Operating room preparation for COVID-19

Operating room preparation for COVID-19

Ti et al. published what they do preparing an operating room (OR) when a confirmed or suspected COVID-19 patient needs an operation 1).

An operating room with a negative room pressure environment located at a corner of the operating complex, and with separate access, is designated for all confirmed (or suspected) COVID-19 cases. The OR actually consists of five interconnected rooms, of which only the anteroom and anesthesia induction rooms have negative atmospheric pressures. The OR proper, preparation and scrub rooms all have positive pressures.

Understanding the airflow within the OR is crucial to minimizing the risk of infection.

The same OR and the same anesthesia machine will only be used for COVID-19 cases for the duration of the epidemic. An additional heat and moisture exchanger (HME) filter is placed on the expiratory limb of the circuit. Both HME filters and the soda lime are changed after each case. The anesthetic drug trolley is kept in the induction room. Before the start of each operation, the anesthesiologist puts all the drugs and equipment required for the procedure onto a tray to avoid handling of the drug trolley during the case. Nevertheless, if there is a need for additional drugs, hand hygiene and glove changing are performed before entering the induction room and handling the drug trolley.

A fully stocked airway trolley is also placed in the induction room. As far as possible, disposable airway equipment is used. The airway should be secured using the method with the highest chance of first-time success to avoid repeated instrumentation of the airway, including using a video-laryngoscope.

Equipment in limited supply such as bispectral index monitors or infusion pumps may be requested but need to be thoroughly wiped down after use.

Hospital security is responsible for clearing the route from the ward or intensive care unit (ICU) to the OR, including the elevators. The transfer from the ward to the OR will be done by the ward nurses in full personal protective equipment (PPE) including a well-fitting N95 maskgoggles or face shieldsplash-resistant gown, and boot covers. For patients coming from the ICU, a dedicated transport ventilator is used. To avoid aerosolization, the gas flow is turned off and the endotracheal tube clamped with forceps during the switching of ventilators. The ICU personnel wear full PPE with a powered air-purifying respirator (PAPR) for the transfer. In the induction room, a PAPR is worn during induction and reversal of anesthesia for all personnel within 2 m of the patient. For operative airway procedures such as tracheostomy, all staff keep their PAPR on throughout the procedure.

During the procedure, a runner is stationed outside the OR if additional drugs or equipment are needed. These are placed onto a trolley that will be left in the ante room for the OR team to retrieve. This same process in reverse is used to send out specimens such as arterial blood gas samples and frozen section specimens. The runner wears PPE when entering the ante room.

Personnel exiting the OR discard their used gowns and gloves in the ante room and perform hand hygiene before leaving the ante room. Any PAPR will be removed outside the ante room. Patients who do not require ICU care postoperatively are fully recovered in the OR itself. When the patient is ready for discharge, the route to the isolation ward or ICU is again cleared by security.

A minimum of one hour is planned between cases to allow OR staff to send the patient back to the ward, conduct through decontamination of all surfaces, screens, keyboard, cables, monitors, and anesthesia machine. All unused items on the drug tray and airway trolley should be assumed to be contaminated and discarded. All staff have to shower before resuming their regular duties. As an added precaution, after confirmed COVID-19 cases, a hydrogen peroxide vaporizer will be used to decontaminate the OR.

The American Board of Neurological Surgery oral examination has undergone periodic review and revision over the years, with a new format instituted in spring 2017. This review book is specifically geared to the new format. The ABNS oral examination process is relevant, rigorous, and of value to the neurosurgical specialty and the public, ensuring neurosurgeons meet the highest standards of practice.

Neurosurgical Review: For Daily Clinical Use and Oral Board Preparation by Vasilios A. Zerris and distinguished contributors is a multimodal and a visually rich prep tool for the ABNS exam. The resource provides a unique approach to studying and melding online didactic materials with audio-enhanced charts. Readers can use the material as a completely online exam prep course with audio or use the print version as a quick reference guide.

Key Features

Charts and schematics provide an excellent learning tool and study prep The high yield and easy to memorize format helps readers “visualize” knowledge Audio files enhance the ability to create a mental framework, thereby increasing comprehension and retention of content Cases presented at the end of each chapter focus primarily on core material tested in the general neurosurgery ABNS exam session taken by all candidates irrespective of their declared subspecialty This is an essential textbook for neurosurgical residents, fellows, and practitioners prepping for the ABNS boards. It also serves as a user-friendly refresher of fundamental knowledge all neurosurgeons need to know.

Board certification by the American Board of Neurological Surgery is considered the gold standard for neurosurgeons practicing in the U.S. The ABNS primary examination requires many months of preparation, and passing it is both a significant accomplishment and integral component in becoming board certified. Contributions from current neurosurgical residents and seasoned practitioners infuse this book with a well-rounded perspective. Having been there and done that, the authors incorporated what they felt was missing from board review books when they sat for the exam – resulting in a “bucket list” study guide.
The review is organized by neurosurgical topic with 20 chapters equally divided among questions followed by answers. Starting with physiology and anatomy, each chapter methodically covers core topics including radiology, neurology, pathology/histology, ophthalmology, and more. The authors provide brief explanations and pearls that accompany each question, which provide a solid springboard for delving deeper into any given topic. The easy-to-follow format enables residents to partake in long study sessions or tackle just a question or two in the midst of a busy day of neurosurgical service.
Key Highlights

  • More than 1,300 questions reflect key concepts in the ABNS primary exam
  • Enhanced with more than 350 images, most in color, which reflect the computerized, image-rich format of the current exam
  • A full-length practice test at the end of the book mirrors the cadence and time constraints of the actual exam
  • Explanations of correct and incorrect answers facilitate learning and retaining vast amounts of material

This comprehensive board review book will help neurosurgical residents of all levels prepare thoroughly for the March exam. It is a one-stop self-assessment tool for any neurosurgeon who endeavors to attain and maintain ABNS certification.
