This rescue helicopter provides emergency services to a New Zealand island with the help of a portable ultrasound

Scattered across 150,000 square kilometers of beautiful farm land, mountainous terrain, and rugged coastline, South Island is the larger of New Zealand’s two major islands. It’s served by various medical centers and small hospitals, but few specialized hospitals in the south-eastern city of Dunedin.

And while the scenery of this Lord of the Rings landscape is stunning, its unreliable roads can make it difficult to quickly reach a hospital in an urgent situation. Fortunately, the Otago Regional Rescue Helicopter provides emergency rescue services to people and communities across the lower South Island 365 days a year.

The team is airborne within five minutes of receiving an emergency call. Equipped with life rafts, stretchers, portable oxygen, GPS, radio directional finders, night-vision goggles and its latest addition — a handheld portable ultrasound from GE Healthcare called Vscan Extend™[1], the team provides immediate care and airlifts critically ill patients to Dunedin Hospital.

In the hands of an aeromedical paramedic or emergency specialist, ultrasound is most often used to “see” under the skin and evaluate the heart.

It’s particularly beneficial on a helicopter, where seeing provides greater clarity than listening. “It’s so difficult to use a stethoscope, with the noise and the vibrations,” says intensive care specialist, Dr. Markus Renner.

The Vscan Extend™ is the size of a smartphone and has a dual probe, which enables clinicians to make focused assessments and accelerate treatment decisions at the point of care. “The system is small, lightweight, and affordable,” says Renner.

Renner is an advocate for the use of ultrasound in medical emergencies, “There were several indications for using portable ultrasound in the helicopter.” These included both diagnostic applications such as assessing cardiac activity, and checking for internal bleeding, thoracic injuries or pulmonary embolism (blockage of an artery in the lungs) and interventions, such as easily locating veins to apply intravenous medications to pediatric patients.

Renner recently treated a patient in shock, who had abnormally low blood pressure and hypoxia — an inadequate amount of oxygen in the blood. “The paramedic at the scene made the reasonable assumption under the circumstances that the patient had pneumothorax (a collapsed lung) and was experiencing progressive buildup of pressure, so he wanted to decompress the chest,” he says.

But the ultrasound showed the lung sliding, eliminating the possibility of pneumothorax, which led the team to look for the actual cause of shock. “With ultrasound, we were able to avoid a procedure that wasn’t indicated,” Renner adds.

He also anticipates cases where ultrasound could lead to the triage of unstable trauma patients who have free abdominal fluid directly from the helicopter to the operating room, rather than first being sent to the emergency department for further diagnostics. “By bypassing the emergency department, you would gain time and hopefully make a difference in the outcomes for those patients,” he says.

In the coming months, Otago Regional Rescue Helicopter Service plans to train its paramedics to use the ultrasound technology, while Dunedin Hospital undertakes more widespread ultrasound training of its intensive-care registrars.
