Description: Segment 1 An elderly male patient sits in bed coughing. The narrator explains a common complication of anaesthesia (due to repressed respiration) is that secretions gather in the patients' lungs. A method of inserting a catheter into the back of a female patient is shown so that continual analgesia can be dispensed to the same site without causing infection this was developed in Oxford. Diagrams show how the needle reaches the extradural space, thereby blocking pain to the mid-torso.

After administering analgesia, Duncaine, he is considerably chirpier, sitting up and chatting to the nurse. He is allowed to get out of bed, paces up and down and swings his arms above his head whilst holding his intravenous drip.

He performs sit-ups in bed to demonstrate the lack of pain. After this moderate exercise, although not shown on camera, it is noted that the patients' blood pressure is checked. Another patient, described as a red-headed labourer, also benefits from analgesia given after a partial gastrectomy this sequence follows the same pattern before and after pain relief.. Time start: 00:07:43:10 Time end: 00:11:21:00 Length: 00:03:38:15 Segment 4 A woman of 41 is shown post-operatively she is in pain and her respiration is depressed but after receiving Duncaine she is described as co-operating fully by breathing deeply and coughing. Finally she falls asleep. Time start: 00:11:21:00 Time end: 00:14:06:21 Length: 00:02:45:21
