Intubation without prior administration of muscle relaxants is a common practice in children and adults with potential difficult airways. We aimed to investigate the effects of adding different doses of propofol on tracheal intubation and the time to return of spontaneous breathing during inhalation induction of patients. 150 patients undergoing operations were randomly given propofol IV at 1.0, 1.5 and 2.0 mg/kg (namely 1.0-propofol, 1.5-propofol and 2.0-propofol, respectively) after inhalational induction with sevoflurane. Tracheal intubating conditions, time to return of spontaneous breathing, postoperative hoarseness, end-tidal carbon dioxide concentration (PETCO2), and pulse oxygen saturations (SpO2) were assessed. ⋯ However, PETCO2 in group 2.0-propofol was significantly higher than in groups 1.0-propofol or 1.5-propofol. Propofol at a dose of 1.5 mg/kg provides intubating conditions similar to propofol at 2.0 mg/kg in patients. Time to return of spontaneous breathing followed by a dose of 1.5 mg/kg propofol was significantly shorter than that followed by a dose of 2.0 mg/kg propofol.

Transcutaneous electric acupoint stimulation (TEAS) at Jiaji acupuncture points has therapeutic potential for relieving viscera pain and opioid-related side effects. This prospective, randomized, triple-blinded, placebo-controlled trial was to investigate the efficacy of TEAS on abdominal pain after colonoscopy. ⋯ Pretreatment with TEAS can reduce post-procedural discomfort, provide more efficient medical resources utilization, and improved patient's satisfaction and colonoscopy acceptance.

There are many risk factors for the cause of postoperative cognitive dysfunction (POCD), however, the anesthesia selection always trigger controversy for the POCD occurrence. This study aims to explore the relationship between the anesthesia and the occurrence of POCD in elder patients, and also investigate the mechanism of the POCD. One hundred elder patients with hip replacement were included in this study, which were divided into general anesthesia (GA) and epidural analgesia (EA) group. ⋯ MMSE scores of POCD patients positively correlated with Aβ or tau level (P < 0.05). In conclusion, the epidural analgesia method was better than general analgesia method for the hip replacement in elder patients. The mechanism of the POCD may be caused by the enhancement of Aβ and Tau protein.

Adjuvant sufentanil could achieve effective spinal anesthesia with low dose of hyperbaric ropivacaine for cesarean delivery. Two previous studies had calculated the 50% effective dose (ED50) of intrathecal ropivacaine coadministered with sufentanil for cesarean delivery. However, the 95% effective dose (ED95) of intrathecal hyperbaric ropivacaine coadministered with sufentanil for cesarean delivery remains uncertain. ⋯ The ED50 (95% confidence interval [CI]) for successful anesthesia was 8.4 (4.0-9.8) mg and the ED95 (95% CI) was 11.4 (9.7-13.9) mg. The results show that the ED95 of intrathecal hyperbaric ropivacaine coadministered with sufentanil 5 μg for cesarean delivery was 11.4 mg. The addition of sufentanil could significantly reduce the dosage of ropivacaine.

Anemia is an important public health and clinical problem. Observational studies have linked iron deficiency and anemia in children with many poor outcomes, including impaired cognitive development. In this study, we summarize the evidence for the effect of daily iron supplementation on cognitive performance in primary-school-aged children. ⋯ We identified 3219 studies; of these, we evaluated 5 full-text papers including 1825 children. Iron supplementation cannot improve global cognitive scores (Mean difference 1.05, 95% confidence interval [CI] -2.69 to 4.79, P<0.01). Our analysis suggests that iron supplementation improves global cognitive c outcomes among primary-school-aged children is still unclear.
