Comparing two nerve block techniques for breast surgery pain relief

This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

After breast removal (mastectomy) surgery, pain can be significant and slow down recovery. This trial is testing two different nerve block techniques—special injections given near the chest muscles to numb the surgical area—to see which one works better at controlling pain after surgery. Both techniques use ultrasound imaging to guide the needle safely to the right location.

Pain after mastectomy can make it harder for patients to move around, delay healing, and sometimes lead to longer hospital stays. While strong pain medications like opioids can help, they often cause drowsiness, nausea, and constipation. This treatment offers a way to manage pain without those side effects, but doctors need to know which nerve block technique works best.

Do you qualify?

You likely qualify if…

you are a woman between 18 and 75 years old
you are scheduled for planned breast removal surgery
you are in generally good to moderate health (ASA physical status I, II, or III)
you are willing to provide written consent to participate

You likely don't qualify if…

you are in very poor health or have severe medical complications (ASA physical status IV or V)
you are taking blood-thinning medications or have a bleeding disorder
you have a known allergy to local anesthetic medications
you are pregnant or might be pregnant
you have severe heart disease, kidney failure, liver failure, or chronic nerve or mental health conditions

What participation looks like

You will be randomly assigned to receive one of two types of nerve blocks before your mastectomy surgery. A doctor will use ultrasound imaging to guide a needle to place numbing medication near the chest muscles, either under the front chest muscle (Group 1) or near the back of the shoulder blade (Group 2). After surgery, the research team will monitor your pain levels and recovery to compare how well each technique works.
