RESUMO

Over the last decade, the use of extracorporeal membrane oxygenation (ECMO) has increased significantly. In some centers, ECMO has been deployed to manage perioperative emergencies and plays a role in facilitating high-risk thoracic, airway, and trauma surgery, which may not be feasible without ECMO support. General anesthesiologists who usually manage these cases may not be familiar with the initiation and management of patients on ECMO. This review discusses the use of ECMO in the operating room for thoracic, airway, and trauma surgery, as well as obstetric and perioperative emergencies.

RESUMO

BACKGROUND: In healthcare, quality improvement (QI) tools are predominantly used to address human, system and process factors to improve clinical care. We believe that QI tools can also be used to address similar factors in medical education, to facilitate improvement in learning outcomes and competencies for new junior doctors in a postgraduate medical education program in our anaesthesia and critical care unit. METHODS: A stepwise competency checklist was devised to guide the learning and monitor the percentage who had completed the required learning activities and tests at the end of each month. This was tabulated as monthly competency scores, and served as a measure of effectiveness of the education program. QI tools, namely the Fishbone diagram and Pareto chart, were used to identify modifiable root causes and prioritise interventions. RESULTS: Monthly competency scores ranged 30-50% at baseline, and improved to 60-75% after 6 months, with the implementation of a series of QI interventions. CONCLUSION: QI tools were utilised to guide education interventions, with consequent improvement in the monthly competency scores of our junior doctors. Focused improvement cycles that are aligned to learning outcomes are key to the success of using QI tools in medical education.

RESUMO

INTRODUCTION: Pulmonary veno-occlusive disease (PVOD) is a rare form of pulmonary hypertension. It is often underdiagnosed or misdiagnosed as idiopathic pulmonary arterial hypertension (PAH). Inappropriate treatment may cause worsening of symptoms which may lead to fatal outcomes. Anesthetic considerations and management for pulmonary hypertension are well described, but few anesthesiologists are aware of the entity of PVOD and its management. PATIENT CONCERNS: We report a case of PVOD in a 73-year-old female who was on concurrent aspirin and anagrelide, requiring emergent open femoral hernia repair. DIAGNOSIS: PVOD and incarcerated femoral hernia INTERVENTION:: Combined spinal-epidural (CSE) was performed to enable the surgery. OUTCOME: Surgery was completed successfully under central neuraxial anesthesia and the patient remained stable and comfortable throughout, avoiding the need for general anesthesia. Due to the concurrent aspirin and anagrelide therapy, significant bleeding from the CSE puncture site was observed immediately post-operatively. This was resolved with external manual compression and withholding the aspirin and anagrelide. Patient remained well without neurological deficit and was discharged postoperative day seven. LESSONS: It is important to differentiate PVOD from PAH due to the controversial use of pulmonary vasodilators in PVOD. Pulmonary vasodilator is commonly used to treat acute pulmonary hypertension in PAH but its usage may lead to pulmonary edema in patients with PVOD. Hence, with no ideal treatment available, the avoidance of general anesthesia is crucial to prevent acute pulmonary hypertensive crisis in patient with PVOD. However, this needs to be weighed against the elevated risk of central neuraxial bleeding when performing a CSE in a patient on concurrent aspirin and anagrelide therapy. Calculated decision-making considering the risks and benefits of all alternatives should be carried out in such a scenario, and measures should be taken in anticipation of the potential consequences of the eventual decision. CONCLUSION: It is important to differentiate PVOD from PAH. PVOD has unique anesthetic considerations due to the controversial use of pulmonary vasodilators. This case also emphasizes the importance of active anticipation of potential issues and adequate follow up.

RESUMO

BACKGROUND AND AIM: COVID-19 pandemic has resulted in an unprecedented increased usage of Personal protective equipment (PPE) by healthcare-workers. PPE usage causes headache in majority of users. We evaluated changes in cerebral hemodynamics among healthcare-workers using PPE. METHODS: Frontline healthcare-workers donning PPE at our tertiary center were included. Demographics, co-morbidities and blood-pressure were recorded. Transcranial Doppler (TCD) monitoring of middle cerebral artery was performed with 2-MHz probe. Mean flow velocity (MFV) and pulsatility index (PI) were recorded at baseline, after donning N95 respirator-mask, and after donning powered air-purifying respirator (PAPR), when indicated. End-tidal carbon-dioxide (ET-CO2) pressure was recorded for participants donning PAPR in addition to the N95 respirator-mask. RESULTS: A total of 154 healthcare-workers (mean age 29 ± 12 years, 67% women) were included. Migraine was the commonest co-morbidity in 38 (25%) individuals while 123 (80%) developed de-novo headache due to N95 mask. Donning of N95 respirator-mask resulted in significant increase in MFV (4.4 ± 10.4 cm/s, p < 0.001) and decrease in PI (0.13 ± 0.12; p < 0.001) while ET-CO2 increased by 3.1 ± 1.2 mmHg (p < 0.001). TCD monitoring in 24 (16%) participants donning PAPR and N95 respirator mask together showed normalization of PI, accompanied by normalization of ET-CO2 values within 5-min. Combined use of N95 respirator-mask and PAPR was more comfortable as compared to N95 respirator-mask alone. CONCLUSION: Use of N95 respirator-mask results in significant alterations in cerebral hemodynamics. However, these effects are mitigated by the use of additional PAPR. We recommend the use of PAPR together with the N95 mask for healthcare-workers doing longer duties in the hospital wards.
