rachi morphine anesthesia clinical trials

Efficacy and Safety of Intravenous Lidocaine Versus Placebo in Patients Receiving Morphine-rachi Analgesia

This study looks at using a common painkiller called lidocaine, given through a drip, alongside standard spinal pain relief (morphine) during major tummy surgery. We want to see if lidocaine helps reduce the amount of morphine needed for pain relief in the two days after surgery.
