[Use of norepinephrine in the treatment of septic shock].
The effects of noradrenaline were studied in 16 patients, with either a hyperkinetic septic shock syndrome or a septic shock resistant to dobutamine treatment. The study aimed to restore normal tissue perfusion pressure, assessed by a return to normal of urine output or blood pressure. An optimal left ventricular filling pressure, estimated by the pulmonary capillary wedge pressure, was obtained for each patient using a Swan-Ganz catheter. The administration of 10.6 +/- 0.5 micrograms.kg-1.min-1 dobutamine (starting dose: 6 micrograms.kg-1.min-1) was started when the cardiac index (CI) was less than 3.3 l.min-1.m-2 after vascular filling with plasma expanders. Patients became eligible for noradrenaline treatment when they fulfilled the following conditions: arterial systolic pressure (Pasys) less than or equal to 90 mmHg; systemic vascular resistances less than or equal to 600 dyn.s.cm-5; CI greater than 3.5 l.min-1.m-2; persistent oliguria (less than 30 ml.h-1). This drug was given at a constant rate with a starting dose of 0.5 micrograms.kg-1.min-1, increased every 10 min by 0.3 to 0.6 micrograms.kg-1.min-1 according to the effects on Pasys and hourly urine output. Eight patients received noradrenaline alone; the efficient dose was 0.9 +/- 0.2 micrograms.kg-1.min-1, and it was used for a mean 5.1 +/- 1 days. CI increased in those patients who were given both noradrenaline and dobutamine. Thirteen out of the 16 patients had a dramatic increase in urine output; only three patients remained oliguric. There were no effects on serum creatinine concentration, anion gap, intrapulmonary shunt and oxygen consumption.(ABSTRACT TRUNCATED AT 250 WORDS)
