RESUMEN
Background: Nitrous oxide has been an integral part of surgical anesthesia for many years in the developed world and is still used in developing countries such as India. The other main concerns in low-resource countries are the lack of an advanced anesthesia gas-scavenging system and modular surgical theatres. As a greenhouse gas that has been present in the atmosphere for more than 100 years and damages the ozone layer, nitrous oxide is three times worse than sevoflurane. Here, we conducted an observational study to quantify the annual nitrous oxide consumption and its environmental impact in terms of carbon dioxide equivalence in one of busiest tertiary health care and research centers in Northern India. Methods: Data related to nitrous oxide expenditure' from the operation theatre and manifold complex of our tertiary care hospital and research center from 2018 to 2021 were collected monthly and analyzed. The outcomes were extracted from our observational study, which was approved by our institutional ethics board (INT/IEC/2017/1372 Dated 25.11.2017) and registered prospectively under the Central Registry (CTRI/2018/07/014745 Dated 05.07.2018). Results: The annual nitrous oxide consumption in our tertiary care hospital was 22,081.00, 22,904.00, 17,456.00, and 18,392.00 m3 (cubic meters) in 2018, 2019, 2020, and 2021, respectively. This indicates that the environmental impact of nitrous oxide (in terms of CO2 equivalents) from our hospital in 2018, 2019, 2020, and 2021 was 13,016.64, 13,287.82, 10,289.94, and 10,841.24 tons, respectively. Conclusion: This huge amount of nitrous oxide splurge is no longer a matter of laughter, and serious efforts should be made at every central and peripheral health center level to reduce it.
RESUMEN
BACKGROUND: efficacy of therapeutic cholecalciferol supplementation for severe COVID-19 is sparingly studied. OBJECTIVE: effect of single high-dose cholecalciferol supplementation on sequential organ failure assessment (SOFA) score in moderate-to-severe COVID-19. METHODS: participants with moderate to severe COVID-19 with PaO2/FiO2 ratio < 200 were randomized to 0.6 million IU cholecalciferol oral (intervention) or placebo. OUTCOMES: primary outcome was change in Day 7 SOFA score and pre-specified secondary outcomes were SOFA and 28-day all-cause mortality. RESULTS: in all, 90 patients (45 each group) were included for intention-to-treat analysis. 25(OH)D3 levels were 12 (10-16) and 13 (12-18) ng/ml (P = 0.06) at baseline; and 60 (55-65) ng/ml and 4 (1-7) ng/ml by Day 7 in vitamin D and placebo groups, respectively. The SOFA score on Day 7 was better in the vitamin D group [3 (95% CI, 2-5) versus 5 (95% CI, 3-7), P = 0.01, intergroup difference - 2 (95% CI, -4 to -0.01); r = 0.4]. A lower all-cause 28-day mortality [24% compared to 44% (P = 0.046)] was observed with vitamin D. CONCLUSIONS: single high-dose oral cholecalciferol supplementation on ICU admission can improve SOFA score at Day 7 and reduce in-hospital mortality in vitamin D-deficient COVID-19. ClinicalTrials.gov id: NCT04952857 registered dated 7 July 2021. What is already known on this topic-vitamin D has immunomodulatory role. Observational and isolated intervention studies show some benefit in COVID-19. Targeted therapeutic vitamin D supplementation improve outcomes in severe COVID-19 is not studied in RCTs. What this study adds-high-dose vitamin D supplementation (0.6 Million IU) to increase 25(OH)D > 50 ng/ml is safe and reduces sequential organ failure assessment score, in-hospital mortality in moderate to severe COVID-19. How this study might affect research, practice or policy-vitamin D supplementation in vitamin D-deficient patients with severe COVID-19 is useful may be practiced.

