    Abstract

    Somatostatin has profound effects on both splanchnic and portal vascular beds. The effects of intravenous somatostatin (100 micrograms/h) on urinary volume, effective renal plasma flow, and glomerular filtration rate were compared with the effects of a control infusion of physiological saline in six normal subjects. Renal plasma flow and glomerular filtration rate were measured by primed constant isotope infusions of iodine-125 iodohippurate and chromium-51 edetic acid. Urinary volume, renal plasma flow, and glomerular filtration rate were measured during 20 minute clearance periods. During the control infusion urinary volume, renal plasma flow, and glomerular filtration rate remained essentially unchanged at 254 (SEM 3) ml/20 min, 568 (5) ml/min/1.73 m2, and 110 (2) ml/min/1.73 m2 respectively. From similar basal values the infusion of somatostatin led to a rapid decrease in all three variables. After 120 minutes of infusion of somatostatin urinary volume, renal plasma flow, and glomerular filtration rate were reduced to 148 (17) ml/20 min (p less than 0.01), 422 (7) ml/min/1.73 m2 (p less than 0.001), and 93 (3) ml/min/1.73 m2 (p less than 0.05) respectively. This effect on renal function should be borne in mind whenever somatostatin is used.
