Summary

This study looked at 82 adults who had hip surgery and received a nerve block (PENG block) for pain. One group got the pain medicine as a manual injection every 4 hours, while the other got it through a pump continuously. Researchers compared pain levels, opioid use, and recovery quality to see which method was better.

What this could mean

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

Active substance
bupivacaine
What this could lead to
If one method works better, it could improve pain control and reduce opioid use after hip surgery.
What could go wrong
This is a small, completed retrospective study, so results may not apply to all patients. The findings need confirmation in larger, prospective trials.

Who can take part

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

Who is studied

This study includes adult patients (ages 18-65) who underwent hip surgery at Tekirdağ Namık Kemal University Hospital between November 15, 2023, and November 15, 2024. All patients received Pericapsular Nerve Group (PENG) Block via a catheter for postoperative pain management, along with multimodal analgesia including tramadol PCA, IV paracetamol, and rescue NSAIDs. The study compares two PENG block administration techniques: intermittent bolus versus continuous infusion.

Inclusion Criteria Participants must meet all of the following criteria to be included in the study: 1. Patients who underwent hip surgery between November 15, 2023 - November 15, 2024. 2. Patients who received Pericapsular Nerve Group (PENG) Block via a catheter for postoperative analgesia. 3. Patients who received Patient-Controlled Analgesia (PCA) with tramadol. 4. Patients aged 18 to 65 years. 5. ASA I - III classification. 6. BMI ≤ 35 kg/m². Exclusion Criteria Participants who meet any of the following criteria will be excluded from the study: 1.
