The cerebrovascular Doppler examination (CDE) and oculopneumoplethysmography (OPG-Gee) were compared in a single population group with no statistically significant difference found between the 2 studies. There appeared to be an advantage to combinant testing, for when the results of the 2 studies were concordant there was an accuracy of 94% and a false negative rate of 8%. Clinical correlation was available in 96% of the patients, providing adequate evidence to support the adjuvant role of non-invasive screening in the evaluation of symptomatic individuals. The percentage of false negative studies and the incidence of ulcerative disease make a diagnostic role impractical at present. For the asymptomatic individual, the diagnostic role of non-invasive screening seems justified. The false negative studies in the present series were confined to those vessels with 50-70% stenoses, which are difficult to assess angiographically and may be better characterized by hemodynamic evaluations.

Teaching effectiveness: evaluation of computer-assisted instruction for cardiopulmonary resuscitation.

Computer instruction for cardiopulmonary resuscitation (CPR), using a case-simulation program, was evaluated for its teaching effectiveness. First-month anesthesia residents, divided into two groups, A and B, underwent a cognitive evaluation on their 1st day of arrival and again on their 5th day. Both groups were provided with clear educational objectives and reading materials, a tutor was assigned to each student to answer specific questions. Students in group A, also given computer-assisted instruction (CAI), showed a significantly higher learning than those in group B, who served as controls. That CAI was a highly motivational form of learning was established by later voluntary participation in CAI of all group B students.

Preoperative mini-heparin, prostatectomy and clinical pulmonary thromboembolism.

From February 1973 through May 1977, a selected group of 131 patients undergoing prostatectomy were given preoperative mini-heparin 6--8 hours prior to surgery. There were 17 retropubic prostatectomies, 1 subtotal suprapubic prostatectomy and 113 transurethral prostatic resections. Patients ages ranged from 35 to 108 years. There were 109 cases of benign prostatic hyperplasia, 13 cases of adenocarcinoma of the prostate and 9 cases of benign prostatic hyperplasia with foci of adenocarcinoma. There was one death from massive pulmonary thromboembolism and one case of non-fatal pulmonary thromboembolism. A retrospective review of 416 prostatectomies performed during the same period of time at the same hospital, in which mini-heparin was not administered preoperatively, revealed only one case of non-fatal pulmonary thromboembolism. Our study indicates that this preoperative mini-heparin regime did not effectively reduce the morbidity and mortality associated with clinical postoperative thromboembolic phenomena. There were no important side effects, such as prolonged bleeding or drug intolerance, associated with the administration of preoperative mini-heparin.
