Meta-Analysis Review
BACKGROUND
Drugs used in obstetric patients must accomplish two goals: efficacy and safety for both mother and fetus. Neostigmine has been co-administered epidurally and intrathecally with local anesthetics and other adjuncts in the obstetric setting. The aim of this meta-analysis was to assess the efficacy and incidence of adverse events related to the use of neostigmine in obstetric anesthesia.
METHODS
A meta-analysis of randomized-controlled human trials was conducted using the data sources Google Scholar and PubMed (updated 1 November 2014). Inclusion criteria were: random allocation to treatment; comparison of neostigmine or neostigmine with local anesthetics and/or other adjuvants versus placebo or placebo with local anesthetics and/or other adjuvants; and approval by an ethics committee.
RESULTS
The use of neostigmine as an adjuvant in neuraxial anesthesia is associated with a reduction in the dose of local anesthetic during labor analgesia and postoperative analgesia following cesarean section: mean reduction of local anesthetic (ropivacaine or bupivacaine) vs. control -4.08 (95% CI -6.7 to -1.5) mg/h (P=0.002). The risk of nausea was increased vs. control with intrathecal neostigmine (OR 8.99 [95% CI 4.74 to 17.05], P <0.001) but not with epidural neostigmine (OR 0.97 [95% CI 0.46 to 2.05], P=0.94). Use of neuraxial neostigmine was associated with a decrease in the risk of pruritus but there was no increase in the incidence of hypotension, dizziness or sedation and no effect on the incidence of abnormal fetal heart rate patterns or Apgar scores.
CONCLUSIONS
Neuraxial administration of neostigmine significantly reduces local anesthetic consumption without serious adverse side effects to the mother or fetus. However, neostigmine is only recommended for epidural administration as intrathecal use significantly increases the incidence of maternal nausea and vomiting.

Comparative Study Meta-Analysis Review
Perineural dexamethasone has gained popularity in regional anaesthesia to prolong the duration of analgesia, but its advantage over systemic administration is disputed. The objective of this meta-analysis was to compare the analgesic efficacy of both routes of administration during peripheral nerve block. The methodology followed the PRISMA statement guidelines. The primary outcome was the duration of analgesia analysed according to the type of local anaesthetic administered (bupivacaine or ropivacaine). Secondary outcomes included cumulative opioid consumption in morphine i.v. equivalents, pain scores, and complication rates (neurological complications, infection, or hyperglycaemia). Eleven controlled trials, including 914 patients, were identified. The duration of analgesia was significantly increased with perineural dexamethasone vs systemic dexamethasone by a mean difference of 3 h [95% confidence interval (CI): 1.4, 4.5 h; P=0.0001]. Subgroup analysis revealed that the duration of analgesia was increased by 21% with bupivacaine (mean difference: 4.0 h; 95% CI: 2.8, 5.2 h; P<0.00001) and 12% with ropivacaine (mean difference: 2.0 h; 95% CI: -0.5, 4.5 h; P=0.11). The quality of evidence for our primary outcome was moderate according to the GRADE system. There were no significant differences in other secondary outcomes. No neurological complications or infections were reported. Glucose concentrations were not increased when dexamethasone was injected systemically, but this outcome was reported by only two trials. There is, therefore, moderate evidence that perineural dexamethasone combined with bupivacaine, but not ropivacaine, slightly prolongs the duration of analgesia, without an impact on other pain-related outcomes, when compared with systemic dexamethasone. Injection of perineural dexamethasone should be cautiously balanced in light of the off-label indication for this route of administration.

