Teleflex Highlights LMA® Gastro™ Airway Study, Which Shows Efficacy for Use in Upper Gastrointestinal Endoscopy

Teleflex Incorporated (NYSE: TFX), a leading global provider of medical devices, has announced that newly published research, in the February 2018 edition of the British Journal of Anesthesia, affirms the LMA® Gastro™ Airway with Cuff Pilot™ Technology yields a high airway insertion success rate and endoscopy success rate when used in patients undergoing upper gastrointestinal endoscopy.¹

The prospective study, by Nico Terblanche MD, FCA, MMED (Anes) and colleagues, who are independent from Teleflex, sought to determine the efficacy of the LMA® Gastro™ Airway in patients undergoing upper gastrointestinal endoscopy. The study observed 292 patients with ASA physical status classification 1 or 2, and low risk of pulmonary aspiration, who received standardized LMA® Gastro™ Airway insertion during the procedure. The study concluded that the endoscope and LMA® Gastro™ Airway insertion success was 99%, indicating LMA® Gastro™ Airway efficacy.¹

More than 6.9 million upper endoscopies are performed in the U.S. each year,² according to a 2009 study, and the use of moderate-to-deep sedation during endoscopy is a common practice. Respiratory depression from sedative drugs and airway obstruction requiring intervention are known risks associated with these procedures, with studies demonstrating hypoxemia can occur in 11-50% of cases.^3-5 However, today, many of these are undertaken without an airway management device in place.

The LMA® Gastro™ Airway is the first laryngeal mask specifically designed to enable clinicians to proactively manage their patients' airways while facilitating direct endoscopic access via the integrated channel. With the airway in place, clinicians can easily direct an endoscope and provide a patent airway for patient safety, which can facilitate monitoring of end tidal CO₂.

"The LMA® Gastro™ Airway was created in response to a true need for a controlled airway management solution for higher-risk patients undergoing routine upper GI proedures," said Justin McMurray, President and General Manager, Teleflex Anesthesia and Emergency Medicine Division. "As the market leader in supraglottic airways, Teleflex continues to develop innovative airway management devices that help advance clinical practice."

The peer-reviewed paper appears in the February 2018 issue of the British Journal of Anaesthesia, which is the oldest and largest independent journal of anesthesia. The study author was Dr. Terblanche, who works in the Department of Anaesthesia and Perioperative Medicine at Royal Hobart Hospital in Tasmania, Australia.
