Effect of ultrasound-guided lumbar plexus block on emergence agitation in children undergoing hip surgery: study protocol for a randomized controlled trial.

ABSTRACT: BACKGROUND:Emergence agitation (EA) is a common postoperative issue in children that causes self-injury, increases stress on healthcare team members, and even leads to postoperative maladaptive behavioral changes in children. Clear answers regarding a 'gold standard' for prevention of EA are not available. Pain is regarded as an important causative factor of EA, and ultrasound-guided lumbar plexus block is a safe and efficient anesthetic method that can provide satisfactory pain relief in pediatric hip surgery. The purpose of our study is to determine whether ultrasound-guided lumbar plexus block can reduce the incidence of EA in children undergoing hip surgery. METHODS/DESIGN:We designed a prospective, randomized, controlled, blinded trial to determine the effect of ultrasound-guided lumbar plexus block on EA. A total of 100 American Society of Anesthesiologists class I-II children (1-6?years old) scheduled for elective hip surgery will be recruited for this study. Participants will be randomized at a 1:1 ratio to receive either ultrasound-guided lumbar plexus block or fentanyl after the induction of general anesthesia. The primary outcome is the incidence of EA 30?min after emergence from anesthesia using the Pediatric Anesthesia Emergence Delirium (PAED) score. The secondary outcomes are the severity and duration of EA 30?min after emergence from anesthesia using the PAED score, postoperative pain evaluated by the Children's Hospital of Eastern Ontario Pain Scale, and the incidence of postoperative adverse events. Randomization will be conducted using a computer-generated randomization schedule. Outcome assessors and data collectors will be blinded to the group allocations. Assessments will be performed before surgery, intraoperatively, and postoperatively at every time point. DISCUSSION:Our hypothesis in this trial is that ultrasound-guided lumbar plexus block can decrease the incidence of EA in children undergoing elective hip surgery. This trial will provide clinical answers to verify our hypothesis. If our hypothesis is confirmed, the results could provide a safe method to prevent EA.

Project description:BackgroundTo relieve prostate biopsy-related pain, various local anesthetic methods have been used. The best approach was periprostatic nerve block (PNB) in the past decade. Recently, pelvic plexus block (PPB) was employed to ultrasound-guided prostate biopsy. Compared with the PNB, the PPB may block a more extensive area. Therefore, PPB may be more effective in relieving prostate biopsy-related pain. However, several prospective randomized controlled trials (RCTs) comparing PPB and PNB drew conflicting conclusions, so we compared the difference of pain control between PPB and PNB for prostate biopsy.MethodsThe following databases were retrieved up to October 2020: PubMed, Chinese biomedicine literature database, the Cochrane Library, China National Knowledge Internet databases, Wan fang databases and Google Scholar. Only the RCTs were included. The main outcome measures were Visual Analog Scale (VAS) score and complications. The literature quality and extracted data were evaluated by two authors independently. The software Review Manager (version 5.3) was used to perform the data analysis that comparing the difference of VAS score and complications between PPB and PNB.ResultsAfter screening, six articles including 336 patients from PPB group and 337 patients from PNB group were performed meta-analysis in this study. The results showed that there were no significant difference of pain control in probe insertion and local anesthetic injection between PPB and PNB, while compared with PNB, patients with PPB experienced less pain during biopsy and 30 min after biopsy, respectively(MD = -0.57, 95% CI: -1.11 to -0.03, Z = 2.06, P = 0.04; MD = -0.21, 95% CI: -0.40 to -0.02, Z = 2.15, P = 0.03). In subgroup analysis, the pooled results showed that PPB was superior to PNB in 12-cores biopsy (pooled MD = -1.16, 95% CI: -1.61 to -0.71, P < 0.00001), and more than 40-ml prostate size, regardless of transrectal or transperineal prostate biopsy. The reported major complications were urinary retention, hematuria, infection and hemospermia. The pooled results showed that there were no obvious difference in complications between PPB group and PNB group.ConclusionsOverall, this meta-analysis suggests that PPB provides safe and effective pain control of ultrasound-guided prostate biopsy, and PPB is superior to PNB. In future, it also needs more high quality, large samples RCTs to verify.

Project description:BackgroundPrevious studies of factors associated with prolonged duration of ultrasound-guided brachial plexus block have included multiple surgical procedures or multiple anesthetic approaches, all of which are important confounders, and there is no study based on a single method of anesthesia exploring the factors affecting the resolution of brachial plexus block during upper limb surgery, especially in Asians. This study aimed to identify the risk factors affecting the prolonged duration of US-guided brachial plexus block in American Society of Anesthesiologists (ASA) I-II grade patients to improve postoperative analgesia.MethodsThis study enrolled patients scheduled to undergo surgery for upper limb fracture in Anting Hospital, Shanghai from May 2021 to September 2021. Inclusion criteria: (I) patients aged 18 years and above; (II) ASA I-II grade patients; (III) success of US-guided brachial plexus block. Based on the median duration of brachial plexus block, patients were divided into a <5-hour group and a ≥5-hour group. The factors were selected base on previous studies conclution and clinical demographic characteristics of patients. Multivariable logistic regression was used to estimate relevant influencing factors.ResultsA total of 129 patients (51.2% males; 51.01±16.54 years old) were analyzed. The duration of brachial plexus block was 2-12 hours, with a median duration of 5.09 hours. Multivariable analysis suggested that age 40-49 years [odds ratio (OR): 4.841; 95% confidence interval (CI): 1.033 to 22.695; P=0.045], 50-59 years (OR: 4.730, 95% CI: 1.149 to 19.474; P=0.031), 60 years (OR: 8.540; 95% CI: 1.605 to 45.449; P=0.012), gender (OR: 3.314; 95% CI: 1.330 to 8.257; P=0.010), alanine aminotransferase (ALT; OR: 5.817, 95% CI: 1.509 to 22.472; P=0.011), and glomerular filtration rate (GFR) <60 (OR: 22.700; 95% CI: 1.994 to 198.386; P=0.012) were the risk factors for the duration of brachial plexus block.ConclusionsIt is advisable to use the lowest effective dose for the shortest possible time when using ropivacaine in upper limb fracture surgery patients with elevated ALT (≥40 U/L) and lower GFR (<60 mL/min) in male patients aged ≥60 years.
