Randomized Controlled Trial Comparative Study
Randomized comparison of closed-loop feedback computer-controlled with manual-controlled infusion of phenylephrine for maintaining arterial pressure during spinal anaesthesia for caesarean delivery.
Closed-loop feedback computer-controlled infusion has not been described for administering phenylephrine to maintain arterial pressure (AP) during spinal anaesthesia for caesarean delivery. We aimed to compare AP control using this automated system with a previously described manual infusion system. ⋯ Within the constraints of the studied algorithms, closed-loop feedback computer-controlled phenylephrine infusion provided better AP control with fewer interventions required compared with manual-controlled infusion.

Convulsive seizures (CS) occur in ∼1% of the patients after cardiac surgery with cardiopulmonary bypass. Recent investigations indicate an up to seven-fold increase in CS in cardiac surgical patients receiving high doses (≥60 mg kg(-1) body weight) of tranexamic acid (TA). ⋯ In open-heart surgery, even moderate TA doses are associated with a doubled rate of CS and in-hospital mortality. Prospective trials are needed to further evaluate the safety profile of TA in cardiac surgery.

Current thinking about patient safety emphasizes the relationship between organizational factors, that is, latent risk factors (LRFs) and patient safety. This study explores the influence of the operating theatre (OT), intensive care unit (ICU), and disciplines on ratings of LRFs. If we have an understanding of the contribution made by these factors, we can identify significant points from which we can promote a safe environment. ⋯ As healthcare focuses its safety efforts towards system issues rather than towards the individual provider of care, attention has turned to organizational factors, known as LRFs. Understanding how LRFs affect safety should enable us to design more effective measures that will improve overall safety. Strategies for improving patient safety should be tailored specifically for various clinical areas and disciplines.
