Epidural Administration of Morphine Postoperatively for Morbidly Obese Patients

Two groups of morbidly obese patients undergoing a gastric stapling procedure were compared. Patients in group I received 5 mg of morphine through a lumbar epidural catheter immediately after the surgical procedure while group II patients were treated conventionally with parenterally administered morphine. In group I less narcotics were needed and patients were able to walk earlier than in group II. Length of hospital stay, time to removal of the nasogastric tube and postoperative pulmonary function were not significantly different between groups. Two patients in group I and one patient in group II had generalized pruritus, and in one study patient bradypnea developed in association with the epidural administration of morphine. It is concluded that morbidly obese patients can benefit from epidurally administered morphine and that this form of therapy has a role in the management of these patients.     

Epidural Co-Administration of Dexmedetomidine and Levobupivacaine Improves the Gastrointestinal Motility Function after Colonic Resection in Comparison to Co-Administration of Morphine and Levobupivacaine

Gastrointestinal motility may be impaired after intestinal surgery. Epidural morphine is effective in controlling postoperative pain, but can further reduce gastrointestinal motility. Here, we aimed to investigate the effects of epidural dexmedetomidine on gastrointestinal motility in patients undergoing colonic resection. Seventy-four patients undergoing colonic resection were enrolled in this clinical trial and allocated randomly to treatment with dexmedetomidine (D group) or morphine (M group). The D group received a loading dose epidural administration of 3 ml dexmedetomidine (0.5 μg kg^-1) and then a continuous epidural administration of 80 μg dexmedetomidine in 150 ml levobupivacaine (0.125%) at 3 ml h^-1 for two days. The M group received a loading dose epidural administration of 3 ml morphine (0.03 mg kg^-1) and then a continuous epidural administration of 4.5 mg morphine in 150 ml levobupivacaine at 3 ml h^-1 for two days. Verbal rating score (VRS), postoperative analgesic requirements, side effects related to analgesia, the time to postoperative first flatus (FFL) and first feces (FFE) were recorded. VRS and postoperative analgesic requirements were not significantly different between treatment groups. In contrast, the time to FFL and time to FFE were significant longer in M group in comparison to D group (P < 0.05). Moreover, patients in M group had a significantly higher incidence of nausea, vomiting, and pruritus (P < 0.05). No patients showed neurologic deficits in either group. In comparison to morphine, epidural dexmedetomidine is safe and beneficial for the recovery of gastrointestinal motility after colonic resection when used as an adjunct with levobupivacaine for postoperative pain control.

血肌酐与非ST段抬高急性冠脉综合征冠脉病变程度及其预后

目的:研究血清肌酐(serum creatinine,SCr)与非ST段抬高急性冠脉综合征(non-ST-elevation acute coronary syndrome,NSTE-ACS)患者冠脉病变程度及其预后的关系。方法:对293例患者进行回顾性分析,依据冠脉造影结果分为NSTE-ACS组和非冠心病组。根据Gensini积分系统,评价NSTE-ACS患者冠脉病变程度,并将患者分为轻度病变组、中度病变组和重度病变组。检测患者SCr水平,应用SPSS16.0分析SCr与NSTE-ACS患者冠脉病变程度及其预后关系。结果:(1)与非冠心病组相比,NSTE-ACS患者SCr较高(P0.05);其中,重度冠脉病变NSTE-ACS患者SCr水平尤高(P0.001)。(2)SCr是NSTE-ACS冠脉病变的危险因子;SCr与NSTE-ACS冠脉病变程度呈正相关(r=0.263,P0.000);SCr与NSTE-ACS主要心血管不良事件(Major Adverse Cardiovascular Events,MACE)呈正相关(r=0.183,P0.01)。结论:SCr是NSTE-ACS患者冠脉病变的独立危险因子,且与NSTE-ACS患者预后相关。SCr对于NSTE-ACS的诊疗有潜在临床价值。     

Duke Treadmill Score in prioritizing patients for coronary angiography: retrospective study of a Croatian regional hospital

