RESUMO
Background: The OI was originally evaluated as a prognostic tool for acute hypoxemic respiratory failure in children and was an independent predictor for mortality in adult patients with acute respiratory distress syndrome (ARDS). Methods: Oxygenation index and OSI of 201 adult patients undergoing emergency surgery were evaluated at different time points. The primary objective of this study was to find the correlation between OI and OSI. The secondary objectives were to find the prognostic utility of OI and OSI for postoperative mechanical ventilation and mortality. Results: Significant statistical correlation was found between OI and OSI both at the beginning (r 2 = 0.61; p < 0.001) and immediately after surgery (r 2 = 0.47; p < 0.001). Oxygen saturation index at the beginning [area under the receiver operating characteristics curve (AUROC) (95% CI) 0.76 (0.62-0.89); best cutoff 3.9, sensitivity 64% and specificity 45%] and immediately after surgery [AUROC (95% CI) 0.82 (0.72-0.92); best cutoff 3.57, sensitivity 79%, and specificity 62%] were reasonable predictors of the requirement of invasive ventilatory support. Exploratory analysis reported that older age (p = 0.02), higher total leukocyte count (p = 0.002), higher arterial lactate (p = 0.02), and higher driving pressure (p < 0.001) were independently associated with hospital mortality. Conclusion: In adult patients undergoing emergency laparotomy under general anesthesia, OI and OSI were found to be correlated. Both metrics demonstrated reasonable accuracy in predicting the need for invasive ventilatory support beyond 24 hours and hospital mortality.

RESUMO
Here we have described the anesthetic management of a 10-year-old patient having uremia-induced dilated cardiomyopathy for a living-related adult to pediatric renal transplant. Maintaining optimal hemodynamics, especially during the reperfusion phase, is crucial for maintaining graft perfusion. However, dilated cardiomyopathy limits indiscriminate fluid administration as it may cause congestive heart failure and pulmonary edema. We have described the fluid therapy algorithm based on the plethysmography variability index and velocity time integral at the left ventricular outflow tract, which was able to limit excessive fluid administration and maintain adequate perfusion pressures.

BACKGROUND: Transurethral resection of bladder tumors (TURBT) surgeries requires post-resection catheterization for continuous irrigation of the bladder. This indwelling catheter is associated with distressing catheter-related bladder discomfort (CRBD) and increases postoperative pain and agitation. OBJECTIVES: To prove the hypothesis that transurethral 100 mg lidocaine irrigation at the end of TURBT can reduce the frequency of moderate-to-severe postoperative CRBD. METHODS: 116 patients scheduled for TURBT were screened, 94 were recruited and completed the study. American Society of Anesthesiologists Physical Status I-II adult patients, 20-75 years of age undergoing elective TURBT surgery under general anesthesia were included. Transurethral normal saline with 0.01% lidocaine (100 mg in 1 L NS) was used for irrigation 30 min before the completion of surgery in group L, while only normal saline was used for transurethral irrigation in group N. The main outcomes were frequency of CRBD, pain and patient satisfaction at 0, 1, 2, and 6 h postoperatively. RESULTS: A total of 94 patients were analyzed in the study. The incidence of moderate-severe CRBD was significantly lower in group L as compared to group C at 0, 1, and 2 h (65.9% vs. 31.9%, p = 0.01; 31.9% vs. 10.6%, p = 0.012; 21.3% vs. 2.1%, p = 0.004, respectively). At the 6-h mark, the incidence of CRBD was lower in group L, although this did not achieve statistical significance (6.38% vs. 2.1%; p = 0.613). CONCLUSION: Irrigation with 0.01% lidocaine (100 mg) towards the end of TURBT reduces the incidence of moderate-severe CRBD by 52% and increases patient satisfaction.

Double-outlet right ventricle (DORV) is a rare cardiac condition in which both the aorta and pulmonary artery arise from the right ventricle, resulting in parallel systemic and pulmonary circulations. Usually, DORV is present with ventricular septal defect; however, the location of the ventricular septal defect and presence of pulmonary stenosis (PS) result in various physiological features and subtypes of DORV. Because DORV without PS causes congestive cardiac failure and DORV with PS results in cyanotic heart disease, anesthesia management varies widely according to the resultant physiological characteristics. Reports of anesthesia management in a parturient with DORV undergoing cesarean delivery is scarce because of the low incidence of DORV and the discouragement of these patients to conceive. Only 8 known previous such cases are reported, and almost all these patients were administered regional anesthesia. Here we describe a parturient with DORV, to whom general anesthesia was administered because of incidental antiphospholipid syndrome with low platelets. To the best of our knowledge, this scenario has not been described previously.

