Is There an Advantage to Knotless Barbed Suture in TKA Wound Closure?
In this randomized controlled trial, I found knotless bidirectional barbed suture to be more efficient in terms of closure time and lower in direct operative cost than conventional suture material, while showing no difference in terms of Knee Society knee scores, ROM, or wound appearance with the numbers available. Future studies with larger numbers will be needed to compare overall costs of care and to detect uncommon complications that might arise, although none were observed in this small series.
Documentation of point-of-care blood glucose measurement errors likely overestimates ICU hypoglycaemia rates and can be reduced by a quality improvement effort. The currently used hypoglycaemic patient-day metric does not evaluate recurrent or prolonged events that may be more likely to cause patient harm. The monitored patient-day as currently defined may not be the optimal denominator to determine inpatient hypoglycaemic risk.
