Abstract: ［Abstract］Objective〖HTSS〗To investigate the risk factors of lifethreatening asphyxia hematoma after thyroid surgery, and to provide reference for clinical work.
〖HTH〗〖WTHZ〗Methods〖HTSS〗A total of 14 patients(bleeding group) with lifethreatening asphyxiated hematoma caused by postoperative thyroid hemorrhage were screened by the case retrieval system. At the same time, according to the operating period, surgeon, anesthesia, etc., the condition was 1〖DK〗∶2. The proportions were matched and 28 patients with thyroid surgery without bleeding were selected(control group). The basic data and related indicators of the two groups of patients were compared, and multivariate logistic regression analysis was used to determine the risk factors of lifethreatening asphyxia hematoma caused by postoperative thyroid hemorrhage.
〖HTH〗〖WTHZ〗Results〖HTSS〗The proportion of total thyroidectomy in the bleeding group was lower than that in the control group. The proportion of papillary carcinoma in the pathological type was lower than that in the control group. The postoperative hospital stay was longer than the control group, and the difference was statistically significant(P＜0.05). Multivariate logistic regression analysis showed that the surgical procedure was a risk factor for airway obstruction caused by postoperative thyroidectomy. The risk of this complication after partial thyroidectomy was 9.116 times that of total thyroidectomy.
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗 Partial thyroidectomy is an independent risk factor for hemorrhagic hematoma after thyroid surgery.
