[Stability of personality in later life].

The relation of aging and the stability of personality in late life is evaluated by a literature review. The findings of six longitudinal studies reveal that rank-order consistency continues into old age. The mean-level stability reveals a concave curve for 'neuroticism' with an increase after age 80, a decrease for 'extraversion', and an increase for 'agreeableness'. The methodological and conceptual issues of personality assessment with old adults can be resolved by using a self report scale which corresponds to the capacities and the lifestyle of older adults and by involving age related variables into analyses.

Clinical effect of Bretschneider-HTK and St. Thomas cardioplegia on hemodynamic performance after bypass measured using an automatic datalogging database system.

A prospective consecutive study was undertaken to compare the hemodynamic effect of two cardioplegic solutions in CABG patients after bypass, and in relation to aorta occlusion time with the support of a automatic datalogging database. A total of 249 patients were randomized. One group received Bretschneider cardioplegic HTK solution (132 patients, group I) the other group received St. Thomas cardioplegic solution (117 patients, group II). The data was divided in four periods of aortic clamp time: less than or equal to 40 min (group I 26 patients, group II 32 patients); 41-60 min (group I 49 patients, group II 47 patients); 61-80 min (group I 30 patients, group II 29 patients); and greater than 80 minutes (group I 27 pts, group II 9 patients). Anesthesia regime and therapeutic drugs and infusions were given in both groups in similar dosages. Within both groups HR, CO, PAP, PCWP increased after bypass in relation to prebypass values. SVR decreased in both groups by 30%, MAP and PVR decreased only in group I. Between group I and II differences were found in the CI (3.0 vs. 3.3 l/min/m2), MAP (70 vs. 76 mmHg), PMAR (18 vs. 16 mHg), and SVR (827 vs. 954 dyn.sec.cm-5). In significantly more of the patients in group I, sinus rhythm started spontaneously after the release of the aorta clamp (39.5% vs. 20.4%, p less than 0.005). Patients in group I needed temporarily a pacemaker after bypass in 6.3% cases (in 1.1% of patients in group II,). There was no relation of the hemodynamic data in relation to aorta occlusion time within the groups.(ABSTRACT TRUNCATED AT 250 WORDS)

[Experiences with an anesthesia protocol written by computer].

Since December 1983, we have used a computer system for charting and data logging in cardiac and thoracic anesthesia. These computers, designed as stand-alone units, were developed at our hospital based on Motorola 6809 microprocessor systems. All measurements derived from anesthetic monitoring, ventilator, and heart-lung machine are automatically sampled at regular intervals and stored for later data management. Laboratory results are automatically received from the hospital computer system. The user communicates with the system via a terminal and a keyboard; this also facilitates the entering of all comments, medications, infusions, and fluid losses. All data are continuously displayed on an A3 format anesthetic chart using a multi-pen, flat-bed plotter. The operation of the system has proved to be simple and needs less time than charting by hand, while the result, the display on the chart, is far clearer and more complete than any handwritten document. Up to now 3,200 operations (corresponding to 12,500 anesthetic h) have been documented. The failure rate of the system, defined as an interruption of the documentation for more than 30 min is 2.1%. Further development of the system is discussed. A data base for processing the stored data has been developed and is being tested at present.

Controlled administration of oxygen with self inflating resuscitation bags.

Resuscitation bags were originally developed to ventilate patients under emergency conditions. Under circumstances where oxygen is available one should make full use of it. The problem of exact air enrichment for these bags has not been satisfactory solved until now. Therefore a system has been developed which furnishes controlled delivery of FIO2 during ventilation with self inflating resuscitation bags. This is obtained via a venturi device connected to the air inlet of the manual resuscitation bag. The FIO2 delivered to the patients from a self inflating bag was tested for values of 24, 30, 40 and 50% oxygen. The new system proved to be capable to delivery exact FIO2 in contrast with previously applied methods of oxygen delivery where this could never be achieved.
