The correlation among the Ramsay sedation scale, Richmond agitation sedation scale and Riker sedation agitation scale during midazolam-remifentanil sedation / Correlação entre a escala de sedação de Ramsay, escala de sedação-agitação de Richmond e escala de sedação-agitação de Riker durante sedação com midazolam-remifentanil

Abstract Background and objectives: Sedative and analgesic treatment administered to critically ill patients need to be regularly assessed to ensure that previously stated goals are well achieved as the risk of complications of oversedation is minimized. We revised and prospectively tested the Ramsay Sedation scale (RSS) for interrater reliability and compared it with the Sedation-Agitation Scale (SAS) and the Richmond Agitation Sedation Scale (RASS) to test construct validity during midazolam-remifentanil sedation. Methods: A convenience sample of ICU patients was simultaneously and independently examined by pairs of trained evaluators by using the revised SAS, RSS, and RASS. Ninety-two ICU patients were examined a total of 276 times by evaluator pairs. Results: The mean patient age was 61.32 ± 18.68 years, 45,7% were female (n = 42), 54.3% male (n = 50). Their APACHE values varied between 3 and 39 with an average of 13.27 ± 7.86 and 75% of the cases were under mechanical ventilation. When classified by using RSS (2.70 ± 1.28), 10.9% were anxious or agitated (RSS1), 68.5% were calm (RSS 2-3), and 20.6% were sedated (RSS 4-6). When classified by using RASS (-0.64 ± 1.58), 20.7% were anxious or agitated (RASS+1 to +4), 63.0% were calm (RASS 0 to -2), and 16.3% were sedated (RASS -3 to -5). When classified by using SAS (2.63 ± 1.00), 12% were anxious or agitated (SAS 5-7), 57.6% were calm (SAS 4), and 30.4% were sedated (SAS 1-3). RSS was correlated with the SAS (r = -0.656, p < 0.001) and RASS was correlated with the SAS (r = 0.565, p < 0.001). RSS was highly correlated with the RASS (r = -0.664, p < 0.001). Conclusions: Ramsay is both reliable and valid (high correlation with the RASS and SAS scales) in assessing agitation and sedation in adult ICU patients.

Resumo Justificativa e objetivos: O tratamento de pacientes em estado crítico com sedativos e analgésicos deve ser regularmente avaliado para garantir que as metas pré-definidas sejam atingidas, bem como minimizar o risco de complicações resultantes de sedação em excesso. Conduzimos uma revisão e testamos prospectivamente a Escala de Sedação de Ramsay (Ramsay Sedation Scale [RSS]) para a confiabilidade interavaliador e a comparamos com a Escala de Sedação e Agitação de Riker (Riker Sedation-Agitation Scale [RRSAS]) e a Escala de Sedação e Agitação de Richmond (Richmond Agitation Sedation Scale [RASS]) para testar a validade de construto durante a sedação com midazolam-remifentanil. Métodos: Uma amostra de conveniência de pacientes de UTI foi simultânea e independentemente examinada por pares de avaliadores treinados com o uso das escalas revisadas RRSAS, RSS e RASS. Foram examinados 92 pacientes de UTI por pares de avaliadores em 276 momentos. Resultados: A média dos pacientes foi de 61,32 ± 18,68 anos; 45,7% eram do sexo feminino (n = 42) e 54,3% do masculino (n = 50). Seus escores APACHE variaram entre 3-39, com média de 13,27 ± 7,86, e 75% dos casos receberam ventilação mecânica. Quando RSS foi usada para a classificação (2,70 ± 1,28), 10,9% dos pacientes estavam ansiosos ou agitados (RSS1), 68,5% estavam calmos (RSS 2 a 3) e 20,6% estavam sedados (RSS 4 a 6). Quando RASS foi usada para a classificação (-0,64 ± 1,58), 20,7% dos pacientes estavam ansiosos ou agitados (RASS +1 a +4), 63,0% estavam calmos (RASS 0 a -2) e 16,3% estavam sedados (RASS -3 a -5). Quando RSAS foi usada para a classificação (2,63 ± 1,00), 12% dos pacientes estavam ansiosos ou agitados (RSAS 5 a 7), 57,6% estavam calmos (RSAS 4) e 30,4% estavam sedados (RSAS 1 a 3). Houve correlação de RSS com RSAS (r = -0,656, p < 0,001) e de RASS com RSAS (r = 0,565, p < 0,001). Houve forte correlação de RSS com RASS (r = -0,664, p < 0,001). Conclusões: A RSS é confiável e válida (forte correlação com RASS e RSAS) para avaliar a sedação e agitação em pacientes adultos internados em UTI.

Antipsychotic-induced tardive movement disorders: a series of twelve cases.

BACKGROUND: Prolonged use of antipsychotic drugs (AP) with or without sudden withdrawal as well as high dosage of AP (at least 3 months) may result in a variety of movement disorders such as classical tardive dyskinesia (tongue rolling, lip pouting, trunkal choreiform movements), tardive myoclonus (sudden, brief involuntary jerking), tardive dystonia (tongue protrusion, torticollis, scoliosis, jaw spasm, bruxism, abnormal trunkal posture, or "Pisa syndrome", strong contraction of arm and leg). Patients with severe symptoms often suffer from body pain and fractures of bones due to frequent fallings. They are also accused of "faking" to call attention or they believe that the symptoms are signs of being "cursed or posses in". OBJECTIVE: To report twelve patients of antipsychotic drug induced tardive movement disorders including tardive dystonia, tardive myoclonus, and tardive Parkinsonism. Patients were incorrectly diagnosed as epilepsy, conversion (pseudo seizure), or hypochondriasis. RESULTS: In the present series, there were eight men and four women with age ranging from 13 to 72 years. All patients had been taking both typical and atypical antipsychotic drugs for at least one year. Strong involuntary movement disorders, torticollis, scoliosis, body pain, difficulty in swallowing, and aphonia were observed Most patients were thin and anemic. They responded well to diazepam, anticholinergic drug, clonazepam lithium, and antidepressant while antipsychotic drugs were discontinued in most cases. Calcium salt and iron supplement appeared to be useful. CONCLUSION: Physicians should be aware of these abnormal movement disorders induced by AP drugs to detect early and provide prompt treatment. AP drug should be used cautiously to prevent this iatrogenic effect particularly in high- risk patients.

Akathisia--diagnostic dilemma and behavioral treatment.

Akathisia, an involuntary movement disorder resulting from exposure to antipsychotics, is characterized by subjective restlessness and a strong desire to move about. The diagnosis is often complicated by the overlapping symptoms of pseudoakathisia, chronic akathisia and tardive dyskinesia. This report deals with a patient with schizophrenia who developed akathisia after exposure to antipsychotics. Later, she developed movements that were more like pseudoakathisia and tardive dyskinesia rather than acute akathisia. On failure of anti-akathisia medication, she was treated with a behavioral regime to which her akathisia responded. This behavioral regime used the technique of distraction as a primary tool. This case report highlights the diagnostic difficulties in akathisia and the application of behavioral treatment for akathisia that is non-responsive to anti-akathisia medication.
