Consequence and Prevention of Haemodynamic Stress Response during Laryngoscopy and Endotracheal Intubation with Oral Ivabradine- A Multicentric Randomised Controlled Study
Introduction: Laryngoscopy and intubation cause lots of haemodynamic changes which adversely affects the patient during the perioperative period. Various methods have been applied to reduce stress response in high risk patients. Ivabradine is a unique cardiotonic drug which reduces the heart rate without compromising blood pressure, specially in debilitating and severely ill patients.
Aim: To evaluate role of oral ivabradine in attenuating the haemodynamic stress response to laryngoscopy, intubation and extubation in patients undergoing surgical procedure under General Anaesthesia (GA) and to note the side-effects and its complications, if any.
Materials and Methods: A randomised controlled multicentric study was conducted in 200 American Society of Anaesthesiologists’ (ASA)-I and II patients undergoing various surgery under general anaesthesia. The patients were randomly divided into two groups: group A (Test group, n=100) received 5 mg oral ivabradine one hour before intubation, group B (Control group, n=100) received placebo. The pulse rate, Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) and Mean Arterial Pressure (MAP) were recorded at intubation and 10 minutes postintubation along with at extubation and postintubation period till 10 minutes. Patients were monitored for haemodynamic changes as per the protocol. Statistics analysis was done using Statistical Package of Social Science (SPSS) software version 21.0.
Results: Demographic findings were comparable in both groups. Heart rate (84.36±4.11 versus 114.19±12.4), SBP (120±10.5 versus 150±17.5), DBP (76.08±4.29 versus 113.2±10.6), MAP (91.3±6.7 versus 124.4±12.8) at 10 minutes postintubation decreased more in test group as compared to control group from baseline (p-value <0.005). Similarly, heart rate (84.13±2.06 versus 110.58±8.92), SBP (123.4±10.06 versus 150.8±13.1), DBP (84.08±2.02 versus 107±10.2), MAP (97.8±6.47 versus 122.06±9.7) at 10 minutes postintubation decreased significantly in test group as compared to control group from baseline (p-value <0.005).
Conclusion: Oral ivabradine is a very useful cardiotonic drug which facilitates the fluctuation in heart rate during laryngoscopy and endotracheal intubation
Albiglutide and cardiovascular outcomes in patients with type 2 diabetes and cardiovascular disease (Harmony Outcomes): a double-blind, randomised placebo-controlled trial
Background:
Glucagon-like peptide 1 receptor agonists differ in chemical structure, duration of action, and in their effects on clinical outcomes. The cardiovascular effects of once-weekly albiglutide in type 2 diabetes are unknown. We aimed to determine the safety and efficacy of albiglutide in preventing cardiovascular death, myocardial infarction, or stroke.
Methods:
We did a double-blind, randomised, placebo-controlled trial in 610 sites across 28 countries. We randomly assigned patients aged 40 years and older with type 2 diabetes and cardiovascular disease (at a 1:1 ratio) to groups that either received a subcutaneous injection of albiglutide (30–50 mg, based on glycaemic response and tolerability) or of a matched volume of placebo once a week, in addition to their standard care. Investigators used an interactive voice or web response system to obtain treatment assignment, and patients and all study investigators were masked to their treatment allocation. We hypothesised that albiglutide would be non-inferior to placebo for the primary outcome of the first occurrence of cardiovascular death, myocardial infarction, or stroke, which was assessed in the intention-to-treat population. If non-inferiority was confirmed by an upper limit of the 95% CI for a hazard ratio of less than 1·30, closed testing for superiority was prespecified. This study is registered with ClinicalTrials.gov, number NCT02465515.
