Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of acceleromyography and electromyography in vecuronium-induced neuromuscular blockade with xenon or sevoflurane anesthesia.
To compare acceleromyography (AMG) and electromyography (EMG) with xenon or sevoflurane anesthesia during vecuronium-induced neuromuscular blockade. ⋯ AMG and EMG-cannot be used interchangeably with either xenon or sevoflurane anesthesia.

Carbon dioxide dynamics during apneic oxygenation: the effects of preceding hypocapnia.
To compare the rate of increase of arterial carbon dioxide tension (PaCO2) during apneic oxygenation preceded by acute respiratory hypocapnia with that during apnea preceded by respiratory eucapnia. ⋯ Acute hypocapnia compared with eucapnia prior to apneic oxygenation is associated with a greater rise in PaCO2 in the anesthetized patient. This finding may be due in part to widening of the venoarterial gradient of pCO2.

Evaluation of anxiolysis and pain associated with combined peri- and retrobulbar eye block for cataract surgery.
To evaluate five different preoperative anxiolytic regimens in cataract surgery performed under regional anesthesia; to quantify the pain associated with combined peri- and retrobulbar injection (PRBI) of local anesthetic drugs; and to describe a technique of painless eye block. ⋯ 1. There was interpersonal variation in the level of preoperative anxiety. 2. In patients who were anxious, the anxiolytic drugs and placebo decreasedanxiety although the level of anxiety did not differ between the anxiolytic drugs or between placebo and the anxiolytic drugs. The only difference was in Group 1 patients (3 mg promazepam), who reported slightly increased anxiety before and during PRBB administration (p < 0.05). 3. Placement of the PRBB is less painful than the insertion of a 20 g i.v. cannula.

We present a case report of a patient who developed an unusual bilateral breast pain syndrome after a reduction mammoplasty. Her symptoms and physical examination findings resolved after four stellate ganglion blocks, of which two on each side were performed over a period of 2 weeks. The case serves to alert clinicians to the possibility of a patient developing a sympathetically mediated pain syndrome after reduction mammoplasty.
