Protective Effect of Targeted Fluid Therapy on Patients with One-Lung Ventilation.

Objective: To evaluate the protective effect of target-directed fluid therapy on the lungs and postoperative rehabilitation in elderly patients with single-lung ventilation undergoing total endoscopic radical resection of esophageal cancer. Methods: Seventy elderly patients who underwent total endoscopic radical resection of esophageal cancer from January 2017 to December 2019 in our hospital were selected and divided into two groups by the random number table method: the goal-directed fluid treatment group (group G, n = 35) and the control group (group C, n = 35). Venous blood was extracted before surgery (T1), at the end of free esophagus (T2) by thoracoscopy, at the end of abdominal surgery (T3), and at the end of surgery (T4). IL-6 and IL-10 levels were detected by ELISA. The clinical pulmonary infection score (CIPS) was used to evaluate the pulmonary inflammation on the second day after surgery and the occurrence of complications. Duration of antibiotic use and length of hospital stay were recorded. Results: At T1, there were no significant differences in IL-6 and IL-10 levels between the two groups (P > 0.05). At T2, the IL-6 level in group G increased to 26.65 ± 1.80 pg/ml but was significantly lower than that in group C (32.28 ± 3.22 pg/ml) (P < 0.01). At T3 and T4, IL-6 and IL-10 levels in group G were significantly lower than those in group C (P < 0.01). The CIPS score of group G was lower than that of group C (1.5 ± 1.0 vs 2.7 ± 1.4), and the duration of antibiotic use in group G was shorter than that in group C (211.2 ± 15.4 vs 232.6 ± 18.7 h), with statistical significance (P < 0.01). The incidence of complications in group G was lower than that in group C (28.6% vs 40.0%), and the length of hospital stay in group G was shorter than that in group C (10.5 ± 1.7 vs 11.2 ± 1.9 days), but there was no significant difference between the two groups (P > 0.05). Conclusion: Target-directed fluid therapy inhibited inflammatory cytokine levels and had better lung protection, but no significant benefit in the complications or the length of hospital stay was observed.

Intravenous lidocaine infusion for pain control after laparoscopic cholecystectomy: A meta-analysis of randomized controlled trials.

BACKGROUND: This meta-analysis aimed to assess the efficiency and safety of intravenous infusion of lidocaine for pain management after laparoscopic cholecystectomy (LC). METHODS: A systematic search was performed in PubMed (August 1966-2017), Medline (August 1966-2017), Embase (August 1980-2017), ScienceDirect (August 1985-2017), and the Cochrane Library. Only randomized controlled trials (RCTs) were included. Fixed/random effect model was used according to the heterogeneity tested by I2 statistic. Meta-analysis was performed using Stata.11.0 software. RESULTS: A total of 5 RCTs were retrieved involving 274 patients. The present meta-analysis indicated that there were significant differences between groups in terms of visual analog scale scores at 12hours (weighted mean difference [WMD]=-0.743, 95% CI: -1.246 to -0.240, P = .004), 24hours (WMD=-0.712, 95% CI: -1.239 to -0.184, P = .008), and 48hours (WMD=-0.600, 95% CI: -0.972 to -0.229, P = .002) after LC. Significant differences were found regarding opioid consumption at 12hours (WMD=-3.136, 95% CI: -5.591 to -0.680, P = .012), 24hours (WMD=-4.739, 95% CI: -8.291 to -1.188, P = .009), and 48hours (WMD=-3.408, 95% CI: -5.489 to -1.326, P = .001) after LC. CONCLUSION: Intravenous lidocaine infusion significantly reduced postoperative pain scores and opioid consumption after LC. In addition, there were fewer adverse effects in the lidocaine groups. Higher quality RCTs are still required for further research.
