WebFig 1 Effects of anaesthetics on the shivering threshold in rabbits. Shivering threshold was 37.0 (0.5)°C during nitrous oxide alone, 36.4 (0.5)°C during the combination of nitrous oxide and isoﬂurane, and 35.9 (0.4)°C during isoﬂurane alone. Each anaesthetic or anaesthetic combination totalled 0.3 MAC. Individual thresholds are shown ... WebAccording to Alfonsi and coworkers, nefopam and clonidine reduce the shivering threshold by 0.7°C (to 35.7°C); however, nefopam has been reported to induce seizures and anaphylactic reactions, and its availability is primarily in European countries.21A combination of buspirone and dexmedetomidine has been shown to additively reduce the …

Webshivering identiﬁed the thermoregulatory threshold for this response. Arterial blood was sampled for gas analysis at the shivering threshold in each rabbit. Morphometric … WebThe shivering threshold (at a designated mean skin temperature of 34 [degree sign]C) was calculated from measured core and mean skin temperatures when shivering intensity decreased significantly. The shivering threshold was thus the corrected core temperature when shivering stopped.
