Incidence And Risk Factors Of Hypocalcemia In Intensive Care Unit

Objective:To investigate incidence and risk factors of hypocalemia in ICU of DaLian.Methods:44 Patients admitted in intensive care unit of eight the 3rd degree and grade A hospitals in DaLian .Patients'age,sex,diagnosis,serum total calcium, lactate, arterial blood gas measure-ments, albumin, time expourse to sun were recorded at the first day they admitted.Results:Hypocalcemia was defined as total Ca level less than 2.1 mmol/L.Incidence of hypocalcemia were 45.4%(20/44),Patients were divided into two groups based on serum total calcium level.There was no difference in age,sex and arterial blood gas PH between two groups.Lactate,albumin,time expourse to sun were different between two groups.18 of 44 patients were diagnosised sepsis,and incidence of hypocalcemia of sepsis,others,cardiovascular disease,trauma and nervous system disease were 61.1%, 50.0%, 40.0%, 40.0%, 12.5%.Conclusion:①Hypocalcemia in ICU paitents were common,incidence of hypocalcemia were 45.4%.②Risk factors of hypocalcemia were Lactate,albumin,time expourse to sun.③Incidence of hypocalcemia of sepsis was higher than other disease.
