RESUMO

Background Zinc is a trace element essential for the normal functioning of many vital enzymes and organ systems. Studies examining the rates and degrees of zinc deficiency and its consequences in patients with critical illnesses remain scarce. Materials and methods This is a prospective observational study assessing zinc deficiency in critically ill adult patients admitted to a tertiary care intensive care unit (ICU) and its impact on clinical outcomes. Patients were divided into those with normal (≥ 71 µg/dl) and low (≤ 70 µg/dl) zinc levels. Zinc-deficient patients were further divided into mild, moderate, and severe zinc deficiency groups based on zinc levels of 61-70 µg/dl, 51-60 µg/dl, and below 51 µg/dl, respectively. The primary outcome assessed was ICU mortality, and the secondary outcomes were ICU length of stay (LOS), duration of invasive mechanical ventilation (IMV), acute kidney injury (AKI) at admission, need for non-invasive ventilation (NIV), renal replacement therapy (RRT), or vasopressors during the course of the ICU. Other parameters compared included APACHE (Acute Physiology and Chronic Health Evaluation) II, SOFA (Sequential Organ Failure Assessment) score on day 1, and levels of lactate, procalcitonin, calcium, magnesium, phosphate, and serum albumin. The study also compared the mean zinc levels in patients with low and high SOFA scores (scores up to 7 vs. 8 and above) and low and high APACHE II values (scores up to 15 vs. 16 and above). Results A total of 50 patients were included, of whom 43 (86%) were zinc deficient. Mortality in zinc-deficient and normal zinc-level patients was 33% and 43%, respectively (p = 0.602). Patients with zinc deficiency were also older (mean age 69 vs. 49 years, p = 0.02). There was no difference in secondary outcome parameters, except for more zinc-deficient patients needing RRT. Twenty-six of the zinc-deficient patients had severe zinc deficiency, ten moderate, and seven mild (p = 0.663). ICU mortality was approximately 42%, 10%, and 29% in the severe, moderate, and mild deficiency groups, respectively (p = 0.092). Zinc levels were similar between those with low and high APACHE II scores (mean 47.9 vs. 45.5 µg/dl, p = 0.606) as well as between low and high SOFA scores (mean 47.8 vs. 45.7 µg/dl, p = 0.054). Conclusion The present study suggests that zinc deficiency is very common in critically ill patients but does not correlate with their severity of illness, nor does it lead to a poorer outcome in these patients. However, further studies with a larger cohort of patients would be required to make definitive conclusions.

RESUMO

Background: Coronavirus disease 2019 (COVID-19) pneumonia with severe acute respiratory distress syndrome (ARDS) is often associated with a progressive respiratory failure that is refractory to maximal ventilatory support and other ARDS strategies. Studies show evidence of a hypercoagulable state in COVID-19 patients, including capillary thrombosis and alveolar fibrin deposits which impede normal gas exchange. In this context, thrombolysis is considered as a salvage therapy to rescue critically hypoxemic patients. Methods: In this retrospective observational study, the efficacy of thrombolysis on outcome of COVID-19 ARDS with respiratory failure was analyzed. Patients with severe ARDS and d-dimer levels of 5 µg/ml or above were initiated on alteplase, as a 25 mg bolus followed by a 25 mg infusion over 22 h. Primary outcome was intensive care unit (ICU) mortality and secondary outcomes were change in PaO2/FiO2 24 h after thrombolysis, avoidance of intubation, ventilator free days (VFD), and ICU and hospital length-of-stay (LOS). Results: Thirteen out of 34 patients with severe COVID ARDS underwent thrombolysis. They had lower ICU mortality than non-thrombolysed patients (23.1% vs. 71.4%, P = 0.006), greater percentage improvement in PaO2/FiO2 (116% vs. 31.5%, P = 0.002), more VFDs (13 days vs. 0 day, P = 0.004), and lesser requirement for intubation (23.1% vs. 76.2%, P = 0.004). ICU and hospital LOS were similar. Conclusion: Thrombolysis can be considered as a rescue therapy for nonintubated COVID-19 ARDS patients with severe hypoxemic respiratory failure, who show evidence of a procoagulant state. Larger studies are needed before inclusion into the regular treatment protocol for COVID-19 patients.

