Sedative and analgesic treatment administered to critically ill patients need to be regularly assessed to ensure that predefinite goals are well achieved as the risk of complications of oversedation is minimized. In most of the cases, which are lightly sedation patients, the goal to reach is a calm, cooperative and painless patient, adapted to the ventilator. Recently, eight new bedside scoring systems to monitor sedation have been developed and mainly tested for reliability and validity. The choice of a sedation scale measuring level of consciousness, could be made between the Ramsay sedation scale, the Richmond Agitation Sedation scale (RASS) and the Adaptation to The Intensive Care Environment scale-ATICE. The Behavioral Pain Scale (BPS) is a behavioral pain scale. Two of them have been tested with strong evidence of their clinimetric properties: ATICE, RASS. The nurses'preference for a convenient tool could be defined by the level of reliability, the level of clarity, the variety of sedation and agitation states represented user friendliness and speed. In fine, the choice between a simple scale easy to use and a well-defined and complex scale has to be discussed and determined in each unit. Actually, randomized controlled studies are needed to assess the potential superiority of one scale compared with others scales, including evaluation of the reliability and the compliance to the scale. The usefulness of the BIS in ICU for patients lightly sedated is limited, mainly because of EMG artefact, when subjective scales are more appropriated in this situation. On the other hand, subjective scales are insensitive to detect oversedation in patients requiring deep sedation. The contribution of the BIS in deeply sedation patients, patients under neuromuscular blockade or barbiturates has to be proved. Pharmacoeconomics studies are lacking.

Sedation-analgesia occupies an essential place in the specific therapeutic arsenal of the brain-injured patients. The maintenance of the perfusion of the brain, its relaxation and its protection are the fundamental objectives whose finality is to avoid the extension of the lesions and to preserve the neuronal capital. Sedation is instituted when patients are severely agitated or present a deterioration of their state of consciousness (GCS< or =8). Under cover of mechanical ventilation, sedation is the first line treatment of intracranial hypertension, a common pathway of various acute brain diseases of traumatic, vascular or other origin. The use of the combination of hypnotic and opioids is the rule. The combined action of these two classes reinforces and improves their sedative effects. Midazolam is the 2 benzodiazepine of reference. Propofol is more and more frequently added to the combination of hypnotic and opioids. The "propofol infusion syndrome" is a severe limitation to its long term administration in particular among patients presenting a severe septic or inflammatory state. Propofol will be imperatively stopped in the event of metabolic acidosis, rhabdomyolysis, acute renal insufficiency, hyperkaliemia or increase in the blood triglyceride levels. The use of thiopental is restricted to the most severe cases. Its use as a monotherapy at high doses is abandoned to the profit of a co-administration with midazolam or even with the combination of midazolam and propofol. Thiopental overdose is very frequent in the event of associated hypothermia. Etomidate does not have its place apart from induction in fast sequence. The neuro-protective effects of ketamine require to be demonstrated in man before being recommended routinely. Withdrawal of sedation can be responsible for a state of agitation which can be controlled by neuroleptics.

In intensive care units, patients are sedated to reduce the stress caused by illness and/or treatments such as artificial respiration. Regular assessment of the degree of sedation as part of the goal-directed therapy has been recommended as a standard of care. The Swiss Society of Intensive Care Medicine requires all accredited Swiss intensive care units to periodically document the degree of sedation by means of a sedation scale as part of the minimal data set (MDSi). The ten-level Richmond Agitation-Sedation Scale (RASS) is one of two proposed scales for the assessment of the degree of sedation. Because validated versions of the recommended sedation scales exist in English only, the RASS was translated by a systematic iterative procedure in six steps. The iterative translation of the RASS for use in Swiss intensive care units described in this article is an example of interdisciplinary teamwork. Translation of clinical assessment tools for clinical use should be carried out as carefully and stringently as the development of research tools. Based on the experience gained in the described project we recommend the following points to consider when translating clinical assessment tools: a) referring to literature not only on the subject of translation but also on the process of translation itself, b) involving professional translators as language experts, and c) consulting the author(s) of the original version.

Administering sedative and analgesic medications is a cornerstone of optimizing patient comfort and minimizing distress, yet may lead to unintended consequences including delayed recovery from critical illness and slower liberation from mechanical ventilation. The use of structured approaches to sedation management, including guidelines, protocols, and algorithms can promote evidence-based care, reduce variation in clinical practice, and systematically reduce the likelihood of excessive and/or prolonged sedation. Patient-focused sedation algorithms are multidisciplinary, including physician, nurse, and pharmacist development and implementation. Key components of sedation algorithms include identification of goals and specific targets, use of valid and reliable tools to assess analgesia, agitation, and sedation, and incorporation of logical medication selection. Sedation protocols generally focus on a) algorithms that incorporate treating sedation and analgesia based upon escalation, de-escalation, or changing medications according to specific targets, or b) daily interruption of sedative and opioid analgesic infusions. Many published sedation protocols have been tested in controlled clinical trials, often demonstrating benefit such as shorter duration of mechanical ventilation, reduced ICU length of stay, and/or superior sedation management compared to usual care. Implementation of sedation algorithms in ICUs is a challenging process for which sufficient resources must be allocated.

