Suppurative inflammation of the pleural space.
Presence of pus in a hollow organ or body cavity.
Presence of fluid in the pleural cavity resulting from excessive transudation or exudation from the pleural surfaces. It is a sign of disease and not a diagnosis in itself.
Presence of fluid in the PLEURAL CAVITY as a complication of malignant disease. Malignant pleural effusions often contain actual malignant cells.
An intracranial or rarely intraspinal suppurative process invading the space between the inner surface of the DURA MATER and the outer surface of the ARACHNOID.
The removal of fluids or discharges from the body, such as from a wound, sore, or cavity.
The thin serous membrane enveloping the lungs (LUNG) and lining the THORACIC CAVITY. Pleura consist of two layers, the inner visceral pleura lying next to the pulmonary parenchyma and the outer parietal pleura. Between the two layers is the PLEURAL CAVITY which contains a thin film of liquid.
Endoscopic surgery of the pleural cavity performed with visualization via video transmission.
Solitary or multiple collections of PUS within the lung parenchyma as a result of infection by bacteria, protozoa, or other agents.
Fluid accumulation within the PERICARDIUM. Serous effusions are associated with pericardial diseases. Hemopericardium is associated with trauma. Lipid-containing effusion (chylopericardium) results from leakage of THORACIC DUCT. Severe cases can lead to CARDIAC TAMPONADE.
Surgical procedure involving the creation of an opening (stoma) into the chest cavity for drainage; used in the treatment of PLEURAL EFFUSION; PNEUMOTHORAX; HEMOTHORAX; and EMPYEMA.
Tuberculosis of the serous membrane lining the thoracic cavity and surrounding the lungs.
The concrete oleoresin obtained from Pinus palustris Mill. (Pinaceae) and other species of Pinus. It contains a volatile oil, to which its properties are due, and to which form it is generally used. (Dorland, 28th ed) Turpentine is used as a solvent and an experimental irritant in biomedical research. Turpentine toxicity is of medical interest.
Endoscopic examination, therapy or surgery of the pleural cavity.
One of the halogenated 8-quinolinols widely used as an intestinal antiseptic, especially as an antiamebic agent. It is also used topically in other infections and may cause CNS and eye damage. It is known by very many similar trade names world-wide.
The application of a vacuum across the surface of a wound through a foam dressing cut to fit the wound. This removes wound exudates, reduces build-up of inflammatory mediators, and increases the flow of nutrients to the wound thus promoting healing.
Exudates are fluids, CELLS, or other cellular substances that are slowly discharged from BLOOD VESSELS usually from inflamed tissues. Transudates are fluids that pass through a membrane or squeeze through tissue or into the EXTRACELLULAR SPACE of TISSUES. Transudates are thin and watery and contain few cells or PROTEINS.
Paired but separate cavity within the THORACIC CAVITY. It consists of the space between the parietal and visceral PLEURA and normally contains a capillary layer of serous fluid that lubricates the pleural surfaces.
Plastic tubes used for drainage of air or fluid from the pleural space. Their surgical insertion is called tube thoracostomy.
The production of adhesions between the parietal and visceral pleura. The procedure is used in the treatment of bronchopleural fistulas, malignant pleural effusions, and pneumothorax and often involves instillation of chemicals or other agents into the pleural space causing, in effect, a pleuritis that seals the air leak. (From Fishman, Pulmonary Diseases, 2d ed, p2233 & Dorland, 27th ed)
A collection of watery fluid in the pleural cavity. (Dorland, 27th ed)

Infection of the lung often accompanied by inflammation.
A procedure in which fluid is withdrawn from a body cavity or organ via a trocar and cannula, needle, or other hollow instrument.
An abnormal passage or communication between a bronchus and another part of the body.
Abnormal communication most commonly seen between two internal organs, or between an internal organ and the surface of the body.
Neoplasms of the thin serous membrane that envelopes the lungs and lines the thoracic cavity. Pleural neoplasms are exceedingly rare and are usually not diagnosed until they are advanced because in the early stages they produce no symptoms.
Infections with bacteria of the species STREPTOCOCCUS PNEUMONIAE.
