“…Examples of precipitating factors are electrolyte disturbances, anemia, postoperative infections, and volume overload during surgery. 16,17 As primary caregivers, nurses play an important part in recognizing and identifying postoperative delirium. 18,19 However, nurses often misread the clinical signs of delirium, especially hypoactive delirium.…”

“…In addition to mortality, postoperative cognitive impairments such as POD and postoperative cognitive dysfunction (POCD) impose a huge burden on individuals and society [9]. The incidence of POD is dependent on perioperative and intraoperative risk factors [10]. Therefore, the incidence of POD varies within a broad range [11,12].…”

Postoperative delirium (POD) is a common and serious adverse event in the elderly patient and is associated with significant morbidity and mortality. A new treatment for POD by intravenous Intralipid injection in the recovery room is first suggested in the medical literature.Keywords: Postoperative delirium; Postoperative cognitive dysfunction; Intralipid Post Operative DeliriumDelirium is defined by either the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) [1] or by the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD 10, Table 3) [2]. Delirium is an acute and fluctuating alteration of mental state of reduced awareness and disturbance of attention. POD (Post Operative Delirium) often starts in the recovery room and occurs up to 5 days after surgery [3][4][5]. One investigation [4] found that many patients with POD on the peripheral ward already had POD in the recovery room.More than 230 million surgical procedures are performed each year worldwide, of which more than 80 million are in Europe [6][7][8]. In Europe, the in-hospital mortality rate up to a maximum of 60 days is 3% after elective surgery and nearly 10% after emergency surgery [7]. In addition to mortality, postoperative cognitive impairments such as POD and postoperative cognitive dysfunction (POCD) impose a huge burden on individuals and society [9]. The incidence of POD is dependent on perioperative and intraoperative risk factors [10]. Therefore, the incidence of POD varies within a broad range [11,12]. For example, a metaanalysis of 26 studies of POD reported an incidence of 4.0 to 53.3% in hip fracture patients and 3.6 to 28.3% in elective patients [13].Delirium is one of the most common complications following hip fracture surgery in older people. This study identified pre-and peri-operative factors associated with the development of postoperative delirium following hip fracture surgery.Published and unpublished literature were searched to identify all evidence reporting variables on patient characteristics, onadmission, intra-operative and post-operative management assessing incident delirium in older people following hip fracture surgery. Pooled odds ratio (OR) and mean difference of those who experienced delirium compared to those who did not were calculated for each variable. Evidence was assessed using the Downs and Black appraisal tool and interpreted using the GRADE approach.A total of 6704 people (2090 people with postoperative delirium) from 32 studies were analyzed. There was moderate evidence of nearly a two-times greater probability of post-operative-delirium for those aged 80 years and over (OR: 1.77; 95% CI: 1.09, 2.87), whether patients lived in a care institution pre-admission (OR: 2.65; 95% CI: 1.79, 3.92), and a six-times greater probability of developing post-operative delirium with a pre-admission diagnosis of dementia (OR: 6.07, 95% CI: 4.84, 7.62). There was no association with intra-operative variables and probability of deliri...