BACKGROUND
Percutaneous kyphoplasty (PKP) has been reported to provide a favorable analgesic effect for pain caused by osteoporotic vertebral compression fractures (OVCFs). However, a systematic review demonstrated that pain relief was only reported for approximately 86% of kyphoplasty treatments.
OBJECTIVES
To explore whether an additional facet joint block (FJB) can minimize pain and improve the clinical outcome of PKP in patients with acute OVCFs.
STUDY DESIGN
Prospective study.
SETTING
All data were from Honghui Hospital in Xi'an.
METHODS
According to the inclusion and exclusion criteria, 194 patients were eventually included in our study; they were randomly divided into 2 groups of 97 patients each and treated with either PKP + FJB or PKP alone. Follow-up consultations were scheduled 1 day, 3 days, 1 week, 1 month, 3 months, and 1 year postoperatively; the demographic characteristics, related surgical information, and complications observed within both groups were recorded. The clinical evaluation parameters included the intraoperative satisfaction score, the Visual Analog Scale (VAS) score, and the Oswestry Disability Index (ODI).
RESULTS
A total of 171 patients (61 men and 110 women; age range: 62-85 years) completed the full postoperative follow-up schedule, with 83 patients in the PKP + FJB group and 88 in the PKP group. No significant differences were observed in the genders, ages, preoperative bone mineral density, surgical levels, or volume of cement injected between the 2 groups (P > 0.05, respectively). The average duration of the surgeries in the PKP + FJB group was slightly longer than that in the PKP group (35.5 ± 4.8 min vs. 31.8 ± 4.3 min; P = 0.038), and in terms of the clinical outcomes, the average intraoperative satisfaction score was significantly higher in the PKP + FJB group (8.6 ± 1.1 vs. 6.3 ± 1.3; P < 0.001). Compared with the preoperative data, significant improvements in the VAS scores of back pain and ODI were observed at each follow-up interval (P < 0.05, respectively). These scores were significantly higher in the PKP + FJB group than in the PKP group; however, this was only observed within the first month after the procedure.
LIMITATIONS
A single-center noncontrol study.
CONCLUSIONS
The addition of an FJB (which in our study involved a unique combination of ropivacaine, prednisolone, and vitamin B12) improved the short-term clinical outcome of PKP for acute OVCFs. The local anti-inflammatory and analgesic effects on the facet joints resulted in higher intraoperative satisfaction and lower VAS and ODI scores for the first postoperative month when compared with the PKP group.

Meta-Analysis Review
BACKGROUND
Childbirth may cause the most severe pain some women experience in their lifetime. Epidural analgesia is an effective form of pain relief during labour and is considered to be the reference standard. Traditionally epidural analgesia has been delivered as a continuous infusion via a catheter in the epidural space, with or without the ability for the patient to supplement the analgesia received by activating a programmable pump to deliver additional top-up doses, known as patient-controlled epidural analgesia (PCEA). There has been interest in delivering maintenance analgesic medication via bolus dosing (automated mandatory bolus - AMB) instead of the traditional continuous basal infusion (BI); recent randomized controlled trials (RCTs) have shown that the AMB technique leads to improved analgesia and maternal satisfaction.
OBJECTIVES
To assess the effects of automated mandatory bolus versus basal infusion for maintaining epidural analgesia in labour.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase, the World Health Organization International Clinial Trials Registry Platform (WHO-ICTRP) and ClinicalTrials.gov on 16 January 2018. We screened the reference lists of all eligible trials and reviews. We also contacted authors of included studies in this field in order to identify unpublished research and trials still underway, and we screened the reference lists of the included articles for potentially relevant articles.
SELECTION CRITERIA
We included all RCTs that compared the use of bolus dosing AMB with continuous BI for providing pain relief during epidural analgesia for labour in women.
DATA COLLECTION AND ANALYSIS
We used the standard methodological procedures expected by Cochrane. Our primary outcomes were: risk of breakthrough pain with the need for anaesthetic intervention; risk of caesarean delivery; risk of instrumental delivery. Secondary outcomes included: duration of labour; local anaesthetic consumption. We used GRADE to assess the certainty of evidence for each outcome.
MAIN RESULTS
We included 12 studies with a total of 1121 women. Ten studies enrolled healthy nulliparous women only and two studies enrolled healthy parous women at term as well. All studies excluded women with complicated pregnancies. There were variations in the technique of initiation of epidural analgesia. Seven studies utilized the combined spinal epidural (CSE) technique, and the other five studies only placed an epidural catheter without any intrathecal injection. Seven studies utilized ropivacaine: six with fentanyl and one with sufentanil. Two studies used levobupivacaine: one with sufentanil and one with fentanyl. Three used bupivacaine with or without fentanyl. The overall risk of bias of the studies was low.AMB probably reduces the risk of breakthrough pain compared with BI for maintaining epidural analgesia for labour (from 33% to 20%; risk ratio (RR) 0.60; 95% confidence interval (CI) 0.39 to 0.92, 10 studies, 797 women, moderate-certainty evidence). AMB may make little or no difference to the risk of caesarean delivery compared to BI (15% and 16% respectively; RR 0.92; 95% CI 0.70 to 1.21, 11 studies, 1079 women, low-certainty evidence).AMB may make little or no difference in the risk of instrumental delivery compared to BI (12% and 9% respectively; RR 0.75; 95% CI 0.54 to 1.06, 11 studies, 1079 women, low-certainty evidence). There is probably little or no difference in the mean duration of labour with AMB compared to BI (mean difference (MD) -10.38 min; 95% CI -26.73 to 5.96, 11 studies, 1079 women, moderate-certainty evidence). There is probably a reduction in the hourly consumption of local anaesthetic with AMB compared to BI for maintaining epidural analgesia during labour (MD -1.08 mg/h; 95% CI -1.78 to -0.38, 12 studies, 1121 women, moderate-certainty evidence). Five out of seven studies reported an increase in maternal satisfaction with AMB compared to BI for maintaining epidural analgesia for labour; however, we did not pool these data due to their ordinal nature. Seven studies reported Apgar scores, though there was significant heterogeneity in reporting. None of the studies showed any significant difference between Apgar scores between groups.
AUTHORS' CONCLUSIONS
There is predominantly moderate-certainty evidence that AMB is similar to BI for maintaining epidural analgesia for labour for all measured outcomes and may have the benefit of decreasing the risk of breakthrough pain and improving maternal satisfaction while decreasing the amount of local anaesthetic needed.

