Review
INTRODUCTION
Sickle cell disease causes chronic haemolytic anaemia, dactylitis, and painful acute crises. It also increases the risk of stroke, organ damage, bacterial infections, and complications of blood transfusion. In sub-Saharan Africa, up to a third of adults are carriers of the defective sickle cell gene, and 1% to 2% of babies are born with the disease.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: what are the effects of pharmaceutical and non-pharmaceutical interventions to prevent sickle cell crisis and other acute complications in people with sickle cell disease? What are the effects of pharmaceutical and non-pharmaceutical interventions to treat pain in people with sickle cell crisis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 38 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, antibiotic prophylaxis in children <5 years of age, antibiotic prophylaxis in childrenĀ >5 years of age, aspirin, avoidance of cold environment, blood transfusion, codeine, corticosteroid (with narcotic analgesics), diflunisal, hydration, hydroxyurea, ibuprofen, ketorolac, limiting physical exercise, malaria chemoprophylaxis, morphine (controlled-release oral after initial intravenous bolus, repeated intravenous doses), oxygen, paracetamol, patient-controlled analgesia, pneumococcal vaccines, and rehydration.

Meta-Analysis
BACKGROUND
Epidural analgesia in labour prolongs the second stage and increases instrumental delivery. It has been suggested that a more upright maternal position during all or part of the second stage may counteract these adverse effects. This is an update of a Cochrane Review published in 2017.
OBJECTIVES
To assess the effects of different birthing positions (upright or recumbent) during the second stage of labour, on maternal and fetal outcomes for women with epidural analgesia.
SEARCH METHODS
We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (5 June 2018), and the reference lists of retrieved studies.
SELECTION CRITERIA
All randomised or quasi-randomised trials including pregnant women (primigravidae or multigravidae) in the second stage of induced or spontaneous labour receiving epidural analgesia of any kind. Cluster-randomised controlled trials would have been eligible for inclusion but we found none. Studies published in abstract form only were also eligible.We assumed the experimental intervention to be maternal use of any upright position during the second stage of labour, compared with the control condition of remaining in any recumbent position.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for inclusion, assessed risks of bias, and extracted data. We contacted study authors to obtain missing data. We assessed the quality of the evidence using the GRADE approach.We carried out a planned sensitivity analysis of the three studies with low risks of bias for allocation concealment and incomplete outcome data reporting, and further excluded one study with a co-intervention (this was not prespecified).
MAIN RESULTS
We include eight randomised controlled trials, involving 4464 women, comparing upright positions versus recumbent positions in this update. Five were conducted in the UK, one in France and two in Spain.The largest UK trial accounted for three-quarters of all review participants, and we judged it to have low risk of bias. We assessed two other trials as being at low risk of selection and attrition bias. We rated four studies at unclear or high risk of bias for both selection and attrition bias and one study as high risk of bias due to a co-intervention. The trials varied in their comparators, with five studies comparing different positions (upright and recumbent), two comparing ambulation with (recumbent) non-ambulation, and one study comparing postural changes guided by a physiotherapist to a recumbent position.Overall, there may be little or no difference between upright and recumbent positions for our combined primary outcome of operative birth (caesarean or instrumental vaginal): average risk ratio (RR) 0.86, 95% confidence interval (CI) 0.70 to 1.07; 8 trials, 4316 women; I = 78%; low-quality evidence. It is uncertain whether the upright position has any impact on caesarean section (RR 0.94, 95% CI 0.61 to 1.46; 8 trials, 4316 women; I = 47%; very low-quality evidence), instrumental vaginal birth (RR 0.90, 95% CI 0.72 to 1.12; 8 trials, 4316 women; I = 69%) and the duration of the second stage of labour (mean difference (MD) 6.00 minutes, 95% CI -37.46 to 49.46; 3 trials, 456 women; I = 96%), because we rated the quality of the evidence as very low for these outcomes. Maternal position in the second stage of labour probably makes little or no difference to postpartum haemorrhage (PPH), (PPH requiring blood transfusion): RR 1.20, 95% CI 0.83 to 1.72; 1 trial, 3093 women; moderate-quality evidence. Maternal satisfaction with the overall childbirth experience was slightly lower in the upright group: RR 0.95, 95% CI 0.92 to 0.99; 1 trial, 2373 women. Fewer babies were born with low cord pH in the upright group: RR 0.43, 95% CI 0.20 to 0.90; 2 trials, 3159 infants; moderate-quality evidence.The results were less clear for other maternal or fetal outcomes, including trauma to the birth canal requiring suturing (average RR 1.00, 95% CI 0.89 to 1.13; 3 trials, 3266 women; I = 46%; low-quality evidence), abnormal fetal heart patterns requiring intervention (RR 1.69, 95% CI 0.32 to 8.84; 1 trial, 107 women; very low-quality evidence), or admission to neonatal intensive care unit (RR 0.54, 95% CI 0.02 to 12.73; 1 trial, 66 infants; very low-quality evidence). However, the CIs around some of these estimates were wide, and we cannot rule out clinically important effects.In our sensitivity analysis of studies at low risk of bias, upright positions increase the chance of women having an operative birth: RR 1.11, 95% CI 1.03 to 1.20; 3 trials, 3609 women; high-quality evidence. In absolute terms, this equates to 63 more operative births per 1000 women (from 17 more to 115 more). This increase appears to be due to the increase in caesarean section in the upright group (RR 1.29; 95% CI 1.05 to 1.57; 3 trials, 3609 women; high-quality evidence), which equates to 25 more caesarean sections per 1000 women (from 4 more to 49 more). In the sensitivity analysis there was no clear impact on instrumental vaginal births: RR 1.08, 95% CI 0.91 to 1.30; 3 trials, 3609 women; low-quality evidence.
AUTHORS' CONCLUSIONS
There may be little or no difference in operative birth between women who adopt recumbent or supine positions during the second stage of labour with an epidural analgesia. However, the studies are heterogeneous, probably related to differing study designs and interventions, differing adherence to the allocated intervention and possible selection and attrition bias. Sensitivity analysis of studies at low risk of bias indicated that recumbent positions may reduce the need for operative birth and caesarean section, without increasing instrumental delivery. Mothers may be more satisfied with their experience of childbirth by adopting a recumbent position. The studies in this review looked at left or right lateral and semi-recumbent positions. Recumbent positions such as flat on the back or lithotomy are not generally used due to the possibility of aorto-caval compression, although we acknowledge that these recumbent positions were not the focus of trials included in this review.

