1/39. Traumatic fracture of the hyoid bone: three case presentations of cardiorespiratory compromise secondary to missed diagnosis.hyoid bone fractures secondary to blunt trauma other than strangulation are rare (ML Bagnoli et al., J Oral Maxillofac Surg 1988; 46: 326-8), accounting for only 0.002 per cent of all fractures. The world literature reports only 21 cases. Surgical intervention involves airway management, treatment of associated pharyngeal perforations, and management of painful symptomatology. The importance of hyoid fracture, however, rests not with the rarity of it, but with the lethal potential of missed diagnosis. We submit three cases with varying presentations and management strategies. All three of our cases incurred injury by blunt trauma to the anterior neck. Two patients required emergent surgical airway after unsuccessful attempts at endotracheal intubation. One patient presented without respiratory distress and was managed conservatively. After fracture, the occult compressive forces of hematoma formation and soft tissue swelling may compromise airway patency. It is our clinical observation that hypoxia develops rapidly and without warning, leading to cardiorespiratory collapse. With endotracheal intubation prohibited by obstruction, a surgical airway must be established and maintained. Recognition of subtle clinical and physical findings are critical to the diagnosis of laryngotracheal complex injuries and may be life-saving in many instances. To ensure a positive outcome, a strong degree of suspicion based on mechanism of injury is mandated.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/39. Lingual tonsillectomy for refractory paroxysmal cough.Historically, the lingual tonsils are the most neglected members of Waldeyer's ring. They are often overlooked even in a thorough head and neck exam because of their anatomic location and the ambiguous constellation of symptoms which they produce when they are diseased or enlarged. The lingual tonsils have been reported to be associated with a variety of upper aerodigestive tract symptoms including odynophagia, dysphagia, otalgia, globus, halitosis, chronic cough, and dyspnea. Many patients with lingual tonsillar pathology may undergo extensive work-up for some of these non-specific upper airway complaints by their primary physician before referral to an otolaryngologist. Consequently, the diagnosis of lingual tonsillar disease requires a high index of suspicion and a thorough physical exam including evaluation of the tongue base and hypophaynx with indirect mirror or fiberoptic exam. In order to draw attention to this frequently unrecognized entity, we present a case report of a child with chronic cough resulting from lingual tonsillar hypertrophy.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
3/39. Heliox in upper airway obstruction.The use of a helium-oxygen (heliox) mixture in patients with airway obstruction was used as early as the 1930s. Although heliox does not resolve airway obstruction, it decreases airway resistance providing time to allow other treatments to become therapeutic, and thus, possibly preventing the need for intubation and mechanical ventilation. Despite new and advanced treatment options in airway obstruction, heliox continues to be a choice for treatment. It is important for critical care nurses to understand the rationale for the use of heliox, the mechanism of action and administration of heliox. Through a case study, the authors discuss the physical properties of helium and its use in airway obstruction. nursing management of patients receiving heliox is also reviewed.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
4/39. Airway compromise secondary to lingual hematoma complicating administration of tissue plasminogen activator for acute ischemic stroke.Hemorrhagic complications of tissue plasminogen activator (tPA) are well known. We report a case of a lingual hematoma that developed after tPA administration for an acute ischemic stroke that necessitated orotracheal intubation to maintain the patient's airway. This case demonstrates the need for thorough preadministration physical examination, as well as careful monitoring during infusion and after administration of this potent therapeutic agent.- - - - - - - - - - ranking = 8.2586576139307keywords = physical examination, physical (Clic here for more details about this article) |
5/39. Internal carotid artery pseudoaneurysm masquerading as a peritonsillar abscess.Blunt carotid arterial injuries are uncommon. Motor vehicle crashes are the most frequent cause, but this type of vascular injury can be secondary to any direct blow to the neck, intraoral trauma, or strangulation. Types of vascular injuries include dissection, pseudoaneurysm, thrombosis, rupture, and arteriovenous fistula formation. patients with pseudoaneurysm of the internal carotid artery will usually present with neurologic complaints, ranging from the minor to complete stroke. On physical examination, neck hematoma, bruits, pulsatile neck mass, or a palpable thrill may be found. However, in 50% of cases, no external signs of neck trauma are observed. Onset of symptoms may occur within a few hours to several months after the initial injury. angiography is considered the gold standard for diagnosis, but carotid Doppler ultrasound recently has been shown to be very sensitive in detecting these types of injuries. Treatment of pseudoaneurysm is often surgical, with endovascular stenting.- - - - - - - - - - ranking = 8.2586576139307keywords = physical examination, physical (Clic here for more details about this article) |
