Right-sided pneumothorax as a result of a left-sided chest tube

A chest tube translocating the posterior mediastinum: A strange case of malpositioning without complication or injury

Malpositioning of a chest tube is a recognised complication of chest tube insertion. However, cases involving the mediastinum comprise only a fraction of such occurrences, while the complete translocation of the tube through the medisastinum is only noted in three published cases. This case report describes a case of complete translocation of the mediastinum during chest tube insertion to resolve a pneumothorax. It examines the possibility of an occult natural pathway in the posterior mediastinum of some patients based on the ease at which the tube crossed the mediastinum, the immediate resolution of patient symptoms and the absence of injury or complications from the event to the patient.

Tube Thoracostomy: A Structured Review of Case Reports and a Standardized Format for Reporting Complications

INTRODUCTION

Although seemingly straightforward, tube thoracostomy (TT) has been associated with complication rates as high as 30 %. A lack of a standardized nomenclature for reporting TT complications makes comparison and evaluation of reports impossible. We aim to develop a classification method in order to standardize the reporting of complications of TT and identify all reported complications of TT and time course in which they occurred to validate the reporting method.

METHODS

A systematic search of MEDLINE, Scopus, EMBASE, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews from each databases inception through November 5, 2013 was conducted. Original articles written in the English language reporting TT complications were searched. This review adhered to preferred reporting items for systematic reviews and meta-analyses (PRISMA) standards. Duplicate reviewers abstracted case reports for inclusion. Cases were then sorted into one of the five complication categories by two reviewers, and in case of disagreements, settled by a third reviewer.

RESULTS

Of 751 papers reporting TT complications, 124 case reports were included for analysis. From these reports, five main categories of TT complications were identified: insertional (n = 65); positional (n = 36); removal (n = 11); infective and immunologic (n = 7); and instructional, educational, or equipment related (n = 5). Placement of TT has occurred in nearly every soft tissue and vascular structure in the thoracic cavity and intra-abdominal organs.

CONCLUSION

Our classification method provides further clarity and systematic standardization for reporting TT complications.

Thoracostomy tubes: A comprehensive review of complications and related topics

Tube thoracostomy (TT) placement belongs among the most commonly performed procedures. Despite many benefits of TT drainage, potential for significant morbidity and mortality exists. Abdominal or thoracic injury, fistula formation and vascular trauma are among the most serious, but more common complications such as recurrent pneumothorax, insertion site infection and nonfunctioning or malpositioned TT also represent a significant source of morbidity and treatment cost. Awareness of potential complications and familiarity with associated preventive, diagnostic and treatment strategies are fundamental to satisfactory patient outcomes. This review focuses on chest tube complications and related topics, with emphasis on prevention and problem-oriented approaches to diagnosis and treatment. The authors hope that this manuscript will serve as a valuable foundation for those who wish to become adept at the management of chest tubes.

Malpositioning of the chest tube across the anterior mediastinum is risky in chronic obstructive pulmonary disease patients with pneumothorax

Malpositioning is one of the most common complications of chest tube insertion and is associated with increased morbidity and mortality. We present two cases of patients with chronic obstructive pulmonary disorder (COPD) in whom malpositioned chest tubes penetrated through the anterior mediastinum to the contralateral pleural cavity, and were later removed without complications. Both patients had a relatively wide retrosternal airspace and received blunt dissection with a trocar for percutaneous chest tube insertion, which may have increased the risk of chest tube penetration through the anterior mediastinum during tube thoracostomy. Further, the precise location of the malpositioned chest tubes could not be confirmed by single-view anteroposterior portable chest radiography, and computed tomography (CT)-scan was more helpful in the diagnosis and management of the cases reported herein.

Diagnosis of malpositioned chest tubes after emergency tube thoracostomy: is computed tomography more accurate than chest radiograph?

OBJECTIVE

The aim of this study was to compare the accuracy between computed tomography (CT) and frontal chest radiography in the diagnosis of malpositioned chest tubes (MCT).

MATERIALS AND METHODS

CT scans positive for MCT between March 2000 and March 2004 were reviewed. Two radiologists assessed for intra- and extrathoracic locations of MCT in CT studies. Two physicians who were blinded to the results of CT scans assessed the frontal chest radiographs for location of chest tubes, within the pleural space or outside pleural space. The results of CT were then compared with the results of frontal chest radiographs. Medical records were also reviewed for function of the chest tubes and any complications induced by MCT.

RESULTS

CT revealed 28 MCT among the 76 chest tubes that were placed in 54 patients. Among the 28 MCT detected by CT, 23 tubes were in the intrathoracic location (20 intraparenchymal; 3 intrafissural) and 5 tubes were in the extrathoracic location (4 in mediastinum; 1 in chest wall). Frontal chest radiographs only revealed six MCT. Among 28 MCT, 16 sufficient, 8 insufficient, and 4 indeterminate functions of the chest tubes were noted from medical charts. One patient complicated with lung abscess, four patients had suffered pleural empyema, and one patient suffered active lung parenchymal bleeding, resulting from MCT.

CONCLUSIONS

CT is more accurate than chest radiograph for the diagnosis of MCT. For selected patients with inadequacy drainage of the tubes and when chest radiograph is noncontributory, CT scan is recommended to clarify the exact location of chest tubes.

Do junior doctors know where to insert chest drains safely?

BACKGROUND

The safe insertion of a chest drain is a skill doctors across specialties require. Incorrect placement can lead to significant morbidity and even mortality.

