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.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
