The effects of storage of red blood cells on the development of postoperative infections after noncardiac surgery.

BACKGROUND: Prolonged storage of red blood cells (RBCs) is a potential risk factor for postoperative infections. The objective of this study was to examine the effect of age of RBCs transfused on development of postoperative infection. STUDY DESIGN AND METHODS: In this prospective, double-blind randomized trial, 199 patients undergoing elective noncardiac surgery and requiring RBC transfusion were assigned to receive nonleukoreduced RBCs stored for not more than 14 days ("fresh blood" group, n = 101) or for more than 14 days ("old blood" group, n = 98). The primary outcome was occurrence of infection within 28 days after surgery; secondary outcomes were postoperative acute kidney injury (AKI), in-hospital and 90-day mortality, admission to intensive care unit, and hospital length of stay (LOS). As older blood was not always available, an "as-treated" (AT) analysis was also performed according to actual age of the RBCs transfused. RESULTS: The median [interquartile range] storage time of RBCs was 6 [5-10] and 15 [11-20] days in fresh blood and in old blood groups, respectively. The occurrence of postoperative infection did not differ between groups (fresh blood 22% vs. old blood 25%; relative risk [RR], 1.17; confidence interval [CI], 0.71-1.93), although wound infections occurred more frequently in old blood (15% vs. 5%; RR, 3.09; CI, 1.17- 8.18). Patients receiving older units had a higher rate of AKI (24% vs. 6%; p < 0.001) and, according to AT analysis, longer LOS (mean difference, 3.6 days; CI, 0.6-7.5). CONCLUSION: Prolonged RBC storage time did not increase the risk of postoperative infection. However, old blood transfusion increased wound infections rate and incidence of AKI.

Impact of Genetic Counseling in Women with a Family History of Breast Cancer in Italy.

As the impact of breast cancer (BC) risk assessment in asymptomatic women with a family history of BC had never been explored in Italy, we performed a study on a retrospective series of women who had undergone BC risk assessment. To this aim, a semi-structured telephone interview was administered to 82 women. Most participants considered the information received as clear (96.2 %) and helpful (76.8 %). Thirty-eight (46.3 %) stated that their perceived risk of BC had changed after the counseling: for 40.2 % it had decreased, for 6.1 % increased; however, women highly overestimating their risk at the baseline (≥ 4-fold) failed to show improvements in risk perception accuracy. Sixty-six women (80.5 %) stated they had followed the recommended surveillance, while 19.5 % had not, mainly due to difficulties in arranging examinations. Most women (89.0 %) had shared the information with their relatives, with 57.3 % reporting other family members had undertaken the recommended surveillance. BC risk assessment was associated with high rates of satisfaction and had a favorable impact on risk perception in a subgroup of women. The impact on surveillance adhesion extended to relatives. Organized programs for identification and surveillance may help identify a larger fraction of at-risk women and overcome the reported difficulties in arranging surveillance.

Our paper 20 years later: 1-year survival and 6-month quality of life after intensive care.

INTRODUCTION: In the early 1990s, the in-hospital mortality rate of intensive care unit (ICU) patients dropped, and interest in the quality of life (QOL) of ICU survivors increased. In 1996, we published a study to investigate 1-year survival after hospital discharge and 6-month QOL after intensive care. Now, we compare our previous results with those reported in the recent literature to appraise any changes, and new knowledge in the area. RESULTS: The 1-year survival of ICU patients after hospital discharge is substantial, lower than in the general population, and different among subgroups. Some studies showed a reduction in QOL at 6 months, as in our study, while others showed an improvement. Different results seem to be related mainly to the case mix. Studies on different types of patients found long-term cognitive impairment in ICU survivors, possibly not disease specific. The proportions of patients with neuropsychological morbidities such as posttraumatic stress disorder, anxiety, and depression, described after our study, did not show any change over time. CONCLUSIONS: Differences between studies on long-term survival and QOL do not allow conclusions to be drawn about change over time. No change was found in neuropsychological morbidities. However, a lack of change may not be viewed negatively, because critically ill patients who survive ICU today may be at higher risk for poor long-term outcome than in the past due to the higher severity of their illness and the more aggressive treatments received. Future studies may provide understanding of the relationships between psychiatric symptoms, cognitive impairment, functional disability, and QOL.

Factors predictive of patient satisfaction with anesthesia.

BACKGROUND: In this multicenter prospective study, we identified factors associated with satisfaction with anesthesia in patients staying in hospital at least 24 h after surgery. METHODS: The study was performed in six centers. Inpatients aged more than 18 yr, who underwent a wide range of common surgical procedures, were asked to answer a 10-item instrument to measure patient satisfaction with anesthesia (mean score range, 0-10) and some specific questions, and to rate their perceived health (score, 0-10). Anesthesia staff members were invited to self-compile a Maslach Burnout Inventory. RESULTS: The satisfaction evaluation questionnaire was returned by 1290 patients (mean age, 61 +/- 16 yr; males, 54.4%). The mean global satisfaction score was 8.7 (95% CI: 8.7-8.8), being <9 in 632 (49%) and > or =9 in 658 (51%) patients. The Maslach Burnout Inventory was returned by 55 anesthesiologists and 68 nurses. Multivariate regression identified five variables as significant predictors of a mean global satisfaction of >/=9: 1) having been treated in a service with perioperative nurses specifically dedicated only to anesthesia; 2) having been treated where anesthesia information leaflets were provided preoperatively; 3) having received more than two anesthesiologist visits after surgery; 4) having a perceived health score >8.5; and 5) being older that 70 yr. No relationship was found between staff burnout and patient satisfaction. CONCLUSIONS: Inpatient satisfaction can be improved by an organization in which surgical suite nurses are dedicated only to anesthesia, a written anesthesia information leaflet is given during the preoperative visit and postoperative visits are enhanced.

The pharmacokinetics and efficacy of ropivacaine continuous wound instillation after spine fusion surgery.

UNLABELLED: Because local anesthetic continuous wound instillation has not been evaluated after spine fusion surgery, we designed this study to determine whether this technique could enhance analgesia and improve patient outcome after posterior lumbar arthrodesis. Thirty-eight patients undergoing spine stabilization were randomly divided into two groups. The M group received a postoperative baseline IV infusion of morphine plus ketorolac for 24 h, and the R group received IV saline. In both groups, a multihole 16-gauge catheter was placed subcutaneously; in the R group, the wound was infiltrated with a solution of ropivacaine 0.5% 200 mg/40 mL, and infusion of ropivacaine 0.2% 5 mL/h was maintained for 55 h. In the M group, saline infusion was given at the same rate. Pain scores were taken at rest and on passive mobilization by nurses blinded to patient analgesic treatment. The total plasma ropivacaine concentration was evaluated. Pain scores and rescue medication requirements (diclofenac and tramadol) were significantly less in the R group than in the M group. Postoperative blood loss was less and the length of hospital stay was shorter in the R group. The ropivacaine peak total plasma concentration occurred at 24 h during infusion and was within safe limits; no toxic local anesthetic side effects were observed. These results suggest that wound infiltration and continuous instillation of ropivacaine 0.2% is effective for pain management after spine stabilization surgery. IMPLICATIONS: Postoperative pain after lumbar arthrodesis is related to soft tissue and muscle dissection and to manipulations and removal at the operation site. By blocking noxious stimuli from the surgical area, infiltration and wound perfusion with ropivacaine were more effective in controlling pain than systemic analgesia.
