Abstract
Abstract
Background
Patients with mental disorders are at increased risk of cardiovascular mortality. While the overall cardiovascular mortality rate in the western world is in decline, there is no up-to-date data on the cardiovascular mortality rates among patients with mental disorders. We aimed to assess the cardiovascular mortality trends over the last two decades among patients with mental co-morbidities in the US.
Methods
Using Centers for Disease Control and Prevention Wide-Ranging, Online Data for Epidemiologic Research (CDC WONDER) Multiple Cause of Death data set, we determined national trends in age-standardized mortality rates attributed to cardiovascular diseases in patients with and without mental disorders, from 1999 to 2020, stratified by mental disorders subtype, age, gender, race, and place of residence.
Results
Among more than 18.7 million cardiovascular deaths in the United States, 13.5% were patients with a concomitant mental disorder. During the study period, among patients with mental disorders, the age-adjusted mortality rate increased by 113.9% (vs 44.8% decline in patients with no mental disorder). In patients with mental disorders, the age-adjusted mortality rate increased more significantly among patients whose mental disorder in secondary to substance abuse (+532.6%) than among with organic mental disorders, such as dementia or delirium (+6.2%), while among patients with mood disorders the age-adjusted CV mortality rate dropped by 23.5%. Men patients, minorities, and residents of more rural areas experienced a more prominent increase in the age-adjusted cardiovascular mortality compared to women, white, and residents of metro areas.
Conclusions
While there was an overall reduction in cardiovascular mortality in the US in the past two decades, we demonstrated an overall increase in cardiovascular mortality among patients with mental disorders. The increase was more significant among patients with substance abuse-related mental disorders, in men, minorities, and residents of rural areas.

Abstract
Abstract. The aim of this comparative research was to determine the chemical composition, antioxidant and antibacterial activities of the methanolic extracts and essential oils (EOs) of Artemisia absinthium aerial parts from five different regions (Bizerte, Zaghouan, Kasserine, Gabes and Tozeur). The polyphenol and flavonoid contents significantly varied (P < 0.05) among the studied regions with maximal contents observed in Zaghouan. Based on the High Performance Liquid Chromatography results, quercetin and isorhamnetin were the main compounds and their percentages were region dependent. The methanolic extract of Zaghouan showed the highest scavenging ability of DPPH (IC50 = 31.46 ± 1.42 µg/mL). A. absinthium EOs from of the different regions were found to interestingly inhibit the growth of both Gram-negative and Gram-positive bacteria strains. The antibacterial effect was strongly related to the organoleptic EO quality. The EO of Zaghouan exhibited an important inhibitory effect with an inhibition zone estimated at 31 mm against Escherichia coli strain. The EO composition was obtained by GC-MS analysis showing the presence of thirty-five compounds. Camphor (49.70 ± 2.34 %) and chamazulene (25.41 ± 0.61 %) were the main constituents. These results suggested that the north regions have a high potential for selecting varieties rich on bioactive volatile and phenolic compounds.
Resumen. El objetivo de esta investigación fue determinar y comparar la composición química, las actividades antioxidantes y antibacterianas de los extractos metanólicos y de los aceites esenciales (AE) de las partes aéreas de Artemisia absinthium de cinco regiones (Bizerta, Zaghouan, Kasserine, Gabes y Tozeur). Los contenidos de polifenoles y flavonoides variaron significativamente (P < 0,05) entre las regiones estudiadas con contenidos máximos observados en Zaghouan. De acuerdo con los resultados de la cromatografía líquida de alta resolución, la quercetina y la isorhamnetina fueron los compuestos principales y sus porcentajes dependieron de la región. El extracto metanólico de Zaghouan mostró la mayor capacidad secuestrante de DPPH (IC50 = 31.46 ± 1.42 µg mL-1). Se descubrió que los aceites esenciales de A. absinthium de las diferentes regiones inhibían de manera interesante el crecimiento de cepas de bacterias Gram-negativas y Gram-positivas. El efecto antibacteriano estuvo fuertemente relacionado con la calidad organoléptica del AE. El AE de Zaghouan exhibió un importante efecto inhibidor con un halo de inhibición estimado en 31 mm frente a una cepa de Escherichia coli. La composición de AE se obtuvo mediante análisis GC-MS y mostró la presencia de treinta y cinco compuestos. El alcanfor (49.70 ± 2.34 %) y el camazuleno (25.41 ± 0.61 %) fueron los principales constituyentes. Estos resultados sugirieron que las regiones del norte tienen un alto potencial para seleccionar variedades ricas en compuestos bioactivos volátiles y fenólicos.

Abstract
Essential oils (EOs) are natural, volatile and aromatic liquids extracted from special plants. EOs are complex mixture of secondary metabolites (terpenes, phenolic compounds, alcohol). EOs possess a wide range of biological activities including antioxidant, antimicrobial and anti-inflammatory ones. Particularly, EOs exhibit pronounced antibacterial and food preservative properties that represent a real potential for the food industry. Numerous EOs have the potential to be used as a food preservative for meat and meat products, vegetables and fruits as well as for dairy products. The main obstacles for using EOs as food preservatives are their safety limits, marked organoleptic effects and possible contamination by chemical products such as pesticides. This review aims to provide an overview of current knowledge about EOs food preservative properties with special emphasis on their antibacterial activities and to support their uses as natural, eco-friendly, safe and easily biodegradable agents for food preservation.

Abstract
This work aims to characterize Thymus capitatus essential oil and to investigate its preservative effects on raw milk quality alone or combined to pasteurization heat treatment. To study its preservative effect, 1 mg l-1 of T. capitatus essential oil, characterized by GC-MS, was added to pasteurized or raw milk. The evaluation of milk quality was made by consulting samples total acidities, peroxide values and their total microbial counts, as compared to control milks. Assays were made immediately and after every 48 h of incubation at room temperature throughout 6 days. Results showed that the incorporation of T. capitatus EO to pasteurized milk was the most efficient treatment that inhibited milk deterioration. Combining pasteurization to EO incorporation into raw milk inhibited completely the contaminant bacterial growth to the second day of incubation. Moreover, until the fourth day, no statistical differences have been recorded on the total acidity of incorporated and pasteurized milk samples, while raw milk acidity exceeded 55 g of lactic acid equivalent l-1. Considering milk fat oxidation, adding T. capitatus EO to pasteurized milk has significantly retarded milk peroxide production to day 4. In conclusion, Thymus capitatus essential oil, combined to pasteurization, presents an interesting potency to act as milk stabilizer.

