ClinConnect Summary

This clinical trial is looking at a new way to help manage pain after a type of weight-loss surgery called laparoscopic sleeve gastrectomy, which is often done for people with obesity. The study will test a pain relief technique called the external oblique intercostal block (EOIB). This method aims to reduce pain and the need for opioid pain medicines during the first 24 hours after surgery, while also trying to lower common side effects like nausea and vomiting. The goal is to make recovery more comfortable and possibly shorten the hospital stay.

Adults between 18 and 65 years old who are having this surgery might be eligible to join the study, as long as they don’t have certain health issues like long-term opioid use, chronic pain, severe heart, liver, or kidney problems, or allergies to pain medications. Participants will receive the EOIB treatment during surgery and will be monitored for pain levels and medication use afterward. It’s important to note that the study hasn’t started enrolling patients yet, and anyone interested would need to give informed consent and meet all the health criteria. This trial could offer a promising new way to improve pain control after weight-loss surgery.
