Comparative Study
Postoperative analgesia for day-case herniorrhaphy patients. A comparison of cryoanalgesia, paravertebral blockade and oral analgesia.
Patients were admitted as day-cases for inguinal herniorrhaphy under epidural anaesthesia and chlormethiazole sedation. The patients were given oral analgesia, and in addition, some were given either a paravertebral block with a dextran/bupivacaine mixture or cryoanalgesia of the ilio-inguinal nerve for postoperative pain relief. These anaesthetic and analgesic techniques are discussed in relation to day-case herniorrhaphy.

The general relationships between the pressure inside an endotracheal tube cuff, the pressure exerted by that cuff on the tracheal wall and the airway pressure have been re-examined in a model system. In relatively recent literature, the tracheal wall pressure at a given cuff volume has been calculated as the difference between intracuff pressures at that volume when the cuff is inflated inside the trachea and when it is inflated whilst suspended freely in air. This has been used as a general relationship, as an alternative to direct measurement in real and model tracheas. In this study, the directly measured pressure was not generally equal to the pressure as calculated above.
