Review Meta Analysis
Meta-analysis of preoperative high-sensitivity cardiac troponin measurement in non-cardiac surgical patients at risk of cardiovascular complications.
Patients undergoing major non-cardiac surgery are at risk of cardiovascular complications. Raised levels of high-sensitivity troponin are frequently detected before operation among these patients. However, the prognostic value of high-sensitivity troponin in predicting postoperative outcomes remains unclear. ⋯ Raised preoperative levels of high-sensitivity troponin appear to represent a risk for postoperative major adverse cardiac events and mortality. Further study is required before high-sensitivity troponin can be used to predict risk stratification in routine clinical practice.

Randomized Controlled Trial Comparative Study
Randomized clinical trial of continuous transversus abdominis plane block, epidural or patient-controlled analgesia for patients undergoing laparoscopic colorectal cancer surgery.
The optimal analgesia regimen after laparoscopic colorectal cancer surgery is unclear. The aim of the study was to characterize the beneficial effects of continuous transversus abdominis plane (TAP) blocks initiated before operation on outcomes following laparoscopic colorectal cancer surgery. ⋯ Continuous TAP analgesia not only improved gastrointestinal motility but also shortened duration of hospital stay. A decreased opioid requirement and attenuating surgical stress response may be potential mechanisms. Registration number: ChiCTR-TRC-1800015535 ( http://www.chictr.org.cn).

Adequate fluid balance before, during and after surgery may reduce morbidity. This review examines current concepts surrounding fluid management in major elective surgery. ⋯ Perioperative fluid management is a key challenge during major surgery. Individualized volume optimization by means of goal-directed therapy is warranted during high-risk surgery. In most patients, balanced crystalloids are the first choice of fluids to be used in the operating theatre. Additional research on the optimal type of fluid for use during major surgery is needed.

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.

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.
