Popis: | Spontaneously occurring hypoglycemia has been described in children with severe acute congestive heart failure. Hypoglycemia may he the result of an increase in glucose utilization in tissues, a decrease in glucose production, or a decrease in the dietary intake of nutrients. To determine whether hypoglycemia may also occur in congenital heart disease with volume overloading, we investigated glucose metabolism during and after an 18-hour fast in nine lambs with an aortopulmonary left-to-right shunt and nine control lambs. Plasma levels of hormones involved in the endocrine control of glucose metabolism were determined. The glucose production rate (rate of appearance [R-a]) was studied using [U-C-13]glucose. Gluconeogenesis through the Cori cycle was estimated by measuring glucose C-13 recycling. The arterial glucose concentration (3,409 +/- 104 v 4,338 +/- 172 mu mol/L, P |