BACKGROUND
Critical limb ischaemia (CLI) is a severe manifestation of peripheral arterial disease, characterised by chronic ischaemic rest pain, ulcers or gangrene. Management of ischaemic pain is challenging in patients with no options for revascularisation and optimal pharmacological therapies have not been established.
OBJECTIVES
To identify and evaluate the effectiveness of pharmacological therapies to treat ischaemic pain secondary to non-reconstructable CLI.
METHODS
This systematic review was reported in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline. Comprehensive searches of three electronic databases, a PubMed-related articles link search, grey literature search and hand-searches of the bibliographies of relevant papers and textbooks were performed. Studies recruiting adult patients with CLI of any aetiology were eligible for inclusion. Surgical and revascularisation procedures, and all invasive interventions were excluded.
RESULTS
Of 792 studies, six met full inclusion criteria. These studies researched the use of intravenous lidocaine, intravenous ketamine, oral gabapentin and the combination of transdermal buprenorphine and epidural morphine/ropivacaine infusion. All studies showed an improvement in severity of ischaemic pain in CLI but with varying side effect profiles and quality. The extracted studies showed substantial heterogeneity and therefore a meta-analysis was not performed.
CONCLUSION
The pharmacological management of pain secondary to non-reconstructable CLI is a challenging review topic. No recommendations of pharmacological agents can be made following this review but a number of novel approaches to manage pain in this cohort have shown positive results and require further investigation.

Posttraumatic stress disorder (PTSD) is a chronic disorder resulting from exposure to traumatic events. In recent years, sympathetic nerve blocks have gained interest as an emerging treatment modality for PTSD. They have been shown to reduce autonomic dysfunction associated with PTSD symptoms, particularly in refractory and treatment-resistant patients. However, there is limited evidence regarding the technique's effectiveness in PTSD patients. Therefore, this scoping review was designed to update and summarize the current literature on this topic to inform the design of future clinical trials and studies. Our review of 22 studies (mostly case reports and series) included 1,293 PTSD patients who received sympathetic nerve blocks, primarily military service members and veterans, with a median age of 42.2 years. 0.5% Ropivacaine was the preferred anesthetic, and the right sided stellate ganglion block was the most commonly used technique. Relapse of symptoms was reported commonly, resulting in additional nerve block sessions. Most reported side effects were mild and transient. Despite the encouraging results, we remain cautious in interpreting the benefit of the technique due to the lack of sufficient standardized clinical trial data, heterogeneity in reported results, and the potential for bias in reporting. Future studies should focus on evaluating and addressing the technique's effectiveness, safety, tolerability, and indications.

