Randomized Controlled Trial Multicenter Study
Goal-directed therapy improves the outcome of high-risk cardiac patients undergoing off-pump coronary artery bypass.
There has been a constant emphasis on developing management strategies to improve the outcome of high-risk cardiac patients undergoing surgical revascularization. The performance of coronary artery bypass surgery on an off-pump coronary artery bypass (OPCAB) avoids the risks associated with extra-corporeal circulation. The preliminary results of goal-directed therapy (GDT) for hemodynamic management of high-risk cardiac surgical patients are encouraging. The present study was conducted to study the outcome benefits with the combined use of GDT with OPCAB as compared to the conventional hemodynamic management. ⋯ The length of stay in hospital (LOS-H) (7.42 ± 1.48 vs. 5.61 ± 1.11 days, P < 0.001) and ICU stay (4.2 ± 0.82 vs. 2.53 ± 0.56 days, P < 0.001) were significantly lower in the GDT group as compared to control group. The duration of inotropes (3.24 ± 0.73 vs. 2.89 ± 0.68 h, P = 0.005) was also significantly lower in the GDT group. The two groups did not differ in duration of ventilated hours, mortality, and other complications. The parameters such as ScVO 2 , CI, and EVLW had a strong negative and positive correlation with the LOS-H with r values of - 0.331, -0.319, and 0.798, respectively. The study elucidates the role of a goal-directed hemodynamic optimization for improved outcome in high-risk cardiac patients undergoing OPCAB.

Randomized Controlled Trial Observational Study
ProSeal laryngeal mask airway as an alternative to standard endotracheal tube in securing upper airway in the patients undergoing beating-heart coronary artery bypass grafting.
ProSeal laryngeal mask airways (PLMAs) are routinely used after failed tracheal intubation as airway rescue, facilitating tracheal intubation by acting as a conduit and to secure airway during emergencies. In long duration surgeries, use of endotracheal tube (ETT) is associated with various hemodynamic complications, which are minimally affected during PLMA use. However, except for few studies, there are no significant data available that promote the use of laryngeal mask during cardiac surgery. This prospective study was conducted with the objective of demonstrating the advantages of PLMA over ETT in the patients undergoing beating-heart coronary artery bypass graft (CABG). ⋯ In experience hand, PLMA offers advantages over the ETT in airway management in the patients undergoing beating-heart CABG.

Randomized Controlled Trial
Outcome of four pretreatment regimes on hemodynamics during electroconvulsive therapy: A double-blind randomized controlled crossover trial.
Electroconvulsive therapy (ECT) is associated with tachycardia and hypertension. ⋯ Dexmedetomidine 1 μg/kg, 0.5 μg/kg, and esmolol produced significant amelioration of cardiovascular response to ECT without affecting seizure duration, results being best with dexmedetomidine 1 μg/kg. However, the latter has the shortcoming of delayed recovery.
