RESUMEN
Background India has a disproportionately lower rate of coronavirus disease 2019 (COVID-19) severe disease and lower death rates with respect to other parts of the world. It has been proposed that malaria-endemic countries such as India are relatively protected against severe COVID-19 disease and deaths. Methods This was a cross-sectional, analytical, observational study conducted from August 2020 to July 2021 at a tertiary care COVID-19-designated center in New Delhi, India. It aimed to study the association between antimalarial antibody levels and COVID-19 disease severity and outcomes. Results One hundred forty-six patients were included in the final analysis. The mean (standard deviation {SD}) age of the study population was 44.6 (17.2) years, and there were 85 (58.2%) males. Sixty-five patients had mild disease, 14 patients had moderate disease, and 67 patients had severe disease at the time of enrolment in the study. Forty-six patients expired during the hospital stay. For the antimalarial antibody, there was a statistically significant difference between mild and moderate (p=0.018), mild and severe (p=0.016), and mild and combined moderate and severe diseases (p=0.013). However, there was no difference between the patients who survived and those who did not. Conclusion Antimalarial antibody levels may not be associated with the outcomes of COVID-19 during hospital stay. However, this study has provided some insights into the relationship between the severity and outcomes of COVID-19 and the levels of antimalarial antibodies.
RESUMEN
The purpose of this meta-analysis was to evaluate the efficacy of nebulised magnesium in the treatment of acute exacerbation of COPD. PubMed and Embase databases were searched for randomised controlled trials comparing any dose of nebulised magnesium sulphate with placebo for treatment of acute exacerbation of COPD, published from database inception till 30 June 2022. Bibliographic mining of relevant results was performed to identify any additional studies. Data extraction and analyses were done independently by review authors and any disagreements were resolved through consensus. Meta-analysis was done using a fixed-effect model at clinically significant congruent time points reported across maximum studies to ensure comparability of treatment effect. Four studies met the inclusion criteria, randomly assigning 433 patients to the comparisons of interest in this review. Pooled analysis showed that nebulised magnesium sulphate improved pulmonary expiratory flow function at 60 minutes after initiation of intervention compared to placebo [median difference (MD) 9.17%, 95% confidence interval (CI) 2.94 to 15.41]. Analysis of expiratory function in terms of standardised mean differences (SMD) revealed a small yet significant positive effect size (SMD 0.24, 95% CI 0.04 to 0.43). Among the secondary outcomes, nebulised magnesium sulphate reduced the need for ICU admission (risk ratio 0.52, 95% CI 0.28 to 0.95), amounting to 61 fewer ICU admissions per 1000 patients. No difference was noted in the need for hospital admission, need for ventilatory support, or mortality. No adverse events were reported. Nebulised magnesium sulphate improves pulmonary expiratory flow function and reduces the need for ICU admission in patients with acute exacerbation of COPD.
RESUMEN
Wilson's disease (WD) is a disorder of copper metabolism presenting with a wide variety of organ dysfunctions affecting predominantly the neurological, hepatic, and hematological systems. Due to its multi-systemic nature, administering anesthesia to a patient with WD is challenging and requires an in-depth knowledge of the disease pathophysiology. A systematic search for literature pertaining to the anesthetic management of patients with WD yielded 19 case reports, which we have included in this review to explore and summarize peri-operative concerns and the safe anesthesia practices in this condition.
