Effect of COVID-19 vaccination status on outcome of adult patients admitted at a tertiary care centre in India.

COVID-19 vaccination was initially started in India on 16th January 2021 after approval from national authorities. This study was carried out to assess the effect of vaccination status on the severity and clinical outcome among patients infected with COVID-19. The study included all adult COVID-19 patients admitted to our hospital from 1st April to 30th June 2021. A total of 819 patients were enrolled in the study out of which only 183 (22.3%) were vaccinated. The study documented a statistically significant reduction in the severity of illness among the vaccinated (single/double dose) (33% severe COVID-19) against the unvaccinated (43% severe COVID-19) groups; along with a reduction in mortality. On univariate and multivariate analysis, age, severity of illness and lack of COVID-19 vaccination status were associated with a statistically significant increased mortality. To conclude, this study demonstrates the role of vaccination in decreasing the severity and mortality of COVID-19 infection.

Depression, Anxiety, Stress, and Insomnia amongst COVID Warriors across Several Hospitals after Second Wave: Have We Acclimatized? A Cross-sectional Survey.

Background: Coronavirus disease-2019 (COVID-19) pandemic has been a cause of significant mental health disturbances in medical health personnel. However, 18 months into the pandemic, healthcare workers (HCWs) have become accustomed to the heightened stress and anxiety that comes with caring for COVID patients. Through this study, we aim to measure depression, anxiety, stress, and insomnia in doctors with the help of validated scales. Materials and methods: This was a cross-sectional study with an online survey design conducted among doctors from major hospitals in New Delhi. The questionnaire included participant demographics, including designation, specialty, marital status, and living arrangements. This was followed by questions from the validated depression, anxiety, stress scale (DASS-21), and insomnia severity index (ISI). Depression, anxiety, stress, and insomnia scores were calculated for each participant, and the data were analyzed statistically. Results: The mean scores of the whole study population showed no depression, moderate anxiety, mild stress, and subthreshold insomnia. Female doctors exhibited more psychological issues (mild depression and stress, moderate anxiety, but only subthreshold insomnia) as compared to males (mild anxiety, but no depression, stress, and insomnia). Junior doctors also had higher depression, anxiety, and stress scores than senior doctors. Similarly, single doctors, those living alone, and those not having kids had higher DASS and insomnia scores. Discussion: HCWs have been under tremendous mental stress during this pandemic which is influenced by multiple factors. Female sex, junior doctors, working on the frontline, not being in a relationship, and living alone may be some of the factors recognized in our study and corroborated by many authors, which may increase the chances of depression, anxiety, and stress in them. HCWs need regular counseling, time off for rejuvenation, and social support to overcome this hurdle. How to cite this article: Kohli S, Diwan S, Kumar A, Kohli S, Aggarwal S, Sood A, et al.

Mortality among adult hospitalized patients during the first wave and second wave of COVID-19 pandemic at a tertiary care center in India.

The similarities and differences between the mortality patterns of the two waves in India remain largely unknown. This was a retrospective study of medical records conducted in the COVID data center of our hospital This study analyzed data of patients who died in the month of August, 2020 to October 2020 (one month before and after the peak of first wave i.e., 16th September, 2020) and April 2021 to June 2021 (one month before and after the peak of second wave i.e., 6th May, 2021), corresponding to an equal part of the pandemic during first (2020) and second (2021) wave. Out of 1893 patients in the study, 764 patients were admitted during the first wave and 1129 patients during the second wave of pandemic. In total, 420 patients died during the entire study period. Of those, 147 (35%) deaths occurred during the first wave and 273 (65%) during the second wave, reflecting a case fatality rate (CFR) of 19.2% during the first wave and a CFR of 24.18%. There were no significant differences in the age group, gender, presenting complaints, duration of stay and comorbidities. However, the deceased COVID-19 patients had an increase in case fatality rate, average duration of symptoms from onset to hospital admission (DOSHA) and a major shift from MODS to ARDS being the cause of death during the second wave of pandemic. This study demonstrates increased CFR, average DOSHA and a paradigm shift to ARDS as cause of mortality during the second peak of the pandemic. It is necessary to remain vigilant of newer COVID-19 variants of concern, follow COVID-19 appropriate behaviors and keep emphasizing on care of high-risk groups including patients with comorbidities and elderly population to prevent mortality.

