth, and can become more obvious within the first few weeks of life. It is not uncommon for the noisy breathing to get worse before it improves, usually around 4 to 8 months of age. Most children outgrow laryngomalacia by 18 to 20 months of age.
When do you use a Miller laryngoscope?
The straight Miller laryngoscope blade is traditionally recommended for intubation in infants, due to the large size and flexibility of the infant epiglottis.
When do you intubate a patient with Covid?
A patient who is breathing comfortably and able to talk in full sentences is unlikely to be in such distress that urgent intubation is needed. The Cabrini Respiratory Strain Scale measures these observable variables and is being studied as a decision tool for invasive ventilation.
What is the difference between a bougie and a stylet?
A stylet is a malleable metal rod placed inside the endotracheal tube to facilitate its passage into the trachea. A bougie is a thin plastic rod that is passed into the trachea, over which the endotracheal tube is inserted.
When intubating with a bougie device when should the endotracheal tube be loaded onto the Bougie?
Bougie-assisted Endotracheal Intubation
when used to confirm endotracheal placement the bougie is passed down the endotracheal tube and there should be ‘hold up’ at 30-40cm depth, if this does not occur the bougie is likely to be in the esophagus.
Can you oxygenate through a bougie?
Bougies are also commonly used during endotracheal tube or tracheostomy exchange, much like an airway exchange catheter. Bougies, in contrast to airway exchange catheters, do not have a central lumen and can therefore not be used to oxygenate the patient.
Is being intubated painful?
Conclusion: Being intubated can be painful and traumatic despite administration of sedatives and analgesics. Sedation may mask uncontrolled pain for intubated patients and prevent them from communicating this condition to a nurse.
What is the difference between being intubated and 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 many attempts do you get for intubation?
Repeated attempts at tracheal intubation may reduce the likelihood of effective airway rescue with a SAD. These guidelines recommend a maximum of three attempts at intubation; a fourth attempt by a more experienced colleague is permissible.
Is intubation life support?
“Intubating a patient and putting them on a ventilator to help them breathe definitely means they are being put on life support, which is very scary to think about when it’s you or your loved one needing that treatment.”
How long does it take to learn to intubate?
It is estimated that to place an endotracheal tube (ETT) successfully during CPR in 30-60 seconds using direct laryngoscopy would take 3-5 years of experience and 137-243 endotracheal intubations (ETI).
Does Trendelenburg increase or decrease blood pressure?
Abstract. Background: Little evidence indicates that changing a patient’s body position to the Trendelenburg (head lower than feet) or the modified Trendelenburg (only the legs elevated) position significantly improves blood pressure or low cardiac output.
What is Fowler’s position used for?
Fowler’s position is the most common position for patients resting comfortably, whether in-patient or in the emergency department. Also known as sitting position, Fowler’s patient positioning is typically used for neurosurgery and shoulder surgeries.
Does Trendelenburg decrease heart rate?
An important issue in the reliability of the Trendelenburg maneuver to predict fluid responsiveness is related to baroreflex activation in this position, leading to systemic vasodilation, decreased heart rate and myocardial contractility.
What is The Sims position used for?
Sims’ position, named after the gynaecologist J. Marion Sims, is usually used for rectal examination, treatments, enemas, and examining women for vaginal wall prolapse. It is performed by having the person lie on their left side, left hip and lower extremity straight, and right hip and knee bent.
What position should a patient with low blood pressure be positioned in?
One intervention commonly used to manage severe hypotension is Trendelenburg positioning, defined as a position in which the head is low and the body and legs are on an inclined or raised plane.
What is the difference between Sims position and left lateral position?
Sim’s Position
The Sims’ position is a variation of the left lateral position. The patient is usually awake and helps with the positioning. The patient will roll to his or her left side. Body restraints are used to safely secure the patient to the operating table.
What is Elm intubation?
Bimanual laryngoscopy using external laryngeal manipulation (ELM) is the single most practical and effective airway management technique for facilitating intubation during direct laryngoscopy.
How do you do a Sellick maneuver?
The Sellick Maneuver is performed by applying gentle pressure to the anterior neck (in a posterior direction) at the level of the Cricoid Cartilage. The Maneuver is most often used to help align the airway structures during endotracheal intubation.
What is a gum elastic bougie?
The gum elastic bougie is a urinary catheter that was originally used for dilation of urethral strictures. This catheter was used as an endotracheal tube introducer (to facilitate difficult tracheal intubation) by Sir Robert R. Macintosh2in 1949.
How do I know if my trach is cuffed or uncuffed?
If the tracheostomy tube has a pilot line and pilot balloon, this is an indicator that the patient has a cuffed tracheostomy tube. The flange of the tracheostomy tube also indicates if the tracheostomy tube has a cuff in place.
When will the cuff be inflated on a tracheostomy tube?
Inflate cuff 24 hours following initial tracheostomy tube placement (prevents accumulation of subcutaneous air and aspiration of secretions) Manual assisted ventilation/mechanical ventilation. Meals or nasogastric tube feedings for 30 minutes after if problems with aspiration are anticipated.
Should trach cuff be inflated during suctioning?
The definition of aspiration is when any food, liquid, or other matter passes below the vocal folds. Therefore, the cuff cannot prevent aspiration as it is located below the vocal folds (see Figure 1). When neither mechanical ventilation or a risk of gross aspiration is present, the cuff should be deflated.

How do I know what size intubation tube I need?
The endotracheal tubes size (“give me a 6.0 tube”) refers to its internal diameter in millimeters (mm). The ETT will typically list both the inner diameter and outer diameter on the tube (for example, a 6.0 endotracheal tube will list both the internal diameter, ID 6.0, and outer diameter, OD 8.8).
Can a nurse insert an endotracheal tube?
Intubation can be performed by various healthcare professionals, such as physicians, Anesthesiologists, Nurse Anesthetists, and other Advance Practice Registered Nurses (APRNs).
What is the difference between a direct and indirect laryngoscopy?
Background. Direct laryngoscopy is the method currently used for tracheal intubation in children. It occasionally offers unexpectedly poor laryngeal views. Indirect laryngoscopy involves visualizing the vocal cords by means other than obtaining a direct sight, with the potential to improve outcomes.
