Sedation Scale (sedation + scale)
Selected AbstractsPremedication with melatonin vs midazolam in anxious childrenPEDIATRIC ANESTHESIA, Issue 7 2008BERRIN ISIK MD Summary Aim:, Failure of dental treatment caused by anxiety is a common problem in children. Oral midazolam has been the most commonly used premedication for pediatric patient but the use of midazolam may be associated with paradoxical reactions in children. Melatonin may induce a natural sleepiness and improve sedation. We have investigated premedication with melatonin compared with midazolam in children under nitrous oxide/oxygen (N2O/O2) sedation for dental treatment. Methods:, In a randomized study, 60 children received either 3 mg of melatonin [Melatonina (3 mg®) 60 min before the procedure (n = 15); group I], 0.5 mg·kg,1 melatonin 60 min before the procedure (n = 15; group II), 0.75 mg·kg,1 midazolam [Dormicum (15 mg/3 ml ®) 15 min before the procedure (n = 15); group III] or 3 ml of 0.09 NaCl 15 min (n = 7) or 60 min before the procedure (n = 8; group IV) orally. The children were sedated with 40/60% N2O/O2 inhalation. The heart rate and O2 saturation were monitored during the treatment period. The level of sedation was assessed according to the Ramsay Sedation Scale. The children's sedation success during dental treatment was classified. The sedation success and other sedation-related events recorded. Comparisons among the four groups were made using one-way anova or Kruskal,Wallis test, and if any significant differences were noted, the Tukey's HSD or Mann,Whitney U -test were used for intergroup comparisons. All differences were considered significant at P < 0.05. Results:, The evaluation of sedation success was as follows: group I: satisfactory (n = 1), average satisfactory (n = 4), and unsatisfactory (n = 10); group II: satisfactory (n = 2), average satisfactory (n = 3), and unsatisfactory (n = 10); group III: satisfactory (n = 9), average satisfactory (n = 6); and group IV: satisfactory (n = 1), average satisfactory (n = 3), and unsatisfactory (n = 11). Conclusion:, In these doses and clinical conditions, melatonin was similar to that of placebo and did not contribute to N2O/O2 sedation of anxious children. [source] Delirium in Older Emergency Department Patients: Recognition, Risk Factors, and Psychomotor SubtypesACADEMIC EMERGENCY MEDICINE, Issue 3 2009Jin H. Han MD Abstract Objectives:, Missing delirium in the emergency department (ED) has been described as a medical error, yet this diagnosis is frequently unrecognized by emergency physicians (EPs). Identifying a subset of patients at high risk for delirium may improve delirium screening compliance by EPs. The authors sought to determine how often delirium is missed in the ED and how often these missed cases are detected by admitting hospital physicians at the time of admission, to identify delirium risk factors in older ED patients, and to characterize delirium by psychomotor subtypes in the ED setting. Methods:, This cross-sectional study was a convenience sample of patients conducted at a tertiary care, academic ED. English-speaking patients who were 65 years and older and present in the ED for less than 12 hours at the time of enrollment were included. Patients were excluded if they refused consent, were previously enrolled, had severe dementia, were unarousable to verbal stimuli for all delirium assessments, or had incomplete data. Delirium status was determined by using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) administered by trained research assistants (RAs). Recognition of delirium by emergency and hospital physicians was determined from the medical record, blinded to CAM-ICU status. Multivariable logistic regression was used to identify independent delirium risk factors. The Richmond Agitation and Sedation Scale was used to classify delirium by its psychomotor subtypes. Results:, Inclusion and exclusion criteria were met in 303 patients, and 25 (8.3%) presented to the ED with delirium. The vast majority (92.0%, 95% confidence interval [CI] = 74.0% to 99.0%) of delirious patients had the hypoactive psychomotor subtype. Of the 25 patients with delirium, 19 (76.0%, 95% CI = 54.9% to 90.6%) were not recognized to be delirious by the EP. Of the 16 admitted delirious patients who were undiagnosed by the EPs, 15 (93.8%, 95% CI = 69.8% to 99.8%) remained unrecognized by the hospital physician at the time of admission. Dementia, a Katz Activities of Daily Living (ADL) , 4, and hearing impairment were independently associated with presenting with delirium in the ED. Based on the multivariable model, a delirium risk score was constructed. Dementia, Katz ADL , 4, and hearing impairment were weighed equally. Patients with higher risk scores were more likely to be CAM-ICU positive (area under the receiver operating characteristic [ROC] curve = 0.82). If older ED patients with one or more delirium risk factors were screened for delirium, 165 (54.5%, 95% CI = 48.7% to 60.2%) would have required a delirium assessment at the expense of missing 1 patient with delirium, while screening 141 patients without delirium. Conclusions:, Delirium was a common occurrence in the ED, and the vast majority of delirium in the ED was of the hypoactive subtype. EPs missed delirium in 76% of the cases. Delirium that was missed in the ED was nearly always missed by hospital physicians at the time of admission. Using a delirium risk score has the potential to improve delirium screening efficiency in the ED setting. [source] Effect of epidural dexmedetomidine on intraoperative awareness and post-operative