Meta-Analysis
BACKGROUND AND OBJECTIVES
This study is a meta-analysis of randomized controlled trials comparing the efficacy of transcutaneous electrical nerve stimulation (TENS) to a control and to other nerve stimulation therapies (NSTs) for the treatment of chronic back pain.
METHODS
Citations were identified in MEDLINE, the Cochrane Library, Google Scholar, and ClinicalTrials.gov through June 2014 using the following keywords: nerve stimulation therapy, transcutaneous electrical nerve stimulation, back pain, chronic pain. Control treatments included sham, placebo, or medication only. Other NSTs included electroacupuncture, percutaneous electrical nerve stimulation, and percutaneous neuromodulation therapy.
RESULTS
Twelve randomized controlled trials including 700 patients were included in the analysis. The efficacy of TENS was similar to that of control treatment for providing pain relief (standardized difference in means [SDM] = -0.20; 95% confidence interval [CI], -0.58 to 0.18; P = 0.293). Other types of NSTs were more effective than TENS in providing pain relief (SDM = 0.86; 95% CI, 0.15-1.57; P = 0.017). Transcutaneous electrical nerve stimulation was more effective than control treatment in improving functional disability only in patients with follow-up of less than 6 weeks (SDM = -1.24; 95% CI, -1.83 to -0.65; P < 0.001). There was no difference in functional disability outcomes between TENS and other NSTs.
CONCLUSIONS
These results suggest that TENS does not improve symptoms of lower back pain, but may offer short-term improvement of functional disability.

