MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641062327 A) filed by Adichunchanagiri University; and Adichunchanagiri Institute Of Medical Sciences, Mandya, Karnataka, on May 16, for 'analgesic efficacy of dexmedetomidine as an adjuvant to ropivacaine in ultrasound guided transversus abdominis plane block in inguinal hernia surgery a randomised controlled study.'
Inventor(s) include Dr. Noulaspure Anand; and Dr. Sarvesh. B.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "Postoperative pain after abdominal surgery can slow down patient recovery and lower satisfaction levels. The Transversus Abdominis Plane (TAP) block is a regional anesthesia technique that targets nerves supplying the front of the abdominal wall. Ropivacaine is commonly used because it provides good pain relief with little muscle weakness, but its effects may not last long enough. Researchers have added adjuvants like dexmedetomidine to improve and extend the pain relief.The main goal of this work was to study how well dexmedetomidine works when added to ropivacaine in TAP blocks for pain control after surgery. It compared how long the pain relief lasted, the quality of pain relief, patient satisfaction, and safety between ropivacaine used alone and ropivacaine combined with dexmedetomidine.Studies reviewed showed that adding dexmedetomidine makes the pain relief last longer, reduces the need for opioid painkillers, lowers pain scores, and improves patient satisfaction. At usual lower doses, there were no serious side effects, though higher doses could cause more sedation and a longer stay in the recovery area. Dexmedetomidine also has helpful anti-inflammatory and protective effects on nerves. Overall, the combination offers better postoperative pain management for abdominal surgeries and fits well into multimodal pain control approaches."
