Abstract

Background and Aim: Excessive Bleeding continues to play a key role and an important cause of morbidity and mortality after cardiopulmonary bypass (CPB). The goal of this study was to determine the differences in bleeding and transfusion between OPCAB and on -pump CABG patients.

Materials and Methods: In a randomized, double blinded prospective study 300 patient's undergoing coronary revascularization surgery were enrolled, 150 CABG patients were compared with 150 OPCAB patients. The patients were assessed during the first 72 hours to determine the postoperative side effects. The 2 groups were compared using the chi-square test or fisher's exact test and the rank sum test.

Results: CABG patients received more intraoperative red blood cells (P<0.0001), more albumin and more fresh- frozen plasma (P<0.0001). Postoperatively, CABG patients were more likely to receive more platelets (29.3% ν 70.7 %, P<0.007). During the operative and the initial 4-hour postoperative period OPCAB patients exhibited greater blood loss (P<0.0001) however, at 12,24and 72 hours postoperatively, CABG patients exhibited greater blood loss. There were4 death in CABG patients (P<0.05)

Conclusion: Despite not reversing the heparin at the end of the OPCAB surgery, OPCAB surgery was associated with an overall reduction in platelets, fresh- frozen plasma, Albumin and transfusion requirements.

Abstract

Background and Aim: In angiography, the lens of the eye may be exposed to radiation and cause cataracts. In Iran, at present, only a single film dosimeter is used under the lead-apron to evaluate individual doses. The aim of this study was to investigate the status of occupational radiation as well as the validity of measuring the dose of the whole body of individuals and eye lenses using a single film dosimeter.
Materials and Methods: In this study, the dose of the whole body and eye lenses were measured using a combination of film and thermoluminescence dosimeters for 35 employees of the angiography departments in three selected hospitals under the auspices of Tehran University of Medical Sciences(TUMS). To measure the eye lens dose, three thermoluminescence dosimeter pellets were used on the forehead, and left and right eyes; and to measure the whole body dose using the two-dosimetry method, a TLD card mounted on the chest and on the lead apron and a film dosimeter on the chest and under the lead apron were used.
Results: The angiography personnel's monthly dose mean of the eye lenses and the whole body were approximately 240.6±6.4 μSv and 120.3±3.3 μSv, 
respectively(the corresponding amount for the annual dose is less than the levels recommended by international authorities). In addition, the dose ratio of film badge to whole body and eye  lens was 0.35 and 0.51, with correlation coefficients of 0.97 and 0.5, respectively. Also, the ratio of eye lens dose to depth dose(TLD) on the lead apron was 1.18 with a correlation coefficient of 0.79.
Conclusion: Using a single film dosimter under the lead apron to estimate the dose of the whole body is almost accurate but this dosimeter alone is not suitable for the assessment of the lens dose of the eye; it is necessary to use an individual dosimeter on the lead apron.