Abstract
This work focuses on the variability of Retama raetam (Forssk.) Webb bioactive compounds as a function of the plant cycle. The main results showed that it exhibited the highest percentage of polyunsaturated fatty acids, along with superior levels of vitamin C and total phenolic compounds (66.49%, 645.6 mg·100 g−1 FW and 23.9 mg GAE·g−1, respectively) at the vegetative stage. Instead, at the flowering and mature fruiting stages, R. raetam (Forssk.) Webb exhibited notable contents of proline (25.4 μmol·g−1 DW) and carotenoids (27.2 μg·g−1 FW), respectively. The gathered data concerning the antioxidant activity highlighted the effectiveness of the vegetative stage in comparison to the other periods. Actually, IC50 and EC50 values of the hydromethanolic extract obtained from the plant shoots at the vegetative stage were of 23, 380, 410, 1160 and 960 μg·mL−1 (DPPH• and ABTS•+ radicals scavenging activity, reducing power, chelating power and β-carotene bleaching activity, respectively). Furthermore, the four studied stages showed appreciable antibacterial capacities against human pathogens with a higher efficiency of the vegetative stage extract. Finally, the LC-DAD-ESI/MSn analysis revealed the predominance of isoflavonoids as main class of phenolic compounds and demonstrates that individual phenolic biosynthesis was clearly different as a function of plant growth. These findings highlight that reaching the optimum efficiency of R. raetam (Forssk.) Webb is closely linked to the physiological stage.

Abstract
Salinity and K+ deficiency are two environmental constraints that generally occur simultaneously under field conditions, resulting in severe limitation of plant growth and productivity. The present study aimed at investigating the effects of salinity, either separately applied or in combination with K+ deficiency, on growth, photosynthetic performance, secondary metabolites content, and related antioxidant capacity in Sulla carnosa. Seedlings were grown hydroponically under sufficient (6000 μM) or low (60 μM) K+ supply with 100 mM NaCl (C + S and D + S treatments, respectively). Either alone or combined with K+ deficiency, salinity significantly restricted the plant growth. K+ deficiency further increased salt impact on the photosynthetic activity of S. carnosa, but this species displayed mechanisms that play a role in protecting photosynthetic machinery (including non photochemical quenching and antioxidant activity). In contrast to plants subjected to salt stress alone, higher accumulation of phenolic compounds was likely related to antioxidative defence mechanism in plants grown under combined effects of two stresses. As a whole, these data suggest that K+ deficiency increases the deleterious effects of salt stress. The quantitative and qualitative alteration of phenolic composition and the enhancement of related antioxidant capacity may be of crucial significance for S. carnosa plants growing under salinity and K+ deficient conditions.

Abstract
Rhus species are known in traditional medicine for their therapeutic virtue and their extracts showed numerous important properties including antimalarial, antimicrobial, antiviral, and hypoglycemic and anticonvulsant activities. Rhus tripartitum (Ucria) is a medicinal plant widely used in Tunisia folk medicine against chronic diarrhea and gastric ulcer. This study was designed to examine in vitro and ex vivo antioxidant, anti-inflammatory and anticancer activities of four extracts of Rhus tripartitum root cortex with increasing solvent polarity (hexane, dichloromethane, methanol and water). HPLC was used to identify and quantify phenolic compounds in Rhus extract. Water extract showed the highest antioxidant activity using oxygen radical absorbance capacity (ORAC method) with 8.95 ± 0.47 µmol Trolox/mg and a cell based-assay with 0.28 ± 0.12 µmol Trolox/mg as compared to the other fractions. Moreover, methanol extract displayed the strongest anti-cancer activity against human lung carcinoma (A-549) and colon adenocarcinoma cell lines (DLD-1) with an IC50 value of 60.69 ± 2.58 and 39.83 ± 4.56 µg/ml (resazurin test) and 44.52 ± 5.96 and 55.65 ± 6.00 µg/ml (hoechst test), respectively. Besides, the highest anti-inflammatory activity, inhibiting nitric oxide (NO) release, was exhibited by dichloromethane extract with 31.5 % at 160 µg/ml in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The HPLC analysis showed that catechol and kaempferol were the major phenolics. These data suggest the richness of all fractions of Ucria root on interesting bioactive molecules with different polarity and confirm the known traditional therapeutics virtues of this species for the treatment of dysentery, diarrhea and gastric ulcer.

Abstract
INTRODUCTION Acute pericarditis is a frequent hospitalization cause. A prospective, bicentric study aimed at different goals: population description, aetiologies screening, and evaluation of the interest of a coordinated and combined management between cardiologists and internists. PATIENTS AND METHODS Between May 2005 and September 2007, all patients admitted for acute pericarditis were prospectively enrolled. Physical examination, ECG, echocardiography, biological screening were performed. Patients were asked to consult both cardiologist and internist, one month later. RESULTS Hundred and three patients were enrolled (mean age 43 years). Clinical outcome was classical in 60% of cases. ECG was typical in 59%. Troponin elevation was noted in 30% of patients. CRP was normal at diagnosis in 27% of patients, and increased significantly at first day (P=0.002). Possible cause was identified in 44 patients. In 26 patients (24.3%), precise diagnosis was performed: six cancers, one hemopathy, three connectivities, one EBV and one parvovirus B19 seroconversions, two untreated HIV patients, four inflammatory diseases, three endocrinology troubles, one oesophagitis, one dental sepsis, one amyloidosis, one acute pancreatitis, one declined dialysis indication. Eighteen de novo diagnoses (16.5%) were performed, out of them at least 12 benefited from specific management. CONCLUSION Population of patients admitted for acute pericarditis are very heterogeneous. Our co-management between internists and cardiologists aims to diagnose earlier and easier curable diseases. Long-term follow-up remains of great interest, in order to diagnose later other disorders, which remained hidden, and to follow evolution of the population.

