Chest Tubes and Pleural Drainage: History and Current Status in Pleural Disease Management.

Thoracostomy and chest tube placement are key procedures in treating pleural diseases involving the accumulation of fluids (e.g., malignant effusions, serous fluid, pus, or blood) or air (pneumothorax) in the pleural cavity. Initially described by Hippocrates and refined through the centuries, chest drainage achieved a historical milestone in the 19th century with the creation of closed drainage systems to prevent the entry of air into the pleural space and reduce infection risk. The introduction of plastic materials and the Heimlich valve further revolutionized chest tube design and function. Technological advancements led to the availability of various chest tube designs (straight, angled, and pig-tail) and drainage systems, including PVC and silicone tubes with radiopaque stripes for better radiological visualization. Modern chest drainage units can incorporate smart digital systems that monitor and graphically report pleural pressure and evacuated fluid/air, improving patient outcomes. Suction application via wall systems or portable digital devices enhances drainage efficacy, although careful regulation is needed to avoid complications such as re-expansion pulmonary edema or prolonged air leak. To prevent recurrent effusion, particularly due to malignancy, pleurodesis agents can be applied through the chest tube. In cases of non-expandable lung, maintaining a long-term chest drain may be the most appropriate approach and procedures such as the placement of an indwelling pleural catheter can significantly improve quality of life. Continued innovations and rigorous training ensure that chest tube insertion remains a cornerstone of effective pleural disease management. This review provides a comprehensive overview of the historical evolution and modern advancements in pleural drainage. By addressing both current technologies and procedural outcomes, it serves as a valuable resource for healthcare professionals aiming to optimize pleural disease management and patient care.

Chest tube size selection for pleural effusion: from the perspective of thoracic surgeons and pulmonologists

ABSTRACT Background The current discourse within the thoracic surgical and pulmonological communities pertains to a contentious debate over the optimal selection criteria for thoracostomy tube diameters utilized in the management of pleural effusions. A comprehensive examination of the variables that inform the clinical decision-making paradigm for the determination of appropriate chest tube calibers is imperative to enhance patient management and elevate the prognostic results. Objectives The objective of this inquiry is to elucidate the determinants that influence thoracic surgeons and pulmonologists in their selection of chest tube size for the management of pleural effusions. Methods This cross-sectional study was based on an electronic questionnaire that was sent to the targeted populations through e-mail or a professional WhatsApp. The survey assessed the considerations of chest tube size selection as well as the respective advantages, disadvantages, and potential complications related to each size. Results The conducted study encompassed participants, with a nearly even distribution between thoracic surgeons (49.1%) and pulmonologists (50.9%). Most of these practitioners are within tertiary-level medical institutions (82.1%). A preference for small-bore chest tubes (SBCT), defined as < 14 French (Fr), was indicated by 54.8% of participants. The drawbacks associated with SBCT, such as kinking (60%) and blockage (70%), influenced the decision-making process negatively, while pain was a significant factor in the selection against LBCT (64%). Ultrasound guidance was a positive influence for the selection of SBCT (55%). Complications associated with LBCT included visceral and vascular injuries (55.7%), wound infection (45.3%), re-expansion pulmonary edema (43.3%), and subcutaneous emphysema (57.5%). In contrast, malposition was a complication more commonly associated with SBCT (49.1%). Conclusion The decision regarding chest tube size was influenced by several critical factors which included the nature of pleural effusion, the volume of pleural fluid, and potential complications specific to the size of the chest tube used.

Gravity- vs Wall Suction-Driven Large-Volume Thoracentesis: A Randomized Controlled Study

Prior studies have found no differences in procedural chest discomfort for patients undergoing manual syringe aspiration or drainage with gravity after thoracentesis. However, whether gravity drainage could protect against chest pain due to the larger negative-pressure gradient generated by wall suction has not been investigated. Does wall suction drainage result in more chest discomfort compared with gravity drainage in patients undergoing large-volume thoracentesis? In this multicenter, single-blinded, randomized controlled trial, patients with large free-flowing effusions of≥ 500mL were assigned at a 1:1 ratio to wall suction or gravity drainage. Wall suction was performed with a suction system attached to the suction tubing and with vacuum pressure adjusted to full vacuum. Gravity drainage was performed with a drainage bag placed 100cm below the catheter insertion site and connected via straight tubing. Patients rated chest discomfort on a 100-mm visual analog scale before, during, and after drainage. The primary outcome was postprocedural chest discomfort at 5 min. Secondary outcomes included measures of postprocedure chest discomfort, breathlessness, procedure time, volume of fluid drained, and complication rates. Of the 228 patients initially randomized, 221 were included in the final analysis. The primary outcome of procedural chest discomfort did not differ significantly between the groups (P= .08), nor did the secondary outcomes of postprocedural discomfort and dyspnea. Similar volumes were drained in both groups, but the procedure duration was longer in the gravity arm by approximately 3 min. No differences in rate of pneumothorax or reexpansion pulmonary edema were noted between the two groups. Thoracentesis via wall suction and gravity drainage results in similar levels of procedural discomfort and dyspnea improvement. ClinicalTrials.gov; No.: NCT05131945; URL: www. gov.

