Association of Modified Sequential Organ Failure Assessment (MSOFA) Score and C-reactive protein (CRP) With the Outcome of Patients under Mechanical Ventilation

Different scoring systems has been discovered in medical practice, more specifically for ICU treatment, are designed to objectively quantify physiologic derangements and comorbid conditions for estimating mortality, length of stay and ICU resource use. This observational and descriptive study was carried out in the ICU, BSMMU, Dhaka, during March 2014 to May 2016, to determine the association of MSOFA score, CRP level with the outcome of patients on mechanical ventilation as well as compare the MSOFA and CRP combined with MSOFA alone. For this purpose, a total of 60 critically ill patients admitted in the above hospital were included in this study. Patients with an ICU stay of less than 48 hours, readmissions not considered, known case of neuromuscular disease, connective tissue disorder, renal disease and pregnancy and Patients refused to give written consent were excluded from the study. Patients who had MSOFA ≥7, their mean duration of ICU stay were 10.9±6.7 days and mean duration of mechanical ventilation 7.63±5.2 days. Patients who had CRP >11mg/L, their mean duration of ICU stay was 10.8±7.2 days and mean duration of mechanical ventilation was 7.35±5.1 days. Patients who had MSOFA score ≥7 and CRP ≥11mg/L with mean duration of ICU stay was 10.82±7.2 days and mean duration of mechanical ventilation was 7.12±5.2 days. 69.2% patients were CRP status positive (≥11) in death group and 33.3% had alive group. 92.3% patients were Positive (CRP ≥7 or MSOFA ≥11) in death group and 14.3% had alive group. MSOFA identified true positive 32 cases for death, false positive 5 cases, false negative 7 cases and true negative 16 cases confirmed by patient's outcome. CRP level identified true positive 27 cases for death, false positive 7 cases, false negative 12 cases and true negative 14 cases confirmed by patients outcome. Combined (CRP ≥11mg/L and MSOFA score ≥7) identified true positive 33 cases for death, false positive 1 case, false negative 6 cases and true negative 20 cases confirmed by patient's outcome. We concluded that there is a positive correlation (r=0.323; p=0.014) between CRP status with MSOFA score, positive correlation (r=0.402; p=0.002) between MSOFA score with MSOFA score and CRP combined and a positive correlation (r=0.999; p=0.001) between CRP level with MSOFA score and CRP combined.

Level of Serum Vitamin D, To Which People Are at Risk of Developing Acute Myocardial Infarction in Bangladesh

Incidence of Myocardial Infarction is increasing day by day in developing countries. Most of the patients who sustain myocardial infarction have coronary atherosclerosis. There are several risk factors for the development of atherosclerosis. Among all the risk factors, vitamin D deficiency has been proposed to play an important role in the development of atherosclerosis. With this aim, a case-control study was carried out to explore the association of serum vitamin D with acute myocardial infarction. The enrolled study subjects were categorized into Group A which comprised of STEMI, Group B, comprised of NSTEMI and Group C comprised of age and sex matched individuals free from acute myocardial infarction. The mean values of serum vitamin D (in ng/ml) were 20.17, 20.8 and 24.77 respectively in STEMI, NSTEMI and control groups. It differed significantly among groups (p<0.001) and it was significantly low in STEMI and NSTEMI groups compared to control group (p<0.001 and p=0.004). From this study it can be concluded that low serum vitamin D is an independent risk factor for developing acute myocardial infarction. Individuals with serum vitamin D <20ng/ml have higher chance of developing acute myocardial infarction compared to those with serum vitamin D >20ng/ml.

A Comparative Study Between 20% Mannitol and 3% Hypertonic Saline for Brain Oedema Reduction during Elective Brain Tumour Surgery

Cerebral oedema is an important manifestation of brain tumour. The significant reduction of cerebral oedema can show rapid improvement of the patients. Hypertonic saline solution and mannitol both are commonly used for this action. It is now time to choose the better one. This was a prospective randomized comparative study designed to evaluate the efficacy of 3% hypertonic saline (NaCl) in reduction of brain oedema during brain tumour surgery and compare it with that of 20% Mannitol. The study was conducted in the department of Anaesthesiology, Combined Military Hospital, Dhaka, Bangladesh from July 2016 to December 2016. A total number of 47 patients for brain tumour surgery were selected. After screening 40 patients were finalized. Then the patients were divided into 2 equal groups 20 patients in each. Patients of Group A received 3% hypertonic saline and Group B 20% mannitol. Uniform anaesthetic technique applied for all patients, fixed surgeon/group of surgeons carried out the surgery. Heart rate and noninvasive blood pressure were monitored and kept with in ±20% baseline values different means. ETCO2 were kept in between 28-32mm of Hg by adjusting ventilator setting. Reduction of brain oedema was monitored by subjective assessment of surgeons using a 3 point scale of brain relaxation. The data were recorded in preformed data sheet. The results were tested by chi-square test to see their level of significance i.e. p value <0.05 was considered as significant. At the opening of dura, the number of brain conditions classified as soft, adequate and tight were statistically non-significant between groups. After 0.5 hour and 1.0 hour 10% patient's brain was tight in Group A whereas it was 35% and 40% in Group B respectively. Reduction of brain oedema or brain relaxation was significantly better in Group A compared to Group B (p<0.05). Urine output was higher with mannitol than hypertonic saline (p<0.05). Duration of ICU and hospital stay in both Group A and Group B were statistically similar (p>0.05). Compared to mannitol, hypertonic saline caused an increase in serum sodium concentration over time (p<0.05). From the available data, use of 20% mannitol and 3% hypertonic saline for brain oedema reduction, it is suggested that hypertonic saline significantly reduces the risk of tight brain and produce the brain more soft than mannitol during brain tumour surgery.
