The effect of hypothermic hemodilutional cardiopulmonary bypass (CPB) on plasma sufentanil and catecholamine concentrations was studied in four groups of ten patients each, receiving four different doses of sufentanil. Samples for measurement of sufentanil were obtained before CPB, at 15, 30, and 45 minutes of CPB, during rewarming, immediately after and 15, 60, and 240 minutes after CPB. In addition, in groups III and IV, which received the highest dose of sufentanil, blood samples were also obtained for measurement of plasma levels of epinephrine and norepinephrine. Sufentanil concentration decreased in all groups with the start of CPB (group I, 2.92 +/- 0.2 to 2.04 +/- 0.2; group II, 3.30 +/- 0.3 to 1.51 +/- 0.2; group III, 7.08 +/- 0.7 to 3.45 +/- 0.3; group IV, 10.33 +/- 0.5 to 4.59 +/- 0.5 ng/ml). No further decreases occurred during CPB but increases occurred with rewarming. The first measurement after CPB approached the concentration before CPB (group I, 2.82 +/- 0.3; group II, 2.56 +/- 0.5; group III, 4.42 +/- 0.4; group IV, 6.10 +/- 0.4 ng/ml). Norepinephrine concentrations demonstrated a wide variability with no significant changes. Epinephrine levels increased significantly during rewarming in both groups (group III, 141 +/- 23 to 279 +/- 79 pg/ml; P less than 0.05; group IV, 105 +/- 24 to 267 +/- 68 pg/ml, P less than 0.05). The stability of plasma sufentanil concentrations during CPB suggest that no measurable metabolism or excretion occurred. The increase with rewarming and after CPB suggest significant sequestration.(ABSTRACT TRUNCATED AT 250 WORDS)

D007036 Hypothermia, Induced Abnormally low BODY TEMPERATURE that is intentionally induced in warm-blooded animals by artificial means. In humans, mild or moderate hypothermia has been used to reduce tissue damages, particularly after cardiac or spinal cord injuries and during subsequent surgeries. Induced Hypothermia,Mild Hypothermia, Induced,Moderate Hypothermia, Induced,Targeted Temperature Management,Therapeutic Hypothermia,Hypothermia, Therapeutic,Induced Mild Hypothermia,Induced Mild Hypothermias,Induced Moderate Hypothermia,Induced Moderate Hypothermias,Mild Hypothermias, Induced,Moderate Hypothermias, Induced,Targeted Temperature Managements
D009638 Norepinephrine Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic.

D004837 Epinephrine The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.

D005283 Fentanyl A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance.

D000777 Anesthetics Agents capable of inducing a total or partial loss of sensation, especially tactile sensation and pain.
