Ventricular dysfunction requiring inotropic support frequently occurs after cardiac surgery, and the associated low cardiac output syndrome largely contributes to postoperative death. We aimed to study the incidence and potential risk factors of postcardiotomy ventricular dysfunction (PCVD) in moderate-to-high risk patients scheduled for open-heart surgery. ⋯ This cohort study indicates that age, preoperative ventricular function, myocardial ischemic time, and perioperative bleeding are predictors of PCVD which is associated with poor clinical outcome.

Randomized Controlled Trial
Propofol versus Ketofol for Sedation of Pediatric Patients Undergoing Transcatheter Pulmonary Valve Implantation: A Double-blind Randomized Study.
The study was done to compare propofol and ketofol for sedation of pediatric patients scheduled for elective pulmonary valve implantation in a catheterization laboratory. ⋯ The use of propofol and ketofol is safe and effective for sedation of pediatric patients undergoing pulmonary valve implantation in a catheterization laboratory. However, ketofol has many advantages more than the propofol. Ketofol has a rapid onset of sedation, a rapid recovery time, decreased incidence of nausea and vomiting and leads to rapid discharge of patients from the postanesthesia care unit.

Observational Study
Coagulopathies in cyanotic cardiac patients: An analysis with three point - of - care testing devices (Thromboelastography, rotational thromboelastometry, and sonoclot analyzer).
In the last few years, viscoelastic point-of-care (POC) coagulation devices such as thromboelastography (TEG), rotational thromboelastometry (ROTEM), and Sonoclot (SON) analyzer have been increasingly used in major surgeries for timely assessment and management of coagulopathies. The aim of the present study was to evaluate coagulation profile of cyanotic cardiac patients with TEG, ROTEM, and SON analyzer. In addition, we assessed the correlation of standard laboratory coagulation tests and postoperative chest drain output (CDO) with the parameters of POC testing devices. ⋯ Cyanotic cardiac patients have preoperative coagulation abnormalities in ROTEM, TEG, and SON parameters. ROTEM FIBTEM is highly predictive of hypofibrinogenemia while SON PF is highly predictive of thrombocytopenia. ROTEM FIBTEM can be studied as a marker of increased postoperative CDO.

Observational Study
Thyromental height test for prediction of difficult laryngoscopy in patients undergoing coronary artery bypass graft surgical procedure.
Patients undergoing coronary artery bypass graft (CABG) procedures have higher incidence of difficult laryngoscopy and intubation than general surgery population. Accurate prediction of difficult laryngoscopy in CABG patients is desirable to reduce the hemodynamic response and myocardial oxygen requirements. Recently, thyromental height test (TMHT) has been proposed as one of the highly sensitive and specific bedside tests to predict difficult airway. We, in our prospective observational study, evaluated the accuracy of the TMHT in predicting difficult laryngoscopy. ⋯ TMHT had a higher sensitivity compared to other tests along with good positive and negative predictive value and a very high specificity.

Methylene blue (MB) has been used to treat refractory hypotension in a variety of settings. ⋯ MB modestly increases MAP in cardiac surgery patients with VS. Higher MAP at the time of drug administration and surgery with deep hypothermic circulatory arrest predict a greater drug response.
