RESUMEN
Objective To explore the risk factors in post-polypectomy hemorrhage in rectum and to discuss the appropriate interventions.Methods A total of 313 patients with 373 polypi were included in this study. The clinical data were analyzed by SPSS 16 software. Results There were 313 patients with colorectal polypus curatively resected and 373 polypi in total.There were 11 (3.5%) patients subjected to post-polypectomy hemorrhage in rectum.Regression analysis showed that the independent risk factor of postpolypectomy hemorrhage in rectum was the hypertension of patients (P < 0.01 ) and this hemorrhage had no significant correlations with patientg'ender,age,size of polypus,pathological characteristics and the methods of polypectomy.Conclusions Hypertension of patients is an independent risk factor in post-polypectomy hemorrhage.
RESUMEN
Excessive oral and maxillofacial bleeding causes upper airway obstruction, bronchotracheal and gastric aspiration and hypovolemic shock. Therefore, the rapid and correct bleeding control is very important for saving lives in the emergency room. Despite the conventional bleeding control methods of wiring (jaw fracture, wound suture and direct pressure), continuous bleeding can occur due to the presence of various bleeding disorders. There are five main causes for excessive bleeding disorders in the clinical phase; (1) vascular wall alteration (infection, scurvy etc.), (2) disorders of platelet function (3) thrombocytopenic purpura (4) inherited disorders of coagulation, and (5) acquired disorders of coagulation (liver disease, anticoagulant drug etc.). In particular, infections can alter the structure and function of the vascular wall to a point at which the patient may have a clinical bleeding problem due to vessel engorgement and erosion. Wound infection is a frequent cause of postoperative active bleeding. To prevent postoperative bleeding, early infection control using a wound suture with proper drainage establishment is very important, particularly in the active bleeding sites in a contaminated emergency room. This is a case report of a rational bleeding control method by rapid wiring, wound suture with drainage of a rubber strip & iodoform gauze and wet gauze packing, in a 26-year-old male cerebral palsy patient with active oral and maxillofacial bleeding injuries caused by a traffic accident.
