The aim of this study was to assess knowledge, attitudes, and proficiency in relation to organ donation among staff members of intensive care units (ICUs) in donor hospitals, and possibly identify areas for improvement. The investigation was carried out as a collaboration between the transplant center and appointed key persons in all 17 ICUs in 15 hospitals in northern Denmark. A total of 1168 structured questionnaires were distributed to the health care professionals in the ICUs in the region; 689 were returned, giving a response rate of 59%. ⋯ Further, the survey demonstrates as expected a significant lack of experience in organ donation. Our data show a considerable need for more education and training, especially on how to inform and support the donor relatives and how to identify potential donors. The survey also discloses a substantial need for information regarding the results of transplantation.

The results of solid organ transplantation have improved during the last decade. Five-year patient survivals over 80% and graft survivals over 70% are common in many transplant centers. Also, quality-of-life assessments show that not only adults but even small children have a good quality of life after successful organ transplantation. ⋯ To improve cadaveric organ procurement the Donor Action (DA) program, which consists of a Hospital Attitude Survey and a medical records review performed by the donor hospital, has proved to increase the number of cadaveric donors. We introduced the DA program in Finland in 2000. Here in we report the results of this program in terms of its impact on the availability of cadaveric donors.

Cytomegalovirus (CMV) infection after solid organ transplantation is one of the most common viral infections, causing significant morbidity and mortality if not treated promptly. Ganciclovir has proven to be effective for the prophylaxis and treatment of CMV. However, oral absorption of ganciclovir is poor. Recently, oral administration of valganciclovir hydrochloride (Valcyte) has been observed to display 10-fold better absorption than oral ganciclovir. Valganciclovir has increasingly been used as prophylaxis against CMV after solid organ transplantation. The purpose of this study was to examine the efficacy of valganciclovir prophylaxis therapy after primary liver transplantation. ⋯ Valganciclovir failed to provide adequate prophylaxis following liver transplantation in our patients. The overall rate of CMV in seropositive donors and/or recipients was 17%, and in the high-risk group was 26%. Further prospective studies with measurement of ganciclovir concentrations are needed to elucidate the reasons for this unexpected failure.

Comparative Study Clinical Trial Controlled Clinical Trial
Internal jugular versus subclavian vein catheterization for central venous catheterization in orthotopic liver transplantation.
The aim of this study was to compare incidence rates of mechanical and infectious complications associated with central venous catheterization via the internal jugular vein (IJV) versus the subclavian vein (SV) among 45 consecutive patients undergoing orthotopic liver transplantation (OLT) between January 2000 and June 2004. The subjects were divided into two groups according to the site of central venous catheterization (IJV or SV). We recorded each patient's physical characteristics, international normalized ratio (INR), partial thromboplastin time, platelet levels, number of puncture attempts, success/failure of central venous catheterization, duration of catheter placement, occurrence of catheter tip misplacement, arterial puncture, incidence of hematoma or pneumothorax, catheter-related infection, or bacterial colonization of the catheter. ⋯ Both groups showed high frequencies of catheter tip misplacement, with right atrium as the site of misplacement in all cases. Two patients in the IJV group (8.7%) developed hematomas after accidental carotid artery puncture. The results suggest that, when performed by experienced anesthesiologists, central venous catheterization via the SV is an acceptable alternative to IJV catheterization for patients undergoing OLT.

Anesthetic management of orthotopic liver transplantation (OLT) in pediatric patients is challenging in terms of intraoperative bleeding, fluid management, and hemodynamic monitoring. The pulse contour cardiac output (PiCCO) system, a relatively new device based on the single-indicator transaortic thermodilution technique, may be useful for intraoperative hemodynamic monitoring in pediatric patients. This is a preliminary report of PiCCO use in nine children (aged 9.8 +/- 4.7 years) undergoing OLT. ⋯ There were no PiCCO catheter-related complications in any patient. These findings demonstrate that the PiCCO system is a safe, continuous, multiparameter invasive monitoring device for use in pediatric patients undergoing OLT. This system may provide valuable data during pediatric OLT and appears to be a promising monitoring tool in these patients.