Meta-Analysis
BACKGROUND
Epidural analgesia is associated with intrapartum hyperthermia, and chorioamnionitis is associated with neonatal brain injury. However, it is not known if epidural hyperthermia is associated with neonatal brain injury. This systematic review and meta-analysis investigated three questions: (1) does epidural analgesia cause intrapartum hyperthermia, (2) is intrapartum hyperthermia associated with neonatal brain injury, and (3) is epidural-induced hyperthermia associated with neonatal brain injury?
METHODS
PubMed, ISI Web of Knowledge, The Cochrane Library, and Embase were searched from inception to January 2020 using Medical Subject Headings (MeSH) terms relating to epidural analgesia, hyperthermia, labour, and neonatal brain injury. Studies were reviewed independently for inclusion and quality by two authors (Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach). Two meta-analyses were performed using the Mantel-Haenszel fixed effect method to generate odds ratios (ORs) and 95% confidence intervals (CIs).
RESULTS
Forty-one studies were included for Question 1 (646 296 participants), 36 for Question 2 (11 866 021 participants), and two studies for Question 3 (297 113 participants). When the mode of analgesia was randomised, epidural analgesia was associated with intrapartum hyperthermia (OR: 4.21; 95% CI: 3.48-5.09). There was an association between intrapartum hyperthermia and neonatal brain injury (OR: 2.79; 95% CI: 2.54-2.3.06). It was not possible to quantify the association between epidural-induced hyperthermia and neonatal brain injury.
CONCLUSIONS
Epidural analgesia is a cause of intrapartum hyperthermia, and intrapartum hyperthermia of any cause is associated with neonatal brain injury. Further work is required to establish if epidural-induced hyperthermia is a cause of neonatal brain injury.

Meta-Analysis
OBJECTIVE
To provide evidence for medical management of tinnitus based on an assessment of the evidence concerning the effectiveness of acupuncture as a treatment for tinnitus using network meta-analysis (NMA).
METHODS
We conducted a systematic literature review by searching 8 national and international databases (inception to February 2023) for randomized controlled trials (RCTs) for tinnitus. Only RCTs that recruited participants aged over 18 and diagnosed with tinnitus, and that evaluated acupuncture or acupuncture in combination with conventional western medical therapy were included. We used response rate and tinnitus handicap inventory (THI) to examine efficacy. We conducted NMA with random effects, and the rate ratio or mean difference with its 95% credible interval was calculated. In addition, we ranked all treatments via their SUCRA and assessed the quality of evidence according to the GRADE criteria.
RESULTS
A total of 2575 patients were included in the study. The main findings of the current NMA were that acupoint injection combined with warm acupuncture was the most effective for response rate, followed by warm acupuncture and acupoint injection combined with western medical treatment. Acupuncture combined with western medical treatment was the most effective for THI, followed by electroacupuncture combined with warm acupuncture and acupuncture combined with moxibustion.
CONCLUSION
Acupuncture seems to be a better trend treatment for tinnitus. Further rigorous RCT studies that include direct comparisons for different acupuncture-related treatments are encouraged to provide the most promising evidence for patients with tinnitus.

