Correlación del calcio sérico con la escala BISAP en pancreatitis aguda.

OBJECTIVE: To determine the correlation between serum calcium levels and the BISAP severity scale in the emergency department. MATERIALS AND METHODS: An observational, analytical study was done with records of patients with acute pancreatitis in the emergency department of a general hospital from January to December 2019. The correlation formula was used to calculate the sample size. The sampling technique was non-probabilistic by quota. Calcium and BISAP were measured at admission and at 48 hours, calcium on a continuous and BISAP on a discrete scale. Pearson correlation, regression and projections were made. RESULTS: There were included 90 patients. At admission, the correlation (-0.405) between BISAP (discrete scale) and serum calcium (continuous scale) was statistically significant (p = 0.000); the patient with BISAP 0 had calcium of 8.685 mg/dL and with BISAP 5 had serum calcium of 7.490 mg/dL. At 48 hours of admission, the correlation (-0.732) between BISAP and serum calcium was significant (p = 0.000), more intense and maintained the inversely proportional relationship. CONCLUSIONS: The correlation between serum calcium and BISAPS is high and inversely proportional in acute pancreatitis. [ABSTRACT FROM AUTHOR]
