Interventional Radiology Procedures for COVID-19 Patients: How we Do it.

With astonishing speed, COVID-19 has become a global pandemic. As it is uncertain when the pandemic will be controlled, it is crucial for procedurists of all stripes to be familiar and confident in performing procedures for COVID-19 patients to prevent intra-hospital infection. In this article, we will detail our approach on how to perform interventional procedures for COVID-19 patients at the bedside in the isolation room and with the patient transferred to the interventional radiology centre. These workflows have been developed in conjunction with multiple other stakeholders within our hospital, drawing from valuable lessons we have learnt from the SARS outbreak of 2003.

Preparing for a COVID-19 pandemic: a review of operating room outbreak response measures in a large tertiary hospital in Singapore.

The coronavirus disease 2019 (COVID-19) outbreak has been designated a public health emergency of international concern. To prepare for a pandemic, hospitals need a strategy to manage their space, staff, and supplies so that optimum care is provided to patients. In addition, infection prevention measures need to be implemented to reduce in-hospital transmission. In the operating room, these preparations involve multiple stakeholders and can present a significant challenge. Here, we describe the outbreak response measures of the anesthetic department staffing the largest (1,700-bed) academic tertiary level acute care hospital in Singapore (Singapore General Hospital) and a smaller regional hospital (Sengkang General Hospital). These include engineering controls such as identification and preparation of an isolation operating room, administrative measures such as modification of workflow and processes, introduction of personal protective equipment for staff, and formulation of clinical guidelines for anesthetic management. Simulation was valuable in evaluating the feasibility of new operating room set-ups or workflow. We also discuss how the hierarchy of controls can be used as a framework to plan the necessary measures during each phase of a pandemic, and review the evidence for the measures taken. These containment measures are necessary to optimize the quality of care provided to COVID-19 patients and to reduce the risk of viral transmission to other patients or healthcare workers.

RéSUMé: L'épidémie liée au coronavirus 2019 (COVID-19) a été qualifiée d'urgence de santé publique de portée internationale. La préparation face à une pandémie nécessite de la part d'un hôpital l'élaboration de stratégies pour gérer ses infrastructures, ses processus, son personnel et ses patients; il doit notamment instaurer des mesures de prévention des infections pour réduire la transmission intrahospitalière. Pour un bloc opératoire, ces préparations impliquent la participation de nombreux acteurs et peuvent constituer un véritable défi. Nous décrivons les mesures prises en réponse à l'épidémie par le département d'anesthésie qui sert le plus grand hôpital universitaire de soins aigus (1700 lits) de Singapour (Singapore General Hospital) et un plus petit hôpital régional (Sengkang General Hospital). Cela a été obtenu grâce à des expertises d'ingénierie, telles que l'identification et la préparation d'une salle d'opération en isolation, des mesures administratives telles que la modification du déroulement des activités et des processus, l'introduction d'équipements de protection individuels pour le personnel et ­ enfin ­ la formulation de lignes directrices cliniques pour la gestion anesthésique. La simulation a été importante pour évaluer la faisabilité de toutes nouvelles modifications des salles d'opération ou d'un nouveau flux de travail. Dans le contexte des différentes phases d'une pandémie, nous discutons de l'application d'une hiérarchie de contrôles comme cadre des modifications à chaque niveau de contrôle et nous passons aussi en revue les données probantes soutenant les mesures prises. Ces mesures de confinement sont nécessaires pour optimiser la qualité des soins procurés aux patients atteints de COVID-19 et pour réduire le risque de transmission du virus à d'autres patients ou employés du domaine de la santé.

High Le Fort I and bilateral split sagittal osteotomy in Crouzon syndrome.

Crouzon syndrome is a rare, autosomal dominant disease from a fibroblast growth factor receptor 2 gene mutation, characterized by premature craniosynostosis, hypertelorism, orbital proptosis, psittichorina, hypoplastic maxilla, and mandibular prognathism. We present an adult 32-year-old Crouzon syndrome patient who underwent an elective High Le Fort I and bilateral split sagittal osteotomy for midface advancement with a background of jaw malocclusion and obstructive respiratory symptoms. The operation features a potential dynamic movement of the secured airway in the surgical field and close proximity to exposed ocular structures. Permissive hypotensive anesthesia was employed to improve the surgical field and reduce intraoperative blood loss and dose of long-acting opioids. He was extubated at the end of an uneventful surgery and was monitored in the high dependency overnight before he was discharged to the general ward. Perioperative issues include potential difficult airway management; ocular, auditory, and neurological injury prevention; surgery-specific anesthetic technique; and postoperative analgesia. Understanding the multisystemic issues facilitates the dynamic anesthetic management during surgery. Good communication among the multidisciplinary team is essential to ensure a successful operation and uneventful recovery.
