Blood management protocols attempt to reduce blood loss by strategies including autologous blood donation, red cell salvage, normovolaemic haemodilution and haemostatic agents such as tranexamic acid (TXA). TXA usage in particular has become increasingly commonplace with numerous studies demonstrating a significant reduction in peri-operative blood loss and proportion of patients requiring transfusion, without increasing the risk of venous thromboembolism.
Aims. Glucose-insulin-potassium (GIK) is protective following cardiac myocyte ischaemia-reperfusion (IR) injury, however the role of GIK in protecting skeletal muscle from IR injury has not been evaluated. Given the similar mechanisms by which cardiac and skeletal muscle sustain an IR injury, we hypothesized that GIK would similarly protect skeletal muscle viability. Methods. A total of 20 C57BL/6 male mice (10 control, 10 GIK) sustained a hindlimb IR injury using a 2.5-hour rubber band

Background. Tourniquets are routinely used in total knee arthroplasty (TKA) with an estimated use by up to 93% of surgeons. Advantages include the ability to provide a bloodless field of view to facilitate cement application and increase the success of the procedure. Overall reduction in blood loss is another perceived advantage, however recent research has demonstrated no measurable reduction and conversely a substantial increase in complications such as deep vein thrombosis and systemic emboli.

Background. Tourniquets and tranexamic acid (TXA) are commonly used in total knee arthroplasty (TKA), but there is not consensus on how these interventions affect blood transfusion rates and total blood loss. Few studies examine the combined use of both interventions. We compared outcome measures and transfusion rates following TKA, with and without the use of

This study aims to determine the incidence of surgical site infection leading to reoperation for sepsis following minor hand procedures performed outside the main operating room using field sterility in the South African setting. The investigators retrospectively reviewed the records of 485 patients who had WALANT-assisted minor hand surgery outside a main operating theatre, a field sterility setting between March 2019 and April 2023. The primary outcome was the presence or absence of deep surgical site infection that required reoperation within four weeks. Cases included where elective WALANT minor hand procedures, a minimum age of 18 with complete clinical records. The patients were mostly female (54.8%), with a mean age of 56.35 years. The majority of cases were trigger finger and carpal tunnel release. An overall 485 cases were reviewed, the deep surgical site infection rate resulting in reoperation within 4 weeks post-operatively was 1.24% ((95% Confidence Interval (CI) 0.0034 to 0.0237); p = 0.009). Minor hand procedures performed under field sterility using WALANT have a low surgical site infection rate. The current study's infection rates are comparable to international surgical site infection rates for similar surgeries performed in main operating rooms using standard sterilisation procedures. Field sterility is a safe and acceptable clinical practice that may improve work efficiency in public sector.
