When a person stops breathing or has a heart attack outside the hospital, doctors rush to give them medicine to restart their heart. Usually, doctors try to find a vein in the arm or neck to put the medicine in. Sometimes, they cannot find a vein quickly enough. In those cases, they might use a special needle that goes into the bone near the hip or knee. This is called the intraosseous or IO route. A new big study looked at how well this method works compared to using a normal vein, which is called the intravenous or IV route.
This study looked at data from more than 245,000 patients. It compared people who got medicine through the bone with those who got it through a vein. The results were clear and important for emergency teams everywhere. The team found that using the bone needle was linked to lower chances of the heart starting to beat again on its own. This is a very serious problem because getting the heart to beat again is the first step to saving a life.
The study also looked at how long the heart stayed beating and how well the brain worked after the patient left the hospital. People treated with the bone needle had much lower chances of having a good brain outcome. In fact, the chance of a good brain result was about 42 percent lower for those who got the medicine in the bone. This means the bone method is not as good as the vein method for helping the brain recover.
Survival rates were also much lower for patients treated with the bone needle. The chance of surviving until they left the hospital was about 41 percent lower. The chance of surviving for a short time after the event was also much lower. These numbers show that the bone needle does not work as well as the standard vein line. The study showed that the bone method is significantly worse for these important health results.
Doctors say that if you can find a vein, you should use it. The bone needle is a backup plan when a vein cannot be found quickly. Emergency teams need to know that using the bone needle might hurt the patient's chances of survival. They should try very hard to find a vein first. This study helps doctors make better choices to save lives during these very scary emergencies.
