External Drainage of Thoracic Duct Lymph to Reduce Inflammatory Cytokines in Septic Shock Patients: A Pilot Trial With Concurrent Controls to Confirm Safety and Assess Preliminary Efficacy
University of Pennsylvania
Summary
To demonstrate that external drainage of thoracic duct lymph during sepsis results in a reduction in circulating pro-inflammatory cytokines. To demonstrate safety and feasibility of early thoracic duct cannulation and external lymph drainage for up to 7 days in adult surgical intensive care patients. To explore other biochemical and physiological endpoints that can be used for the design of future randomized controlled trials and estimate effect size of external drainage.
Description
This is an interventional cohort study that will involve external drainage of thoracic duct lymph in Surgical ICU patients with septic shock. The lymph drainage will continue for up to a maximum of 7 days and will be continued in those interventional group patients discharged from ICU back to the ward before that time. The lymph (and time-matched blood) will be periodically sampled to detect changes in composition which will be correlated with changes in disease severity and outcomes, as well as patient physiology and biochemistry. This pilot study is not powered to detect changes in hospital/…

Inclusion Criteria: * Adult (18-80 years) patients in Surgical ICU with suspected or documented infection on antibiotics and septic shock defined as hypotension requiring vasopressor therapy to maintain MAP \> 65mmHg (modified from Sepsis-35). Participants will fulfill the inclusion criteria not only at recruitment and consent, but also be confirmed to still meet those criteria immediately prior to transfer to IR for the procedure. The patient will not be recruited if he or she no longer meet these criteria. Patients experiencing hemodynamic instability, defined as (1) MAPs \< 65 despite o…
