COVID-19 which emerged in Wuhan, China has rapidly spread all over the globe and the World Health Organisation has declared it a pandemic. COVID-19 disease severity shows variation depending on demographic characteristics like age, history of chronic illnesses such as cardio-vascular/renal/respiratory disease; pregnancy; immune-suppression; angiotensin converting enzyme inhibitor medication use; NSAID use etc but the pattern of disease spread is uniform – human to human through contact, droplets and fomites. Up to 3.5% of health care workers treating COVID-19 contact an infection themselves with 14.8% of these infections severe and 0.3% fatal. The situation has spread panic even among health care professionals and the cry for safe patient care practices are resonated world-wide. Surgeons, anesthesiologists and intensivists who very frequently perform endotracheal intubation, tracheostomy, non-invasive ventilation and manual ventilation before intubation are at a higher odds ratio of 6.6, 4.2, 3.1 and 2.8 respectively of contacting an infection themselves. Elective surgery is almost always deferred in fever/infection scenarios. A surgeon and an anesthesiologist can anytime encounter a situation where in a COVID-19 patient requires an emergency surgery. COVID-19 cases requiring surgery predispose anesthesiologists and surgeons to cross-infection threats. This paper discusses, the COVID-19 precautionary outlines which has to be followed in the operating room; personal protective strategies available at present; methods to raise psychological preparedness of medical professionals during a pandemic; conduct of anesthesia in COVID-19 cases/suspect cases; methods of decontamination after conducting a surgery for COVID-19 case in the operating room; and post-exposure prophylaxis for medical professionals.

   Introduction Top

Emerging and re-emerging diseases[1] pose a constant threat to public health and add to the work exigencies of health-care professionals worldwide. Among these, air-borne or droplet-borne infections are the most feared considering their contagious nature and fast transmission.[2],[3],[4],[5],[6] Influenza and parainfluenza virus,[7] respiratory syncytial virus,[8] Cytomegalovirus, hanta virus,[9] and coronavirus infections are among those re-emerging infections that predispose to predominantly to lower respiratory infections. These infections can be self-limited to a tracheo-bronchitis in healthy individuals, but immunocompromised patients, elderly with multiple disease comorbidities, and pregnant females are more likely to develop life-threatening pneumonitis and adult respiratory distress syndrome.[10],[11]

Coronavirus disease 2019 (COVID-19) is a novel pneumonia syndrome which was first identified clustered around the Huanan Seafood market in Wuhan, China, in December 2019.[12],[13] The causative agent is identified as a beta-coronavirus named as severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), which is one among the seven strains of this virus that causes human infection.[14] Most beta-coronaviruses are endemic ones that causes common cold, but the fatal strains of beta-CoV caused the 2002 SARS outbreak (case fatality 10%),[15] 2012 Middle East respiratory syndrome (case fatality 40%),[16] and the present COVID-19 (case fatality 2%).[17] The number of patients generated after exposure to one COVID-19 patient is estimated to be 2.2–3.6.[18] Phylogenetic analysis traced to bats and ant eaters as the original host of the causative agent of 2019-nCoV. Human–human transmission of SARS-CoV-2 through droplet, fomites, and contact was identified by January 2020.[19] The 2019-nCoV rapidly spread internationally to almost all countries and territories of the globe.[20] As of April 8, 2020, 1,353,361 patients are infected globally and 79, 235 patients sustained mortality. The Indian statistics reveal 5194 patients infected and 149 mortalities as of April 9, 2020.[17] Considering the rapid spread, unavailability of treatment/vaccine,[21] and lethality of disease in vulnerable population group, the Government of India has announced nationwide shutdown and “curfew.”[22]