Objective: The stress response following traumatic brain injury (TBI) is a preventable cause of secondary brain injury. This can be prevented using sedation in the intensive care unit (ICU). To date, the choice of sedative agent for preventing stress response is not well-studied in literature. Methods: This prospective randomized controlled trial included 60 patients with severe TBI admitted to ICU. The patients were randomized into 2 study groups according to the choice of sedation: propofol (group I) and midazolam infusion (group II). The serum cortisol was measured as the primary outcome at admission to ICU and 48 hours following sedation infusion. The baseline Glasgow coma scale, hemodynamic, optic nerve sheath diameter (ONSD), and computed tomography scan findings were noted at admission. Glasgow outcome scale (GOS) was measured as a neurological outcome at discharge from ICU. Results: There was a statistically significant reduction in serum cortisol level in both the study groups (Δ cortisol, p-value=134.91 (50.5,208.2), 0.00 and 118.8 (42.6,160.4), 0.00, in group I and II, respectively). Serum cortisol levels were comparable among both groups at baseline and 48 hours. Similarly, there was a statistically significant difference in ONSD in both groups, but there was no difference in ONSD value between the groups at 48 hours. The GOS was also similar in both groups at discharge from ICU. Conclusion: The study demonstrated a similar reduction in serum cortisol levels following 48 hours of propofol or midazolam infusion in patients with severe TBI.
RESUMEN
BACKGROUND: Submental intubation performed using the classical Altemir's technique is a well-accepted, safe technique for providing optimal operating field to the maxillofacial surgeon, in cases where either nasotracheal or orotracheal intubation is impossible. We propose a new, percutaneous Seldinger's technique of submental intubation as an interesting alternative to the classical Altemir's technique, wherein a percutaneous dilatational tracheostomy kit is used to dilate the submental tract, instead of bluntly dissecting it. We hypothesized that Seldinger's technique would be associated with reduced procedure time and minimal scar formation in patients with maxillofacial fractures. METHODS: We enrolled 60 patients scheduled to undergo maxillofacial injury fixation under general anesthesia. After consent, the cohort was randomly allocated to undergo submental intubation by either the classical Altemir's technique or Seldinger's technique. As our primary objective, we noted the time taken to complete the procedure of submental intubation. Our secondary objectives were the components of primary outcome, such as disconnection/apnea time, bleeding, and technical difficulties during the procedure. We also observed for complications such as presence of salivary fistula/infection at hospital discharge and scar characteristics at 1- and 3-month follow-up. RESULTS: The median time for performing submental intubation in the Seldinger group was significantly lower than that in the Altemir group (170.5 [136.5-256.0] seconds vs 220.0 [205.5-289.0] seconds; P value, .040). The median disconnection time was also significantly lower in the Seldinger group (12.0 [10.8-20.0] seconds vs 19.0 [15.0-23.0] seconds; P value, .036). Furthermore, significant bleeding was absent in nearly 53.8% of the study participants in the Seldinger group as compared to 25.9% in the Altemir group. At follow-up, there was no evidence of differences in scar characteristics between the 2 groups. CONCLUSIONS: Seldinger's technique is associated with shorter procedure time and reduced apnea time due to easier and better tract formation, thus minimizing the effort required to exteriorize the endotracheal tube. Furthermore, as dilation reduces tissue damage, Seldinger's technique is associated with significantly less procedural bleeding. Thus, Seldinger's technique can be safe, easy, and faster to perform compared with the classical Altemir's technique of submental intubation in patients with maxillofacial trauma.

