Observation And Study Of Electrolyte Disorder In Abdominal Sergury Patients

Objective To Analyse the incidence and regulation of electrolyte disorder in colorectal cancer surgery patients, gastric cancerl surgery patients and total hysterectomy patients before and after anesthesia induction.Methods Select gastric cancer surgery patients,colorectal cancer surgery patients,and total hysterectomy patients in the first affiliated hospital of guangxi medical university from 2013 to 2015, as gastric cancer surgery group (group G) respectively,colorectal cancer surgery group (group C) and total hysterectomy group (group H),150 patients in each group.Collect imformation of each patient. Monitor blood electrolyte concentration, mean arterial pressure (MAP) and heart rate (HR) at 24h before operation (To),30 min before anesthesia induction (T1), 1h after anesthesia induction (T2),2h after anesthesia induction (T3), at the end of surgery (T4).Intraoperative fluid infusion was managed according to intraoperative fluid management of the sixth edition of Miller’s Anesthesiology.Observe and record length of anesthesia, length of operation, type and dosage of liquid infused, blood loss, and urine output of each patient during operation. SPSS 16.0 was used in data processing,.Intra-group comparison was performed with t-test, comparison between groups was performed with one-way analysis of variance. Counting data was expressed by chi-square test measurement data was expressed by meanistandard (x±s)deviation. P< 0.05 was considered as statistically significance.Results There was no statistically significant difference in the length of anesthesia and operation, urine out put, blood loss, total liquid input of the three groups.Severity and frequency of electrolyte disorder:30 min before induction of anesthesia (Ti), the incidence of hypokalemia of the three groups compared to 24h before operation (To) increased (P< 0.05), the incidence of hypocalcemia of colorectal cancer surgery patients increased compared to 24h before operation (To). the incidence of hypokalemia of gastric cancer surgery patients is higher than the other two groups of patients (P< 0.05), the average serum potassium concentration at 30 min before induction of anesthesia (Ti)reduced compared to 24h before operation (To) (P< 0.05), and is lower than that of the other two groups (P< 0.05); The incidence of hypocalcemia of colorectal cancer Surgery patients at 30 min before induction of anesthesia (Ti)is higher than that of the other two groups of patients(P< 0.05).Conclusion Abdominal surgery patients are prone to electrolyte disorder before induction of anesthesia.The most common electrolyte disorder type is hypokalemia,the second most common is hypocalcemia. gastric cancer surgery patients has the most severe hypokalemia before induction of anesthesia, colorectal cancer surgery patients are prone to hypocalcemia before induction of anesthesia.
