ABSTRACT
Background:Pulmonary artery hypertension (PAH) dreadful complication in bronchiectasis. The 6thworld symposium on pulmonary hypertension have taken mPAPof 20 mmHg as normal. Not much studies have been done based on the current cut off values, so we have incorporated values based on the new guidelines and made following observations. Methods: Thisstudy was designed as an observational cross-sectional study consisting of 27 patients, who were admitted in Pulmonary medicine department. Results:Out of 27 study subjects 15 were female抯 and 12 were males. It was found that 70.3% had less than 5 segments involved and 29.6% had more than 5 segments involved. Mean value of PAH was 34.48�.06 mmHg. Analysis showed a significant correlation (r=0.67) between number of segments involved and incidence of pulmonary hypertension. Conclusions: Itis essential to evaluate the cardiac status of bronchiectasis patients at the time of diagnosis as cardiac manifestations are one of the dreadful complications.
ABSTRACT
ABSTRACT: The present study aimed to evaluate the effects of different sedation protocols on blood pressure and echocardiographic and electrocardiographic parameters in dogs. In total, 24 male mixed-breed dogs with a mean weight of 9.87±3.0kg were used.Animals were randomly divided into four groups (n=6), which were subjected to sedation using the following protocols: acepromazine (0.05mgkg-1) and butorphanol (0.3mgkg-1) (AB); acepromazine (0.05mgkg-1)and methadone (0.5mgkg-1) (AM); acepromazine (0.03mgkg-1), methadone (0.5mgkg-1), and midazolam (0.3mgkg-1)(MAM); and methadone only (0.5mgkg-1) (M). Indirect blood pressure (BP) measurements and computerized electrocardiography (ECG) and echocardiography (ECO) were performed immediately before the application of the sedation protocol (baseline), and the same evaluations were repeated after 15 minutes. BP decreased in groups AB, MAM, and AM compared to baseline values. Electrocardiographic measurements showed decreased heart rates (HRs) after sedation in all groups, and bradycardia was observed after sedation in two dogs from group M and one animal from group AM. The P-wave duration increased after sedation in groups AM and M. After sedation, no changes in cardiac dimensions were revealed byECO.Fractional shortening (FS) decreased after sedation in the AM group, and dogs from group AB exhibited a smaller decrease in FS compared with the other groups. The cardiac index (CI) was lower in groups AM and M than in the other groups. Animals from group AB were less resistant to examination and exhibited the most favorable sedation scores. It was concluded that the combination of acepromazine and butorphanol was the best sedation protocol for performing echocardiogram measurementsbecause dogs were less resistant to examinations and echocardiographic parameters of FS and CI remained stable.
RESUMO: O objetivo deste estudo foi avaliar os efeitos de diferentes protocolos de sedação sobre a pressão arterial, parâmetros ecocardiográficos e eletrocardiográficos em cães. Foram utilizados 24 cães, machos, SRD, com peso médio de 9,87±3,0kg, os quais foram alocados aleatoriamente em quatro grupos (n=6), que foram submetidos à sedação com os protocolos acepromazina (0,05mgkg-1) e butorfanol (0,3mgkg-1) (AB), acepromazina (0,05mgkg-1) e metadona (0,5mgkg-1) (AM), acepromazina (0,03mgkg-1), metadona (0,5mgkg-1) e midazolam (0,3mgkg-1) (MAM) e metadona isolada (0,5mgkg-1) (M). Foi realizada avaliação da pressão arterial sistólica (PAS) não invasiva, eletrocardiografia computadorizada e ecocardiografia imediatamente antes da aplicação do protocolo de sedação (basal) e repetindo-se as mesmas avaliações, 15 minutos após. Observou-se redução na PAS nos grupos AB, MAM, AM, em relação ao basal. Na eletrocardiografia, houve redução da FC após sedação em todos grupos, sendo observada bradicardia após sedação em dois cães do grupo M e um animal do grupo AM. A duração da onda P aumentou após sedação nos grupos AM e M. Não foram observadas alterações nas dimensões cardíacas, avaliadas pela ecocardiografia, após sedação. A fração de encurtamento (FS) reduziu após sedação no AM e os cães do AB apresentaram menor queda da FS, diferindo dos demais grupos. O índice cardíaco (IC) foi menor no AM e M em relação aos demais. Os animais do grupo AB foram menos resistentes à execução dos exames, apresentando melhores escores de sedação. Concluiu-se que a associação acepromazina e butorfanol foi o melhor protocolo de sedação para realização do ecocardiograma, sendo os cães menos resistentes à execução do exame, mantendo estáveis os parâmetros ecocardiográficos de fração de encurtamento e índice cardíaco.
ABSTRACT
The Philippine Council for Health Research and Development-Department of Science and Technology (PCHRD-DOST), and the Philippine College of Surgeons (PCS) signed a Memorandum of Agreement on 1 June 1999, whereby both agreed to support the formation of Evidence-Based Clinical Practice Guidelines (EBCPGs) on specific areas of surgical care in the Philippines. The areas were to be specified by the PCS, and those areas should have a reasonably large potential of improving the quality of patient care throughout the country, and can be implemented nationwide in both government and private health facilities The first clinical area selected was on when to refer for preoperative cardiac evaluation for elective noncardiac surgery, and when would the intraoperative presence of a cardiologist be beneficial. A Technical Working Group (TWG) was appointed, which: 1) searched and appraised the evidence; 2) prepared a first draft EBCPG; 3) presented the evidence to a Panel of Experts; 4) supervised the panel using the nominal group technique (6 November 1999 - PCS Building); and 5) prepared the second draft EBCPG based on the consensus recommendations of the panel. All processes strictly conformed to the methods of evidence-based guidelines formation specified by evidence-baesd medicine texts The second draft EBCPG was presented on 11 December 1999 during the 55th Clinical Congress of the PCS, and the final draft approved by the PCS Board of Regents on 29 January 2000 Literature search was conducted through the MEDLINE, COCHRANE Library an the HERDIN Database. A total of 2,156 titles, 427 abstracts and 77 full text articles were appraised. Data from 23 prospective cohort studies were encoded into the software COCHRANE Review Manager (RevMan), Version 3.0 for Windows (updated October 7, 1996). Tables were generated which contained authors, outcome rates, relative risks and the 95% confidence intervals of the relative risks. Three perioperative outcomes were identified-cardiac morbidity, cardiac death, and overall cardiac events
