(1) Age and hemopneumothorax did not affect mortality. (2) ISS was found to a strong predictor on outcome concerning morbidity and prolonged hospitalization but did not influence mortality rate. (3) Mechanical support was not considered a necessity for the treatment of flail chest.
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether bilateral internal thoracic artery (BITA) coronary bypass increases the risk for mediastinitis. Using the reported search 140 papers were identified. Twenty-four papers represented the best evidence on the subject and the author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study comments and weaknesses were tabulated. In general, BITA grafting carries a 2.5- to 5-fold higher risk for mediastinitis after CABG. This risk is about 1.3-4.7% in non-diabetic patients compared to 0.2-1.2% for single internal thoracic artery (SITA) grafting. For diabetic patients with BITA grafting the risk of mediastinitis is significantly increased and can be as high as >10% in some series. However, for patients who undergo BITA harvest using skeletonization the risk is significantly lower and may be similar to patients receiving SITA graft only at around 0.4-2.6%. BITA grafting can be performed with acceptable risk in all patients including higher risk patients such as diabetics, in whom skeletonization of the internal thoracic arteries should be strongly considered rather than pedicled harvest.
In subgroups of patients differing in CHF severity according to the DASI, mean EQ-5D and SF-6D indices differed significantly. Contrarily, in socio-demographic and clinical groups, these utility differences were not directly evident. According to the evidence, comparisons based on severity classification via a valid disease-specific external instrument may provide insight on instrument choice in cost-utility analyses.
The use of opioid analgesics to control pain after median sternotomy in cardiac surgical patients is worldwide accepted and established. However, opioids have a wide range of possible side effects, concerning prolonged extubation time, gastrointestinal tract dyskinesia and urinary tract disorders mostly retention. All these may lead to a prolonged ICU stay or overall hospitalization time increase.Objective: To determine whether a continuous subcutaneous regional anesthetic infusion delivered directly to the sternotomy site would result in decreased levels of postoperative pain and opioid requirements in cardiac surgical patients undergoing median sternotomy.
Method:The continuous subcutaneous infusion (OnQ Painbuster system) was applied in 37 patients. 3 patients were exempted due to prolonged ICU stay. 29 patients underwent CABG, 5 had AVR, 1 MVR and modified Maze, 1 patient had a 3-valve repair due to endocarditis and another one had reconstruction of the left ventricle. Requirements of opioid analgesics were recorded for 96 hours after operation. Pain was assessed using the visual analog scale and the total postoperative hospital length of stay was also measured.
Results:The postoperative pain was significantly diminished (0 -3 at VAS). The mean postoperative length of stay was 5,8 days, rather improved compared to the average stay of 6,7 days.
Conclusion:Continuous subcutaneous infusion of ropivacaine directly at the median sternotomy significantly diminishes postoperative pain and the need for opioid analgesic use. Moreover, it seems to reduce overall postoperative length of stay for all cardiac surgical patients.
The aim of the present protocol is to investigate the potency of thromboelastography (TEG) to screen postcardiac heparin induced thrombocytopenia (HIT) patients suspicious for HIT type II, and to differentiate which of them are subject to suffer thrombotic complications from those who will suffer hemorrhagic complications.
Despite the existence of several sensitive functional and antigen assays used for the diagnosis of heparin-induced thrombocytopenia (HIT), an additional assessment of the patient's hemostatic status, in order to predict the thrombotic complications of the malevolent HIT type II, has become necessary. Herein below, we present the findings of thromboelastography (TEG) in a post-cardiac-surgery patient with the clinical diagnosis of HIT type II and false negative tests for heparin antibodies. We have reached the conclusion that TEG may prove to be a useful supplementary method to predict those HIT patients who may suffer complications of HIT type II.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