Neurological Manifestations of COVID-19: A Series of Seven Cases.

Identification of neurological manifestations associated with SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2) in patients with no or mild pulmonary infection proves to be a challenge. The incidence of neurological associations of COVID-19 may be small as compared with respiratory disease; however, in the present scenario with an increasing number of cases each day, the overall incidence of patients with neurological manifestations and their health-related socioeconomic impact might be large. Hence it is important to report such cases so that healthcare providers and concerned authorities are aware of and may prepare for the growing burden. The literature on primary neurological manifestations of COVID-19 is limited, and hence our case series is relevant in the current scenario. The most commonly reported neurological complications are cerebrovascular accidents, encephalopathy, encephalitis, meningitis, and Guillain-Barr é syndrome (GBS). We present a series of seven cases with various neurological presentations and possible complications from this novel virus infection.

Permissive hypotension in traumatic brain injury with blunt aortic injury: How low can we go?

With an ever-increasing incidence of high impact collisions, polytrauma is becoming increasingly common. Patients with traumatic brain injury (TBI) may require urgent surgical intervention along with maintenance of an adequate mean arterial pressure (MAP) to maintain cerebral perfusion. On the other hand, patients who sustain blunt aortic injuries (BAI) have a high mortality rate, many of them succumbing to their injury at the site of trauma. Surgery has been the mainstay of the management strategy for the remaining survivors. However, in recent years, the paradigm has shifted from early operative management to conservative treatment with aggressive blood pressure and heart rate control, serial imaging, and close clinical monitoring. When TBI and BAI coexist in a patient, it becomes crucial to maintain the MAP within a narrow range to prevent secondary insult to the brain as well as to prevent aortic rupture. We present the management of a case of TBI with traumatic aortic pseudoaneurysm, which required stringent monitoring and maintenance of hemodynamics during decompressive craniectomy.

Comparison of ropivacaine, bupivacaine, and lignocaine in femoral nerve block to position fracture femur patients for central neuraxial blockade in Indian population.

BACKGROUND: Patients with a fractured femur experience intense pain during positioning for neuraxial block for definitive surgery. Femoral nerve block (FNB) is therefore often given prior to positioning for analgesia. In our study, we compare the onset and quality of block of 0.25% bupivacaine, 0.5% ropivacaine, and 1.5% lignocaine for FNB in fracture femur patients. METHODS: Seventy-five adult femur fracture patients were equally and randomly divided into three groups to receive 15 ml of either 0.25% bupivacaine (group B), 0.5% ropivacaine (group R), or 1.5% lignocaine (group L) for FNB prior to positioning for neuraxial blockade. Onset and quality of block were assessed, as well as improvement in visual analog scale (VAS) score, ease of positioning, and patient satisfaction. RESULTS: Percentage decrease in VAS was found to be highest in group R (82.8%) followed by groups L and B. Time to achieve a VAS of less than 4 was found to be 26.2±2.4 minutes in group B, 8.5±1.9 minutes in group R, and 4.1±0.7 minutes in group L (P<0.001). In group B, 12 patients required additional fentanyl to achieve a VAS <4. Patient positioning was reported to be satisfactory in all patients in group R and L, while in B it was satisfactory in 13 (52%) patients only. Patient acceptance of FNB was 100% in group R and L, but only 64% in group B. CONCLUSIONS: Based on our findings, 0.5% ropivacaine is a favorable choice for FNB due to early onset, ability to yield a good quality block, and good safety profile.

Brachial plexus block: Comparison of two different doses of clonidine added to bupivacaine.

