Comparison of Cefazolin and Ceftriaxone as Antimicrobial Prophylaxis in Pancreatoduodenectomy with Preoperative Drainage: Incidence of Surgical Site Infection and Susceptibility of Bacteria in Bile.

BACKGROUND: The optimal perioperative antimicrobial agent for preventing surgical site infection (SSI) in pancreatoduodenectomy (PD) with preoperative biliary drainage (PBD) remains unclear. METHODS: We retrospectively reviewed 288 patients who underwent PD after PBD between 2010 and 2020 at our institution. Patients were classified into two groups according to the perioperative antimicrobial agent used (cefazoline [CEZ] group [n = 108] and ceftriaxone [CTRX] group [n = 180]). The incidence of SSI, type of bacteria in intraoperative bile culture (IBC), and antimicrobial susceptibility to prophylactic antimicrobial agents were analyzed. RESULTS: The incidence of incisional SSI was significantly lower in the CTRX group than in the CEZ group (18% vs. 31%, P = 0.021), whereas the incidence of organ/space SSI in the two groups did not differ to a statistically significant extent (35% vs. 44%, P = 0.133). Gram-negative rod (GNR) bacteria in the IBC showed better antimicrobial susceptibility in the CTRX group than in the CEZ group. In multivariate analysis, antimicrobial resistance due to GNR was a significant risk factor for incisional SSI (odds ratio, 3.50; P < 0.001). CONCLUSIONS: CTRX had better antimicrobial coverage than CEZ for GNR cultured from intraoperative bile samples. In addition, CTRX provides better antimicrobial prophylaxis than CEZ against superficial SSI in patients with PD after PBD. TRIAL REGISTRATION NUMBER: This study was not a clinical trial and had no registration numbers.

Effect of a do-not-resuscitate order on the quality of care in acute heart failure patients: a single-center cohort study.

BACKGROUND: A do-not-resuscitate (DNR) order is reportedly associated with a decrease in performance measures, but it should not be applied to noncardiopulmonary resuscitation procedures. Good performance measures are associated with improvement in heart failure outcomes. AIM: To analyze the influence of DNR order on performance measures of heart failure at our hospital, where lectures on DNR order are held every 3 months. DESIGN: Retrospective cohort study. METHODS: The medical report of patients with acute heart failure who were admitted between April 2013 and March 2015 were retrospectively analyzed. We collected demographic data, information on the presence or absence of DNR order within 24 hours of admission, and inhospital mortality. Performance measures of heart failure, including assessment of cardiac function and discharge prescription of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker and beta-blocker for left ventricular systolic dysfunction and anticoagulant for atrial fibrillation, were collected and compared between groups with and without DNR orders. RESULTS: In 394 total patients and 183 patients with left ventricular systolic dysfunction, 114 (30%) and 44 (24%) patients, respectively, had a DNR order. Patients with a DNR order had higher inhospital mortality. There were no significant differences between the two groups in terms of the four quality measures (left ventricular function assessment, angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, beta-blocker, and anticoagulant). CONCLUSION: DNR orders did not affect performance measures, but they were associated with higher inhospital mortality among acute heart failure patients.
