Case Series on Barotrauma in COVID-19 Infection Patients

As COVID-19 emerged in the world, there was a high prevalence of intubation and intensive care admissions. Many cases of barotrauma were reported in those patients. This condition is caused by alveoli rupture, which causes the air to enter the surrounding extra-alveolar spaces. It mainly happens in intubated patients. Here, we report 14 cases of barotrauma in COVID-19 patients, which appeared either spontaneously or after receiving non-invasive ventilation, some of the patients presented initially with mild-moderate forms of the disease in terms of severity. Developing barotrauma causes a management challenge in COVID-19 patients, where the patients might require invasive mechanical ventilation afterwards, which is a difficult situation. Lung protective measures should be used to reduce the risk of barotrauma in all patients as it is associated with increased mortality.

Minimally Invasive Video-assisted Mitral Valve Replacement with a Right Chest Small Incision in Patients Aged Over 65 Years

OBJECTIVE

To analyze and summarize the clinical safety and feasibility of minimally invasive video-assisted mitral valve replacement via a right thoracic minimal incision in patients aged over 65 years.

METHODS

The clinical data of 45 patients over 65 years old who had mitral valve disease were analyzed retrospectively from January 2014 to January 2017 at Union Hospital, Fujian Medical University. The patients were divided into two groups; 20 patients in group A, who underwent minimally invasive video-assisted mitral valve replacement via a right thoracic minimal incision, and 25 patients in group B, who underwent conventional mitral valve replacement. We collected and analyzed their relevant clinical data.

RESULTS

The operation was completed successfully in both groups. Compared with group B, group A was clearly superior for postoperative analgesia time, postoperative hospital length of stay, thoracic drainage liquid, blood transfusion, and length of incision. There were no differences between the two groups in postoperative severe complications and mortality. More patients in group B had pulmonary infections and poor incision healing, while more patients in group A had postoperative pneumothorax and subcutaneous emphysema.

CONCLUSION

In patients aged over 65 years, minimally invasive video-assisted mitral valve replacement with a small incision in the right chest had the same clinical safety and efficacy as the conventional method.

[Benign recurrent subcutaneous emphysema of the upper limbs in a teenager]

BACKGROUND

The physiological properties of the interstitial subcutaneous tissue of the limbs could bring the abnormal distribution of air coming from superficial trauma of the skin. We present the case of a young woman who developed subcutaneous emphysema after a superficial trauma and discussed the differential diagnosis and treatment.

CLINICAL CASE

A teenager woman 13 years old had subcutaneous emphysema in the left arm, following the scratch produced by her cat, of two months of evolution, without signs suggestive of local or systemic infection, it was resolved spontaneously during the period of observation. During this period she also presented subcutaneous emphysema in the right arm as a complication of a peripheral venous access performed for the administration of parenteral solutions, in the same way, it resolved spontaneously within a few days.

CONCLUSION

Benign subcutaneous emphysema is a rare clinical condition which should be considered only after the exclusion of other pathologies that require a more aggressive early medical intervention, such as necrotizing fasciitis, which, if not detected in a timely manner, could endanger life.

Challenging Diagnosis of Severe Bilateral Cervicofacial Subcutaneous Emphysema following Root Perforation in a Maxillary Lateral Incisor: A Case Report

Cervicofacial subcutaneous emphysema (CFSE) is a rare complication. CFSE may happen following some dental procedures including root canal therapy and is caused by unintentional entry of air into potential spaces of head and neck. In the current report, a case of extensive bilateral subcutaneous emphysema -following the root perforation of a maxillary anterior tooth- is presented. A 26-year-old woman was referred for further consultation concerning her right maxillary lateral incisor; for which a poor prognosis was considered following an endodontic treatment. There was a history of sudden facial swelling during root canal therapy. With the exacerbation of the problem and experiencing other symptoms, she was hospitalised. CT scan showed bilateral extension and penetration of air into submandibular, peri-orbital and parapharyngeal spaces. Clinical and radiographic evaluations of the maxillary lateral incisor revealed mid-root perforation on its buccal side, which was sealed by MTA. Eventually, the tooth was successfully restored.

