WebSpinal anesthesia reduced the shivering threshold in direct relation to the number of dermatomes blocked: delta threshold = 0.74 - 0.06 (dermatomes blocked); r2 = 0.58, P < … WebTramadol slightly decreases the threshold temperature for sweating, whereas the threshold temperatures for vasoconstriction and shivering decrease linearly with the tramadol plasma concentration. In adult surgical patients, Mohta et al. (2009) have shown that tramadol is an effective prophylactic drug for reducing the incidence of postanesthetic shivering. WebIsoflurane administration produced a dose-dependent reduction in the vasoconstriction and shivering thresholds, decreasing each approximately 4.6 degrees C at an end-tidal concentration of 1%. Residual analysis indicated that the vasoconstriction and shivering thresholds were decreased in a nonlinear fashion during isoflurane administration. movie theaters in milton delaware
