Background and Aims: When the world was frantically searching for a drug effective against the coronavirus disease (COVID)-19, remdesivir, a broad-spectrum anti-viral medication, became a part of the COVID treatment. We planned a study to evaluate improvement in clinical outcomes with remdesivir treatment for five days. Methods: Participants more than 40-years old and with moderate to severe COVID-19 but not on mechanical ventilation were randomly assigned into two groups-remdesivir group (34 cases) to receive the study drug intravenous (IV) remdesivir for five days plus the standard care (SC) and non-remdesivir group (36 cases) to receive the SC but not to receive the study drug. Follow-up was continued for 12 days after the beginning of treatment or until discharge/death. Patient's clinical status was assessed by laboratory investigations and physical examination (from day 1 to day 12 on a 4-point ordinal scale and from day 12 to 24 on a 6-point ordinal scale). Oxygen support requirements and adverse events were recorded. The data were entered and analysed using Statistical Package for the Social Sciences (SPSS) version 22.0. Results: High-flow oxygen support and non-invasive ventilation was required at baseline by lesser patients in the remdesivir group. In the end, both groups had similar outcomes after adjustment for baseline clinical status. There was no statistical difference in mortality between the two groups (p = 0.749). Patients in both groups had an equal time to recovery. There was no difference in the occurrence of adverse effects of remdesivir between the two groups. Conclusion: Remdesivir therapy for five days did not produce improvement in clinical outcomes in moderate to severe COVID-19 cases.

Background and Aims:Laryngoscopy and intubation cause sympathetic stimulation and arousal reactions. We evaluated the role of dexmedetomidine and magnesium sulphate on pressor responses to laryngoscopy and intubation as compared to placebo, when depth of anaesthesia was maintained at a constant bispectral index (BIS) range 40-50 (±5).Methods:One hundred and twenty patients were randomised to receive either dexmedetomidine 1 μg/kg (Group DS), magnesium sulphate 30 mg/kg diluted in 100 ml saline (Group MS) or 100 ml normal saline (Group NS) 15 min before induction of anaesthesia in a double blind manner. After achieving BIS 40–50 (±5), laryngoscopy and intubation were performed. Heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded pre-drug, after drug, at intubation, at intervals of 1 min till 5 min, then every 2 min till 10 min and every 10 min for 30 min. Statistical analysis was done using Chi-square test and one way analysis of variance.Results:SBP, DBP and HR fell in the DS and MS groups. No significant changes in BP were seen in the NS group at induction and after intubation. HR rose in the NS group (P < 0.001) at induction from 86.35 ± 9.05 to 95.35 ± 11.60 at 2 min. Patients in DS and MS groups had significantly lower HR, SBP and DBP at laryngoscopy and intubation.Conclusion:At BIS levels 40-50 (±5) there was no pressor response to intubation in the NS Group. Dexmedetomidine and magnesium sulphate significantly reduced the heart rate and blood pressure from baseline.

Aim There are limited data comparing levobupivacaine, ropivacaine, and bupivacaine in paediatric patients. So, this study was performed to evaluate the caudal effectiveness of all the three drugs in paediatric patients undergoing infraumbilical surgeries and associated complications with these drugs. Material and Methods 90 patients of ASA grade I and II posted for elective infraumbilical surgeries were randomly divided into three groups of 30 each. A standardized anaesthetic protocol was used. Patients received 0.25% levobupivacaine in group 1, 0.25% ropivacaine in group 2, and 0.25% bupivacaine in group 3. The effectiveness of block was assessed using caudal effectiveness score. Postoperative pain relief was assessed with modified Hannallah pain score. Haemodynamic parameter monitoring was done. The duration of analgesia and associated complications were studied. Statistical analysis was done using the chi-square test for nonparametric data. Parametric data were analysed using ANOVA for intergroup comparison and Tukey's HSD for intragroup comparison. Results Demographic data were comparable. Haemodynamic parameters remained within normal range. Mean caudal effectiveness score in all the three groups was statistically insignificant (p > 0.05). The duration of analgesia provided by bupivacaine (145.31 ± 26.17 min) was longer than levobupivacaine (126.15 ± 15.15 min) and ropivacaine (114.68 ± 11.32 min) (p < 0.01). Mean postoperative pain scores were lower in group 3 as compared to group 1 and group 2. Conclusion We conclude that levobupivacaine and ropivacaine provide similar intraoperative quality with minimal haemodynamic variability and shorter duration of postoperative analgesia without any significant complications when compared with racemic bupivacaine. This trial is registered with CTRI/2018/03/012402.

Background:Effective pain relief therapy after caesarean section is essential for the parturient's comfort and early ambulation. Paracetamol has an excellent safety profile when compared to opioids.Aim:To assess and evaluate the effect of oral, rectal, and intravenous infusion of paracetamol for post-operative analgesia in women undergoing caesarean section under spinal anaesthesia.Settings and Design:We conducted a prospective, randomized controlled study (18-35 years of age) of the ASA- I and II parturient scheduled for lower segment caesarean section were included.Methods and Materials:They were randomly allocated to 3 groups of 50 each. Group A received oral paracetamol tablet 650mg (1 tablet) 20min before shifting to operation room, group B received rectal paracetamol suppository 35-45 mg/kg immediately after spinal anaesthesia and group C received i.v. paracetamol infusion of 10-15mg/kg over 15min duration 20min before finishing the operation. Duration of analgesia was evaluated as primary outcome and other parameters as secondary outcome.Statistical Tests:All statistical analyses were performed using the SPSS statistical package 17.0 version. Results were analyzed using Chi Square test for non-parametric data and ANOVA for parametric data. P value of less than 0.05 was considered significant and less than 0.001 as highly significant.Results:Duration of analgesia was significantly longer in group B as compared to group A and C. The requirement of supplemental rescue analgesia was also lower in group B compared to group A and C. No significant haemodynamic derangements and adverse effects were noted among all the three groups.Conclusion:Paracetamol when given rectally improves the quality and duration of postoperative analgesia to a greater extent as compared to oral and intravenous route of paracetamol without any side effects.
