Blood CirculationIn the decade in which the nitrous-oxide method for the determination of coronary blood flow has been used, much information has been accumulated both in experimental animals and in man. The available data in man have been reviewed briefly. Since this technique is applicable to ...
Inhalation of 60% nitrous oxide in oxygen by seven adult male volunteers for 60 min was found to increase significantly polymorphonuclear leucocyte (PMN) chemotaxis, but not to influence total white or PMN blood cell counts. Also, the addition of morphine 0.2 mg kg 1 1 i.v. during the brea...
which can be broken down todehydroascorbic acidandnitric oxide. The nitric oxide formed reacts with atmospheric oxygen and water to yield a mixture of nitric andnitrous acids; this serves as a sink for the removal of excess nitrous acid from the system, as nitrate is comparatively unreactive....

A comparison has been made ...
Nitrous oxide challengeCirculatory obstructionIt has not been previously established whether venous gas emboli dissolve from pulmonary blood vessels into adjacent airways, or pass as microbubbles directly into the systemic circulation. We reported here the quantitative recovery of embolized gases from the ...
The effects of 3 micrograms.kg-1.min-1 dobutamine on hepatic circulation and oxygen balance were examined in patients anesthetized with enflurane, nitrous oxide, and oxygen for liver surgery. Dobutamine did not cause a significant increase in hepatic arterial blood flow. However, total hepatic ...

Nitrous oxide (N2O) has been used in clinical anaesthesia for more than 150 years. Its use is encouraged in combination with new anaesthetics to reduce the cost. Nevertheless there is some evidence to show that N2O impairs myocardial function: e.g. producing a decrease in myocardial ...
