Shivering, Spinal Anesthesia

The aim of this study is to compare the efficacy of magnesium sulphate, ondansetron, and dexmedetomidine in managing post-spinal anesthesia shivering. The primary aim is the time to cessation of shivering after drug administration, while secondary aim include hemodynamic parameters (heart rate, blood pressure, SpO₂ ) and the recurrence of shivering

\*Ketamine:\* Ketamine is a medication that can help reduce shivering by blocking certain nerve signals in the brain. It's like a "nerve blocker" that helps calm down the body's shivering response. \- \*Tramadol:\* Tramadol is a pain medication that can also help reduce shivering. It works by affecting the brain's temperature regulation centers, which helps to reduce the shivering response.
