Tube Thoracostomy Outcomes in COVID-19 Patients

Background: SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) is an extremely infectious virus causing COVID-19 illness. Respiratory failure is a consequence of COVID-19 illness related pneumonia, in which mechanical ventilation and endotracheal intubation are essential. Barotrauma is a chief complication due to mechanical ventilation, in which pneumothorax was established in 25% of COVID-19 barotrauma patients. The majority of complicated COVID-19 cases with a pleural effusion or pneumothorax require a thoracostomy. Objective: To recognize and analyse tube thoracostomy consequences in COVID-19 complicated individuals through this pandemic. Patients and Methods: A retrospective study was accomplished in Thoracic Surgery Unit of Elkasr Elaini Medical Center, Cardiothoracic Surgery Department in Cairo University, Cairo, Egypt. We included fifteen COVID-19 individuals entered the ICU in the period between June 2020 and September 2021 requiring thoracic surgery consultation. Non-COVID-19 severe illness and iatrogenic pneumothorax were omitted from this study. Results: Nine pneumothorax cases (73.3%), two surgical emphysema associated with pneumothorax cases (13.3%), three pleural effusion cases (20%) and one hydropneumothorax case (6.7%) as a total of fifteen patients needed thoracic surgery consultation. After tube thoracostomy, there were no harm consequences. From the total number of patients, 12 well improved and discharged (80%) and three were dead (20%) within three days after tube thoracostomy who were mechanically ventilated due to respiratory failure after ARDS. Conclusion: COVID-19 complicated cases needed chest tube insertion is associated with good outcomes and improvement. © 2022, Ain Shams University Faculty of Medicine. All rights reserved.

Limitation of tube thoracostomy in treating pneumothorax in COVID-19 infected patients. A retrospective cohort study.

Background: COVID19 infection is caused by the highly contagious SARS-CoV-2(Severe acute respiratory syndrome coronavirus 2). The first outbreak of this infection was in Wuhan, China in December 2019. Since then, it has spread rapidly across the world, with more than 100000 new cases each day. Among those infected with SARS-COV-2 up to 20% develop severe disease requiring hospitalization. Among those who are hospitalized, one quarter will need ICU admission. Admission to the ICU is due to respiratory failure or pneumonia. The pneumonia associated with COVID19 infection may lead to respiratory failure requiring endotracheal intubation and mechanical ventilation. An important complication of mechanical ventilation is barotrauma. Barotrauma appears to be common in COVID19 patients. Pneumothorax developed in 25% of COVID19 patients who had barotrauma. In COVID19 the percentage of patients with mild symptoms who develop a pleural effusion is 8% compared to 28% in patients who are critically ill. Most of the COVID19 infected that have a pneumothorax or pleural effusion need a thoracostomy. In trauma cases most, thoracic injuries (leading to pneumothorax or hemothorax) are effectively treated with tube thoracostomy. Objectives: First objective is to compare the therapeutic effect of tube thoracostomy on COVID19 infected patients who have pneumothorax or pleural effusion to those non-COVID19 infected patients who had traumatic pneumothorax or pleural effusion treated by tube thoracostomy. Second objective is to study the morbidity associated with tube thoracostomy in COVID19 infected patients who have pneumothorax or pleural effusion. Patients and methods: This study was conducted in Sheikh Khalifa medical city Ajman, United Arab Emirates. It is a descriptive, observational, retrospective cohort study. One hundred patients were recruited from the January 1, 2020 to the December 31, 2020. Patients were divided into two groups. First group includes fifty adult COVID 19 infected patients who had no trauma. Second group includes fifty adult COVID19 infection free patients who had trauma. Inclusion criteria for the first group: COVID 19 infected patients with an age equal to or above 18 years, of both genders, with history of pneumothorax, pleural effusion or both of them, needed insertion of thoracostomy chest tube. Inclusion criteria for the second group: Patients with an age equal to or above 18 years, of both genders, with history of traumatic pneumothorax, pleural effusion (hemothorax) or both of them, needed insertion of thoracostomy chest tube. Exclusion criteria for the first group: Children, Adult COVID19 infected patients who didn't have pneumothorax or plural effusion, adult COVID19 infected patients who had pneumothorax or plural effusion without a need for tube thoracostomy. Exclusion criteria for the second group: Adult non-COVID19 infected patients who had trauma, but didn't have pneumothorax or pleural effusion, adult non-COVID19 infected patients who had traumatic pneumothorax or pleural effusion without a need for tube thoracostomy. The collected data was revised, coded, tabulated and introduced to a PC using Statistical package for Social Science (SPSS 25). Mann Whitney Test (U test) was used to assess the statistical significance of the difference of a non-parametric variable between two study groups. Chi-Square test was used to examine the relationship between two qualitative variables. Fisher's exact test was used to examine the relationship between two qualitative variables when the expected count is less than 5 in more than 20% of cells. Results: Most of patients in trauma group (group 2) were with the age range of 20-40-year (58.8% of patients) P value was significant (<0.001). In COVID 19 infected patients' group (group 1) the age range was 40-60 year (50%of patients). P Value (<0.001) was significant too. Male was the dominant gender in group 2 (96.1% of patients were male), while in group1 (78% of patients were male), P Value was significant (0.007). No co-morbidities (diabetes, hypertension, ischemic heart disease, Asthma and dyslipidemia) were detected in group 2 (0.0%). Co-morbidity were detected in 76% of patients in group 1, P Value was significant (<0.001). Hemothorax occurred in 37.3% of patients in group 2, and no cases of hemothorax was detected in group 1. P Value was significant (<0.001). Complications of chest tube insertion took place in group 2 as follows; tube malposition in 13.7% of patients, tube blockade in 3.9% of patients. The percentage in group 1 was as follows tube malposition in 16% of patients, tube blockade in 18%. The difference between the two was not significant for tube malposition (P value 0.748) and significant for tube blockade (P value 0.023). Subcutaneous emphysema occurred in 15.7% of patients in group 2 and in 15.7% of patients in group 1. The difference was not significant (P value was 0.118). Acquired bronchopleural fistula occurred 2.0% of group 1 cases. No cases of this fistula were documented in group 2. Number of chest tubes needed to be inserted in group 2 patients was as follows (one chest tube in: 74.5% of patients, two chest tubes in: 23.5% of patients. Three chest tubes or more in 2% of patients). While in group1 patients' number of chest tubes needed to be inserted was (one in 56% of patients, two in 30% of patients. Three or more in 14% of patients). The difference was significant only in those who required insertion of three chest tubes or more (P value was 0.028). The median duration needed to keep a chest tube was 3 days in group 2, and 7 days in group 1. The difference between the two was significant (P value was 0.000). Death was the fate of 3.9% of patients in group 2 and in 64% of patients in group 1. The difference was significant (P value was< 0.001). Conclusion: Therapeutic effect of tube thoracostomy in treating Adult COVID19 patients who had pneumothorax or pleural effusion is less than that used in treating trauma non-COVID19 patients who had pneumothorax or plural effusion. Morbidity and mortality related to tube thoracostomy applied to treat pneumothorax or pleural effusion in adult COVID19 patients is more than that in trauma non COVID 19 patients.

