Transmission of parasitic and bacterial infections through blood transfusion within the U.S.

Abstract: The American public has become aware that viral infections can be transmitted by blood transfusions; however, less attention has been paid to nonviral agents that are similarly transmitted. Although donors are tested routinely for serologic evidence of Treponema pallidum infection (syphilis), there are no other bacterial infections for which donors are routinely tested, and no testing is done routinely to detect parasitic infections. Although current preventive strategies appear effective in preventing the transmission of nonviral agents by transfusion, changing population demographics, increased travel and immigration, and increased occurrence of certain asymptomatic bacterial infections in blood donors may require new policies to maintain the safety of the U.S. blood supply. This review focuses on the parasitic and bacterial infections that might pose a risk to transfusion recipients in the U.S.

Comprehensive pharmaceutical services in a medical intensive-care unit.

Abstract: The clinical and distributive services that have been provided by clinical pharmacists for the past 14 years in the medical intensive care unit (MICU) of a 1600-bed urban teaching hospital are described. The MICU pharmacy staff consists of 4.3 full-time equivalent pharmacists who provide daily 24-hour services. The pharmacists are actively involved in all pharmacological decisions with hands-on control of drug distribution from preparation through delivery and administration. They maintain up-to-date patient medication records and monitoring flow sheets for each patients. The pharmacists identify adverse reactions, formulate contingency plans, and promptly intervene to prevent crises. They provide comprehensive pharmacokinetic services, select drug administration times and routes, and prepare and deliver all medications. All i.v. medications are custom-made to meet the patients' fluid, sodium, or potassium restrictions. The pharmacists set up infusion pumps and select the proper infusion rates for i.v. and intra-arterial drugs. They also recommend and monitor the patients' nutritional support therapy. The program has been well accepted by nurses and physicians; however, only 20% of the inpatient clinical pharmacists desire to work in the MICU. The skills and educational requirements for managing patients in an MICU are discussed. Pharmacists have become an integral part of this MICU by optimal drug therapy, increasing productivity and efficiency, providing prompt and accurate services, and participating in research.

Balanced blood product transfusion during liver transplantation.

Abstract: INTRODUCTION This study was conducted to determine whether an intra-operative ratio of at least 1:1:2 of fresh frozen plasma (FFP):platelets (PLTs):packed red blood cells (pRBCs) improves outcomes in orthotopic liver transplantation (OLT). METHODS A single-center, retrospective study of deceased donor OLT recipients (MELD ≥15) requiring intra-operative pRBC transfusion (years 2013-2016). Patients were grouped into those receiving an intra-operative ratio of ≥1:1:2 of FFP:PLTs:pRBCs vs ratios .05). Patients in the ≥1:1:2 group had lower pRBC and intra-operative blood product requirements (11 ± 0.5 vs 19 ± 1.4 units, P < .001, and 33 ± 1.3 vs 43 ± 3.3 units, P = .006, respectively), improved 1-month mortality (0 vs 8%, P = .002), improved 1-year survival (P = .004), less intra-operative cardiac arrest (3% vs 10%, P = .03), and shorter operating room time (389 ± 7.2 vs 431 ± 17.2 minutes, P = .03). After multivariate adjustment for baseline and intra-operative variables, balanced blood product transfusion (BBPT) was significantly associated with less intra-operative pRBC transfusion (95% confidence interval: 0.60-0.72). CONCLUSION Balanced blood product transfusion is associated with reduced transfusion requirements in OLT.
