ABSTRACT

BACKGROUND COVID-19 caused by SARS-CoV-2 has become a global pandemic. Diagnosis is based on clinical features, nasopharyngeal swab analyzed with real-time reverse transcription-polymerase chain reaction, and computer tomography (CT) scan pathognomonic signs. The most common symptoms associated with COVID-19 include fever, coughing, and dyspnea. The main complications are acute respiratory distress syndrome, pneumonia, kidney failure, bacterial superinfections, coagulation abnormalities with thromboembolic events, sepsis, and even death. The common CT manifestations of COVID-19 are ground-glass opacities with reticular opacities and consolidations. Bilateral lung involvement can be present, especially in the posterior parts and peripheral areas. Pleural effusion, pericardial effusion, and lymphadenopathy are rarely described. Spontaneous pneumothorax and pneumomediastinum have been observed as complications in patients with SARS-CoV-2 pneumonia during mechanical ventilation or noninvasive positive pressure ventilation, as well as in patients with spontaneous breathing receiving only oxygen therapy via nasal cannula or masks. CASE REPORT We present 2 cases of pneumomediastinum with and without pneumothorax in patients with active SARS-Cov-2 infection and 1 case of spontaneous pneumothorax in a patient with a history of paucisymptomatic SARS-CoV-2 infection. In these 3 male patients, ages 78, 73, and 70 years, respectively, COVID-19 was diagnosed through nasopharyngeal sampling tests and the presence of acute respiratory distress syndrome. CONCLUSIONS Both pneumothorax and pneumomediastinum, although rare, may be complications during or after SARS-CoV-2 infection even in patients who are spontaneously breathing. The aim of this study was to describe an increasingly frequent event whose early recognition can modify the prognosis of patients.

ABSTRACT

Since its introduction in 1985 with Ciaglia, percutaneous tracheostomy (PT) was contraindicated in emergency settings and obesity. However, several case series in the last 20 years have documented the use of PT in life-threatening airway emergencies. We present a case of severe acute airway obstruction in a 66-year-old woman successfully treated with a placement of an awake PT. The woman's glottic obstruction was caused by a recurrent laryngeal neoplasia and revealed by nasoendoscopy. This acute condition required a serious effort from the patient to oxygenate and therefore prevented orotracheal intubation as well as the use of any supraglottic device and/or sedation. Blood aspiration after a first attempt to make a quick access to the tracheal lumen with an emergency cricothyroidotomy, and difficulties in the exact identification of tumor infiltration, led us to perform an awake tracheostomy. Due to elevated risk of airway bleeding, we started with a surgical approach to better identify anatomical structures. After the correct inter-tracheal ring space identification, sudden worsening of clinical symptoms required that we complete the procedure quickly with the aid of a Ciaglia Blue Rhino™-Cook (CBR) tracheostomy kit. At the tracheostomy tube placement, the patient quickly resolved her dyspnea and physiological breathing was restored.

ABSTRACT

OBJECTIVE: We planned a training course for trainees of different specialties with the aim of teaching the skills of a new procedure for performing percutaneous dilatational tracheostomy (PDT) with an ETView tracheoscopic ventilation tube instead of standard bronchoscopy in an ex vivo pig model. METHODS: The endotracheal tube, with a camera-embedded tip, was used as an alternative to standard bronchoscopy for visualization of patient airways. The procedure was performed on a home-made animal model. The participants were asked to perform PDT in three different sessions to improve their dexterity. The primary endpoint was the reduction of complications seen during the different sessions of the training course. The secondary endpoint was the satisfaction of the participants as assessed by an anonymous survey. RESULTS: Thirty-seven residents in anesthesiology and 7 in thoracic surgery in the first 2 years of their training and without any confidence with percutaneous tracheostomy participated in the study. Tracheal cuff lesions and impalement of the tracheal tube were the most observed complications, and were concentrated in the early sessions. A significant reduction in complications and operative time was seen during the ongoing sessions of the course. No lesions of the posterior tracheal wall and only a ring fracture occurred during the last session of the course. All participants were satisfied with the course. CONCLUSIONS: Our course seems to confer the technical skills to perform percutaneous tracheostomy to trainees and instill confidence with the procedure. However, the experience acquired on a training course should be evaluated in clinical practice.

ABSTRACT

OBJECTIVE: The authors assessed the diagnostic accuracy of a new modified Evans blue dye test (MEBDT) as a screening test for aspiration in tracheostomized patients. DESIGN: Monocentric retrospective study performed between October 2013 and December 2015. SETTING: Anesthesia and Intensive Care Unit, Second University of Naples. PARTICIPANTS: Among 62 eligible patients, 5 were excluded. The authors' study population included 57 patients. INTERVENTIONS: Patients underwent both fiberoptic endoscopic examination of the swallow (FEES) and MEBDT to evaluate swallow. The MEBDT results were compared with those of FEES and the diagnostic accuracy of MEBDT was calculated using the FEES as the gold standard. MEASUREMENTS AND MAIN RESULTS: The authors found that both FEES and MEBDT were positive for aspiration in 40 patients (true-positive MEBDT); FEES and MEBDT were negative in 10 (true-negative MEBDT). On the other hand, FEES was positive with an MEBDT negative in 7 patients (false-negative MEBDT), and there were no FEES negative and MEBDT positive (false-positive MEBDT). MEBDT had a sensitivity, specificity, positive, and negative predicted value of 85%, 100%, 100%, and 58.82%, respectively. CONCLUSIONS: MEBDT could be a supplementary diagnostic test for aspiration. Patients with positive MEBDT should not undergo oral feeding, while patients with negative MEBDT should undergo FEES before starting oral feeding.