Surgical removal of ribs, allowing the chest wall to move inward and collapse a diseased lung. (Dorland, 28th ed)
INFLAMMATION of PLEURA, the lining of the LUNG. When PARIETAL PLEURA is involved, there is pleuritic CHEST PAIN.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
X-ray visualization of the chest and organs of the thoracic cavity. It is not restricted to visualization of the lungs.
The administration of therapeutic agents drop by drop, as eye drops, ear drops, or nose drops. It is also administered into a body space or cavity through a catheter. It differs from THERAPEUTIC IRRIGATION in that the irrigate is removed within minutes, but the instillate is left in place.

  • The pleura lines the thoracic cavity and comprises the visceral and parietal pleural layers. (
  • 13 Approximately half of solitary fibrous tumors are pedunculated and mobile, sometimes changing locations within the pleural cavity on imaging over time. (
  • Drainage of the pleural cavity was attempted by Hippocrates over 2,000 years ago to treat empyema. (
  • Dr. Navdeep Singh Junior resident Pulmonary medicine DEFINITION  A chest drain is a tube inserted through the chest wall between the ribs and into the pleural cavity to allow drainage of air (pneumothorax), blood (haemothorax), fluid (pleural effusion) or pus (empyema) out of the chest. (
  • An empyema is a collection of pus within an anatomical cavity. (
  • 1 Etiology, Pathogenesis, and Epidemiology Pleural fluid originates in the pleural capillaries (mainly those of the parietal pleura), lymphatics, intrathoracic blood vessels, the interstitial pulmonary space, and the peritoneal cavity. (
  • Using the anesthetic needle and syringe, the physician will insert a needle (aspirate) into the pleural cavity to check for the presence of air or fluid. (
  • Then, an incision is made and a clamp is used to open the pleural cavity. (
  • At this stage, either air or fluid will rush out when the pleural cavity is opened. (
  • The diagnosis for chest tube insertion depends on the primary cause of fluid or air in the pleural cavity. (
  • Chest x rays can readily allow the clinician to view the pleural effusion and can also help to detect pneumothorax, since there is visual proof in the displacement of the tissues covering the lungs as a result of air in the pleural cavity. (
  • The chest tube typically remains secure and in place until imaging studies such as x rays show that air or fluid has been removed from the pleural cavity. (
  • proteins, LDH, glucose, total and differential white loculations were done by using forceps through forceps blood count 'WBCs'), Microbiological assessment channel, lastly the pleural cavity was irrigated by (Gram staining, culture and sensitivity, Ziehel Neelsen normal saline. (
  • 1,2 Alternatively, these devices can be used to deliver intrapleural drug therapy, restore negative pressure in the pleural cavity, or expand a collapsed lung. (
  • The diagnosis of parapneumonic effusion or empyema is based on history and physical examination suggesting pneumonia combined with initial laboratory and chest radiography (CXR) indicating a likely bacterial infection with fluid in the pleural space. (
  • This is a parapneumonic effusion with pus (thick, viscid fluid with high numbers of white blood cells and/or the presence of bacteria) caused by the infection spreading from the lung into the pleural space. (
  • Empyemas always require drainage and are almost always associated with infection of the underlying lung or mediastinum. (
  • Infection with streptococcus bacteria is the most frequent cause of a parapneumonic effusion. (
  • Empyema develops when the infection spreads from the lung into the pleural space. (
  • The most common cause of empyema is extension of bacterial infection of the lung into the pleural space. (
  • Pleural infection is a disease of historical importance and is still a modern menace, with incidences rising in adults and children, and a significant mortality in adults. (
  • Pleural infection is one of the oldest and severest diseases. (
  • The definition of empyema is pus in the pleural space [ 6 ], although most clinical trials and studies use the term pleural infection to encompass both empyemas and complicated parapneumonic effusions. (
  • It can affect any age group, sex and ethnicity and over 65,000 patients suffer from a pleural infection each year in the UK and USA [ 7 ], with an estimated hospital cost of 500 million USD. (
  • The prevalence of HIV/AIDS, wider use of immunosuppressants and organ transplantation, and increasing age of the population mean pleural infection will continue to remain a common and significant illness. (
  • Pleural infection can also complicate thoracic (open or closed) trauma and iatrogenic procedures, such as surgery (especially lung resection) or oesophageal rupture. (
