Time-dependent changes in sensitivity to apomorphine and monoamine receptors following withdrawal from continuous cocaine administration in rats

The effects of withdrawal from continuous administration of cocaine on behavioral sensitivity to apomorphine and monoamine receptor density were examined in rats. Subdermal minipumps that delivered either saline or 20 mg/kg/day cocaine hydrochloride were implanted for 2 weeks. Apomorphine-induced stereotypy (0.5 mg/kg, SC) was examined in separate groups of rats either 4 hr or 7, 28, or 60 days after removal of the minipumps. Transient enhanced sensitivity to apomorphine-induced stereotypy occurred during the course of withdrawal. Animals withdrawn from cocaine for 4 hours did not differ from controls in their sensitivity to apomorphine, whereas animals withdrawn from cocaine for 7 days exhibited an increase in apomorphine-induced oral stereotypy relative to controls. However, the enhanced stereotypy response was no longer evident in animals withdrawn for 28–60 days. The animals were sacrificed after behavioral testing, and their brains were assayed for changes in monoamine receptor density in the frontal cortex, caudate-putamen, and nucleus accumbens. The density of ³H-SCH-23390-labeled D1 receptors was altered in all three regions examined in a time-dependent manner that paralleled the changes in behavioral sensitivity to apomorphine. There was a transient decrease in D1 receptor density that was evident by 7 days following withdrawal from continuous cocaine administration and was no longer evident 28 or 60 days posttreatment. There were no changes in ³H-spiroperidol-labeled D2 receptors, ¹²⁵-pindolol-labeled β-adrenergic receptors, or ³H-ketanserin-labeled 5-HT₂ receptors in any of the regions examined at both 4 hr and 7 days after termination of the cocaine infusion. These findings are discussed in terms of their relevance to developing pharmacologic treatments for withdrawal from cocaine. © 1994 Wiley-Liss, Inc.

The use of oral sedatives in dental care

Oral administration of tranquillizing and anxiety-suppressing drugs has long been the commonest method of achieving light sedation. The benzodiazepines are the drugs of first choice. Benzodiazepines given orally may be indicated to avoid 'treatment stress', alleviate mild anxiety before dental treatment, and facilitate sleep on the night before the treatment. Furthermore, they could be used for the dental treatment of medically poor risk patients, particularly those with cardiovascular disease. The drug can be given either in a fractionated dose or a single dose. The recommended doses for diazepam vary from 0.1–0.8 mg/kg body weight, depending on age, with higher doses in children and lower doses in elderly patients. Few side effects are reported.

以渗透压微泵植入小鼠皮下恒速给予丙戊酸钠，在达到理论稳态浓度时间后，血浆药浓呈昼夜变化，白昼高于夜间，峰值位于明期末。药动学研究揭示丙戊酸血药浓度的昼夜差异可能与其清除率及分布容积的昼夜变化有关。     

Using Queueing Theory to Increase the Effectiveness of Emergency Department Provider Staffing

Objectives: Significant variation in emergency department (ED) patient arrival rates necessitates the adjustment of staffing patterns to optimize the timely care of patients. This study evaluated the effectiveness of a queueing model in identifying provider staffing patterns to reduce the fraction of patients who leave without being seen. Methods: The authors collected detailed ED arrival data from an urban hospital and used a Lag SIPP queueing analysis to gain insights on how to change provider staffing to decrease the proportion of patients who leave without being seen. The authors then compared this proportion for the same 39‐week period before and after the resulting changes. Results: Despite an increase in arrival volume of 1,078 patients (6.3%), an average increase in provider hours of 12 hours per week (3.1%) resulted in 258 fewer patients who left without being seen. This represents a decrease in the proportion of patients who left without being seen by 22.9%. Restricting attention to a four‐day subset of the week during which there was no increase in total provider hours, a reallocation of providers based on the queueing model resulted in 161 fewer patients who left without being seen (21.7%), despite an additional 548 patients (5.5%) arriving in the second half of the study. Conclusions: Timely access to a provider is a critical dimension of ED quality performance. In an environment in which EDs are often understaffed, analyses of arrival patterns and the use of queueing models can be extremely useful in identifying the most effective allocation of staff.     

“分步给药”在低氧易感患者无痛苦胃镜检查中安全性的探讨

目的 探讨在低氧易感患者无痛苦胃镜检查中采用分步给药的安全性和镇静/镇痛效果.方法 接受胃镜检查的180例患者,其中有鼾症、或咳嗽、咳痰症状的患者120例单双号随机入选Ⅰ组(分步给药组)和Ⅱ组(普通组),60例无鼾症、咳嗽、咳痰症状的患者为Ⅲ组(常规给药组),Ⅰ组采用分步给药法,Ⅲ组采用常规给药法对患者实施胃镜检查前的镇静/镇痛术,Ⅱ组则进行普通胃镜检查,分析2种镇静法对SBP、DBP、SpO2、HR、清醒时间、患者反应、患者对检查过程的感受以及是否愿意再次接受检查的影响,评价分步给药法在低氧易感患者无痛苦胃镜检查中的安全性和镇静/镇痛效果.结果 Ⅰ组、Ⅲ组检查中SBP、DBP变化无明显差异(均P＞0.05),Ⅰ组检查前、中SpO2的变化小于Ⅲ组(均P＜0.01);Ⅰ组进镜时咽部受刺激产生的恶心咽吐、流涎、咳嗽、躁动反应多于Ⅲ组(均P＜0.01),但较Ⅱ组少(均P＜0.01);Ⅰ组对胃镜检查的评价与Ⅲ组无明显差异(P＞0.05),与Ⅱ组相比有明显差异(P＜0.01).结论 分步给药法是一种适用于低氧易感患者无痛胃镜检查的安全、有效的镇静/镇痛方法.
