← Human Body & HealthWhy does a fever reduce the effectiveness of certain anesthetic drugs during prolonged surgery?
A)Decreased drug hepatic clearance
B)Reduced drug receptor affinity
C)Increased metabolic drug degradation✓
D)Enhanced renal drug excretion rate
💡 Explanation
The body raises its temperature during a fever to combat infection, accelerating metabolic processes, including drug metabolism, through thermoregulation. Because of increased metabolic drug degradation, the anesthetic is broken down faster, therefore its effect is reduced, rather than decreased clearance or altered receptor binding.
