We compared midazolam 0.2 mg.kg-1 and fentanyl 50 micrograms with thiamylal 4 mg.kg-1 for rapid sequence induction. We could use midazolam safely in patients with bronchial asthma or drug allergy. There was no difference in time from the beginning of induction to intubation between midazolam treated group and thiamylal treated group. Changes in systolic as well as diastolic blood pressure and heart rate during 2 hours from intubation were smaller in midazolam treated group than in thiamylal treated group. In midazolam treated group, no arrhythmias were observed at the time of intubation. We could reduce the amount of anesthetics in midazolam treated group during 2 hours from intubation. From the results mentioned above, we conclude that midazolam is a useful agent for rapid sequence induction. 相似文献

Optimal dose of epidural midazolam with saline for postoperative pain relief was investigated. Forty three patients for upper abdominal surgery were divided into 5 groups. Each group had either 10 ml saline only (saline group), 10 ml saline + midazolam 0.025 mg.kg-1 (0.025 group), 10 ml saline + midazolam 0.05 mg.kg-1 (0.05 group), 10 ml saline + midazolam 0.075 mg.kg-1 (0.075 group), or 10 ml saline + midazolam 0.1 mg.kg-1 (0.1 group) administered epidurally for complaint of postoperative pain. Blood pressure (BP), heart rate (HR), respiratory rate (RR) and sedation score (SS) were monitored for 120 minutes, and the time interval for next analgesics (TNA) was checked. In each group, BP was unchanged compared with preinjection level. HR changes were less in 0.05 and 0.1 group than in others. RR changes were less in 0.025 and 0.05 group than in others. Optimal SSs were obtained in 0.025 and 0.05 groups. In 0.075 and 0.1 groups, many patients fell into complete sleep (not responded to verbal command). TNA was about 2 hours in 0.025 and 0.05 groups, over 6 hours in 0.075 and 0.1 groups. Complete sleep was the cause of long TNA in 0.075 and 0.1 groups. It was concluded that optimal dose of epidural midazolam with saline 10 ml was 0.05 mg.kg-1 for postoperative pain relief after upper abdominal surgery. 相似文献

Positioning of patients with cervical spinal lesions under general anesthesia may lead to serious neurological complications. The authors attempted awake pronation in eighteen patients to minimize the risks. In all patients, cervical instability or cervical spinal cord compression was diagnosed, and posterior fusion or laminoplasty under general anesthesia was planned. Naso-tracheal intubation was performed by broncho-fiberoptic scope under topical anesthesia and light sedation. After tracheal intubation, pronation was completed while patients were still awake. Twelve patients could change their position almost by themselves, and needed only a little assistance of the medical staff. After the patients settled in appropriate position, general anesthesia was induced. Neurological status was assessed before and after the intubation, and just before the induction of general anesthesia, to prove the absence of complications. Operations were accomplished without major troubles in all patients. During post anesthetic interviews, eight patients had memory of the positioning, but none of them had any complaints about the procedure. Awake pronation may be useful to minimize the risk of neurological complications related to positioning of surgical patients, and also need less assistance by medical staff. 相似文献

Verapamil is widely used for the termination of paroxysmal supraventricular tachycardia (PSVT) with little proarrhythmic effect. We describe two cases of PSVT that changed to non-sustained polymorphic ventricular tachycardia after administration of verapamil. Electrophysiological study revealed atrioventricular nodal reentrant tachycardia in the first case, and atrioventricular reentrant tachycardia due to a concealed left lateral accessory pathway in the second case. Catecholamine-induced automaticity was one of the possible mechanisms of VT in the first case, but the mechanism is unknown in the second case. 相似文献

Acute pancreatitis occurring in gastric aberrant pancreas treated with surgery and proved by histological examination 总被引:2,自引:0,他引:2
We describe a case of gastric aberrant pancreas with acute pancreatitis. Barium meal examination, endoscopic examination and computed tomography of a 32-year-old man with abdominal pain revealed a submucosal tumor, about 3.5 cm in diameter, at the angulus of his stomach. Endoscopic ultrasonography revealed a hypoechoic mass with anechoic capillary areas. His serum amylase level was high at 262 IU/l. Laparoscopy-assisted local resection was carried out. The resected tumor revealed pancreatic tissue with extensive neutrophil infiltration in the gastric wall and fat necrosis in the subserosa. There are few cases of histologically proven acute pancreatitis in gastric aberrant pancreatic tissue. 相似文献

