Multicenter Study Observational Study
Development of a prediction model for postoperative pneumonia: A multicentre prospective observational study.
Postoperative pneumonia is associated with increased morbidity, mortality and costs. Prediction models of pneumonia that are currently available are based on retrospectively collected data and administrative coding systems. ⋯ We identified five variables independently associated with postoperative pneumonia. The model performed well and after external validation may be used for risk stratification and management of patients at risk of postoperative pneumonia.

Multicenter Study Comparative Study Observational Study
Monitoring haemodynamic response to fluid-challenge in ICU: comparison of pressure recording analytical method and oesophageal Doppler: A prospective observational study.
The ability of the pressure recording analytical method (PRAM) in tracking change in cardiac output (ΔCO) after a fluid challenge in ICU needs to be evaluated with the most contemporary comparison methods recommended by experts. ⋯ When compared with ODM, PRAM has insufficient performance to track ΔCO induced by fluid challenge in ICU patients. Baseline bias is an independent predictor of trending bias.

Orthostatic intolerance following hip arthroplasty: incidence, risk factors and effect on length of stay: A prospective cohort study.
Early postoperative mobilisation is important for enhanced recovery, but can be hindered by orthostatic intolerance, characterised by dizziness, nausea, vomiting, feeling of heat, blurred vision and ultimately syncope. Although the incidence of orthostatic intolerance following total hip arthroplasty has been identified, few studies have yet investigated potential risk factors for developing orthostatic intolerance after hip arthroplasty. ⋯ Orthostatic intolerance is common after total hip arthroplasty. Optimising pain control prior to mobilisation and limiting gabapentin use may modify the risk of developing postoperative orthostatic intolerance. Although personalised recovery pathways appear attractive, at present, the ability to predict at-risk individuals is still limited.

Observational Study
Peri-operative endothelial dysfunction in patients undergoing minor abdominal surgery: An observational study.
Myocardial injury after noncardiac surgery is common and associated with major adverse cardiac events. Surgery induces acute endothelial dysfunction, which might be central in the pathophysiology of myocardial injury; however, the relationship between surgical stress and endothelial function remains incompletely understood. ⋯ Elective minor abdominal surgery impaired systemic endothelial function early after surgery.

Observational Study
Noninvasive continuous arterial pressure monitoring with Clearsight during awake carotid endarterectomy: A prospective observational study.
Continuous noninvasive blood pressure (CNBP) measurement using the volume-clamp method is a less invasive alternative compared with invasive intra-arterial monitoring for awake patients during carotid endarterectomy (CEA) under regional anaesthesia. ⋯ During CEA performed under regional anaesthesia, CNBP offers a less invasive approach for BP monitoring. We found acceptable agreement for MAP defined by an ATI of 0.88 and an excellent 95% global interchangeability rate. A suboptimal bias of 7 mmHg was found with CNBP for MAP.
