ABSTRACT
La incidencia y prevalencia de la diabetes mellitus ha aumentado exponencialmente a nivel mundial en las últimas décadas. Los pacientes diabéticos presentan mayor probabilidad de sufrir graves complicaciones, en los procedimientos quirúrgicos en relación a la población general. El presente artículo tiene como objetivo, describir la repercusión del estado hiperglucémico perioperatorio en la etapa postoperatoria en pacientes diabéticos. Para el logro del objetivo planteado se realizó la consulta de diversas obras, que abarcan los resultados de investigación con diferentes modalidades relacionadas con la temática. Se pudo apreciar que la hiperglucemia perioperatoria se vincula con resultados adversos en pacientes a los que se les realiza cirugía general y que padecen diabetes mellitus, sin embargo, en los pacientes que se ha logrado control glicémico con terapia insulínica antes de la intervención, no presentaron mayor riesgo, que el que aparece en sujetos con buen control metabólico. La regulación de la glucosa en la etapa perioperatoria es un parámetro importante en el paciente diabético, que reduce considerablemente las complicaciones en los procedimientos quirúrgicos, las prolongadas estancias en las Unidades de Cuidados Intensivos, e incluso, la muerte.
The incidence and prevalence of diabetes mellitus has increased exponentially worldwide in recent decades. Diabetic patients are more likely to suffer serious complications in surgical procedures compared to the general population. The objective of this article is to describe the repercussion of the perioperative hyperglycemic state in the post-surgical stage in diabetic patients. In order to achieve the stated objective, various works were consulted, which include the results of research with different modalities related to the subject. It was possible to appreciate that perioperative hyperglycemia is associated with adverse results in general surgery patients with diabetes mellitus, however, in patients who have achieved glycemic control with insulin therapy before the intervention, they did not present a greater risk than that which appears in subjects with good metabolic control. Glucose regulation in the perioperative stage is an important parameter in diabetic patients, which considerably reduces complications in surgical procedures, long stays in Intensive Care Units, and even death.
ABSTRACT
Background: Diabetes is not uncommon in patients requiring cardiac surgery. These patients have a higher incidence of morbidity and mortality. Subsequently, diabetes represents a major medico-economic problem in both developed and developing countries. This study was designed to observe the association between glycemic control and outcome of patients after open heart surgery in adult population. Materials and Methods: Data was collected retrospectively in all patients who underwent open cardiac surgery (coronary artery bypass grafting, valve, or bypass grafting with valve surgery) and survived 72 hours postoperatively and had diabetes. The study was conducted from January 2015 to December 2016. Results: Of the 129 patients included in the study, male dominated 101 (78.3%). Most frequent surgery was coronary artery bypass grafting (CABG) 123 (95.3%), CABG plus aortic valve replacement 4 (3.1%), and CABG plus mitral valve replacement 2 (1.6%). Considering diabetes, only 3 (2.3%) were on diet control, 112 (86.8%) on oral hypoglycemic agents (OHA), whereas 9 (7%) had control on both insulin and OHA. Only 5 (3.9%) had type I diabetes. The mean fasting blood sugar (FBS) was 154.58 g/dl, and the mean duration of diabetic mellitus was observed 12.32 years. Microvascular and macrovascular complications were 26/129 (20.16%) and 17/129 (13.17%), respectively. Total 75 (58.1%) patients did not require insulin and 54 (41.9%) were treated with insulin intraoperatively to keep the blood glucose level less than 200 g/dl. Cardiac arrhythmias were frequent in the insulin group (P < 0.05), which was also associated with increased stay in the cardiac intensive care unit. Conclusion: Inadequate glycemic control during open cardiac surgery can possibly lead to increased perioperative morbidity and mortality and with decreased long-term survival and recurrent ischemic events. Therefore, aiming for blood glucose levels around 140 mg/dl appears reasonable. Further studies are required to define specific glucose ranges for a clearer definition of recommended blood glucose goals in postoperative cardiac patients for the best outcomes in patients with diabetes mellitus.
