From Saturday morning to about noon Monday, 23 people sought help from the six Omaha-area Alegent Creighton Health emergency departments for weather-related injuries.
Jodi Hoatson, spokeswoman for Alegent Creighton, said eight of the cases were for exposure and 15 were for slips and falls.
The exposure cases were not serious enough to require admission, she said.
Treatment usually involved administering warm fluids via IV, or wrapping the individual in a blanket inflated with warm air.
The Methodist Health System also had several people seek emergency room treatment for injuries from falls, said spokeswoman Claudia Bohn. No cases of hypothermia were reported.
The Omaha area in the past week had its coldest weather in about four years, according to the National Weather Service.
The temperature dropped to 11 degrees below zero Monday morning in Omaha, and wind chills were in the 20-below-to-35-below zero range.
