Background. Acute kidney injury (AKI) and metabolic acidosis are common in the intensive care unit. The effect of bicarbonate administration on acid-base parameters is unclear in those receiving continuous venovenous hemofiltration (CVVH) and mechanical ventilatory support.Methods. Metabolic and ventilatory parameters were prospectively examined in 19 ventilated subjects for up to 96 hours following CVVH initiation for AKI at an academic tertiary care center. Mixed linear regression modeling was performed to measure changes in pH, partial pressure of carbon dioxide (pCO2), serum bicarbonate, and base excess over time.Results. During the 96-hour study period,pCO2levels remained stable overall (initialpCO242.0 ± 14.6 versus end-studypCO243.8 ± 16.1 mmHg;P=0.13for interaction with time), for those with initialpCO2≤40 mmHg (31.3 ± 5.7 versus 35.0 ± 4.8;P=0.06) and for those with initialpCO2>40 mmHg (52.7 ± 12.8 versus 53.4 ± 19.2;P=0.57).pCO2decreased during the immediate hours following CVVH initiation (42.0 ± 14.6 versus 37.3 ± 12.6 mmHg), though this change was nonsignificant (P=0.052).Conclusions. We did not detect a significant increase inpCO2in response to the administration of bicarbonate via CVVH in a ventilated population. Additional studies of larger populations are needed to confirm this finding.

NIV is a method of ventilatory support which is delivered to the patient without using an invasive airway. For the last two decades it is increasingly used as an accepted method of mechanical ventilatory support as it is proved to have many positive outcomes as it can prevent invasive ventilation & its complication. In a tertiary care hospital of Bangladesh we are using this method in all patients meeting the NIV criteria & not having absolute contraindication irrespective of diagnosis. Our study aimed to access the out come of the NIV trial using our local resource & to compare it with others. This is an ongoing prospective study and till this report data from 82 patients were analyzed here of which 50% patient ended with positive outcome & 50% ended as negative outcome. As the result of this method varies significantly by diagnosis & severity of disease we are generating specific recommendations according to the likely outcome according to the diagnosis.

Background: Postoperative Acute Kidney Injury (AKI) is a common and serious complication associated with significant morbidity and mortality. While several pre- and intra-operative risk factors for AKI have been recognized in cardiac surgery patients, relatively few data are available regarding the incidence and risk factors for perioperative AKI in other surgical operations. The aim of the present study was to determine the risk factors for perioperative AKI in patients undergoing major abdominal surgery. Methods: This was a prospective, observational study of patients undergoing major abdominal surgery in a tertiary care center. Postoperative AKI was diagnosed according to the Acute Kidney Injury Network criteria within 48 h after surgery. Patients with chronic kidney disease stage IV or V were excluded. Logistic regression analysis was used to evaluate the association between perioperative factors and the risk of developing postoperative AKI. Results: Eleven out of 61 patients developed postoperative AKI. Four intra-operative variables were identified as predictors of AKI: intra-operative blood loss (p = 0.002), transfusion of fresh frozen plasma (p = 0.004) and red blood cells (p = 0.038), as well as high chloride load (p = 0.033, cut-off value > 500 mEq). Multivariate analysis demonstrated an independent association between AKI development and preoperative albuminuria, defined as a urinary Albumin to Creatinine ratio ≥ 30 mg·g−1 (OR = 6.88, 95% CI: 1.43–33.04, p = 0.016) as well as perioperative chloride load > 500 mEq (OR = 6.87, 95% CI: 1.46–32.4, p = 0.015). Conclusion: Preoperative albuminuria, as well as a high intraoperative chloride load, were identified as predictors of postoperative AKI in patients undergoing major abdominal surgery.