Meta-Analysis
BACKGROUND
Opioid-based general anesthesia was previously used to alleviate perioperative pain; however, several complications associated with using anesthesia have raised several concerns. Various studies have investigated the application prospect of using opioid-free general anesthesia, such as dexmedetomidine, as an opioid substitute.
OBJECTIVES
We performed a systematic review and meta-analysis to explore and highlight the safety and effectiveness of dexmedetomidine as an opioid substitute for opioid-free anesthesia.
STUDY DESIGN
A systematic review and meta-analysis.
SETTING
We screened for suitable clinical trials from electronic databases, including "PubMed," "Cochrane Library," "EMBASE," and "Web of Science." Eligible trials were included in this meta-analysis.
METHODS
The quality of the screened randomized controlled trials (RCTs) was determined using the risk of bias assessment criteria by the Cochrane Collaboration tool. We used the "Review Manager 5.3" and "Stata 10.0" software to perform the meta-analysis. We evaluated the quality of evidence using the "Grading of Recommendations Assessment, Development, and Evaluation" approach.
RESULTS
For the analysis, we included 32 RCTs encompassing 2,509 patients. In the opioid-free group, the 2-hour postoperative pain score of patients (mean difference = -0.53, 95% CI: -1.00, -0.07; P = 0.02, I2=78%) was significantly lower compared to those in the opioid-based group. In addition, several patients required rescue analgesia (risk ratio = 0.70, 95% CI: 0.58, 0.84, P < 0.05, I2 = 71%) and opioids postsurgery. However, the duration of extubation and postanesthesia care unit, as well as the incidences of bradycardia, were high in patients receiving dexmedetomidine as opioid-free general anesthesia.
LIMITATIONS
Subgroup analysis for different anesthesia-maintaining drugs had not been conducted. The heterogeneity did not reduce after subgroup analysis. Different doses of dexmedetomidine had not been evaluated.
CONCLUSIONS
These findings indicate that opioid-free general anesthesia based on dexmedetomidine could be effective; however, prolonged extubation time and cardiovascular complications are a few risks associated with dexmedetomidine.

Meta-Analysis
INTRODUCTION
This review and meta-analysis of randomized controlled trials (RCTs) assessed the side effects and efficacy of esketamine combined with propofol in procedural sedation and analgesia.
EVIDENCE ACQUISITION
The PubMed, MEDLINE, Embase and Cochrane Library databases were searched for relevant studies occurring between their inceptions and September 2022. The primary outcome was the incidence of sedation-related adverse events. Secondary outcomes included recovery time, total consumption of propofol and body movement.
EVIDENCE SYNTHESIS
Data from a total of seven RCTs enrolling 808 patients were included in the meta-analysis. Pooling of data showed that compared with other drug regimens, the esketamine and propofol combination was associated with a reduction in the risk of hypotension (relative risk [RR]: 0.37, 95% confidence interval [CI]: 0.25 to 0.56) and bradycardia (RR: 0.34, 95% CI: 0.15 to 0.80) as well as an increase in the risk of agitation (RR: 6.29, 95% CI: 1.15 to 34.32). The results also indicated a decrease in propofol consumption (standardized mean difference: -1.45, 95% CI: -2.39 to -0.50) with the use of the esketamine and propofol combination. No significant difference was observed between the two groups in respiratory depression, nausea/vomiting, recovery time or body movement.
CONCLUSIONS
Esketamine combined with propofol has an advantage in reducing the incidence of hypotension and bradycardia during procedural sedation and analgesia, but it may increase the risk of agitation in the recovery phase. More studies of high quality are needed before the widespread adoption of the combination of esketamine and propofol.

Review
INTRODUCTION
Sickle cell disease causes chronic haemolytic anaemia, dactylitis, and painful acute crises, and increases the risk of stroke, organ damage, bacterial infections, and complications of blood transfusion. In sub-Saharan Africa, up to a third of adults are carriers of the defective sickle cell gene, and 1-2% of babies are born with the disease.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of pharmaceutical and non-pharmaceutical interventions to prevent sickle cell crisis and other acute complications in people with sickle cell disease? What are the effects of pharmaceutical and non-pharmaceutical interventions to treat pain in people with sickle cell crisis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2007 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 38 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: acupuncture, antibiotic prophylaxis in children under 5 years of age, aspirin, avoidance of cold environment, blood transfusion, codeine, corticosteroid (with narcotic analgesics), diflunisal, hydration, hydroxyurea, ibuprofen, ketorolac, limiting physical exercise, malaria chemoprophylaxis, morphine (controlled-release oral after initial intravenous bolus, repeated intravenous doses), oxygen, paracetamol, patient-controlled analgesia, penicillin prophylaxis in children over 5 years of age, piracetam, pneumococcal vaccines, rehydration, and zinc sulphate.

