BackgroundLocal anesthetic infiltration has been used to manage postoperative pain in various surgeries. The present study was aimed to investigate the effect of skin infiltration with 0.5 % ropivacaine on postoperative pain in patients undergoing craniotomy.MethodsOne hundred and six patients with ASA I/II scheduled to undergo elective craniotomy were enrolled during March to November in 2015 in this prospective, randomized, placebo-controlled, double-blind study. After the anesthesia induction, skin along the incision was infiltrated with 0.5 % ropicavaine (group R, n = 53) or 0.9 % normal saline (group C, n = 53), respectively. Morphine was used as rescue analgesic postoperatively. Morphine consumption during the first 24 postoperative hours was recorded as the primary outcome, and the time to first rescue requirement was also recorded. Pain was assessed at 2, 4, 8, 24 h, 7 days, 3 months after surgery by visual analog scale (VAS). Heart rate and mean arterial pressure were recorded before anesthesia induction (T1), after anesthesia induction (T2), after scalp infiltration (T3), during skull drilling (T4), mater cutting (T5) and skin closure (T6).ResultsMorphine consumption during the first 24 postoperative hours was significantly higher in group C than in group R (13.36 [6.5, 20] vs. 6.3 [0, 10] mg, P < 0.05). The first time of patients needed rescue analgesic was prolonged in group R as compared with group C (6.16 [3.4, 8.0] vs. 3.87 [2.3, 4] h, P < 0.05). Postoperative VAS and hemodynamic signs during the first 24 h showed no significant difference in two groups. The incidence of persistent pain on 7 days and 3 months postoperatively had no significant differences between two groups. Besides one patient (2 %) enduring moderate pain (VAS 4–7) in group C, the number of patients suffering from mild pain (VAS 1–3) was 17 (33.3 %) in group R and 17 (34 %) in group C 3 months after surgery.ConclusionThe results suggest 0.5 % ropivacaine scalp infiltration before skin incision has favorable analgesic effect in reducing morphine consumption and prolong the time of first rescue analgesic requirement after surgery.Trial registration Chinese Clinical Trial Registry (http://www.chictr.org.cn/) registration number: ChiCTR-IPR-14005717
Background: Our aim was to determine the relationship between the use of fluoroquinolones and the risk of aortic diseases. Methods: PubMed, EMBASE and the Web of Science were searched from inception to July 6, 2019, to identify observational studies that evaluated the risk of aortic diseases associated in users of fluoroquinolones compared with nonusers or users of other antibiotics. The primary outcome was the first occurrence of aortic diseases. We used the GRADE approach to rate the strength of evidence. We used the inverse variance method random-effect model to estimate the odds ratios (ORs) with 95% CIs, and statistical heterogeneity was assessed by the I 2 statistic. Results: This meta-analysis enrolled 2,829,385 patients reported the relationship between fluoroquinolones and the risk of aortic diseases. Compared with nonusers or users of other antibiotics, users of fluoroquinolone had a significantly increased risk of aortic diseases (adjusted OR, 2.10; 95% CI, 1.65-2.68; P = .000, I 2 = 16.4%). The quality of evidence was moderate, and the number needed to harm (NNH) for aortic diseases among patients was estimated to be 1301. Conclusions: The fluoroquinolone use in patients significantly increases the risk of new-onset aortic diseases. Clinicians need to pay attention to these severe adverse events when considering fluoroquinolone use.
Summary Background The perioperative period can be psychologically challenging, and children may exhibit behavioral changes following surgical anesthesia. It is unknown whether children in China have additional risk factors associated with negative behavioral changes. Objectives The aim of this study was to investigate the incidence of behavioral changes in children after hypospadias repair surgery and to identify potential risk factors associated with negative behavioral changes. Methods A prospective cohort of 177 children aged 2‐12 years scheduled for hypospadias repair surgery from 2016 to 2017 was studied. The primary outcome was the incidence of behavioral changes on postoperative days 14 and 30 evaluated with the Post‐Hospitalization Behavioral Questionnaire. Data collected included demographic data, anesthesia details, procedure details, admission details, child anxiety, child temperament, pain, and emergence delirium. Multivariable logistic regression was used to identify risk factors associated with postoperative negative behavioral changes. Results A total of 60.5% (107/177) of children exhibited negative postoperative behavioral changes on day 14 and 46.5% (79/170) exhibited changes on day 30 after the surgery. Approximately 2.3% (4/177) and 2.4% (4/170) of children showed improved behavior on postoperative days 14 and 30, respectively. The frequency of temper tantrums changed the most. The logistic regression results suggested that a younger age (odds ratio: 0.86; 95% confidence interval 0.76‐0.96), emotional temperament (odds ratio: 1.1; 95% confidence interval 1.0‐1.2) and maternal education (odds ratio: 2.2; 95% confidence interval 1.1‐4.5) were associated with negative postoperative behavioral changes on day 14. On day 30, a younger age (odds ratio: 0.87; 95% confidence interval 0.77 to 0.98) was the only factor associated with negative postoperative behavioral changes. Conclusion For children undergoing hypospadias repair surgery in our institution, approximately three in five showed postoperative behavioral changes. In addition to a younger age and a higher maternal education, an emotional temperament is associated with a high incidence of negative postoperative behavioral changes.
Up-regulating the expression of occludin and down-regulating the expressions of TLR4 and NF-kappaB, and hence inhibiting TNF-alpha expression and improving the mucosa barrier function may be part of the mechanisms of BWXLS in treating oxazolone-induced colitis in mice.