Findings:
Patients were screened between July 1, 2015, and Nov 24, 2016. 10 793 patients were screened and 9463 participants were enrolled and randomly assigned to groups: 4731 patients were assigned to receive albiglutide and 4732 patients to receive placebo. On Nov 8, 2017, it was determined that 611 primary endpoints and a median follow-up of at least 1·5 years had accrued, and participants returned for a final visit and discontinuation from study treatment; the last patient visit was on March 12, 2018. These 9463 patients, the intention-to-treat population, were evaluated for a median duration of 1·6 years and were assessed for the primary outcome. The primary composite outcome occurred in 338 (7%) of 4731 patients at an incidence rate of 4·6 events per 100 person-years in the albiglutide group and in 428 (9%) of 4732 patients at an incidence rate of 5·9 events per 100 person-years in the placebo group (hazard ratio 0·78, 95% CI 0·68–0·90), which indicated that albiglutide was superior to placebo (p<0·0001 for non-inferiority; p=0·0006 for superiority). The incidence of acute pancreatitis (ten patients in the albiglutide group and seven patients in the placebo group), pancreatic cancer (six patients in the albiglutide group and five patients in the placebo group), medullary thyroid carcinoma (zero patients in both groups), and other serious adverse events did not differ between the two groups. There were three (<1%) deaths in the placebo group that were assessed by investigators, who were masked to study drug assignment, to be treatment-related and two (<1%) deaths in the albiglutide group.
Interpretation:
In patients with type 2 diabetes and cardiovascular disease, albiglutide was superior to placebo with respect to major adverse cardiovascular events. Evidence-based glucagon-like peptide 1 receptor agonists should therefore be considered as part of a comprehensive strategy to reduce the risk of cardiovascular events in patients with type 2 diabetes.

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries
Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Hepatitis B Vaccination Coverage among Healthcare Workers and Evaluation of Immune Response by Estimating Anti-HBs Antibody Titers over Time at a Tertiary Care Hospital: A Cross-sectional Study
Introduction: Healthcare Workers (HCWs) are at a high-risk of
acquiring Hepatitis B Virus (HBV) infection. However, this risk
can be prevented through Hepatitis B vaccination. In some
institutes, HCWs have a lower percentage of HBV vaccination,
leading to a higher risk of HBV transmission. Therefore, the
coverage of vaccination is an important point, along with the
evaluation of protective immune status.
Aim: To assess the vaccination coverage and evaluate the
immune response post-vaccination through Anti-Hepatitis B
surface Antibodies (Anti-HBs) titre.
Materials and Methods: This cross-sectional study was
conducted at Government Medical College, Pali, Rajasthan,
India, over a period of one year from April 2021 to March 2022,
following approval from the Institutional Ethics Committee (IEC).
A total of 455 HCWs below 60 years of age were included in
the study, and their demographic details such as age, gender,
occupation, needle stick injury, blood exposure to mucous
membranes and breached skin, hepatitis B vaccination status,
and time duration since vaccination were noted. Additionally,
their Anti-HBs titer was examined. The participants were
initially classified into three groups: completely vaccinated,
partially vaccinated, and non vaccinated. Among those who
were vaccinated, they were further divided into two groups:
vaccination ≤5 years (Group A) and >5 years (Group B).
Furthermore, those who received a booster dose were divided
into Group I (≤1 year) and Group II (>1 year). Blood samples
were collected to assess the anti-HBs levels quantitatively in
the sera using Enzyme Linked Immuno Sorbent Assay (ELISA).
The data was entered into Microsoft Excel and later imported
into Statistical Package for Social Sciences (SPSS) version 22.0
for statistical analysis.
Results: Participants had a mean age of 29.65±9.603 years.
Among them, 43 (30.1%) were doctors, and 37 (25.9%) were
medical students who were found to be completely vaccinated.
On the other hand, among other HCWs, 15 (10.5%) were
nurses, 16 (11.2%) were nursing students, and 32 (22.4%)
were lab technicians who were vaccinated. None of the
support staff were vaccinated (p-value=0.0001). A total of 143
participants were completely vaccinated, and 97.9% (n=140)
had protective immunity to Hepatitis B. The anti-Hbs titre was
567.32±434.494 in group A and 265.74± 211.80 in group B
(p-value=0.0001). Similarly, it was 688.34±424.617 in group I
and 221.14±141.221 in group II (p-value <0.0001).The anti-Hbs
titre did not significantly increase among the partially vaccinated
participants (n=162). It was found to be 25.47±27.595 in group
A and 14.60±19.939 in group B (p-value=0.004). There was no
significant difference in the results between males and females
(p-value=0.961).