Abstract
The medical emergency ward makes a link between outpatients and hospitalized ones, so we can study community bacterial ecology. The antibiotic susceptibility in Escherichia coli strains isolated from urinary tract infections (UTI) of patients consulting at emergency ward of our hospital in 2002 and 2004 was determined and compared with the susceptibility of the same strains isolated from UTI of hospitalized patients on the same period. The antibiotic susceptibility was performed with Microscan (Dade Behring). All bacteria were tested against the following antimicrobial agents: amoxicilline (Amx), l'amoxicilline+clavulanic acid (AMC), nalidixic acid (NA), ciprofloxacine (Cip), cotrimoxazole (SXT), nitrofurantoin (Ft). Susceptibility in E. coli strains isolated from outpatients vary from 58 to 54% for Amx, from 88 to 83% for NA, from 96 to 89% for Cip, from 82 to 79% for SXT, from 94 to 96% for Ft and remains at 60% for AMC from 2002 to 2004. Susceptibility in E. coli strains isolated from hospitalized patients vary from 52 to 47% for Amx, 55 to 53% for AMC, from 79 to 70% for NA, from 87 to 79% for Cip, from 74 to 69% for SXT, from 93 to 92% for Ft. Susceptibility in E. coli strains isolated in the community from UTI outpatients is decreasing and it becomes worrying particularly concerning the fluoroquinolones, therefore empiric treatment of pyelonephritis by fluoroquinolones must be assessed again.

Abstract
OBJECTIVE To investigate whether pregnancy accelerates HIV-1 disease progression. METHOD In two large French SEROCO and SEROGEST prospective cohorts of HIV infected patients, the progression to AIDS in 365 women with a known date of HIV-1 seroconversion was examined by comparing those who delivered after HIV infection (n = 241) with those who did not become pregnant while HIV-infected (n = 124). RESULTS The crude relative risk of developing AIDS associated with pregnancy was 0.7 [95% confidence interval (CI), 0.4-1.2]. Adjustment for age at seroconversion, the CD4+ cell percentage at entry, and the method used to date seroconversion did not modify the results (adjusted relative risk, 0.7; 95% CI 0.4-1.2). CONCLUSIONS No deleterious effect of pregnancy on progression from seroconversion to AIDS was found. This result has important implications for the counselling of HIV-infected women of child-bearing age.

Abstract
We have compared the value of different variables used in the assessment of blood loss during progressive hypovolaemia and resuscitation under general anaesthesia in anaesthetized pigs. We measured mean arterial pressure (MAP), pulmonary capillary wedge pressure (PCWP), the negative component of the systolic arterial pressure variation (delta Down) and left ventricular end-diastolic area (LVEDa) using echocardiography. Blood was progressively withdrawn (up to 35 ml kg-1 in seven steps) and then reinfused after the same pattern. Regression coefficient (r) and normalized slope (nS) of the regression relationship between each variable and amount of blood loss were determined. The difference between the withdrawal and reinfusion curves was assessed by the area between the curves. We also estimated the minimal loss of blood volume which induced significant changes in each variable compared with that under control conditions during withdrawal of blood (minWBV) and maximal loss in blood volume which induced no significant changes in a variable compared with control conditions during retransfusion (maxRBV). During haemorrhage, MAP decreased (from mean 74 (SD 9) to 31 (5) mm Hg; P < 0.001), delta Down increased (from 1.2 (1.4) to 11.4 (4.2) mm Hg; P < 0.001), PCWP decreased (from 6.2 (2.1) to 0.3 (1.0) mm Hg; P < 0.001) and LVEDa decreased (from 13.8 (2.0) to 5.1 (2.0) cm2; P < 0.01). The highest r values were obtained with MAP and LVEDa, and the highest nS value with delta Down. The least difference between withdrawal and reinfusion was with LVEDa, the lowest values of minWBV were with PCWP and LVEDa, and the highest value of maxRBV was obtained with PCWP. During progressive haemorrhage under general anaesthesia, LVEDa was an accurate variable for assessment of blood volume loss, delta Down contributed no further information compared with MAP, and PCWP was the most reliable variable for assessing return to baseline blood volume.

Abstract
This prospective study was conducted to describe the signs on transesophageal echocardiography (TEE) associated with traumatic aortic injury (TAI). Twenty-eight patients with TAI underwent TEE, and they were compared with a control group of 30 thoracic trauma patients without aortic injury. The TEE signs were classified as direct or indirect signs, and the quality of imaging was assessed. Patients' TEE images were compared with their anatomic lesions. The direct signs were thick stripes (n=19), false aneurysm (n=7), aortic dissection (n=6), free-edge intimal flap (n=15), aortic wall hematoma (n=2), fusiform aneurysm (n=13), and complete aortic obstruction (n=2). The indirect signs included minor increases in aortic diameter (n=7), impairment of the aortic Doppler color flow (n= 18), and an increase of aorta-probe distance, indicating hemomediastinum (n=23). TEE allowed diagnosis of recently described limited intimal lesions frequently missed by other conventional methods, and permitted rapid diagnosis of complete rupture in which fast degeneration means that more time-consuming methods are not practicable. Significant blurring of the aortic outline was noted in 20% of cases and intraluminal artifacts were observed in 36% of cases, but neither sign impaired accurate diagnosis of TAI. The echocardiographic signs of aortic injury are complex and may be confined to a short section of the aorta. Therefore, examination by a physician highly trained in echocardiography is necessary in such cases.

Abstract
HIV-infected women have a high prevalence of abnormal Papanicolaou smears and cervical intraepithelial neoplasia. A multiparametric analysis of epidemiological and behavioural risk factors has been performed in a cohort of 204 HIV-infected women in an outpatient clinic with the aim to investigate risk factors associated with squamous intraepithelial lesions (SIL) in HIV-seropositive women. The prevalence of SIL in the study population was 35.7%. Univariate and multivariate analysis of demographic, behavioural and immunological variables only identified cigarette smoking > 20/day and CD4+ cell counts < or = 200 x 10(6)/L as risk factors significantly associated with SIL in the study population. We found no epidemiological/behavioural risk factors specifically associated with SIL in HIV-infected women as compared with the general population. The results suggest that the high prevalence of SIL in HIV disease is related to acquired immune deficiency in HIV-seropositive women.

Abstract
The purpose of this study, based on data from the register of ectopic pregnancy in Auvergne (centre of France), is to identify risk factors of recurrence of ectopic pregnancy (EP). The social characteristics, gynaecological, surgical and reproductive history and conditions of the conception of 96 women with a previous EP were compared to those for 566 women without previous EP. Risk factors associated with the management of the first EP could not be analysed with the data available. Several factors increased the risk of recurrence: previous proved or suspected salpingitis (OR = 3.6), maternal smoking (OR = 1.7 to 2.0 according to the consumption level), maternal age greater than 30 (OR = 2.0), and previous recurrent spontaneous abortions (SA) among childless women (OR = 3.4 to 11.9 according to the number of SA). The last of these factors may reflect another unknown risk factors common to recurrent SA and recurrent EP (for example hormonal or karyotype factors). Previous use of intra uterine device is associated with a decrease in the risk of recurrence of EP (OR = 0.27), but this contraceptive method should be considered as an indicator of good fertility rather than as a protective factor for EP recurrence.

