Description: Segment 1 The first sequence on this film starts with a female patient in bed. A bottle of paraldehyde is presented to the viewer. It is unstoppered and a needle is charged with the liquid. The female patient is injected with the preparation. A clock demonstrates the speed of anaesthesia (the patient coughs a few times before she is fully unconscious). Time start: 00:00:00:00 Time end: 00:01:17:11 Length: 00:01:17:11 Segment 2 The second sequence shows an elderly male patient (he appears to have no teeth) with an anaesthetic mask. Preparation for intubation is shown, then a tube is inserted down his throat. The next sequence shows a human pathological specimen a cross section of the head and throat region. Sequences are repeated showing how the patient is intubated. This material is repeated several times with one OK slate in between suggesting that these are rushes (some shots are out-of-focus). An anaesthetic mouth piece is presented to camera. Time start: 00:01:17:11 Time end: 00:06:12:20 Length: 00:04:55:09 Segment 3 A female patient is then intubated nasally. Time start: 00:06:12:20 Time end: 00:07:02:05 Length: 00:00:49:10