  • Despite numerous studies the best management of pleural infection remains controversial with widespread variations in practice [ 14 ]. (
  • This review will examine novel themes of translational research, highlighting areas of clinical importance and fields in need of further investigation, as well as evaluating the current best clinical management of pleural infection. (
  • Pleural infection remains difficult to treat in part, as the underlying disease mechanisms are poorly elucidated. (
  • Basic laboratory research in pleural infection is hampered by a lack of suitable in vivo models. (
  • Cases of pleural effusion which were not due to infection were excluded. (
  • The typical diagnostic signs and symptoms of empyema (lung infection) include fever, cough, and sputum discharge as well as the development of pleural effusion (causing chest pain and shortness of breath). (
  • Most empyemas develop from an underlying pulmonary infection and are thought to be secondary to subclinical aspiration of organisms in the dependent portions of the affected lung.15 Alcohol abuse is a recognized risk factor for pleural empyema, primarily because of the increased incidence of aspiration pneumonia. (
  • 18 Immunocompromised patients are prone to pleural involvement with fungal or aerobic gram-negative bacillary infection. (
  • Pleural infection was first described by Hippocrates in 500 BC [ 1 ]. (
  • Worldwide, the management of patients with pleural infection varies widely and approaches differ among physicians [ 2 ]. (
  • suggested that in treating pleural infection, smaller, guide wire inserted chest tubes caused substantially less pain than larger, blunt dissection-inserted tubes without impairing clinical outcomes [ 5 ]. (
  • managed by presentation, which may include immunosuppressive intercostal tube drainage (ICT) plus intrapleural states (most frequently HIV infection, diabetes instillation of streptokinase as fibrinolytic agent. (
  • Patients were included if they received IP t-PA and/or IP DNase for a pleural infection and were excluded if they received IP t-PA or IP DNase for chest tube clearance. (
  • To be included in the analysis, patients had to be ≥18 years of age and received at least one dose of IP t-PA and/or IP DNase for a pleural infection. (
  • Pleural tuberculosis (TB) is most often a side phenomenon of primary infection and seldom requires operative intervention except for diagnostic purposes. (
  • In a series of 380 empyema patients reported by Weissberg and Refaely (1996) , no case of fungal infection was mentioned. (
  • Once the pleural space has been cleaned, a complete and definitive obliteration of the space must be achieved to prevent further relapse of the infection. (
  • During reactivation of TB, pleural infection turns to a true empyema, characterized by an opaque and purulent effusion. (
  • Pleural infection, as noted by Weir and Thornton (1985) , is supposed to originate from subpleural pulmonary lesions. (
  • Parapneumonic effusion or empyema is a collection of fluid in the pleural space as a result of pneumonia. (
  • Symptoms often develop over several days and the effusion may not develop until after antibiotic treatment has been started for the pneumonia. (
  • These occur in up to 60% of patients with Streptococcus pneumoniae pneumonias, but can be seen with any pneumonia (usually bacterial, although viral and fungal infections can rarely produce effusions). (
  • Pneumonia (bacterial) without a pleural effusion - has a similar clinical presentation, but no effusion on CXR. (
  • Both S. pneumoniae and S. pyogenes are associated with complicated pneumonia although S. pneumoniae serotypes 3, 19A, and 7F account for the majority of infections. (
  • Frequently the pleural effusion develops after antibiotic therapy for bacterial pneumonia is started and may be related to rapid bacterial killing by the antibiotics. (
  • Infections of the pleural space most commonly follow pneumonia, accounting for 40 to 60% of all empyema. (
  • Since bacterial pneumonia is the most common predisposing factor for empyema, patients at risk for pneumonia are at risk for empyema. (
  • The aforementioned models differ from common clinical scenarios in that empyema is induced in the absence of concurrent pneumonia. (
  • Approximately 20 to 30 percent of patients with bacterial pneumonia develop a radiographically apparent pleural effusion. (
  • asserted that the need for pleural space drainage was due to clinical factors, including prolonged pneumonia symptoms, comorbidities, failure to respond to antibiotic therapy, and the presence of anaerobic organisms [ 4 ]. (
  • The Infectious Disease Society of America (IDSA) pediatric pneumonia guidelines from 2011 detail the management of parapneumonic effusions based on the size of the effusion and the degree of respiratory compromise. (
