Tool used for intubation

There is no time to go and get them; because if something is happening to a patient the diagnosis must be made and treated immediately. The different kinds of medication are to put patients to sleep or muscle relaxants paralyze muscles. There are also narcotics that are used frequently in anesthesia that require a code number that is recorded to get them. The narcotics are 10 to times more potent than morphine.

Syringes with needles are used to draw out medication as needed. The patient comes into surgery and as they come in syringes are normally ready and medications drawn up. One of the first things given to the patient is a sedative through an IV tube that is in place. The patient is put on the operating table or bed. The patient is then hooked up to the following monitors: heart EKG , and blood pressure cuff. The cuff checks pressure from continuous readings to minute intervals, depending on the interval selected.

The standard of care is that blood pressure needs to be taken a minimum of every five minutes during surgery. There is also a clip attached to a patient's finger that checks the amount of oxygen in the blood. Once the patient is hooked up to all the monitors, they can be put to sleep. The patient is informed during the procedures, what and why it is being done.

There are different techniques and script of what is said before the patient is put to sleep. One example is, "Try to think of a nice place to go on a vacation.

While the patient is thinking, the anesthesiologist begins administering the anesthetic. The anesthetic is in actuality a hypnotic to put the patient to sleep. The patient must be hooked up to the anesthesia machine to stay asleep.

Intubation comes in at this time. During Intubation: When the patient is asleep, they are given a muscle relaxant that relaxes their muscles including the vocal folds to allow them to open up.

A blade and handle is selected for the laryngoscope to visualize the larynx and intubate the patient e. The anesthesiologist places hand on head of patient and pushes down, which picks up their mandible and allows the mouth to open. The tip of the blade is inserted and slid over the tongue to the base of the tongue. Next, the anestesiologist pulls up and away from the patient in a roughly 45 degree angle. The key is to make sure that the patient is definitely asleep before this is done.

The tube is selected at this time. The tube is placed right between the vocal folds and as soon as the top part of the cuff passes the vocal folds the anesthesiologist stops.

Sometimes stylets are used to help in intubation. Video laryngoscopy technique is similar to that of direct laryngoscopy with the special consideration that some video laryngoscope blades may obstruct endotracheal tube passage when a Cormack Lehane grade 1 view full visualization of the glottis is achieved.

In these cases, the Cormack Lehane grade 2 view partial visualization of the glottis allows for easier passage of the endotracheal tube. If the first intubation attempt is unsuccessful, operators must be ready to change their approach and method on subsequent attempts.

A tracheal tube introducer, also called bougie, can be used if the initial attempt is unsuccessful. The bougie is a flexible device with an anteriorly angulated tip that is introduced in the airway when vocal cord visualization is poor. The introduction of the bougie allows for indirect identification of the cartilaginous ridges of the anterior airway.

The endotracheal tube slides over the bougie and passes the vocal cords. Tracheal tube introducers may be considered for the first attempt in patients with an anticipated difficult airway.

After the endotracheal tube is passed through the vocal cords, the cuff is inflated using a 5 cc or 10 cc syringe filled with air. The stylet is removed, and the proximal end of the endotracheal tube is connected to the carbon dioxide monitor and the ventilation device. Traditionally, the desired depth from the incisors to the distal tip of the endotracheal tube is 21 and 23 cm in women and men, respectively.

Although the preferred distance appears to correlate more with height than gender. After placing the endotracheal tube, it is essential to confirm its placement in the trachea and position proximal to the carina. End-tidal carbon dioxide monitor is the gold standard to confirm tracheal intubation. To rule out esophageal or hypopharyngeal intubation, an EtCO2 monitor measures the expired carbon dioxide with respiration.

Assessment for intubation should take into consideration potential complications. Hypoxemia is a feared complication of intubation that may be precipitated by multiple attempts with poor oxygenation between attempts, misplaced endotracheal tubes, and failed intubation.

Oxygenation can be optimized by pre-oxygenation and apneic oxygenation. To avoid an unrecognized misplaced endotracheal tube, immediate confirmation of the tube position should take place. In cases of anticipated difficult airways, physicians should consider if RSI, DSI, or awake intubation using direct, video, or fiberoptic laryngoscopy is most appropriate for the patient.

