简要总结
Background and aims:
- In the Netherlands most patients with diabetes mellitus that are treated with insulin, use an insulin pen for insulin administration. The injection technique can influence the absorption rate of insulin.
- The aim of this study is to compare the effect of insulin injections using a 5 mm insulin needle with insulin injections using a longer needle, on HbA1c, bloodglucose levels, hypoglycaemic events, bleeding, bruising, insulin leakage and pain perception.
- Study Hypothesis: 'Insulin injected with needles of 5 mm can be given without a skinfold. The length of the needle will not influence HbA1c levels and bloodglucose levels'.
详细描述
- In this randomised, clinical trial with cross-over design, 52 patients with Diabetes type 1 and 2 using a 8 or 12 mm needle, are randomised into two groups.
- Group I starts using 5 mm needles for insulin administration, after 13 weeks group I returns to their previously used 8 or 12 mm needle
- Group II continues using their own 8 or 12 mm needle, after 13 weeks group II starts using 5 mm needles for insulin administration.
- During each visit the HbA1c level is measured and a copy is made of the logbook of the patient with the blood glucose measurements.
- Insulin doses and number of experienced hypoglycaemic events are registered at each visit.
- The opinion and experiences of the patients regarding the different needles are obtained by using a questionnaire.
- Within-group analyses are computed, using the Wilcoxon signed Ranks Test. Between-group analyses are computed using the Mann-Whitney U test.
