Parenteral analgesics are still diffusely administered for postoperative pain after major liver resection, while epidural analgesia is widely criticized because of possible changes in the postoperative coagulation profile. The safety of regional anesthesia in liver resections is based on appropriate timing of needle placement and catheter removal and on the individual's skill in performing both the puncture and the catheterization. In the absence of liver failure or in cases of only moderate hepatic dysfunction, the risk of neurologic complications and spinal hematomas does not appear greater than when an epidural is performed for routine abdominal or thoracic surgery. ⋯ However, a low CVP may not be tolerated by all patients: intraoperative hemodynamic instability may, in fact, easily ensue because of the cardiovascular depressant effects of anesthetics, surgical blood losses, and manipulation of the inferior vena cava. We suggest combining intraoperative epidural anesthesia with general (light) anesthesia as a useful strategy to keep the CVP low during liver resection without vasodilators or diuretics. Epidural anesthesia does not lead to changes in intravascular volume, but only promotes redistribution of blood, decreasing both venous return and portal vein pressure, thus contributing to reduced hepatic congestion and surgical blood loss.

A patient undergoing renal transplantation presents unique problems to the anesthetist, as almost every body system is affected. The combined spinal-epidural technique has become popular in lower abdominal surgeries because it offers the advantages of both spinal and epidural techniques. We review our experience of combined spinal-epidural technique in patients undergoing renal transplantation with respect to demographics, intraoperative anesthesia, hemodynamics, postoperative analgesia, and untoward adverse events. ⋯ Combined spinal-epidural anesthesia proved to be a useful regional anesthetic technique, combining the reliability of spinal block and versatility of epidural block for renal transplantation.

Although the contraindications for thoracic epidural anesthesia (TEA) are well defined, the debate continues about whether TEA improves outcomes. Pro and con trials and a metaanalysis in the past have yielded equivocal results; they did not deal with new vascular intervention or drugs. The benefit of TEA in surgery is to provide analgesia. ⋯ TEA suitability is based on an evaluation of the contraindications, comorbidities, coagulation profiles, hepatic reserve, and balance of benefits and risks. The insertion or withdrawal of the epidural catheter should be made with care according to the neuroaxial guidelines and in the presence of a normal TEG. The decreasing level of prothrombin content and platelet counts after hepatectomy should be closely monitored every 2 to 5 days.

Pancreatic carcinoma, an important leading cause of cancer death, has increased steadily in incidence and still has a poor prognosis. Pain is one of the most frequent symptoms, affecting more than 75% of patients. It is often present in the early stages of disease and may be severe and difficult to treat. ⋯ Thus, painful tumors in these viscera may have pain relieved through the use of a neurolytic celiac plexus block (NCPB). Although some investigators questioned the role and the efficacy of NCPB in the treatment of upper abdominal cancer pain, most of them have suggested that it may represent the optimal treatment, especially for pancreatic cancer pain. In this report we have reviewed the techniques, results, and complications of NCPB for the treatment of pancreatic cancer pain.

The family advocate plays a crucial role in the organ and tissue procurement process for transplantation and research. This responsibility can weigh profoundly on the consent/conversion rates for family advocates. Some potential donor families consider time as a critical factor when deciding to donate. It was hypothesized that case time will decrease by >or=20% if family advocates were trained to become level 1 recovery coordinators and utilized during organ only cases with brain-dead donors. ⋯ The results indicate that family advocates who can function in the role of level 1 recovery coordinators may decrease donor management by hours. Incorporating family services with donor management can improve the standard in the donation process.
