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.
Length of Study: 120 min.
Difficulty: Medium
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.
Length of Study: 120 min.
Difficulty: Medium
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.
Length of Study: 60 min.
Difficulty: Medium
Inadvertent perioperative hypothermia can occur in up to 40% of surgical patients so it essential for theatre practitioners to know what causes it and how to prevent it.
A well as being very stressful and uncomfortable for patients upon waking, it has many negative consequences including delayed drug metabolism, wound healing and increased infection rates.
Length of Study: 75 min.
Difficulty: Easy
This module explains the basic principles of capnography, discusses EtCO2 waveforms, and how to interpret them in the ventilated patient.
Length of Study: 60 min.
Difficulty: Medium
BIS or Bispectral monitoring is a relatively new but controversial technology to monitor depth of anaesthesia. This module covers how it works and if it works.
Length of Study: 60 min.

This module covers the safety features built into the modern anaesthetic machine. With more theatres moving to electronic self-checking machines this is a useful reminder of where we have come from and how safety is built into all aspects of the anaesthetic machine. It is also useful for anyone new to anaesthetics.

Awareness during anaesthesia can be very distressing for a patient, particularly if accompanied by recall of the painful nature of surgery. This article explores the types, incidence, consequences, causes, management and avoidance of intraoperative awareness.
Length of Study: 60 min
Difficulty: Easy
This module covers the basic principles behind setting up, inserting and monitoring intra-arterial blood pressure lines that an anaesthetic assistant needs.
There is also an separate advanced module available which covers more of the physics indepth.
Length of Study: 90 min
Difficulty: Easy
Intra-arterial blood pressure measurement is often considered to be the gold standard of blood pressure measurement. This accuracy however, depends on a number of physical principles of the systems used, which are explored in this advanced module.
The is also a separate easier module available covering setting up and using arterial lines.
Length of Study: 75 min

Health professionals use the electrocardiograph (ECG) rhythm strip to systematically analyse the cardiac rhythm. Before the systematic process of ECG analysis is described it is important to understand the individual waveforms, segments and intervals of the ECG. This module reviews all these steps.
Length of Study: 90 min

The pulse oximeter provides an indication of oxygen status in the body. However, the link between a pulse oximeter reading and the events occurring in the body can be complex and difficult to evaluate. We all require an understanding of factors associated with oxygen uptake and delivery to be able to use pulse oximetry in a knowledgeable way.
