Ministernotomy (MS) is an alternative for total sternotomy (TS) in aortic valve replacement. We compared these two approaches for results and adverse effects in a prospective study. From January to December 2000, 100 patients who underwent aortic valve replacement were included in two groups of 50 according to the surgical approach that used MS or TS; one senior surgeon performed all cases in each group. Valvular pathologies were either stenosis or insufficiency. Mean age was 63 +/- 14 years in MS, 67 +/- 12 in TS (p = ns). NYHA class was 2.7 +/- 0.5 in MS, 2.8 +/- 0.6 in TS (p = ns). Left ventricular ejection fraction was 58 +/- 12% in MS, 57 +/- 12% in TS (p = ns). There was a significant difference between MS and TS in aortic cross-clamping (66 +/- 14 min vs 48 +/- 9 min) and cardiopulmonary bypass (88 +/- 18 min vs 69 +/- 10 min, p < 0.01), but not in intervention times (2.8 +/- 0.4 hours vs 2.7 +/- 0.4 hours). Mean intensive care stay was reduced in MS (1.7 +/- 1.6 days vs 2.6 +/- 6 days, p < 0.05). Intubation times (12 +/- 7 hours vs 14 +/- 9 hours), 24 hours bleeding (394 +/- 219 mL vs 465 +/- 318), reintervention for hemostasis (4% vs 2%), rhythmic complications (14% vs 14%), and mortality at 1 month (2% vs 2%) were comparable in MS and TS. In aortic valve surgery, ministernotomy is technically more demanding and needs more time. It is as safe and as effective as conventional sternotomy but its eventual benefits, excepting upon cosmesis, are still to be defined.

This study confirmed the feasibility of intracavitary electrocardiogram for peripherally inserted central catheter positioning and the limits of chest X-ray. Insertion on left side may represent risk factor for aberrant position but our study lacked power to establish a statistical link.

Background: Increased preoperative delay in patients with hip fractures may be responsible for increased morbidity and mortality. We hypothesized that a strategy of reversal of vitamin K antagonist (VKA) by prothrombin complexes concentrates (PCCs), as compared to vitamin K, is safe and reduces preoperative delay and hospital length of stay (LOS). Methods: In this pilot study, we reviewed the records of patients admitted to a university-affiliated hospital for hip fracture between Jan. 1, 2012, and Dec. 31, 2016, who were taking VKA. Patients were stratified according to reversal strategy (vitamin K v. PCC). Adverse effects, time to surgery, LOS and mortality were collected from the electronic medical record and were compared between the 2 study groups and a control group not treated with VKA. Results: A total of 141 patients were included in the study: 65 in the vitamin K group, 26 in the PCC group and 50 in the control group. The median preoperative delay in the PCC group (20 h [interquartile range (IQR)] 13–25 h]) and the control group (20 h [IQR 15–33 h]) was lower than that in the vitamin K group (45 h [IQR 31–52 h]) (p < 0.001). Patients in the PCC group had a shorter median hospital LOS than those in the vitamin K group (6 d [IQR 4–9 d] v. 8 d [IQR 6–11 d], p < 0.05). No difference was observed in the proportion of patients who received a red blood cell transfusion, or had thrombotic or hemorrhagic complications. No difference in mortality at 12 months was observed between the groups. Conclusion: In patients with hip fracture, the use of PCCs as compared to vitamin K to reverse the effect of VKA significantly reduced preoperative delay and hospital LOS, and was not associated with an increase in the rates of thrombotic or hemorrhagic complications. Prospective studies involving a greater number of patients are required to confirm these promising results.
