Pump therapy mimics the physiological insulin secretion and has been shown to be a safe and effective method of insulin administration alternative to the method of multiple injections. Continuous insulin infusion provides greater flexibility in the timing of meals and snacks with higher treatment satisfaction. Programmed basal rates improve nocturnal glycemic control and help to minimize a pre-breakfast increase of blood glucose level (the dawn phenomenon). Moreover, CSII can reduce exercise-induced and nocturnal hypoglycemia. Insulin pump therapy is effective in lowering glycated hemoglobin levels without higher risk of severe hypoglycaemia and ketoacidosis. To achieve a proper metabolic control with this method of treatment, the patient and his family requires appropriate education including knowledge of diet management, insulin therapy and manual competence of pump device. Here we present general guidelines for patients education concerning insulin dosage, programming of basal insulin rates and meal boluses based on carbohydrates and protein-fat exchanges.</p>","PeriodicalId":11550,"journal":{"name":"Endokrynologia, diabetologia i choroby przemiany materii wieku rozwojowego : organ Polskiego Towarzystwa Endokrynologow Dzieciecych","volume":"12 1","pages":"45-50"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"26028533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