Infected individuals of 2019-nCoV are the main source of COVID-19 transmission at present.[23] Doctors, especially surgeons, anesthesiologists and intensivists, nurses, and other health-care workers, are at higher risk of droplet infections while caring for COVID-19 patients. Early statistics based on the Wuhan experience have shown up to a 3.5% of health-care workers treating COVID-19 contracting an infection themselves, with 14.8% of these infections severe and 0.3% fatal.[13] Physician fatality after hospital-acquired COVID-19 has also been reported from Wuhan.[24],[25] Surgeons, anesthesiologists, and intensivists, who very frequently perform endotracheal intubation, tracheostomy, noninvasive ventilation, and manual ventilation before intubation, are at a higher odds ratio of 6.6, 4.2, 3.1, and 2.8, respectively, of contracting an infection themselves.[26],[27],[28] In this review, we intend to examine the various methods of safely anesthetizing and providing intraoperative care to a COVID-19 patient. There has been an exodus of literature on COVID-19 ever since January 2020, and as the disease is still spreading in its full fury, we are afraid that our review can be “old” by the time it is published, though we have made our best efforts to keep abreast with the most recent recommendations in this field.

   Literature Search Top

We performed a PubMed and Google Scholar literature search using single text word and combinations of MeSH terms “COVID-19,” “SARS-CoV-2,” “2019-nCoV,” “Anaesthesia,” “Corona virus,” and “Emergency Surgery” from the year 2000 to April 2020. Relevant articles were collected electronically, and the references of those were manually searched further. The recommendations of the Chinese Society of Anaesthesiology based on their Wuhan experience,[29] Association of Anaesthetists of Great Britain,[30],[31] and selected institutional guidelines[32] were imbibed into for preparing this review.

   Psychological Preparation of Doctors, Nurses, and Health-Care Workers Top

Elective surgery is almost always deferred in fever/infection scenarios. A surgeon and an anesthesiologist can anytime encounter a situation wherein a COVID-19 patient requires an emergency surgery.[33] Appraisal programs for doctors; health-care worker training; teaching social distancing at society level and workplace; adherence to proper hand hygiene practice; and psychological preparation are etiquette to prevent self- and cross-contamination. Novel social media applications can be effectively used to promote motivational message and ensure that images/videos of good practice models reach all health-care professionals. This is more relevant in the context that in pandemics like COVID-19, almost all hospitals are operating with limited staff, and there are restrictions imposed by state machinery on gathering of people, which itself is a factor facilitating airborne disease spread. The institutional mental health guidelines can be framed and distributed to doctors and health-care workers using novel social media applications to help them cope up with the stressful work atmosphere. The mental health and stress management guidelines we use at our institution[34] are shown in [Table 1].

   Personal Protective Equipment Top

The classification and user guidelines for personal protective equipment (PPE) are shown in [Table 2]. A level III scaled PPE is mandatory while anesthetizing any patient with COVID-19.[35],[36] The merits of a positive pressure respirator or a powered air-purifying respirator (PPAR) over the N95/FFP2 mask are controversial at present.[37] In our scenario, the availability of PPAR is limited; hence, the use of N95/FFP2 mask gains an upper edge. Aerosol-generating clinical procedures such as endotracheal intubation have the highest risk of cross contamination. The anesthesiologist and the surgeon should understand that commonly performed clinical procedures can be cumbersome while using a PPE, and be psychologically prepared to meet the difficult situation. The PPE should be donned in the following sequence – put on scrubs and hair cover → perform hand wash → wear N95/FFP2 mask → wear inner gloves → wear coverall → wear eye protection (goggles/face shield) →wear foot protection → wear isolation gown → wear outer gloves → test the fit of the PPE components → ready to pass through. The PPE gowns may be prelabeled with the name of team member wearing it for ease of personal identification.[38] PPE should be donned in designated donning zone of the operation theater complex. The donning procedure needs to be monitored and can be assisted by an infection control nurse. Mock drills for donning and doffing of PPE should be conducted in anticipation as a part of hospital preparedness.[39],[40],[41],[42]