RESUMO

BACKGROUND: The use of the COVID-19 vaccines Vaxzevria from AstraZeneca and Covishield from Janssen has been associated with sporadic reports of thrombosis with thrombocytopenia, a complication referred to as vaccine-induced immune thrombotic thrombocytopenia (VITT) or vaccine-induced prothrombotic immune thrombocytopenia. It presents commonly as cerebral sinus venous thrombosis (CSVT), within 4-30 days of vaccination. Females under 55 years of age are considered to be especially at high risk. Mortality up to 50% has been reported in some countries. Identification of early warning signs and symptoms with prompt medical intervention is crucial. CASE DESCRIPTION: We report here a case of VITT in a young female who presented 11 days after receiving the first dose of the Covishield vaccine, with severe headache and hemiparesis. She was diagnosed with CSVT with a large intraparenchymal bleed, requiring decompressive craniectomy and extended period on mechanical ventilation. CONCLUSION: The patient was successfully treated with intravenous immunoglobulin and discharged after 19 days in ICU. Although she was left with long-term neurological deficits, an early presentation and a multidisciplinary approach to management contributed toward a relatively short stay in hospital and avoided mortality.

RESUMO

BACKGROUND AND AIMS: Multidrug-resistant, Gram-negative infections are increasingly common in the intensive care unit (ICU). This study compares the occurrence and outcome of colistin-only-sensitive (COS) infections among mechanically ventilated patients at a tertiary hospital ICU. METHODS: The study included adult patients admitted over a period of 2 years, who were intubated and mechanically ventilated for more than 48 h. They were divided into two groups, those with COS infections and those without, and their GCS and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, ICU length of stay, leukocyte count, and mortality were compared. COS patients were divided into neurosurgery, neurology, respiratory, and sepsis with bacteremia groups. The COS organisms in each group, their sources, ICU length of stay, ventilator-free days, and mortality were analyzed. RESULTS: Three hundred and one patients were selected, of whom 41 (13.6%) had COS infections. COS patients had a longer ICU length of stay than non-COS patients (P = 0.001) but comparable APACHE II and GCS scores, leukocyte count, and mortality. The sepsis group accounted for 8 out of 15 (53%) deaths among COS patients (P = 0.03). Acinetobacter baumannii accounted for 61% of the COS infections, Klebsiella pneumonia: 24.4%, Pseudomonas aeruginosa: 12.2%, and Escherichia coli: 2.4%. Endotracheal secretion cultures accounted for 65.8% of COS isolates, urine cultures 17%, pus cultures 7.3%, and blood cultures 4.9%. ICU length of stay, ventilator-free days, and mortality were similar between each COS organism. CONCLUSION: Intubated patients with multidrug-resistant, COS infections have a longer stay in ICU than non-COS patients. COS infections associated with bacteremia have high mortality.

RESUMO

Postneurosurgical bacterial meningitis (PNBM) is an emergency and requires early diagnosis and treatment with appropriate antibiotics. The cornerstone of diagnosis is microbiological analysis of the cerebrospinal fluid (CSF) cytochemical characteristics such as leucocyte count, CSF glucose, and protein concentration and CSF: Serum glucose ratio. However, this is often misleading in PNBM. The role of CSF lactate assay for diagnosis and prognosis has been debated. This case report looks into the serial measurement of CSF lactates in PNBM. It also looks into the role of intrathecal colistin. CSF lactate showed a steady decrease corresponding to improvement in clinical condition. Hence, CSF lactate could have a better prognostic value than other conventional markers in PNBM. Intrathecal colistin, in conjunction with the standard antibiotics, can contribute to a quick resolution of the condition.

RESUMO

INTRODUCTION: Urosepsis is one of the common causes of admission to the Intensive Care Unit (ICU). It has traditionally been treated with antibiotics, but surgical management with Double J [DJ] ureteral stents is gaining popularity. This study compares patients with complicated urosepsis who underwent surgical source control by ureteral stenting with those managed medically. MATERIALS AND METHODS: The study enrolled patients admitted to a tertiary adult ICU with a diagnosis of urosepsis over a period of 2 years. The primary outcomes were renal replacement therapy (RRT) requirement and ICU mortality. The secondary outcomes were ICU and hospital length of stay, ventilator-free days, and inotrope free days. Patients were divided those with obstructive and nonobstructive urinary tract infection (UTI). RESULTS: A total of 58 patients met the criteria, of who 32 had obstructive UTI and were included in Group A, with the remaining 26 with nonobstructive UTI comprised Group B. In Group A, 27 patients underwent source control with ureteral DJ stenting, three patients recovered with medical management, and two who were advised source control did not consent to the procedure. Seventeen patients in Group A and seven patients in Group B required RRT (P = 0.044). There was no significant difference in ICU mortality, hospital mortality, and 28 days survival between the two groups. CONCLUSION: With early source control, obstructive UTI outcomes were comparable to nonobstructive UTI. However, despite undergoing ureteric stenting, more patients with obstructive UTI required RRT than those with nonobstructive UTI.