RESUMEN
BACKGROUND: Optimum procedural sedation is very essential for conducting non-operating room procedures such as endoscopic retrograde cholangiopancreatography (ERCP). The combination of ketamine and dexmedetomidine (KD) is expected to balance out the undesirable effects of either drug and provide smooth sedation. Together ketamine and propofol (KP) also provide synergistic sedation with stable hemodynamics. This prospective, single-blinded randomized study aimed to compare the effect of both the combinations during ERCP in terms of oxygen desaturation, respiratory depression, hemodynamic parameters, analgesia, recovery time, and ease with which the endoscopist could perform the endoscopy. METHODS: This prospective, single-blinded randomized study (CTRI/2019/08/020625) was conducted on 84, ASA (American Society of Anesthesiologists) physical status I or II patients, of age 18-65 years presenting for ERCP in a tertiary care center. They were randomized to receive either KD (n=42) or KP (n=42) combination during ERCP. Mean SPO2 at the end of the procedure was compared between the groups. Apart from these periprocedural hemodynamic and respiratory parameters, pain scores on arrival in the recovery room (t0), 15 minutes (t15), and 30 minutes (t30), recovery time, and endoscopist's satisfaction as per a Likert's scale were recorded. RESULTS: The mean SpO2 (SpO2 recorded every minute during the procedure and averaged over procedure time in minutes) in group KP (97.7 [96.1-98.6]) was significantly lower than group KD (98.5 [98.1-98.8]) (p=0.005). The post-procedure pain scores measured at t0 and t15 were higher in group KP (p<0.001 and p=0.043), and comparable at t30 in both the groups (p=0.711). The time to achieve Modified Aldrete score (MAS) ≥ 9 was significantly more in group KD (p<0.001). The lowest mean arterial pressure and heart rate in group KD were significantly lower than in group KP (p<0.001, p=0.006, respectively). The overall endoscopist satisfaction was better in group KP compared to group KD (p= 0.011). CONCLUSIONS: The combination of ketamine-dexmedetomidine for procedural sedation during ERCP is a safe alternative to ketamine-propofol with a better respiratory profile.

Critically ill burn patients pose several unique challenges to care providers. The concepts of fluid resuscitation, nutritional management, organ support and wound care are rapidly evolving. There is a pressing need to review emerging evidence and incorporate these into practice for the effective management of burn patients. We have searched the PubMed and Google Scholar databases to review the current evidence on the acute care management of adult as well as paediatric burn patients. The rationales for current practices have been integrated into the review. The management of critically ill burn patients requires an in-depth knowledge of the pathophysiology of burn injury, a tailored approach for timely resuscitation, timely diagnosis of organ specific problems, and comprehensive wound care. This review will help the doctors and healthcare providers involved in the management of critical burn patients in their day-to-day practice.
RESUMEN
Background In the wake of the recent Roe vs. Wade judgment, we performed a Google Trends analysis to identify the impact of this decision on the interests regarding contraceptive choices in the United States. Methods A Google Trends search between April 6 and July 5, 2022, with the United States as the area of interest, was performed using the five most popular contraception choices. In addition, a second trend search was performed using oral and injectable hormonal birth control measures. Results Trends showed a spike in interest regarding various contraceptive methods immediately following the verdict. The highest increase in interest was noted for "vasectomy," followed by "tubal ligation." With respect to oral and injectable birth control measures, "morning after pill" showed a marked spike in interest. Conclusion This verdict has triggered increased interest in contraceptive practices, which can be translated into better reproductive health with proper public health initiatives.
RESUMEN
ProSeal laryngeal mask airway (PLMA) insertion is often difficult. Suction catheter-guided PLMA insertion was compared with the standard introducer tool-assisted technique. One hundred sixty female patients undergoing laparoscopic gynecologic procedures under general anesthesia were randomized into two groups-the suction catheter group (Group SC) and the introducer tool group (Group IT). First-attempt success rate, insertion time, manipulation required, incidence of trauma, and incidence and severity of throat discomfort were compared. PLMA was inserted successfully in the first attempt in 72 of 80 patients in Group SC and in 67 of 80 patients in Group IT (P = .241). Time for successful insertion was 17.31 ± 6.50 seconds in Group SC and 22.65 ± 7.17 seconds in Group IT (P = .001). Manipulation to get a proper fit was required in 9 of 80 patients in Group SC compared with 19 of 80 patients in Group IT (P = .037). Minor airway trauma was noted in 11% of patients in Group SC and 28% of patients in Group IT (P = .001). The incidence and severity of sore throat was significantly lower with the suction catheter than with the introducer tool. Suction catheter-guided PLMA insertion requires less time, fewer manipulations, and results in lower incidence and severity of sore throat than with the introducer tool. Both techniques have a similar first-attempt success rate.