   Operating Room Preparation Top

During the pandemic, dedicated operating room (OR) only for operating COVID-19 cases should be identified in the hospital. Such ORs should be labeled as “Septic OR” or “Infectious OR” with discretion of personnel entry inside. A summary of standard recommendations [Table 3] to be adhered to while undertaking a case of COVID-19 for surgery shall be pasted in multiple areas of the OR to facilitate easy recollection of each team member. Such pamphlets shall be a concise statement of institutional practice guidelines and are not be too extensive. The OR complex should have separate entry/exit area; donning and doffing area for PPE; and bath areas. Negative-pressure ORs[43],[44] are ideally suited for COVID-19 cases, however the availability of such ORs is relatively scarce. Hence, positive pressure air circulation system in the septic OR is ideally to be kept off. The OR staff can easily get exhausted wearing the PPE in humid weathers and so the use of split air conditioners in the OR is at the discretion of the operating team subject to satisfactory decontamination of the OR after the surgery. The anesthesia machine dedicated for COVID-19 cases shall have a heat and moisture exchange (HME) filter at the patient end; and a high-quality bacterial and viral filter[45] should be attached to the machine end at expiratory port [Figure 1]. Gas sampling for capnography should be at the machine side of the HME filter. These filters need be replaced after every 3–4 h of use. High-quality filters offer a >99.99% viral filtration efficacy (VFE).[46],[47] Adding another viral filter between the machine end and inspiratory port can be advised but not necessary to protect the machine from the patient nor to protect the patient if the machine is kept clean.[48],[49]

   Preoperative Preparation Top

Clinical categorizations of cases during the COVID-19 pandemic based on clinical features of patients[34],[50] are described in [Table 4]. Early research has shown that older age group COVID-19 patients have a higher viral load in their throat swab samples.[51] Younger individuals within 1 week of symptom onset also have higher viral loads.[52] Critically ill patients may act as viral “shedders,” which is directly related to their infective viral load. Sputum samples show higher viral load compared to throat samples. Anesthesiologists are likely to receive (a) laboratory-confirmed COVID-19 cases, (b) suspect cases, (c) high-, and (d) low-risk contacts of laboratory-confirmed cases to the emergency OR [Table 5]. The exact patient definition is to be confirmed with the hospital COVID-19 committee before shift-in of patient to the OR. At this point of time, it is unclear whether the precautions that are adhered to for laboratory confirmed COVID-19 cases and suspect COVID-19 cases need be extended for intraoperative care of asymptomatic high-risk and low-risk contact individuals on home quarantine, though it is prudent to practice adherence to PPE universally in all symptomatic contacts irrespective of laboratory test being negative.

Only “lifesaving” or “limb-saving” emergency surgery should be undertaken in COVID-19 cases with active infection. COVID-19 infection is not an indication for emergency caesarean section or pharmacologic induction of labor. The decision to proceed with surgery should be after a joint decision of a “COVID committee” comprising of senior surgeons, anesthesiologists, and head of the institution. Time-sensitive surgery that can be postponed shall be done after the quarantine period of 14 days for cases with mild symptoms and 28 days for cases with severe symptoms, weighing the patient risk versus benefit by the “COVID committee.”

The COVID-19 patient scheduled for emergency surgery should be wheeled directly to the OR and there shall be no waiting in the premedication room. A brief history and clinical and airway examination can be undertaken inside the septic OR so as to facilitate the most minimum contamination. The anesthesia implications of novel pharmacotherapy in COVID-19[53],[54],[55] is summarized in [Table 6]. Transportation of patient to OR shall be done only after a telephonic confirmation of “ready” message is passed on from “Septic OR” to the primary care area of the patient. The patient should be transported wearing a triple-layered medical mask or N95/FFP2 mask.[34],[50],[56] Anti-anxiety doses of benzodiazepines may be administered prior to patient transport. Patients on mechanical ventilation should be transferred with ventilation continued through a Bain's circuit with bacterial and viral filter at the patient end. Use of portable ventilators is not advised in view of their higher aerosol generation property.