Abstract
The extent of clandestine prostitution in Djibouti is difficult to evaluate. Due to the secrecy of the prostitutes and often their low level of education, the follow-up of these patients is also difficult. A sexually transmitted disease clinic specialized in the treatment of prostitutes and their customers has been established in Djibouti since 1963. We tried to evaluate the available data on the clandestine prostitutes attendance at the center. The population was young with a mean age of 23 years. Fifty percent had children and 60% were divorced or separated. Ninety-one percent were Ethiopian and 73% lived in the same district of the city of Djibouti. Almost half of them were HIV positive. The duration of residence in Djibouti before the first visit to the clinic varied widely with a median of 12 months. However, the total duration of prostitution before the first visit was shorter with a median of 3 months. The complaint at the first visit was most often minor. Among the prostitutes who first came to the center in 1993, half of them came only once. The overall duration of follow-up was 8 months, for an average of 3.7 visits per patient. Alternatively, 20 patients had more than 10 consultations and this represented one third of the consultations given to previous patients. This last group is the only one which tended to respect the monthly visits proposed to each patient at the first consultation. The other patients seemed to come only when they felt ill. The routine statistical activities which separately counted the new and previous patients gave an optimistic but faulty impression: these showed an increase in the total number of patients and also an increase in the percentage of previous patients visiting (from 42 to 69% between 1988 and 1994). It is difficult to evaluate the follow-up of such a mobile population. The few patients known for their fidelity contrasted with the fact that half of the patients had visited the center only once. This low frequency of visitation could be due to either the management of the center or to the lack of proximity of the contacts within the districts.

Abstract
BACKGROUND Left ventricular fractional area changes (FAC) can be derived from transesophageal echocardiography using an automated border detection system. However, FAC has not yet been compared to left ventricular ejection fraction (EF) evaluated by a reference technique. The aim of this study was to correlate transesophageal echocardiography automated FAC to EF derived from radionuclide angiography to obtain a quantifying method of global left ventricular systolic function at the bedside. METHODS Ten critically ill patients, whose lungs were mechanically ventilated, were included in this prospective study. Patients were scheduled for radionuclide EF evaluation when at least 75% of the endocardium was clearly visualized on transesophageal echocardiography. Patients with esophageal pathology or cardiac dysrhythmia were excluded. Ejection fraction derived from radionuclide angiography was measured using technetium 99m. Echocardiographic data were obtained using an ultrasound system with automated border capabilities. Simultaneous measurements of left ventricular EF and FAC were obtained for each patient, both before and after starting a dobutamine intravenous infusion to modify left ventricular contractility. RESULTS Mean values for radionuclide EF and transesophageal echocardiography FAC were, respectively: 55% +/- 19% (range 19-89%) and 46% +/- 18% (range 17-80%). Left ventricular EF and FAC were significantly correlated (r = 0.85, SEE = 9.6%). Variations of EF and FAC, induced by dobutamine, were also correlated (r = 0.70, SEE = 4.9%). CONCLUSIONS Fractional area changes determined by transesophageal echocardiography using automated border detection correlate well with radionuclide EF and may be used at the bedside to quantify left ventricular function in selected intensive care unit patients.

Abstract
BACKGROUND The mechanism of brain death-induced myocardial dysfunction remains debatable. Hypocalcemia is known to induce reversible myocardial dysfunction. However, the incidence of hypocalcemia and its effect on myocardial function during brain death is unknown. METHODS In 54 consecutive brain-dead patients, we measured plasma total and ionized calcium concentrations, QT and corrected QT intervals, and left ventricular ejection fraction area (LVEFa), using transesophageal echocardiography. RESULTS 49 (91%) of brain-dead patients had a decrease in total plasma total calcium concentration but only 19 (35%) had a decrease in plasma ionized calcium. Corrected total plasma calcium failed to predict ionized calcium concentration and QT intervals were not significantly different in normo and hypocalcemic patients. The LVEFa was not significantly different between normo and hypocalcemic patients (53 +/- 13 versus 50 +/- 20%), and no correlation was found between LVEFa and ionized calcium (R = 0.02, NS). Hypocalcemic patients required greater doses of dopamine (8.2 +/- 5.2 versus 5.0 +/- 3.4 micrograms.kg-.min-1, p < 0.02) to maintain arterial pressure. Hypocalcemia was associated with a higher volume loading and a lower plasma protide concentration which reflected hemodilution. CONCLUSION A decrease in plasma ionized calcium is not frequent, rarely severe, and probably not the main mechanism of myocardial dysfunction in brain-dead patients. Hypocalcemic patients required higher doses of dopamine, suggesting a decrease in systemic resistance. Only direct measurement of ionized calcium can assess plasma calcium ion status in brain-dead patients.

Abstract
BACKGROUND Brain death may induce myocardial dysfunction, the mechanisms of which are not yet fully understood. Circulating cardiac troponin T is considered a highly sensitive and specific marker of myocardial cell injury. METHODS AND RESULTS We prospectively measured circulating cardiac troponin T in 100 brain-dead patients and measured the left ventricular ejection fraction area (LVEFa), using transesophageal echocardiography. Sixty-one patients had normal LVEFa, 25 had moderate decrease in LVEFa (30% to 50%), and 14 had severe decrease in LVEFa (< or = 30%). Circulating cardiac troponin T concentrations were significantly higher (1.68 +/- 1.03 micrograms/L-1, P < .01) in patients with a severe decrease in LVEFa than in the two other groups (0.42 +/- 0.43 and 0.12 +/- 0.16 microgram/L-1, respectively), and there was a significant correlation between LVEFa and cardiac troponin T concentration (p = -0.59, P < .0001). An elevated circulating cardiac troponin T concentration (> or = 0.5 microgram/L-1) was more accurate (sensitivity, 1.00; specificity, 0.84) in predicting a severe decrease in LVEFa than an elevated CKMB value or an increased CKMB/CK ratio. CONCLUSIONS An elevated circulating cardiac troponin T was associated with a severe decrease in LVEFa in brain-dead patients, suggesting that severe and potentially irreversible myocardial cell damage occurred. In contrast, CKMB determination was not useful. Since the quality of the donor's heart is considered an important prognosis factor in heart transplantation, the determination of circulating cardiac troponin T concentration could be useful to the heart transplantation team.