The authors describe a case series of co-infection with COVID-19 and scrub typhus in two Indian patients. Clinical features like fever, cough, dyspnea and altered sensorium were common in both patients. Case 1 had lymphopenia, elevated IL-6 and history of hypertension, while case 2 had leukocytosis and an increased liver enzymes. Both patients had hypoalbuminemia and required admission to the intensive care unit; one of them succumbed to acute respiratory distress syndrome further complicated by multiple organ dysfunction syndrome. Seasonal tropical infections in COVID-19 patients in endemic settings may lead to significant morbidity and mortality. Therefore, high clinical suspicion and an early diagnosis for co-infections among COVID-19 patients are essential for better patient management.

Emerging evidence shows co-infection with atypical bacteria in coronavirus disease 2019 (COVID-19) patients. Respiratory illness caused by atypical bacteria such as Mycoplasma pneumoniae, Chlamydia pneumoniae, and Legionella pneumophila may show overlapping manifestations and imaging features with COVID-19 causing clinical and laboratory diagnostic issues. We conducted a prospective study to identify co-infections with SARS-CoV-2 and atypical bacteria in an Indian tertiary hospital. From June 2020 to January 2021, a total of 194 patients with laboratory-confirmed COVID-19 were also tested for atypical bacterial pathogens. For diagnosing M. pneumoniae, a real-time polymerase chain reaction (PCR) assay and serology (IgM ELISA) were performed. C. pneumoniae diagnosis was made based on IgM serology. L. pneumophila diagnosis was based on PCR or urinary antigen testing. Clinical and epidemiological features of SARS-CoV-2 and atypical bacteria-positive and -negative patient groups were compared. Of the 194 patients admitted with COVID-19, 17 (8.8%) were also diagnosed with M. pneumoniae (n = 10) or C. pneumoniae infection (n = 7). Confusion, headache, and bilateral infiltrate were found more frequently in the SARS CoV-2 and atypical bacteria co-infection group. Patients in the M. pneumoniae or C. pneumoniae co-infection group were more likely to develop ARDS, required ventilatory support, had a longer hospital length of stay, and higher fatality rate compared to patients with only SARS-CoV-2. Our report highlights co-infection with bacteria causing atypical pneumonia should be considered in patients with SARS-CoV-2 depending on the clinical context. Timely identification of co-existing pathogens can provide pathogen-targeted treatment and prevent fatal outcomes of patients infected with SARS-CoV-2 during the current pandemic.

BACKGROUND AND AIMS: We describe the epidemiological and clinical characteristics, and 28 day outcome of critically ill COVID-19 patients admitted to a tertiary care centre in India. MATERIAL AND METHODS: We included 60 adult critically ill COVID-19 patients in this prospective observational study, admitted to the intensive care unit (ICU) after obtaining ethics committee approval and informed consent. Demographics, clinical data, and treatment outcome at 28 days were assessed. RESULTS: Demographic characteristics of the COVID-19 patients reveal that compared to the survivors, the non-survivors were significantly older [57.5 vs. 47.5 years], had more comorbid disease [Charlson's comorbidity index 4 vs. 2], higher Apache II scores [19 vs. 8.5], and had significantly higher percentage of smokers. Diabetes mellitus and hypertension were the most common comorbidities. Dyspnea, fever, and cough were the most common presenting symptoms. Total leucocyte count as well as blood lactate level were significantly higher in non-survivors. Around 47% patients had severe ARDS, and 60% patients required invasive mechanical ventilation. 28 day ICU mortality was 50%, with a mortality of 75% in patients receiving invasive mechanical ventilation. Mortality was higher in males than females (57% vs. 33%). Acute kidney injury and septic shock were the most common non-pulmonary complications during ICU stay. Incidence of liver dysfunction, septic shock, and vasopressor use was significantly higher in the non-survivors. CONCLUSION: This study demonstrates a high 28 day mortality in severe COVID-19 patients. Further well designed prospective studies with larger sample size are needed to identify the risk factors associated with poor outcome in such patients.
