Comparative Study
The oesophageal obturator airway: A study of cadaver lund ventilation through obturator airways and tracheal tubes.
Ventilation of cadaver lungs using a Pneupac ventilator through oesophageal obturator airways (EOA), oesophageal gastric tube airways (EGTA), and tracheal tubes was studied in 23 subjects. The mean tidal volume obtained through tracheal tubes was 381 ml compared with a mean tidal volume of 156 ml obtained through the EOA and a mean tidal volume of 237 ml through the EGTA. ⋯ This represents adequate ventilation in these very stiff lungs. Subject to modification of the device and prevention of leakage the oesophageal gastric tube airway is a useful alternative to tracheal intubation in certain adverse conditions.

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.
