How Does the Addition of Dexamethasone to a Brachial Plexus Block Change Pain Patterns After Surgery for Distal Radius Fractures? A Randomized, Double-blind Study

Comparison of supraclavicular block with infraclavicular block for distal arm surgeries: A meta-analysis of randomized controlled studies

BACKGROUND

Supraclavicular and infraclavicular nerve block are commonly used for the analgesia of distal arm surgeries, and this meta-analysis aims to compare their analgesic efficacy for distal arm surgeries.

METHODS

We searched several databases including PubMed, Embase, Web of Science, EBSCO, and Cochrane library databases, and selected the randomized controlled trials exploring the analgesic efficacy of supraclavicular block versus infraclavicular block for distal arm surgeries. This meta-analysis was conducted using the random-effect or fixed-effect model based on the heterogeneity.

RESULTS

Six randomized controlled trials were included in this meta-analysis. Compared with infraclavicular nerve block for distal arm surgeries, supraclavicular nerve block was associated with substantially reduced complete sensory block (odds ratio [OR] = 0.41; 95% confidence interval [CI] = 0.19-0.88; P = .02) and block performance time (standard mean difference [SMD] = -3.06; 95% CI = -5.82--0.31; P = .03), but had no effect on duration of analgesia (SMD = -0.15; 95% CI = -0.49-0.18; P = .36), time to sensory block (SMD = -0.41; 95% CI = -2.28-1.47; P = .67), vascular puncture (OR = 1.03; 95% CI = 0.11-10.05; P = .98) or adverse events (OR = 0.70; 95% CI = 0.12-4.04; P = .69).

CONCLUSIONS

Infraclavicular nerve block may be superior to supraclavicular nerve block for the analgesia of distal arm surgeries but needs increased block performance time.

Prophylactic dexamethasone for rebound pain after peripheral nerve block in adult surgical patients: systematic review, meta-analysis, and trial sequential analysis of randomised controlled trials

BACKGROUND

Rebound pain occurs after the resolution of peripheral nerve block and hampers patient recovery in the postoperative period. We sought to synthesise available data from randomised controlled trials (RCTs) evaluating the efficacy of prophylactic dexamethasone for rebound pain in adult patients undergoing surgery with a peripheral nerve block.

METHODS

In this systematic review and meta-analysis, RCTs reporting rebound pain and use of dexamethasone in the context of a peripheral nerve block were searched in various databases and updated in May 2023. The primary outcome was the incidence of rebound pain; secondary outcomes included the severity and time to onset of rebound pain, patient satisfaction with pain control, sleep disturbance because of pain, and adverse effects of dexamethasone. Subgroup analysis was conducted based on the effect of route of administration (intravenous or perineural) on the incidence of rebound pain. Trial sequential analysis was performed to rule out the possibility of a false positive result.

RESULTS

Seven RCTs comprising 574 patients were included in this review. The dexamethasone group was associated with a reduction in the incidence of rebound pain with an odds ratio of 0.16 (95% confidence interval 0.10-0.27, P=0.00, I2=0%) compared with the control group. Trial sequential analysis confirmed the adequate information size for the beneficial effect of dexamethasone. Subgroup analysis showed that both intravenous and perineural administration were associated with a significant reduction in the incidence of rebound pain.

CONCLUSIONS

Current evidence suggests that both intravenous and perineural dexamethasone reduce the incidence of rebound pain after a peripheral nerve block provided for postoperative analgesia.

13 years of hand surgery without an anesthesiologist. An analysis of efficacy and safety of presurgical anesthesia as delivered by surgeons without the assistance of anesthesiologists

<b><br>Introduction:</b> The assistance of anaesthesiologist is considered an inseparable part of most surgical procedures, with the exception of a small proportion of minor procedures performed under local anaesthesia. In hand surgery, a vast majority of procedures, even those lasting several hours, can be carried out under regional (brachial plexus block) or local (infiltration) anaesthesia. These can be delivered by the surgeons themselves, allowing the surgeries to be carried out without the assistance of anesthesiologists.</br> <b><br>Aim:</b> The aim of this study was to analyze the efficacy and safety of presurgical anesthesia as delivered by surgeons without the assistance of anesthesiologists in the course of hand surgery procedures performed within the institution headed by the author of this article.</br> <b><br>Material and methods:</b> The analysis was based on the records of anesthesia protocols filled out by the surgeons who delivered the anesthesia and who operated on the patients. The variables considered included the efficacy of anesthesia and the anesthesia-related adverse effects and complications.</br> <b><br>Results:</b> Over a period of 13 years (2010-2022), a total of 24,703 surgeries were delivered; of these, 22,228 (91%) surgeries were carried out without anesthesiologists, with anesthesia being delivered by the surgeon him/herself. The efficacy of these procedures (local anasthesia and brachial plexus blocks combined) was 99%. A total of 631 (2.8%) anesthesia-related adverse reactions were recorded, most of them being transient, requiring immediate interventions and not leading to any serious sequelae. In only 17 cases (0.07%), adverse effects resulted in cancellation and rescheduling of the elective surgery.</br> <b><br>Conclusions:</b> Pre-surgical anesthesia as delivered prior to hand surgery procedures by the surgeons without the assistance of anesthesiologists is effective and safe while being associated with numerous benefits for patients, surgeons and the health care system's budget.</br>.
