Although red blood cell transfusion has been associated with an increase in early morbid outcomes and reduced long-term survival after cardiac surgery, its relationship to functional quality of life after surgery has not been previously explored. Our objective was to investigate the relationship between perioperative red blood cell and component transfusion and functional health-related quality of life 6 to 12 months after cardiac surgery.
Of 12,536 patients undergoing cardiac surgical procedures between May 1995 and January 1999, 7,321 completed a self-administered Duke Activity Status Index (DASI) survey preoperatively and least one follow-up survey at nominally 6 or 12 months postoperatively. The influence of baseline DASI, preoperative risk factors, clinical status, laboratory values, operative events, and postoperative morbidities on follow-up DASI were examined with ordinal regression modeling.
After adjustment for preoperative DASI, demographic, cardiac and noncardiac comorbidity, type of surgery, postoperative complications, and interval between follow-up DASI, during which patients continued to improve (p < 0.0001), postoperative functional status after cardiac surgery was incrementally worse the more perioperative red cells (p < 0.0001) and platelets (p = 0.02) that had been transfused.
Red blood cell and platelet transfusion have an unintended persistently negative risk-adjusted effect on health-related quality of life after cardiac surgery that extends well beyond initial hospitalization. Reductions in functional recovery paralleled increasing units of red blood cells transfused.

    • "Even 1 year mortality was significantly lower in patients given newer blood (7.4% vs 11.0%, p<0.001) [10]. Furthermore, Koch et al. published three other studies showing the negative effect of RBC transfusion [4, 9, 11]. Summarizing these studies, data showed that transfusion of RBCs was associated with a risk-adjusted reduction in survival for “early” (defined as until 6 months postoperatively, p<0.0001) and “late” (defined as about 10 years, p<0.0001) phases [9].

    ABSTRACT: To identify the impact of storage time and amount of transfused red blood cell units on renal function. Consecutive transfused patients (n=492), undergoing cardiac surgery at a single centre and receiving at least one red blood cell unit, were pooled in different groups depending on storage time and amount of transfusion. Altogether 2,133 red blood cell units were transfused (mean age 21.87 days). Pre- and intraoperative data were similar between groups. Postoperative serum creatinine (p<0.01), glomerular filtration rate (p<0.01), and urea (p<0.01) showed a significant correlation with the amount of transfused red blood cell units, but not with storage time. Acute kidney insufficiency (creatinine values greater than 2.0 mg/dl or a duplication of the preoperative value) developed in 29% of patients and was associated with red blood cell mean age (p=0.042), absolute age (p=0.028), and amount of transfused (p<0.01) units. Acute kidney failure requiring renal replacement therapy occurred in 9.6% of patients and was associated with the amount of transfusion (p<0.01). Worsening of renal function after cardiac surgery is associated with storage time and amount of transfused red blood cell units. Acute kidney insufficiency was defined as serum creatinine values greater than 2.0 mg/dl or a duplication of the preoperative value (baseline). Acute kidney failure was defined as becoming dependent upon dialysis.

    • "Our results showed that the EHH group showed significantly less blood loss and transfusion requirements than the control group by amount of 32.5% (57.5% versus 25%). Recently, transfusion seems to be more harmful than previously believed [21,22]. However, in our study, the two groups' mean postoperative blood losses, which were determined using Hemovac quantities at 24 and 48 hours after surgery, were not different This fact suggests that the effect of hypothermia on the bleeding is temporary and reversible.

    ABSTRACT: General anesthesia often produces some degree of hypothermia and hypothermia causes much more blood loss during surgery than normothermia. Electrically heated humidifiers (EHHs) have been used for patients under general anesthesia and in the intensive care unit. However, the benefits of the EHH have not been widely reported in the literature. Patients scheduled for posterior lumbar spine fusion, were randomly assigned to a mechanically ventilated with EHH circuit group or to a conventional respiratory circuit group. Their tympanic membrane temperature was monitored every 30 min after induction up to 180 min, and perioperative blood losses, transfusion requirements during surgery, and other complications were noted. Patients in the control group (n = 40) showed a lower mean body temperature at all times than immediately after induction, while the EHH group (n = 40) showed a lower body temperature from 60 minute after induction comparing to the initial temperature. Furthermore, patients in the EHH group had a higher mean body temperature than patients in the control group during surgery (35.9 ± 0.4 vs 35.4 ± 0.5, P < 0.001). Mean intraoperative blood loss (9.75 ± 5.4 vs 7.48 ± 3.9, P = 0.035) and transfusion requirements (57.5% vs 25%, P = 0.006) were significantly less in the EHH group, but postoperative blood loss, duration of hospitalization, and other complications were not significantly different in the two study groups. The use of an electrically heated humidifier did not prevent a body temperature drop under general anesthesia. However, it helped maintain body temperature and was associated less blood loss and transfusion requirement during surgery.

    • ". Platelet transfusion per se in the perioperative period has been associated with an increased risk of serious adverse events [2]. Both red cell and platelet transfusion have been shown to have a negative risk-adjusted effect on health-related quality of life after cardiac surgery [3]. The pathogenesis of coagulopathy and platelet dysfunction in this patient group is multifactorial: patients presenting for elective cardiac surgery are getting older and more complex. "

    ABSTRACT: Allogenic blood transfusion may affect clinical outcomes negatively. Up to 20% of blood transfusions in the United States are associated with cardiac surgery and so strategies to conserve usage are of importance. This study compares administration according to physician's choice based on laboratory coagulation tests with application of a strict protocol based on the thromboelastograph (TEG). Sixty-nine patients presenting for cardiac surgery were randomised to either study or control groups. In the study group a strict protocol was followed covering usage of all blood products according to TEG patterns. In the control group, the physician directed product administration with reference to activated partial thromboplastin time (APTT), international normalised ratio (INR), fibrinogen and platelet count. Bleeding, re-sternotomy, minimum haemoglobin, intubation time, and ICU stay were documented. TEG-based management reduced total product usage by 58.8% in the study group but this was not statistically significant. This was associated with a statistically insignificant trend towards better short-term outcomes. This pilot study suggests that a strict protocol for blood product replacement based on the TEG might be highly effective in reducing usage without impairing short-term outcome.
