Background Sleep is essential for full mental and physical renewal. Cardiac surgery improves the life expectancy and quality. But unfortunately, some patients lacked that merit as they suffered sleep disturbance. We used validated questionnaire applied to 153 cardiac surgery patients to assess the sleep disturbances after surgery. Results About 70 (45.8%) had valve procedure, 55 (36%) had revascularization, 19 (12.4%) had both procedures and 9 (5.8%) had other procedures. The majority had no post-operative bleeding nor infection. About 78% had sleeping difficulty for one month. About 50% used different medications to fall asleep, mostly analgesics. About 76% slept after 2–6 h irrespective of sleep quality. Some patients had poor sleep quality in the form of nightmares and night terrors. Conclusion Sleep quality was disturbed immediately following cardiac surgery. There was a reduction of night sleep compensated by increased daytime sleepiness. These changes almost reverted one month after surgery.

Background Occurrence of acute oliguric renal failure in the immediate postoperative period carries important morbidity and mortality after a successful cardiac surgical procedure. Adult cardiac and aortic surgical procedures are especially prone to this complication with the incidence varying between 2% to 15% and the mortality rate as high as 40% to 60%. Aim of the Work to compare between furosemide versus mannitol as a renal protection after adult cardiac surgery. Patients and Methods This prospective comparative trial was conducted at Academy of Cardiothoracic Surgery Ain Shams University on patients undergoing CABG operation consisting of a total of 50 patients with normal renal function, EF of greater than 40%, normal protein and electrolyte levels. Results the study revealed no statistically significant difference between groups according to cystatin-C Conclusion The difference between patients given mannitol and patients given furosemide regarding urinary microalbumin, urinary creatinine and serum cystatin-c was insignificant. Addition of mannitol to the priming solution of the cardiopulmonary bypass acts as a renal protector against AKI postoperative. Finally, giving furosemide infusion to patients undergoing cardiac surgery at the beginning of the CPB improves renal perfusion.

Background: Left ventricular ejection fraction is an independent determinant of the outcome of coronary artery bypass surgery. Low preoperative ejection fraction requires special care in terms of pharmacological and mechanical inotropic support. Adrenaline is the most widely used inotropic drug, while levosimendan is a relatively new inotropic drug in the field of cardiac surgery. In this study, we aimed to evaluate the relative efficacy of levosimendan in low ejection fraction patients undergoing coronary artery bypass grafting (CABG). Methods: A retrospective comparative study was performed with 63 patients who underwent isolated on-pump elective CABG with a preoperative ejection fraction below 40%. Patients were allocated to the adrenaline group (n = 35) and levosimendan group (n = 28). Patients were further stratified according to ejection fraction above 30% and below or equal to 30%. The primary outcome was cardiac-related mortality, while other parameters were considered secondary endpoints. Results: EuroSCORE of the adrenaline group was 3.34 ± 1.26 and for the levosimendan group 3.15 ± 1.42 (p value 0.576). Nine patients of the adrenaline group had new postoperative atrial fibrillation compared to seven patients in the levosimendan group (p value 0.948). Two patients of the adrenaline group had postoperative ventricular arrhythmia compared to only one patient in the other group (p value 0.691). The adrenaline group had higher doses of inotropic support compared to the levosimendan group 210.84 ± 23.74 and 157.4 ± 22.69 ng/kg/min respectively
