Intravenous drug abuse and Type 1 diabetes: financial and healthcare implications.

AIMS: To determine the morbidity, mortality and healthcare costs of intravenous drug-abusing patients with Type 1 diabetes (IVDA-DM), who are admitted to hospital. METHODS: Retrospective case note analysis of admissions, complications and cost estimation over a 6-year period. Each drug-abusing patient (IVDA-DM) (n = 9) was compared with two controls (n = 18) with Type 1 diabetes but without a history of intravenous drug abuse (DM-controls). Admissions were also analysed for patients with intravenous drug abuse, but without Type 1 diabetes (IVDA-controls) (n = 198). Admissions were at a University teaching hospital in Liverpool, UK. DM-controls were drawn from a population attending diabetes outpatient clinics between 1997 and 2002 at the same hospital. The main outcome measures were: the duration and healthcare costs of hospital admissions per year, outpatient attendances per year, glycated haemoglobin (HbA(1c)), weight, micro- and macrovascular complications and mortality. RESULTS: Multiple admissions, mainly related to ketoacidosis, led to marked differences in mean (95% CI) inpatient days per year per patient [IVDA-DM 28.1 (13.6-42.7) vs. DM-control 1.1 (0.2-1.9); P < 0.0001], mean inpatient days per year per patient in critical care bed (IVDA-DM 1.7 (-0.7-4.2) vs. DM-control 0; P < 0.02) and mean costs of admission, per patient per year (pound sterling 7320 vs. pound sterling 230). The IVDA-DM group frequently omitted insulin, were underweight, failed to attend as outpatients and five had died by the end of 2002. The IVDA-controls spent considerably less time in hospital [3.4 (2.8-3.9) days per patient per year]. CONCLUSION: IVDA-DM patients have higher rates of diabetes complications, are admitted more frequently and have a high mortality compared with DM and IVDA-controls. The cost of inpatient care of this small group of patients was considerable.     

听觉诱发电位指数指导全凭静脉麻醉期间病人输注异丙酚的效果

目的探讨听觉诱发电位指数(AAI)指导全凭静脉麻醉期间病人输注异丙酚的效果。方法择期全麻下行腹腔镜胆囊切除术病人60例,ASAⅠ或Ⅱ级,随机分为2组(n=30):试验组(Ⅰ组)和对照组(Ⅱ组)。静脉诱导气管插管后,持续输注0．2μg·kg-1·min-1瑞芬太尼以维持合适的麻醉深度。Ⅰ组通过监测AAI调节异丙酚输注速率,使AAI维持在30以下,Ⅱ组根据病人血压及心率调节异丙酚输注速率,每5分钟增减0．01 mg·kg-1·min-1异丙酚。记录气腹前(T1)、气腹后(T2)、分离胆囊(T3)、腹腔冲洗(T4)、手术结束(T5)时2组的血压、心率、AAI和输注异丙酚的速率,同时记录2组异丙酚、维库溴铵、瑞芬太尼用量、术毕睁眼时间、应答时间和拔管时间。结果2组各时间点AAI差异有统计学意义(P<0．05),与Ⅱ组相比,Ⅰ组输注异丙酚速率以及总用量减少(P<0．05)。术后24 h随访病人均无术中知晓。结论AAI指导全凭静脉麻醉输注异丙酚用于腹腔镜胆囊切除术病人,可较好的控制麻醉深度,指导合理用药,避免病人术中知晓。     

前列腺癌细胞株Du145裸鼠胫骨部骨肿瘤转移模型的建立

目的:建立一种裸鼠前列腺癌骨转移模型,观察肿瘤局部生长和远处转移情况,并进一步探讨其应用价值。方法:9只6周龄雄性BALB/C裸鼠麻醉后,将前肢及左后肢固定,以1 m l TB针筒-29G针头从胫骨头关节窝,刺入骨髓腔缓缓注入人前列腺癌Du145细胞悬液30μl(约5×106个细胞)至骨髓腔,以建立前列腺癌骨转移模型。观察裸鼠生命体征变化。于濒死状态下处死,取右后肢及其附近淋巴结、肺脏和肝脏等标本,用40 m l/L甲醛固定、石蜡包埋、苏木精-伊红染色后显微镜下观察。结果:9只裸鼠中有6只模型建立成功。接种后平均48 d裸鼠出现跛行现象,右后肢胫骨部可触及米粒大小的包块,质硬,进一步发展至小鼠行走障碍。55 d后出现恶病质,解剖后发现右后肢胫骨部骨质疏松,局部有“腐肉”样组织突出髓腔,填塞肌肉间隙,病理证实为肿瘤组织。肝脏泛黄、被膜皱缩,镜下呈急性重型肝炎的病理改变。结论:胫骨内注射细胞悬液制作裸鼠前列腺癌骨转移模型较好地模拟了人前列腺癌在骨骼微环境中的生长及转归情况,是研究前列腺肿瘤骨转移的适宜模型。

Epidural block for obstetrics: Comparison of bolus injection of local anesthetic with gravity flow technique

Study Objective: To test the hypothesis that slow administration of local anesthetic into the epidural space by gravity flow reduces the incidence of signs and symptoms of unintended injection.

Design: Prospective, randomized study.

Setting: Teaching hospital.

Patients: 600 ASA physical status I and II parturients scheduled for labor and delivery or elective cesarean section.

Interventions: After identification of the epidural space with pulsations of an air-fluid column, parturients for vaginal delivery (n = 380) were randomized to receive a test dose of 3 ml 3% 2-chloroprocaine with epinephrine 20 μg, two doses of 7 ml bupivacaine 0.03 % with sufentanil 1 μg/ml and epinephrine 2 μg/ml by either gravity flow (Group 1) given over 30 seconds or by bolus injection (Group 2) given over 5 seconds through the epidural needle; parturients for Cesarean delivery (n = 220) were randomized to receive a test dose and two doses of 6 ml lidocaine 2 % with sufentanil 1 μg/ml and epinephrine 2 μg/ml by either gravity flow or by bolus injection through the epidural needle. Changes in maternal heart rate (HR) and blood pressure, signs of intravascular injection, and adverse effects of epidural bupivacaine-sufentanil were recorded after each dose.

Measurements and Main Results: Gravity flow administration (Group 1) was associated with a smaller increase in mean maternal HR (p < 0.001), less hypotension (p < 0.01), sedation (p < 0.01), nausea (p = 0.01), and segmental spread (p < 0.0001) than were corresponding doses given by traditional bolus injection (Group 1) for vaginal or Cesarean deliveries. The incidence of systemic toxicity was zero of 300 (0%) with gravity flow and 4 of 300 (1.3%) by bolus injection, p = 0.12, Fisher's exact test. No patient in either group had an accidental intrathecal injection.

Conclusion: Gravity flow administration of local anesthetic-opioid solution during epidural block for obstetrics was associated with fewer signs of systemic drug absorption and cardiovascular perturbations than was the traditional bolus injection. This study supports the current opinion that slow administration of local anesthetic during epidural black contributes to fewer adverse events.
