An Integrated Artificial Intelligence Approach for Predicting Analgesic Time Based on Nalbuphine Versus Morphine as Adjuvants to Bupivacaine in Ultrasound-Guided Supraclavicular Block

25 ml of 0.5% bupivacaine combined with 5 ml of normal saline, administered via ultrasound-guided supraclavicular brachial plexus block as a control intervention

25 ml of 0.5% bupivacaine combined with nalbuphine at a dose of 50 µg/kg, administered via ultrasound-guided supraclavicular brachial plexus block

25 ml of 0.5% bupivacaine combined with morphine at a dose of 50 µg/kg, administered via ultrasound-guided supraclavicular brachial plexus block
