VATSUltrasound-Guided Erector Spinae Plane Block for Postoperative Pain Management in Obese Patients After Video-Assisted Thoracoscopy

This clinical trial aims to compare the safety and effectiveness of two different methods for managing pain after a type of lung surgery called video-assisted thoracoscopy in obese patients. The two methods are Ultrasound-Guided Erector Spinae Plane Block (ESPB) and intravenous nalbuphine. The ESPB is a less invasive regional anesthesia technique that involves injecting a local anesthetic into a specific area of the back, while nalbuphine is a pain relief medication given through a vein. The study is important because adequate pain management after surgery can help prevent respiratory complications and improve recovery. The trial will include 102 patients who are planned for video-assisted thoracoscopy and meet certain criteria. During the trial, patients will be randomly assigned to either the ESPB group or the nalbuphine group. Patients in the ESPB group will receive the local anesthetic injection after the surgery, while patients in the nalbuphine group will receive the pain relief medication through a vein. The study will measure the total amount of nalbuphine used in the first 24 hours after surgery, the time until the first dose of rescue pain medication is needed, and the intensity of pain at rest and during movement. The study will also evaluate side effects related to the use of opioids, such as sedation, itching, and respiratory depression, as well as patient satisfaction with their pain management.