Background Extubation has always been a critical aspect of anaesthesia. Guidelines and recommendations are in place for achieving successful extubation, but the risk of failure always persists. Through this study, we assess whether arterial blood gas (ABG) values taken intraoperatively help predict extubation success in the operation theatre. Materials and methods This was a prospective observational study for one year of extubated patients whose blood gas values were not within the normal range. The patients of age 18 years and above undergoing high-risk elective and emergency surgeries where at least one intraoperative arterial blood sample was taken for blood gas analysis were included. Apart from parameters of ABG demographic data, urgency and duration of surgery, blood loss, urine output, use of intraoperative fluid(s), and blood product(s) were also observed. Results Of 578 patients enrolled, 116 patients were extubated based on the predefined extubation criteria. Of these, 24 patients were reintubated within 24 hours. ABG parameters such as partial pressure of arterial oxygen (PaO2) and serum HCO3- levels were significantly lower in the reintubated patients compared to non-reintubated patients (p-values of 0.045 and 0.003, respectively). Conclusion This study showed that the PaO2 <100 mm Hg or ratio of arterial oxygen partial pressure to fractional inspired oxygen (P/F ratio) of less than 200 and an HCO3- value of less than 18 are plausible ABG parameters to decide extubation in post-surgery patients in OT. PaCO2, base deficit, and lactate were less reliable parameters for planning extubation.
RESUMEN
Trans-nasal endoscopic surgery (TNES) is a helpful diagnostic and therapeutic modality in otorhinolaryngology surgeries and requires controlled hypotension for better visualization of the surgical field. Recent literature shows evidence of intravenous Lignocaine infusion to produce the controlled hypotension. The study aims to assess and compare the effects of Lignocaine (LIG) and Dexmedetomidine (DEX) infusion with respect to surgical field quality. 101 Consenting adult patients undergoing elective TNES were double-blinded, randomly allocated in one of the two groups and received either DEX infusion of 0.5ug/kg/hr (n = 51) or LIG infusion of 1.5 mg/kg/h (n = 50) after a loading dose. Surgical field score (SVF) as the primary outcome and secondary outcomes such as variations in hemodynamic parameters, the requirement for rescue agents and total blood loss were recorded. Both the groups were comparable with respect to patient demographics, total duration of anesthesia and surgery. SVF scores were significantly better in the LIG group during the first 105 min of the surgery (p < 0.05). In response to intubation, hemodynamic parameters were lower in LIG group. The requirement of other adjuvant drugs, total blood loss (166.40 ml vs. 251.17 ml) and extubation time were also significantly lower in the LIG group. The study concludes that intravenous Lignocaine gives a better surgical field in the first 105 min of surgery, comparable hemodynamics and decreased blood loss in patients undergoing TNES as compared to Dexmedetomidine infusion. Hence its role as an agent for controlled hypotension during TNES surgery is promising.
RESUMEN
Background and objectives Inadvertent perioperative hypothermia is expected in the elderly during central neuraxial anesthesia. We aimed to compare the incidence of intraoperative hypothermia (< 36-degree celsius) between preoperative forced-air warming for 30 minutes and non-warming groups. Also, we compared the time to develop hypothermia, perioperative shivering, duration of intraoperative active warming, metabolic acidosis, surgical site infections, coagulation derangements, and post-anesthesia care unit (PACU) stay. Material and methodology A total of 100 American Society of Anesthesiologists (ASA) I-III (Age > 60 years) patients scheduled to undergo femur fracture surgeries under central neuraxial anesthesia were enrolled in this single-blinded prospective randomized study. They were randomly allocated into Group A (active forced-air warming for 30 minutes in the preoperative period) and Group B (without forced-air warming). Then, patients were transferred to the operation theatre, where central neuraxial anesthesia was administered for surgery. An infrared tympanic membrane thermometer measured the core body temperature during the different study points. Results The intraoperative hypothermia incidences were 26.0% and 68.0% in groups A and B, respectively. The mean time for developing hypothermia was found to be 143.08 ± 26.26 min and 25.88 ± 9.25 min in groups A and B, respectively. The mean duration of intraoperative active warming was observed to be 15.6 minutes and 103.6 minutes in groups A and B, respectively. The shivering and surgical site infection (SSI) grades were lower in group A. Conclusion A preoperative forced-air warming strategy for 30 minutes helps in reducing the incidence of intraoperative hypothermia and shivering in elderly patients undergoing femur fracture surgeries under central neuraxial anesthesia.
