ACCM and SCCM have joined with ASHP to develop new clinical practice guidelines in 2002 The recommendations were graded according to the strength and quality of the scientific evidence. “pain, agitation, and delirium” (PAD) guidelines N Engl J Med 2014; 370:444-454 Recommendation The quality of evidence High (level A), moderate (level B), or low/very low (level C), based on both study design The strength of recommendations was defined Strong (1) Weak (2), Either for (+) or against (–) an intervention A no recommendation (0) A strong recommendation either in favor of (+1) or against (–1) ICU 病房的止痛與鎮靜 目的: 不痛 使病人在半睡半醒中,保持安靜與放鬆狀態. 止痛劑(analgesia) Morphine 是最好的選擇。 Meperidine (no more than 48 hrs or dose>600mg/24hrs): metabolize to normeperidine. Contraindication 1. renal impairment 2. MAOI. Duration of the morphine and meperidine : 3-4 hrs. CHOICE OF SEDATIVE AGENT No sedative drug is clearly superior to all others. Midazolam, lorazepam , propofol, dexmedetomidine. Remifentanil, an opioid, is also used as a sole agent because of its sedative effects. Benzodiazepines : γ-aminobutyric acid type A (GABAA) receptors, as in part does propofol An α2-adrenoceptor agonist : dexmedetomidine μ-opioid receptor agonist : remifentanil is a Sedatives and Analgesics in Common Use in the ICU.). The choice of agent by tradition and familiarity CHOICE OF SEDATIVE AGENT For rapidly adjusted : propofol or remifentanil Propofol vs BZD : reduction in the length of stay in the ICU. Dexmedetomidine has advantages over benzodiazepines analgesia, less respiratory depression, more interactive to communicate their needs. Less delirium and a shorter duration of mechanical ventilation not reduced stays in the ICU or hospital. Remifentanil : T1/2 3 to 4 minutes that is independent of the infusion duration or organ function. Surgical patients in ICU Small trials Not a common choice in most ICUs. 2017/5/25 評估工具 (sedation) Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the Intensive 2017/5/25 Care UnitCrit Care Med 2013; 41:263–306 ICU 病房的鎮靜藥物使用 Propofol 用於BZA (lorazepam)無法成功鎮靜的病人。as a last resort for patients not successfully sedated with high dose lorazepam (>20mg/h or >240mg/day, morphine, and haloperidol. 限住加護病房使用人工呼吸器治療且需要每日進行 神智評估之病例使用。 每日劑量10-25amps,每次使用以不超過72小時為 原則。 不得作為例如性使用。 Propofol Propofol 主要用於鎮靜安眠,但也有抗癲癇與輕微失 憶作用。 高脂溶性,開始作用速度快 (< 1 minute)與停藥快速恢 復。經肝臟 conjugation 成為不活性代謝物, 再經腎臟 排除。 肝腎功能不全並不影響藥物排除。 抗嘔吐作用 : short duration of action. 副作用 : 低血壓 ( especially a bolus dose) 重要問題 propofol is prepared in a solution of soybean oil, glycerol, and purified egg phosphatide.( sepsis and death) 呼吸與心臟.

The pathophysiology of delirium Uncharacterized and may vary depending on the cause. Increased risk : GABAA agonists and anticholinergic drugs Central cholinergic deficiency Excess dopaminergic activity Pharmacologic management : empirical. A clinical diagnosis (incidence in the ICU 16% to 89%) Risk factors Advanced age, more than one condition associated with coma, followed by treatment with sedative medications, a neurologic diagnosis, and increased severity of illness. Increased mortality 10% increase in the relative risk of death for each day of delirium, and decreased long-term cognitive function. Two distinct forms of delirium Hypoactive and agitated (or hyperactive).mixed delirium. Hypoactive form inattention, disordered thinking, and a decreased level of consciousness without agitation. Pure agitated delirium < 2% in the ICU. least likely to survive, better long-term function than those with agitated or mixed delirium.

In septic shock, on mechanical ventilation with a lowtidal-volume protocol with positive end-expiratory pressure (PEEP) Norepinephrine infusion Analgesia : continuous morphine infusion Question What sedation should be provided to this patient? Answer Major surgery : a laparotomy, Pain assessment and control Sedation to ensure ventilator synchrony and to prevent self-harm through the accidental removal of vascular access lines or the endotracheal tube. Benzodiazepines : most commonly Short-acting anesthetic agent : propofol α2-adrenoceptor agonist : dexmedetomidine, popular Previous heavy alcohol intake and mild cognitive impairment At high risk for delirium Riker Sedation–Agitation Scale (SAS) or the Richmond Agitation–Sedation Scale (RASS) Daily interruption of sedation Short-acting, minimum dose : be beneficial The avoidance of benzodiazepines : reduce the risk of delirium.