Aim of the study was to determine the potential of Duke Treadmill Score (DTS) in prioritizing patients for coronary angiography in a transitional country clinical setting. We analyzed 114patients with suspected stable coronary artery disease who underwent exercise treadmill testing, and coronary angiography in Slavonski Brod General Hospital. DTS was calculated from treadmill test as: exercise time--(5 x ST deviation in mm)--(4 x exercise angina). Regarding the score, patients were grouped into three groups of risk for coronary artery disease: low risk, medium risk, and high risk patients. All patients underwent coronary angiography, and were grouped in accordance to the severity of the coronary artery disease into three groups: insignificant, significant, or severe coronary artery disease. All patients scored as high risk DTS had significant or severe coronary artery disease. Medium and low risk DTS patients had insignificant coronary artery disease in 50%, and 90% of cases, respectively. Medium risk patients with significant or severe coronary artery disease were significantly older, and had more frequent history of typical chest pain with higher number of episodes per week (P<0.05), whereas there were no differences regarding gender or presence of risk factors. There were no significant differences among medium risk patients regarding the severity of coronary artery disease in exercise time or ST deviation. However, the presence of limiting exercise angina in medium risk patients was significantly more related with significant and severe coronary artery disease (P<0.05). High risk DTS result showed great potential in stratifying patients for immediate coronary angiography. This scoring system may be used in prioritizing patients for coronary angiography in a transitional clinical setting.     

帕瑞昔布在肺癌手术多模式镇痛效果及其对凝血功能的影响

目的:研究帕瑞昔布在胸部肺癌手术后多模式镇痛效果及其对凝血功能的影响。方法:自2012年1月到2013年12月期间,全麻复合硬膜外麻醉下实施肺癌手术病人120例,分为3组,对照组(C组)和不同帕瑞昔布钠处理组(P1组和P2组)。对照组采用硬膜外镇痛,P1此基础上术前静脉用帕瑞昔布,P2组在P1基础上术后加用帕瑞昔布。观察三组手术时间、术中出血量、术中瑞芬太尼及术后吗啡用量、不同时间段VAS和术前术后凝血功能。结果:C组、P1和P2组术中出血量三组间的差异有统计学意义,P2组出血量最少(p0.05)。C组、P1和P2组术中瑞芬太尼和术后吗啡使用剂量差异有统计学意义(P均0.05)。C组、P1组和P2组术后6个月时间内疼痛发生率和6个月时间内疼痛发生天数差异有统计学意义(P均0.05)。术中PT、APTT在三组间的差异有统计学意义(P0.05)。结论:帕瑞昔布可降低病人开胸术后慢性疼痛综合征的发生,增加凝血功能,减少吗啡用量,且不增加不良反应发生几率,临床应用安全性可靠。     

Efficiency of medical versus endovascular treatment using drug-eluting stents in coronary heart disease patients with extensive lesion of the coronary bed

The goal of the study was to assess the long-term results of endovascular treatment using drug-eluting stents in coronary heart disease patients with extensive coronary artery lesion. The study covered 478 patients with diffuse coronary artery lesion, including 220 patients receiving endovascular treatment and 258 having medical treatment (a comparison group). The immediate angiographic results and long-term clinical efficiency of endovascular treatment using rapamycin-eluting stents were studied. The follow-up was 2 years. Repeat follow-ups were undertaken1and 2 years later. The immediate angiographic success rate of endovascular treatment for diffuse coronary artery lesions was 89.5%. The two-year follow-up showed the efficiency and expediency of endovascular treatment for extensive coronary artery lesions: the symptoms of angina pectoris occurred significantly less frequently symptoms, the exercise endurance was higher, and the need for antianginal medications was less in the invasively treated patients.     

Permeability of epidural somatostatin and morphine into the intrathecal space of dogs

In an in vivo saline perfusate of the intrathecal space of 6 dogs, the concentration of somatostatin was determined by radioimmunoassay before and over 2 h after epidural administration of 3 mg somatostatin. The total recovered amount of somatostatin was negligible, about 0.02%. However, within 50 min after the bolus epidural injection of somatostatin, the concentration per ml perfusate increased from 0.1 +/- 0.02 ng/ml to 138 +/- 102 ng/ml (P less than 0.001) and declined to 4 +/- 1.7 ng/ml after 120 min. This increase of the somatostatin concentration by 3 orders of magnitude might explain why epidurally administered somatostatin is effective in treatment of acute and chronic pain. In a control investigation with epidural morphine in another 6 dogs to prove the feasibility of the method, the total recovered amount of morphine in the intrathecal perfusate over 2 h was about 12%.     