pain after one-lung ventilationACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010M. ELHAKIM Background: During combined general and regional anaesthesia, it is difficult to use autonomic signs to assess whether wakefulness is suppressed adequately. We compared the effects of a dexmedetomidine,bupivacaine mixture with plain bupivacaine for thoracic epidural anaesthesia on intraoperative awareness and analgesic benefits, when combined with superficial isoflurane anaesthesia (<0.05 maximum alveolar concentration) in patients undergoing thoracic surgery with one-lung ventilation (OLV). Methods: Fifty adult male patients were randomly assigned to receive either epidural dexmedetomidine 1 ,g/kg with bupivacaine 0.5% (group D) or bupivacaine 0.5% alone (group B) after induction of general anaesthesia. Gasometric, haemodynamic and bispectral index values were recorded. Post-operative verbal rating score for pain and observer's assessment of alertness/sedation scale were determined by a blinded observer. Results: Dexmedetomidine reduced the use of supplementary fentanyl during surgery. Patients in group B consumed more analgesics and had higher pain scores after operation than patients of group D. The level of sedation was similar between the two groups in the ICU. Two patients (8%) in group B reported possible intraoperative awareness. There was a limited decrease in PaO2 at OLV in group D compared with group B (P<0.05). Conclusion: In thoracic surgery with OLV, the use of epidural dexmedetomidine decreases the anaesthetic requirements significantly, prevents awareness during anaesthesia and improves intraoperative oxygenation and post-operative analgesia. [source] The Richmond Agitation-Sedation Scale: translation and reliability testing in a Swedish intensive care unitACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2010M. ALMGREN Background: Awareness about adequate sedation in mechanically ventilated patients has increased in recent years. The use of a sedation scale to continually evaluate the patient's response to sedation may promote earlier extubation and may subsequently have a positive effect on the length of stay in the intensive care unit (ICU). The Richmond Agitation-Sedation Scale (RASS) provides 10 well-defined levels divided into two different segments, including criteria for levels of sedation and agitation. Previous studies of the RASS have shown it to have strong reliability and validity. The aim of this study was to translate the RASS into Swedish and to test the inter-rater reliability of the scale in a Swedish ICU. Methods: A translation of the RASS from English into Swedish was carried out, including back-translation, critical review and pilot testing. The inter-rater reliability testing was conducted in a general ICU at a university hospital in the south of Sweden, including 15 patients mechanically ventilated and sedated. Forty in-pair assessments using the Swedish version of the RASS were performed and the inter-rater reliability was tested using weighted , statistics (linear weighting). Result: The translation of the RASS was successful and the Swedish version was found to be satisfactory and applicable in the ICU. When tested for inter-rater reliability, the weighed , value was 0.86. Conclusion: This study indicates that the Swedish version of the RASS is applicable with good inter-rater reliability, suggesting that the RASS can be useful for sedation assessment of patients mechanically ventilated in Swedish general ICUs. [source] Comparison of the effect of protocol-directed sedation with propofol vs. midazolam by nurses in intensive care: efficacy, haemodynamic stability and patient satisfactionJOURNAL OF CLINICAL NURSING, Issue 11 2008Liou Huey-Ling MSN Aim., The aim of this study was to compare the effect of protocol-directed sedation propofol vs. midazolam by nurses in intensive care on efficacy, haemodynamic stability and patient satisfaction. Background., Protocols represent one method potentially to reduce treatment delays and ensure that medical care is administered in a standardised manner. Propofol and midazolam are often used for sedation in intensive care units. Method., A randomised, prospective cohort study and data were collected in 2003. The subjects were randomised either into propofol (n = 32) or into midazolam (n = 28) group. Efficacy of sedation, haemodynamic stability, pulse oximetry saturation, Acute Physiology and Chronic Health Evaluation II (APACHE II score), weaning time from mechanical ventilation, duration of mechanical ventilation, length of stay at intensive care unit, sedative drugs cost and patient satisfaction were measured. Results., The nursing staff were able to maintain patients at Ramsay sedation scale (RSS) 3,4 during the sedative period. The efficacy of sedation was 74·2% and 66·9% of time in propofol and midazolam group respectively. Both sedatives reduced the arterial blood pressure and heart rate, but did not alter haemodynamic stability. The mean score of satisfactory sedation was not significantly different between the two groups (propofol: 11·4 SEM 0·2 vs. midazolam: 11·5 SEM 0·7). Conclusion., Protocol-directed sedation with propofol vs. midazolam by nurses were similar in quality during the sedative period. Relevance to clinical practice., This sedation practice for titration of propofol and midazolam by nurses was of similar quality and able to achieve an appropriate depth of sedation during the sedative period. Furthermore, they should provide care for patients' needs during the sedative period. [source] | ||||||||||