Background: Tramadol use has been increasing in the adult and pediatric population. Practitioners must be alert because Tramadol misuse can lead to severe intoxication in which respiratory failure and seizures are frequent. Overdoses can lead to death. We report 47 pediatric cases with history of accidental tramadol exposure in children.Methods: An observational, retrospective, single center case -series of children with a history of accidental tramadol exposure in children admitted in pediatric intensive care unit of tertiary care center, Niloufer Hospital (Osmania Medical College) Hyderabad, Telangana India.Results: Of 47 children, 22 (47%) are male and 25 (53%) were female. At presentation 11 (23%) had loss of consciousness, 14 (29%) seizures, 17 (36%) hypotonia was noted. Pupils were miotic in 22 (47%) mydriatic in 2 (4.2%) normal in rest of children. Hemodynamic instability noted in 13 (27.6%). Serotonin syndrome (tachycardia, hyperthermia, hypertension, hyper reflex, clonus) was noted on 5 (10.6%) children. Respiratory depression was seen in 4 (8%) children who needed ventilatory support. Antidote Naloxone was given in 7 children. No adverse reaction was noted with Naloxone. All 47 children were successfully discharged.Conclusions: Overdoses can lead to death and practitioners must be alert because of the increasing use of tramadol in the adult and pediatric population. The handling of the tramadol should be explained to parents and general population and naloxone could be efficient when opioid toxicity signs are present.

INTRODUCTION: Acute kidney injury is a common occurrence in ICU admissions causing increased morbidity and mortality. Present study aimed to determine the causes and prognostic factors of acute kidney injury in intensive care unit. MATERIAL AND METHODS: This Hospital based Cross sectional Study was conducted at a tertiary care Hospital and Research Center, including 100 patients aged >18 years with Acute Kidney Injury admitted in ICU from the period of October 2018 to June 2020. Patients with chronic renal disease, previous renal transplantation, congenital renal disease were excluded from the study. RESULTS: Most of the patients (63%) were aged above 50 years. Diabetes was found in 55% and hypertension in 26% of AKI cases. Most common cause identied were sepsis, CLD, renal, CNS and CVD. Hypotension occurred in 48% patients, while oliguria occurred in 45% patients. Ventilatory support was required by 43% patients, while 31% patients required haemodialysis. Mortality rate in AKI was 51%. Mortality was signicantly associated with advanced age, presence of Diabetes, and RIFLE criteria. Spot urine <40 meq/L, hyperkalemia, serum creatinine >4 mg/dl, blood urea >100 mg/dl and acidosis were associated with higher mortality. CONCLUSION: Continuous monitoring parameters like Spot Fe Na, Serum Potasium and pH especially in patients at risk, like elderly patients with diabetes, those with sepsis, can help in early identication and appropiate management, thus reduce the incidence or severity of AKI.

The most common acute glomerulonephritis in children is poststreptococcal glomerulonephritis (PSGN) usually occurring between 3 and 12 years old. Hypertension and gross hematuria are common presenting symptoms. Most PSGN patients do not experience complications, but rapidly progressive glomerulonephritis and hypertensive encephalopathy have been reported. This paper reports 17 patients seen in 1 year for PSGN including 4 with atypical PSGN, at a pediatric tertiary care center. Seventeen children (11 males), mean age of 8 years, were analyzed. Ninety-four percent had elevated serum BUN levels and decreased GFR. Four of the hospitalized patients had complex presentations that included AKI along with positive ANA or ANCAs. Three patients required renal replacement therapy and two were thrombocytopenic. PSGN usually does not occur as a severe nephritis. Over the 12-month study period, 17 cases associated with low serum albumin in 53%, acute kidney injury in 94%, and thrombocytopenia in 18% were treated. The presentation of PSGN may be severe and in a small subset have associations similar to SLE nephritis findings including AKI, positive ANA, and hematological anomalies.

