From: Conventional and Specific-Pathogen Free Rats Respond Differently to Anesthesia and Surgical Trauma
Representative blood pressure traces from SPF (a) and Conventional (b) male Sprague Dawley rats taken under isoflurane anesthesia following surgical instrumentation. Values represent mean ± SEM of n = 5 rats from each colony. SP = systolic pressure; DP = diastolic pressure; PP = pulse pressure calculated from SP – DP; MAP = mean arterial pressure; HR = heart rate. *p < 0.05 compared to Conventional rats. Power (1-β err prob) = 0.97 (Critical t = 1.86, Df = 8, α = 0.05, outcome measure = PP).
