A feline anaesthetic death associated with equipment incompatibility
1Jurox Pty Ltd, 85 Gardiner Street, Rutherford, New South Wales, 2320, Australia.
Background:
A juvenile cat was anaesthetised for ovariohysterectomy. After intubation, the endotracheal tube was connected to an end-tidal CO2 (ETCO2) in-line adapter and then to a non-rebreathing anaesthetic system. Immediately on connection to the non-rebreathing system, the patient developed abdominal distension. The endotracheal tube was removed and found to be supplying a continuous flow of oxygen while connected to the ETCO2 monitor adapter and rebreathing system. The adapter was removed from the rebreathing line and the endotracheal tube re-inserted. Despite resuscitation attempts, the cat died.
Results:
Necropsy revealed barotrauma to the lungs and separation of the diaphragm from the dorsal body wall, with retroperitoneal gas accumulation. Close inspection of the gas delivery system revealed the creation of a plastic-to-plastic seal between the internal fresh gas pipe of the non-rebreathing system and the ETCO2 adapter, preventing overflow of excess gas.
Conclusion:
Careful assessment of equipment compatibility before every anaesthetic event is essential.

Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
01:30Equipments Used To Measure Blood Pressure
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
