RESUMO
OBJECTIVES: Literature states a higher self-contamination rate among healthcare workers (HCWs) while doffing personal protective equipment (PPE). During the Covid-19 pandemic, onsite trained observers were not always available to monitor PPE compliance. The remote audio-visual doffing surveillance (RADS) system has the potential to overcome this limitation. We aimed to compare the efficacy of this real-time RADS system against the onsite buddy system for monitoring the doffing of PPE. METHODS: This prospective, observational study was carried out at our tertiary care centre in northern India. 200 HCWs who cared for Covid-19 patients in the intensive care units/operation theatres were included. Group A included HCWs who performed doffing with the help of an onsite trained observer and group B included HCWs who performed doffing with the RADS system. An independent observer noted the error at any step using the CDC doffing checklist, in both groups. An online questionnaire to analyse the level of satisfaction post-doffing was also surveyed. RESULTS: The proportion of errors committed during doffing was significantly lower in group B compared to group A with a low relative risk of 0.34 (95% CI 0.22-0.51) (p < 0.001) (Figure 1A,B). In both groups, there was no difference in HCWs feedback regarding the ease of the system and fear of committing an error. Though the perceived quality of monitoring was felt better with onsite buddy, the overall confidence rating of being safe after doffing was better with the RADS system. CONCLUSION: Real-time RADS system may be more effective than the onsite buddy system for ensuring the safety of HCWs during doffing PPE. HCWs level of satisfaction related to the ease and anxiety with the monitoring systems were comparable. RADS system can reduce reliance on HCW resources and can integrate well into existing healthcare systems.

Background and Aims: Intra-abdominal insufflation of CO2 is associated with an increase of intracranial pressure (ICP). We conducted this randomized control trial to compare the impact of low vs standard pressure pneumoperitoneum on ICP through the ultrasonographic estimation of the optic nerve sheath diameter (ONSD). Material and Methods: Patients of age group 18-80 years planned for laparoscopic cholecystectomy were randomly allocated into two groups; group S (standard pressure of 12-16 mmHg) and group L (low pressure of 8-10 mmHg) on the basis of intra-abdominal pressures used for the surgery. All were administered general anesthesia and end-tidal carbon dioxide (ETCO2) was maintained between 35 and 40 mmHg and peak airway pressures less than 35 cmH2O. ONSD was measured in either eye at a point 3 mm posterior to the globe at following time intervals; baseline, 5 min after induction, 10 min after insufflation, 10 min after reverse Trendelenburg, intraoperatively during surgery and after exsufflation in the supine position. Results: The demographic profile and operative times were comparable. ONSD was measured in 100 patients in each group for both the eyes and no patient had values above the cutoff value of 5.0 mm. No significant difference in the ONSD was observed at the above mentioned time intervals between the groups. There was a statistically significant lower value of the heart rate and mean arterial pressure in the low-pressure group. Conclusion: Intra-abdominal insufflation of CO2 at standard and low pressures does not increase ICP in short duration surgeries and thus both the pressures can be safely used in adult patients operated in reverse Trendelenburg position. Advantages of low pressure were limited to better hemodynamic control.
RESUMO
Continuous monitoring of 5-lead electrocardiogram is a basic standard of care (included under standard ASA monitor) in the operating room and electrocautery interference is a common phenomenon. Clinical signs, along with monitored waveforms from other simultaneously monitored parameters may provide us clues to differentiate artifacts from true changes on the electrocardiogram. An improved understanding of the artifacts generated by electrocautery and their identifying characteristics is important to avoid misinterpretation, misdiagnosis, and hence mismanagement. This case report highlights the artifacts in electrocardiogram induced by electrocautery.

This case represents anaesthetic challenges while managing a neonate having a congenital cardiac anomaly with incidental stridor for the non-operating room anaesthesia (NORA). Anaesthesia management of neonates is demanding even for experienced anaesthetists in terms of vascular access, airway management, relatively poor respiratory reservoir and transitional cardiac physiology. Neonate having cyanotic congenital heart disease with abnormal cardiac physiology demands further attention. In children with congenital heart disease, difficult intubation remains a possibility as they are more often associated with airway anomalies. NORA has its own set of anaesthesia challenges related to a lack of adequate anaesthesia equipment and monitoring devices, a limited and unfamiliar workspace, lack of trained support staff along with more medically complex patients. Recently there has been concern regarding the safety of anaesthetic agents in children < 3 years. So, techniques are being developed to promote immobilisation without using anaesthesia in short procedures. One such technique is the "feed and wrap" technique where feeding and swaddling induce natural sleep in infants. Here, we have used the "feed and wrap technique" in a 24-day-old neonate having supracardiac total anomalous pulmonary venous return with incidental stridor posted for contrast-enhanced computed tomography angiography.
