Incidence of adverse events among elderly vs non-elderly patients during procedural sedation and analgesia with propofol.

Purpose of review The present review provides an overview of the different fields of procedural sedation and analgesia (PSA), describing the evidence from recently published studies concerning anxiety and moderate pain, cardiac interventions, gastrointestinal interventions, and PSA use in infants. It also provides guidance for practitioners of both unscheduled and scheduled procedural sedation, and a summary of the current guideline for PSA. Recent findings Safety always has to be first priority. Recently published literature is focusing on the combination of different well established drugs such as dexmedetomidine, remifentanil, propofol, and ketamine. These traditional and well known drugs are commonly used for PSA. The combinational use of multiple drugs seems to have benefits for both the provider and patient. Furthermore, there is growing interest into specific protocols and adaption for special circumstances. The preferred medications used for PSA should be both effective and well tolerated. Summary Procedural sedation deserves to have high degree of attention for potential adverse events. New combinations of well established drugs provide a better pharmacokinetic profile, fit to different indications and offer multiple benefits for both provider and patient.

Procedural sedation outside the operating room.

Procedural sedation and analgesia (PSA) is performed for a variety of indications in emergency departments (EDs). Although the practice of PSA in the ED is somewhat unique from other clinical areas, there is currently no guideline for this practice in Japan. Policy statements and guidelines for PSA have been published in Europe and North America. These guidelines suggest first evaluating patients carefully before performing PSA, and then deciding on target sedative level and choice of medications. Patient evaluation requires a combination of continuous visual observation by trained medical staff to assess the depth of sedation and respiration with noninvasive measurements of blood pressure, continuous electrocardiography monitoring, and pulse oximetry. Sedative selection should be based on its characteristics, peak time, effectiveness, and risks. It is important to administer sedatives and analgesics in small, incremental doses while keeping a close eye on the patient's reaction to avoid adverse events (AEs) until the planned sedation level is reached. Further, additional attention is needed for special populations such as pediatric and elderly patients. PSA is a key element for patient-centered care in emergency medicine. In this manuscript, we review the available evidence for PSA in the EDs, including guidelines for evaluation, monitoring, pharmacology, AEs, and special populations such as pediatric and elderly patients.

A mini‐review of procedural sedation and analgesia in the emergency department

Dexmedetomidine (DEX), a centrally acting alpha‐2 agonist, is increasingly used for sedation in multiple clinical settings. Evidence from the intensive care unit and operative settings suggests DEX may have significant advantages over traditional GABAergic sedatives such as benzodiazepines. There has been limited research on the use of DEX in the emergency department (ED).

The use of dexmedetomidine in the emergency department: A systematic review

Background Many sedative regimens have been studied with controversial efficiencies. This study tried to assess the desirable and adverse effects of sodium thiopental–fentanyl (TF) with ketamine–propofol (KP) for procedural sedation and analgesia in the emergency department. Methods After signing written consent, patients were enrolled in this randomised double-blind trial to receive either KP or TF to reach the desired sedation level. The respiratory and haemodynamic complications, nausea and vomiting, recovery agitation, patient recall and satisfaction, provider satisfaction and recovery time were compared. Results Of the participants, 47 in the KP group and 49 in the TF group were enrolled. The mean and SD scores were 6.91±1.93 and 8.34±1.25 for patients’ satisfaction and 7.55±1.54 and 8.65±1.00 for satisfaction of physicians performing the procedures in TF and KP groups, respectively (p=0.000). Moreover, 39 (79.59%) and 18 (38.29%) of patients declared that they had recalled the procedures in the TF and KP groups, respectively (p=0.000). Transient hypoxia was reported in 2.1% and 8.1% in the KP and TF groups leading to perform 4.2% vs 8.1% airway manoeuvres, respectively, without the need for endotracheal intubation or further admission. Conclusions KP and TF combinations were effectively comparable although KP resulted in higher patient and provider satisfaction. This study did not detect a difference regarding adverse respiratory or haemodynamic effects. It is estimated that the TF combination can be potent and efficacious with possible low adverse events in procedural sedation.

Comparison of the efficacy of ketamine- propofol versus sodium thiopental-fentanyl in sedation: a randomised clinical trial.

Procedural sedation and analgesia (PSA) is widely performed outside of the operating theater, often in emergency departments (EDs). The practice and safety of PSA in the ED in an aging society such as in Japan have not been well described. We aimed to characterize the practice pattern of PSA including indications, pharmacology and incidence of adverse events (AEs) in Japan. We formed the Japanese Procedural Sedation and Analgesia Registry, a multicenter prospective observation registry of ED patients undergoing PSA. We included all patients who received PSA in the ED. PSA was defined as any systemic pharmacological intervention intended to facilitate a painful or uncomfortable procedure. The main variables in this study were patients’ demographics, American Society of Anesthesiologists (ASA) physical status, indication of PSA, medication choices, and AEs. The primary outcome measure was overall AEs from PSA. We enrolled 332 patients in four EDs during the 12-month period. The median age was 67 years (IQR, 46–78). In terms of ASA physical status, 79 (23.8%), 172 (51.8%), and 81 (24.4%) patients were class 1, 2, 3 or higher, respectively. The most common indication was cardioversion (44.0%). The most common sedative used was thiopental (38.9%), followed by midazolam (34.0%) and propofol (19.6%). Among all patients, 72 (21.7%, 95% confidence interval, 17–26) patients experienced one or more AEs. The most common AE was hypoxia (9.9%), followed by apnea (7.2%) and hypotension (3.5%). All of the AEs were transient and no patient had a serious AE. In a multicenter prospective registry in Japan, PSA in the ED appears safe particularly since the patients who underwent PSA were older and had a higher risk profile compared to patients in previous studies in different countries.
