Comparative Study[Risk factors for transfusion in primary knee arthroplasty].
Transfusion is becoming safer but is not free of risk. It is important to establish a good approach to transfusion management and calculate real losses. Risk factors for transfusion should be identified. ⋯ Initial Hb, which can be modified before surgery, is one of the factors that most affects whether or not the patient will need a transfusion. Therefore, one of our first objectives in the process of managing transfusion is to improve preoperative Hb values.

Review[Jehovah's Witnesses refusal of blood: religious, legal and ethical aspects and considerations for anesthetic management].
The refusal of Jehovah's Witnesses to agree to blood or blood product transfusion based on religious beliefs is one of the most challenging conflictive issues health care givers have to face today. Such conflict is a by product of the ideological and religious diversity in society today. The perioperative care of such patients constitutes a genuine challenge for anesthesiologists and surgeons from technical, scientific, ethical, and legal perspectives. ⋯ The literature up to August 2005 was reviewed by MEDLINE search. The following search terms were used: Jehovah's Witnesses, anesthesia (and anaesthesia), legislation and jurisprudence, ethics, blood transfusion, alternatives, anemia (and anaemia), erythropoietin, trigger, and critical care. To further cover ethical and legal aspects, we reviewed current laws in Spain and similar practice settings.

[Relation between glucose concentrations in cerebrospinal fluid and sensory and motor block during spinal anesthesia with hyperbaric bupivacaine].
To study the relation between cerebrospinal fluid (CSF) glucose levels, the highest level of sensory block, and the duration of motor block after intrathecal injection of 2 mL of hyperbaric bupivacaine. To determine CSF glucose levels upon recovery from motor block. ⋯ After continuous spinal anesthesia with hyperbaric bupivacaine, glucose concentrations in CSF are directly related to the highest level of sensory block, the course of the blockade, and its reversal.

Case Reports[Cerebrospinal fluid drainage in endovascular repair of thoracic aortic lesions: preliminary report of experience with 5 patients].
Endovascular repair of thoracic or thoracoabdominal aortic lesions as an alternative to open surgery, to avoid the high complication and mortality rates associated with the conventional approach, does not eliminate the risk of postoperative paraplegia. We report on a series of 5 patients with different thoracic aortic lesions who underwent endovascular stent-graft repair procedures. We describe measures to drain cerebrospinal fluid to prevent ischemic spinal cord injury. We also review the anesthetic management of patients undergoing this type of surgery.

Clinical Trial[Usefulness of transesophageal echocardiography during myocardial revascularization surgery without extracorporeal circulation].
Intraoperative transesophageal echocardiography can be a highly useful monitoring technique during myocardial revascularization surgery when extracorporeal circulation (ECC) is not being used. Transesophageal echocardiography provides real-time images on both volume status and segmental myocardial contractility without interfering with the surgical field. ⋯ Transesophageal electrocardiography is a minimally invasive, safe, and precise way to directly monitor the beating heart in real time during myocardial revascularization without ECC. Image quality is good.