RESUMO
Background: Data on outcomes of coronavirus disease 2019 (COVID-19) in pregnancy are scarce, although they represent a unique physiological state affecting both the mother and child. We present collated data from a tertiary care center in North India, encompassing the outcome, clinical characteristics, and management of these patients. Materials and Methods: Parturients ≥ 18 years old, with COVID-19 reverse transcriptase polymerase chain reaction positive for severe acute respiratory syndrome coronavirus 2, requiring intensive care unit (ICU) admission at a tertiary care hospital were included. Data were retrospectively collected from April 2020 to November 2021. Results: In all, 26 parturients were admitted to ICU with COVID-19. Five patients were admitted during the first wave, and all were asymptomatic. Twenty-one patients presented during the second wave (March 2021 onward), among which four were asymptomatic and 17 symptomatic (all with severe pneumonia). Three patients presented in the second trimester, all with critical disease, out of which one did not survive. Two patients had twin gestation, and others were singleton pregnancies. Seven patients (27%) were primigravida, and five patients (19.2%) had more than third pregnancy. Twenty critically ill women (77%) delivered during the hospital stay. Six patients died during the second wave, and four deaths (66.7%) were because of COVID-19 acute respiratory distress syndrome (ARDS). Conclusions: The number of admissions and mortality related to COVID-19 ARDS was higher in the second wave than in the first. We report the safe use of remdesivir and tocilizumab in our patients.
RESUMO
BACKGROUND: Literature shows fentanyl reduces the median effective concentration (EC50) of propofol when used for various noxious stimuli. However, fentanyl combined with propofol has a depressive effect on haemodynamics. We hypothesise that low dose dexmedetomidine will reduce the propofol requirement for induction with better haemodynamic profile compared with fentanyl. MATERIAL AND METHODS: 120 ASA I/II adult patients, of age group 20 to 60 years, scheduled for elective day-care surgeries under general anaesthesia were randomised to three equally distributed groups as group D, group F and group S (control) of 40 patients each. They received infusions of dexmedetomidine 0.5 mcg/kg, fentanyl 1.5 mcg/kg and normal saline (control) respectively over 5 min prior to induction with propofol TCI (Marsh model). EC50 of propofol (primary objective) for I-gel insertion in each group was determined from the estimated effect site concentration (Ce), using Dixon's up-and-down method . Secondary objectives were propofol dose requirement and percentage change in haemodynamics during induction. RESULTS: Our study demonstrates that low-dose dexmedetomidine premedication achieves more reduction in the EC50 (2.4 µg/ml, IQR 2.4 - 2.6 µg/ml, 95% CI 2.40 - 2.55 µg/ml) and dose of propofol (1.14 ± 0.28 mg/kg, 95% CI 1.05 - 1.23 mg/kg), for I-gel insertion, than that can be achieved by the use of fentanyl with propofol (EC50 of 3.0 µg/ml IQR 3.0 - 3.05 µg/ml, 95% CI 2.94 - 3.11 µg/ml; propofol dose 1.89 ± 0.55 mg/kg, 95% CI 1.72 - 2.07 mg/kg ) without any significant change in the haemodynamics. CONCLUSION: Low-dose dexmedetomidine when compared with fentanyl significantly reduce the EC50 and dose of propofol required for I-gel insertion with propofol TCI, without much change in the haemodynamic profile. CLINICAL TRIAL REGISTRATION NUMBER: CTRI/2019/03/018003.

Catatonic patients may develop deep vein thrombosis (DVT) and pulmonary embolism (PE) due to prolonged periods of immobility. These life-threatening conditions demand prompt recognition and management. We describe the case of a patient with catatonia who presented to anesthesia for electroconvulsive therapy (ECT) at the outset of the current coronavirus disease 2019 pandemic. She complained of breathing difficulty and was suspected to have COVID-19 infection. On further evaluation, she was found to have DVT and PE and required oxygen therapy and intensive care management. The diagnostic delay in our patient would have probably not occurred, had it not been for the existing pandemic situation.

