Summary

Neonatal tremor in healthy newborns often resolves with suckling stimulation. Persistent tremor may indicate underlying hypocalcemia or hypoglycemia in infants.

Area of Science:

  • Neonatology
  • Pediatric Neurology
  • Endocrinology

Background:

  • Neonatal tremor is a common clinical finding.
  • The underlying causes and diagnostic indicators require further elucidation.

Purpose of the Study:

  • To investigate the diagnostic utility of suckling stimulation in assessing neonatal tremor.
  • To correlate tremor resolution with metabolic parameters in healthy term neonates.

Main Methods:

  • A suckling stimulation test was administered to 102 healthy, full-term neonates exhibiting tremor.
  • Serum calcium and glucose levels were assessed in neonates with persistent tremor.

Main Results:

  • Tremor resolved immediately in 84 out of 102 neonates following suckling stimulation.
  • Persistent tremor was observed in 18 neonates, with 13 showing hypocalcemia and 5 demonstrating hypoglycemia.
  • No neonates with resolving tremor had hypocalcemia; only one had mild hypoglycemia.

Conclusions:

  • Suckling stimulation is a valuable, non-invasive test for evaluating neonatal tremor.
  • Persistent neonatal tremor after stimulation warrants investigation for metabolic disturbances like hypocalcemia and hypoglycemia.
