Comparison of BlockBuster laryngeal mask with Air-Q intubating laryngeal airway as a conduit for fiber-optic guided intubation in children: A prospective randomized controlled study.

BACKGROUND: The pediatric sizes of BlockBuster supraglottic airway (SGA) have been introduced recently. Its efficacy as a conduit for endotracheal intubation in children has not been assessed. Newer devices are often compared with Air-Q SGA to assess their intubating capability. AIMS: The primary objective was to compare the time taken for fiber-optic-guided intubation through the BlockBuster and the Air-Q SGAs. METHODS: Sixty children aged 6 months to 12 years with normal airways were randomized into two groups: Air-Q SGA (Group A) and Blockbuster SGA (Group B). After administration of general anesthesia, an appropriately sized SGA was inserted. The time taken for fiber-optic-guided intubation through the SGA, success, ease, and time for SGA insertion and removal were noted. The glottic view was graded by fiber-optic bronchoscopy. RESULTS: Demographic parameters were comparable. The time to intubate with the BlockBuster 62.40 ± 17.2 s was comparable to the Air-Q 60.8 ± 18.5 s (mean difference 1.6 s, 95% CI -7.65 to10.85; p = .73). The average time for SGA insertion in BlockBuster and Air-Q was 14.57 ± 3.2 s and 16.67 ± 5.39 s, respectively (mean difference -2.1, 95% CI -4.39 to 0.19 s; p = .07). The first-attempt intubation success and overall intubation success rates were comparable in both groups, 96.7% and 100%, respectively. In Group B, 25/3/1/1/0 cases had a glottic view grade of 1/2/3/4/5, respectively. In Group A, 23/3/2/2/0 cases had grade of 1/2/3/4/5 glottic views respectively. The average time to SGA removal was comparable between the BlockBuster (20.17 ± 5.8 s) and the Air-Q (22.5 ± 12.8 s) groups (mean difference -2.3 s, 95% CI -7.5 to 2.82 s; p = .37). None of the children had any perioperative complications. CONCLUSION: BlockBuster SGA may be a useful alternative to Air-Q for SGA-assisted, fiber-optic-guided tracheal intubation in children.

Faculty development programmes in simulation-based teaching: An exploration of current practices.

Background and Aims: Simulation-based teaching (SBT) has become integral to healthcare education, offering a dynamic and immersive learning experience for bridging theoretical knowledge with real-world clinical practice. Faculty members play a crucial role in shaping the effectiveness of simulation-based education, necessitating the implementation of comprehensive faculty development programmes. This scoping review explores existing literature on training programmes for simulation-based teaching, focusing on strategies employed and the overall impact on educators and the quality of simulation-based education. Methods: The scoping review comprised five sequential steps: identifying the research question; identifying relevant studies; study selection; charting the data; and collating, summarising, and reporting the results. The research questions focused on existing practices and approaches in faculty development for simulation-based teaching, challenges or barriers reported, and the effectiveness of utilised methods and strategies. Results: A systematic search of databases yielded 13 studies meeting inclusion criteria out of 1570 initially screened papers. These studies provided insights into various aspects of faculty development programmes, including their nature, duration, and participant profiles. Despite the diversity in approaches, detailed, specialty-specific programmes were scarce, especially in anaesthesiology. Challenges, while implicit, lacked explicit exploration. Most studies reported positive outcomes, emphasising achievement of learning objectives, appreciable course content, and relevance to teaching practices. Conclusion: This scoping review describes the existing literature regarding the faculty training or development programmes related to SBT. The programmes target various health professionals and have a wide range of durations. The need for such a programme targeting anaesthesiologists is emphasised.

A case of antenatally undiagnosed laryngeal atresia with tracheo-esophageal fistula with airway obstruction at birth and its management.

Laryngeal atresia is a rare congenital anomaly that is usually diagnosed by antenatal ultrasound, however, if undiagnosed presents with desaturation after birth. A term neonate presented with airway obstruction after birth with multiple failed attempts at intubation and was rescued by proseal laryngeal mask airway (LMA). An esophagoscopy using an Ambuscope utilizing a modified connector assembly revealed an opening on the anterior wall of the esophagus with no esophageal atresia, leading to a diagnosis of H-type tracheo-esophageal fistula (TEF) with laryngeal atresia. The ability to ventilate the neonate via LMA with an absent glottic opening raised the possibility of TEF.