METHODS

This audit surveyed junior doctors working in a teaching hospital about their specialty and level of experience with intercostal drains. They were then asked to mark on a photograph where they would insert a chest drain for a pneumothorax in a non-emergency situation.

RESULTS

Of the 55 junior doctors surveyed, 45% were outside the safe area of chest drain insertion as defined by the British Thoracic Society. The most common error was a choice of insertion site too low (24%).

CONCLUSIONS

In this audit 45% of juniors surveyed would have placed a chest drain outside the safe triangle recommended by the British Thoracic Society. The common mistake of a choice of insertion site too low should be discussed in postgraduate teaching programmes.

Diagnosis of pneumothorax in critically ill adults

The diagnosis of pneumothorax is established from the patients' history, physical examination and, where possible, by radiological investigations. Adult respiratory distress syndrome, pneumonia, and trauma are important predictors of pneumothorax, as are various practical procedures including mechanical ventilation, central line insertion, and surgical procedures in the thorax, head, and neck and abdomen. Examination should include an inspection of the ventilator observations and chest drainage systems as well as the patient's cardiovascular and respiratory systems.Radiological diagnosis is normally confined to plain frontal radiographs in the critically ill patient, although lateral images and computed tomography are also important. Situations are described where an abnormal lucency or an apparent lung edge may be confused with a pneumothorax. These may arise from outside the thoracic cavity or from lung abnormalities or abdominal viscera inside the chest.

CT diagnosis of malpositioned chest tubes

Insertion of a chest tube into the pleural space is standard management for various pleural disorders. Malpositioning of chest tubes in extrathoracic, intraparenchymal and mediastinal locations and in the fissures is common. Malpositioning results not only in inadequate drainage of air and fluid but may also result in increased morbidity and mortality. Diagnosis of a malpositioned tube is sometimes difficult to establish on a chest radiograph. CT, however, has proven to be extremely accurate in evaluating the position of a chest tube and has often provided additional valuable information with significant therapeutic impact.

Pleural Disease in the Intensive Care Unit

Pleural disease itself is an unusual cause for admission to the intensive care unit (ICU). Pleural complications of diseases and procedures in the ICU are common, however, and the impact on respiratory physiology is additive to that of the underlying cardiopulmonary disease. Pleural effusion and pneumothorax may be overlooked in the critically ill patient due to alterations in radiologic appearance in the supine patient. The development of a pneumothorax in a patient in the ICU represents a potentially life-threatening situation. This article reviews the etiologies, pathophysiology, and management of pleural effusion, pneumothorax, tension pneumothorax, and bronchopleural fistula in the critically ill patient. In addition, we review the potential complications of thoracentesis and chest tube thoracostomy, including re-expansion pulmonary edema.

Selective use of chest tubes in thoracotomies for congenital cardiovascular procedures

BACKGROUND

Advantages and complications have been reported from the use of chest tubes (CT). To reduce the incidence of complications we have employed a selective use of CT in thoracotomy for congenital cardiovascular procedure; ie, in absence of air leaks and fluid to be drained, no CT was inserted.

METHODS

The lung was reexpanded and air evacuated during the chest closure. Early and 6 hours chest roentgenograms were performed on every patient. This study retrospectively reviews the results of this selective approach in 546 patients operated on between 1980 and 1998 mainly for patent ductus arteriosum ligation, pulmonary artery band, aortic coarctation, Blalock-Taussig shunt. Four hundred and eighteen patients did not receive a CT at the initial surgery (group I), and 128 patients received a CT either before or at surgery (group II).

RESULTS

40 patients in group I developed an air or fluid collection large enough to require a CT. Only one patient had complication, from an undetected hemothorax. Nine patients in group II required another CT, and one patient developed a pneumothorax upon pulling out the CT. No death in either group was related to the use or lack of use of the CT. A total of 378 CTs and collecting chambers were saved.

CONCLUSIONS

A selective approach to the use of CT in thoracotomies for cardiovascular procedures can be employed with minimal complications, more comfort for the patient, and cost savings.

Analysis of tube thoracostomy performed by pulmonologists at a teaching hospital

STUDY OBJECTIVE

To evaluate all tube thoracostomies (TTs) done by pulmonary/critical care fellows and attending physicians in the Medical University of South Carolina's health-care system documenting patient demographics, indication for placement, size and characteristics of the tube, and associated problems.

DESIGN

Prospective.

SETTING

University health-care system, including a university hospital, a Veterans Affairs hospital, and a county hospital.

PATIENTS

All adult patients requiring consultation by a member of the pulmonary/critical care staff for a tube thoracostomy.

RESULTS

One hundred twenty-six tube thoracostomies were performed over a 24-month period in 91 patients. The most common initial indication for a TT was pneumothorax (69/103, 67%). Overall mortality in the patient population was 35% (32/91). Early problems (< 24 hours following placement) occurred in 3% (4/126); late problems (> 24 h after placement) occurred in 8% (10/126). Problems occurred in 36% (4/11) of small-bore tube placements vs 9% (10/115) of standard TT placements (p=0.02).

CONCLUSIONS

Tube thoracostomy can be safely performed by pulmonologists with relatively few associated problems.

Selected topics in chest trauma

Trauma is the leading cause of death of young adults in the United States, and chest trauma is one of the leading causes of trauma-related fatalities. This article presents an approach to the radiological evaluation and diagnosis of pneumothorax, pneumomediastinum, traumatic aortic rupture, and thoracic spine injuries. Also discussed is the radiological assessment of vascular catheters, endotracheal tubes, and thoracostomy tubes.
