Factors influencing epidural catheter migration.

摘要: The incidence and amount of migration epidural catheters was investigated in a prospective randomised study 153 women who required analgesia labour. Inward or outward occurred 36% patients. by 1-3 cm 21 (13.7%) patients 1 more 34 (22.2%); three (2%) migrated out through the skin. There were significant positive correlations between weight, body mass index, depth space. no relationship height, age, intervertebral space used duration catheterisation. Problems with block likely whom compared those limited to maximum +/- 0.5 cm. However, pattern problems different. All cases failed whose catheter 2.5 more. Unilateral blockade not if occurred.
