Intubation training on a manikin (Doctors from Department of Anaesthesiology).

The Department of Anaesthesiology at the University of the Free State, in collaboration with the Clinical Simulation and Skills Unit, has trained almost 500 hospital staff members dealing with the Covid-19 pandemic since the lockdown started.

The unit assisted doctors, nurses, and staff working at the Universitas and Pelonomi hospitals with training in the use of personal protective equipment (PPE), including protective clothing, masks, gloves, aprons, and eye protection. The training started the week of 16 March and was led by Prof Gillian Lamacraft, Head of the Pain Control Unit in the Department of Anaesthesiology, and registrars in the Department of Anaesthesiology. Training was not only limited to healthcare workers in hospital wards designated for COVID-19-positive or suspected COVID-19 patients, but workers throughout the hospital received training, lest they be required to care for COVID-19-positive patients in the future, especially if there is an increase in the cases being treated in the hospital.

Training members of the anaesthesia department
According to Prof Lamacraft, the training was initially started to ensure that members of the anaesthesia department would be protected if the need arose for them to wear PPE while treating a COVID-19 patient. Members of the anaesthesia department are not routinely involved in the medical care of patients with serious infectious disease (e.g. Ebola virus), and because they were not previously required to wear PPE regularly, they are not familiar with its use. 
“Internationally, the healthcare workers most exposed to the virus appear to be the ones most at risk of dying, presumably owing to the greater viral load they receive. COVID-19 patients who are severely ill, may require intubation so they can be ventilated – this procedure puts the doctor performing it very close to the airway of the patient, and greatly at risk of being contaminated with COVID 19 during this procedure.” 

“Failure to intubate the patient successfully can lead to the rapid demise of the patient, so it has been decided as hospital policy that anaesthetists will preferably be the doctors performing these intubations, if they are available, as they are considered the doctors best at this procedure. Therefore, anaesthetists will be a group of doctors in the hospital at great risk of COVID virus exposure,” says Prof Lamacraft.

Training other healthcare workers
To facilitate this training, registrars in the Department of Anaesthesiology made videos to demonstrate the donning (putting on) and doffing (taking off) procedure for PPE. Members of the Universitas Academic Hospital’s Infection Control Team provided them with the required information and assessed the training videos for correctness.

The department used the Clinical Simulation and Skills Unit’s facilities at the university to conduct this training, so that the participants could also physically practise putting on and taking off the PPE after watching the videos. 

“Since then, we have been doing this training every working day. Having trained our department, the members of the COVID-19 task team for the Universitas Hospital asked us to train other healthcare workers at the hospital. Accordingly, we have trained many other healthcare workers (over 430 for PPE training alone), including heads of department, professors of medicine, specialists, registrars, medical officers, interns, all ranks of nursing staff, clinical technologists, and household aids.”

The different types of PPE
Prof Lamacraft says it is important that all these healthcare workers are taught the different types of PPE (i.e. standard and aerosol-generating procedure PPE (AGP PPE). In particular, they had to understand that a special type of mask, an N95 mask, should only be used for AGP PPE, as these are in extremely short supply internationally. 

“Many healthcare workers did not know how to put these on correctly, or which size to wear – this had the potential for wastage of this precious commodity. Taking off PPE contaminated with the COVID-19 virus is a very risky procedure. Failure to do so correctly, can lead to not only the healthcare worker contaminating themselves (e.g. by touching their eyes or face while taking off their masks), but also to the contamination of the healthcare workers assisting the person in taking off their PPE; or even to the participant taking home the virus on their bodies and contaminating their family at home. Therefore, the healthcare workers had to be shown how to take off their PPE without contaminating themselves.”
In order to reduce the risk of trainers and other participants being infected during training by healthcare workers who are asymptomatic carriers of COVID-19, only two to four participants have been trained at a time and strict rules were kept regarding social distancing and the use of hand sanitiser.

The training is essential to protect healthcare workers
Prof Mathys Labuschagne, Head: Clinical Simulation and Skills Unit, says volunteering doctors and nurses are also trained to work in ICUs with COVID-19 patients. The ICU department trained these volunteers in the use of ventilators, to assist with putting up drips and lines, intubation, and PPE. The goal is to train healthcare providers to assist in ICU when needed. 

“This training is essential to train and prepare healthcare workers when the patient numbers are increasing. The training is also essential to protect the healthcare workers against infection, because we need them to stay healthy to be able to manage the patients,” according to Prof Labuschagne.

Dr Edwin Turton from the Department of Anaesthesiology says the training is for frontline healthcare workers (nurses, cleaners, porters, doctors, and even washers from theatre) who need to protect themselves in order to protect their patients and all other staff helping them to care for the patients.

“Doctors and nurses need different forms or levels of PPE for working in the clinical environment, and we need them to train to wear appropriate PPE for AGP and contact with PUI and positive patients. They need to be able to protect themselves. The training is for all healthcare workers and not only for doctors and nurses,” says Dr Turton.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