Re-expansion Pulmonary Edema (REPE) Following Thoracentesis: Is Large-Volume Thoracentesis Associated with Increased Incidence of REPE?

To determine the safety and efficacy associated with drainage volumes greater than 1,500mL in a single, unilateral thoracentesis without pleural manometry measurements. This retrospective, single-institution study included 872 patients (18years and older) who underwent ultrasound-guided thoracentesis. Patient and procedures data were collected including demographics, number of and laterality of thoracenteses, volume and consistency of fluid removed, and whether clinical or radiologic evidence of re-expansion pulmonary edema (REPE) developed within 24h of thoracentesis. Fisher's exact test was used to test the significance of the relationship between volume of fluid removed and evidence of REPE. A total of 1376 thoracenteses were performed among the patients included in the study. The mean volume of fluid removed among all procedures was 901.1mL (SD = 641.7mL), with 194 (14.1%) procedures involving the removal of ≥ 1,500mL of fluid. In total, six (0.7%) patients developed signs of REPE following thoracentesis, five of which were a first-time thoracentesis. No statistically significant difference in incidence of REPE was observed between those with ≥ 1,500mL of fluid removed compared to those with < 1,500mL of fluid removed (p-value = 0.599). Large-volume thoracentesis may safely improve patients' symptoms while preventing the need for repeat procedures.

Re-Expansion Pulmonary Edema as a Life-Threatening Complication in Massive, Long-Standing Pneumothorax: A Case Series and Literature Review.

Re-expansion pulmonary edema is a rare and potentially life-threatening complication that can occur after the rapid re-expansion of a collapsed lung due to pneumothorax or pleural effusion. It has a multifactorial pathogenesis, and risk factors for re-expansion pulmonary edema, such as chronic lung collapse, rapid re-expansion, and changes in pulmonary vascular permeability, have been identified. Clinical manifestations vary, ranging from almost asymptomatic to a rapidly fatal condition, and its incidence may be more common and less fatal than previously believed. The literature emphasizes the importance of early recognition and management to ensure favorable outcomes. However, there is ongoing debate regarding the indications for ventilatory support and the timing of non-invasive or invasive ventilation. Herein, we report a case series of three paradigmatic examples of massive re-expansion pulmonary edema occurring over a period of 10 years in our institution among a population of 815 patients with spontaneous pneumothorax. We also conducted a literature review on re-expansion pulmonary edema, with a particular focus on diagnosis and management. In each case, despite initially normal clinical parameters, severe respiratory distress developed following the insertion of a thoracic drainage tube for a massive spontaneous pneumothorax. Two patients required High-Flow Nasal Oxygen, and one was addressed to intensive management, including CPAP. In all cases, the patient's outcome was optimal.

Risk factors for re-expansion pulmonary edema following chest tube drainage in patients with spontaneous pneumothorax: A systematic review and meta-analysis.

Re-expansion pulmonary edema (RPE) is a rare but potentially life-threatening complication that can occur after rapid lung expansion following the management of lung collapse. This meta-analysis aimed to investigate the risk factors for RPE following chest tube drainage in patients with spontaneous pneumothorax. We conducted a comprehensive systematic literature search in electronic databases of PubMed, ScienceDirect, Cochrane Library, and ProQuest to identify studies that explore the risk factors for RPE following chest tube drainage in spontaneous pneumothorax. Pooled odds ratios (OR) or weighted mean differences (WMD) were calculated to evaluate the risk factors. Statistical analysis was conducted using Review Manager 5.3 software. Five studies involving 1.093 spontaneous pneumothorax patients were included in this meta-analysis. The pooled analysis showed that the following risk factors were significantly associated with increased risk of RPE following chest tube drainage: the presence smoking history (OR=1.94, 95% CI: 1.22-3.10, P=0.005, I2=0%), longer duration of symptoms (WMD=3.76, 95% CI: 2.07-5.45, P<0.0001, I2=30%), and larger size of pneumothorax (WMD=16.76, 95% CI: 8.88-24.64, P<0.0001, I2=78%). Age, sex, and location of pneumothorax had no significant association. In patients with spontaneous pneumothorax, the presence of smoking history, longer duration of symptoms, and larger size of pneumothorax increase the risk of development of RPE following chest tube drainage.

Anaesthesia Management for Giant Intraabdominal Tumours: A Case Series Study.

