Effects Magnesium Sulfate and Labetalol Infusion on Peripheral Perfusion and Pain in Nasal Surgeries

Summary

One of main risk of controlled hypotension during nasal surgeries is impaired perfusion. Peripheral perfusion of non-vital organs usually impaired earlier than vital organs. So, evaluation of perfusion of non-vital organ is considered to be adequate measure of patient safety during surgery. Many hypotensive agents such as dexmedetomidine, B blockers, magnesium sulfate and nitroglycerine had been used but we are in need to investigate its effects on peripheral perfusion. Postoperative pain related to nasal surgeries due to surgical trauma itself which induces the release of inflammatory mediators from neuronal and immune cells resulting in peripheral and central sensitization significantly affects recovery of patients. Magnesium sulfate and labetalol have analgesic actions besides their hypotensive effects but with different mechanisms.