  • Vancomycin and ceftriaxone were initiated for presumed community-acquired pneumonia complicated by empyema. (
  • sometimes seen as a complication of empyema, fibrosis, or pneumonia. (
  • Malignant effusion - is a pleural effusion due to pleural infiltration of cancerous cells (usually lymphoma or leukemia) and is almost always distinguishable by history. (
  • Table 2 shows the most common causes of pleural effusion. (
  • Occlusion of chest tubes is one of the primary causes of pleural drain failure. (
  • For malignancy (cancer)-causing pleural effusion (fluid in the pleural space filled with malignant cells), the diagnosis can be established with positive cytopathology (cancer cell visualization and analysis) and a chest x ray that shows fluid accumulation. (
  • Tube thoracostomy is often the first step in the treatment of pneumothorax, hemothorax, hemopneumothorax, empyema, and pleural effusion. (
  • Primary spontaneous pneumothorax :Patients with underlying lung disease and traumatic pneumothoraces usually require chest drainage. (
  • Pleural effusion  Pleural fluid  Malignant pleural effusion  Simple pleural effusions in ventilated patients  Empyema and complicated parapneumonic pleural effusion  Traumatic pneumothorax or haemopneumothorax  Peri-operative eg. (
  • 1,3 Conditions that may necessitate the need for placement of a chest tube include pneumothorax, complicated parapneumonic effusions (ie, empyemas), and trauma or injury to the chest wall. (
  • In the fibrinopurulent stage, the deposition of fibrin on the parietal pleura retards the resorption of blood, preventing access to lymphatics and retarding fluid resorption.19 Fibrin deposition in the presence of bacteria provides an ideal environment for the development of pleural empyema. (
  • Patients who are symptomatic from a large, malignant pleural effusion may benefit from indwelling tunneled pleural catheters or effusion drainage followed by pleurodesis. (
  • Thoracotomy tubes, (more commonly known as chest tubes or pleural catheters) are used to drain unwanted air, fluid (blood, pus, chyle, and serous fluids), or blood clots from the pleural space (ie, the area between the chest wall and the lungs). (
  • Literature describing the use of alteplase to restore patency to occluded chest tubes and pleural catheters is sparse. (
  • SUMMARY: Increased understanding of the pathogenesis of empyema may ultimately yield novel therapeutic targets. (
  • To evaluate the efficacy and safety of intrapleural alteplase vs urokinase in patients with complex complicated parapneumonic pleural effusion and empyema during one year of follow-up. (
  • One commonly used method involves the intrapleural injection of turpentine, which results in pleural inflammation and an exudative effusion, prior to the introduction of pathogens [ 18 ]. (
  • it was to compare the therapeutic yield of medical thoracoscope and intrapleural fibrinolysis by streptokinase in complicated parapneumonic effusion and empyema. (

  • Alteplase is also used off-label for intrapleural administration in the management of parapneumonic effusion and empyema. (
  • Methods Used to Investigate Pleural Disease Medical History Patients with pleural effusions should be studied systematically. (
  • The objective of this study is to describe the practice of IP t-PA and IP DNase administration in patients with pleural infections at a tertiary academic medical center. (
  • 3,5,9 In a 2005 British Thoracic Society (BTS) guideline for the management of pleural infections in children, recommendations for unclogging blocked drains include flushing the drain with normal saline or allowing urokinase (a fibrinolytic not available in the US) to dwell in the catheter. (
  • Overall parapneumonic empyema hospitalization rates in the United States have increased across all age groups. (
  • 11 The stages of a parapneumonic empyema are exudative, fibrinopurulent, and organizing. (
  • The use of ultrasonography guided insertion is particularly useful for empyema and effusions as the diaphragm can be localised and the presence of loculations and pleural thickening defined. (
  • These other causes for pleural effusions are distinguished from parapneumonic effusion and empyema based on clinical history and physical findings. (
  • Most patients with empyema present with a clinical picture of cough, fever, purulent sputum, shortness of breath, and chest pain. (
  • To gather data on the clinical presentation of parapneumonic effusion and empyema and to examine the effect of different management strategies on short term outcomes. (
  • Other symptoms and signs of a parapneumonic effusion or empyema include: shortness of breath, generalized malaise, night sweats, weight loss, dullness to percussion of the chest, crackles, or rarely a friction rub. (
  • Pleural disease is most frequently encountered on chest radiography and CT, as these are routinely ordered in patients with signs and symptoms such as shortness of breath, cough, chest pain, or fever. (
