Summary

This study compares two types of nerve blocks—serratus posterior superior intercostal plane block and serratus anterior plane block—for pain relief after minimally invasive pectus excavatum repair. Researchers will measure total opioid use in the first 24 hours after surgery, along with pain scores, side effects, and recovery time. The goal is to see which block provides better pain control and reduces the need for strong painkillers.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
serratus posterior superior intercostal plane block and serratus anterior plane block
What this could lead to
If one nerve block proves better, it could reduce opioid use and speed recovery after pectus excavatum surgery.
What could go wrong
This is a small observational study, not a randomized trial, so results may be less reliable and might not apply to all patients.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will include patients aged 15 to 25 years who are diagnosed with pectus excavatum and scheduled to undergo minimally invasive repair of pectus excavatum under general anesthesia. Patients who receive either bilateral serratus posterior superior intercostal plane block or bilateral serratus anterior plane block as part of routine perioperative analgesic care will be included.

Inclusion Criteria: * Patients aged 15 to 25 years * Diagnosis of pectus excavatum * Scheduled to undergo minimally invasive repair of pectus excavatum under general anesthesia * Receipt of either bilateral serratus posterior superior intercostal plane block or bilateral serratus anterior plane block as part of routine perioperative analgesic care * Written informed consent obtained from the patient or, for patients younger than 18 years, from a legal guardian Exclusion Criteria: * Refusal to participate in the study * Contraindication to regional anesthesia * Known allergy to local anesthetics or study analgesic medications * Chronic opioid use * Pre-existing chronic pain syndrome * Coagulopathy or use of anticoagulant therapy that contraindicates regional block application * Local infection at the block injection site * Neurological or psychiatric condition that may interfere with pain assessment * Incomplete perioperative or postoperative data * Conversion to another surgical technique or major intraoperative complication requiring a change in the routine analgesic protocol
