“…Two studies (1 sevoflurane and 1 propofol) compared the effect of aging between young and elderly on CVR-CO 2 , 25,26 and an another study compared the effect of sevoflurane and propofol in elderly patients. 27 However; each of the studies had different definition for elderly.…”

“…Studies have shown that both inhalational agents [5][6][7][8][9][10][11][12][13][14][15][16] and intravenous agents [17][18][19][20][21][22][23][24] have variable effects on CVR-CO 2 . This effect is further modified by many physiological factors (age, body position) [25][26][27][28][29] and other medical comorbidities (diabetes, hypertension, stroke, intracranial pathologies). 9,30-41 Adding nitrous oxide (N 2 O) with anesthetic agents further alters the CVR-CO 2 and exact mechanism for this effect is not clear.…”

“…Both studies were conducted in awake patients. Nishiyama et al [13] showed that cerebrovascular CO 2 reactivity in elderly patients was lower than that in young patients during sevoflurane anesthesia. Kessler et al [18] reported that a reduction in vasomotor reactivity, as measured by Doppler-CO 2 test, was a strong predictor for the postoperative temporary confusional state.…”

“…Several studies have evaluated the effects of propofol or sevoflurane on cerebrovascular circulation and CO 2 reactivity [11][12][13][14]. Matta et al [11] examined cerebral CO 2 reactivity during propofol-induced electrical silence of the electroencephalogram in 10 patients, and found that cerebral CO 2 reactivity remained intact during propofol anesthesia.…”
