Endotracheal tube cuff pressure monitoring and control (Musa Muallem, 19 January 2011)
Dear Editor
I do agree fully with the authers of this article that mandatory monitoring of the ET tube cuff pressure is needed.In my experience in this field of fifty years I likewise found that the ET tube cuff pressure exceeded 30 cm of water in about 50% of cases especially if the operation lated over two hours. Anesthesiologist continue to ignore the above important recommendation in many istitutions because they do not have easy access to devices that monitor and control cuff pressure. Intermittant checking of the cuff pressure during anesthesia is not good enough and has a very poor compliance. The cuff pressure should be monitored and controlled at the required level continouessly and automatically without the anesthesiologist having to worry about it. This situation...

why only dental or renal pain (medha joshi, 12 May 2010)
this is very interesting . if pressure is relieving dental pain then any chronic pain should be relieved. has there been any research in this direction? what made you chose patients only with dental or renal pain? why not migraine.

Causes of local resistance. (Adrian Woollard, 18 June 2007)
Dear AuthorsI thought your article was well written. We have recently had a similar case of local anaesthetic resistance. It was a patient presenting as an emergency for a caesarean section. The patient had a history of failure of local anaesthetics for dental procedures and dermatological procedures. The spinal also failed despite good practice. We never found a reason for it to fail. Other reasons we suspect would include subarchnoid cysts which although rare in the lumbar regional could explain the aspiration of CSF and the ability to inject 2 mls without detectable resistance. A review article in the BJA could explain where a mutation in the channel would cause resistance to local anaesthetics. It would be interesting to find the incidence of failure to produce a spinal despite the...