6/39. A huge epiglottic cyst causing airway obstruction in an adult.An epiglottic cyst causing airway obstruction is rare in an adult. Early definitive diagnosis and management obviate an unnecessary tracheostomy. We report a case of a 64-year-old woman who arrived at our hospital with progressive stridor and foreign body sensation when swallowing for 6 weeks. A hot potato voice and biphasic stridor were remarkable upon physical examination. Indirect mirror and fibroscopic examination revealed a huge epiglottic cyst. The neck lateral X-ray and computed tomography scan demonstrated a huge cystic mass over the epiglottis. A 2.5 x 3.0 cm cystic mass was removed with endoscopic CO2 laser after needle decompression. The patient was discharged on the third day after surgery without complications. An epiglottic cyst in an adult seldom causes upper airway obstruction and is easily ignored by clinicians. We emphasize that complete airway evaluation including routine check-up of the larynx is mandatory for patients with intractable obstructive airway disease. Endoscopic laser surgery is effective in the surgical removal of an epiglottic cyst.- - - - - - - - - - ranking = 8.2586576139307keywords = physical examination, physical (Clic here for more details about this article) |
7/39. Cricoarytenoid arthritis: a cause of acute upper airway obstruction in rheumatoid arthritis.PURPOSE: To report acute upper airway obstruction due to cricoarytenoid arthritis, a well known but uncommon complication of rheumatoid arthritis. CLINICAL FEATURES: We report the case of a 70-yr-old female scheduled for a colostomy who had been suffering from rheumatoid arthritis for 17 years. Preoperative history and physical examination revealed no cardiopulmonary compromise. anesthesia was induced while an assistant immobilized the cervical spine and an atraumatic intubation was performed. Surgery was uneventful. Muscle paralysis was reversed, demonstrated by normalization of the train-of-four response, and the patient was extubated awake. Shortly postextubation, the patient developed inspiratory stridor, which disappeared after a second dose of neostigmine. The patient was transported to the postanesthesia care unit. Just prior to arrival the patient once again developed inspiratory stridor, became distressed, and oxygen saturation decreased. Direct laryngoscopy followed by a nasal fibreoptic examination of the larynx was performed. Cricoarytenoid arthritis secondary to rheumatoid arthritis with airway compromise was diagnosed. An uneventful awake tracheostomy was performed. The patient was discharged on day ten with a colostomy and a tracheostomy in place. One month postdischarge the patient's trachea was decannulated. On follow-up, a normal voice and mobile cords were observed. CONCLUSION: Cricoarytenoid arthritis is an infrequent complication of rheumatoid arthritis. A thorough history and physical examination are necessary to recognize signs and symptoms of cricoarytenoid arthritis. Prompt recognition of airway obstruction due to cricoarytenoid arthritis is essential for appropriate management.- - - - - - - - - - ranking = 16.517315227861keywords = physical examination, physical (Clic here for more details about this article) |

9/39. Difficult airway in a child with spinal muscular atrophy type I.Spinal muscular atrophy (SMA) type I is a relatively common inherited neuromuscular disease of hypotonic newborns, but is not associated with craniofacial abnormalities. There is nothing in the literature about difficult intubation in patients affected by this disease. We report a case of 34-month-old girl with SMA type I who was scheduled for emergency endoscopic laser treatment of tracheal stenosis caused by granulations. tracheostomy was performed at 17 months of age and before this, the orotracheal tube was changed periodically without difficulty. For this laser treatment, orotracheal intubation was required. Preoperative physical examination revealed micrognathia and class II malocclusion. Opening her mouth was not difficult. Although difficult orotracheal intubation was predictable, we attempted to intubate her trachea as usual, but could not visualize the epiglottis. We decided to proceed with retrograde intubation, one of the standard techniques employed in a child with a difficult airway, via the tracheostome. A feeding nasogastric catheter was used as a guide catheter, and our strategy was successful. In this study we report a case of difficult airway in a child with SMA type I. The relationship between SMA type I with a tracheostome and difficult airway are discussed.- - - - - - - - - - ranking = 8.2586576139307keywords = physical examination, physical (Clic here for more details about this article) |
10/39. Abnormalities of surfactant in children with recurrent cyanotic episodes.The mechanism of recurrent cyanotic episodes in infants and children is not known, but a deficiency of surfactant is a possible cause. We have measured the amount of surfactant collected by bronchoalveolar lavage from two children with recurrent cyanotic episodes and from two controls with anatomical airway obstructions. We also assessed the physical properties of the surfactant by changing the surface area (A) of a monolayer and measuring its surface tension (gamma). The cases had lower amounts of surfactant extracted, which could explain some of the abnormalities of the gamma/A loops. However, the finding that the cases had reversed loops (ie, the surface tension is higher during monolayer compression than during expansion) shows that there is also a qualitative abnormality. These features suggest a possible diagnostic test if not a mechanism for this disorder.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