Abstract
Systemic air embolism has been frequently reported after penetrating thoracic trauma. In blunt thoracic trauma, systemic air embolism has been rarely diagnosed, and then only after an invasive procedure such as thoracotomy. Transesophageal echocardiography has been recently introduced for the early assessment of trauma patients and is considered a sensitive noninvasive procedure to diagnose air embolism. We report three cases of systemic air embolism in patients with pulmonary contusion secondary to a blunt thoracic trauma requiring controlled ventilation. Transesophageal echocardiography was performed for evaluation of hemodynamic instability, and it showed air bubbles in the left atrium and left ventricle during the insufflation phase, which disappeared during apnea. A decrease in airway pressure (release of PEEP, low tidal volume, high frequency jet ventilation) significantly reduced the systemic air embolism. We concluded that systemic air embolism can occur after blunt thoracic trauma, and transesophageal echocardiography enables a rapid and accurate diagnosis that may be useful for therapeutic management.

Abstract
Hypophosphataemia is known to induce reversible myocardial dysfunction, but the incidence of hypophosphataemia and its effect on myocardial function during brain death are unknown. In 90 consecutive brain-dead patients, we measured plasma concentrations of phosphate and left ventricular ejection fraction area (LVEFa), using transoesophageal echocardiography. In 15 severely hypophosphataemic (< 0.40 mmol litre-1), consecutive, brain-dead patients, haemodynamic status, LVEFa, and oxygen delivery and consumption were assessed before and after phosphorus loading (0.30 mmol kg-1). In 10 other brain-dead patients, urine elimination of phosphates was measured. Only 30 (33%) brain-dead patients had normal plasma phosphate concentrations, 22 (24%) had mild hypophosphataemia (0.40-0.80 mmol litre-1) and 38 (42%) had severe hypophosphataemia (< 0.40 mmol litre-1). There were no significant differences in LVEFa between these three groups (mean 53 (SD 16), 55 (12) and 51 (17)%, respectively) and no significant correlation between LVEFa and plasma phosphate concentration (r = 0.04). In 15 severely hypophosphataemic patients, phosphorus loading increased plasma phosphate concentration from 0.30 (0.10) to 1.06 (0.41) mmol litre-1, but did not modify haemodynamic status, LVEFa or oxygen delivery and consumption. In 10 other patients, urine phosphorus elimination was 16.8 (23.3) mmol/24 h while plasma phosphate concentration was at its highest level (0.80 (0.37) mmol litre-1), and only one of these patient had a slightly elevated phosphaturia. In conclusion, hypophosphataemia frequently occurs after brain death but has no significant cardiovascular consequences, suggesting that it is related to intracellular transfer and not phosphorus depletion.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In an open study of 26 patients undergoing abdominal aortic surgery, the effects of rocuronium 0.6 mg kg-1 (eight patients) and 0.9 mg kg-1 (nine patients) were compared with those of pancuronium 0.085 mg kg-1 (eight patients) on haemodynamic parameters and transoesophageal echocardiography. The anaesthetic technique was based on a benzodiazepine and low dose fentanyl (6 micrograms kg-1). Pancuronium was associated with a significant increase in mean arterial pressure, end-diastolic area and heart rate, none of which were seen after rocuronium at either dose level.

Abstract
As suggested by experimental studies, systolic pressure variation (SPV), the difference between maximum and minimum values of systolic blood pressure after a single positive pressure breath, may be a fair indicator of left ventricular preload. SPV was quantified in 21 patients who had undergone abdominal aortic surgery and were sedated under mechanical ventilation. The aim of the study was to assess the ability of this parameter to qualitatively estimate left ventricular preload measured using transesophageal echocardiography. All patients had preoperative radionuclide ejection fraction > 45%. Postoperative mechanical ventilatory patterns were the same for all patients: tidal volume = 10 mL/kg; respiratory frequency = 12-14 breaths/min; and zero end-expiratory pressure mode. Left ventricular dimensions at end-diastole correlated well with the magnitude of both SPV (r = 0.80) and its delta down (dDown) component (i.e., the degree by which systolic pressure decreases with each mechanical breath) (r = 0.83). Once the first measurement was completed, volume loading with two increments of 250 mL of human albumin 5% was performed in all but three patients. Each volume loading step caused a significant increase in the end-diastolic area (EDa) index (7.0 +/- 1.6 to 8.5 +/- 1.6 cm2/m2) and cardiac index (CI) (3.1 +/- 0.9 to 4.1 +/- 0.9 L.min-1 x m-2) and a concomitant significant decrease in the SPV (8.6 +/- 4.5 to 6.1 +/- 3.7 mm Hg) and its dDown component (5.9 +/- 4.1 to 2.9 +/- 2 mm Hg).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The benefits of transoesophageal echocardiography (TOE) were assessed prospectively in intensive care patients. The doctors carrying out TOE were not the same as those who ordered it. TOE was performed in 32 patients, all of whom but one were intubated and artificially ventilated, to elucidate the cause of circulatory shock, or to search for valvular vegetations or an intracardiac mass. TOE confirmed the diagnosis previously obtained with pulmonary arterial catheterization (10 patients), transthoracic echocardiography (3 patients) or ventriculography (1 patient) in 54% of cases. In 28% of cases, TOE invalidated the suspected diagnosis, and, in the remaining 28% of patients, TOE invalidated provided a previously unsuspected diagnosis. TOE was particularly useful in confirming the presence of valvular vegetations, endocarditis, or intracardiac thrombi, and to assess left ventricular function and preload in patients in shock. Like others, this study confirms the benefits of TOE in the intensive care setting.

Abstract
PURPOSE To prospectively quantify the degree of accuracy of portable chest x-ray film examination in the detection of postoperative lung consolidations. STUDY Nineteen patients had a chest x-ray film and computed tomography (CT) scan the day before and 48 h following elective abdominal aortic replacement. RESULTS The diagnosis of lung consolidations by x-ray film examination showed sensitivity of between 0.33 and 1.00, depending on the lung zone considered (lower at the lung bases). Specificity always was greater than 0.79. Radiologic lung volume decreased 16 percent postoperatively (p < 0.01) on average and noninflated parenchyma increased by a factor of 3 (p < 0.0001). Postoperatively, PaO2 correlated with the amount of condensed lung by CT scan (p < 0.002). CONCLUSION In postoperative conditions, x-ray film examination is a method which presents good specificity but poor sensitivity in the diagnosis of lung consolidations.