  • There have been no systematic studies of diseases causing pleural effusion in Qatar. (
  • 9 Aside from these recommendations, other applicable guidelines for pleural diseases do not specify a preferred method for unclogging blocked pleural drains. (
  • Several studies have linked an increased incidence of S. aureus , S. pneumoniae , and S. pyogenes empyema associated with influenza. (
  • The incidence of empyema is rising in both developed and developing countries, including in paediatric populations. (
  • In Scotland, the incidence of empyema has risen 10 times in 1-4 yr old children since 1998 [ 8 ], with similar reports from the USA, Canada and elsewhere in Europe, and the trend is mirrored in adults [ 9 - 12 ]. (
  • P = 0.020) was significantly related to the incidence of adverse events during chest drainage. (
  • 4 The incidence of tube blockage varies widely in the literature, but rates up to 64% have been reported for patients with empyema. (
  • Empyema is a collection of pus between the lung and the chest wall (pleural space). (
  • Usually, the term refers to empyema thoracis which is the collection of pus in the pleural space. (
  • The potential space between the visceral and parietal pleura is the pleural space. (
  • Findings concerning for pleural malignancy include circumferential pleural thickening, nodular pleural thickening, parietal pleural thickening greater than 1 cm, and involvement of the mediastinal pleura. (
  • Introduction The pleural space, between the parietal pleura covering the chest wall and the visceral pleura covering the lung, contains in a healthy person a few milliliters of fluid that acts as a lubricant between the 2 surfaces. (
  • Over a period of 4 to 6 weeks after the start of an empyema, the fibrin layer becomes organized and forms a thick peel (the thickened pleura that develops around a pleural empyema) in the chronic organizing phase.16 Early management of empyema may prevent the progression of this process to the more advanced stages, where multiple loculations and scarring complicate drainage. (
  • 4 Pleural metastases may present as pleural effusions and should be included in the differential diagnosis of large, unilateral pleural effusions or loculated pleural effusions, especially in patients with a history of malignancy (Figure 1). (
  • In the presence of one or more of these findings, the sensitivity and specificity for pleural malignancy are 72% and 83%, respectively (Figure 2). (
  • In patients with a malignancy, fungal or tuberculous foci may be reactivated, and empyema develops. (
  • Thoracic empyema [] The thoracic empyema may have developed via a pulmonary fistula in this case. (
  • however, death from overwhelming sepsis frequently complicates this model unless systemic antibiotics are administered. (
  • Conclusion: The majority of patients at our institution received concomitant IP t-PA and IP DNase after systemic therapy for treatment of pleural infections had been attempted. (
  • The use of IP t-PA and IP DNase may be indicated after chest tube drainage and systemic antimicrobial therapy has been insufficient to manage pleural effusions. (
  • The oldest known reference to thoracic drainage dates back to the fifth century B.C.E. Hippocrates (c. 460-370 B.C) (3) was a pioneer of a rational view of disease, in which the four humors of the body - blood, phlegm, black bile, and yellow bile - must be in balance to preserve health (4). (

  • More recent guidelines for the management of empyema from the American Association for Thoracic Surgery similarly do not provide recommendations for the management of blocked pleural drains, but again recommend routine flushing as a preventative strategy. (
  • Computed axial tomography (CAT) scans can be used to visualize and analyze complicated cases that may require chest tube insertion. (
  • Patients with thoracic empyema occasionally require chest tubes for drainage. (
  • The drainage of a post pneumonectomy space should only be carried out by or after consultation with a cardiothoracic surgeon. (
  • 2002 Jan [PubMed] [] Enterococcus casseliflavus was detected in cultures for bacteria of the effusion from the empyema space. (
  • Pathological accumulation of fluid in this space is called pleural effusion. (
  • A chest tube insertion is a procedure to place a flexible, hollow drainage tube into the chest in order to remove an abnormal collection of air or fluid from the pleural space (located between the inner and outer lining of the lung). (
  • Chest tubes are used to treat conditions that can cause the lung to collapse, which occurs because blood or air in the pleural space can hamper the ability of a patient to breath. (
