Abstract:
Objective To observe the changes of serum potassium concentration in rectal cancer patients from the admission to before the operation,to provide clinical evidence for preventing serum potassium disorder during and after their operation.Methods Monitoring of the changes of serum potassium concentration of 40 cases of rectal cancer patients according to three time points including the first day of admission,before taking of cathartics and the morning before operation.They were divided into different groups according to their age(young,middle age and elderly group),gender(male and female group),diet(normal,decreased slightly and serious decline group) and course(long,middle and short course group) of disease.The serum potassium concentration was observed between each time point of each group and SPSS13.0 statistical software was used to analyze the changes above.Results The mean of all patients' serum potassium concentration was (4.09 ± 0.62) mmol/L on the first day of admission,was (3.83 ± 0.46) mmoL/L before taking of cathartics that was decreased compared to the former and there was significant difference (P ＜ 0.01),it was (3.36 ±0.40) mmol/L on the morning of operation and had significant difference with the above two groups (P ＜ 0.01).It hadn't significant difference between different gender and age groups at different time points (P ＞ 0.05) except between the young group and the elderly group in the morning of the operation (P ＜ 0.05).There were statistically significant differences between the different diet condition and different course at anytime point (P ＜ 0.01).Conclusions The rectal cancer patients were possiblely in hypokalemia before operation,the causes might be relative to the long course of disease,the decreased diet,the aged and infirm,the diet structure change after admission and taking cathartics cleaning intestinal tract.