RESUMEN
Background & objectives: The high mortality associated with the thrombotic events in hospitalized COVID-19 patients resulted in the usage of anticoagulants in varying doses. Whether high-dose anticoagulants have led to better outcomes or higher incidence of clinically significant bleeding events is debatable. Thus, this study was conducted to find the incidence of clinically significant bleeding events in moderate-to-severe COVID-19 ARDS (acute respiratory distress syndrome) patients on therapeutic anticoagulation and their outcomes. Methods: In this retrospective, single-centre study of 155 critically ill COVID-19 patients, the incidence of clinically significant bleeding was observed. Multivariate regression models were used to evaluate the association between anticoagulant regimen, coagulation and inflammatory markers with the incidence of bleeding and thrombotic events. Results: The incidence of clinically relevant non-major bleeding was 33.54 per cent (26.17-41.46%) and major bleeding was 9.03 per cent (5.02-14.69%). The anticoagulation intensity at baseline had a high odds of major bleeding when enoxaparin and dual antiplatelet therapy were used together [adjusted odds ratio OR of 434.09 (3.81-49502.95), P<0.05]. At admission, bleeders had a poorer PaO2/FiO2 ratio with more patients on invasive ventilation. At the time of bleeding, the bleeders had a higher D-dimer, ferritin, C-reactive protein and procalcitonin compared to non-bleeders. The subhazard ratio for death in bleeders was 3.35 (95% confidence interval, 1.97-5.65; P<0.001). Interpretation & conclusions: The incidence of bleeding in critically ill COVID-19 patients on therapeutic anticoagulation may increase with the severity of the disease as well as with concurrent use of dual antiplatelets. Major bleeding may also contribute to higher mortality.

OBJECTIVES: Coagulation changes associated with COVID-19 suggest the presence of a hypercoagulable state with pulmonary microthrombosis and thromboembolic complications. We assessed the dynamic association of COVID-19-related coagulation abnormalities with respiratory failure and mortality. DESIGN: Single-centre, prospective cohort study with descriptive analysis and logistic regression. SETTING: Tertiary care hospital, North India. PARTICIPANTS: Patients with COVID-19 pneumonia requiring intensive care unit (ICU) admission between August 2020 and November 2020. PRIMARY AND SECONDARY OUTCOME MEASURES: We compared the coagulation abnormalities using standard coagulation tests like prothrombin time, D-dimer, platelet count, etc and point-of-care global coagulation test, Sonoclot (glass beaded(gb) and heparinase-treated(h)). Incidence of thromboembolic or bleeding events and presence of endogenous heparinoids were assessed. Cox proportional Hazards test was used to assess the predictors of 28-day mortality. MEASUREMENT: All patients underwent Sonoclot (glass beaded) test at admission apart from the routine investigations. In patients at risk of thromboembolic or bleeding phenomena, paired tests were performed at day 1 and 3 with Sonoclot. Activated clotting time (ACT) <110 s and peak amplitude >75 units were used as the cut-off for hypercoagulable state. Presence of heparin-like effect (HLE) was defined by a correction of ACT ≥40 s in h-Sonoclot. RESULTS: Of 215 patients admitted to ICU, we included 74 treatment naive subjects. A procoagulant profile was seen in 45.5% (n=5), 32.4% (n=11) and 20.7% (n=6) in low-flow, high-flow and invasive ventilation groups. Paired Sonoclot assays in a subgroup of 33 patients demonstrated the presence of HLE in 17 (51.5%) and 20 (62.5%) at day 1 and 3, respectively. HLE (day 1) was noted in 59% of those who bled during the disease course. Mortality was observed only in the invasive ventilation group (16, 55.2%) with overall mortality of 21.6%. HLE predicted the need for mechanical ventilation (HR 1.2 CI 1.04 to 1.4 p=0.00). On multivariate analysis, the presence of HLE (HR 1.01; CI 1.006 to 1.030; p=0.025), increased C reactive protein (HR 1.040; CI 1.020 to 1.090; p=0.014), decreased platelet function (HR 0.901; CI 0.702 to 1.100 p=0.045) predicted mortality at 28days. CONCLUSION: HLE contributed to hypocoagulable effect and associated with the need for invasive ventilation and mortality in patients with severe COVID-19 pneumonia.

