Assessing the Need for Anesthesia and Sedation Services in Kuwaiti Dental Practice

The objective of this study was to examine the public health relevance of the prevalence of dental fear in Kuwait and the resultant barrier that it creates regarding access to dental care. The study analysis demonstrated a high prevalence of dental fear and anxiety in the Kuwaiti population and a perceived need for anesthesia services by dental care providers. The telephone survey of the general population showed nearly 35% of respondents reported being somewhat nervous, very nervous, or terrified about going to the dentist. In addition, about 36% of the population postponed their dental treatment because of fear. Respondents showed a preference to receive sedation and anesthesia services as a means of anxiety relief, and they were willing to go to the dentist more often when such services were available. People with high fear and anxiety preferred to receive some type of medication to relieve their anxiety. In conclusion, the significance and importance of the need for anesthesia services to enhance the public health of dental patients in Kuwait has been demonstrated, and improvements are needed in anesthesia and sedation training of Kuwaiti dental care providers.

Multimodality Rodent Imaging Chambers for Use Under Barrier Conditions with Gas Anesthesia

Purpose  The ability to reproducibly and repeatedly image rodents in noninvasive imaging systems, such as small-animal positron emission tomography (PET) and computed tomography (CT), requires a reliable method for anesthetizing, positioning, and heating animals in a simple reproducible manner. In this paper, we demonstrate that mice and rats can be reproducibly and repeatedly imaged using an imaging chamber designed to be rigidly mounted on multiple imaging systems. Procedures  Mouse and rat imaging chambers were made of acrylic plastic and aluminum. MicroCT scans were used to evaluate the positioning reproducibility of the chambers in multimodality and longitudinal imaging studies. The ability of the chambers to maintain mouse and rat body temperatures while anesthetized with gas anesthesia was also evaluated. Results  Both the mouse and rat imaging chambers were able to reproducibly position the animals in the imaging systems with a small degree of error. Placement of the mouse in the mouse imaging chamber resulted in a mean distance of 0.23 mm per reference point in multimodality studies, whereas for longitudinal studies the mean difference was 1.11 mm. The rat chamber resulted in a mean difference of 0.46 mm in multimodality studies and a mean difference of 4.31 mm in longitudinal studies per reference point. The chambers maintained rodent body temperatures at the set point temperature of 38°C. Conclusions  The rodent imaging chambers were able to reproducibly position rodents in tomographs with a small degree of variability and were compatible with routine use. The embedded anesthetic line and heating system was capable of maintaining the rodent’s temperature and anesthetic state, thereby enhancing rodent health and improving data collection reliability.     

重度妊高征持续性硬膜外麻醉剖宫产血压变化的临床分析

目的 :了解重度妊高征持续性硬膜外麻醉下剖宫产时的血压变化规律。方法 :选择重度妊高征孕妇和正常孕妇各 1 0 2例 ,比较持续性硬膜外麻醉下剖宫产术前、术中最低、麻醉后、术后的血压变化及术中输液量。结果 :麻醉后妊高征组与对照组的最低血压及麻醉后血压均较麻醉前血压显著降低 (P<0 .0 1 ) ;血压下降幅度妊高征组显著大于对照组 (P<0 .0 1 ) ;术中输液量妊高征组显著高于对照组 (P<0 .0 5) ;两组最低血压中舒张压相近 (P>0 .0 5) ;术后血压回升稍高于麻醉前血压。结论 :持续性硬膜外麻醉能够暂时解除血管痉挛及降低血管的紧张度 ,使血压下降 ;术后血管紧张度恢复及术中输液 ,造成术后有效循环血容量相对增加 ,致使血压回升 ,诱发子痫。     

腰麻和硬膜外麻醉对手术患者血液流变学的影响比较

目的比较腹部以下手术腰麻和硬膜外麻醉在术中对患者血液流变学的影响。方法选取美国麻醉协会标准（ASA）Ⅰ-Ⅱ级择期手术的患者78例，随机分为两组：A纽为腰麻组，经常规的消毒铺巾穿刺置管后给予0．75％布比卡因1．8ml；B组为硬膜外麻醉组，经常规的消毒铺巾穿刺置管后，硬膜外给罗哌卡因15～20d，术中每隔50min硬膜外给罗哌卡因5～7ml；A组术后肌注哌替啶镇痛，B组术后24h内用0．5％的罗哌卡因镇痛。分别于麻醉前、麻醉后30min、60min、90min各取桡动脉血5～10ml，测血液流变学指标。结果两组麻醉后30min全血高切及低切黏度、血细胞比容及红细胞聚集指数下降（P〈0．05），但B组这几项指标下降明显且持续时间长，且有血浆黏度及纤维蛋白原浓度的下降（P〈0．05）。结论腰麻有利于保持在术中对患者血液流变学的平稳，而硬膜外阻滞对血液流变学的影响更有利于预防术后患者下肢静脉血栓形成。
