Filter by:This is an open label randomized controlled trial with two parallel groups to compare the effects of early initiation of oral diet to reduce the post-operative fasting time in adult patients undergoing cardiac surgery.Primary Objectives: - To assess the impact of early and conventional diet on post-operative nausea and vomiting by calculating the simplified PONV (post-operative nausea and vomiting) impact score of patients after cardiac surgery, with a score >5 indicating clinically significant PONV. - To study the impact of early versus conventional diet on gastrointestinal function by estimating the difference in timing of the first bowel movement in patients following cardiac surgery. Secondary Objectives: - To evaluate the effects of early versus conventional diet resumption on length of ICU stay among the patients following cardiac surgery in days. - To compare the satisfaction levels of patients by visual analogue scale who resumed their oral diets early versus conventionally following cardiac surgery. The estimated sample size of 196 patients with routine post operative recovery after cardiac surgery will be randomized into early (interventional) and late (control) diet groups. Researchers will compare the early diet group with late diet group to see the effects.
Postoperative delirium is an acute syndrome of mental deterioration characterized by acute onset and fluctuating course during the day. Very frequent delirium is a presage of other serious comorbidities i.e.: sepsis, acute kidney injury, circulatory and/or respiratory failure. A detailed knowledge of symptoms and early diagnose of delirium increase the chances of early therapy. To what extent the occurrence of postoperative delirium influences hospital therapy in the Cardiac Surgical Postoperative ICU in University Clinical Centre in GdaĆsk is unknown so far.
Non-encapsulated (free) heme, a breakdown component of hemoglobin, is associated with oxidative stress and inflammation with consequent cellular and tissue injury (Ryter & Tyrrell, 2000) (D T G Wagener, et al., 2001). Cardiopulmonary bypass is known to cause trauma to cellular components of the blood, to trigger an inflammatory response, and alter the rheology of the circulation. Prior research has demonstrated an increase in levels of free heme with cardiopulmonary bypass (Wetz, Richardt, Schotola, Bauer, & Bräuer, 2017) (Kubota, Egi, & Mizobuchi, 2017). The stress response to cardiac surgery and utilization of blood salvage techniques independent of cardiopulmonary bypass may affect plasma free heme levels as well as regulation of heme metabolism pathways. It is unclear whether and to what degree plasma levels of free heme may vary at discreet time points in the perioperative period during cardiac surgery involving both cardiopulmonary bypass and "off-pump" techniques. This is an observational, prospective cohort study in which we will assess for red blood cell trauma, free heme levels, and biomarkers for acute kidney injury at various time points throughout cardiac surgery. Urine and arterial blood samples will be collected at our routine, standard of care time points pre-, intra-, and post-operatively and in addition to the standard clinical tests that will be performed (arterial blood gas analysis and activated clotting time) several additional serum biomarkers will be analyzed. Clinical correlation will be performed with levels. Sub-analysis will be performed on the basis of off vs. on pump CABG cases and also in patient that do/not develop AKI post-operatively.
The aim of this study is to compare retrograde autologous priming (RAP) of the bypass circuit to cell salvage (CS) as part of blood conservation strategies in adult cardiac surgery. It hypothesizes that RAP is at least as effective as cell salvage in terms of blood conservation but at the same time more cost effective.
The aim of the study is to determine whether increasing the heart rate by epicardial atrial pacing after surgery improves the contractile force of the myocardium. After complete weaning from CPB, several pressure-loops of the LV will be recorded at different levels of preload using transoesophageal echo, invasive blood pressure monitoring. The preload will be manipulated by adding fluid from the CPB reservoir or draining fluid into the CPB reservoir.