BACKGROUND: Traditionally, fluid administration during kidney transplant surgery is guided by central venous pressure (CVP) despite its limited reliability as a parameter for assessing intravascular fluid volume, particularly in patients with cardiovascular diseases. The recommended goals at graft reperfusion are a mean arterial pressure of 90 mm Hg and a CVP of 12-14 mm Hg. This approach may increase the risk of significant adverse effects due to volume overload. Perioperative fluid therapy guided by dynamic indices of fluid responsiveness has been shown to optimize intravascular volume and prevent complications associated with overzealous administration of fluids in major abdominal surgeries. We hypothesized that pulse pressure variation (PPV)-guided fluid administration would result in better optimization of intravascular fluid volume compared with a CVP-guided strategy during kidney transplant surgery. METHODS: In this single-centre randomized double blinded trial, 77 end-stage renal disease patients, who underwent kidney transplant surgery under general anesthesia with epidural analgesia, were randomized to receive either CVP-guided (n = 35) or PPV-guided (n = 35) fluid therapy using predefined hemodynamic endpoints. The primary outcome was the total volume of intraoperative fluids administered. Secondary outcomes were intraoperative hemodynamic changes, serum lactate levels, serum creatinine, need for dialysis within the first week, creatinine elimination ratio, and incidence of immediate and delayed graft dysfunction. RESULTS: Results were analyzed for 70 patients. Eighty percent of the patients underwent living-related donor allograft kidney transplant. Operative variables related to donor characteristics, duration of surgery, graft cold ischemia time, and blood loss were comparable in both groups. The mean (standard deviation) volume of intravenous fluids administered intraoperatively was 1,346 (337) mL in the PPV-guided group vs 1,901 (379) mL in the CVP-guided group (difference in means, 556 mL; 95% confidence interval, 385 to 727; P = 0.001). There were no significant differences in secondary outcomes between the two groups. CONCLUSION: Pulse pressure variation -guided fluid administration significantly decreased the total volume of crystalloids compared with CVP-guided fluid therapy during the intraoperative period in patients who underwent kidney transplant surgery. Nevertheless, our study was underpowered to detect differences in secondary outcomes. TRIAL REGISTRATION: www.ctri.nic.in (CTRI/2018/01/011638); registered 31 January 2018.
