FUNDAMENTO: A sedação durante a cineangiocoronariografia tem sido pouco estudada e saber qual é a melhor droga para sedar esses pacientes é um questionamento importante. OBJETIVO: Avaliar a qualidade da sedação e os efeitos sobre a freqüência cardíaca (FC) e a pressão arterial (PA) do midazolam e do diazepam, associados ou não a clonidina, em pacientes com suspeita de doença coronariana. MÉTODOS: Foi desenvolvido ensaio clínico prospectivo, duplo-cego, randomizado, controlado, com 160 pacientes divididos em cinco grupos de 32 pacientes cada, de acordo com o fármaco utilizado: grupo C (clonidina 0,5 µg/kg); grupo M (midazolam 40 µg/kg); grupo MC (associação de midazolam 40 µg/kg e clonidina 0,5 µg/kg); grupo D (diazepam 40 µg.kg); e grupo DC (associação de diazepam 40 µg/kg e clonidina 0,5 µg/kg). A sedação foi avaliada com base na escala de Ramsay e no consumo de meperidina 0,04 mg.kg-1. A PA invasiva, a FC e o escore de sedação foram analisados a cada cinco minutos em quatro diferentes momentos. RESULTADOS: Os pacientes que utilizaram midazolam apresentaram maiores escores de sedação e variação da FC e da PA (p < 0,05). Os que utilizaram diazepam ou clonidina tiveram menores escores de sedação e mais satisfatórios para a realização do exame e apresentaram menor variação da PA e da FC (p > 0,05). CONCLUSÃO: O midazolam foi associado a maior efeito sedativo e cardiovascular enquanto o diazepam causou menor efeito sedativo e cardiovascular. A clonidina e o diazepam tiveram efeitos semelhantes na PA, na FC e na sedação. BACKGROUND: Sedation during coronary angiography has been rarely studied, and it is important to know which drug is the best to sedate these patients. OBJECTIVE: To evaluate the quality of sedation and the effects of midazolam and diazepam alone or combined with clonidine on the heart rate (HR) and blood pressure (BP) of patients with suspected coronary artery disease. METHODS: This is a controlled, randomized, double-blind, prospective clinical study of 160 patients divided into five groups of 32 patients each, according to the drug used: group C (clonidine 0.5 µg/kg); group M (midazolam 40 µg/kg); group MC (combination of midazolam 40 µg/kg and clonidine 0.5 µg/kg); group D (diazepam 40 µg/kg); and group DC (combination of diazepam 40 µg/kg and clonidine 0.5 µg/kg). Sedation was evaluated based on the Ramsay scale and on the use of meperidine 0.04 mg.kg-1. Invasive BP monitoring, HR and the sedation score were analyzed every five minutes at four different time points. RESULTS: Patients who received midazolam presented higher sedation scores as well as HR and BP variation (p < 0.05). Those who received diazepam or clonidine had lower sedation scores, which were more satisfactory for the performance of the procedure, and presented a lower BP and HR variation (p > 0.05). CONCLUSION: Midazolam was associated with a greater sedative and cardiovascular effect, whereas for diazepam these effects were less intense. Clonidine and diazepam had similar effects on BP, HR and sedation.

Métodos: Foi desenvolvido ensaio clinico prospectivo, duplo cego, randomizado, controlado, com 160 pacientes. Estes apresentavam teste ergometrico ou cintilografia positivos para isquemia miocardica e foram submetidos a cineangiocoronariografias diagnosticas eletivas, divididos em cinco grupos de 32 pacientes cada, de acordo com o farmaco utilizado: grupo C (clonidina 0,5 Êg.kg-1); grupo M (midazolam 40 Êg.kg-1); grupo MC (associacao do midazolam 40 Êg.kg-1 e da clonidina 0,5 Êg.kg-1); grupo D (diazepam 40 Êg.kg-1); grupo DC (associacao do diazepam 40 Êg.kg-1 e da clonidina 0,5 Êg.kg-1). A sedacao foi avaliada com base na escala de Ramsay e no consumo de meperidina (0,04 mg.kg-1) que foi utilizada nos pacientes que apresentaram agitacao ou ansiedade durante o procedimento. A PA invasiva, a FC e o escore de sedacao, foram analisados a cada 5 minutos em 4 diferentes momentos: M1 - inicio do exame; M2 - 5 minutos apos o inicio do exame; M3 - metade do tempo do exame e M4 - final do exame. Resultados: Os grupos foram homogeneos com relacao a PA, FC e sedacao no momento controle (M1). Os pacientes que utilizaram o midazolam apresentaram maiores escores de sedacao e variacao da FC e PA (p0,05). A associacao com a clonidina potencializou de forma mais precoce e acentuada os efeitos sedativos do midazolam em relacao ao diazepam (p0,10)... Background to evaluate the effects of midazolam, diazepam and associations with clonidine on heart rate (HR), blood pressure (BP) as well as its sedative effect on patients submitted to coronary angiography. Methods A randomized, controlled and double blind, prospective clinical trial was conducted on 160 patients submitted to an elective coronary angiography. All of them have ergometric test or miocardic cintilography positive to ischemia. They were divided into five groups with 32 patients each: C group (clonidine 0,5 ìg.kg-1); M group (midazolam 40 ìg.kg-1); DC group (midazolam 40 ìg.kg-1 and clonidine 0,5 ìg/kg associated); D group (diazepam 40 ìg/kg); DC group (diazepam 40 ìg/kg and clonidine 0,5 ìg.kg-1 associated). Sedation was evaluated based on the Ramsay Scale. Administration of a 0,04 mg.kg-1 dose of meperidine was given to the patients who were agitated or anxious during the procedure. The invasive BP, HR and sedation score based on Ramsay Scale were analyzed every five minutes and four different intervals were considered for the assessment: M1- at the start of the test; M2 5 minutes after the start of the test; M3 half time of the test; M4 at the end of the test. Results The groups were homogeneous in relation the BP, HR and sedation in the control moment (M1) and there was no difference regarding the weight, age and sex. The patients that used midazolam presented deeper sedation score and HR and BP variability (p0,10) Conclusions The midazolam presented higher and deeper sedative and cardiovascular effect...

