A closed loop computer system has been developed to deliver sodium nitroprusside (by infusion) to control systolic arterial pressure (SAP) after cardiopulmonary bypass. The performance of the closed-loop control system was evaluated by comparing nurse and computer control of SAP in 60 patients during the early postoperative period. The computer system provided better control of SAP than manual control by a member of the nursing staff.
Tighter glycemic control goals can be attained in a busy ICU by a nurse-led team using a pathway for identifying and treating hyperglycemia, clear decision support tools, and adequate nurse education. The novel chart-based insulin infusion algorithm chosen as the standard for this pilot was an effective tool for reducing the blood glucose to target range with no clinically significant hypoglycemia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