Reduced survival in patients requiring chest tubes with COVID-19 acute respiratory distress syndrome.

Background: Numerous complications requiring tube thoracostomy have been reported among critically ill patients with COVID-19; however, there has been a lack of evidence regarding outcomes following chest tube placement. Methods: We developed a retrospective observational cohort of all patients admitted to an intensive care unit (ICU) with confirmed COVID-19 to describe the incidence of tube thoracostomy and factors associated with mortality following chest tube placement. Results: In total, 1705 patients with laboratory confirmed COVID-19 patients were admitted to our ICUs from March 7, 2020, to March 1, 2021, with 69 out of 1705 patients (4.0%) receiving 130 chest tubes. Of these, 89 out of 130 (68%) chest tubes were indicated for pneumothorax. Patients receiving tube thoracostomy were much less likely to be alive 90 days post-ICU admission (52% vs 69%; P < .01), and had longer ICU (30 vs 5 days; P < .01) and hospital (37 vs 10 days; P < .01) lengths of stay compared with those without tube thoracostomy. Patients who received tube thoracostomy and survived at least 90 days post-ICU admission had shorter times to first chest tube insertion (8.5 vs 17.0 days; P = .01) and a nonsignificantly higher static compliance (20.0 vs 17.5 mL/cm H2O; P = .052) at the time of chest tube placement than those who had expired. Logistic regression analysis demonstrated an association between time to first chest tube and decreased survival when adjusted for covariates. Conclusions: Requiring a chest tube in COVID-19 is a negative prognostic end point. Delayed development of chest tube requirement was associated with a decreased survival and could reflect a poor healing phenotype.

Management of spontaneous pneumothorax in patients with COVID-19.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pneumonia may cause cystic features of lung parenchyma which can resolve or progress to larger blebs. Pneumothorax was more likely in patients with neutrophilia, severe lung injury and a prolonged clinical course. The timely diagnosis and management will reduce COVID-19-associated morbidity and mortality. METHODS: We present 11 cases of spontaneous pneumothorax managed with chest tube thoracostomy or high-dose oxygen therapy. Isolated spontaneous pneumothorax was detected in all cases. RESULTS: Eight cases were male and 3 cases were female. There were bilateral ground-glass opacities or pulmonary infiltrates in the parenchyma of the 10 cases. We detected neutrophilia, lymphopaenia and increased C-reactive protein, Ferritin, lactate dehydrogenase, D-Dimer, interleukin-6 levels in almost all cases. Chest tube thoracostomy was sufficient to treat pneumothorax in our 9 of case. In 2 cases, pneumothorax healed with high-dose oxygen therapy. Favipiravir and antibiotic treatment were given to different 10 patients. In our institution, all patients with COVID-19 infection were placed on prophylactic or therapeutic anticoagulation, unless contraindicated. The treatments of patients diagnosed with secondary spontaneous pneumothorax during the pandemic period and those diagnosed with secondary spontaneous pneumothorax in the previous 3 years were compared with the durations of tube thoracostomy performed in both groups. CONCLUSIONS: The increased number of cases of pneumothorax suggests that pneumothorax may be a complication of COVID-19 infection. During medical treatment of COVID-19, pneumothorax may be the only reason for hospitalization. Although tube thoracostomy is a sufficient treatment option in most cases, clinicians should be aware of the difficulties that may arise in diagnosis and treatment.