BACKGROUND: The role of clonidine as an adjuvant to local anesthetic agents in brachial plexus block (BPB) has been extensively studied. However, till date there has been no consensus about the ideal dose of clonidine for this purpose. This study was carried out to evaluate two doses of clonidine-1 and 2 g/kg, added to 0.5% bupivacaine, with regard to onset and duration of sensorimotor blockade, hemodynamic effects, postoperative analgesia, and adverse effects. MATERIALS AND METHODS: Sixty adult patients undergoing upper limb surgeries were randomly allocated into two groups. Thirty patients received 1 g/kg clonidine (group I) and the rest received 2 g/kg clonidine (group II) added to 30 mL of 0.5% bupivacaine through nerve stimulator-guided supraclavicular BPB. The onset and duration of sensorimotor blockade, hemodynamic variables, duration of analgesia, level of sedation, and adverse effects was assessed. RESULTS: The onset of sensorimotor block was earlier in group II (9.9 ± 4.1 min for sensory block and 13.2 ± 6.7 min for motor block) than in group I (15.9 ± 6.8 min for sensory block and 18.5 ± 7.8 min for motor block). The duration of analgesia was also prolonged in patients receiving the higher dose (21.0 ± 2.96 h vs. 14.9 ± 3.0 h). Although hemodynamics remained comparable in both the groups, incidence of hypotension and bradycardia was higher in group II as compared to group I. The sedation was clinically and statistically more in group II patients (43% vs. 17%). CONCLUSION: Higher dose of clonidine in BPB hastens the onset, prolongs the duration of sensorimotor blockade and postoperative analgesia without significant hemodynamic alterations. It also causes more sedation, which although ensures patient comfort in most cases, but might be undesirable in certain situations.

A Prospective Study of Specialized Coagulation Parameters in Admitted COVID-19 Patients and Their Correlation With Acute Respiratory Distress Syndrome and Outcome.

Background Acute respiratory distress syndrome (ARDS) is a frequent complication of COVID-19 and is associated with a component of thrombo-inflammation and cytokine storm. COVID-19 also affects the hemostatic system causing multiple coagulation abnormalities that is a cause of concern and needs to be addressed.  Objective We aimed to assess coagulation parameters of COVID-19 patients and identify whether they could be used as potential prognostic biomarkers to predict ARDS and immediate outcomes. Methods This was a prospective study done on 68 patients at four serial time points. Patients between 18-85 years admitted to the hospital as in-patients and ICU with a confirmed diagnosis of COVID-19 by RT-PCR were included. Exclusion criteria included pregnancy, patients below and above the mentioned age, previously known coagulopathy, systemic anticoagulants or anti-platelet therapy or vitamin K antagonists and moribund patients. Patients were divided into three categories based on SOFA score at admission, presence (group 1) or absence (group 2) of ARDS and outcome (dead or alive). Routine and specialized coagulation tests were performed on patients' platelet-poor plasma at the time of study inclusion (day 0), days 3, 7 and at discharge on STAR Max®3 (Diagnostica Stago France) automated coagulation analyzer and included prothrombin time (PT), international normalized ratio (INR) (STA® -NeoPTimal), activated partial thromboplastin time (APTT) (STA® -Cephascreen), fibrinogen (STA® Liquid Fib), D-dimer (STA® LiatestD- Dimer), Protein C (STA Stachrom® Protein C), Protein S (STA® Latest Free Protein S) and Antithrombin (STA® Chrom ATIII). ELISA did testing for tissue plasminogen activator (Asserachrom® tPA) as per the manufacturer's protocol. Results Sixty-eight patients, including 43 (63%) males and 25 (37%) females, with a median age of 48 years (IQR 20-85), were recruited in this study. The incidence of ARDS was 34%, with a mortality of 13%. History of contact with a COVID-19 case was present in 71% (48/68) of the patients. Fever was the most common presenting symptom in 84% (57/68) of the patients. The most common comorbidities were hypertension and diabetes mellitus (DM) in 22% (15/68) and 21% (14/68) of the patients. DM (p=0.07) and chronic obstructive pulmonary disease (COPD) (p=0.03) were significantly associated with ARDS. DM (p=0.02), hypertension (p=0.01), and COPD (p=0.02) were also significantly associated with mortality. APTT was markedly prolonged among non-survivors at day 0 (D0) and D7 (p=0.03, p=0.02). D-Dimer was elevated in 38/68 (56%) patients at D0. D-Dimer levels were significantly higher in non-survivors (p<0.001), in ARDS patients (p=0.001) and patients with higher SOFA scores (p=0.001). ROC curve showed that D-dimer cut-off > 2.13 (AUC of 0.86) and >0.85 (AUC of 0.74) predicts mortality and ARDS, respectively. Among the natural anticoagulants, protein C was significantly associated with a high SOFA score at D0 and D3 (p=0.04).  Conclusion Diabetes mellitus, hypertension and COPD were associated with poor outcomes. D-dimer levels must be monitored in COVID patients due to their association with ARDS and mortality. We observed that the levels of natural anticoagulants fell during the illness, making them prone to coagulopathies; however, none were seen in this study. Elevated tPA levels were also found in our patients; fibrinolytic therapy may benefit COVID-19 patients suffering from ARDS.

