Background Increased intra-abdominal pressure causes hemodynamic changes that may affect renal biomarkers. Methods This randomized, single-blind, single-center clinical trial recruited patients undergoing laparoscopic cholecystectomy at a tertiary care center in Brazil. They were randomly allocated to a standard intra-abdominal pressure group (P10-12, 10–12 mm Hg) and a low intra-abdominal pressure group (P6-8, 6–8 mm Hg). The primary outcome was the change in neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C levels measured at the beginning of the procedure (T0), at the end of the procedure (T1), and 24 hours after the procedure (T2). P-values < 0.05 were considered statistically significant. Results In total, 64 patients completed the study—33 were given standard pressure and 31 were given low pressure. There was no significant difference in the biomarker between the groups (P = 0.580), but there was a significant difference between the time points with elevation at T1 (P < 0.001). Similar to NGAL, cystatin C had an elevation at T1 in both groups (P = 0.021), but no difference was found when comparing the groups. Conclusions In laparoscopic cholecystectomy, pneumoperitoneum increases NGAL and cystatin C levels intraoperatively, and the use of low-pressure pneumoperitoneum does not change the course of these biomarkers.

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. Inspiratory, hemodynamic and metabolic changes occur in laparoscopic surgery depending on pneumoperitoneum and patient position. This study aims to evaluate the effects of intra-abdominal pressure increase based on CO2 pneumoperitoneum in laparoscopic operations on hemodynamic parameters and respiratory dynamics and satisfaction of surgeon and operative view.Materials and Methods. A total of 116 consecutive, prospective, ASA class I–III cases aged 18–70 years undergoing laparoscopic cholecystectomy were enrolled in this study. Data of 104 patients were analysed. Patients were divided into two groups as the group Low Pressure (<12 mmHg) (Group LP) (n=53) and the group Standard Pressure (>13 mmHg) (Group SP) (n=51). In this study administration of general anesthesia used total intravenous anaesthesia in both groups. All groups had standard and TOF monitorization applied. The anaesthesia methods used in both groups were recorded. Before, during and after peritoneal insufflation, the peroperative ventilation parameters and hemodynamic parameters were recorded. The adequacy of pneumoperitoneum, gastric and the operative view were evaluated by the operating surgeon and recorded.Results. The peripheral oxygen saturation showed no significant difference between the low and standard pressure pneumoperitoneum in view of tidal volume, respiratory rate, end tidal CO2, mean and peak inspiratory pressure, and minute ventilation values. In terms of hemodynamics, when values just after intubation and before extubation were compared, it was observed that in the LP group systolic, diastolic and mean blood pressure values were higher. In terms of heart rate, no significant difference was observed in determined periods between groups. There was no significant difference between the groups in terms of surgical satisfaction and vision.Conclusion. Low pressure pneumoperitoneum provides effective respiratory mechanics and stable hemodynamics for laparoscopic cholecystectomy. It also provides the surgeon with sufficient space for hand manipulations. Anaesthetic method, TIVA and neuromuscular blockage provided good surgery vision with low pressure pneumoperitoneum.

Objective Neck dissection (ND) is one of the most commonly performed procedures in head and neck surgery. We sought to compare the morbidity of elective ND (END) versus therapeutic ND (TND). Study Design Retrospective chart review. Setting Academic tertiary care center. Methods Retrospective chart review of 373 NDs performed from January 2015 to December 2018. Patients with radical ND or inadequate chart documentation were excluded. Demographics, clinicopathologic data, complications, and sacrificed structures during ND were retrieved. Statistical analysis was performed with χ2 and analysis of variance for comparison of categorical and continuous variables, respectively, with statistical alpha set a 0.05. Results Patients examined consisted of 224 males (60%) with a mean age of 60 years. TND accounted for 79% (n = 296) as compared with 21% (n = 77) for END. Other than a significantly higher history of radiation (37% vs 7%, P < .001) and endocrine pathology (34% vs 2.6%, P < .001) in the TND group, no significant differences in demographics were found between the therapeutic and elective groups. A significantly higher rate of structure sacrifice and extranodal extension within the TND group was noted to hold in overall and subgroup comparisons. No significant difference in rate of surgical complications was appreciated between groups in overall or subgroup analysis. Conclusion While the significantly higher rate of structure sacrifice among the TND population represents an increased morbidity profile in these patients, no significant difference was found in the rate of surgical complications between groups. The significant difference seen between groups regarding history of radiation and endocrine pathology likely represents selection bias.

Abstract Introduction: Emergency Medical Services (EMS) providers are trained to place endotracheal tubes (ETTs) in the prehospital setting when indicated. Endotracheal tube cuffs are traditionally inflated with 10cc of air to provide adequate seal against the tracheal lumen. There is literature suggesting that many ETTs are inflated well beyond the accepted safe pressures of 20-30cmH2O, leading to potential complications including ischemia, necrosis, scarring, and stenosis of the tracheal wall. Currently, EMS providers do not routinely check ETT cuff pressures. It was hypothesized that the average ETT cuff pressure of patients arriving at the study site who were intubated by EMS exceeds the safe pressure range of 20-30cmH2O. Objectives: While ETT cuff inflation is necessary to close the respiratory system, thus preventing air leaks and aspiration, there is evidence to suggest that over-inflated ETT cuffs can cause long-term complications. The purpose of this study is to characterize the cuff pressures of ETTs placed by EMS providers. Methods: This project was a single center, prospective observational study. Endotracheal tube cuff pressures were measured and recorded for adult patients intubated by EMS providers prior to arrival at a large, urban, tertiary care center over a nine-month period. All data were collected by respiratory therapists utilizing a cuff pressure measurement device which had a detectable range of 0-100cmH2O and was designed as a syringe. Results including basic patient demographics, cuff pressure, tube size, and EMS service were recorded. Results: In total, 45 measurements from six EMS services were included with ETT sizes ranging from 6.5-8.0mm. Mean patient age was 52.2 years (67.7% male). Mean cuff pressure was 81.8cmH2O with a range of 15 to 100 and a median of 100. The mode was 100cmH2O; 40 out of 45 (88.9%) cuff pressures were above 30cmH2O. Linear regression showed no correlation between age and ETT cuff pressure or between ETT size and cuff pressure. Two-tailed T tests did not show a significant difference in the mean cuff pressure between female versus male patients. Conclusion: An overwhelming majority of prehospital intubations are associated with elevated cuff pressures, and cuff pressure monitoring education is indicated to address this phenomenon.