Abstract
Preoperative normovolemic hemodilution (PNH) has been proposed for patients scheduled to undergo aortic surgery. Coronary artery disease is frequent in these patients. The aim of the study was to assess the effect of PNH on hemodynamics and segmental wall motion (SWM) evaluated by transesophageal echocardiography in such patients. Twenty patients with coronary artery disease were allocated randomly to either PNH or no PNH; PNH was performed after anesthetic induction using dextran 60,000. Patients were operated on under general anesthesia and monitored intraoperatively with electrocardiographic lead CM5, radial and pulmonary artery catheters, and transesophageal echocardiography positioned to obtain a short-axis view. Hemodynamic and transesophageal echocardiographic data were collected after anesthetic induction and after PNH, before and 5 min after aortic clamping, after unclamping, and at the end of surgery. Aortic clamping induced a significant increase in systemic vascular resistance and arteriovenous difference in oxygen and a decrease in cardiac index (P < 0.05), but the effect of aortic clamping was inversely related to hemodilution. The SWM score (graded from 1 = normal to 5 = dyskinesia) was significantly increased after aortic clamping, mainly in the anterior segment (P < 0.05). Four patients in the control (no PNH) group and one in the PNH group developed new SWM abnormalities indicative of myocardial ischemia during surgery (P = NS). This study suggests that PNH may improve hemodynamic tolerance to aortic clamping in patients with coronary artery disease. The observed changes in SWM indicate that PNH may not worsen myocardial ischemia in patients scheduled to undergo aortic surgery.

Abstract
Patients scheduled for vascular surgery are considered at risk for perioperative cardiac complications. Choice of anesthetic in such patients is guided by a desire not to adversely affect myocardial function. On the basis of data from laboratory studies, thoracic epidural anesthesia (TEA) has been advocated to prevent myocardial ischemia. The aim of this study was to assess whether TEA combined with general anesthesia has any effect on segmental wall motion (SWM) monitored by transesophageal echocardiography in these patients. Patients received alfentanil, midazolam, vecuronium, and 50% N2O in oxygen, and ventilation was controlled after orotracheal intubation; 12.5 mL of 2% lidocaine HCl was injected through an epidural catheter placed at T6-7 or T7-8. Hemodynamic measurements and transesophageal echocardiographic recordings were obtained before and 10, 20, 30, 40, and 60 min after lidocaine injection. Segmental wall motion was graded a posteriori by two independent experts on a predetermined scale (from 1 = normal to 5 = dyskinesia). A decrease greater than or equal to 2 grades was considered an SWM abnormality indicative of ischemia. Thoracic epidural anesthesia induced a decrease in systemic arterial blood pressure, heart rate, and cardiac index. The SWM score decreased slightly from 1.34 +/- 0.68 to 1.27 +/- 0.64 (mean +/- SD) (at 10 and 20 min, respectively) (P less than 0.05). Patients were a posteriori analyzed according to whether they had documented coronary artery disease or not. The SWM score before TEA was significantly higher in patients with documented coronary artery disease (1.51 +/- 0.88 vs 1.17 +/- 0.51, respectively; P less than 0.05) and did not change significantly after TEA.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The effect of oral premedication with 300 micrograms of clonidine on systemic arterial pressure, heart rate, and plasma norepinephrine levels was assessed in a double-blinded, placebo-controlled study conducted in 29 patients subjected to carotid artery surgery (CAS). Anesthesia was induced with thiopental, 6 mg/kg, and alfentanil, 0.05 mg/kg, and maintained with alfentanil and 0.6% isoflurane in 50% N20/O2. The study was divided into five periods as follows: (1) anesthesia to start of surgery; (2) surgery to carotid artery clamping; (3) carotid artery clamping to unclamping; (4) carotid artery unclamping to the end of surgery; and (5) the first 4 postoperative hours in the recovery room. In the clonidine group (n = 14), plasma norepinephrine concentrations were significantly lower before induction of anesthesia and during the operative period. Heart rate and systemic arterial pressure were lower (P less than 0.01) in the clonidine group at 3 different time intervals (control, carotid clamping, carotid unclamping). However, during each of the previously defined periods, the variability of heart rate and systemic arterial pressure, assessed by the coefficient of variation, was not different between the two groups. The lability of these hemodynamic parameters, expressed as the percentage of values, which increased or decreased more than 20% of control values during the corresponding period, was also comparable between the two groups. The number of patients who experienced at least one episode of hypertension (systolic arterial pressure greater than 180 mm Hg), hypotension (systolic arterial pressure less than 100 mm Hg), or bradycardia less than 45 beats/min was not different between the two groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Epidural clonidine produces postoperative analgesia in patients and potentiates opioid analgesia in animals. The aim of the current study was to assess the effect of epidural clonidine on the plasma concentrations and analgesic effect of fentanyl after epidural administration. Twenty ASA physical status 2 or 3 patients recovering from abdominal surgery were allocated randomly to receive either epidural fentanyl (100 micrograms in 10 ml isotonic saline; EF group) or epidural fentanyl (same dose) plus epidural clonidine (150 micrograms; EF + C group) in isotonic saline solution. Analgesia was assessed over a period of 12 h after epidural injection. Venous samples were obtained until 360 min after epidural injection for radioimmunoassay determination of plasma fentanyl concentration. Onset of analgesia was similar in the two groups of patients (13 +/- 6 and 13 +/- 3 min, respectively, after injection), but duration was more than doubled in the patients receiving clonidine (543 +/- 183 vs. 250 +/- 64 min). Peak plasma fentanyl concentrations (Fmax) and the time to reach Cmax (Tmax) were comparable in the two groups (0.29 +/- 0.15 ng.ml-1 at 16.2 +/- 14.8 min in the EF group and 0.27 +/- 0.11 ng.ml-1 at 8.3 +/- 5.5 min in the EF + C group), as were plasma concentrations at each definite time of measurement. Drowsiness and hypotension were noticed in the EF + C group. Thus, epidural clonidine appears to prolong epidural fentanyl analgesia without affecting its plasma concentration.

Abstract
This case report describes a patient with massive pulmonary embolism and acute circulatory failure in whom transesophageal echocardiography permitted the diagnosis of thrombi in the main pulmonary truncus and in the right branch and guided intraoperatively the surgical embolectomy performed under simple venous inflow occlusion because of a contraindication to heparin administration. Transesophageal echocardiography seems to be a very helpful technique to diagnose promptly massive pulmonary embolism and a very useful tool at the time of operation to guide the embolectomy.

