Blood glucose level on postoperative day 1 is predictive of adverse outcomes after cardiovascular surgery
ABSTRACT Hyperglycaemia is now a recognized predictive factor of morbidity and mortality after coronary artery bypass grafting (CABG). For this reason, we aimed to evaluate the postoperative management of glucose control in patients undergoing cardiovascular surgery, and to assess the impact of glucose levels on in-hospital mortality and morbidity.
This was a retrospective study investigating the association between postoperative blood glucose and outcomes, including death, post-surgical complications, and length of stay in the intensive care unit (ICU) and in hospital.
A total of 642 consecutive patients were enrolled into the study after cardiovascular surgery (CABG, carotid endarterectomy and bypass in the lower limbs). Patients' mean age was 68+/-10 years, and 74% were male. In-hospital mortality was 5% in diabetic patients vs 2% in non-diabetic patients (OR: 1.66, P=0.076). Having blood glucose levels in the upper quartile range (> or =8.8 mmol/L) on postoperative day 1 was independently associated with death (OR: 10.16, P=0.0002), infectious complications (OR: 1.76, P=0.04) and prolonged ICU stay (OR: 3.10, P<0.0001). Patients presenting with three or more hypoglycaemic episodes (<4.1 mmol/L) had increased rates of mortality (OR: 9.08, P<0.0001) and complications (OR: 8.57, P<0.0001).
Glucose levels greater than 8.8 mmol/L on postoperative day 1 and having three or more hypoglycaemic episodes in the postoperative period were predictive of mortality and morbidity among patients undergoing cardiovascular surgery. This suggests that a multidisciplinary approach may be able to achieve better postoperative blood glucose control.

ABSTRACT: Aims and objectives: The cumulative time that critical care nurses spend implementing a tight glycaemic control (TGC) protocol was estimated in a time-in-motion (TiM) study conducted in a hospital in the UK. Background: TGC protocols were introduced to the critical care setting to reduce hyperglycaemic events in high-risk patients. The time burden to critical care nurses of implementing such protocols has not yet been studied in the UK. Design: A prospective TiM pilot study was conducted in an eligible UK intensive care unit by four protocol-trained observers over five consecutive weekdays from 3 to 7 November 2008. Three nurses were also interviewed on site to gather their attitudes and perceptions about the benefits of and time associated with administering a TGC protocol. Methods: Independent observers shadowed nurses, observing when a blood glucose measurement was taken, when each predefined subtask was completed and the duration of each task. Semistructured interviews with nurses were conducted in-person and one-on-one by a trained study member. Results: Considered together, the episodic median duration of all TGC activities was 6·65 min. Across a total shift, nurses devoted approximately 7% of their time to administering a TGC protocol. Nurses perceived that a TGC protocol is beneficial to patient safety and outcomes in a critical care setting but acknowledged that the tasks can be mildly to moderately tedious. Conclusions: This TiM analysis indicated that the additional responsibility of implementing a TGC protocol represents a substantive commitment of nursing time in a critical care setting. Relevance to clinical practice: The episodic data of our pilot study in the UK contributes further evidence that TGC protocols may be arduous to maintain and constitute a substantial investment of nursing time.Nursing in Critical Care 11/2012; 17(6):279-84.

ABSTRACT: Despite acute myocardial infarction and cardiac surgery accounting for 2 of the most common reasons patients are admitted to the intensive care unit, little attention and investigation have been directed specifically for these patients. This patient population therefore deserves special attention as they are often malnourished but require emergent interventions, making nutrition intervention challenging. This article reviews current medical interventions implemented in critically ill cardiothoracic patients and discusses evidence-based nutrition therapy, including enteral and parenteral feeding, glycemic control, and antioxidant provision.Nutrition in Clinical Practice 04/2012; 27(3):323-34.
