| Objective The percutaneous transcatheter thromblysis (TCT) used by Dotter firstly for the successful treatment of angioembolism in 1974, interventional treatment (IT) has become one of the effective methods to treat blood vessel embolism and improve tissue ischemia. So it did to the treatment of superior mesentery artery embolism (SAME) .It has been proved that TCT improve rate of thrombolysis and decrease the side-effect of medication postoperatively to infuse the medication into embolus through percutaneous transluminal agiocatheter. But there's little study on the catheterization after percutaneous transluminal agiography (PTA) and transcatheter thromblysis. In China, routine nursing on SMAE patients just covers observation of early postoperative complication. However, little importance is attached to nursing which aims at intestines function after IT and nursing for the angiocatheterization patients. The purpose of this study is to provide theoretic foundation and references to the improvement of periIT nursing program for SMAE patients by observing related parameters reflecting changes in intestines function before and after IT, and also by working out early nutrition management, directing its implementation and evaluating its effects.Methods 29 cases with successful IT were selected and divided into 2 groups according to different term: group of routine IT patients from January 2001 to January 2003 and group of angiocatheterizecf patients from January 2003 to January 2005. Some parameters were observed at given time a day before operation and each day within 7 days after IT, and the changesbetween them were compared.ResultsThere is an significant statistics difference between improvement rate of intestines ischemic every day after IT (p<0. 01), with the obvious change on 1st day. symptoms and signs observed in two groups before operation were both significantly abnormal. But compared with a day after operation, they are obviously released on every post IT day (p<0. 05). On the 1st post interventional treatment day, they were much more released than the days before IT, but theres little change of them between 3rd day and 5th day after IT. Not until 7th day after operation, they came to normal level. Intestines function parameters observed before operation were worser than those after operation to some degree, including abdominal pain, abdominal distention, sound of intestinal movement, and anus exhausting. With the most severity on 1st day before IT , lowerer on the 1st day after IT , lowerest on the 3rd day and on 5th day or 7th day coming to the normal level. In addition, compared with the days before operation, there were significant changes in parameters reflecting intestines function postoperatively (p<0.01), which suggested that intestines function within a week after IJ did have significant change. On 7th day after IT, total body weight of nutrition therapy group was significantly increasing (p<0. 05), while routine therapy group was obviously decreasing (p<0. 05).Conclusions1.the releasing of symptoms and signs was a gradual decreasing trend, which suggested patients with IT still have the possibilities of ischemia of intestines at early time after IT. Changes in intestines function parameters showed that intestines function within a week after IT underwent a process to recovering, which suggested patients still had the possibilities of potential intestines ischemia.2. Postoperative nursing interventions should strengthen monitoring of intestines function and diet management of on certain time according to the characteristics of changes in patients' intestines function. Post IT monitoring was suggested to prolong to the 7th day after IT whenintestines function returned to the normal level before operation.3. There' s no significant difference between the complications and hospitalization days for the group of routine therapy and group of nutrition therapy, which suggested that catheterization carried out by this study didn' t have the negative effect on intestines function in the patients of group with catheterization, which was thought to be safe.4. The significant differences of intestines parameters between 5th and 7th day after IT suggested that it was a gradual process, which suggested they didn' t get back to the normal level instantly, but on the 7th day after IT. It suggested that intestine function within a week after IT underwent a process to recovering, nutrition therapy could help improve the intestine function, reduce the occurrence of disorders resulting from long-time fasting, thus contributing to the early recovery.