Cardiovascular complications can arise as a result of direct pharyngeal manipulation as well as induction medications. Bradycardia can result from vagal stimulation during direct laryngoscopy. Some sedative medications can cause hypotension that can lead to hemodynamic compromise and cardiac arrest during the intubation of critically ill patients. Appropriate resuscitation before intubation can mitigate some of these risks.

Patients should also have large-bore and reliable intravenous or intraosseous access to administer intubation and resuscitation medications if required. Other complications include laceration to the oropharynx from direct manipulation, trauma to the teeth, and aspiration of vomit or objects from the oropharynx, such as dentures. Complications after intubation include uvular and mucosal necrosis from the pressure of the endotracheal tube against these anatomical structures.

Tracheal rupture is extremely rare but can result from tracheal necrosis from cuff overinflation or direct trauma from the tube or stylet. Using manometry to inflate the cuff to a goal of cm water can prevent some of these complications. Endotracheal intubation is an essential skill for emergency medicine and critical care providers.

Understanding the risks and complications of endotracheal intubation is as important as identifying appropriate candidates as early as possible.

When preparing for endotracheal intubation, providers should optimize positioning, pre-oxygenation, equipment, and team preparation. They should also be ready to perform other methods of intubation if the initial attempt is unsuccessful.

If starting with direct laryngoscopy, providers should have back-up strategies such as video laryngoscopy, bougie, laryngeal mask airway LMA , and cricothyrotomy tools immediately available. Preparation and practice are key to leading the team to successful intubation in the emergency setting.

Author Information Authors Andrea C. Continuing Education Activity Endotracheal intubation is an essential resuscitative procedure in the emergency setting. Anatomy and Physiology The upper airway consists of the oral cavity and pharynx, including the nasopharynx, oropharynx, hypopharynx, and larynx.

Contraindications The risks and benefits of endotracheal intubation should be assessed as would be done with any other procedure. Equipment The following equipment may be needed for both direct and video laryngoscopy: Preparation Intravenous access. Personnel The physician caring for the patient who decides to intubate is likely the person with the appropriate training to lead the team toward successful intubation.

Each tube connects to one of your lungs. The bronchi then continue to divide into smaller and smaller air passages within the lung. Your trachea is made up of tough cartilage, muscle, and connective tissue. Its lining is composed of smooth tissue. Each time you breathe in, your windpipe gets slightly longer and wider.

It returns to its relaxed size as you breathe out. You can have difficulty breathing or may not be able to breathe at all if any path along the airway is blocked or damaged. This is when EI can be necessary. In emergency situations, a paramedic at the scene of the emergency may perform EI.

This instrument is used to see the inside of your larynx, or voice box. Once your vocal cords have been located, a flexible plastic tube will be placed into your mouth and passed beyond your vocal cords into the lower portion of your trachea. In difficult situations, a video camera laryngoscope may be used to give a more detailed view of the airway. Your anesthesiologist will then listen to your breathing through a stethoscope to make sure that the tube is in the right place.

Once you no longer need help breathing, the tube is removed. In some situations, the tube may need to be temporarily attached to a bag. Your anesthesiologist will use the bag to pump oxygen into your lungs. EI keeps your airway open. This allows oxygen to pass freely to and from your lungs as you breathe.

NMBAs are used in the ICU to improve patient -ventilator synchrony, enhance gas exchange, and diminish the risk of barotrauma.

The most common reason for NMBA administration is to facilitate mechanical ventilatory support. Sedation and analgesia for intubation Laryngoscopy and intubation are uncomfortable; in conscious patients, a short-acting IV drug with sedative or combined sedative and analgesic properties is mandatory. Etomidate 0. Propofol -based sedation without endotracheal intubation is safe for ESD procedures in the esophagus and stomach with low anesthesia-related complication rates and short hospital stay.

IV lidocaine is hypothesized to work by two mechanisms: By blunting the cough reflex, and thus the reflexive rise in ICP. By suppressing the "pressor response" - the rise in heart rate and blood pressure caused by a catecholamine release during endotracheal stimulation. What equipment is used for intubation?