An Intriguing Case of Pneumoperitoneum In a Patient With COVID-19: Do All Pneumoperitoneum Cases Need Surgery?

Pneumoperitoneum is pneumatosis in the potential space of the abdominal cavity. It is generally considered a surgical emergency and is mostly due to perforated hollow viscus. Rarely, pneumoperitoneum might occur even in the absence of bowel perforation. We hereby present a case of pneumoperitoneum in a patient with COVID-19 pneumonia and pneumomediastinum, which was managed non-surgically.

Protective measures undertaken during chest tube thoracostomy in COVID-19 outbreak.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a newly emerging infectious disease that was first reported in China and has become a worldwide pandemic. Many surgical procedures are continuing to be performed during this state of pandemic as is thoracic surgery. We present six cases of tube thoracostomy in COVID-19 patients and the modifications to the routine surgical technique. METHODS: We serially attached two closed underwater drainage systems (CUDS) together and added a high-efficiency particulate air (HEPA) filter to the port of the second CUDS, because the intrapleural air, which passes through the CUDS into the air in intensive care unit (ICU), may contain high concentrations of 2019 novel coronavirus (2019-nCoV). Second, we attached the chest drain to the first CUDS in order to prevent the spread of virus during the placement of drain into the pleural cavity. Third, just before opening the parietal pleura, ventilation was put on standby mode and the endotracheal tube was clamped to prevent viral dissemination to the environment. Fourth, we covered the incision with a gauze sponge soaked with sterile saline solution during pleural entry, to prevent viral dissemination into the environment. RESULTS: There were a total of six patients enrolled in our study. All these patients were diagnosed with COVID-19. The surgical indication for the chest tube thoracostomy was tension pneumothorax in all six patents. All patients had lung expansion defects and subcutaneous emphysema after intervention. Unfortunately, all of them succumbed to COVID-19, despite best available treatment. There was no COVID-19 infection reported in the healthcare professionals during this study. CONCLUSIONS: Thoracic surgical procedures may cause dissemination of high amounts of 2019-nCoV in the environment and thus are perhaps the most dangerous surgeries to perform. Variations in the thoracic surgical techniques are necessary in order to protect the healthcare providers from COVID-19.

Chest Tube Drainage in the Age of COVID-19.

Patients with COVID-19 are at risk of developing acute respiratory distress syndrome requiring invasive mechanical ventilation. Barotrauma in these patients often leads to clinically significant pneumothorax, which necessitates chest tube thoracostomy. However, given the mode of transmission of the severe acute respiratory syndrome coronavirus 2 virus and the aerosolizing nature of the procedure, special considerations and care must be taken to mitigate the exposure risks to health care personnel. This article discusses the risk mitigation strategies proposed and under review at the authors' institution.

Pleural complications in patients with coronavirus disease 2019 (COVID-19): how to safely apply and follow-up with a chest tube during the pandemic?

OBJECTIVES: Severe acute respiratory syndrome coronavirus 2, a novel coronavirus, affects mainly the pulmonary parenchyma and produces significant morbidity and mortality. During the pandemic, several complications have been shown to be associated with coronavirus disease 2019 (COVID-19). Our goal was to present a series of patients with COVID-19 who underwent chest tube placements due to the development of pleural complications and to make suggestions for the insertion and follow-up management of the chest tube. METHODS: We retrospectively collected and analysed data on patients with laboratory-confirmed COVID-19 in our hospital between 11 March and 15 May 2020. Patients from this patient group who developed pleural complications requiring chest tube insertion were included in the study. RESULTS: A total of 542 patients who were suspected of having COVID-19 were hospitalized. The presence of severe acute respiratory syndrome coronavirus 2 was confirmed with laboratory tests in 342 patients between 11 March and 15 May 2020 in our centre. A chest tube was used in 13 (3.8%) of these patients. A high-efficiency particulate air filter mounted double-bottle technique was used to prevent viral transmission. CONCLUSIONS: In patients with COVID-19, the chest tube can be applied in cases with disease or treatment-related pleural complications. Our case series comprised a small group of patients, which is one of its limitations. Still, our main goal was to present our experience with patients with pleural complications and describe a new drainage technique to prevent viral transmission during chest tube application and follow-up.
