Randomized Controlled Trial
Does motor block related to long-acting brachial plexus block cause patient dissatisfaction after minor wrist and hand surgery? A randomized observer-blinded trial.
Patient dissatisfaction has been previously associated with motor block in shoulder surgery patients receiving brachial plexus block. For elective minor wrist and hand surgery, we tested whether a regional block accelerating the early return of upper extremity motor function would improve patient satisfaction compared with a long-acting proximal brachial plexus block. ⋯ Patient satisfaction is not improved after elective minor wrist and hand surgery with a regional block accelerating the early return of motor function. For this surgery, motor block related to a long-acting brachial plexus block does not appear to cause patient dissatisfaction. Clinical Trial Registration number. ACTRN12610000749000, https://www.anzctr.org.au/registry/trial_review.aspx?ID=335931.

Target controlled infusion (TCI) with sufentanil is usually performed using the Gepts model, which was derived from patients undergoing general surgery. It is, however, known that pharmacokinetics of sufentanil can be changed during cardiopulmonary bypass (CPB). We tested whether TCI during coronary artery bypass surgery with CPB produces constant total, unbound sufentanil concentration-time course or both. ⋯ Neither total nor unbound sufentanil concentrations remained constant when performing a TCI with the Gepts model in coronary artery bypass surgery with CPB. A pharmacokinetic model derived from patients undergoing cardiac surgery with CPB might improve the performance of TCI in this population.

Distractions are a potential threat to patient safety. Previous research has focused on parts of the anaesthetic process but not on entire cases, and has focused on hazards rather than existing defences against error ⋯ Distractions are common in anaesthetic practice and managing them is a key professional skill which appears to be part of the tacit knowledge of anaesthesia. Anaesthetists should also bear in mind that the potential for distraction is mutual and reciprocal and their actions can also threaten safety by interrupting other theatre staff.