RéSUMé: CONTEXTE: Traditionnellement, l'administration liquidienne pendant une chirurgie de transplantation rénale est guidée par la pression veineuse centrale (PVC) et ce, malgré sa fiabilité limitée en tant que paramètre d'évaluation du volume liquidien intravasculaire, en particulier chez les patients atteints de maladies cardiovasculaires. Les objectifs recommandés lors de la reperfusion du greffon sont une tension artérielle moyenne de 90 mmHg et une PVC de 1214 mmHg. Cette approche pourrait augmenter le risque d'effets indésirables importants dus à une surcharge volémique. Il a été démontré que la thérapie liquidienne périopératoire guidée par des indices dynamiques de réponse au remplissage optimisait le volume intravasculaire et prévenait les complications associées à l'administration liquidienne exagérée lors de chirurgie abdominale majeure. Nous avons émis l'hypothèse qu'une administration liquidienne guidée par la variation de pression différentielle (VPD et delta PP) entraînerait une meilleure optimisation du volume liquidien intravasculaire par rapport à une stratégie guidée par la PVC pendant une chirurgie de transplantation rénale. MéTHODE: Dans cette étude randomisée monocentrique à double insu, 77 patients atteints d'insuffisance rénale terminale, qui ont bénéficié d'une greffe rénale sous anesthésie générale avec analgésie péridurale, ont été randomisés à recevoir une administration liquidienne guidée soit par la PVC (n = 35) ou par la VPD (n = 35) en utilisant des critères hémodynamiques prédéfinis. Le critère d'évaluation principal était le volume total de liquides peropératoires administrés. Les critères secondaires comprenaient les variations hémodynamiques peropératoires, les taux sériques de lactate, la créatininémie, le besoin de dialyse au cours de la première semaine, le taux d'élimination de la créatinine et l'incidence de dysfonctionnement immédiat et retardé du greffon. RéSULTATS: Les résultats ont été analysés pour 70 patients. Quatre-vingts pour cent des patients ont subi une allogreffe de rein provenant d'un donneur vivant apparenté. Les variables opératoires liées aux caractéristiques du donneur, la durée de la chirurgie, le temps d'ischémie froide du greffon et les pertes sanguines étaient comparables dans les deux groupes. Le volume moyen (écart type) de liquides intraveineux administrés en peropératoire était de 1346 (337) mL dans le groupe guidé par VPD vs 1901 (379) mL dans le groupe guidé par PVC (différence de moyennes, 556 mL; intervalle de confiance à 95 %, 385 à 727; P = 0,001). Aucune différence intergroupe significative n'a été observée dans les critères d'évaluation secondaires. CONCLUSION: L'administration liquidienne guidée par la variation de pression différentielle a significativement diminué le volume total de cristalloïdes par rapport à la thérapie liquidienne guidée par la PVC pendant la période peropératoire chez les patients ayant bénéficié d'une greffe de rein. Néanmoins, notre étude ne disposait pas de la puissance suffisante pour détecter les différences dans les critères d'évaluation secondaires.

BACKGROUND: Nitrous oxide has been used during surgical anesthesia for many years. However, information about occupational exposure and related risks due to N2O exposure to the health care personnel in India are still poorly understood. Here, we measured the residual N2O levels during the working time of operation theatre room air in our tertiary care hospital. MATERIAL AND METHODS: The air samples were collected from different anesthesia exposure zones on different days for quantitative analysis of available N2O in the room air in respective areas. Nitrous oxide concentrations in the ambient air were also measured to compare outdoor and indoor levels. OBSERVATIONS AND RESULTS: Nitrous oxide mixing ratios were found to be 65.61 ± 0.05 ppm, 281.63 ± 0.43 ppm, and 165.42 ± 0.42 ppm in elective surgical theatres of the hospital on three different days whereas in emergency operation theatres of the same hospital levels of N2O were 166.75 ± 0.07 ppm, 510.19 ± 0.30 ppm and 2443.92 ± 0.64 ppm during same period. In elective pediatric surgical theatres levels of N2O were found to be 1132.55 ± 0.70 ppm and 362.21 ± 0.13 ppm on two days of reading respectively. Outdoor levels of N2O in contrast found 0.32 ± 0.01 ppm and was lower by a factor of 1000. CONCLUSION: We observed the very high ambient concentration of N2O in the surgical theatre's environment (up to 2443 ppm) and recovery areas (up to 50 ppm). It was 5 to 50 times higher ambient concentration of N2O than REL in OT area and 200-7000 times higher ambient concentration of N2O than outdoor ambient air in all surgical theaters other than CTVS OTs.