Anatomic variation of subclavian artery visualized on ultrasound-guided supraclavicular brachial plexus block.

Use of ultrasonography for performance of nerve and plexus blocks has made the process simpler and safer. However, at times, variant anatomy of the visualized structures can lead to failure of blocks or complications such as intravascular injections. This is especially true in case of novice operators. We report a case of a variant branch of subclavian artery, possibly the dorsal scapular artery passing through the brachial plexus nerve bundles in the supraclavicular area. Since this variation in anatomy was visualized in the scout scan prior to the performance of the block, it was possible to avoid any accidental puncture. Hence, a thorough knowledge of the ultrasound anatomy is important in order to identify various aberrations and variations. It is also prudent to perform a preliminary scan, prior to performance of the block to localize the target area and avoid any inadvertent complications.

Arthrogryposis multiplex congenita: airway concerns in an emergency situation.

Difficult airway is always of special concern to anesthesiologists, but in a trauma setting where having a secured airway is most important, the incidence of difficult airway increases manifold. We report a "cannot ventilate cannot intubate" situation in a trauma patient who was later diagnosed to have arthrogryposis multiplex congenita, a syndrome known to affect the airway, and in whom all measures of securing a nonsurgical airway failed.

Topical airway anesthesia for awake fiberoptic intubation: Comparison between airway nerve blocks and nebulized lignocaine by ultrasonic nebulizer.

OVERVIEW: Awake fiberoptic bronchoscope (FOB) guided intubation is the gold standard of airway management in patients with cervical spine injury. It is essential to sufficiently anesthetize the upper airway before the performance of awake FOB guided intubation in order to ensure patient comfort and cooperation. This randomized controlled study was performed to compare two methods of airway anesthesia, namely ultrasonic nebulization of local anesthetic and performance of airway blocks. MATERIALS AND METHODS: A total of 50 adult patients with cervical spine injury were randomly allocated into two groups. Group L received airway anesthesia through ultrasonic nebulization of 10 ml of 4% lignocaine and Group NB received airway blocks (bilateral superior laryngeal and transtracheal recurrent laryngeal) each with 2 ml of 2% lignocaine and viscous lignocaine gargles. FOB guided orotracheal intubation was then performed. Hemodynamic variables at baseline and during the procedure, patient recall, vocal cord visibility, ease of intubation, coughing/gagging episodes, and signs of lignocaine toxicity were noted. RESULTS: The observations did not reveal any significant differences in demographics or hemodynamic parameters at any time during the study. However, the time taken for intubation was significantly lower in Group NB as compared with the Group L. Group L had an increased number of coughing/gagging episodes as compared with Group NB. Vocal cord visibility and ease of intubation were better in patients who received airway blocks and hence the amount of supplemental lignocaine used was less in this group. Overall patient comfort was better in Group NB with fewer incidences of unpleasant recalls as compared with Group L. CONCLUSION: Upper airway blocks provide better quality of anesthesia than lignocaine nebulization as assessed by patient recall of procedure, coughing/gagging episodes, ease of intubation, vocal cord visibility, and time taken to intubate.

Pneumothorax during laparoscopic repair of giant paraesophageal hernia.

Giant paraesophageal hernia is an uncommon morbid disorder which may present a risk of catastrophic complications and should be repaired electively as soon as possible. Laparoscopic fundoplication is the mainstay of surgical management of this disorder due to several advantages such as lower post-operative morbidity and pain. We report a case of a 70-year-old patient with a giant paraesophageal hernia, who developed subcutaneous emphysema with pneumothorax during laparoscopic fundoplication. Early diagnosis was possible by close clinical evaluation and simultaneous monitoring of end-tidal carbon dioxide levels and airway pressures. Although positive end-expiratory pressure application is an effective way of managing pneumothorax secondary to the passage of gas into the interpleural space, insertion of an intercostal drain may be used in an emergent situation.