Abstract
This study is a retrospective analysis of 303 consecutive spinal anaesthesia performed in orthopaedic patients of a University Hospital between January and December 1990. Failure of spinal anaesthesia was defined as the requirement for general anaesthesia to perform surgery. The parameters studied as possible risk factors of failure were patients demographics, local anaesthetic agents and solutions and techniques of spinal anaesthesia (single injection versus continuous spinal anaesthesia). Failures were related to inadequate or incomplete extension of sensory blockade or to difficulties to perform spinal injection. Continuous spinal anaesthesia was performed in 209 patients mostly with 0.5% isobaric bupivacaine, while 94 patients received a single injection of either hyperbaric 0.5% tetracaine with adrenaline or 0.5% bupivacaine or 5% lidocaine. Failures occurred in 6.3% of the cases but were significantly less frequent with continuous spinal anaesthesia (4.8%) than with the conventional technique (9.6%). The incidence of failure was higher with hyperbaric tetracaine (11.1%) confirming its poor reliability. Inadequate extension of the anaesthetic block was the main cause of failure whatever the spinal anaesthetic technique. These results point out the reliability of continuous spinal anaesthesia but problems may occasionally occur due to spinal catheter misplacement.

Abstract
This study was designed to determine whether clonidine has analgesic properties, decreases the minimum alveolar concentration of inhalational anesthetics, or affects the quality and the duration of spinal anesthesia with bupivacaine. The comparative effects of oral and subarachnoid clonidine on spinal anesthesia with bupivacaine were studied in 36 patients scheduled for orthopedic surgery. Patients were allocated randomly into four groups to receive either oral diazepam (10 mg in Groups I and II) or oral clonidine (150 micrograms and 300 micrograms in Groups III and IV, respectively), as premedication. Spinal anesthesia was performed with 15 mg hyperbaric bupivacaine 0.5% plus either 1 ml isotonic saline in Groups I, III, and IV, or 150 micrograms clonidine in Group II. Subarachnoid but not oral clonidine significantly prolonged the duration of sensory block (time for regression to L2 was 157 +/- 21 minutes in Group I and 267 +/- 75 minutes in Group II) and the duration of motor block (duration of Grade 3 motor block--Bromage scale--was 103 +/- 20 minutes in Group I and 175 +/- 68 minutes in Group II). Only the subarachnoid administration of clonidine achieves adequate concentrations to significantly increase the duration of spinal anesthesia.

Abstract
To compare the analgesic efficacy and plasma concentration of intramuscular (IM) versus epidural (EP) clonidine, 20 patients recovering from orthopedic or perineal surgery were randomly divided into two groups of ten. Clonidine (2 micrograms/kg) was administered epidurally in group 1 and intramuscularly in group 2. Analgesia was assessed using a visual analog scale (VAS) over a period of 6 h following clonidine administration. Venous blood samples were obtained at specific intervals for radioimmunoassay determination of plasma clonidine concentrations. The maximum reduction in VAS pain score was 78.5 +/- 20.6% in the EP group and 68.1 +/- 31.5% in the IM group (NS). Onset of analgesia was similar (within 15 min of injection), but duration tended to be longer after epidural than intramuscular administration (208 +/- 87 min vs. 168 +/- 95 min, mean +/- SD, P greater than 0.05). The peak plasma clonidine concentration after EP injection was 0.82 +/- 0.22 ng/ml and 1.02 +/- 0.76 ng/ml after IM injection. Hypotension, bradycardia, and drowsiness occurred with both methods of administration. None of these effects required treatment. Thus, in postoperative patients clonidine produces similar analgesia and side effects after parenteral or EP administration.

A case is reported of a foramen ovale becoming patent during orthotopic liver transplantation (OLT). The patient had a hepatoma secondary to post-hepatitis cirrhosis. Monitoring included transesophageal echocardiography (TEE). A veno-venous shunt between the right femoral, portal and left axillary veins was used so as to maintain the venous return during portal and caval clamping. The patient's haemodynamic state remained quite stable throughout this period, and no vasoactive drug was required. Five min after graft reperfusion, pulmonary arterial pressure increased suddenly (mean PAP: 27 mmHg). TEE revealed paradoxical movements of the atrial septum. Colour coded Doppler ultrasound showed blood flowing from the right to the left atrium through a patent foramen ovale. Fifteen min later, mean PAP decreased (18 mmHg) and TEE no longer showed any flow between the two atria. Several studies have reported transient pulmonary hypertension after unclamping when the donor liver is reperfused. This could induce right ventricular failure, with transient inversion of the atrial pressure gradient, which, in turn, could result in a right-to-left shunt through a patent foramen ovale. TEE can monitor regional and overall left ventricular function as well as the atrial septum. This technique might therefore to be useful for cardiac monitoring during OLT.

Abstract
A study was carried out to find out whether dividing the dose of local anaesthetic would give a better control of the spread and duration of sensory blockade due to spinal anaesthesia. It was carried out in 34 patients (mean age 62 years) scheduled for elective limb vascular surgery. All were classed ASA 2 or 3. Sensory blockade was assessed using a fine needle, and the degree of motor blockade with Bromage's scale. This was carried out every 5 min for the first 30 min, and thereafter, every 15 min until recovery from anaesthesia was complete. In the first group of patients (n = 16), spinal anaesthesia was obtained with a 26 gauge needle, the patient lying on his side; 4 ml of 0.5% bupivacaine were injected (1 ml every 10 seconds) before putting the patient supine. In the second group (n = 18), the catheter for continuous spinal anaesthesia was set up with the patient in the same position as for the first group. Once a length of 1 cm had been introduced in the subarachnoid space, the patient was placed supine and 2 ml of 0.5% bupivacaine were injected. If 15 min later sensory blockade did not reach T10, further 0.5 ml aliquots were given every 10 min so as to obtain a level of sensory blockade between T9 and T11. Maximum extension of sensory blockade was 15.1 +/- 2.3 metamers in group 1, with an extension to T3 in 2 patients. In group 2, 12.9 +/- 3.1 mg bupivacaine anaesthetized 14.2 +/- 1.9 metamers.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A 56-year-old woman was admitted to the Emergency Department for profuse diarrhoea, associated with hypokaliemia and dehydration. A subclavian venous catheter was inserted after she had a cardiac arrest. Six days later, the subclavian and innominate veins were thrombosed. Prophylactic low molecular weight heparin was then replaced by sodium heparinate. The patient's platelet count decreased to 65 G.1-1. It was nevertheless decided to remove her villous tumour. After the operation, the patient became shocked, with worsening thrombocytopaenia (15 G.1-1). She was unresponsive to fluid replacement. Transoesophageal echocardiography (TEE) was carried out, as pulmonary arterial catheterization was considered too dangerous. A "white" thromboembolus was discovered in the right pulmonary artery. Embolectomy was successfully performed without extracorporeal circulation. Flow was completely restored in the main pulmonary artery, but only partially in the right branch. Oral anticoagulation was started postoperatively. It is concluded that TEE might be a very helpful technique to promptly diagnose acute pulmonary embolism; moreover, it could be an alternative to pulmonary angiography, especially in patients in a poor state.

