Observational Study
Risk factors of acute urinary retention after spine surgery.
Acute postoperative urinary retention (APOUR) is 1 of the most common complications of spinal surgery, impacting both postoperative care and the patients' quality of life. This study is designed to investigate the risk factors and the incidence of APOUR after spinal surgery in Taiwan. We conducted a retrospective analysis using the Taiwanese National Health Insurance Research Database (NHIRD), a nationwide cohort of patients who underwent spinal surgery from the year 2000 to 2013. ⋯ Multivariate logistic regression analysis revealed that age (adjusted odds ratio [OR] = 1.02, 95% CI = 1.01-1.02), male gender (adjusted OR = 1.35, 95% CI = 1.10-1.60) and undergoing spinal surgery more than 2 times (adjusted OR = 4.78, 95% CI = 2.49-9.20) were statistically significant risk factors for APOUR after spinal surgery. The results of this retrospective cohort study suggest that patients undergoing spinal surgery more than 2 times, male gender and advanced age are significantly associated with an increased risk of APOUR after spinal surgery. This information may assist surgeons to identify patients who have a high risk of APOUR after spinal surgery and proactively provide them with early intervention.

Randomized Controlled Trial
Association between thoracic epidural anesthesia and driving pressure in adult patients undergoing elective major upper abdominal surgery: a randomized controlled trial.
Thoracic epidural anesthesia (TEA) is associated with a knowledge gap regarding its mechanisms in lung protection and reduction of postoperative pulmonary complications (PPCs). Driving pressure (ΔP), an alternative indicator of alveolar strain, is closely linked to reduced PPCs with lower ΔP values. We aim to investigate whether TEA contributes to lung protection by lowering ΔP during mechanical ventilation. ⋯ Compared to GA, TEA-GA can reduce intraoperative ΔP in patients undergoing major upper abdominal surgery, especially those undergoing laparoscopic surgery. However, compared to GA combined with ΔP-guided ventilation, TEA-GA combined with ΔP-guided ventilation does not reduce the risk of PPCs. There was no significant difference in the total use of various vasoactive drugs between the two groups.

Acute kidney injury develops frequently after nephrectomy, causing increased hospital duration of stay and mortality. Both propofol and volatile anaesthetic agents are thought to have renoprotective effects. We investigated whether the type of maintenance anaesthetic (propofol or desflurane) affected the incidence of acute kidney injury after nephrectomy. ⋯ The type of anaesthetic maintenance drug (propofol vs. desflurane) did not affect the incidence of acute kidney injury after nephrectomy. Future research might be better directed towards investigating other potentially modifiable risk factors for postoperative acute kidney injury in this patient population.

Review Meta AnalysisInotropes for the prevention of low cardiac output syndrome and mortality for paediatric patients undergoing surgery for congenital heart disease: a network meta-analysis.
Paediatric patients undergoing surgery for congenital heart disease (CHD) are at risk for postoperative low cardiac output syndrome (LCOS) and mortality. LCOS affects up to 25% of children after heart surgery. It consists of reduced myocardial function and increases postoperative morbidity, prolongs mechanical ventilation, and lengthens the duration of intensive care unit (ICU) stay. Pharmacological prophylaxis involves inotropes, including catecholamines, phosphodiesterase III inhibitors, or calcium sensitisers, to enhance myocardial contractility. It is unclear whether they are effective in preventing LCOS or death in this vulnerable population. ⋯ Levosimendan likely results in a large reduction in mortality compared to placebo in paediatric patients undergoing surgery for congenital heart disease, whereas milrinone likely results in no difference, and the effect of dobutamine is unknown. Low cardiac output syndrome (LCOS) is largely reduced with levosimendan, likely largely reduced with milrinone, and may be reduced with low-dose milrinone, compared to placebo. The length of ICU stay may be no different with levosimendan and is likely no different with milrinone or with dobutamine, compared to placebo. The length of hospital stay is likely no different with levosimendan or with milrinone, but is likely reduced with dobutamine, compared to placebo. The duration of mechanical ventilation is likely increased with levosimendan or with milrinone and is likely no different with dobutamine, compared to placebo. Adverse events are likely increased with levosimendan or dobutamine, and may be increased with milrinone and decreased with low-dose milrinone, compared to placebo. The evidence is based on few, heterogeneous studies, with small numbers of patients and short follow-up periods. Future research should include large numbers of patients, consistently report all co-interventions, and ensure the longest possible follow-up.

Delirium is one of the most common neurological complications after cardiac surgery. The purpose of our study was to assess the relationship between perioperative blood pressure variability (BPV) and postoperative delirium (POD) in the patients undergoing cardiac surgery. ⋯ Perioperative ARV, especially postoperative high ARV exposure, was associated with POD in the patients receiving cardiac surgery. Maintaining a relatively stable blood pressure after cardiac surgery might be beneficial to avoid POD in those patients.
