Comparison of topical lignocaine gel and fentanyl for perioperative analgesia in children undergoing cataract surgery.

28 Dec 2009 BACKGROUND: Opioids continue to remain the primary analgesics in children undergoing ophthalmic surgery, and their use may be associated with adverse effects like vomiting and respiratory depression. Topical anesthesia avoids these adverse effects ... Read more...

The relationship of bipolar left ventricular pacing stimulus intensity to cardiac depolarization and repolarization in humans with cardiac resynchronization devices.

13 Dec 2009 BACKGROUND: Myocardial depolarization can be altered by varying pacing stimulus output. This may have implications on response rates for cardiac resynchronization therapy (CRT). The purpose of our study was to determine the relationship of left ... Read more...

Doctors' stress responses and poor communication performance in simulated bad-news consultations.

30 Oct 2009 PURPOSE: No studies have previously evaluated factors associated with high stress levels and poor communication performance in breaking bad news (BBN) consultations. This study determined factors that were most strongly related to doctors' stress ... Read more...