  • Pleural empyema represents a continuum of disease ranging from thin pleural fluid microscopically contaminated by organisms to gross pus in the pleural space. (
  • Mycobacterial and fungal infections of the pleural space are uncommon disorders in the Western world. (
  • The common feature of chronic mycobacterial and fungal infections is that often the underlying lung cannot be reexpanded to fill the pleural space, either because of previous partial resection or because of diffuse fibrosis. (
  • Despite advances in antimicrobial therapy and improved imaging, empyemas remain an important cause of morbidity and mortality. (
  • Delays in diagnosis, failure to start appropriate antimicrobial therapy, and inadequate drainage contribute to increased morbidity, mortality, and costs. (
  • The location where subdural empyema may appear is a challenge in diagnosis and treatment. (
  • Frontal and lateral chest radiographs are useful screening tools and can reveal many forms of pleural disease. (
  • Pleural metastatic disease indicates an advanced stage of cancer and generally a poor prognosis. (
  • 17 Klebsiella pneumoniae empyema may occur in alcoholic males with multiple host defense defects that impair containment of or perception of disease until it is well advanced. (

  • Revealing respiratory symptoms are nonproductive cough, pleuritic chest pain, and dyspnea correlated with the extent of effusion. (
  • The aim of this study was to investigate the outcomes of patients with empyema who underwent drainage using a smaller-size chest tube. (
  • Furthermore, outcomes of chest drainage are similar for tubes larger than and smaller than 20 Fr. (
  • 2 For drainage, both chest-tube with fibrinolytics and video-assisted thoracoscopy (VAT) have been shown to be effective. (
  • The British Thoracic Society (BTS) recommends prompt pleural drainage for patients with frankly purulent or turbid/cloudy pleural fluid on sampling [ 1 , 3 ]. (
  • Both the IDSA and the American Pediatric Surgery Association guidelines recommend drainage for moderate parapneumonic effusions associated with respiratory distress, large parapneumonic effusions, or documented purulent effusions. (
  • The gamut runs from a thin idiopathic effusion that may yield acid-fast bacilli with difficulty, if at all, to a thick purulent exudate that has positive results on direct smears. (
  • In the early phase, the effusion is thin, watery, and easily drained by thoracostomy. (
  • When there is a doubt in the case of small effusions the existence of pleural fluid should be confirmed by chest ultrasound or radiographically using a lateral decubitus projection on the affected side. (
  • The optimal management of parapneumonic effusions and empyema in children remains controversial and currently there is insufficient evidence to give clear guidance on therapy. (
  • Administration of IP t-PA and IP DNase demonstrated improved drainage of pleural infections with minimal harm to patients. (
  • However, limited data exist describing the prescribing practices of IP t-PA and IP DNase for pleural infections, including the procedures for preparing and administering these products. (
  • The stage of effusion was not associated with duration of previous symptoms or length of previous admission. (
  • In the case of small effusions, thoracentesis can be undertaken if the distance between the horizontal line of the pleural effusion and the chest wall is more than 1 cm on an ipsilateral decubitus view. (
  • The role of thoracic ultrasound in guiding investigation and drainage of empyema is clear. (
  • Effusions were classified into three stages dependent on ultrasound findings. (
  • Standard chest tubes (26-32 Fr) are often placed without ultrasound or CT guidance by thoracic surgeons for treating complicated parapneumonic effusion and empyema [ 6 ]. (
  • Histological examination and culture of pleural biopsy were the most useful diagnostic workup for tuberculosis effusions, whereas repeated cytological examination of pleural fluid and pleural biopsy were most useful for malignant effusions. (
  • If a pleural biopsy is needed for diagnosis, positron emission tomography (PET) imaging or contrast-enhanced CT (CECT) may elucidate optimal targets for tissue sampling. (
  • During the influenza pandemic of 1917-1919, closed pleural drainage became widely practiced to treat post-pneumonic empyema [ 1 ]. (
  • [] K. pneumoniae was the most frequent cause of community-acquired thoracic empyema or complicated parapneumonic effusion. (
  • patients with parapneumonic effusion and empyema must be managed probably to avoid surgery and decortication, the use of medical thoracoscope and instillation of streptokinase intra pleural through intercostal tube consider a modality of dealing with that medical situation. (
  • 5 , 6 Because the evidence is not clear, the IDSA guidelines currently suggest that choice of drainage modality be based on local expertise. (