RESUMEN
Persistent tachycardia in patients with septic shock predicts poor outcome. This study sought to investigate the effect of the cardiac pacemaker current inhibitor ivabradine on heart rate and cardio-circulatory function in patients with septic shock. After informed consent, 60 patients with septic shock and persistent tachycardia (heart rate >95 /minute) were prospectively randomly assigned to receive either standard therapy for septic shock (group S) or standard therapy along with enteral ivabradine (group I) for the initial 96 hours after enrolment. Primary outcome was the difference in heart rate between the two groups during the first 96 hours. Secondary outcomes included the effect of ivabradine on haemodynamic, oxygenation, myocardial function and organ function parameters, incidence of adverse events and 30-day overall survival. Heart rate was lower in group I compared to group S (median difference in area under the curve -25.6 (95% confidence intervals -31.4 to -15.9) /minute; P <0.001). Vasopressor requirements, blood lactate levels, Sequential Organ Failure Assessment scores and E/e' ratio were lower in group I compared to group S. Stroke volume index and ejection fraction were higher in group I while cardiac index and oxygen delivery parameters were maintained similar to group S. There was no difference in 30-day mortality or in the incidence of serious adverse events. Enteral ivabradine is effective in reducing heart rate, and improving haemodynamic parameters and cardiac function in patients with septic shock and persistent tachycardia, without increasing the incidence of adverse events.

BACKGROUND AND OBJECTIVE: A large number of studies describing the clinicoepidemiological features of coronavirus disease-2019 (COVID-19) patients are available but very few studies have documented similar features of the deceased. This study was aimed to describe the clinicoepidemiological features and the causes of mortality of COVID-19 deceased patients admitted in a dedicated COVID center in India. METHODOLOGY: This was a retrospective study done in adult deceased patients admitted in COVID ICU from April 4 to July 24, 2020. The clinical features, comorbidities, complications, and causes of mortality in these patients were analyzed. Pediatric deceased were analyzed separately. RESULTS: A total of 654 adult patients were admitted in the ICU during the study period and ICU mortality was 37.7% (247/654). Among the adult deceased, 65.9% were males with a median age of 56 years [interquartile range (IQR), 41.5-65] and 94.74% had one or more comorbidities, most common being hypertension (43.3%), diabetes mellitus (34.8%), and chronic kidney disease (20.6%). The most common presenting features in these deceased were fever (75.7%), cough (68.8%), and shortness of breath (67.6%). The mean initial sequential organ failure assessment score was 9.3 ± 4.7 and 24.2% were already intubated at the time of admission. The median duration of hospital stay was 6 days (IQR, 3-11). The most common cause of death was sepsis with multi-organ failure (55.1%) followed by severe acute respiratory distress syndrome (ARDS) (25.5%). All pediatric deceased had comorbid conditions and the most common cause of death in this group was severe ARDS. CONCLUSION: In this cohort of adult deceased, most were young males with age less than 65 years with one or more comorbidities, hypertension being the most common. Only 5% of the deceased had no comorbidities. Sepsis with multi-organ dysfunction syndrome was the most common cause of death.

RESUMEN
Klippel-Feil syndrome (KFS) is a rare congenital anomaly that is characterized by short neck, low posterior hairline, and restricted neck movements, all of which lead to the possibility of a difficult airway. These patients often have associated multiple systemic anomalies, which add to the challenges in anesthetic management. We describe the anesthetic management of 3 patients with KFS: 2 who underwent modified radical mastoidectomy and 1 patient who underwent vaginoplasty at our institute. Careful planning and preparedness for difficult airway and thorough knowledge of associated comorbidities are key to successful management of patients with KFS.

