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)
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)
The anatomic and clinical features of 47 patients who were 18 years of age or older at the time of total intracardiac repair for tetralogy of Fallot are reviewed. Twenty (43%) patients had had previous palliative surgery. Of 14 pulmonary-systemic shunts, 9 (64%) remained patent. The location of the ventricular septal defect was infracristal in 90% of… (More)
