Anaesthesia

Sugammadex is a drug used to reverse neuromuscular blockade induced by rocuronium or vecuronium. It has not yet been approved by the Food and Drug Administration in the USA due to concerns regarding hypersensitivity. The objective of this review was to identify similarities in the presentation of hypersensitivity reactions to sugammadex. ⋯ All cases that reported exact timing (14/15) occurred in 4 min or less. Most of the patients (11/15; 73%) met World Anaphylaxis Organization criteria for anaphylaxis. Awareness must be raised for the possibility of drug-induced hypersensitivity during the critical 5-min period immediately following sugammadex administration.

Randomized Controlled Trial Comparative Study
The effect of continuous popliteal sciatic nerve block on unplanned postoperative visits and readmissions after foot surgery - a randomised, controlled study comparing day-care and inpatient management.
Regional anaesthesia has been shown to have several advantages over general anaesthesia in reducing the need for, and hence cost of, unscheduled outpatient visits or readmission to hospital. However, the benefit has not been evaluated in a direct comparison between day-care patients and inpatients. We randomly allocated 120 patients undergoing unilateral foot surgery to either inpatient (two-day postoperative stay) or day-care management under continuous regional anaesthesia, and compared the impact on unscheduled postoperative outpatient visits, readmissions to hospital and the associated costs. ⋯ We found no significant difference in the incidence of outpatient visits (3.3% day-care vs 5.0% inpatient, p = 0.640), readmissions (6.7% day-care vs 3.3% inpatient, p = 0.395) or complications between the two groups. Costs were also significantly lower in the day-care group (net difference €8011 (£6684; $10 986) per patient, p < 0.001). We conclude that continuous regional anaesthesia allows foot surgery to be performed as a day-care procedure more cheaply than in inpatients, without an increase in clinical complications.

Concise guidelines are presented that recommend the method of choice for skin antisepsis before central neuraxial blockade. The Working Party specifically considered the concentration of antiseptic agent to use and its method of application. The advice presented is based on previously published guidelines, laboratory and clinical studies, case reports, and on the known properties of antiseptic agents.

We investigated the utility of a cell-saver device for processing out-of-date red blood cells, by washing twenty bags of red blood cells that had been stored for between 36 and 55 days. The volume of recovered cells, and the characteristics of the suspension fluid, were measured before and after treatment. The ratio of free haemoglobin to total haemoglobin was up to 0.02 before processing, and up to 0.011 afterwards, changing by between -0.013 and +0.003. ⋯ Lactate ion concentration fell to a mean value of 14 mmol.l(-1) (p < 0.001). Sodium ion concentration rose from a mean value of 93 mmol.l(-1) to a mean value of 140 mmol.l(-1) (p < 0.001). A useful proportion of out-of-date red blood cells remained intact after conditioning using a cell-saver, and the process lowered concentrations of potentially toxic solutes in the fluid in which they were suspended.
