Relationship between invasive and noninvasive measurements of gas exchange in anesthetized infants and children.

abstract：BACKGROUND:Postoperative nausea and vomiting (PONV) is a commonly observed adverse effect of general anesthesia. Recently, ondansetron, a new serotonin3 (5-hydroxytryptamine3) receptor antagonist was shown to be effective in the prophylaxis and prevention of chemotherapy-induced nausea and vomiting in children and adul...