MYOCARDIAL INFARCTION FOLLOWING CAROTID ENDARTERECTOMY

Myocardial infarction has been the major cause of mortality following operation for cerebrovascular insufficiency. In our institution, a clinical diagnosis of coronary artery disease was made in 37 of 125 (29.6%) consecutive male patients having carotid endarterectomy. Six of these 37 patients developed postoperative myocardial infarction. In contrast, none of the 88 patients without coronary artery disease developed myocardial infarction. A more recently treated group of 20 patients who had undergone carotid artery surgery and had previously undergone coronary artery bypass for angina did not develop postoperative myocardial infarction. These data suggest that in patients with both coronary artery and carotid artery disease, prior or concomitant coronary artery bypass should be considered. Myocardial infarction has been the leading cause of early and late death following operation for cerebrovascular insufficiency.(1) DeBakey(2) found operative mortality in patients having surgery for cerebrovascular insufficiency directly related to the incidence of coronary artery disease. An increased operative mortality due to reinfarction has been found in patients recovering from recent myocardial infarction.(3) Cooley(4) found that in patients having aortocoronary bypass there was no increased operative mortality 30 days after myocardial infarction and this may apply to patients having carotid endarterectomy. Subendocardial postoperative infarction associated with minor T wave changes and slight enzyme elevation had a better prognosis than did transmural infarction causing significant Q waves, sequential ST and T wave changes and marked enzyme elevations.(5) The purpose of this study was to document our experience with myocardial infarction in patients undergoing carotid artery operation for clinical coronary artery disease. Consideration of the role of saphenous vein bypass in those patients with coronary artery disease was the background for this review even though the evidence that myocardial infarction can be prevented with saphenous vein bypass operation is only preliminary at the present time.(6)

Incidence of anomalous origin of coronary artery in 1879 Chinese adults on dual-source CT angiography

Background and Objective. Dual-source CT (DSCT) has been used to detect coronary artery anomalies. The purpose of this study was to assess the incidence of anomalous origin of the coronary artery in Chinese adults. Methods. We summarised all patients who underwent DSCT coronary angiography (CTCA) from December 2006 to February 2008, and data of anomalous origin of the coronary artery in Chinese adults were recorded. Results. 1879 patients underwent CTCA during that period; 24 patients with an anomalous origin of the coronary artery were detected, giving an incidence of 1.3%. Fifteen patients had an anomalous origin of the right coronary artery (12 from left coronary sinus, 3 high takeoff), eight patients had an anomalous origin of the left coronary artery (LCA from posterior sinus of Valsalva in three cases, LCX from the right coronary sinus, LCX from RCA, high takeoff, LCA from right coronary sinus, and single coronary artery in one case, respectively), and one patient had an anomalous origin of both coronary arteries (high takeoff). Conclusion. The incidence of anomalous origin of the coronary artery in Chinese adults in this study is 1.3%. DSCT can clearly visualise the anomalous origin and course of the coronary artery and is a useful screening modality. (Neth Heart J 2010;18:466-70.)     

Natural history of coronary artery disease in relation to angiographic, hemodynamic and clinical factors

Studying the natural history of coronary artery disease could provide a frame of reference for prognosis and appraisal of treatment for patients having this disease. We studied a total of 465 consecutive patients with angiographically significant coronary artery disease, defined as greater than 50% stenosis in at least one principal artery, who were followed with medical treatment only from 1 to 7 years. Excluding patients with left main coronary disease, there were 73 deaths, of whom 63 were cardiac. The 5-year cumulative survival rates were 72% for the entire group, 87% for single vessel disease, 73% for double vessel disease and 51% for triple vessel disease. In single vessel disease, patients with left anterior descending artery involvement tended to have higher mortality. In double vessel disease, survival was worse with the combination of left anterior descending and right coronary artery involvements than the other 2 combinations. A history of myocardial infarction was not significantly different from angina in 5-year survival rate. Nevertheless, an abnormal Q-wave in ECG was associated with lower survival. History of hypertension and electrocardiographic left ventricular hypertrophy did not affect survival. While congestive heart failure, abnormal resting LVEDP and left ventricular asynergy were all associated with reduced survival. The left ventricular ejection fraction had highly prognostic value, only 42% of patients survived with ejection fraction less than 0.3 at the end of 5 years after angiography.     

Predictive value of the ear-crease sign in coronary artery disease.