Abstract Background Leptospirosis is the most widespread zoonotic disease in the world. In India, it is endemic in coast lined states. Renal failure is a severe complication with mortality approaching 22%, early recognition of which helps clinicians in acting fast. This study aimed to investigate the predictors of Acute Kidney Injury (AKI) in Leptospirosis Methods This is a prospective, case–control study done in a tertiary care center in Southern India carried out between October 2017 and December 2018. Patients with confirmed Leptospirosis as per CDC 2013 and Faine’s criteria (2012) having AKI as per KDIGO criteria were defined as cases. Subjects without AKI were controls. Demographic, clinical and laboratory data were compared between the groups and analyzed. Logistic regression was performed to analyze the possible risk factors associated with AKI in Leptospirosis. Results A total of 329 subjects met the inclusion criteria of the study. 187 patients with AKI (CASES) and 142 patients without AKI (CONTROLS) were studied. Patients with AKI were older, (mean age- 46.99 ± 13.21 vs. 42.99 ± 15.15 years) had longer hospital stay (9.04 ± 5.62 vs. 6.27 ± 3.27 days) had higher SOFA (7.97 ±2.9 vs. 3.37 ± 2.6) and APACHE 2 scores (14.37±5.93 vs. 4.66 ± 4.4), lower mean arterial pressure (84.01 ± 14.45 vs. 89.01 ± 10.63 mmHg; P = 0.001) lower serum bicarbonate level (21.70 ± 2.35 vs. 18.73 ± 3.78 mEq/dL; P < 0.001). Factors like serum lactate, AST, ALT had no significant difference between the groups. Serovar identification was done in 88 patients, of which 57 had AKI. Australis (16.7%), Pyrogenes (16.7%) and Grippotyphosa (11.1%) were the commonest serovars isolated. Serovar most commonly associated with AKI was Pyrogenes (17.5%) Predictors for AKI were jaundice (P = 0.01, OR 2.25; CI 1.21 –3.26), vomiting (P = 0.017, OR 1.9, CI 1.12- 3.26) Hypotension (P = 0.02, OR = 12.3, CI 1.85 – 107.2), tachypnea (P = 0.006, OR = 2.55, CI 1.11- 3.24), leukocytosis (P < 0.001, OR 5.45, CI 1.86- 4.89), thrombocytopenia (P < 0.001, OR 6.49, CI 2.33 – 6.75) Conclusion Identification of features like hypotension, tachypnea, acidosis, leukocytosis, thrombocytopenia, the occurrence of serovar Pyrogenes should alert the clinician on risk of developing AKI Disclosures All authors: No reported disclosures.

Objectives: To study the clinical profile and predictors of acute kidney injury (AKI) in patients with decompensated cirrhosis. Materials and Methods: This observational study was conducted at Himalayan Institute of Medical Sciences, Dehradun, India, on 175 consecutive patients with decompensated cirrhosis. Patients were studied for AKI as per International Club of Ascites-AKI criteria. Results: The prevalence of AKI was 40.6%, with prerenal AKI 67.6%, hepatorenal syndrome (HRS) 23.8%, intrinsic renal AKI 7%, and postrenal AKI 1.4%. Mean arterial pressure (MAP), platelet count, and serum albumin were significantly lower and total leucocyte count (TLC), blood urea nitrogen, serum creatinine (SCr), total bilirubin, aspartate aminotransferase, international normalized ratio, Child-Turcotte-Pugh (CTP) score, and model for end-stage liver disease (MELD) score higher in cirrhosis patients with AKI than without AKI (p < 0.05 each). MAP, hemoglobin, TLC, and SCr were significantly different in various types of AKI (p < 0.05 each). AKI had a significant association with CTP score, alcohol, spontaneous bacterial peritonitis (SBP), sepsis, and shock (p < 0.05 each). Type of AKI had significant association with SBP, sepsis, and shock (p < 0.05 each). Mortality occurred in 33.8% patients with AKI with 64.7% mortality in patients with HRS. Outcome had significant association with AKI, stage and type of AKI (p < 0.05 each). Multivariate analysis showed SBP, sepsis, and shock as independent predictors of AKI (p < 0.05 each). Conclusions: AKI occurred commonly in patients with decompensated cirrhosis. Prerenal AKI and HRS were the most common types of AKI. SBP, sepsis, and shock were important predictors of AKI.
