Improved heart hemodynamics after draining large-volume pleural effusion: a prospective cohort study.

ABSTRACT: BACKGROUND:Pleural effusion (PE) drainage can relieve the symptoms of dyspnea; however, details of the resulting hemodynamic changes remain undefined. METHODS:Subjects older than 12 years with massive PE requiring pleural drainage were included in this study. Hemodynamic parameters were collected using transthoracic echocardiography at pre-drainage, immediately post-drainage, and 24 h after drainage. RESULTS:We enrolled 47subjects in this prospective study from June 9, 2015 to September 18, 2016 in Beijing Chaoyang Hospital and 28 subjects were analyzed finally. Draining large-volume PE led to a progressive increase in left ventricular end-diastolic volume index, left atrial volume index, right ventricular area, right atrial area, left ventricular ejection fraction, stroke volume, and tricuspid annular plane systolic excursion, both immediately (P?< 0.05) and 24 h after drainage (P?< 0.05). The cardiac diastolic measurement ratios of early-transmitral flow velocity to diastolic mitral annular velocity and myocardial performance index decreased significantly following drainage (P?< 0.05). More parameters were influenced by left-sided PE drainage. The correlation between effusion volume and changes in echocardiographic measurements was not statistically significant. CONCLUSIONS:Improved preload, and systolic and diastolic function is pivotal for hemodynamic change after draining large PE volumes. Subjects experienced improved cardiac hemodynamics following PE drainage, underlining the beneficial therapeutic and subjective effects.

Project description:ObjectivesThe prevalence and optimal management of clinically significant pleural effusion, confirmed by thoracic ultrasound, in the critically ill is unknown. This study aimed to determine: 1) the prevalence, characteristics, and outcomes of patients treated in intensive care with clinically significant effusion and 2) the comparative efficacy and safety of pleural drainage or expectant medical management.DesignA prospective multicenter cohort study.SettingICUs in four teaching hospitals in Western Australia.PatientsConsecutive patients with clinically significant pleural effusions (depth ≥ 2 cm on thoracic ultrasound with clinician-determined adverse effects on patient progress).InterventionsNone.Measurements and main resultsPrimary outcome was the change in Pao2:Fio2 (mm Hg) ratio from baseline to 24 hours. Changes in diagnosis and treatment based on pleural fluid analysis and pleural effusion related serious adverse events between those who underwent either drainage within 24 hours or expectant management were compared. Of the 7,342 patients screened, 226 patients (3.1%) with 300 pleural effusions were enrolled. Early drainage of pleural effusion occurred in 76 patients (34%) and significantly improved oxygenation (Pao2:Fio2 ratio 203 at baseline vs 263 at 24 hr, +29.6% increment; p < 0.01). This was not observed in the other 150 patients who had expectant management (Pao2:Fio2 ratio 250 at baseline vs 268 at 24 hr, +7.2% increment; p = 0.44). The improvement in oxygenation after early drainage remained unchanged after adjustment for a propensity score on the decision to initiate early drainage. Pleural effusion related serious adverse events were not different between the two groups (early drainage 10.5% vs no early drainage 16.0%; p = 0.32). Improvements in diagnosis were noted in 91 initial (nonrepetitive) drainages (76.5% out of 119); treatment strategy was optimized after 80 drainage episodes (59.7% out of 134).ConclusionsEarly drainage of clinically significant pleural effusion was associated with improved oxygenation and diagnostic accuracy without increased complications.

Project description:BACKGROUND:Prolonged air leak and high-volume pleural drainage are the most common causes for delays in chest tube removal following lung resection. While digital pleural drainage systems have been successfully used in the management of post-operative air leak, their effect on pleural drainage and inflammation has not been studied before. We hypothesized that digital drainage systems (as compared to traditional analog continuous suction), using intermittent balanced suction, are associated with decreased pleural inflammation and postoperative drainage volumes, thus leading to earlier chest tube removal. METHODS:One hundred and three [103] patients were enrolled and randomized to either analog (n=50) or digital (n=53) drainage systems following oncologic lung resection. Chest tubes were removed according to standardized, pre-defined protocol. Inflammatory mediators [interleukin-1B (IL-1B), 6, 8, tumour necrosis factor-alpha (TNF-?)] in pleural fluid and serum were measured and analysed. The primary outcome of interest was the difference in total volume of postoperative fluid drainage. Secondary outcome measures included duration of chest tube in-situ, prolonged air-leak incidence, length of hospital stay and the correlation between pleural effusion formation, degree of inflammation and type of drainage system used. RESULTS:There was no significant difference in total amount of fluid drained or length of hospital stay between the two groups. A trend for shorter chest tube duration was found with the digital system when compared to the analog (P=0.055). Comparison of inflammatory mediator levels revealed no significant differences between digital and analog drainage systems. The incidence of prolonged post-operative air leak was significantly higher when using the analog system (9 versus 2 patients; P=0.025). Lobectomy was associated with longer chest tube duration (P=0.001) and increased fluid drainage when compared to sub-lobar resection (P<0.001), regardless of drainage system. CONCLUSIONS:Use of post-lung resection digital drainage does not appear to decrease pleural fluid formation, but is associated with decreased prolonged air leaks. Total pleural effusion volumes did not differ with the type of drainage system used. These findings support previously established benefits of the digital system in decreasing prolonged air leaks, but the advantages do not appear to extend to decreased pleural fluid formation.