The value of the ear-crease sign in predicting the presence of coronary artery disease was studied in 340 consecutive patients who underwent coronary arteriography. In this selected population, 75.6% of whom had coronary artery disease, the sensitivity of the sign was 59.5%, the specificity 81.9% and the positive predictive value 91.1%. The sign was associated with increasing age but was also independently associated with obstructive coronary artery disease. No significant correlation was found between the sign and the presence of risk factors or other signs of such disease, except for corneal arcus. In symptomatic patients the sign suggested the presence of more extensive coronary artery disease. In an asymptomatic population with a low prevalence of coronary artery disease it appears to be of limited value in predicting obstructive coronary artery disease. However, it may identify a subset of patients prone to early ageing and to the early development of coronary artery disease, whose prognosis might be improved by early preventive measures.     

Chronic Total Occlusions in Sweden – A Report from the Swedish Coronary Angiography and Angioplasty Registry (SCAAR)

Introduction

Evidence for the current guidelines for the treatment of patients with chronic total occlusions (CTO) in coronary arteries is limited. In this study we identified all CTO patients registered in the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) and studied the prevalence, patient characteristics and treatment decisions for CTO in Sweden.

Methods and Results

Between January 2005 and January 2012, 276,931 procedures (coronary angiography or percutaneous coronary intervention) were performed in 215,836 patients registered in SCAAR. We identified all patients who had 100% luminal diameter stenosis known or assumed to be ≥3 months old. After exclusion of patients with previous coronary artery bypass graft (CABG) surgery or coronary occlusions due to acute coronary syndrome, we identified 16,818 CTO patients. A CTO was present in 10.9% of all coronary angiographies and in 16.0% of patients with coronary artery disease. The majority of CTO patients were treated conservatively and PCI of CTO accounted for only 5.8% of all PCI procedures. CTO patients with diabetes and multivessel disease were more likely to be referred to CABG.

Conclusion

CTO is a common finding in Swedish patients undergoing coronary angiography but the number of CTO procedures in Sweden is low. Patients with CTO are a high-risk subgroup of patients with coronary artery disease. SCAAR has the largest register of CTO patients and therefore may be valuable for studies of clinical importance of CTO and optimal treatment for CTO patients.     

冠状动脉弥漫性长病变治疗的研究进展

冠心病目前已经成为全球性关注的健康问题,为当今人类一大灾难性疾病。既往研究表明,冠状动脉弥漫性长病变占冠心病总患者约20%,冠状动脉弥漫性长病变患者其动脉粥样硬化的病变范围更加广泛,病变呈弥漫性,而且更多累及左主干,常常伴有血管直径小,血管成角、钙化、扭曲等特点,而且多发生于高龄、糖尿病患者中,以上特点又决定了冠状动脉弥漫性长病变成为冠心病治疗的又一难题。因此,有效的预防与治疗冠状动脉弥漫性长病变,已成为目前的关注重点与热点,本文概述了冠状动脉弥漫性长病变临床治疗中的常用方法以及各方法的疗效与优劣之势,多年临床实践经验表明PCI治疗仍占有主导位置,虽然目前冠状动脉弥漫性长病变的介入治疗应用药物洗脱支架的已经取得良好的临床效果,在很大程度降低了心血管事件发生率和再次血管重建率,但药物洗脱支架支架治疗冠状动脉弥漫性长病变的远期疗效仍在评估中。     

Analysis of preincisional and postincisional treatment with alpha2-adrenoreceptor agonist clonidine regarding analgesic consumption and hemodynamic stability in surgical patients

Preemptive analgesia aims to prevent the sensitization of central nervous system, hence the development of pathologic pain after tissular injury. The aim of the study was to assess the effect of preincisional clonidine treatment on analgesic consumption and hemodynamic stability compared to clonidine administered at the end of the operation and control group. Ninety-one patients undergoing elective colorectal surgery were randomly assigned to four groups: peroral clonidine before operation, epidural clonidine before operation, epidural clonidine at the end of operation, and epidural saline before operation as a control group. After the operation, patient-controlled analgesia with epidural morphine was instituted. Analgesic consumption, blood pressure and heart rate were obtained at 1, 2, 6 and 24 h postoperatively, and the cumulative consumption of analgesics was assessed at the end of the study period. Significant differences (p < 0.05) in postoperative systolic blood pressure, with highest hemodynamic stability was observed at 1 h and 6 h in the group of patients administered epidural clonidine before operation. In this group of patients we found significant reduction in analgesic consumption during the study period (p < 0.05), compared to other groups. The cumulative consumption of analgesics assessed at the end of the study period was significantly reduced (p < 0.05) in the group of patients administered epidural clonidine before operation (8.40 +/- 3.74, respectively) as compared with the peroral clonidine before operation (16.79 +/- 5.75, respectively), epidural clonidine at the end of the operation (11.11 +/- 4.24, respectively) and control group of patients (18.00 +/- 6.45, respectively). Preincisional administration of epidural clonidine was associated with a significantly lower analgesic use, lower cumulative analgesic consumption and greater hemodynamic stability, in comparison with other groups.     

