Pilot Study: Comparing the Duration of Action in Ultrasound-Guided Nerve Blocks with 10 Percentage Dextrose Versus Normal Saline Addition

This pilot study investigates whether adding 10% dextrose to local anesthetics in ultrasound-guided peripheral nerve blocks offers longer and more effective pain relief compared to normal saline. Conducted at Vinayaka Missions Medical College & Hospital, Karaikal, over six months, the randomized study will include 14 patients divided into two groups of seven each. Group A will receive a combination of local anesthetics with 10% dextrose, while Group B will  receive the same anesthetics with normal saline. The study focused on comparing the duration of anesthesia, onset of pain relief, patient satisfaction, and safety profiles between the two groups. Sensory and motor blocks were assessed every 2–3 minutes post-injection, and pain levels were recorded using the Visual Analogue Scale. The study included patients aged 10–80 years undergoing orthopedic or wound-related limb surgeries, with exclusion criteria such as ASA IV status, allergies to anesthetics, and coagulopathies. Results aim to determine if 10% dextrose can enhance block duration, reduce the need for rescue analgesia, and improve overall patient outcomes in clinical anesthesia practice.