Background The importance of optimal acid-base balance during renal transplant surgeries cannot be stressed enough. Optimal preload and electrolyte balance is important in maintaining this. There has been a debate on the choice of perioperative crystalloids in renal transplant surgeries over the past decades. Normal saline (0.9% saline) is more likely to cause hyperchloremic acidosis when compared to balanced salt solutions (BSS) with low chloride content whereas BSS may cause hyperkalemia. We aim to compare the safety and efficacy of normal saline (NS), Ringer's lactate (RL) and Plasmalyte (PL) on acid-base balance and electrolytes during living donor kidney transplantation. Materials and methods Patients were randomized to NS group (n = 60), RL group (n = 60) and Plasmalyte group (n = 60). Arterial blood samples were collected for acid-base analysis after induction of anaesthesia (T0), prior to clamping the iliac vein (T1), 10 minutes after reperfusion of the donated kidney (T2) and at the end of surgery (T3). In addition, serum creatinine and 24-hour urine output were recorded on postoperative days one, two and seven. Results There was a statistically significant difference (p < 0.001) in the pH at the end of surgery between the three groups with the NS group being more acidotic (pH 7.29 ± 0.06, 95% CI 7.27-7.32), although this was not clinically relevant. This was explainable by the parallel increase in chloride in the NS group. Early postoperative graft functions in terms of serum creatinine, urine output and graft failure requiring dialysis were not significantly different between the groups. Conclusion Balanced salt solutions such as Plasmalyte and Ringer's lactate are associated with better pH and chloride levels compared to normal saline when used intraoperatively in renal transplant patients. This difference, however, does not appear to have any bearing on graft function. Plasmalyte seems to maintain a better acid-base and electrolyte balance, especially during the postreperfusion period.
RESUMO
Background Very little has been reported about health care workers' (HCWs) adherence to the Centers for Disease Control and Prevention (CDC) guidelines of doffing personal protective equipment (PPE) amid the COVID-19 pandemic. Real-time remote audio-visual doffing surveillance (RADS) system for assisting doffing might reduce the risk of self-contamination. We used this system to determine the incidence of the breach in biosafety during doffing of PPE among HCWs involved in the care of Covid-19 patients. Methods A total of 100 HCWs were enrolled in this observational study who performed duties in the COVID intensive care unit (ICU) of our tertiary care centre. With a real-time RADS system, trained observers from remote locations assisted HCWs during doffing of PPE and noted breach at any step using the CDC doffing checklist. The breach was considered major if committed during removal of gloves/gown/N-95 or if ≥3 errors occurred in any other steps. Results Overall, 40% of the HCWs committed a breach during doffing at least one step. The majority of the errors were observed during hand hygiene (34%), followed by glove removal (12%) and N-95 removal (8%). Nineteen percent of HCWs committed the major breach, out of which 37.5% were done by house-keeping sanitation staff (p = 0.008 and RR 2.85; 95% CI of 1.313-6.19), followed by technicians (22.5%), nursing staff (16.7%) and resident doctors (6.5%). Conclusions Performing doffing using a real-time RADS system is associated with a relatively low incidence of a breach in biosafety compared with earlier studies using an onsite standard observer. Overall adherence of HCWs to the CDC guidelines of doffing PPE was satisfactory. This study highlights the importance of the RADS system during doffing of PPE in a health care setting amid the COVID-19 pandemic.
RESUMO
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.
RESUMO
Maffucci syndrome is an extremely rare, sporadic, and nonhereditary disease characterized by enchondromatosis, bony abnormalities, and vascular malformations. We report a successful anaesthetic management of an adult patient with Maffucci syndrome scheduled for surgical excision of parathyroid adenoma, who had numerous enchondromas, haemangiomas, and skeletal deformities involving different parts of the body and posing significant challenge during positioning, securing intravenous access, and insertion of endotracheal tube. Awareness about this syndrome is of paramount importance because similar patients may be encountered with increasing frequency for incidental or corrective surgeries.
RESUMO
BACKGROUND: To ensure patient safety, it is important to regularly assess the knowledge and practical skills of anesthesia trainees. This study was conducted to evaluate the competency of the residents and the impact of various corrective measures in the form of didactic lectures and clinical skill demonstrations on the conduct of various procedural skills by the residents. MATERIALS AND METHODS: Ninety-five junior residents were enrolled in this study. Assessment of competency of 1st, 2nd, and 3rd year residents in performing various procedure skills of anesthesia was done in two stages using procedure specific checklist (PSC) and Global Rating Scales (GRSs). Preliminary results of the first assessment (Score 1) were discussed with the residents; deficiencies were identified and corrective measures suggested by didactic lectures and clinical skill demonstrations which were followed by a subsequent assessment after 3 months (Score 2). RESULTS: There was a statistically significant improvement in the PSC and GRS scores after corrective measures for all the procedural interventions studied. Percentage increase in scores was maximum in 1st year (42.98 ± 6.62) followed by 2nd year (34.62 ± 5.49) and minimum in 3rd year residents (18.06 ± 3.69). The percentage increase of scores was almost similar for all subset of procedural skills; low, intermediate, and high skill anesthetic procedures. CONCLUSION: For assessment of procedural skills of residents, use of PSC and GRS scores should be incorporated and the same should be used to monitor the impact of various corrective measures (didactic lectures and clinical skill demonstrations) on the conduct of various procedural skills by the resident.