   Conduct of Anesthesia Top

Interpersonal communication can be extremely difficult with the PPE donned, hence plan of anesthesia and critical steps need be discussed with the team members. Use of preaccepted sign languages for critical steps is also encouraged.[57] Named PPE gowns make personnel identification easy at this juncture. The surgical procedures that can be conducted under regional/spinal/epidural anesthesia can be conducted under the respective technique as aerosol generation is lesser. However, patient coughing or sneezing in-between the surgery should be prevented as much as possible with adequate sedation. In addition, placing a wet gauze piece in front of the patient's mouth and applying a surgical mask or N95 mask above it can reduce droplet spread. Supplemental oxygen can be delivered with the oxygen mask placed over the surgical/N95 mask.[58],[59] Preemptive use of anti-emetic medications can reduce nausea and vomiting, thereby reducing the infective droplets inside OR. Monitoring leads such as electrocardiography, pulse oximetry, noninvasive blood pressure, and capnography should be single use and disposed off after the procedure.[60]

The World Health Organization surgical safety checklist needs be adhered to while conducting any surgical procedure. At present, there are no validated PPE adherence checklists available. In the interest of safety of doctors and paramedics, it is always prudent to follow an institutional PPE adherence and provider safety checklist intra-operatively [Table 7]. Such checklists aid in the surveillance of effectiveness to PPE adherence and shall be a benchmark in enhancing health-care provider safety.

A vast majority of emergency surgical procedures require general anesthesia (GA). The conduct of GA requires mobilization of multiple machinery and airway aids. Unanticipated complications during GA such as difficult intubation/hemodynamic collapse/cardio-pulmonary arrest require multiple airway aids and resuscitation medications. Mobilizing the entire resuscitation machinery and difficult airway cart into the COVID-19 OR can be labor intensive and further decontamination expensive. We suggest that an experienced anesthesiologist with assistant conduct the procedure in COVID-19 OR, and another trainee anesthesiologist be ready donned in a PPE with advanced instrumentation devices and difficult airway cart in a sterile area adjacent to the COVID-19 OR [Figure 2].

Enhanced preoxygenation with 100% oxygen and a modified rapid sequence induction[61],[62] and subsequent intubation is recommended in COVID-19 patients. Cricoid pressure and gentle positive pressure ventilation, in cases with poor pulmonary reserve, prior to intubation are optional depending on case-to-case basis. GA can be induced with 2–3 mg/kg of intravenous (IV) propofol in hemodynamically stable patients. IV etomidate (0.3–0.4 mg/kg) is preferred for GA induction in patients with cardiovascular comorbidities and hemodynamic instability. IV fentanyl 2–3 μg/kg and IV midazolam 0.01–0.05 mg/kg aid in analgesia and suppressing laryngeal reflexes, respectively. In patients with contraindication to succinyl choline, IV rocuronium is preferred, however the availability of IV suggumadex for rocuronium reversal[63] need be ensured in the unforeseen event of a “cannot ventilate” “cannot intubate” situation.

Use of a video-laryngoscope for intubation should be encouraged for COVID-19 cases[64] as anesthesia provider has restricted mobility with the PPE donned, which can convert otherwise simple procedure difficult. Video-laryngoscope also increase the distance between the patient and the anesthesiologist compared to conventional laryngoscopy, thereby offering protection from macro-droplets. Multiple ancillary methods are suggested for reducing macro-aerosol and droplet generation during laryngoscopy. A water-proof transparent plastic sheet that extensively covers from head to toe of the patient is applied, and the video-laryngoscopy is done below this sheet. This can be used only with video-laryngoscopes that have a separate display screen. One other method is to use a transparent aerosol-box to cover patients head during intubation. The efficacies of such techniques are yet to be ascertained, but those are certainly useful to prevent visible macro-droplets from dispersing.

