RESUMEN
INTRODUCTION: Dexamethasone is commonly administered in intracranial tumors to reduce the cerebral edema. Its administration may be associated with hyperglycemia. The primary objective of this study was to study the magnitude of rise in blood sugar levels following the administration of a single 10 mg dose of dexamethasone. METHODS: Seventy patients who underwent various neurosurgical procedures were enrolled in the study. Group D (n = 35 undergoing surgery for intracranial tumors) were administered injection dexamethasone 10 mg while as Group P (n = 35 undergoing surgery for subarachnoid hemorrhage) received placebo. Blood samples were obtained through the arterial line at baseline (before dexamethasone administration), 60, 120, 180, and 240 min after the dexamethasone administration and blood glucose concentrations noted. RESULTS: Glucose concentrations were significantly increased in patients who received dexamethasone compared with those who received placebo (P < 0.05). Blood glucose concentrations at different time intervals were greater when compared with the baseline blood sugar levels in both the placebo and dexamethasone group (P < 0.05). The arterial blood glucose concentration in those who received 10 mg dexamethasone (n = 35) increased from 95.29 ± 13.69 mg.dl-1 to 139.97 ± 10.34 mg.dl-1 over 4 h, compared with a change from 94.74 ± 10.05 mg.dl-1 to 122.34 ± 10.68 mg.dl-1 in those who received placebo (n = 35) (P < 0.05). CONCLUSION: The administration of a single intravenous dose of 10-mg dose dexamethasone caused a significant increase in the blood glucose concentrations at different point intervals when compared with the placebo over a 4-h period. We recommend intensive monitoring of the blood sugar levels during the intraoperative period to prevent the development of severe hyperglycemia and its associated complications.
RESUMEN
INTRODUCTION: Traumatic brain injury (TBI) is a major cause of death and disability throughout the world. Commonly used predictors of outcome both individually or in combination include age, Glasgow Coma Scale score, pupillary reactivity, early hypoxia, and hypotension. Most of the studies previously done to examine risk factors for mortality in severe TBI were done in the setting of polytrauma. AIMS AND OBJECTIVES: The aim and objective of this study was to do an in-depth analysis of various factors associated with the management and outcome of patients with isolated TBI admitted in an Intensive Care Unit (ICU). MATERIALS AND METHODS: A total of seventy adult patients who were admitted to Intensive Critical Care Unit (ICU) with isolated TBI were selected during a 12-month period from January 2016 to December 2016. This is a prospective analytical study and parameters studied included age, sex, cause of admission classified by type of trauma, premorbid functional status, acute and chronic comorbidities, brain noncontrast computed tomography scan data, Glasgow Coma Scale (GCS), hemodynamic status, respiratory status, and mechanical ventilation, blood gases, serum electrolytes, serum glucose, hemoglobin, leukocyte and platelet counts, renal function, and urinary output. RESULTS: The study population consisted of 46 (65.7%) males and 24 (34.2%) females. The mean age was 35.5 years (range, 18-65 years). The most common mode of trauma was road traffic accident (43.6%) followed by fall from height (35.7%). Statistically insignificant relationship (P < 0.05) was seen with sex and mode of injury among survivors and nonsurvivors; however, 61.9% of patients with age ≥40 years died (P < 0.005). Among clinical parameters at admission to ICU, low GCS, hypotension (mean arterial pressure ≤80 mmHg), hypoxia (pO2 ≤60 mmHg, spO2 ≤90 mmHg), and nonreacting pupils were significantly associated with increased mortality (P < 0.05). CONCLUSION: Isolated TBI still continues to have a good amount of morbidity and mortality which perhaps can be reduced by strict adherence to guidelines of management.
