  • Effects of one-lung ventilation time on bronchoalveolar lavage fluid and serum inflammatory markers after radical operation of esophageal cancer: A prospective cohort study

    Objective To investigate the effects of one-lung ventilation time on the concentration of tumor necrosis factor (TNF)-α and interleukin (IL)-6 in the bronchoalveolar lavage fluid (BALF), serum inflammatory markers and early pulmonary infection after radical resection of esophageal cancer. Methods Ninety patients with thoracoscope and laparoscopic radical resection of esophageal carcinoma were chosen. According to the thoracoscope operation time, the patients were divided into 3 groups including a T1 (0.5–1.5 hours) group, a T2 (1.5–2.5 hours) group and a T3 (>2.5 hours) group. Immediately after the operation, the ventilated and collapsed BALF were taken. Enzyme-linked immunosorbent assay (ELISA) method was used to determine the concentration of IL-6 and tumour necrosis TNF-α. The concentrations of procalcitonin (PCT), C-reactive protein (CRP), and white blood cell (WBC) were measured on the first, third, fifth day after operation. The incidence of pulmonary infection was observed within 3 days after operation. Result The IL-6 values of the right collapsed lung in all groups were higher than those in the left ventilated lung. The TNF-α value of the right collapsed lung in the T2 group and T3 group was higher than that in the left ventilated lung (P<0.05). Compared with in the right collapsed lung, the TNF-α and IL-6 values gradually increased with the the duration of one-lung ventilation (P<0.05). Compared with the left ventilated lung groups, the IL-6 value increased gradually with the duration of one-lung ventilation time (P<0.05). The TNF-α value of the T3 group was higher than that of the T1 and T2 groups (P<0.05). The PCT value of the T3 group was higher than that of the T1 group and T2 group on the third, fifth day after operation (P<0.05). But there was no significant difference in CRP and WBC among the three groups at different time points. The incidence of pulmonary infection in the T3 group was significantly higher than that in the T1 group within 3 days after operation (P<0.05). Conclusion With the extension of one-lung ventilation time, the release of local and systemic inflammatory mediators is increased, and the probability of pulmonary infection is higher.

  • Effect of dexmedetomidine on prognosis of patients after cardiac surgery with cardiopulmonary bypass: A systematic review and meta-analysis

    Objective To evaluate the clinical efficacy of dexmedetomidine in perioperative management of on-pump cardiac surgery. Methods Randomized controlled trials (RCTs) were identified through a systematic literature search of PubMed, EBSCO, Web of Science, Cochrane Library, CBM, CNKI, Wanfang Database (up to December 2016). RevMan 5.3 software was used for meta-analysis. Results Sixteen studies with 1 432 patients were included. Dexmedetomidine significantly decreased the risk of postoperative delirium (RR=0.28, 95% CI 0.18 to 0.44, P<0.000 01) and postoperative atrial fibrillation (RR=0.65, 95% CI 0.44 to 0.98, P=0.04) compared with the controls. The duration of intubation (RR=–1.96, 95% CI –2.07 to –1.86, P<0.000 01), length of ICU stay (RR=–0.49, 95% CI –0.74, –0.24, P=0.000 1) and hospital stay (RR=–1.24, 95% CI –2.26 to –0.22, P=0.02) in the dexmedetomidine group were significantly shorter than those of the control group. In addition, dexmedetomidine was shown to improve the score of the the Montreal Cognitive Assessment (RR=0.88, 95% CI 0.42 to 1.35, P=0.000 2) compared to the control group. Conclusion Dexmedetomidine can reduce the complications after cardiac surgery, which is safe and effective. However, more studies with good methodologic quality and large samples are still needed to make further assessment.
