RESUMO
Objective To explore the impact of using large dose norepinephrine on the anastomotic healing after esophagectomy.Methods Clinical data of data of 148 cases patients with esophageal cancer who were treated in Wuwei Tumor Hospital of Gansu Province with surgery from January 2014 to June 2016 were retrospectively analized.There were 7 patients who were used 25-67 mg ((32.6 ± 2.3) mg) norepinephrine because of the low blood pressure and other factors during the first 4 d postoperative as research group,and the other 141 patients who had not applied or applied the small dose were set as control group.The patients of two groups with postoperative anastomotic healing and fistula incidence were compared.Results There were 3 cases and 7 cases of postoperative patients appeared anastomotic fistula in the research group and the control group,the rate of anastomotic fistula were 42.86％ (3/7) and 4.96％ (7/141) respectively,the difference was significant (x2=9.78,P =0.001),and 2 cases appeared varying degrees residual gastric necrosis in the research group,all of them occurred in the patients with large dosage and long time.Conclusion There are great risk on the anastomotic fistula and residual stomach mecrosis if long time and large dose norepinephrine was used after esophagectomy,it should be caused enough attention for surgeons.
