  • Cricothyrotomy
    NURSING Cricothyrotomy: Assisting with PRACTICE & SKILL What is Cricothyrotomy? › Cricothyrotomy (CcT; also called thyrocricotomy, inferior laryngotomy, and emergency airway puncture) is an emergency surgical procedure that is performed to secure a patient’s airway when other methods (e.g., nasotracheal or orotracheal intubation) have failed or are contraindicated. Typically, CcT is performed only when intubation, delivery of oxygen, and use of ventilation are not possible • What: CcT is a type of tracheotomy procedure used in emergency situations (e.g., when a patient is unable to breathe through the nose or mouth). The two basic types of CcT are needle CcT (nCcT) and surgical CcT (sCcT). Both types of CcTs result in low patient morbidity when performed by a trained clinician. Compared with the sCcT method, the nCcT method requires less time to set up and is associated with less bleeding and airway trauma • How: Ideally, a CcT is performed within 30 seconds to 2 minutes by making an incision or puncture through the skin and the cricothyroid membrane (i.e., the thin part of the larynx [commonly called the voice box])that is between the cricoid cartilage and the thyroid cartilage) into the trachea –An nCcT is a temporary emergency procedure that involves the use of a catheter-over-needle technique to create a small opening. Because it involves a relatively small opening, it is not suitable for use in extended ventilation and should be followed by the performance of a surgical tracheotomy when the patient is stabilized. nCcT is the only type of CcT that is recommended for children who are under 10 years of age - A formal tracheotomy is a more complex procedure in which a surgical incision is made in the lower part of the neck, through the thyroid gland, and into the trachea.

    Vocal Cord Dysfunction JAMES DECKERT, MD, Saint Louis University School of Medicine, St. Louis, Missouri LINDA DECKERT, MA, CCC-SLP, Special School District of St. Louis County, Town & Country, Missouri Vocal cord dysfunction involves inappropriate vocal cord motion that produces partial airway obstruction. Patients may present with respiratory distress that is often mistakenly diagnosed as asthma. Exercise, psychological conditions, airborne irritants, rhinosinusitis, gastroesophageal reflux disease, or use of certain medications may trigger vocal cord dysfunction. The differential diagnosis includes asthma, angioedema, vocal cord tumors, and vocal cord paralysis. Pulmo- nary function testing with a flow-volume loop and flexible laryngoscopy are valuable diagnostic tests for confirming vocal cord dysfunction. Treatment of acute episodes includes reassurance, breathing instruction, and use of a helium and oxygen mixture (heliox). Long-term manage- ment strategies include treatment for symptom triggers and speech therapy. (Am Fam Physician. 2010;81(2):156-159, 160.

  • Nerve Blocks for Surgery on the Shoulder, Arm Or Hand
    Nerve blocks for surgery on the shoulder, arm or hand Information for patients and families First Edition 2015 www.rcoa.ac.uk/patientinfo Nerve blocks for surgery on the shoulder, arm or hand This leaflet is for anyone who is thinking about having a nerve block for an operation on the shoulder, arm or hand. It will be of particular interest to people who would prefer not to have a general anaesthetic. The leaflet has been written with the help of patients who have had a nerve block for their operation. Throughout this leaflet we have used the above symbol to highlight key facts. Brachial plexus block? The brachial plexus is the group of nerves that lies between your neck and your armpit. It contains all the nerves that supply movement and feeling to your arm – from your shoulder to your fingertips. A brachial plexus block is an injection of local anaesthetic around the brachial plexus. It ‘blocks’ information travelling along these nerves. It is a type of nerve block. Your arm becomes numb and immobile. You can then have your operation without feeling anything. The block can also provide excellent pain relief for between three and 24 hours, depending on what kind of local anaesthetic is used. A brachial plexus block rarely affects the rest of the body so it is particularly advantageous for patients who have medical conditions which put them at a higher risk for a general anaesthetic. A brachial plexus block may be combined with a general anaesthetic or with sedation. This means you have the advantage of the pain relief provided by a brachial plexus block, but you are also unconscious or sedated during the operation.

  • Diagnostic Direct Laryngoscopy, Bronchoscopy & Esophagoscopy
    Post-Operative Instruction Sheet Diagnostic Direct Laryngoscopy, Bronchoscopy & Esophagoscopy Direct Laryngoscopy: Examination of the voice box or larynx (pronounced “lair-inks”) under general anesthesia. An instrument called a laryngoscope is carefully placed into the mouth and used to visualize the larynx and surrounding structures. Bronchoscopy: Examination of the windpipe below the voice box in the neck and chest under general anesthesia. A long narrow telescope is passed through the larynx and used to carefully inspect the structures of the trachea and bronchi. Esophagoscopy: Examination of the swallowing pipe in the neck and chest under general anesthesia. An instrument called an esophagoscope is passed into the esophagus (just behind the larynx and trachea) and used to visualize the mucus membranes and surrounding structures of the esophagus. Frequently a small biopsy is taken to evaluate for signs of esophageal inflammation (esophagitis). What to Expect: Diagnostic airway endoscopy procedures generally take about 45 minutes to complete. Usually the procedure is well-tolerated and the child is back-to-normal the next day. Mild throat or tongue discomfort may persist for a few days after the procedure and is usually well-controlled with over-the-counter acetaminophen (Tylenol) or ibuprofen (Motrin). Warning Signs: Contact the office immediately at (603) 650-4399 if any of the following develop: • Worsening harsh, high-pitched noisy-breathing (stridor) • Labored breathing with chest retractions or flaring of the nostrils • Bluish discoloration of the lips or fingernails (cyanosis) • Persistent fever above 102°F that does not respond to Tylenol or Motrin • Excessive coughing or respiratory distress during feeding • Coughing or throwing up bright red blood • Excessive drowsiness or unresponsiveness Diet: Resume baseline diet (no special postoperative diet restrictions).
