Somatosensory Evoked Potentials suppression due to remifentanil during spinal operations; a prospective clinical study

<p>Abstract</p> <p>Background</p> <p>Somatosensory evoked potentials (SSEP) are being used for the investigation and monitoring of the integrity of neural pathways during surgical procedures. Intraoperative neurophysiologic monitoring is affected by the type of anesthetic agents. Remifentanil is supposed to produce minimal or no changes in SSEP amplitude and latency. This study aims to investigate whether high doses of remifentanil influence the SSEP during spinal surgery under total intravenous anesthesia.</p> <p>Methods</p> <p>Ten patients underwent spinal surgery. Anesthesia was induced with propofol (2 mg/Kg), fentanyl (2 mcg/Kg) and a single dose of cis-atracurium (0.15 mg/Kg), followed by infusion of 0.8 mcg/kg/min of remifentanil and propofol (30-50 mcg/kg/min). The depth of anesthesia was monitored by Bispectral Index (BIS) and an adequate level (40-50) of anesthesia was maintained. Somatosensory evoked potentials (SSEPs) were recorded intraoperatively from the tibial nerve (P37) 15 min before initiation of remifentanil infusion. Data were analysed over that period.</p> <p>Results</p> <p>Remifentanil induced prolongation of the tibial SSEP latency which however was not significant (p > 0.05). The suppression of the amplitude was significant (p < 0.001), varying from 20-80% with this decrease being time related.</p> <p>Conclusion</p> <p>Remifentanil in high doses induces significant changes in SSEP components that should be taken under consideration during intraoperative neuromonitoring.</p

The exonerating effect of sexual objectification: Sexual objectification decreases rapist blame in a stranger rape context

A blossoming body of research documents the effect of sexual objectification on social perception, but little is known about the consequences of sexual objectification. This paper examines how sexual objectification influences men and women’s rape perception in case of a stranger rape. Given that people attribute the full responsibility to the rapist in case of stranger (vs. acquaintance) rape, situational factors are more likely to shift attribution of rapist blame in cases of stranger rape. We hypothesized that victim’s sexual objectification might diminish rapist blame and increase victim blame in case of a stranger rape. Fifty-eight male and fifty-seven female Belgian undergraduate students were assigned to either a sexual objectifying (i.e. body focus) or to a personalized portrayal (i.e. face focus) of a rape victim. After reading a newspaper report depicting a stranger rape, participants were asked to evaluate the extent to which they blamed the rapist and the victim. As predicted, participants blamed the rapist less in the sexual objectification condition, regardless of participant gender. In contrast, sexual objectification did not increase victim blame. The implications of these findings for future research on sexual objectification, gender differences in rape perception, and sexual assault are discussed.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Shades of Sexualization: When Sexualization Becomes Sexual Objectification

Sexualization in mass media is a widespread phenomenon. Although sexualization and sexual objectification are often used as synonymous, they are two different concepts. Across two studies, we investigated how sexualization affects perceptions of women (Study 1) and men (Study 2) as sexual objects. Participants were asked to judge sexual objectification, competence, and sexiness of female and male models portrayed with different degrees of sexualization, namely, as Non-Revealing (dressed), merely Revealing (undressed), and Sexualized Revealing (undressed and provocative). The results of both studies showed that as the level of sexualization increased so did participants’ perceptions of the targets as sexual objects. However, the level of sexualization affected perceived competence and sexiness differently depending on the target’s gender. Male models’ competence decreased as the level of sexualization increased, whereas female models portrayed as merely Revealing and as Sexualized Revealing were judged as equally incompetent. Male targets’ sexiness was not affected by the level of portrayals’ sexualization, whereas Sexualized Revealing portrayals enhanced the perceived sexiness of female targets. Finally, in Study 2, the results showed that male targets in Sexualized Revealing portrayals were judged as less masculine. Our findings suggest that sexualization contributes similarly to the perception of both women and men as sexual objects but affects other variables depending on the target’s gender. Our work extends previous literature and informs us about the consequences that sexualization of men and women have on others’ judgments

When sex doesn't sell: using sexualized images of women reduces support for ethical campaigns

Images of scantily clad women are used by advertisers to make products more attractive to men. This "sex sells" approach is increasingly employed to promote ethical causes, most prominently by the animal-rights organization PETA. Yet sexualized images can dehumanize women, leaving an unresolved paradox - is it effective to advertise an ethical cause using unethical means? In Study 1, a sample of Australian male undergraduates (N = 82) viewed PETA advertisements containing either sexualized or non-sexualized images of women. Intentions to support the ethical organization were reduced for those exposed to the sexualized advertising, and this was explained by their dehumanization of the sexualized women, and not by increased arousal. Study 2 used a mixed-gender community sample from the United States (N = 280), replicating this finding and extending it by showing that behaviors helpful to the ethical cause diminished after viewing the sexualized advertisements, which was again mediated by the dehumanization of the women depicted. Alternative explanations relating to the reduced credibility of the sexualized women and their objectification were not supported. When promoting ethical causes, organizations may benefit from using advertising strategies that do not dehumanize women
