Randomized Controlled Trial
Randomized clinical trial of intraoperative dexmedetomidine to prevent delirium in the elderly undergoing major non-cardiac surgery.
Delirium is common in elderly patients after surgery and is associated with poor outcomes. This study aimed to investigate the impact of intraoperative dexmedetomidine on the incidence of delirium in elderly patients undergoing major surgery. ⋯ Intraoperative dexmedetomidine halved the risk of delirium in the elderly after major non-cardiac surgery. Registration number: ChiCTR-IPR-15007654 ( www.chictr.org.cn).

Obesity has become an increasing problem worldwide during the past few decades. Hence, surgeons and anaesthetists will care for an increasing number of obese patients in the foreseeable future, and should be prepared to provide optimal management for these individuals. This review provides an update of recent evidence regarding perioperative strategies for obese patients. ⋯ Obese patients require comprehensive preoperative evaluation. Experienced medical teams, appropriate equipment and monitoring, careful anaesthetic management, and an adequate perioperative ventilation strategy may improve postoperative outcomes. Additional perioperative precautions are necessary in patients with severe morbid obesity, metabolic syndrome, untreated or severe obstructive sleep apnoea syndrome, or obesity hypoventilation syndrome; patients receiving home ventilatory support or postoperative opioid therapy; and obese patients undergoing open operations, long procedures or revisional surgery.

Multicenter Study Observational Study
Safety and efficacy of non-steroidal anti-inflammatory drugs to reduce ileus after colorectal surgery.
Ileus is common after elective colorectal surgery, and is associated with increased adverse events and prolonged hospital stay. The aim was to assess the role of non-steroidal anti-inflammatory drugs (NSAIDs) for reducing ileus after surgery. ⋯ NSAIDs did not reduce the time for gastrointestinal recovery after colorectal surgery, but they were safe and associated with reduced postoperative opioid requirement.

Review Meta Analysis
Network meta-analysis of local and regional analgesia following colorectal resection.
Postoperative pain management after colorectal surgery remains challenging. Systemic opiates delivered on demand or via a patient-controlled pump have traditionally been the mainstay of treatment. Opiate analgesia is associated with slower gastrointestinal recovery and unpleasant side-effects; many regional and local analgesic techniques have been developed as alternatives. ⋯ Spinal analgesia and transversus abdominus plane blocks best balanced pain control and opiate minimization in the immediate postoperative phase following colorectal resection. Multimodal analgesia reduces pain, minimizes systemic opiate use and optimizes postoperative recovery.

Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis. ⋯ Women in the UK had a disproportionate risk of admission without surgical intervention and had high rates of normal appendicectomy. Risk prediction models to support shared decision-making by identifying adults in the UK at low risk of appendicitis were identified.
