STUDY OBJECTIVES To compare the effects of four techniques for preventing or blunting the hypertensive response to the insertion of Mayfield headrest skull pins: intravenous (IV) alfentanil (ALF), esmolol (ESM), thiopental sodium (TPL), and local anesthesia using plain lidocaine (Xylocaine; XYL). DESIGN Randomized open study. PATIENTS 40 adult patients(More)
With improvements in the surgical technique for orthotopic liver transplantation, patients with significant underlying systemic disease are considered candidates for transplantation, thus increasing the complexity of the medical management of these patients and necessitating additional monitoring in order to minimize the anesthetic risk. We describe the(More)
Five cases of spontaneous pneumothorax were treated with video-assisted thoracoscopic surgery (VATS). These included four cases of recurrent pneumothorax and one case of persistent pneumothorax. The mean age was 33 years. The identified bullae were eliminated with either endoloop ligation (in one patient) or stapled excision (in four patients). There were(More)
This study examines the effects of acute hypocapnia, instituted prior to reperfusion of the graft liver, on the middle cerebral artery (MCA) Doppler blood flow velocity response to reperfusion during orthotopic liver transplantation in humans. Seventeen patients with chronic liver disease underwent continuous, noninvasive Doppler imaging of the MCA.(More)
This case demonstrates the use of brainstem auditory evoked potentials (BAEPs) to monitor cranial nerve function. Changes in BAEPs were associated with cranial nerve dysfunction in the trigeminal nerve on the ipsilateral side and the facial nerve on the contralateral side.
Serum human placental lactogen (HPL) levels in forty cases of intact hydatidiform mole were measured by radioimmunoassay. The HPL values were generally lower than normal pregnancies of the corresponding period of gestation. However, normal and occasionally higher than normal values were observed in a few cases. Serum HPL level alone is of some clinical use(More)
A 24-year-old man who was initially thought to have nocardiosis of his mediastinal lymph node which progressed to involve his right lung, had to undergo a right pneumonectomy when he failed to respond to treatment with sulphadiazine. Histology of the right lung specimen and a subsequent axillary lymph node biopsy revealed that he actually had(More)