A descriptive survey-based study was undertaken to test the validity and reliability of three scales that are used to assess sedation during opioid administration for pain management: the Inova Health System Sedation Scale (ISS), the Richmond Agitation and Sedation Scale (RASS), and the Pasero Opioid-Induced Sedation Scale (POSS). The study was conducted in a large (830 beds) suburban level I trauma hospital with a random convenience sample of 96 medical-surgical nurses. The study reports: measures of reliability and validity of each scale and significant findings related to correct nursing score and selected actions; nurses' ratings of each scale in terms of combined ease of use; information provided by the scale to inform clinical decisions; and nursing confidence measures. Both the RASS and the POSS demonstrated adequate measures of reliability and validity for measurement of sedation during opioid administration for pain management. However, the POSS scored higher in combined measures of ease of use, nursing confidence, and usefulness of information provided to make clinical decisions. The POSS also yielded the highest percentage agreement with the correct score and correct nursing actions chosen by the nurse among the three scales tested. Study results have clinical significance for accuracy of clinical assessments and subsequent actions on behalf of patients experiencing advancing sedation during opioid analgesia. The POSS can be recommended as a superior sedation scale for the measurement of sedation during opioid administration for pain management.

Optimizing sustained use of ICU sedation in mechanically ventilated patients requires careful consideration of drug-specific characteristics (E.G. pharmacokinetics), consideration of potential adverse effects in susceptible patients, and utilization of sedation-minimizing strategies. In the era of anxiolytic dosing protocols adjusted to specific patient behaviors as defined by sedation scales in conjunction with daily interruption, midazolam is a reasonable option for long-term sedation. Propofol is an appealing agent for ICU sedation due to it's pharmacokinetic profile and a reduced propensity to result in prolonged sedation. However, care should be taken to monitor for potential devastating adverse effects including hypertriglyceridemia and propofol-related infusion syndrome (PRIS). Dexmedetomidine unreliably provides adequate sedation at doses currently approved by the FDA, though upward titration of dexmedetomidine coupled with rescue benzodiazepines and/or fentanyl appears to be safe and comparable to benzodiazepines in the achievement of light to moderate Richmond Agitation Sedation Scale (RASS) goals. Clinicians should closely monitor patients receiving dexmedetomidine for hemodynamic-altering bradycardia. Strategies that promote frequent patient assessment with corresponding sedative dose minimization have demonstrated the benefits of limiting oversedation. Implementation of a sedation protocol requires careful consideration of ICU resources and staffing such that efforts made are sustainable and will be safe and effective for the patient population affected.

Delirium is a common complication following cardiac surgery, and the predictors of delirium remain unclear. The authors performed a prospective observational analysis to develop a predictive model for postoperative delirium using demographic and procedural parameters. A total of 112 adult postoperative cardiac surgical patients were evaluated twice daily for delirium using the Richmond Agitation-Sedation Scale (RASS) and Confusion Assessment Model for the ICU (CAM-ICU). The incidence of delirium was 34% (n = 38). Increased age (odds ratio [OR] = 2.5; 95% confidence interval [CI] = 1.6-3.9; P < .0001, per 10 years) and increased duration of surgery (OR = 1.3; 95% CI = 1.1-1.5; P = .0002, per 30 minutes) were independently associated with postoperative delirium. Gender, BMI, diabetes mellitus, preoperative ejection fraction, surgery type, length of cardiopulmonary bypass, intraoperative blood component administration, Acute Physiology and Chronic Health Evaluation II score, Sequential Organ Failure Assessment score, and Charlson Comorbidity Index, were not independently associated with postoperative delirium.

Sedation has become an important part of critical care practice in minimizing patient discomfort and agitation during mechanical ventilation. Pain, anxiety, and delirium form a triad of factors that can lead to agitation. Achieving and maintaining an optimal level of comfort and safety in the intensive care unit plays an essential part in caring for critically ill patients. Sedatives, opioids, and neuromuscular blocking agents are commonly used in the intensive care unit. The goal of therapy should be directed toward a specific indication, not simply to provide restraint. Standard rating scales and unit-based guidelines facilitate the proper use of sedation and neuromuscular blocking agents. The goal of sedation is a calm, comfortable patient who can easily be aroused and who can tolerate mechanical ventilation and procedures required for their care.

Sedation and analgesia are important components of care for the mechanically ventilated patient in the intensive care unit (ICU). An understanding of commonly used medications is essential to formulate a sedation plan for individual patients. The specific physiological changes that a critically ill patient undergoes can have direct effects on the pharmacology of drugs, potentially leading to interpatient differences in response. Objective assessments of pain, sedation, and agitation have been validated for use in the ICU for assessment and titration of medications. An evidence-based strategy for administering these drugs can lead to improvements in short- and long-term outcomes for patients. In this article, we review advances in the field of ICU sedation to provide an up-to-date perspective on management of the mechanically ventilated ICU patient.

Optimal sedation and analgesia are of key importance in intensive care. The aim of this study was to assess the quality of sedoanalgesia and outcome parameters in regimens containing midazolam and either fentanyl or remifentanil. A prospective, randomized, open-label, controlled trial was carried out in the ICU unit of a large teaching hospital in Istanbul over a 9-month period. Thirty-four patients were randomly allocated to receive either a remifentanil-midazolam regimen (R group, n = 17) or a fentanyl-midazolam regimen (F group, n = 17). A strong correlation between Riker Sedation-Agitation Scale (SAS) and Ramsey Scale (RS) measurements was observed. Comparatively, remifentanil provided significantly more potent and rapid analgesia based on Behavioral-Physiological Scale (BPS) measurements and a statistically nonsignificantly shorter time to discharge. On the other hand, remifentanil also caused a significantly sharper fall in heart rate within the first six hours of treatment.