Abstract
The analgesic effect of extradural clonidine was evaluated in a double-blind study. In the recovery room, following orthopaedic or perineal surgery 20 ASA I and II patients were allocated randomly to two groups. The extradural clonidine (EC) group received clonidine 2 micrograms kg-1 in isotonic saline solution 15 micrograms ml-1. The extradural saline (ES) group received the equivalent volume of plain isotonic saline solution. Pain was evaluated by a visual analogue scale (VAS) at 15-min intervals for the first 2 h and subsequently at 30-min intervals for the following 4 h. Morphine 5 mg was given s.c. when patients complained of pain after extradural saline or clonidine. In the EC group, the mean (SD) maximum pain relief was 68.2 (24.1)% of the initial VAS score, but it was only 14.7 (25.2)% in the ES group. The mean duration of analgesia, before injection of morphine, was significantly longer in the EC group (210 (87) min) compared with the ES group (45 (27) min) (P less than 0.001). Drowsiness and moderate hypotension were observed in the EC group.

Abstract
Baroreceptor (BR) reactivity was studied in 16 patients scheduled for carotid artery surgery performed under cervical epidural anesthesia with 0.375% bupivacaine (15 mL). In the first seven patients, BR reactivity was assessed by measurement of the slopes of the linear relationship between systolic arterial pressure (SAP) and the RR interval on the electrocardiogram. Alterations of blood pressure (BP) were produced using sequential intravenous (IV) doses of nitroglycerin (NTG; 100 to 200 micrograms) or phenylephrine (PHE; 100 to 200 micrograms), before and 30 minutes after epidural anesthesia. The changes in SAP and heart rate (HR) determined during the four phases of a Valsalva maneuver were evaluated in a second set of measurements before and after cervical epidural blockade. In nine additional patients, a third set of measurements studying BR reactivity after carotid clamping and unclamping was performed in order to assess the effect of carotid handling on BP control. Cervical epidural anesthesia induced moderate decreases in BP (SAP, 150 +/- 18 mmHg before cervical block, 143 +/- 27 mmHg after cervical block, P less than 0.05) and HR (RR, 812 +/- 120 ms before cervical block, 938 +/- 130 ms after cervical block, P less than 0.05). Cervical epidural anesthesia depressed BR reactivity during deactivation as assessed by the decrease in the BR slope after PHE injection (6.6 +/- 4.4 ms/mmHg before cervical block v 2.5 +/- 1.8 ms/mmHg after cervical block, P less than 0.01) and activation as assessed by the changes in SAP and HR during phases II and IV of the Valsalva maneuver.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In order to assess the effect of spinal clonidine on tourniquet pain, 30 patients scheduled to undergo orthopaedic surgery under spinal anaesthesia were allocated randomly to two groups. Patients in group I (n = 15) received 0.5% isobaric bupivacaine 15 mg plus isotonic saline 1 ml. Patients in group II (n = 15) received 0.5% bupivacaine 15 mg plus clonidine 1 ml (150 micrograms). Sensory block was evaluated by pinprick and motor block with Bromage's scale. The presence of clonidine significantly prolonged the duration of sensory and motor block. Three patients in group I, but none in group II, experienced tourniquet pain. Hypotension and bradycardia were not worsened by spinal clonidine. The use of clonidine may be a useful technique to augment bupivacaine spinal block.

Abstract
The effect of lumbar epidural anesthesia on myocardial wall motion was compared in two groups of patients using precordial two-dimensional echocardiography (2DE). All patients were scheduled to undergo lower abdominal or peripheral surgery. Group 1 included five healthy ASA PS 1 subjects and group 2 included 10 patients with coronary artery disease (CAD). In all patients 12.5 ml of 2% lidocaine HCl was injected into the lumbar epidural space, and systolic and diastolic blood pressures, and heart rate were continuously monitored. 2DE evaluation was performed before and at 10, 20, 30, and 60 min (T10-T60) after epidural lidocaine injection. The left ventricular wall was divided into 16 segments for parasternal long-axis, short-axis and apical four-chamber views. The wall motion of each segment was graded on a scale from 1 (dyskinesia) to 6 (hyperkinesia), with 5 representing normal motion. A decrease in segmental wall motion greater than or equal to 2 grades was considered indicative of ischemia. Plasma lidocaine and catecholamine levels were measured before and 10, 20, and 60 min after epidural lidocaine injection. Peak plasma lidocaine levels in groups 1 and 2 were 2.79 +/- 1.06 micrograms/ml (mean +/- SD) and 2.58 +/- 1.48 micrograms/ml at 10 min, respectively (NS). Plasma epinephrine and norepinephrine levels were unchanged from baseline. Systolic pressures decreased significantly in group 2 from T10 to T60. Diastolic pressure decreased significantly in the same group from T20 to T60, and in group 1 only at T10. Mean arterial pressure decreased significantly in both groups at T30, without change in heart rate.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The effect of clonidine, an alpha 2 agonist, on sensory and motor blockade during spinal anesthesia was studied in 44 ASA physical status I II patients scheduled for orthopedic surgery. The patients were randomly allocated into three groups given 15 mg of 0.5% hyperbaric tetracaine (HT), within group I (N = 14) 1 ml isotonic saline, in group II (N = 15) 0.5 ml saline solution and 0.5 ml clonidine (75 micrograms), and in group III (N = 15) 1 ml clonidine (150 micrograms). Sensory blockade (SB) was evaluated by pinprick and motor blockade (MB) according to Bromage's scale. The level of SB was comparable in the three groups but the duration was different. The 75 micrograms clonidine was associated with 25% prolongation of SB at L2 and 29% prolongation of grade 3 MB Clonidine 150 micrograms prolonged the time of SB at L2 by 72% and grade 3 MB by 96%. Colloid infusion and the decrease in diastolic blood pressure were significantly greater in the clonidine 150 micrograms group compared to group I. A dose related prolongation of spinal anesthesia is demonstrated with clonidine.