Meta-Analysis
Effects of dexmedetomidine as an adjuvant to ropivacaine or ropivacaine alone on duration of postoperative analgesia: A systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
Ropivacaine is a long-acting local anesthetic that is used to treat postoperative pain. Adjuvant use of dexmedetomidine in regional anesthesia may prolong the duration of analgesia. The objective of this systematic review and meta-analysis was to investigate the duration and effect of ropivacaine alone vs. ropivacaine in combination with dexmedetomidine for postoperative analgesia.
METHODS
The PubMed, EMBASE, Web of Science, and Google Scholar databases were searched for randomized controlled trials (RCTs) of ropivacaine alone or ropivacaine in combination with dexmedetomidine for regional anesthesia. The primary outcome was duration of analgesia, defined as the time from onset of the block to the time of the first analgesic request or initial pain report. Secondary outcomes were duration of sensory block, duration of motor block, consumption of sufentanil for analgesia, length of hospital stay, and incidence of postoperative nausea and vomiting.
RESULTS
Eighteen studies with 1148 patients were included. Overall quality of the RCTs, as assessed by the Jadad scale, was high. The meta-analysis demonstrated that ropivacaine combined with dexmedetomidine significantly prolonged the duration of postoperative analgesia from local anesthetics compared to ropivacaine alone (WMD: 4.14h; 95%CI: 3.29~5.0h; P<0.00001; I2 = 99%). There was evidence of high heterogeneity between studies. The duration of sensory and motor block was significantly increased, and consumption of sufentanil for analgesia and the incidence of postoperative nausea and vomiting were significantly reduced in patients who received ropivacaine combined with dexmedetomidine compared to ropivacaine alone. There was no significant difference in length of hospital stay.
CONCLUSIONS
Compared to ropivacaine alone, ropivacaine combined with dexmedetomidine significantly prolonged the duration of postoperative analgesia and sensory and motor block, and reduced consumption of sufentanil for analgesia and the incidence of postoperative nausea and vomiting, across an array of surgeries.

Meta-Analysis Review
OBJECTIVES
There are long-held concerns that analgesia in patients with acute abdominal pain may obscure the physical examination and lead to missing a diagnosis of appendicitis. Despite evidence to the contrary, analgesia continues to be underutilized and suboptimally dosed in children with acute abdominal pain. The objective of this systematic review and meta-analysis was to determine if opioids provide analgesia without an increase in side effects and appendicitis-related complications.
METHODS
Trials were identified through electronic searches of MEDLINE (1946-2013), EMBASE (1980-2013), Cochrane Central Register of Controlled Trials (2013), CINAHL (1981-2013), and Google Scholar (2013). All randomized controlled trials (RCTs) of children aged 0-18 years with acute abdominal pain that compared any opioid analgesic to placebo were included. The methodologic qualities of studies and the overall quality of evidence were evaluated using the Cochrane Collaboration's Risk of Bias tool and the Grading of Recommendations Assessment, Development, and Evaluation system, respectively.
RESULTS
Six RCTs met inclusion criteria, and each compared a single-dose parenteral opioid to a placebo, providing data on 342 children aged 5 to 18 years. The pooled mean pre/post difference in self-reported pain scores was 19.61 mm (95% confidence interval [CI] = -1.16 to 40.37 mm) lower in those receiving opioid analgesia. There was no significant increase in the risk of perforation or abscess associated with opioids in cases of appendicitis (relative risk [RR] = 1.03, 95% CI = 0.55 to 1.93). The risk of side effects was significantly greater in patients who received opioids (RR = 6.06, 95% CI = 1.10 to 33.49). Subtherapeutic dosing of opioids was detected in all six trials.
CONCLUSIONS
The use of opioids in undifferentiated acute abdominal pain in children is associated with no difference in pain scores and an increased risk of mild side effects. However, there is no increased risk of perforation or abscess. The overall quality of evidence is low, suggesting the need for larger, high-quality trials that are powered to detect both serious complications of appendicitis and determine the most efficacious opioid dosing for children.