Comparison of Ambu AuraGain and BlockBuster laryngeal mask for controlled ventilation in children undergoing minor surgical procedures under general anesthesia: A prospective randomized controlled study.

BACKGROUND: Ambu AuraGain has proven to be better compared with other supraglottic airway devices in terms of higher first-attempt insertion success rate, time and ease of insertion, high oropharyngeal leak pressure, and fewer complications in children. The performance of the BlockBuster laryngeal mask has not been evaluated in children. AIMS: The primary objective of this study was to compare the oropharyngeal leak pressure of the BlockBuster laryngeal mask with those of the Ambu AuraGain during controlled ventilation in children. METHODS: Fifty children aged 6 months to 12 years with normal airways were randomized into group A (Ambu AuraGain) and group B (BlockBuster laryngeal mask). After administration of general anesthesia, an appropriate size supraglottic airway (size 1.5/2.0/2.5) was inserted according to the groups. Oropharyngeal leak pressure, success and ease of supraglottic airway insertion, gastric tube insertion, and ventilatory parameters were noted. The glottic view was graded by fiberoptic bronchoscopy. RESULTS: Demographic parameters were comparable. The mean oropharyngeal leak pressure in the BlockBuster group (24.72 ± 6.81 cm H2 O) was significantly higher than Ambu AuraGain group (17.20 ± 4.28 cm H2 O) by 7.52 cm H2 O (95% CI 4.27 to 10.76; p = 0.001). The mean time for supraglottic airway insertion in the BlockBuster and Ambu AuraGain group was 12.04 ± 2.55 s and 13.64 ± 2.76 s, respectively (mean difference- 1.6 s, 95% CI 0.09-3.12; p = 0.04). Ventilatory parameters, first-attempt supraglottic airway insertion success rate, and ease of gastric tube insertion were comparable between the groups. The BlockBuster group showed easy supraglottic airway insertion compared with the Ambu AuraGain group. The BlockBuster group had better glottic views with only the larynx seen in 23 out of 25 children compared to the Ambu AuraGain with only the larynx seen in 19 out of 25 children. No complication was noted in either group. CONCLUSIONS: We found that the BlockBuster laryngeal mask has higher oropharyngeal leak pressure compared with Ambu AuraGain in a pediatric population.

Development of an institutional protocol for percutaneous dilatational tracheostomy in critically ill COVID-19 patients: Initial experience.

Background and Aims: Percutaneous dilatational tracheostomy (PDT) may improve the outcome in critically ill COVID-19 patients on mechanical ventilation. However, the timing of performing tracheostomy may be controversial, and it is an aerosol-generating procedure with a potential risk of viral exposure to healthcare workers. Material and Methods: An operational protocol for performing PDT was made and subsequently followed in a designated COVID-19 ICU. Critically ill adult patients on mechanical ventilators who underwent PDT were included in this retrospective cohort study. Case files were retrospectively reviewed and patient characteristics, clinical outcome, and procedure-related details were noted. Results: Forty-one patients were included in the analysis. The median age was 49 (39-67) years, and 41.5% of patients were females. The median duration of mechanical ventilation before tracheostomy was 10 (8-16) days, and the median (IQR) PaO2/FiO2 ratio on the day of PDT was 155 (125-180) mm Hg. Further, 48.8% of patients had transient desaturation to SpO2 <90%, and 41.5% survived to ICU discharge. None of the health care providers involved in PDT developed any symptoms of COVID 19. Conclusion: This descriptive study demonstrates the feasibility, implementation, and apparent safety of the PDT protocol developed at our institution.

Ten Practice Changes in COVID-19 Intensive Care Unit of a Tertiary Care Teaching Hospital in India during the Peak of Pandemic: Adapt and Improve.

