The Dynarex nasopharyngeal airways are Robertazzi style and feature a flared end to prevent the device from getting lost in the patient’s nose. The Dynarex nasopharyngeal airways are Robertazzi style and feature a flared end to prevent the device from getting lost in the patient’s nose. These airways are recommended for semi-conscious and unconscious patients to ensure an open airway. The nasopharyngeal airway kit contains lubricant jelly packages and 9 soft, movable airways in different sizes. Comes with all the necessary components for a caregiver to quickly enter the nasal airway and maintain open airway. Dynarex Corporation was founded in 1967 and is a leading manufacturer of a wide range of disposable medical products. What is a nasopharynx airway from Robertazzi?In medicine, a nasopharynx airway, also known as NPA, nasal trumpet (because of its flared end), or nasal tube, is a type of airway accessory, a tube that is intended to be inserted into the nasal passage to secure an open airway. While nasopharyngeal airway devices are airway accessories for patients who are difficult to ventilate and oxygenate, they only serve as a bridge to a stabilized patient who is breathing unaided, or to a patient who requires safe airway via endotracheal or nasotracheal (NT) intubation. Nasopharyngeal airway maneuvers can be very useful for healthcare professionals when patients with respiratory conditions require adequate airway management. What would cause a nasopharynx airway to be contraindicated?Choosing an OPA over an NPA in patients with an intact gag reflex poses the risk of vomiting and aspiration pneumonia. See also Airway setup and control Airway setup and control Airway management consists of cleaning the upper airway Maintaining an open air duct with a mechanical device Sometimes assisting breathing (see also Overview of respiratory arrest. This may be as serious as intracranial placement of an NPA and is certainly a common problem. Oropharyngeal airway (also known as OPAs, “oral airway,” or “guedel airways,” named after the original designer Arthur Güdel (), and nasopharyngeal airways (also known as NPAs and nasal airways) are used to maintain an open airway.

Laryngeal Mask Airway has been used in paediatric anaesthesia since the 1990's. Clinical practice in paedeatric anaesthesia for Laryngeal Mask Airway removal varies and there is no standard of care. In children removing the Laryngeal Mask Airway under deep inhalational anaesthesia has some advantages compared to awake, but may be associated with higher rate of complications when Laryngeal Mask Airway is removed in supine compared to lateral position. On the other hand deep anaesthesia may cause airway obstruction due to reduction in tone of upper airway muscles in some patients. An oropharangeal airway may prevent this. This aspect had not been studied before and represent a gap in literature. Study Hypothesis: Airway complications associated with Laryngeal Mask Airway removal under deep anaesthesia are same with or without insertion of an oral airway. Alternate hypothesis is that airway complications be less if an air way is inserted at the end of anaesthesia. Objective: The present study was designed to observe any difference in immediate complication after removal of LMA in supine head down position under deep anaesthesia with or without insertion of an oro-pharyngeal airway. Airway complications that we will observe are desaturation <92%, stridor, excessive secretions, laryngospasm, retching, vomiting, coughing, trauma to the soft tissues and damage to the teeth.
An oropharyngeal airway (also known as an oral airway, OPA or Guedel pattern airway) is a medical device called an airway adjunct used in airway management to maintain or open a patient's airway. It does this by preventing the tongue from covering the epiglottis, which could prevent the person from breathing. When a person becomes unconscious, the muscles in their jaw relax and allow the tongue to obstruct the airway.[1] History and usage[edit]The oropharyngeal airway was designed by Arthur Guedel.[2] Oropharyngeal airways come in a variety of sizes, from infant to adult, and are used commonly in pre-hospital emergency care and for short term airway management post anaesthetic or when manual methods are inadequate to maintain an open airway. This piece of equipment is utilized by certified first responders, emergency medical technicians, paramedics and other health professionals when tracheal intubation is either not available, not advisable or the problem is of short term duration.[citation needed] Oropharyngeal airways are indicated only in unconscious people, because of the likelihood that the device would stimulate a gag reflex in conscious or semi-conscious persons. This could result in vomit and potentially lead to an obstructed airway. Nasopharyngeal airways are mostly used instead as they do not stimulate a gag reflex. In general, oropharyngeal airways need to be sized and inserted correctly to maximize effectiveness and minimize possible complications, such as oral trauma. Insertion[edit] OP airways in varying sizes The correct size OPA is chosen by measuring from the first incisors to the angle of the jaw. The airway is then inserted into the person's mouth upside down. Once contact is made with the back of the throat, the airway is rotated 180 degrees, allowing for easy insertion, and assuring that the tongue is secured. An alternative method for insertion, the method that is recommended for OPA use in children and infants, involves holding the tongue forward with a tongue depressor and inserting the airway right side up.[1] The device is removed when the person regains swallow reflex and can protect their own airway, or it is substituted for an advanced airway. It is removed simply by pulling on it without rotation.[1] Usage[edit]Use of an OPA does not remove the need for the recovery position and ongoing assessment of the airway and it does not prevent obstruction by liquids (blood, saliva, food, cerebrospinal fluid) or the closing of the glottis. It can, however, facilitate ventilation during CPR (cardiopulmonary resuscitation) and for persons with a large tongue. Key risks of use[edit]The main risks of its use are:[3]

What is the possible complication of the inserted oropharyngeal is too long?An inappropriately sized airway can also cause laryngospasm (i.e., too big). Lastly, damage to the oral structures or dentition can also result from oropharyngeal airway insertion.
What can happen if the oropharyngeal airway is too large?Too large an oral airway will either obstruct the glottis or may cause coughing, gagging, or laryngospasm in a patient who is not deeply anesthetized. Too small an oral airway will push the tongue posteriorly and make the airway obstruction worse.
What is the potential complication of using a nasopharyngeal airway that is too long?When the NPA is too long for the patient, it can create a direct route of ventilation of the stomach, causing gastric distention, increasing vomiting risk, and decreasing oxygenation and ventilation of the lungs.
What is a potential complication of inserting an oropharyngeal airway that is too small ACLS?It may obstruct the larynx or cause trauma to the laryngeal structures. What if the OPA that you have inserted is too small or inserted incorrectly? it may push the base of the tongue posteriorly and obs the airway.