Conclusion: The coverage of complete vaccination among
HCWs was significantly low, which is crucial for obtaining a
protective Anti-Hbs titre. Incomplete vaccination does not
result in a sufficient level of anti-Hbs titre, and there may
be a significant decline in the immune response over time
(p-value<0.05). Therefore, it is essential to estimate the titre after
1-2 months of complete vaccination to ensure that individuals
are fully protected against Hepatitis B
Comparative Analysis of Local Anesthetic Techniques for Pain Management in Pediatric Dental Procedures: A Randomized Clinical Trial
Objective: The present study aims to conduct a comparative analysis of different local anesthetic techniques for pain management in pediatric dental procedures. Goal is to evaluate and compare the efficacy and safety of various local anesthetic methods to identify the most effective approach in reducing pain and discomfort during dental treatments in children. Methods: A prospective, randomized clinical trial was conducted with 60 pediatric patients (aged 3 to 10 years) undergoing dental procedures in a single dental clinic. The participants were randomly assigned into three groups: Group A received conventional infiltration anesthesia (lidocaine 2% with epinephrine 1:100,000), Group B received topical anesthesia followed by the same infiltration anesthesia, and Group C received intraosseous anesthesia using articaine 4% with epinephrine 1:100,000. The patients' demographic data, treatment details, and pre-procedure anxiety levels were recorded. Results: The study demonstrated that all three local anesthetic techniques effectively managed pain during pediatric dental procedures. However, Group C, which received intraosseous anesthesia, showed significantly lower pain scores (mean ± standard deviation) compared to Group A and Group B: 1.5 ± 0.6, 2.3 ± 0.8, and 2.1 ± 0.7, respectively (P < 0.05). Additionally, Group C exhibited a shorter onset of anesthesia compared to Group A and Group B, with mean onset times of 1.8 ± 0.4, 3.2 ± 0.6, and 2.9 ± 0.5 minutes, respectively (P < 0.001). No significant differences in adverse events or post-procedure complications among the groups. Conclusion: Intraosseous anesthesia (articaine 4% with epinephrine 1:100,000) was found most effective local anesthetic technique for pain management during pediatric dental procedures
AutoFlow® (volume-guaranteed mode) versus volume-controlled ventilation for the laparoscopic surgery with BlockBuster supraglottic airway: A randomized controlled trial
Background and Aims: Supraglottic airway devices used in laparoscopic surgeries must be efficient to counter the increased peak airway pressure (PAWP) and airway leakage that can occur in laparoscopic surgeries. Hence, the implication of AutoFlow in ventilator strategy is propounded nowadays that facilitates low PAWP and high dynamic compliance to achieve targeted tidal volume and end-tidal carbon dioxide (ETCO2). BlockBuster™ Laryngeal mask furnishing minimum airway leak. The primary objective was to compare PAWP using the two modes of ventilation through the BlockBuster LMA after intubation, pneumoperitoneum, and Trendelenburg position. The secondary objective was to observe hemodynamic vitals.
Methodology: In this single-center randomized controlled trial, we recruited 80 American Society of Anesthesiologists grade I and II adult patients undergoing elective laparoscopic surgeries. They were randomized by computer-generated method into two groups: volume-controlled AutoFlow® (VCAF) and volume-controlled (VC) group. Ventilation settings for both groups set to tidal volume 5–6 ml/kg of predicted body weight, positive end-expiratory pressure 5 cm H2O, I: E ratio 1:2, and respiratory rate 12–16/min to maintain targeted ETCO2 of 30–35 cm H2O. Intraabdominal pressure was set to 14 mmHg during pneumoperitoneum and 15° Trendelenburg position.
Results: Mann–Whitney U-test for continuous variables and t-test for categorical variables. Data were presented as median (interquartile range). P <0.05 was considered statistically significant. During laparoscopic surgeries with BlockBuster™ PAWP at pneumoperitoneum was (20 cm H2O vs. 27 cm H2O) and Trendelenburg position (19 cm H2O vs. 27 cm H2O) was significant lower with VCAF (AutoFlow® ventilation) than with VC (P < 0.05).
Conclusion: PAWP is significantly low in AutoFlow mode as compared to volume control mode with BlockBuster LMA. In addition, LMA BlockBuster provides good sealing pressure