Purpose: A videolaryngoscope has been recommended for intubation in the COVID-19 scenario but the videolaryngoscope providing optimal intubation conditions is not ascertained. We compared KingVision channelled blade with a non-Channelled videolaryngoscope for intubation times in a simulated COVID-19 intubation scenario by both anaesthesiologists and non-anaesthesiologists. Methods: This prospective randomised cross over mannequin study was conducted in a skill training lab. 25 anaesthesiologists and 25 non-anaesthesiologists donned in standard personal protective equipment performed 100 intubations with KingVision and Tuoren videolaryngoscopes in a mannequin covered with a transparent plastic sheet. The total intubation time, percentage of glottic opening scores, first attempt success rates were assessed. Results: The mean difference in intubation times in anaesthesiologists and non-anaesthesiologist less with KingVision videolaryngoscope (21.1s; 95% CI 9.6-32.6s vs. 35.9s; 95% CI 24.4-47.4 s; P = 0.001). Percentage of glottic opening score was significantly better with KingVision by non-anaesthesiologists (60; IQR 42.5 to 75 vs. 70; IQR 50 to 100; P = 0.019). KingVision provided superior first attempt success rate in non-anaesthesiologists (84% vs. 61.9%; P = 0.02) and anaesthesiologists (96% vs. 76%; P = 0.12). Conclusion: KingVision channelled videolaryngoscope provided faster intubation times, glottic views and first attempt success rates in a simulated COVID-19 scenario in manikins and might be preferred over videolaryngoscopes with non-channelled blade. The findings need to be further verified in humans. Trial registration: ctri.nic.in identifier: REF/2020/05/033338.
RESUMEN
BACKGROUND: Although sevoflurane is preferred for inhalational induction in children, financial and environmental costs remain major limitations. The aim of this study was to determine if the use of low-fresh gas flow during inhalational induction with sevoflurane could significantly reduce agent consumption, without adversely affecting induction conditions. METHODS: After institutional ethical committee approval, 50 children, aged 1-5 years, undergoing ophthalmic procedures under general anesthesia, were randomized into two groups-standard induction (Group S) and low-flow induction (Group L). A pediatric circle system with 1 L reservoir bag was primed with 8% sevoflurane in oxygen at 6 L min-1 for 30 seconds before beginning induction. In Group S, fresh gas flow was maintained at 6 L min-1 until the end of induction. In Group L, fresh gas flow was reduced to 1 L min-1 after applying facemask (time = T0). In both groups, sevoflurane was reduced to 5% after loss of eyelash reflex (T1). Once adequate depth of anesthesia was achieved (regular respiration, loss of muscle tone, and absence of movement to trapezius squeeze), intravenous access was secured (T2), followed by insertion of an appropriately sized LMA-Classic™ (T3). Heart rate and endtidal sevoflurane concentration were measured at each of the above time points, and at 15 seconds following laryngeal mask airway insertion (T4). The total amount of sevoflurane consumed during induction was recorded. RESULTS: Sevoflurane consumption was significantly lower in Group L (4.17 ± 0.70 mL) compared to Group S (8.96 ± 1.11 mL) (mean difference 4.79 [95% CI = 4.25-5.33] mL; P < 0.001). Time to successful laryngeal mask airway insertion was similar in both groups. There were no significant differences in heart rate, incidence of reflex tachycardia, or need for rescue propofol. CONCLUSION: Induction of anesthesia with sevoflurane using low-fresh gas flow is effective in reducing sevoflurane consumption, without compromising induction time and conditions.

BACKGROUND: Minute ventilation (MV) and calorific requirement (CR) are both functions of metabolic demand. The Holliday-Segar formula is a weight-based tool for predicting CR. This study was performed to derive an equation, based on the Holliday-Segar formula, for calculating resting MV from body-weight (BW), which is applicable for all age groups. METHODS: MV for BW (obtained from Radford normogram) was plotted against CR for BW (as per Holliday-Segar formula), for BWs ranging from neonates to adults. From the scatter plot thus obtained, best-fit line, with the origin as intercept, was drawn. Linear regression analysis was used to obtain R2 coefficient and P value. RESULTS: The plot of MV against CR yields a straight line passing through the origin with a slope = 46.87. R2 value is 0.98886, P < 0.001. CONCLUSION: MV can be easily and reliably estimated for all age groups from the equation: MV (mL/min) = 47 × CR (kcal/h).