Journal of Orthopaedics Dec 2015Chondrolysis involves the breakdown of cartilage following arthroscopic surgery, most commonly affecting the glenohumeral joint.
BACKGROUND
Chondrolysis involves the breakdown of cartilage following arthroscopic surgery, most commonly affecting the glenohumeral joint.
METHODS
This review summarises all clinical and laboratory studies regarding local anaesthetic (LA) and its association with chondrolysis. We identified 289 papers, 41 of which met our inclusion criteria and were included in the final review.
RESULTS
Bupivacaine, lidocaine, ropivacaine and levobupivacaine are all toxic to cartilage. Intra-articular infusions confer a greater toxicity to cartilage than single injections.
CONCLUSIONS
Intra-articular LA pain pumps carry a high risk of chondrolysis and should be avoided. Further studies are indicated to assess long-term single exposure LA implications.

Meta-Analysis
OBJECTIVES
Pain management for the extraction of the mandibular third molar is a challenge as compelling evidence in comparative anaesthetics is currently lacking.
MATERIALS AND METHODS
Thorough literature searches took place in PubMed, ScienceDirect, CENTRAL, Embase, Web of Science, CBM, and CNKI. Thirty-three trials were meta-analysed using a Bayesian statistical approach within the random-effects model. Grading of Recommendations Assessment, Development, and Evaluation was performed to determine the overall quality of evidence across all comparisons.
RESULTS
In terms of success rate, an inferior alveolar nerve block (IANB) injection of 2% lidocaine with epinephrine was less effective than a combined injection of buccal infiltration (BI) and lingual infiltration (LI) with a 4% articaine (RR = 0.85 [0.75, 0.96], P = 0.611). According to visual analogue scale (VAS), 2% lidocaine-IANB with epinephrine caused higher VAS scores than 4% articaine-IANB with epinephrine (MD = 0.84 [0.28, 1.40], P = 0.057), whereas 0.5% levobupivacaine-IANB showed lower scores than 2% lidocaine-IANB (MD = - 1.62 [- 2.97, - 0.28], P = 0.045). Also, 2% lidocaine-IANB with epinephrine presented longer latency than both 4% articaine-IANB with epinephrine (MD = 39.44 [16.97, 61.90], P < 0.001) and 4% articaine-BI + LI with epinephrine (MD = 164.41 [16.23, 312.58], P < 0.001); 4% articaine-IANB with epinephrine produced shorter latency than 0.5% bupivacaine-IANB with epinephrine (MD = - 42.92 [- 70.28, - 15.56], P = 0.106); 0.75% ropivacaine-IANB caused shorter onset of action compared with 2% lidocaine-IANB (MD = - 40.88 [- 65.50, - 16.26], P < 0.001). In addition, 2% lidocaine-IANB with epinephrine produced significantly shorter duration than both 4% articaine-IANB with epinephrine (MD = - 47.33 [- 57.88, - 36.77], P = 0.265) and 2% mepivacaine-IANB with epinephrine (MD = - 10.01 [- 19.59, - 0.44], P = 0.769). The duration of action triggered by 4% articaine-IANB with epinephrine was shorter compared with 0.5% bupivacaine-IANB with epinephrine (MD = - 64.17 [- 74.65, - 53.69], P = 0.926). Both 0.5% levobupivacaine-IANB and 0.75% ropivacaine-IANB produced longer duration of action than 2% lidocaine-IANB (MD = 333.70 [267.33, 400.07], P < 0.001) and (MD = 288.01 [287.67, 288.34], P = 0.634, respectively).
CONCLUSIONS
The network meta-analysis demonstrated that the intraosseous injection of 4% articaine with epinephrine had the most noteworthy success rate. However, the combination of BI and LI of 4% articaine with epinephrine, and IANB of 0.5% bupivacaine were, according to a VAS, the most effective. It should be noted that a rapid onset of action was produced by BI combined with LI of 4% articaine with epinephrine and IANB of 2% mepivacaine with epinephrine, while the most prolonged duration of action was generated by IANB of 0.5% levobupivacaine or 0.5% bupivacaine.
CLINICAL RELEVANCE
For a better understanding of local anaesthesia for the extraction of the third molar, our study was aimed to provide evidence to guide better dental practices in pain management for clinicians.

