“…Several simple equations have been devised to try and estimate fluid volume based on ultrasound appearances. HASSAN et al [69] tested the accuracy of five of these in 46 patients, and determined the most accurate to involve the total height of the effusion (H) in cm and the distance from bottom of the lung to apex of the diaphragm (C) in cm:…”

Thoracic ultrasound is increasingly considered to be an essential tool for the pulmonologist. It is used in diverse clinical scenarios, including as an adjunct to clinical decision making for diagnosis, a real-time guide to procedures, and a predictor or measurement of treatment response. The aim of this European Respiratory Society task force was to produce a statement on thoracic ultrasound for pulmonologists using thoracic ultrasound within the field of respiratory medicine. The multidisciplinary panel performed a review of the literature, addressing major areas of thoracic ultrasound practice and application. The selected major areas include equipment and technique, assessment of the chest wall, parietal pleura, pleural effusion, pneumothorax, interstitial syndrome, lung consolidation, diaphragm assessment, intervention guidance, training, and the patient perspective. Despite the growing evidence supporting the use of thoracic ultrasound, the published literature still contains a paucity of data in some important fields. Key research questions for each of the major areas were identified, which serve to facilitate future multi-centre collaborations and research to further consolidate an evidence-based use of thoracic ultrasound, for the benefit of the many patients being exposed to clinicians using thoracic ultrasound.

“…The size of the effusion should be noted. Semi-quantitative methods measuring the depth of the effusion and its height in rib spaces usually suffice, but various methods exist for more accurate calculations [6]. The echogenicity (brightness) of the effusion should also be noted, as it gives an indication to its aetiology (figure 3a and b).…”

Physician-led thoracic ultrasound (TUS) has substantially changed how respiratory disorders, and in particular pleural diseases, are managed. The use of TUS as a point-of-care test enables the respiratory physician to quickly and accurately diagnose pleural pathology and ensure safe access to the pleural space during thoracentesis or chest drain insertion. Competence in performing TUS is now an obligatory part of respiratory speciality training programmes in different parts of the world. Pleural physicians with higher levels of competence routinely use TUS during the planning and execution of more sophisticated diagnostic and therapeutic interventions, such as core needle pleural biopsies, image-guided drain insertion and medical thoracoscopy. Current research is gauging the potential of TUS in predicting the outcome of different pleural interventions and how it can aid in tailoring the optimum treatment according to different TUS-based parameters.

“…In this formula, the maximal craniocaudal distance of effusion in centimeters is added to the height of the subpulmonal effusion and multiplied by factor 70, resulting in the anticipated volume of pleural effusion in milliliters, having the highest reported accuracy. Few other equations were later proposed, but with a lower accuracy [ 33 ]. According to the Goecke and Schwerk equation, and using our threshold, the decision on pleural drainage procedure should be carefully considered if the sum of craniocaudal and subpulmonal distances is less than 14 cm (14 × 70 = 980 mL).…”

Pleural effusions are a common finding in critically ill patients and small bore chest drains (SBCD) are proven to be efficient for pleural drainage. The data on the potential benefits and risks of drainage remains controversial. We aimed to determine the cut-off volume for complications, to investigate the impact of pleural drainage and drained volume on clinically relevant outcomes. Medical records of all critically ill patients undergoing insertion of SBCD were retrospectively examined. We screened 13,003 chest radiographs and included 396 SBCD cases in the final analysis. SBCD drained on average 900 mL, with less amount in patients with complications (p = 0.003). A drainage volume of 975 mL in 24 h represented the optimal threshold for complications. Pneumothorax was the most frequent complication (4.5%), followed by bleeding (0.8%). Female and lighter-weighted patients experienced a higher risk for any complication. We observed an improvement in the arterial partial pressure of oxygen and respiratory quotient (p < 0.001). We conclude that the small drainage volumes are associated with complications in critically ill patients—the more you drain, the safer the procedure gets. The use of SBCD is a safe and efficient procedure, further investigations regarding the higher rate of complications in female and lighter-weighted patients are desirable.

Validation of equations for pleural effusion volume estimation by ultrasonography

Abstract: Pleural effusion height measured by ultrasonography gives a reasonable estimate of effusion volume. Incorporating distance between lung base and diaphragm into estimation improves accuracy from 79% with the first method to 83% with the latter.