<b><i>Background and Aim:</i></b> Although anyone can be affected by the COVID-19 pandemic, it may cause additional concern for people with chronic conditions. Epilepsy is the most common neurological disease in childhood and adolescence. The aim of this study was to determine anxiety levels among the mothers of children under follow-up for epilepsy in our clinic during the COVID-19 pandemic. <b><i>Methods:</i></b> The study group consisted of the mothers of epilepsy patients who were under follow-up in the pediatric neurology outpatient clinic of the tertiary care center and were scheduled for a routine examination during the COVID-19 pandemic. The mothers’ anxiety levels according to the Beck Anxiety Inventory and their opinions about COVID-19 in relation to their child were assessed and compared based on whether the mother/patient attended their appointments in person and whether the child had frequent or infrequent seizures. <b><i>Results:</i></b> There was no statistically significant difference in anxiety level between the mothers of 64 children with epilepsy who attended their appointment during the pandemic and those of the mothers of 52 who did not attend their appointment. However, the mothers of children with frequent seizures had significantly higher anxiety levels. <b><i>Conclusion:</i></b> Anxiety level of mothers whose children have frequent seizures was significantly higher compared to mothers whose children have infrequent seizures. It is important to be aware about this point and using telemedicine approach in suitable population and postpone routine outpatient follow-up appointments as much as possible.

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.

Objectives: To describe the incidence of and risk factors for acute kidney injury (AKI) in children with acute respiratory distress syndrome (ARDS) and study the effect of AKI on patient outcomes. Design: A single-center retrospective study. Setting: A tertiary care children’s hospital. Patients: All patients less than 18 years of age who received invasive mechanical ventilation (MV) and developed ARDS between July 2010 and July 2013 were included. Acute kidney injury was defined using p-RIFLE (risk, injury, failure, loss, and end-stage renal disease) criteria. Interventions: None. Measurements and Main Results: One hundred fifteen children met the criteria and were included in the study. Seventy-four children (74/115, 64%) developed AKI. The severity of AKI was risk in 34 (46%) of 74, injury in 19 (26%) of 74, and failure in 21 (28%) of 74. The presence of AKI was associated with lower Pao 2 to Fio 2 (P/F) ratio ( P = .007), need for inotropes ( P = .003), need for diuretics ( P = .004), higher oxygenation index ( P = .03), higher positive end-expiratory pressure (PEEP; P = .01), higher mean airway pressure ( P = .008), and higher Fio 2 requirement ( P = .03). Only PEEP and P/F ratios were significantly associated with AKI in the unadjusted logistic regression model. Patients with AKI had a significantly longer duration of hospital stay, although there was no significant difference in the intensive care unit stay, duration of MV, and mortality. Recovery of AKI occurred in 68% of the patients. A multivariable model including PEEP, P/F ratio, weight, need for inotropes, and need for diuretics had a better receiver operating characteristic (ROC) curve with an AUC of 0.75 compared to the ROC curves for PEEP only and P/F ratio only for the prediction of AKI. Conclusions: Patients with ARDS have high rates of AKI, and its presence is associated with increased morbidity and mortality.

Purpose: Goldmann applanation tonometry (GAT) is considered the gold standard for Intraocular Pressure (IOP) measurement. It has the disadvantages of being a contact device, need for a slit-lamp, non-portability and need of a skilled examiner. Many hospitals are using a Non Contact Tonometry (NCT) as a screening device to save clinician time, however the usefulness is not proved in terms of reliability. This study was aimed to determine the usefulness of the Air-puff tonometer (TONOREF NIDEK II, NIDEK CO., LTD., JAPAN) over a GAT in a tertiary care center. Design: Cross-sectional Study Methods: This was a cross-sectional, non interventional observational study conducted on 224 eyes (right eye) from 224 patients. All patients underwent the IOP measurement with both methods and a central corneal thickness (CCT) measured. The data was analyzed using SPSS 20.0 software. Results: The mean age of the patients was 40.3±11.29 years. There was a statistically significant difference (p<0.001) between the mean NCT and GAT readings which persisted even after correction for central corneal thickness. The correlation between NCT and GAT using Pearson’s correlation coefficient was strong irrespective of the corrections for their corneal thickness (r = 0.751 and 0.718 for uncorrected and corrected values respectively). The correlation of the individual clinicians for the readings varied from moderate to strong. The ROC curve showed the best sensitivity and specificity to occur at around 13 to 14 mmHg. Conclusion: NCT seems to overestimate the IOP at low ranges as compared to the GAT and underestimate at higher ranges. The crossover of the values is seen between 12 to 13 mmHg.  The clinician should do an individualized analysis of his/her GAT measurements to the readings of the NCT machine at the clinic to obtain clinician specific nomogram.