RESUMEN
Background Survivors of COVID-19 pneumonia may have residual lung injury and poor physical and mental health even after discharge. We hypothesized that COVID-19 severe acute respiratory distress syndrome (ARDS) patients needing mechanical ventilation may be at a greater risk of deterioration in pulmonary function, mental health, and quality of life (QOL). This study analyses the differences in pulmonary function, mental health, and QOL after recovery, in patients having received non-invasive oxygen therapy versus invasive mechanical ventilation during ICU stay. Methods Patients aged >18 years, who had completed 3 months post ICU discharge, with moderate to severe COVID-19 ARDS, were consecutively enrolled from May 1 to July 31, 2021. Patients were allocated into Group A - having required high flow nasal cannula (HFNC)/non-invasive ventilation (NIV) and Group B - having received invasive mechanical ventilation. Pulmonary function tests, 6-minute walk test (6-MWT), and health-related quality of life were compared. Results Of the 145 eligible patients, 31 were lost to follow-up and 21 died. Seventy-four patients were allocated into Groups A (57 patients) and B (17 patients). In Group A, abnormal forced expiratory volume in first second (FEV1), forced vital capacity (FVC), forced expiratory flow in mid-half of FVC (FEF25-75), and peak expiratory flow rate (PEFR) values were obtained in 27 (47.37%), 43 (75.44%), 11 (19.3%), and 25 (43.86%) patients, and in Group B, in 13 (76.47%), 17 (100%), 1 (5.88%), and 8 (47%) patients, respectively. No patient had abnormal FEV1/FVC. All Group B patients had a restrictive pattern in spirometry as compared to 77% in Group A. Group B had a lower arterial partial pressure of oxygen (PaO2) (p=0.0019), % predicted FVC (p<0.0001), % predicted FEV1 (p=0.001), and 6-MWT distance (p<0.001). The physical component score in the short-form survey 12 questionnaire was higher in group A, p<0.001, whereas the mental component score was comparable. Conclusions Patients requiring invasive mechanical ventilation (MV) have a greater risk of impaired pulmonary function and reduced QOL post-ICU discharge. This warrants a greater need for following these patients for better rehabilitation.
RESUMEN
Rectal foreign bodies are not uncommon and often pose a serious challenge to surgeons. In majority, the objects are inserted by self in children, psychiatric patients and for sexual gratification in adults. Various rectal foreign bodies have been reported. Deodorant aerosol spray can in the rectum has not been reported previously. Danger of aerosol dispenser can is the risk of fire and explosion. Especially during any surgical procedures to remove the foreign body using cautery or any energy devices. We report of a rare foreign body of deodorant aerosol spray can in the rectum in a young male patient, which was removed under general anaesthesia.

Background and objectives Recent randomized controlled trials (RCTs) have indicated potential therapeutic benefits with high-dose dexamethasone (HDD) or tocilizumab (TCZ) plus standard care in moderate to severe coronavirus disease 2019 (COVID-19) with acute respiratory distress syndrome (ARDS). No study has compared these two against each other. We aimed to compare the efficacy and safety of HDD against TCZ in moderate to severe COVID-ARDS. Methods Patients admitted with moderate to severe COVID-19 ARDS with clinical worsening within 48 hours of standard care were randomly assigned to receive either HDD or TCZ plus standard care. The primary outcome was ventilator-free days (VFDs) at 28 days. The main secondary outcomes were 28-day all-cause mortality and the incidence of adverse events. Our initial plan was to perform an interim analysis of the first 42 patients. Results VFDs were significantly lower in the HDD arm (median difference: 28 days; 95% confidence interval (CI): 19.35-36.65; Cohen's d = 1.14;p < 0.001). We stopped the trial at the first interim analysis due to high 28-day mortality in the HDD arm (relative risk (RR) of death: 6.5; p = 0.007; NNT (harm) = 1.91). The incidence of secondary infections was also significantly high in the HDD arm (RR: 5.5; p = 0.015; NNT (harm) = 2.33). Conclusions In our study population, HDD was associated with a very high rate of mortality and adverse events. We would not recommend HDD to mitigate the cytokine storm in moderate to severe COVID-19 ARDS. TCZ appears to be a much better and safer alternative.
