A woman aged in her 40s has been flown to hospital in a critical condition following a two-car crash in Rouse Hill this morning.

The Mounties Care CareFlight Helicopter was tasked by NSW Ambulance shortly before 9am and landed in a paddock nearby the scene.

CareFlight’s critical care team and NSW Ambulance paramedics worked together on scene to treat the patient. NSW Fire and Rescue worked to extricate the patient from the wreckage with assistance from NSW Police, NSW Ambulance, and CareFlight. The other driver did not require hospitalisation.

CareFlight’s specialist doctor and NSW Ambulance critical care paramedic treated the woman for significant injuries to her legs, arms, and injuries to her face, as well as for shock. She was intubated and placed into an induced coma to stabilise her before a short transport via ambulance to the helicopter.

The woman was then flown to Westmead Hospital in a critical condition.
