Prognostic Value of Admission Blood Glucose Level in Critically Ill Patients Admitted to Cardiac Intensive Care Unit according to the Presence or Absence of Diabetes Mellitus

BACKGROUND: Admission blood glucose (BG) level is a predictor of mortality in critically ill patients with various conditions. However, limited data are available regarding this relationship in critically ill patients with cardiovascular diseases according to diabetic status. METHODS: A total of 1,780 patients (595 with diabetes) who were admitted to cardiac intensive care unit (CICU) were enrolled from a single center registry. Admission BG level was defined as maximal serum glucose level within 24 hours of admission. Patients were divided by admission BG level: group 1 (< 7.8 mmol/L), group 2 (7.8–10.9 mmol/L), group 3 (11.0–16.5 mmol/L), and group 4 (≥ 16.6 mmol/L). RESULTS: A total of 105 patients died in CICU (62 non-diabetic patients [5.2%] and 43 diabetic patients [7.9%]; P = 0.105). The CICU mortality rate increased with admission BG level (1.7%, 4.8%, 10.3%, and 18.8% from group 1 to group 4, respectively; P < 0.001). On multivariable analysis, hypertension, mechanical ventilator, continuous renal replacement therapy, acute physiology and chronic health evaluation II (APACHE II) score, and admission BG level significantly influenced CICU mortality in non-diabetic patients (group 1 vs. group 3: hazard ratio [HR], 3.31; 95% confidence interval [CI], 1.47–7.44; P = 0.004; group 1 vs. group 4: HR, 6.56; 95% CI, 2.76–15.58; P < 0.001). However, in diabetic patients, continuous renal replacement therapy and APACHE II score influenced CICU mortality but not admission BG level. CONCLUSION: Admission BG level was associated with increased CICU mortality in critically ill, non-diabetic patients admitted to CICU but not in diabetic patients.

Predictors and outcome of early extubation in infants postcardiac surgery: A single-center observational study

Objective: The objective of the current study was to evaluate the timing of first extubation and compare the outcome of patient extubated early with others; we also evaluated the predictors of early extubation in our cohort. Materials and Methods: This prospective cohort study included children <1 year of age undergoing surgery for congenital heart disease. Timing of first extubation was noted, and patients were dichotomized in the group taking 6 h after completion of surgery as cutoff for early extubation. The outcome of the patients extubated early was compared with those who required prolonged ventilation. Variables were compared between the groups, and predictors of early extubation were evaluated using multivariate logistic regression analysis. Results: One hundred and ninety-four (33.8%) patients were extubated early including 2 extubation in operating room and 406 (70.7%) were extubated within 24 h. Four (0.7%) patients died without extubation. No significant difference in mortality and reintubation was observed between groups. Patient extubated early had a significant lower incidence of sepsis (P = 0.003) and duration of Intensive Care Unit (ICU) stay (P = 0.000). Age <6 months, risk adjustment for congenital heart surgery category ≥3, cardiopulmonary bypass time ≥80 min, aortic cross-clamp time ≥ 60 min, and vasoactive-inotropic score >10 were independently associated with prolonged ventilation. Conclusion: Early extubation in infants postcardiac surgery lowers pediatric ICU stay and sepsis without increasing the risk of mortality or reintubation. Age more than 6 months, less complex of procedure, shorter surgery time, and lower inotropic requirement are independent predictors of early extubation.

A prospective study of drug utilization pattern in cardiac intensive care unit at a tertiary care teaching hospital.

Background: Cardiovascular diseases remain the most common cause of sudden death. Appropriate drug therapy in cardiac intensive care unit (CICU) is crucial in managing cardiovascular emergencies and to decrease morbidity and mortality. The present study was conducted to observe the emergency cardiac diseases which are most frequently being treated and to study the prescribing prevalence among inpatients in CICU. Methods: A prospective, observational study was carried out among 102 patients admitted in CICU at a tertiary care teaching hospital, Karnataka, for a period of 3 months. Demographic data, clinical history, and complete drug therapy received during their stay in CICU was noted. Results: In our study, males (64.7%) had a higher incidence of cardiovascular emergencies than females (35.3%). Hypertension (32.4%) and Type 2 diabetes mellitus (28.4%) were the frequently associated co-morbid conditions. Antiplatelet drugs 80 (78.4%) was most commonly prescribed, followed by hypolipidemic drugs 75 (73.5%) and anticoagulants 65 (63.7%). The mean duration of stay in the hospital was 4.79±1.9 days. The average number of drugs per prescription was 7.8±2.2. Percentage of drugs prescribed by generic names was 52.9%. The percentage of drugs prescribed from essential drug list was 75.1%. Conclusions: Antiplatelet drugs were the most frequently prescribed drug group. Mean number of drugs per prescription were high. The prescribing pattern could be improved by reducing the number of drugs per prescription and by prescribing generic drugs to reduce the economic burden of the patients.
