Nerve Impulse Conduction
It is essential that perioperative practitioners have an understanding of nerve conduction, as many drugs used in the operating theatre have an impact on the nervous system and nerve conduction. The most obvious, but not the only one, being local anaesthetics which prevent pain and other nerve signals reaching the brain, by temporarily blocking nerve conduction.
This module examines how nerve cells communicate by sending signals to each other and various other tissues throughout the body. It is a simplified explanation of a complex topic.
Length of Study: 60 min.
General anaesthesia in obstetrics
Major advances in obstetric anesthesia have resulted in improved maternal outcomes but the failure rate is still higher than in non-obstetric anaesthetics. The consequences of a failed intubation in the obstetric patient may not only affect the mother, but also the fetus. This article gives an overview of how to conduct a GA in obstetrics safely and safely manage a failed intubation to ensure a good outcome. It contains guidance to the OAA/DAS Obstetric Airway Guidelines.
Bronchospasm during general anaesthesia
Bronchospasm is a relatively common event during general anaesthesia. Anaesthetic assistants need to know how to identify and treat bronchospasm. Management begins with switching to 100% oxygen and calling for help early. Increasing the inspired concentration of Isoflurane and Sevoflurane will produce bronchodilatation and is a good start.
An Introduction to Paracetamol
Paracetamol is a commonly used medicine that can help treat pain and reduce a high temperature. In normal doses it is considered safer than many analgesics as it has no effect on the cardiovascular and respiratory systems and unlike Non-steroidal anti-inflammatory drugs (NSAIDs) it does not cause gastric irritation or bleeding.
One caution, especially for the perioperative environment, is that as IV paracetamol has close to 100% bioavailability and IV doses must be adjusted in low weight individuals to prevent overdose.
Nonsteroidal anti-inflammatory drugs (NSAIDs)
Nonsteroidal anti-inflammatory drugs (NSAIDs) are medications that relieve or reduce pain. Their actions are analgesic, anti-inflammatory and antipyretic.
Perioperatively, using NSAIDs avoids many of the adverse effects of opioids such as respiratory depression, sedation, nausea and vomiting and gastrointestinal stasis. Although an effective analgesic they have significant adverse effects and contraindications which the perioperative practitioner must be aware of.
An introduction to the autonomic nervous system
As many procedures and drugs used in anaesthetic practice have a direct influence on the autonomic nervous system, it is essential that the anaesthetic assistant should have an understanding of its structure and function although this is a very simplified introduction of a large and complex topic.
Anaesthetics for obese patients
The prevalence of obesity has tripled over the past 40 yrs and there are now more than 650 million obese adults worldwide. This article offers an update of the perioperative risk and the associated morbidity that obesity causes and its impact on anaesthetic management.
Safe tracheal extubation
This article covers complications occurring during emergence, extubation and later in recovery. It details the DAS guidelines on safe extubation and explains the factors that increase the risks of
adverse events. It also describes how to optimise conditions before tracheal extubation.
Understanding the circle system
Although the circle system looks relatively simple, it is a deceptively complex arrangement that needs to be fully understood to use safely, especially at low flows.
This module explains the components, setup and both advantages and disadvantages of the circle system.
Metal Max COMBI 50 Disposable Laryngoscope Blade & Handle (sponsored)
The Combi is a one piece system with Blade and Handle fixed together allowing Test in the Bag functionality testing prior to use. It is based on a Conventional system with meLED™ (metal enclosed) LED on the blade powered by a preloaded 6V battery handle giving excellent light output when and where it is required.
The respiratory system – The process of respiration
This module covers the physiological process of respiration, of which breathing is only the first stage. The ultimate function of the respiratory system is gas exchange which consists of supplying the body’s tissues with oxygen and removing carbon dioxide, the waste product.
There are three key elements to this process; pulmonary ventilation, external respiration, and internal respiration.
Length of Study: 60 min.
Malignant hyperthermia (MH) is a rare life-threatening condition that is usually triggered by exposure to certain drugs used for general anesthesia. This module reviews malignant hyperthermia, its clinical features and presentations as well as its management during an MH crisis.
This module is largely based on the ‘Malignant hyperthermia 2020 Guidelines’ from the Association of Anaesthetists.
Direct vision laryngoscopes
Laryngoscopes are used to aid tracheal intubation and the placement of endotracheal tubes. They allow visualisation of the larynx and are used not only in operating theatres but ITU and A&E. They can also be used to visualise the larynx for suctioning, removal of a foreign body and placing nasogastric tubes and throat packs.
This module covers conventional or direct laryngoscopes. Video laryngoscopes and fibreoptic intubation are covered in different modules.
Length of Study: 45 min.
Anaesthetic machines back to front
The most important piece of equipment that the anaesthetist uses is the anaesthesia machine. The basic function of an anaesthesia machine is to prepare a gas mixture of precisely known, but variable composition. The gas mixture can then be delivered to a breathing system. The anaesthesic machine itself has evolved from a simple pneumatic device to a complex array of mechanical, electrical and computer–controlled components. This module breaks down the essential features of the anaesthetic machine into its parts, explaining their purpose as it goes.
Length of Study: 45 min.
Understanding Central Venous Lines
This module discusses various types of central lines and central venous catheters (CVC). They are often needed in critically ill patients or in those requiring prolonged intravenous therapies that cannot be given orally or through peripheral lines.
Getting the best out of videolaryngoscopy
The benefits of videolaryngoscopy, especially in unexpected difficult intubations, are numerous but they are not just conventional laryngoscopes with screens. Many have different techniques and need specific training. This module gives tips on how it to use it to its best advantage.
Nonin 9590 Onyx Vantage Finger Pulse Oximeter – Proact (sponsored)
When you need to make decisions quickly, you do not have time to question the accuracy of your finger pulse oximeter. You can trust Nonin Medical’s Onyx® Vantage finger pulse oximeter with PureSAT® technology to quickly and accurately capture SpO2 and pulse rate measurements — even on patients where motion and low perfusion are a challenge. In fact, Onyx is the only finger pulse oximeter brand whose accuracy and performance claims are supported by published peer-reviewed, clinical studies.
Muscle Relaxants; reversal and the use of peripheral nerve stimulators.
This module discusses residual block, why, when and how muscle relaxants are reversed, and the importance of using a peripheral nerve stimulator when assessing the depth of block. It also covers the different patterns the stimulators use to assess how deep a neuromuscular block is.
Emergency front of neck access in airway management
This module describes the guidance for emergency front of neck access, reviews techniques to improve decision making in the transition to eFONA and reviews the ‘scapel, bougie,
tube’ technique when performing eFONA.