Endo-tracheal intubation must be contemplated after sufficient depth of anesthesia and neuromuscular blockage so as to avoid any patient “coughing” or “bucking.”[65],[66] Subsequently endotracheal tube cuff must be inflated prior to initiating positive pressure ventilation. Auscultation to confirm bilateral chest air entry to confirm endo-tracheal tube position is difficult with the PPE worn; hence, capnography can be used for confirmation. Most commercially available endo-tracheal tubes have a black marker line one inch proximal to the cuff, the level of which should be at the level of vocal cords after intubation. With the use of video-laryngoscope, the intubating anesthesiologist and his/her assistant can accurately position the endo-tracheal tube to maintain bilateral chest ventilation, thereby avoiding the need for chest auscultation. The anesthesiologist shall remove the outer gloves in a such a way as to wrap the blade of video-laryngoscope with it after confirming endotracheal tube position, following which a new pair of outer gloves can be worn. Total IV maintenance anesthesia or combined use of inhalational anesthetics is at the discretion of the anesthesiologist though adequate depth of anesthesia should be maintained to prevent patient movement.

Lung protective ventilation strategies[67],[68],[69],[70] with target plateau pressure of <30 cmH2O, high PEEP, and low tidal volumes (6 mL/kg) should be used in patients with COVID-19 pneumonitis. In-line suction systems attached to the patient end of ventilator tubing perform better to prevent aerosol generation inside the OR in such cases.

Point-of-care ultrasound (USG) can be used for procedures such as central venous access or regional anesthesia after covering the USG probe and cables with waterproof endoscopy camera covers. Surface decontamination of the device and USG monitor should be done after the surgical procedure. Point-of-care devices such as USG also can be kept with the backup anesthesiologist [Figure 2] donned in PPE ready in the sterile area who shall enter the “COVID-19 OR” only if necessary.

Extubation of cases done under GA shall be done “deep plane” with anti-aspiration and anti-emetic prophylaxis.[64] Medications such as lignocaine IV and dexmedetomidine IV can also be considered to minimize coughing. A two-layered wet gauze placed over the patients mouth and nose without obstructing either can reduce aerosol generation during extubation. Extubated patients should not be “holded” in the postanesthesia care unit and directly transferred to the isolation high dependency unit (HDU). Patients received on mechanical ventilation can be sent to respective isolation ICU for postoperative mechanical ventilation with necessary precautions to reduce aerosol generation as much as possible. It is to be re-iterated that the anesthesia, surgical, and nursing team, who starts the procedure themselves completes it irrespective of change in duty shift timings, to minimize breach in personal protection during such handovers.

   Decontamination after the Surgery Top

After transfer-out of the patient from the OR, the surgical and anesthesia team shall enter the doffing zone to remove the PPE. Doffing can be monitored at a safe distance by an infection control nurse but not assisted to avoid cross-infection. The ideal doffing sequence for PPE is as follows: shoe covers → gloves → hand hygiene → goggles/face shield → hand hygiene → the gown → hand hygiene → the protective mask → hand hygiene → the head cover → hand hygiene → whole-body shower with oral, nasal, and external auditory canal disinfection and change into personal clothing. Medical waste after a case is to be double-bagged and sent for disposal with labeling “COVID-19.”[71]

Disposable monitoring cables should almost always be used in droplet infection scenarios such as COVID-19. Fomites[72] such as writing pen, case records, and mobile phones that can carry the infective virus should be carefully attended to. It is almost always prudent to avoid personal equipment such as mobile phones/pagers/tablets/laptop computers inside the OR. The HME filter, high-quality bacterial/viral filter, reservoir bag, gas sampling tubing, water trap for gas sampling tubing, and the breathing circuits should be discarded after single use.[73]

There are no data testing the efficacy of breathing circuit filters for preventing transmission of SARS COV-2 to the anesthesia machine. A VFE of 99.99% means that only one particle in 10,000 will pass through the filter under standard test conditions that control flow rate (30 L/minute is a commonly used flow for adult condition testing. Increased flow rate reduces the VFE). The best available evidence at present show that the high-quality viral filter prevents the 2019-nCoV from contaminating the anesthesia machine.[74] Moreover, combining the viral filter and HME filter enhances the filtration efficacy. However, during pandemics such as now, it is always advisable that there is a dedicated anesthesia machine for COVID-19 patients.

