Alfentanil in low dosage (8 μg kg−1) as an analgesic agent for short duration surgery was evaluated. Forty-one women undergoing laparoscopy received double-blind either alfentanil 8 μg kg−1 or normal saline at induction, and all received thiopentone, alcuronium, enflurane, nitrous oxide and oxygen. The fall in mean arterial pressure (MAP) with induction was similar between groups. The MAP following intubation with alfentanil was unchanged, while with normal saline a mean rise of 23 (SD 15.2) mmHg occurred (P<0.001). The pulse rate following intubation showed a smaller rise (P<0.001) with alfentanil of 26 (SD 14.6) beats min−1, than the normal saline group of 46 (SD 13.3) beats min−1. Alfentanil was found to be a safe and effective analgesic agent in short duration surgery, by reducing sympathetic responses to intubation without cardiovascular depression or compromise of postoperative recovery.

Abstract. In the current study, we examined the viability of a multidimensional conception of perceived person-environment (P-E) fit in higher education. We introduce an optimized 12-item measure that distinguishes between four content dimensions of perceived P-E fit: interest-contents (I-C) fit, needs-supplies (N-S) fit, demands-abilities (D-A) fit, and values-culture (V-C) fit. The central aim of our study was to examine whether the relationships between different P-E fit dimensions and educational outcomes can be accounted for by a higher-order factor that captures the shared features of the four fit dimensions. Relying on a large sample of university students in Germany, we found that students distinguish between the proposed fit dimensions. The respective first-order factors shared a substantial proportion of variance and conformed to a higher-order factor model. Using a newly developed factor extension procedure, we found that the relationships between the first-order factors and most outcomes were not fully accounted for by the higher-order factor. Rather, with the exception of V-C fit, all specific P-E fit factors that represent the first-order factors’ unique variance showed reliable and theoretically plausible relationships with different outcomes. These findings support the viability of a multidimensional conceptualization of P-E fit and the validity of our adapted instrument.
