Preanesthetic assessment (also called preanesthesia evaluation, pre-anesthesia checkup (PAC) or simply preanesthesia) is a medical check-up and laboratory investigations done by an anesthesia provider or a registered nurse before an operation, to assess the patient's physical condition and any other medical problems or diseases the patient might have. [1]
A laryngeal mask airway has an airway tube that connects to an elliptical mask with a cuff. The cuff can either be an inflating type (achieved after insertion using a syringe of air), or self-sealing. [citation needed] A laryngeal mask airway must first be completely sterilised (it may be reused many times). [1]
An important aspect of pre-anaesthetic evaluation is an assessment of the patient's airway, involving inspection of the mouth opening and visualisation of the soft tissues of the pharynx. [19] The condition of teeth and location of dental crowns are checked, and neck flexibility and head extension are observed.
Furthermore, before a qualified anesthesia professional performs PSA, an Informed consent should be completed. [4] Airway assessment is one of the most important parts of the physical exam when done as part of the pre-procedure work-up.
Basic airway management is a concept and set of medical procedures performed to prevent and treat airway obstruction and allow for adequate ventilation to a patient's lungs. [1] This is accomplished by clearing or preventing obstructions of airways.
CRNAs communicate with the surgeon and interdisciplinary team to design an anesthesia plan for a patient. Some procedures that nurse anesthetists offer include: Evaluation of the patient prior to anesthesia; Physical assessment and pre-operative teaching before the anesthesia; Administering anesthesia; Airway management [15]
Airway, breathing, and circulation, therefore work in a cascade; if the patient's airway is blocked, breathing will not be possible, and oxygen cannot reach the lungs and be transported around the body in the blood, which will result in hypoxia and cardiac arrest. Ensuring a clear airway is therefore the first step in treating any patient; once ...
Advanced airway management can be performed "blindly" or with visualization of the glottis by using a laryngoscope. Advanced airway management is frequently performed in the critically injured, those with extensive pulmonary disease, or anesthetized patients to facilitate oxygenation and mechanical ventilation.
