Potassium is distributed throughout the body. It is concentrated mainly within the cell as the predominant cation. The kidney plays an important role in regulation of potassium levels. This study was undertaken with the aim of staying the behaviour pattern of serum potassium after thiopental. The clinical manifestations of hypokalaemia do not usually occur until the serum potassium has fallen below 2.5 mEq/L. The predominant sign is muscular weakness resulting into a picture of dyspnea patients exhibiting 'Fish mouth breathing'. All patients were belonging to paediatric children age group ranging from 4 to 17 years. Thiopental produce small, but statistically highly significant decrease in serum potassium in pediatric age group.