[Subcutaneous Emphysema and Pneumomediastinum During a Tooth Extraction]

Subcutaneous emphysema is a possible but rare complication after dental procedures. The condition should be distinguished from other situations, such as hematoma, allergic reaction or angioedema, and infection. We describe the case of a 20-year-old puerperal woman, with multiple dental caries, who developed cervicofacial subcutaneous emphysema complicated by pneumomediastinum, following an incomplete extraction of the lower right second molar. This was diagnosed clinically and through imaging tests, and the situation resolved after hospital admission, with antibiotics and close monitoring. The case underlines the need to diagnose and treat this complication early, because of the risk of airway compromise, air embolism, infection, sepsis and death.

Subcutaneous Emphysema as a Complication of Tonsillectomy: A Systematic Literature Review and Case Report

INTRODUCTION

Subcutaneous and mediastinal emphysema is a rare complication after tonsillectomy. This case presentation and literature review summarizes the existing literature on this unusual complication.

MATERIALS AND METHODS

This study presents a case of a 21-year-old man who developed a cervical subcutaneous emphysema 6 days after tonsillectomy, whereby conservative treatment produced spontaneous resolution. A proper analysis of this case also required undertaking a systematic search in MEDLINE/PubMed and SCOPUS electronic databases concerning this rare complication, without language restrictions.

RESULTS

Based on our criteria, we identified 41 reports including 43 individual cases, in which patients were mostly young and equally distributed between the genders (18 males and 23 females, two unknown). The treatment was mainly conservative and consisted of observation and/or antibiotic therapy.

CONCLUSION

Subcutaneous or mediastinal emphysema is an uncommon complication after tonsillectomy. It is important that clinicians become aware of this rare complication, which requires a close monitoring of the patient.

Spontaneous Retropharyngeal and Mediastinal Emphysema

A 14-year-old girl with no significant medical history presented at Emergency Department with sore throat and odynophagia after one episode of nonviolent coughing. She denied any respiratory distress, voice change, foreign body ingestion, retching, substance abuse, dental procedures, or trauma. She was afebrile with normal oxygen saturation and physical examination including the head and neck was unremarkable with the exception of bilateral neck crepitus without tenderness on palpation. Fiberoptic laryngoscopy revealed a patent laryngeal airway with normal vocal fold movement. Lateral neck X-ray demonstrated a linear air-column in the retropharyngeal space and computed tomography confirmed emphysema involving the retropharyngeal space and mediastinum with no evidence of fluid collection or abscess formation. Spontaneous retropharyngeal and mediastinal emphysema are clinical entities where free air is present within the confines of retropharyngeal space and mediastinum without obvious cause. It is benign and self-limited in nature and allows for conservative management. This case is presented with a review of literature.

Spontaneous Pneumomediastinum: An Unusual Pulmonary Complication in Anorexia Nervosa

Spontaneous pneumomediastinum (PM) is an uncommon condition in which free air enters the mediastinum. This usually occurs either through esophageal tears after vigorous vomiting, or after alveolar rupture subsequent to a rapid increase in intra-alveolar pressure. Spontaneous PM is a rare entity in anorexia nervosa (AN) and self-induced vomiting is often the cause of PM in patients with AN. We experienced a case of spontaneous PM in an anorexic adolescent, in whom vomiting was not the cause of PM.

Whistles and wheezes: don't miss diseases

Upper airway obstruction (UAO) in infants and children has a broad spectrum of presentations including benign self-resolving conditions, from mild croup, to critical life-threatening conditions which, though uncommon now, require prompt recognition and effective multidisciplinary collaborative management to achieve a good outcome. The aim of this article is to highlight the diagnostic and management difficulties in acute UAO in paediatric patients and encourage a problem-solving approach.

Cervicofacial emphysema and pneumomediastinum following dental extraction: case report

BACKGROUND

Pneumomediastinum is commonly caused by iatrogenic injury such as surgery on the cervical planes and chest or by tracheostomy. It is also well known that emphysema may occur after dental treatments using an air turbine drill, but there have been few cases of emphysema which extended to the mediastinum.

CASE PRESENTATION

A 16-year-old boy is presented with subcutaneous emphysema and pneumomediastinum which developed 24 hours after surgery for extraction of an inferior second molar. We first describe history, clinical presentation and radiologic appearance of our patient and then review the literature about oral surgery causing pneumomediastinum.

CONCLUSION

Surgical procedures in oral cavity can lead to the development of emphysema and pneumomediastinum when air turbine dental drills are used. To avoid these complications, air turbine high speed drills should be used only in necessary cases.