Due to a lack of randomised controlled trials and guidelines, and only case reports being available in the literature, there is no consensus on how to approach anaesthetic management in patients with giant intraabdominal tumours. This study aimed to evaluate the literature and explore the current status of evidence, by undertaking an observational research design with a descriptive account of characteristics observed in a case series referring to patients with giant intraabdominal tumours who underwent anaesthesia. Twenty patients diagnosed with giant intraabdominal tumours were included in the study, most of them women, with the overall pathology being ovarian-related and sarcomas. Most of the patients were unable to lie supine and assumed a lateral decubitus position. Pulmonary function tests, chest X-rays, and thoracoabdominal CT were the most often performed preoperative evaluation methods, with the overall findings that there was no atelectasis or pleural effusion present, but there was bilateral diaphragm elevation. The removal of the intraabdominal tumour was performed under general anaesthesia in all cases. Awake fiberoptic intubation or awake videolaryngoscopy was performed in five cases, while the rest were performed with general anaesthesia with rapid sequence induction. Only one patient was ventilated with pressure support ventilation while maintaining spontaneous ventilation, while the rest were ventilated with controlled ventilation. Hypoxemia was the most reported respiratory complication during surgery. In more than 50% of cases, there was hypotension present during surgery, especially after the induction of anaesthesia and after tumour removal, which required vasopressor support. Most cases involved blood loss with subsequent transfusion requirements. The removal of the tumor requires prolonged surgical and anaesthesia times. Fluid drainage from cystic tumour ranged from 15.7 L to 107 L, with a fluid extraction rate of 0.5-2.5 L/min, and there was no re-expansion pulmonary oedema reported. Following surgery, all the patients required intensive care unit admission. One patient died during hospitalization. This study contributes to the creation of a certain standard of care when dealing with patients presenting with giant intraabdominal tumour. More research is needed to define the proper way to administer anaesthesia and create practice guidelines.

Reexpansion pulmonary edema after treatment of primary spontaneous pneumothorax.

A 24-year-old male patient, without further symptoms or comorbidities presented to the emergency room with acute dyspnea after heavy lifting two days before. On auscultation an attenuated vesicular breath was noticed on the right lung. In the initial chest radiograph a right-sided primary spontaneous pneumothorax with minor mediastinal shift was diagnosed. After insertion of a 12-French chest tube the patient's clinical condition deteriorated. The following chest radiograph and computed tomography of the thorax showed a reexpansion pulmonary edema in the right lung. The patient was admitted to the ICU and supportive treatment was initiated. Pulmonary reexpansion edema after drainage of a pneumothorax is a very rare complication with mortality rates reaching up to 20%. The exact pathophysiology remains unknown. Typical Symptoms include dyspnea, hypotension, and tachycardia. To minimize the risk of a pulmonary reexpansion edema, not more than 1200-1800 ml of air should be drained at once and the drainage should be stopped when the patient starts coughing.

Pulmonary edema ex vacuo after drainage of pyo-pneumothorax

This case presents a rare occurrence of re-expansion pulmonary edema following a drainage of pyo-pneumothorax in a 33-year-old patient. The diagnosis was established through a thoracic radiography, and the treatment consisted of symptomatic management, showing positive progress. Later on, the patient was diagnosed with pleural tuberculosis via GeneXpert testing and subsequently initiated on anti-bacterial therapy.This case report aims to shed light on the infrequent pulmonary edema ex vacuo as a complication of pleural drainage. It explores its causes, risk factors, diagnostic approaches, and treatment options. this study highlights the necessity of effective prevention and management strategies.

Re-expansion Pulmonary Edema

Re-expansion pulmonary edema (RPE) is a rare complication of pleural puncture (thoracentesis) and chest tube insertion. The incidence of RPE is low (1%), but mortality can be up to 20%. The main pathophysiological mechanism is pulmonary edema due to increased permeability and increased hydrostatic pressure in the pulmonary capillaries. Risk factors include duration of lung collapse (&gt;3 to 7 days), size of pneumothorax (&gt;30%), volume of aspirated air or fluid (&gt;1.5 to 3 L), excessive negative intrapleural pressure, diabetes mellitus, and chronic hypoxemia. Prevention includes limiting the volume of aspirated air or fluid (&lt;1.5 L), air or fluid evacuation in a controlled manner, and preventing excessive negative intrapleural pressure. Treatment is supportive care through cardiovascular and respiratory monitoring, oxygen and decubitus positioning.

