ABSTRACT
Objective To analyze the risk factors of the infusion pump to provide evidence-based basis for its safety management and monitoring.Methods Totally 1 000 pieces of questionnaires were issued for 100 infusion pumps from 9 grade-A tertiary hospitals in Beijing.The abnormalities and the correlation between the indexes were analyzed for the infusion pump,the indexes were compared on their effects on the abnormalities.Results Statistical analysis on data samples showed that the main factors included the manufacturer of infusion pump and pipeline,service time of infusion pump,compatibility between infusion pump and pipeline as well as the user department.Conclusion The management facility has to pose emphases on safety and utilization management as well as standardized application of the infusion pipeline so as to reduce adverse events efficiently.
ABSTRACT
<p><b>OBJECTIVE</b>To study the gastric function after esophagectomy and cardiectomy with vagus nerve preserved and reconstruction of gastric funds (VPRG)in patients with esophageal cancer (EC) and cardiac cancer (CC).</p><p><b>METHODS</b>Sixty-eight patients with early or middle staged EC or CC received esophagectomy and cardiectomy with vagus nerve preserved and reconstruction of gastric funds (VPRG),while other 68 patients esophagectomy and cardiectomy with vagus nerve severed and no reconstruction of gastric funds (VSNG) as control. The symptoms,the pressure of the residual esophagus and thoracic stomach, 24-hour pH monitoring, mean basic gastric acid output, gastric emptying time of the intrathoracic stomach,fasting serum gastrin level, fibreoptic endoscopic results were compared before and after operation between the two groups.</p><p><b>RESULTS</b>The patients with VPRG had less symptoms after operation than those with VSNG such as anorexia, belch, reflux, heartburn, nausea, diarrhea, postcibal satiety (P< 0.01). In VPRG group,compared with the results before operation,there were no significant differences in 24-hour pH monitoring,the mean basic gastric acid output, the fasting serum gastrin level,the gastric emptying time of intrathoracic stomach one month and one year after operation (both P > 0.05). The pressure of the residual esophagus above the anastomosis in VPRG group was significantly higher than that in VSNG group (both P< 0.05). Fibreoptic endoscopic examination revealed higher incidences of postoperative atrophic gastritis and reflux esophagitis in VPRG group one month and one year after operation than those in VSNG group (P< 0.01).</p><p><b>CONCLUSION</b>Preservation of the vagus nerve and reconstruction of gastric funds after esophagectomy and cardiectomy for esophageal and cardiac cancer can prevent digestive disorder and improve the life quality of the patients.</p>