- Abstract
Background and Objectives: Sympathectomy is one of the therapies used in the treatment of chronic obstructive arterial disease (COAD). Although not considered as first-line strategy, it should be considered in the management of pain difficult to control. This clinical case describes the evolution of a patient with inoperable COAD who responded properly to the lumbar sympathetic block., Case Report: A female patient, afro-descendant, 69 years old, ASA II, admitted to the algology service due to refractory ischemic pain in the lower limbs. The patient had undergone several surgical procedures and conservative treatments without success. Vascular surgery considered the case as out of therapeutic possibility, unless limb amputation. At that time, sympathectomy was indicated. After admission to the operating room, the patient was monitored, positioned and sedated. The blockade was performed with the aid of radioscopy, bilaterally, at L2-L3-L4 right and L3 left levels. On the right side, at each level cited, 3mL of absolute alcohol with 0.25% bupivacaine were injected without vasoconstrictor, and on the left side only local anesthetic. The procedure was performed uneventfully. The patient was discharged with complete remission of the pain., Conclusion: Neurolitic block of the lumbar sympathetic chain is an effective and safe treatment option for pain control in patients with critical limb ischemia patients in whom the only possible intervention would be limb amputation., (Copyright © 2015 Sociedade Brasileira de Anestesiologia.

- Abstract
Background: Sedation for heart catheterization has been a cause for concern. Benzodiazepines, alpha-2 adrenergic agonists and opioids are used for this purpose. However, each drug has advantages and disadvantages., Objective: To evaluate the efficacy of sufentanil and clonidine as sedative in patients undergoing heart catheterization, observing their impact on hemodynamic and respiratory parameters, the presence of side effects and satisfaction of the patient and interventional cardiologist with the examination., Methods: This is a prospective, double-blind, randomized and controlled clinical trial involving 60 patients who received 0.1 µg/kg of sufentanil or 0.5 µg/kg of clonidine before heart catheterization. The score of sedation according to the Ramsay scale, the need for use of midazolam, side effects and hemodynamic and respiratory parameters were recorded, with the data being analyzed at 06 different moments., Results: The behavior of blood pressure, heart rate and respiratory rate was similar in both groups, but, at moment 2, the patients in the sufentanil group (Group S) had a lower sedation score on the Ramsay scale, and the peripheral oxyhemoglobin saturation was lower than in the clonidine group (Group C) at time 6. Patients in Group S had higher incidence of nausea and vomiting after surgery than patients in Group C. Patient satisfaction was higher in the clonidine group. The interventional cardiologists were satisfied in both groups., Conclusion: Sufentanil and clonidine were effective as sedative in patients undergoing heart catheterization.

- Abstract
Objective: To evaluate the effects of clonidine on heart rate (HR), and blood pressure (BP) as well as its sedative effect on patients submitted to a cineangiocardiography., Methods: A randomized, controlled, double blind, prospective clinical trial was conducted on 62 patients submitted to an elective cineangiocardiography. The patients were divided in two groups: the clonidine group, that were administered a 0.8 microg/kg dose of this drug and the control group, that were administered a 0.9% saline solution. Sedation was evaluated based on the Ramsay Scale and the administration of a 0.04 mg/kg dose of meperidine that was given to the patients who were agitated or anxious during the procedure. The invasive BP, HR and sedation score based on the Ramsay Scale were analyzed every 5 minutes and four different intervals were considered for the assessment: I1- start of the test; I2- 5 minutes after the start of the test; I3- median time of the test and I4- end of the test., Results: The clonidine group presented better BP and HR stability and sedation efficacy while the control group presented a higher intake of meperidine (p<0.05). In the statistical analysis, the inference of the continuous variables was calculated using the Student's t-test or Mann-Whitney test and the chi2 or Fisher Exact Probability test was used for the categorical variables., Conclusion: This study demonstrated that clonidine was an efficient means to control BP and HR and provided a conscious sedation for patients submitted to a cineangiocardiography.