Manufacturers imply that gas sampled from the machine side of an HME filter is not contaminated. None of the manufacturers at present recommend cleaning procedures that involve the internal components of the anesthesia machine as long as high-quality filters are used with each patient to prevent exhaled 2019-nCoV virus from entering the machine and gas sampling lines are connected to the machine side of the filter. Cleaning internal components of the anesthesia machine is required only if HME, and viral filters were not used during the procedure. Such opening and cleaning of the anesthesia machines are labor intensive, time consuming, and should be done by the manufacturer only.

Reusable equipment, surface of anesthesia machine, video-laryngoscope handles, and floors/walls of the OR should be washed with soap and water followed by surface disinfection with 2%–3% hydrogen peroxide/2–5 g/l chlorine disinfectant/more than 70% alcohol wiping/double concentration sodium hypochlorite (0.1%).[72] Single-concentration sodium hypochlorite and chlorhexidine solutions are infective in inactivation the virus. Respiratory circuit and bacterial/viral filters of the anesthesia machine are to be discarded after single use. The CO2 absorbent should be replaced after each case. The advanced airway aids, difficult airway cart, and resuscitation cart kept ready in the sterile area with the backup anesthesiologist, if unused need not be subject to disinfection had there had not been any contamination.

   Postexposure Prophylaxis to or Professional Top

The surgical team should work together to obtain a concordant entry in all points of the PPE adherence and provider safety checklist used [Table 7]. The signed checklist needs to be retained in hospital records, and an electronic version of the completed checklist should be sent by electronic mail to the hospital infection control facility and COVID-19 committee. Any discordant entry shall be reviewed and will be reassessed to whether to be treated as a breach in personal safety. Incident tracing for accidental lapses in PPE use can be easily facilitated with the PPE Adherence and Provider Safety Checklist. The surgical team member should be psychologically supported and directed in person to the fever clinic for health-care persons of the hospital in case the “COVID-19 committee” deems it to be necessary on retrospective review. The health-care professional shall be provided accommodation in the quarantine facility for staff of the hospital or kept on home isolation. The health-care professional shall be tested for nCoV-19 using throat swab with reverse transcriptase polymerase chain reaction on day 5 and day 14 or early if symptomatic.

The present practice advisory by the National Task Force for COVID-19 of the Indian Council of Medical Research advises a postexposure prophylaxis with tablet hydroxychloroquine 400 mg (HCQ) twice a day on day 1 followed by 400 mg once weekly for next 7 weeks.[50] The drug is contraindicated in persons with retinopathy and allergy to 4-aminoquinone compounds. However, evidence of efficacy of this medication in prophylaxis is still in its infancy,[75],[76],[77] and such intake shall not instill a false sense of security against the disease. Besides this, the health-care worker shall be given an opportunity to participate in the randomized controlled trial on the role of HCQ in postexposure prophylaxis on an informed consent basis. Antiviral drugs such as remdesivir, lopinavir, ritonavir, oseltamivir, and tocilizumab are used for only for the treatment of COVID-19 cases[78],[79],[80],[81],[82],[83] and not indicated for postexposure prophylaxis.

   Conclusion Top

The COVID-19 as a pandemic emerged as a global threat all too suddenly that governments world over have found it unmanageable or difficult to contain. Disease severity shows variation depending on demographic characteristics such as age; history of chronic illnesses such as cardiovascular/renal/respiratory disease; pregnancy; immune-suppression; angiotensin-converting enzyme inhibitor medication use;[84] and nonsteroidal anti-inflammatory drug use, but the pattern of disease spread is uniform – contact, droplets, and fomites. Absence of an effective treatment or vaccine[85] is a major setback to contain the disease. As such, social distancing and hand hygiene are the norms to prevent transmission. Isolation of affected or suspected cases is the prevailing means of controlling spread. Considering that a case of COVID-19 can anytime require emergency surgery for lifesaving reasons and such a requirement is directly proportional to the number of cases in the community, it is imperative to design, develop, and adhere to precautionary outlines suggested here to keep the anesthetic and para-medical support staff away from chances of getting infected by this deadly virus.