RESUMEN
BACKGROUND: The most frequent complication of nasotracheal intubation (NTI) is epistaxis. Epinephrine nasal gauze packing has been used conventionally as a pre-treatment for reducing epistaxis, but it carries a disadvantage of pain and anxiety in patients. However, xylometazoline drops are easier to administer and more convenient for patients. We aimed at comparing the effectiveness of xylometazoline drops and epinephrine merocele packing in reducing bleeding and postoperative complications in our population. METHODS: Our study enrolled 120 patients in a double-blind randomized controlled trial. We randomly allocated ASA1 or 2 adult patients into 2 groups: Group X and Group E. Group X received 0.1% xylometazoline nasal drops, and epinephrine (1:10,000) merocele nasal packing was used in Group E. The primary outcome was the incidence of bleeding during NTI; the severity of bleeding, navigability, bleeding during extubation, and postoperative complications were secondary outcomes. We used IBM SPSS and Minitab software for statistical analysis, and P < 0.05 was considered statistically significant. RESULTS: We analyzed the data of 110 patients: 55 in Group X and 55 in Group E. The two groups did not have different bleeding incidence (56.4% vs 60.0%; P = 0.70); however, the incidence of severe bleeding was less with xylometazoline than with epinephrine (3.63% vs 14.54%; P < 0.05). We also observed less bleeding during extubation (38.2% vs 68.5%; P < 0.05) with xylometazoline. Other secondary outcomes were akin to both groups. CONCLUSION: The incidence of severe and post-extubation bleeding was significantly less with xylometazoline. Hence, it may be an effective alternative for reducing the incidence and severity of epistaxis during NTI.
RESUMEN
COVID-19 pandemic is an emerging, rapidly evolving public health emergency where a nation's health-care system can face a marked surge in demand for intensive care unit (ICU) beds and organ support. In regions with insufficient medical resources, it may further aggravate the existing shortage, limiting an ICU's ability to provide the normal standard of care. It can present ethically or legally demanding questions about how to prioritize the allocation of life-saving medical resources. In developing countries like India, still many hospitals are challenged by competing priorities and remain underprepared. In the wake of COVID-19 pandemic, to guide the intensive care disaster planners in regions with low resources and to ensure ICU readiness, this review shares our experience and strategies for preparing ICU with existing and alternative resources, focusing on space, equipment, and health-care workers' safety and training.
RESUMEN
CONTEXT: Trauma-induced coagulopathy (TIC) is life-threatening in head injury patients, and there is a lack of Indian data on its incidence and outcome. AIMS: In this study, incidence and outcome related to coagulopathy were assessed in patients with moderate-to-severe isolated traumatic brain injury (iTBI). SETTINGS AND DESIGN: A prospective observational study carried out in patients admitted within 24 h of injury. MATERIALS AND METHODS: One hundred patients with moderate-to-severe iTBI were included. Samples for coagulation tests (prothrombin time [PT], PT index [PTI], international normalization ratio [INR], activated partial thromboplastin time, and platelet count) were collected at 5 points of time for 72 h. TIC was diagnosed if any three readings were abnormal during this period. Patients were also followed up posthospital discharge using the Glasgow Outcome Score (GOS) at 1 and 3 months. STATISTICAL ANALYSIS: Data were analyzed using SPSS ver. 21. Logistic regression analysis was employed to determine individual coagulation test as best predictors for mortality. P < 0.05 was considered statistically significant. RESULTS: The incidence of TIC was found to be 62%; it was 63.75% in severe head injury and 55% in moderate head injury patients. Deranged INR at the time of hospital admission (odds ratio [OR] 4.38) and PTI at 24 h (OR 3.913) are highly predictive of mortality. There was no significant difference in GOS score at 1 and 3 months. CONCLUSIONS: The incidence of TIC in our study was 62% among iTBI patients. It contributes to increased mortality at 1 and 3 months. However, the neurological outcome was not different in between the groups.
