Preoperative anaemia is common in patients undergoing orthopaedic and other major surgery. Anaemia is associated with increased risks of postoperative mortality and morbidity, infectious complications, prolonged hospitalization, and a greater likelihood of allogeneic red blood cell (RBC) transfusion. Evidence of the clinical and economic disadvantages of RBC transfusion in treating perioperative anaemia has prompted recommendations for its restriction and a growing interest in approaches that rely on patients' own (rather than donor) blood. These approaches are collectively termed 'patient blood management' (PBM). PBM involves the use of multidisciplinary, multimodal, individualized strategies to minimize RBC transfusion with the ultimate goal of improving patient outcomes. PBM relies on approaches (pillars) that detect and treat perioperative anaemia and reduce surgical blood loss and perioperative coagulopathy to harness and optimize physiological tolerance of anaemia. After the recent resolution 63.12 of the World Health Assembly, the implementation of PBM is encouraged in all WHO member states. This new standard of care is now established in some centres in the USA and Austria, in Western Australia, and nationally in the Netherlands. However, there is a pressing need for European healthcare providers to integrate PBM strategies into routine care for patients undergoing orthopaedic and other types of surgery in order to reduce the use of unnecessary transfusions and improve the quality of care. After reviewing current PBM practices in Europe, this article offers recommendations supporting its wider implementation, focusing on anaemia management, the first of the three pillars of PBM.
Since 2005, 11 human face transplants have been performed. In each, varying amounts of tissue have been transplanted. Herein we report a "full" face transplant including all intact aesthetic and functional units. On March 27, 2010, we performed a full face transplant, including all the soft tissues and part of the underlaying bony structure, at the University Hospital Vall d'Hebron, Barcelona, Spain. The donor was a 41-year-old male, who died from a massive brain hemorrhage. The recipient was a 30-year-old male with a severe facial deformity caused by a ballistic trauma in 2005. Harvest and subsequent implant took 24 hours. The patient received initial induction (Thymoglobulin 2 mg/kg/iv; Prednisone 1 gm/iv) and maintenance (Prednisone 1 mg/kg/24hours, Tacrolimus 10-15 ng/mL/PO, and Mycophenolate mofetil 2g/daily/PO) immunosuppression and Infection prophylaxis (Valganciclovir and Co-trimoxazole). There were no intraoperative complications. Postoperative complications included; venous anastomoses thrombosis, acute oro-cutaneous fistula, right parotid sialocele and 2 acute rejection episodes, which were resolved by revision of the anastomosis, profuse irrigation and immunotherapy adjustment, respectively. The patient was discharged from the hospital at 4 months posttransplant with; near-total sensation and partial-motor recovery, no psychological complications and excellent acceptance of his new facial appearance. The early success described in this case report demonstrates the technical and clinical feasibility of transplanting all the tissues of the with all its aesthetic and functional units intact.
Adolescent idiopathic scoliosis (AIS) can lead to ventilatory restriction, respiratory muscle weakness and exercise limitation. However, both the causes and the extent of muscle dysfunction remain unclear. The aim of our study is to describe muscle weakness and its relationship to lung function and tolerance to exercise in AIS patients.Lung and muscle function, together with exercise capacity, were assessed in 60 patients with pronounced spinal deformity (>40°) and in 25 healthy volunteers.Patients with AIS had only mild to moderate abnormal ventilatory patterns, the most frequent of which were restrictive abnormalities. The function of respiratory and limb muscles and exercise capacity were below normal limits in AIS patients, and were significantly lower than in controls. Exercise capacity was found to correlate with the function of inspiratory, expiratory, upper limb and lower limb muscles which, in addition, were reciprocally interrelated. Multivariate analysis showed that lower limb muscle function is the main contributor to exercise intolerance. There appeared to be no connection between spinal deformity and lung function, muscle function or exercise capacity.We conclude that AIS patients show generalised muscle dysfunction which contributes to the reduction in their exercise capacity, even in the absence of severe ventilatory impairment.
Since 1968, when Baxter and Shires developed the Parkland formula, little progress has been made in the field of fluid therapy for burn resuscitation, despite advances in haemodynamic monitoring, establishment of the ‘goal-directed therapy’ concept, and the development of new colloid and crystalloid solutions. Burn patients receive a larger amount of fluids in the first hours than any other trauma patients. Initial resuscitation is based on crystalloids because of the increased capillary permeability occurring during the first 24 h. After that time, some colloids, but not all, are accepted. Since the emergence of the Pharmacovigilance Risk Assessment Committee alert from the European Medicines Agency concerning hydroxyethyl starches, solutions containing this component are not recommended for burns. But the question is: what do we really know about fluid resuscitation in burns? To provide an answer, we carried out a non-systematic review to clarify how to quantify the amount of fluids needed, what the current evidence says about the available solutions, and which solution is the most appropriate for burn patients based on the available knowledge.

Background. Perioperative tranexamic acid (TXA) use can reduce bleeding and transfusion requirements in several types of surgery, but level I evidence proving its effectiveness in major spine surgery is lacking. This study was designed to investigate the hypothesis that TXA reduces perioperative blood loss and transfusion requirements in patients undergoing major spine procedures. Methods. We conducted a multicentre, prospective, randomized double-blind clinical trial, comparing TXA with placebo in posterior instrumented spine surgery. Efficacy was determined based on the total number of blood units transfused and the perioperative blood loss. Other variables such as the characteristics of surgery, length of hospital stay, and complications were also analysed. Results. Ninety-five patients undergoing posterior instrumented spine surgery (fusion of >3 segments) were enrolled and randomized: 44 received TXA (TXA group) and 51 received placebo (controls). The groups were comparable for duration of surgery, number of levels fused, and length of hospitalization. Transfusion was not required in 48% of subjects receiving TXA compared with 33% of controls (P = 0.05). Mean number of blood units transfused was 0.85 in the TXA group and 1.42 with placebo (P = 0.06). TXA resulted in a significant decrease in intraoperative bleeding (P = 0.01) and total bleeding (P = 0.01) relative to placebo. The incidence of adverse events was similar in the two groups. Conclusions. TXA did not significantly reduce transfusion requirements, but significantly reduced perioperative blood loss in adults undergoing major spinal surgery. Clinical trial registration. NCT01136590.

Tranexamic acid (TXA) significantly reduces blood loss in a wide range of surgical procedures and improves survival rates in obstetric and trauma patients with severe bleeding. Although it mainly acts as a fibrinolysis inhibitor, it also has an anti-inflammatory effect, and may help attenuate the systemic inflammatory response syndrome found in some cardiac surgery patients. However, the administration of high doses of TXA has been associated with seizures and other adverse effects that increase the cost of care, and the administration of TXA to reduce perioperative bleeding needs to be standardized.
