In the postoperative treatment of ruptured abdominal aortic aneurysm surgery, the relationship between intra-abdominal pressure (IAP) and the clinical course is not been clearly understood. From April 2000 to January 2003, we treated 109 cases of abdominal aortic aneurysm surgery (non-rupture 71 cases, rupture 38 cases) and measured intra-abdominal pressure in 30 of the ruptured cases which we analyzed in this study. The patients were divided into 2 groups. The H-group included 12 patients with maximum IAP equal to or higher than 20mmHg, and the L-group included 18 patients with a maximum IAP less than 20mmHg. Clinical characteristics were compared between the 2 groups. The mean age was 79.3±7.6yr in the H-group and 70.7±10.1yr in the L-group (p=0.019). Preoperative shock was diagnosed in 83.3% of the H-group patients, and 61.1% of the L-group patients the (p=0.26). Postoperative maximum values of intra-abdominal pressure were 22.3±2.0mmHg in the H-group, and 15.4±2.4mmHg in the L-group. Duration of intubation was 87.7±110.0h in the H-group, and 25.1±29.2h in the L-group (p=0.04). Food intake was started 14.4±11.2d after surgery in the H-group, and 8.5±4.8d after surgery in the L-group (p=0.094). The length of ICU stay was 6.7±6.5d in the H-group, and 2.9±2.1d in the L-group (p=0.033). Length of hospital stay after surgery was 54.1±25.8d in the H-group, and 25.2±6.8d in the L-group (p=0.001). Complications occurred in 8 cases out of 11 surviving cases (73%) in the H-group, and in 3 cases out of 17 surviving cases (18%) in the L-group (p=0.0024). Complication in the H-group included acute renal failure, paralytic ileus, respiratory failure, abdominal wall dehiscence, and acute arterial occlusion, and that in the L-group included acute renal failure, upper limb paresis, and lower limb paresis. Monitoring of intra-abdominal pressure was considered beneficial to recognize complication and decide therapeutic strategy after ruptured aortic aneurysm surgery.

The experience at the time of a patient’s death can affect the mental health of bereaved families. Performing death pronouncements is an important skill for end-of-life care. However, almost no educational content regarding death pronouncements is presently included in medical educational programs. We have created a guidebook for “Physician behavior at the time of death pronouncement” based on the results of a questionnaire given to the families of deceased patients that included several items related to this topic. The purpose of this research was to investigate the educational effect of using this guidebook. The guidebook was given to 4th-year medical students attending the Yokohama City University School of Medicine. A survey was then conducted to assess evaluations of self-practice and feelings of difficulty at the time of making death pronouncements both before and after the class. Among the 39 students who provided valid responses, the majority (89.5%) indicated that they had difficulty with the item regarding “the specific method of death pronouncement.” A significant improvement was observed between the responses obtained before and those obtained after the class. We concluded that our guidebook for physician behavior at the time of death pronouncement might be useful for the education of medical students.