BACKGROUND: Efficacy of high-flow nasal cannula (HFNC) over noninvasive ventilation (NIV) in severe coronavirus disease 2019 (COVID-19) pneumonia is not known. We aimed to assess the incidence of invasive mechanical ventilation in patients with acute hypoxemic respiratory failure due to COVID-19 treated with either HFNC or NIV. METHODS: This was a single-center randomized controlled trial performed in the COVID-19 ICU of a tertiary care teaching hospital in New Delhi, India. One hundred and nine subjects with severe COVID-19 pneumonia presenting with acute hypoxemic respiratory failure were recruited and allocated to either HFNC (n = 55) or NIV (n = 54) arm. Primary outcome was intubation by 48 h. Secondary outcomes were improvement in oxygenation by 48 h, intubation rate at day 7, and in-hospital mortality. RESULTS: Baseline characteristics and [Formula: see text]/[Formula: see text] ratio were similar in both the groups. Intubation rate at 48 h was similar between the groups (33% NIV vs 20% HFNC, relative risk 0.6, 95% CI 0.31-1.15, P = .12). Intubation rate at day 7 was lower in the HFNC (27.27%) compared to the NIV group (46.29%) (relative risk 0.59, 95% CI 0.35-0.99, P = .045), and this difference remained significant after adjustment for the incidence of chronic kidney disease and the arterial pH (adjusted OR 0.40, 95% CI 0.17-0.93, P = .03). Hospital mortality was similar between HFNC (29.1%) and NIV (46.2%) group (relative risk 0.6, 95% CI 0.38-1.04, P = .06). CONCLUSIONS: We were not able to demonstrate a statistically significant improvement of oxygenation parameters nor of the intubation rate at 48 h between NIV and HFNC. These findings should be further tested in a larger randomized controlled trial. The study was registered at the Clinical Trials Registry of India (www.ctri.nic.in; reference number: CTRI/2020/07/026835) on July 27, 2020.

BACKGROUND & OBJECTIVES: In this study we describe the epidemiological data, comorbidities, clinical symptoms, severity of illness and early outcome of patients with coronavirus disease 2019 (COVID-19) from a tertiary care teaching hospital in New Delhi, India. METHODS: In this preliminary analysis of a prospective observational study, all adult patients admitted to the screening intensive care unit (ICU) of the institute who fulfilled the WHO case definition of COVID-19 and confirmed to have SARS-CoV-2 infection by reverse transcription-polymerase chain reaction were included. Demographics, clinical data and 24 h outcome were assessed. RESULTS: The preliminary analysis of 235 patients revealed that the mean age was 50.7±15.1 yr and 68.1 per cent were male. Fever (68.1%), cough (59.6%) and shortness of breath (71.9%) were the most common presenting symptoms. Hypertension (28.1%) and diabetes mellitus (23.3%) were the most common associated comorbid illnesses. Patients with mild, moderate, severe and critical illness were 18.3, 32.3, 31.1 and 18.3 per cent, respectively, at the time of ICU admission. The proportions (95% confidence interval) of patients requiring any form of oxygen therapy, oxygen therapy by high-flow nasal cannula and invasive mechanical ventilation were 77, 21.7 and 25.5 per cent, respectively, within 24 h of hospital admission. The 24 h ICU mortality was 8.5 per cent, and non-survivors had higher respiratory rate (P <0.01, n=198) and lower baseline oxyhaemoglobin saturation (P <0.001, n=198) at presentation and higher baseline serum lactate (P <0.01, n=122), total leucocyte count (P <0.001, n=186), absolute neutrophil count (P <0.001, n=132), prothrombin time (P <0.05, n=54) and INR (P <0.05, n=54) compared to survivors. INTERPRETATION & CONCLUSIONS: Nearly half of the patients presented with severe and critical disease and required high-flow nasal oxygen or invasive mechanical ventilation at admission. Severity of the presenting respiratory illness, haematological parameters and lactate rather than age or presence of comorbidity predicted early death within 24 h.

BACKGROUND: Postintubation sequels (PIS) are a cause of serious concern in the postoperative period. AIM: The aim of this study is to find the influence of preoperative inhaled steroid and technique of muscle relaxation on PIS. SETTINGS AND DESIGN: This prospective, exploratory pilot study was conducted on 120 adult American Society of Anesthesiologist physical status Class I and II patients undergoing general anesthesia (GA) with muscle relaxation and cuffed endotracheal tube (ETT) insertion. PATIENTS AND METHODS: Patients were randomized into four groups as follows: intermittent muscle relaxation with preanesthetic inhalation of either distilled water puffs (Group ID) or fluticasone puffs (Group IF); continuous infusion of muscle relaxant with preanesthetic inhalation of either distilled water puffs (Group CD) or fluticasone puffs (Group CF). After induction of GA, ETT was inserted. The intra-cuff pressure was maintained constant. The trachea was extubated in the light plane in intermittent groups and in the deep plane in continuous groups. STATISTICAL ANALYSIS: Qualitative parameters were compared using the Chi-square test and quantitative parameters using repeated measure ANOVA followed by Tukey's test. RESULTS: Group CF had significantly less incidence of sore throat and hoarseness compared to groups ID and IF. The severity of sore throat was more in groups ID and IF than in groups CF and CD (P < 0.002). The severity of hoarseness was least in group CF (23.3%) and highest in group IF (90%). None of the patients had a cough in group CF. The incidence and severity of dysphagia were significantly less in group CF as compared to other groups (P < 0.005 and P < 0.008, respectively). CONCLUSION: Continuous infusion of muscle relaxant with extubation in deep plane of anesthesia with preanesthetic inhalation of fluticasone puffs results in lesser incidence and severity of PIS.
