Background Postoperative bleeding in cardiovascular surgery is a frequent and complicated situation for the surgical team, and may also be responsible for significant hospital expenditures. Fibrin glue are indicated in surgery to improve hemostasis when conventional techniques such as compression, sutures or electrocoagulation are insufficient. Through this study, we tried to study the contribution of fibrin glue to the improvement of the clinical parameters (volume of postoperative bleeding, length of stay in intensive care, volume of blood transfusion ...) in two populations having undergone cardiac surgery, one in which we used the fibrin glue and one without fibrin glue. Methods This was a retrospective cohort study conducted in the cardiovascular surgery department of our Hospital in Rabat between June 2012 and June 2015. Fibrin glue (Tissucol® of BAXTER) was used in one group with an haemostatic aim. The pre and post-operative clinical data of the patients were analyzed and compared with data from patients who were operated without the use of fibrin glue because it was not yet available in the hospital. The clinical parameters were collected analyzed using the SPSS 13.0 software. Results One hundred ten patients were included in this study. The fibrin glue was used intraoperatively in 55 patients and not used in 55 patients. 43 (39.1%) had cyanogenic diseases and 67 (60.9%) had non-cyanogenic pathologies. The volume of transfused red blood cells was lower in patients in whom we used biological glue ( p = 0.005), as well as the number of days spent in intensive care ( p = 0.02). However, the difference was not significant between the two groups for other parameters such as bleeding volume per kg, the number of units of fresh frozen plasma and the platelet units count transfused. Conclusions The results we found show that fibrin glue reduces the duration of hospitalization in resuscitation and reduces the number of units of transfused red blood cells to patients after surgery. However, it does not reduce significantly the total postoperative bleeding volume per weight, the number of fresh frozen plasma units or platelets units transfused. The fibrin glue could therefore be of moderate benefit in pediatric cardiac surgery.

Introduction A few years after the discovery and development of anti-infectives, this therapeutic feat gave way to bacterial resistance because of the overconsumption of antibiotics, most often with unjustified prescriptions. The objective was to evaluate the compliance of the prescription of antibiotherapy in the pediatric onco-hematology unit of Rabat Children's Hospital and to determine the drug interactions. Material and methods This is a retrospective study of anti-infectives prescriptions in pediatric onco-hematology. All prescriptions containing an antibiotic or antimycotic were isolated at the end of each month for analysis according to the ANSM standard. The variables of compliance analyzed in the prescriptions were: form, indication, posology, duration of the treatment, drug interactions and number of antibiotics which were prescribed. Results The prescriptions containing at least one anti-infective were 195. All the prescriptions were in conformity with their indications; 111 (57%) of the cases were conform with respect to all criteria; 20 (12%) prescriptions were not conform in their form, 12 (6.6%) contained at least one over-dosed drug and 52 (26.7%) contained at least one under-dosed drug. A drug interaction was found in 15 (7.7%) of cases, of which 12 (6.2%) are precautions for use. A drug interaction is present in 1(6,7%) cases when a single antibiotic is prescribed against 3 (20%) cases when 4 antibiotics are prescribed. ( p = 0.007). Conclusion The number of non-compliances in our study was high. It would therefore be advisable to recommend the establishment of an information system to minimize the non-compliances and to ensure a training program for young doctors on international recommendations.
