About

The diagnosis of Growth Hormone deficiency in childhood requires the performance of an artificial pharmacological stimulation tests. There are number of substances that increase the secretion of growth hormone, among them Clonidine and Arginine. One of the possible side effects of both Clonidine and Arginine is a reduction in the blood pressure due to a decreased heart output and declined contraction of peripheral blood vessels. In cases where values of blood pressure at the end of the test are not recovered after two sessions of 15 minutes of physical activity, the patient is treated with I. V of 9%NORMAL SALINE (0. 20cc /Kg) administrated over 30-60 minutes.

The aim of the proposed study is to test whether administration of fluids during the combined Growth Hormone stimulation test Clonidine-Arginine will help in the recovery process from the test (blood pressure > 90/50 mmHg after performing physical activity defined as 15-minutes hike in two consecutive sessions). The study design will be randomized, controlled, 2 arms study.

Intravenous fluid administration

Experimental group

Description:

This arm will include 20 children who received Testoviron or Estrofem prior to the the stimulation test and 40 children who did not receive preparation prior to the stimulation test. Participants in this arm will be treated with I. V of 9%NORMAL SALINE (0. 20cc /Kg) administrated over 60 minutes. The fluids treatment will be initiated 90 minutes after the stimulation test will begin

Treatment:

Procedure: 9% Sodium Chloride (NaCl) IV

Control Group

No Intervention group

Description:

This arm will include 20 children who received Testoviron or Estrofem prior to the the stimulation test and 40 children who did not receive preparation prior to the stimulation test. Participants in this arm will not receive fluids intravenously during the stimulation test, unless it will be required due to safety reasons
