Background: Procedural sedation and analgesia (PSA) is commonly performed in emergency departments (EDs) to reduce anxiety, discomfort, or pain during a procedure. The primary goal of PSA is to produce a state of relaxation and drowsiness without eliminating the patient’s protective reflexes. Despite the discovery of new techniques and medications to deliver PSA, there is a paucity of research evaluating PSA in EDs over the last decade. We aim to describe the current practice of PSA in an Australian tertiary mixed ED with 75,000 presentations per year. Methods: A retrospective study of the initial 3 months of a PSA registry, which was part of the Tasmanian Emergency Care Outcomes Registry, was analyzed; Results: All told, 80 consecutive cases were entered over a 3-month period, with pediatric patients (<14 years old) making up 35% of all cases. Joint reductions (17, 39%) and fracture reductions (13, 29%) were the most common indications for the adult population, whilst fracture reductions (9, 36%), laceration repairs (7, 28%), and other distressing procedures (7, 28%) were the most common indications in the pediatric cohort. Pharmacological approaches also differed between groups, with ketamine (25, 92%) preferred in the pediatric cohort whilst the combination of propofol and fentanyl (22, 42%) was preferred in the adult cohort. No adverse events were recorded in the pediatric cohort whilst 6 (8%) minor events occurred in the adult population, with no severe events occurring for either cohort. PSA also occurred more frequently at 0900–1000 and the incidence was reduced between 0000 and 0800. Conclusions: PSA is commonly performed in our tertiary mixed ED and is both safe and effective, with non-severe complication rates similar to those in the reported literature. Severe complications are rare and therefore a larger cohort will be required to assess this aspect. The approach to ED PSA is also different between pediatric and adult populations and therefore research needs to differentiate both populations.
