Comparison of QLB block and TAP block in morbid obese patients: a randomized controlled study.

What was studied

This randomized trial compared TAP and QLB-2 nerve blocks for pain after weight-loss surgery. The surgery was laparoscopic sleeve gastrectomy. The patients had severe obesity. They were put into 3 groups. One group had TAP, one had QLB-2, and one had no block. The team tracked pain scores and morphine use.

What they found

Both blocks were linked to lower pain scores and morphine use than no block. The TAP group used the least morphine overall. The QLB-2 block lasted longer than the TAP block. TAP took less time to perform, and people got moving earlier. Quality of life scores did not differ between groups.

What it means for patients

The authors say TAP and QLB-2 blocks were linked to less pain. They were also linked to less opioid need after this surgery. They say TAP used less morphine overall than QLB-2.

Why it is not certain yet

The groups had 44, 42 and 40 patients. They all had the same type of surgery. Quality of life was checked before surgery, at 48 h and at 1 week. The abstract does not say how long people were followed after that.
