Who should not have an intercostal nerve block?
If you are allergic to any of the medications to be injected, if you are on a blood thinning medication, if you have an active infection going on, or if you have poorly controlled diabetes or heart disease, you should not have an intercostal nerve block or at least consider postponing it if postponing would improve your overall medical condition. Likewise, if you have very poor lung function and would have great difficulty with a collapsed lung, an intercostal block may not be the treatment of choice.