RESUMO

BACKGROUND: Organophosphorus (OP) pesticide poisoning is a major clinical and public health problem in India. Mortality rate remains high at 15%-30%. AIMS: This prospective, observational study examines the relationship between pseudocholinesterase (PChE) activity and morbidity and mortality in OP poisoning. SETTING AND DESIGN: OP poisoning cases admitted to a tertiary care center Intensive Care Unit (ICU) over 5 years from 2010 to 2014 were studied. METHODS: Patients <16 years of age, those on steroids and those with neuromuscular weakness, were excluded from the study. Serum PChE level at admission was estimated and the severity of poisoning assessed accordingly. Primary outcome measures were ICU length of stay and ventilator-free days. Secondary outcome measures included vasopressor-free days, amount of atropine given, hospital length of stay, and ICU mortality. RESULTS: There were 37 patients included in the study, aged between 24 and 44 years, of which 65% were male. They were divided into two groups according to PChE levels. Group A with PChE levels more than 1000 IU/L had twenty patients and Group B with levels <1000 IU/L had 17 patients. Group B had longer ICU length of stay (P < 0.001) and fewer ventilator-free days (P < 0.001). They also had a fewer vasopressor-free days and a longer stay in hospital. CONCLUSIONS: PChE level at presentation is a reliable indicator of the severity of OP poisoning and a predictor of the need for mechanical ventilation and the duration of stay in the ICU.

RESUMO

BACKGROUND: Benefit of early enteral feeds in surgical patients admitted to Intensive Care Units (ICUs) has been emphasized by several studies. Apprehensions about anastomotic leaks in gastrointestinal surgical patients prevent initiation of early enteral nutrition (EN). The impact of these practices on outcome in Indian scenario is less studied. AIMS: This study compares the impact of early EN (within 48 h after surgery) with late EN (48 h postsurgery) on outcomes in abdominal surgical ICU patients. SETTINGS AND DESIGN: Postabdominal surgery patients admitted to a tertiary referral hospital ICU over a 2-year period were analyzed. METHODS: Only patients directly admitted to ICU after abdominal surgery were included in this study. ICU stay>3 days was considered as prolonged; with average ICU length of stay (LOS) for this ICU being 3 days. The primary outcome was in-patient mortality. ICU LOS, hospital LOS, infection rates, and ventilator days were secondary outcome measures. Acute Physiology and Chronic Health Evaluation II scores were calculated. SPSS and Microsoft Excel were used for analysis. RESULTS: Of 91 ICU patients included, 58 received early EN and 33 late EN. Hospital LOS and infection rates were less in early EN group. Use of parenteral nutrition (odds ratio [OR] 5.25, 95% confidence interval (CI); P = 0.003) and number of nil-per-oral days (OR 8.25, 95% CI; P ≤ 0.001) were other predictors of prolonged LOS. CONCLUSIONS: Early EN in postabdominal surgery ICU patients was associated with reduced hospital LOS and infection rates. ICU LOS, duration of mechanical ventilation and mortality rates did not vary.

RESUMO

BACKGROUND: Hyponatremia is one of the most common electrolyte abnormalities encountered in clinical practice and has a significant impact on morbidity and mortality in hospitalized patients. The optimal management of hyponatremia is still evolving. Over the last decade, vaptans have been increasingly used in clinical practice with promising results. MATERIALS AND METHODS: The study included eighty patients with symptomatic hyponatremia due to syndrome of inappropriate antidiuretic hormone (SIADH) admitted and treated in Intensive Care Unit (ICU) with either conivaptan or hypertonic (3%) saline. They were compared for time taken to achieve normal serum sodium, length of ICU and hospital stay, and adverse effects. RESULTS: The demographic data and serum sodium levels at admission were comparable between the two groups. After initiating correction, sodium levels at 6, 12, and 24 h were similar between the two groups. However, at 48 h, patients in the conivaptan group (Group C) had higher sodium levels (133.0 ± 3.8 mEq/L) as compared to hypertonic saline group (Group HS) (128.9 ± 2.6 mEq/L), which was statistically significant (P < 0.001). The length of ICU stay was less in the Group C (3.35 ± 0.89 days) when compared with the Group HS (4.61 ± 0.91 days) (P < 0.001). There was no significant difference in mortality between the two groups. CONCLUSION: In patients with symptomatic hyponatremia due to SIADH, conivaptan with its aquaresis property can achieve a significantly better sodium correction, resulting in reduced ICU and hospital stay with no significant adverse effects.

RESUMO

Chronic pancreatitis is a rare cause of recurrent pleural effusion. Here is a case of recurrent massive left pleural effusions due to pancreaticopleural fistula (PPF) secondary to asymptomatic chronic pancreatitis. Pleural fluid analysis was inconclusive. Diagnosis was made by CT chest and abdomen and confirmed by MRCP and MRI. He required surgical intervention although medical management with pancreatic ductal stenting is the first line of treatment.