Unusual severe hypoxemia due to unilateral pulmonary edema after conventional cardiopulmonary bypass salvaged by veno-venous extracorporeal membrane oxygenation: a case report

BackgroundWe report a case in which veno-venous extracorporeal membrane oxygenation (V-V ECMO) saved the life of a patient who developed severe hypoxemia due to unusual unilateral pulmonary edema (UPE) after cardiopulmonary bypass (CPB).Case presentationA 69-year-old man underwent aortic valve replacement and coronary artery bypass grafting. Following uneventful weaning off CPB, he developed severe hypoxemia. The ratio of arterial oxygen tension to inspired oxygen fraction (PaO2/FiO2) decreased from 301 mmHg 5 min after CPB to 42 mmHg 90 min after CPB. A chest X-ray revealed right-sided UPE. Immediately established V-V ECMO increased PaO2/FiO2 to 170 mmHg. Re-expansion pulmonary edema (REPE) was likely, as the right lung remained collapsed during CPB following the accidental opening of the right chest cavity during graft harvesting.ConclusionsV-V ECMO was effective in improving oxygenation and saving the life of a patient who had fallen into unilateral REPE unusually developing after conventional CPB.

Re-expansion Pulmonary Edema: A Rare Complication of Chest Drain Insertion in Spontaneous Pneumothorax.

Re-expansion pulmonary edema (RPE) after chest drain insertion is rare. The objective of this clinical case report is to highlight the importance of this chest drain insertion complication. A 35-year-old man presented to the emergency department with a chief complaint of shortness of breath and pleuritic chest pain. Further physical examination and radiographic investigations showed a left-sided hemipneumothorax. A chest drain was inserted, but subsequently the patient developed worsening shortness of breath, desaturation, and coughed out pink frothy sputum. Repeated chest radiographic and computed tomographic thorax findings suggested RPE. A nonrebreathable mask with high-flow oxygen was given to the patient to maintain his oxygen saturation. The patient was referred to the cardiothoracic team and was admitted to the hospital. Despite conservative management in the ward, the patient underwent lung decortication. Postdecortication, the left-sided lung re-expanded well, and the patient was discharged home. This case highlighted this rare, potentially fatal complication of chest drain insertion for spontaneous pneumothorax.

HRCT Chest Findings of Re-expansion Pulmonary Edema: A Case Report

Re-expansion pulmonary edema occurs when the lung re-expands after an extended duration of collapse. It is rare with the reported incidence between 0% and 1%. We present a case of a 51-year male who presented with breathlessness, cough and right-sided chest pain. Chest radiograph showed right-sided pneumothorax. After 2 hours of chest tube insertion, the patient developed tachypnea and severe hypoxemia. HRCT chest revealed consolidation, ground glass opacity and smooth interlobular septal thickening in the right lung as well as a small patch of ground glass opacity in the contralateral lung. The serial radiograph showed resolution of consolidation and ground glass opacities.

Reexpansion Pulmonary Edema After Intrapleural Fibrinolytic Therapy

We report an empyema treated with antimicrobial therapy that developed reexpansion pulmonary edema after intrapleural fibrinolytic and enzyme therapy. Rapid evacuation of pleural fluid likely contributed to the development of reexpansion pulmonary edema.

Pleural manometry during thoracocentesis in patients with malignant pleural effusion: A randomized controlled trial.

Large-volume therapeutic thoracocentesis may be associated with pulmonary congestion or a more serious complication; re-expansion pulmonary edema (RPE). We investigated whether monitoring pleural pressure with manometry during thoracocentesis would prevent these pulmonary symptoms/RPE and allow larger volume drainage. We did a randomized controlled trial involving 110 patients with large malignant pleural effusions. Patients were randomly allocated to obtain thoracocentesis with or without pleural manometry. We measured the incidence of pulmonary congestion symptoms, total fluid aspirated, and pleural pressures in both groups. This trial is listed on ClinicalTrials.gov as NCT04420663. The mean amount of total thoracocentesis fluid withdrawn from the control group was 945.4±78.9 (mL) and 1690.9±681.0 (mL) from the intervention group (P<0.001). Clinical symptoms of pulmonary congestion appeared in (n=20) (36.3%) of patients in the intervention group while no symptoms appeared in controls (P<0.001). The difference between opening and closing pressures between the non-symptomatic cluster and the symptomatic cluster was (32.8±15.6 versus 42.2±13) respectively (P=0.02). Total fluid withdrawn from the non-symptomatic cluster was 1828.5±505 mL in comparison to 1,450±875 mL in the symptomatic cluster (P=0.04). Pleural manometry can be used to increase the volume of fluid removed on each occasion in patients with malignant pleural effusion. In our study, pleural manometry was associated with a larger number of pulmonary congestion symptoms/RPE. We believe that manometry may be a useful tool to not exceed a 17 cm H2O gradient in pleural pressure which should be avoided to prevent pulmonary congestion symptoms or RPE. Pulmonary congestion symptoms/RPE are not related to the amount of volume withdrawn but to the gradient of pleural pressure drop. Our conclusion does support the adoption of pleural manometry whenever large-volume thoracocentesis is intended.
