Kundra TS, et al. - With an intent to define the minimum dosage of dexmedetomidine needed for abolition of post-spinal anesthesia (SA) shivering, researchers undertook this investigation. In this study, 0.258 ± 0.024 mcg/kg was reported as the minimum dose of dexmedetomidine required for abolition of shivering for patients with Grade 3 shivering and 0.295 ± 0.018 mcg/kg for patients with Grade 4 shivering, which was much less than the commonly administered dose.