AIMS
Percutaneous stellate ganglion block (PSGB) through single-bolus injection and thoracic epidural anaesthesia (TEA) have been proposed for the acute management of refractory ventricular arrhythmias (VAs). However, data on continuous PSGB (C-PSGB) are scant. The aim of this study is to report our dual-centre experience with C-PSGB and to perform a systematic review on C-PSGB and TEA.
METHODS AND RESULTS
Consecutive patients receiving C-PSGB at two centres were enrolled. The systematic literature review follows the latest Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Our case series (26 patients, 88% male, 60 ± 16 years, all with advanced structural heart disease, left ventricular ejection fraction 23 ± 11%, 32 C-PSGBs performed, with a median duration of 3 days) shows that C-PSGB is feasible and safe and leads to complete VAs suppression in 59% and to overall clinical benefit in 94% of cases. Overall, 61 patients received 68 C-PSGBs and 22 TEA, with complete VA suppression in 63% of C-PSGBs (61% of patients). Most TEA procedures (55%) were performed on intubated patients, as opposed to 28% of C-PSGBs (P = 0.02); 63% of cases were on full anticoagulation at C-PSGB, none at TEA (P < 0.001). Ropivacaine and lidocaine were the most used drugs for C-PSGB, and the available data support a starting dose of 12 and 100 mg/h, respectively. No major complications occurred, yet TEA discontinuation rate due to side effects was higher than C-PSGB (18 vs. 1%, P = 0.01).
CONCLUSION
Continuous PSGB seems feasible, safe, and effective for the acute management of refractory VAs. The antiarrhythmic effect may be accomplished with less concerns for concomitant anticoagulation compared with TEA and with a lower side-effect related discontinuation rate.

Comparative Study Meta-Analysis
The comparison of intrathecal ropivacaine with bupivacaine for knee arthroscopy remains controversial. We conduct a systematic review and meta-analysis to explore the efficacy of intrathecal ropivacaine versus bupivacaine for knee arthroscopy. We search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through August 2019 for randomized controlled trials (RCTs) assessing the effect of intrathecal ropivacaine versus bupivacaine for knee arthroscopy. This meta-analysis is performed using the random effects model. Five RCTs are included in the meta-analysis. Overall, compared with intrathecal bupivacaine for knee arthroscopy, intrathecal ropivacaine is associated with increased onset time of motor block (mean difference [MD] = 2.05, 95% CI: 1.43-2.67, < 0.00001) and decreased duration of sensory block (MD = -26.82, 95% CI: -31.96 to -21.67, < 0.00001) but shows no remarkable influence on onset time of sensory block (MD = -0.09; 95% CI: -1.89 to 1.70, = 0.92), duration of motor block (MD = -59.76; 95% CI: -124.44 to 4.91, = 0.07), time to maximum block (MD = 2.35; 95% CI: -0.16 to 4.86, = 0.07), first urination time (MD = -26.42, 95% CI: -57.34 to 4.51, = 0.09), or first ambulation time (MD = 3.63, 95% CI: -25.20 to 32.47, = 0.80).Intrathecal ropivacaine can substantially increase onset time of motor block and decrease the duration of sensory block than intrathecal bupivacaine for knee arthroscopy.