Intussusception is rare in adults. We describe a 47-yearold man with ileal schwannoma that led to ileocolic intussusception. Abdominal ultrasonography, abdominal CT scan and barium enema confirmed an ileal tumor. Colonoscopy revealed a peduncular submucosal tumor (SMT) 75 mm long with an ulcerated apex at the ascending colon. The provisional diagnosis was a gastrointestinal stromal tumor of the terminal ileum. Ileocecal resection was carried out and the tumor was histologically diagnosed as schwannoma. Abdominal pain resolved postoperatively. This case reminds us that ileal schwannoma should be included in the differential diagnosis of intussusception caused by an SMT in the intestine. 相似文献

To analyze the recent change in the long-term survival of patients with dilated cardiomyopathy (DCM), the present study comprised consecutive 111 patients with ejection fraction <50% and left ventricular end-diastolic diameter >58 mm. who were admitted to hospital from January 1983 to December 1994. The patients were divided into 2 groups: group A who were diagnosed before 1989 and group B diagnosed after 1990. Basic characteristics at diagnosis, including age, NYHA functional class, left ventricular end-diastolic diameter and ejection fraction, were similar between these 2 groups. Calculated survival rate at 5 years was 90.0% in group B in contrast to 62.3% in group A. Event-free survival also improved in group B. In group B, beta-blockers and angiotensin converting enzyme inhibitors were more frequently used than in group A (p<0.0001) whereas digitalis and other positive inotropic agents were significantly less used. Left ventricular ejection fraction was significantly improved during the follow-up period in patients treated with beta-blockers compared with those not treated with beta-blockers. These data indicate a significant improvement in the survival of patients with dilated cardiomyopathy after 1990, which may be explained by the change of medical treatment, especially the use of beta-blockers. 相似文献

OBJECTIVE: In recent years, the number of elderly patients with early gastric cancer (EGC) has steadily been increasing. In our institute, endoscopic submucosal dissection (ESD) involving the use of an insulated-tip diathermic knife (IT-ESD) was introduced for the treatment of mucosal gastric carcinoma in 1996. The purpose of this study was to evaluate the effectiveness of IT-ESD for the treatment of elderly patients with EGC. MATERIALS AND METHODS: A total of 144 patients with EGC were treated at Shikoku Cancer Center in the 5-year period from January 2000 to December 2004, including 53 patients over 75 years old. The performance status (PS) for all patients was less than 2. We compared patient's backgrounds, the one-piece resection rate, complete resection (CR) rate, operation time, bleeding rate, perforation rate, blood pressure, and peripheral oxygen saturation (SpO(2)) between patients over 75 years of age (elderly group) and the remaining 91 younger patients (non-elderly group). RESULTS: The rate of having underlying disease was significantly higher for the elderly group (p<0.05) and we found no significant difference for the one-piece resection rate, CR rate, operation time, bleeding rate, and perforation rate between the 2 groups. There were also no significant differences for the frequency of the use of oxygen, pressor and depressor between the 2 groups. CONCLUSION: There was no significant difference in the outcome resulting from ESD between the 2 groups. Our study proves that ESD is a feasible treatment for elderly patients with EGC PS of less than 2. 相似文献

We describe an 87-year-old woman with a large ileal gastrointestinal stromal tumor (GIST) causing hemoperitoneum. A CT scan demonstrated a large heterogeneous mass measuring about 13 cm × 11 cm in the pelvis and hemoperitoneum, with a non-uniform enhancement pattern. The mass was diagnosed as a GIST originating from the gastrointestinal tract. She underwent an urgent laparotomy and an ileal GIST with a rupture was found 130 cm from the anal to the Treitz’s ligament. Hemoperitoneum caused by ileal GIST rupture is a rare condition. Bleeding in the large tumor leading to rupture of the capsule might cause hemoperitoneum in the present case. 相似文献
