Changes in peripheral blood leucocytes following i.v. anaesthesia and surgery.
Sir,—Observations of leucocytosis following anaesthesia and surgery are certainly not new. Current interest is, for the most part, centred around possible depression of cellular immune response by the various anaesthetic agents on the cancer patient treated by surgery. The high incidence of apparently "anaphylactoid" or hypersensitivity-type adverse responses to the newer i.v. anaesthetic agent...
متن کاملGeneral anaesthesia and TrkA mRNA in peripheral blood mononuclear cells.
EDITOR: Surgery and anaesthesia are known to compromise immune functions. Induction of general anaesthesia even before skin incision reportedly increases plasma concentration of proinflammatory cytokines (tumour necrosis factor (TNF)-a, interleukin (IL)-1b) and also induces TNF-a and IL-1b release from blood cells [1,2]. On the other hand, nerve growth factor (NGF) and its high-affinity recepto...
متن کاملHyperventilation and cerebral blood flow.
Hyperventilation and Cerebral Blood Flow • Hypocapnic-hyperventilation has a profound, but probably temporary, effect on CBF, producing approximately a 2% decline in CBF for each 1 torr decline in Pcov Th' effect appears to be mediated through changes in perivascular pH of the cerebral resistance vessels acting directly on the vessel wall. At low PC0;( the vasoconstrictor effect of short-term h...
متن کاملObservations of blood lactate and pyruvate levels and excess lactate production during and after anaesthesia with and without hyperventilation.
Arterial blood levels of lactate and pyruvate and the production of excess lactate were studied in two groups of patients. One group of ten patients was anaesthetized with < 1 per cent halothane, nitrous oxide and oxygen and allowed to breathe spontaneously. The second group of twelve patients was anaesthetized with nitrous oxide and oxygen, and additional trichloroethylene or papaveretum, and ...
متن کاملHyperventilation and human calf blood flow.
COFFMAN, JAY D., AND PETER ALLY. Hyperventilation and human calf blood $0~. Am. J. Physiol. 21 I (5): 1255-1260. rg66.-Calf blood flow was measured in normal subjects by venous occlusion plethysmography, and capillary blood flow by the disappearance rate of an intramuscular injection of NaI131 before and during hyperventilation at 30 breaths/min for 3 min. Hyperventilation with room air produce...
