RESUMO
OBJECTIVE: When cognitive impairment precludes patients' report of symptoms, it becomes necessary to use other means. The purpose of our study was to evaluate the validity of the method currently in use on our service. METHOD: Two members of the team simultaneously assessed the patient and independently recorded whether the patient showed signs of discomfort, and a third questioned patients with cognitive failure who maintained some ability to respond if something was bothering them. RESULTS: Some 200 assessments were made of 116 patients. The kappa coefficient of agreement was 0.615. The sensitivity was 17% and specificity 99%. The positive predictive value was 88%, and the negative predictive value was 73%. SIGNIFICANCE OF RESULTS: Due to the low sensitivity of this method, it cannot be recommended as a screening tool.

In the literature regarding delirium and agitation in palliative care, there are references of their worsening as the hours of the day flows from afternoon on, with an inversion of the awake-sleep cycle. We studied the frequency of the use of our protocol for the control of agitation. From June 18, 2007, to January 4, 2010, 27 (5.3%) patients from the 509 admitted were sedated intermittently 86 times, in strict compliance with the protocol, because of episodes of agitation. We verified that from 8 pm until 6 am, the number of observed cases clearly exceeds the expected cases, if the distribution was uniform. The reverse situation occurs in all other hours of the day. The chi-square goodness of fit test proves that the differences are statistically significant (P < .001).

Agitation is one of the most frequent causes for palliative sedation. It often requires urgent control to avoid negative consequences and even endangerment of all involved, including the patients themselves. A protocol for the control of episodes of agitation was developed, based on a previous experience. The protocol includes a combination of haloperidol and midazolam. The protocol was used 86 times in 27 patients. Each patient was sedated from 1 to 12 times, median 2 times. The median time from the beginning of sedation to the control of agitation was 15 minutes with a range from 1 minute (2 cases) to 3 hours and 5 minutes (only 1 case). In 71 cases (83%), only the first dose was needed. There were no significant complications.