高血压患者血压控制水平、血脂水平及颈动脉斑块与冠脉病变的关系

目的:探讨血压控制水平、血脂水平和颈动脉斑块与高血压患者冠脉病变程度和病变支数的关系。方法:回顾性分析2014年01月至2016年05月收住于南京中医药大学附属江苏省中西医结合医院心血管科的原发性高血压患者273例,按血压控制水平分为达标组和未达标组。按颈动脉超声结果判断有无斑块,冠状动脉造影结果使用Gensini评分和病变支数表示,并检测血脂指标。结果:血压控制达标者130人(47.61%),颈动脉有斑块者193例(70.70%)。与血压控制达标患者相比,血压控制不达标者冠脉病变支数及冠脉狭窄程度得分均明显增加(P0.05)。血压不达标合并斑块患者冠脉病变支数和狭窄程度与血压达标无斑块、血压达标合并斑块及血压不达标无斑块患者相比均明显增加(P0.001)。患者HDL-C水平与冠状动脉狭窄程度呈负相关(r=-0.139,P=0.022),AI与冠状动脉狭窄程度呈正相关(r=0.136,P=0.025),LDL/HDL-C和AI与冠脉病变支数均呈正相关,分别为(r=0.128,P=0.035)和(r=0.137,P=0.023)。结论:血压控制不佳,高血脂和颈动脉斑块形成可增加高血压患者冠脉病变的严重程度。     

Cold pressor test in diagnosis of coronary artery disease: echophonocardiographic method.

The cold pressor test was used to induce myocardial ischaemia in patients with coronary artery disease and the rise in left ventricular filling pressure used as the index of myocardial ischaemia. Left ventricular filling pressure was derived from a non-invasive echophonocardiographic method. A study group of 19 consecutive patients with chest pain underwent the cold pressor test before coronary angiography. Eighteen responded with a rise in filling pressure exceeding 30% and, of these, 17 had serious coronary artery disease (three single vessel, one two vessel, and 13 triple vessel disease; one had coronary artery spasm only). The remaining patient, who showed no rise in filling pressure, did not have coronary artery disease. None of 15 normal controls showed a rise greater than 5% (patients with coronary artery disease versus normal controls p less than 0.001). The cold pressor test would be suitable for patients who cannot or should not exercise and may be combined with exercise electrocardiograms to improve the information content, as it uses a different marker of myocardial ischaemia.     

Coronary Artery Disease with Single Coronary Artery

The authors have reviewed the literature in search of the coexistence of single coronary artery with significant coronary artery disease. Two cases of single right coronary artery are described. In both, the anomalies were unsuspected and diagnosed roentgenographically in life. Both patients had angina pectoris, positive graded-exercise stress tests, and hemodynamically significant obstruction or occlusion to the coronary arteries. In neither case was the stenosis proximal or amenable to bypass surgery.     

Contrasting patterns of coronary atherosclerosis in normocholesterolaemic smokers and patients with familial hypercholesterolaemia.

An angiographic comparison was made of the extent and severity of coronary artery disease in 25 patients with heterozygous familial hypercholesterolaemia and 25 normocholesterolaemic patients with coronary artery disease in whom heavy cigarette consumption was the chief risk factor. The patients with familial hypercholesterolaemia were younger and included a much higher proportion of women than the smokers. Significantly more patients with familial hypercholesterolaemia had disease of the main stem of the left coronary artery (eight v none, p less than 0.05) and triple-vessel disease (18 v four, p less than 0.05). Disease affecting only distal vessels occurred in five smokers, whereas all the patients with familial hypercholesterolaemia showed a combination of proximal and distal lesions. These findings suggest that cigarette smoking and familial hypercholesterolaemia predispose to different patterns of coronary atheroma. Early coronary angiography with a view to coronary artery bypass surgery seems desirable in symptomatic patients with familial hypercholesterolaemia because of the common association of this disorder with life-threatening left main-stem disease.
