Open Journal of Anesthesiology 2017年第4期7卷 69-82页

Background: Omission of patient information in perioperative communication is closely linked to adverse events. Use of checklists to standardize the handoff in the post anesthesia care unit (PACU) has been shown to effectively reduce medical errors. Objective: Our study investigates the use of a checklist to improve quantity of data transfer during handoffs in the PACU. Design: A cross-sectional observational study. setting: PACU at Memorial sloan Kettering Cancer Center (MsKCC);June 13, 2016 through July 15, 2016. Patients, other participants: We observed the handoff reports between the nurses, PACU midlevel providers, anesthesia staff, and surgical staff. Intervention: A physical checklist was provided to all anesthesia staff and recommended to adhere to the list at all observed PACU handoffs. Main outcome measure: Quantity of reported handoff items during 60 pre- and 60 post-implementation of a checklist. Results: Composite value from both surgical and anesthesia reports showed an increase in the mean report of 8.7 items from pre-implementation period to 10.9 post-implementation. Given that surgical staff reported the mean of 5.9 items pre-implementation and 5.5 items post-implementation without intervention, improvements in anesthesia staff report with intervention improved the overall handoff data transfer. Conclusions: Using a physical 12-item checklist for PACU handoff increased overall data transfer.

药物洗脱支架置入术后长期随访中支架血栓形成的发生率和危险因素

世界核心医学期刊文摘（心脏病学分册） 2006年第12期2卷 19-20页

Despite concerns regarding the long-term safety of drug-eluting stent(DEs) implantation because of late-onset stent thrombosis, the actual incidence of stent thrombosis after 1 year is unknown. We investigated the incidence, risk factors, and association of antiplatelet therapy interruption for the development of stent thrombosis after DEs implantation during long-term follow-up. A total of 1,911 consecutive patients with DEs implantation were enrolled(sirolimus-eluting stents in 1,545 patients, 2,045 lesions; paclitaxel-eluting stents in 366 patients, 563 lesions). During long-term follow-up(median 19.4 months, interquartile range 15.3 to 24.3), 15 patients(0.8%, 95%confidence interval 0.5%to 1.3%) developed stent thrombosis within 6 hours to 20.4 months. Eleven patients(0.6%, 95%confidence interval 0.3%to 1.0%) had late thrombosis(median 6.1 months). The incidence of stent thrombosis was 3.3%(4 of 121 patients) in patients with complete interruption of antiplatelet therapy(vs 0.6%in those without, p=0.004) and 7.8%(5 of 64 patients) with premature interruption of aspirin or clopidogrel, or both(vs 0.5%in those without, ps of stent thrombosis were premature antiplatelet therapy interruption, primary stenting in acute myocardial infarction, and total stent length. stent thrombosis also developed while patients were on dual antiplatelet therapy(all patients with acute/subacute stent thrombosis and 36%of those with late stent thrombosis; 47%of total with stent thrombosis). In conclusion, stent thrombosis occurred in 0.8%after DEs implantation during long-term follow-up. The incidence of late stent thrombosis was 0.6%, similar to that for bare metal stents. The predictors of stent thrombosis were premature antiplatelet therapy interruption, primary stenting in acute myocardial infarction, and total stent length.
