Consider using ultrasound to guide your puncture site.  In those cases where a puncture site was proposed clinically, 1\/4 of them were deemed dangerous and inaccurate.  Ultrasound was able to demonstrate a safe site in half of the cases when clinical exam did not yield a site.  (Chest 2003, 123:436-441)<\/p>\n

<\/span>Ultrasound-guided Thoracentesis<\/span><\/h2>\n

is it a safer method? Jones PW, Moyers JP, Rogers JT, Rodriguez RM, Lee YC, Light RW. Saint Thomas Hospital, and Vanderbilt University, Nashville, TN 37205, USA. STUDY OBJECTIVES: The objectives of this study are as follows: (1) to determine the incidence of complications from thoracentesis performed under ultrasound guidance by interventional radiologists in a tertiary referral teaching hospital; (2) to evaluate the incidence of vasovagal events without the use of atropine prior to thoracentesis; and (3) to evaluate patient or radiographic factors that may contribute to, or be predictive of, the development of re-expansion pulmonary edema after ultrasound-guided thoracentesis<\/strong>. DESIGN: Prospective descriptive study. SETTING: Saint Thomas Hospital, a tertiary referral teaching hospital in Nashville, TN.  PATIENTS: All patients referred to interventional radiology for diagnostic and\/or therapeutic ultrasound-guided thoracentesis between August 1997 and September 2000. RESULTS: A total of 941 thoracenteses in 605 patients<\/strong> were performed during the study period.  The following complications were recorded: pain (n = 25; 2.7%), pneumothorax (n = 24; 2.5%), shortness of breath (n = 9; 1.0%), cough (n = 8; 0.8%), vasovagal reaction (n = 6; 0.6%), bleeding (n = 2; 0.2%), hematoma (n = 2; 0.2%), and re-expansion pulmonary edema (n = 2; 0.2%).<\/strong>  Eight patients with pneumothorax received tube thoracostomies (0.8%).  When > 1,100 mL of fluid were removed, the incidence of pneumothorax requiring tube thoracostomy and pain was increased (p < 0.05).  Fifty-seven percent of patients with shortness of breath during the procedure were noted to have pneumothorax on postprocedure radiographs, while 16% of patients with pain were noted to have pneumothorax on postprocedure radiographs.  Vasovagal reactions occurred in 0.6% despite no administration of prophylactic atropine.   Re-expansion pulmonary edema complicated 2 of 373 thoracenteses (0.5%) in which > 1,000 mL of pleural fluid were removed.<\/strong> CONCLUSIONS: The complication rate with thoracentesis performed by interventional radiologists under ultrasound guidance is lower than that reported for non-image-guided thoracentesis.  Premedication with atropine is unnecessary given the low incidence of vasovagal reactions.  Re-expansion pulmonary edema is uncommon even when > 1,000 mL of pleural fluid are removed, as long as the procedure is stopped when symptoms develop.<\/strong>Joe Lex, MD, FAAEM Department of Emergency Medicine 1009 Jones Hall \u2013 Broad & Ontario Temple University School of Medicine Philadelphia, PA  19140 215 707.5036   Office 215 707.3494   Fax<\/p>\n

Most uts-guided pneumothoraces are the result of non-expandable lungs, they are usually not preventable (Chest 2006;130;1173-1184)<\/p>\n

<\/span>Safety Summary from PulmCCM<\/span><\/h2>\n

from the study (Thorax 2015;70:127-132)<\/p>\n

    \n
  • No blood products for coagulopathy or platelets for thrombocytopenia were provided to reduce thoracentesis bleeding risk.<\/li>\n
  • No routine chest films after thoracentesis.<\/li>\n
  • Bilateral thoracenteses were performed sequentially (without delay) about 40% of the time.<\/li>\n
  • Patients on ventilators were not routinely excluded.<\/li>\n
  • Ultrasound and hand suction (not vacuum bottles) were used routinely; pleural manometry was not.<\/li>\n<\/ul>\n

    Authors tracked patient factors (e.g., on a ventilator), procedure factors (needle passes, volume removed), and complication rates, which were 0.98% overall, including:<\/strong><\/p>\n

      \n
    • Iatrogenic pneumothoraces (0.6%)<\/li>\n
    • Re-expansion pulmonary edema or REPE (0.01%), with no deaths<\/li>\n
    • Bleeding episodes (0.18%), of which 5 were considered hemothorax (0.05%)<\/li>\n
    • Vasovagal reactions (0.06%)<\/li>\n<\/ul>\n

      Removing >1,500 mL was associated with more complications<\/strong> (3.1% overall), including 2.2% pneumothorax risk and 0.75% risk for re-expansion pulmonary edema.<\/p>\n

      Severe thrombocytopenia did not increase bleeding risk<\/strong>: among 53 patients with platelets under 20,000, there were no cases of hemorrhage. There was no association between INR and bleeding risk<\/strong>, among 301 patients undergoing thoracentesis with INR >3.1. Interestingly, elevated PTT was associated with complications (authors suspect as a marker for underlying disease or frailty).<\/p>\n

      Invasive or non-invasive mechanical ventilation did not increase the likelihood of a complication<\/strong>, among 1,377 patients. Unfortunately, the analysis was not stratified between invasive and non-invasive ventilation.<\/p>\n

      Two or more needle passes were associated with increased risk for pneumothorax.<\/strong> In an indication of their high proficiency, authors completed thoracentesis with one needle pass >99% of the time. They reported \u201cdry taps\u201d (zero fluid) in only 35 patients (0.4%). Authors believe they probably over-counted, rather than under-counted pneumothoraces (i.e. counting some cases of trapped lung as pneumothorax).<\/p>\n","protected":false},"excerpt":{"rendered":"
