Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Gas Embolism With Use of Argon Plasma Coagulation

Further study details as provided by Beth Israel Deaconess Medical Center:

Primary Outcome Measures:
  • incidence of gas bubbles with use of APC [ Time Frame: end of procedure ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 75
Study Start Date: July 2008
Estimated Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Detailed Description:
Gas embolism is a rare but serious complication of APC. We will use TEE to monitor for gas bubbles during APC. APC will be terminated if gas bubbles are associated with ischemic heart rhythms, wall motion abnormalities, or if large gas bubbles are noted in the left ventricle.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
patients referred to tertiary care center

Inclusion Criteria:

  • Adults (male and female) 18 years of age or older
  • Clinical indication for bronchoscopy (hemoptysis, airway obstruction, tumor excision, granulation tissue that is impairing endobronchial stent performance)
  • Ability of the patient or proxy to read, comprehend, and sign informed consent document.

Exclusion Criteria:

  • Presence of esophageal disorders that may complicate transesophageal echocardiography (strictures, varices, fistula, prior esophageal surgery)
  • Presence of coagulopathy or other bleeding diathesis
  • Inability to tolerate brief periods of apnea
  • Presence of pulmonary vascular disease
  • Pregnant women will not be included in this study because the potential fetal hypoxemia is not an acceptable risk.
  • No exclusions will be made based on gender or race.