During the peak of the coronavirus disease-2019 (COVID-19) pandemic, 10 practice-changing decisions were adopted which led to an improved standard of clinical care in the face of overwhelming burden to the healthcare setup. Formation of a control unit with the piggyback team, briefing before donning, replacement of personal protective equipment (PPE) with impermeable surgical gowns, a dedicated prone team and the prone bundle of care, weaning-extubation and tracheostomy protocol, online audiovisual family-patient meet, daily rounds by hospital infection control committee member, each one clean one policy, focused onsite training of healthcare support staff and discharge policy with post-discharge follow-up were the 10 important changes adopted.

Risk of SARS-CoV-2 Infection among Healthcare Providers Involved in Cardiopulmonary Resuscitation in COVID-19 Patients.

Cardiopulmonary resuscitation (CPR) is considered an aerosol-generating procedure. The aim of this study was to identify the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among healthcare providers (HCPs) involved in CPR in coronavirus 2019 (COVID-19) patients. An online and offline anonymous survey with a preformed questionnaire was conducted among the HCPs involved in the care of COVID-19 patients. HCPs who developed reverse transcription-polymerase chain reaction-positive confirmed COVID-19 and/or symptomatic influenza-like illness (ILI) within 14 days of their involvement in CPR of a confirmed COVID-19 patient were identified. Activities performed during CPR, the cumulative number of CPR performed, any breach in personal protective equipment (PPE), type of the mask used, use of any pharmacological prophylaxis, and any psychological impact among HCPs were also identified. A total of 393 HCPs participated in the survey; out of them, 197 HCPs participated in CPR at least once (CPR group) and the rest 196 did not (control group). Ten in the control group and five in the CPR group developed confirmed COVID-19 within the next 2 weeks; however, only one of these five had a breach in PPE during CPR. To conclude, participation in CPR does not increase the risk of SARS-CoV-2 infection in HCPs caring for the COVID-19 patients.

Epidemiological & clinical characteristics & early outcome of COVID-19 patients in a tertiary care teaching hospital in India: A preliminary analysis.

BACKGROUND & OBJECTIVES: In this study we describe the epidemiological data, comorbidities, clinical symptoms, severity of illness and early outcome of patients with coronavirus disease 2019 (COVID-19) from a tertiary care teaching hospital in New Delhi, India. METHODS: In this preliminary analysis of a prospective observational study, all adult patients admitted to the screening intensive care unit (ICU) of the institute who fulfilled the WHO case definition of COVID-19 and confirmed to have SARS-CoV-2 infection by reverse transcription-polymerase chain reaction were included. Demographics, clinical data and 24 h outcome were assessed. RESULTS: The preliminary analysis of 235 patients revealed that the mean age was 50.7±15.1 yr and 68.1 per cent were male. Fever (68.1%), cough (59.6%) and shortness of breath (71.9%) were the most common presenting symptoms. Hypertension (28.1%) and diabetes mellitus (23.3%) were the most common associated comorbid illnesses. Patients with mild, moderate, severe and critical illness were 18.3, 32.3, 31.1 and 18.3 per cent, respectively, at the time of ICU admission. The proportions (95% confidence interval) of patients requiring any form of oxygen therapy, oxygen therapy by high-flow nasal cannula and invasive mechanical ventilation were 77, 21.7 and 25.5 per cent, respectively, within 24 h of hospital admission. The 24 h ICU mortality was 8.5 per cent, and non-survivors had higher respiratory rate (P <0.01, n=198) and lower baseline oxyhaemoglobin saturation (P <0.001, n=198) at presentation and higher baseline serum lactate (P <0.01, n=122), total leucocyte count (P <0.001, n=186), absolute neutrophil count (P <0.001, n=132), prothrombin time (P <0.05, n=54) and INR (P <0.05, n=54) compared to survivors. INTERPRETATION & CONCLUSIONS: Nearly half of the patients presented with severe and critical disease and required high-flow nasal oxygen or invasive mechanical ventilation at admission. Severity of the presenting respiratory illness, haematological parameters and lactate rather than age or presence of comorbidity predicted early death within 24 h.
