Chlorhexidine Gluconate Dressings Reduce Bacterial Colonization Rates in Epidural and Peripheral Regional Catheters

Table 2

Local infection rates, catheter colonisation, and catheter removal.

	Conventional; ()	CHG; ()	value^†
Local infection as reason for removal of epidural (yes/no)	6/59	6/60	>0.99
Local infection as reason for removal of peripheral catheter (yes/no)	10/96	4/104	0.96
Overall tip colonisation (yes/overall)	35/166	5/161	<0.0001
Overall insertion site colonisation (yes/overall)	70/170	14/162	<0.0001
Epidural tip colonisation (yes/overall)	8/60	0/57	0.0062
Epidural insertion site colonisation (yes/overall)	19/61	5/58	0.0027
Peripheral tip colonisation (yes/overall)	27/106	5/104	<0.0001
Peripheral insertion site colonisation (yes/no)	51/109	9/104	<0.0001
Unplanned removal of epidural catheter (yes/no)	9/59	16/60	0.18
Unplanned removal of peripheral catheter (yes/no)	31/96	32/104	0.88
