Introduction: An altered level of consciousness can be commonly seen in patients admitted to the intensive care unit (ICU). A decreased level of consciousness correlates to increased morbidity and mortality. Study aimed to see the level of consciousness in critically ill patients or patients of intensive care unit (ICU) and to study level of electrolytes in critically ill patients or patients of intensive care unit (ICU) Material and methods: A total of 100 randomly selected patients from 4 different intensive care units were enrolled for the study. GCS Score and lab parameters comprising the serum electrolytes Na, K, Cl of the patients on Day one of ICU admission were recorded and the mean levels calculated. General and systemic examination of the patients was also done.

Result: Our results clearly show a reduced or low mean sodium level (134±7.5 meq/L) in 30% patients of the ICU. The distribution of patients in each subgroup of GCS was unequal; mostly patients exhibiting well preserved consciousness state. The mean serum sodium level in each group of GCS is variable and cannot be graded with progressive decline in sensorium. Hence we cannot correlate the altered consciousness levels with the degree of hyponatremia. Conclusion: An accurate and reliable evaluation of the state of consciousness in Intensive Care Unit patients is of primordial importance for their management. Electrolyte disturbances are also common in ICU settings. Timely recognition, a high index of suspicion and a thorough understanding of these abnormalities are necessary to ensure their correction and reduce morbidity and mortality.
