A cold spray eases pain during blood draws for critically ill patients

Getting blood from critically ill patients is hard work. Their bodies are fragile, and the pain of a needle stick can be intense. A new trial tested a simple cold spray to help with this. The spray uses vapocoolant to numb the skin quickly. It was compared to a fake spray that looked the same but had no active medicine. The study involved 201 adults in intensive care units across French hospitals. Ninety-four percent of them received the assigned treatment. Ninety-two were included in the final analysis. The main goal was to measure pain right after the needle went in. Results showed the cold spray worked better than the fake spray. Pain scores were lower with the real spray in every scenario tested. The difference was clear and consistent. No serious side effects were reported. Patients tolerated the spray well. Some people stopped the study early, but they were not counted in the final results. This trial gives doctors a practical tool to make blood draws less scary for their patients.
