Is Ultrasound-guided or Landmark-guided Intra-articular Lidocaine Injection More Effective for Pain Control in Anterior Shoulder Dislocation Reduction? A Randomized Controlled Trial.

Effective pain control during reduction of shoulder dislocation is essential for patient comfort. However, there is a lack of comprehensive research comparing the efficacy of different pain management techniques, specifically landmark-guided and ultrasound-guided intra-articular analgesic injections. Among patients undergoing closed reduction of a shoulder dislocation, were there differences between an intra-articular shoulder injection placed using anatomic landmarks and an ultrasound-guided intra-articular injection in terms of (1) pain before versus after the injection and pain before injection versus after the reduction, or (2) length of stay in the emergency department and complications of the procedure? Between August 2021 and March 2023, 28 patients with anterior shoulder dislocation were treated at the emergency department of a tertiary referral care center. They were randomly assigned to either the landmark-guided or ultrasound-guided intra-articular lidocaine injection group. Differences in pain levels between preinjection and postinjection, preinjection and postreduction, length of hospital stay, and complications were assessed and compared between the two groups. Patients were followed for 2 weeks. There were no between-group differences in terms of age, gender, baseline pain score, and any other relevant factors. There were no differences between the groups in terms of pain reduction between preinjection and postinjection (landmark-guided: ΔVAS 2.8 ± 1.1, ultrasound-guided: ΔVAS 2.9 ± 1.0, mean difference -0.14 [95% confidence interval -0.97 to 0.68]; p = 0.72) or between preinjection and postreduction (landmark-guided: ΔVAS 6.6 ± 2.1, ultrasound-guided: ΔVAS 5.8 ± 1.8, mean difference 0.79 [95% CI -0.74 to 2.31]; p = 0.30). There were no differences in length of stay in the emergency department (landmark-guided: 162 ± 38 minutes, ultrasound-guided: 184 ± 73 minutes, mean difference 22 minutes [95% CI -67 to 24]; p = 0.33), and no complications were reported in either group during the 2-week follow-up period. The results of the landmark-guided technique were not different from those of ultrasound-guided injection in terms of lower pain levels, length of stay, and complications. These findings provide valuable guidance for orthopaedic surgeons, enabling them to make informed decisions based on their expertise and available resources. Level I, therapeutic study.

Austere Diagnosis and Reduction of Anterior Shoulder Dislocations: 10-Year Review of a Ski Patrol-Based Program with Emergency Medical Technicians

Glenohumeral dislocations present a challenging management dilemma in austere settings where patient transport time may be prolonged. Expeditious reduction is preferable, but treatment is commonly expected to take place within a hospital or comparable facility. Through a novel shoulder injury program, professional ski patrollers trained as emergency medical technicians (EMTs) have diagnosed and reduced anterior shoulder dislocations using biomechanical techniques without sedation or analgesia for over 20 y. Summary records have been maintained to track the performance and safety of this program. Five hundred forty-six records of winter sports-related shoulder injuries from 2009-10 to 2019-20 were retrospectively analyzed to determine the assessment performance and dislocation reduction efficacy of EMTs, with the intent of ascertaining whether EMT-trained practitioners can reliably and safely diagnose and reduce anterior shoulder dislocations without premedication in a remote and resource-limited setting. EMTs identified anterior shoulder dislocations with 98% sensitivity and 96% diagnostic accuracy. The overall success rate of reduction attempts was 86%, or 88% when limited to confirmed anterior dislocations. Two fracture-dislocations and 4 misdiagnoses were manipulated. No instances of iatrogenic harm were identified, and no patients who underwent successful reductions required ambulance transportation. With appropriate education and within a structured program, EMT-trained practitioners can reliably and safely diagnose and reduce anterior shoulder dislocations using biomechanical techniques without premedication in remote and resource-limited environments. Implementation of similar programs in austere settings has the potential to improve patient care. Further, using biomechanical reduction techniques may reduce reliance on procedural sedation irrespective of care setting.

Successful Glenohumeral Shoulder Reduction With Combined Suprascapular and Axillary Nerve Block

BackgroundAnterior glenohumeral dislocation is a common injury seen in the emergency department (ED) that sometimes requires procedural sedation for manual reduction. When compared with procedural sedation for dislocation reductions, peripheral nerve blocks provide similar patient satisfaction scores but have shorter ED length of stays. In this case report, we describe the first addition of an ultrasound-guided axillary nerve block to a suprascapular nerve block for reduction of an anterior shoulder dislocation in the ED. Case ReportA 34-year-old man presented to the ED with an acute left shoulder dislocation. The patient was a fit rock climber with developed muscular build and tone. An attempt to reduce the shoulder with peripheral analgesia was unsuccessful. A combined suprascapular and axillary nerve block was performed with 0.5% bupivacaine, allowing appropriate relaxation of the patient's musculature while providing excellent pain control. The shoulder was then successfully reduced without procedural sedation. Why Should an Emergency Physician Be Aware of This?Procedural sedation for reduction of anterior shoulder dislocations is time consuming, resource intensive, and can be risky in some populations. The addition of an axillary nerve block to a suprascapular nerve block allows for more complete muscle relaxation to successfully reduce a shoulder dislocation without procedural sedation.

INTRA-ARTICULAR LIGNOCAINE AS ANALGESIA DURING MANUAL REDUCTION OF ACUTE ANTERIOR SHOULDER DISLOCATION: AN OBSERVATIONAL STUDY.

Background:Acute anterior shoulder dislocation needs prompt reduction to provide pain relief. The ideal reduction method should be simple, fast, effective and non- traumatic, with minimal pain, and should not cause further injury to the affected shoulder. Intra-articular lignocaine has been advocated as a means of providing analgesia and subsequent relaxation to the patient.Aim: To assess the efciency of intraarticular lignocaine for reduction of anterior shoulder dislocations. Patients s & Methods: Thirty cases of acute anterior shoulder dislocation were reduced using intraarticular local lignocaine injection as a method of analgesia by Rockwood's traction and counter traction method. Ten to Fifteen ml of 1% lignocaine was injected into the glenohumeral joint through a 20 gauge, 35-mm needle. Approximately ten to fteen minutes were allowed for the local anaesthetic to take effect before any manipulation of the shoulder was attempted. Results: The mean age was 37.2years±18.23 SD with majority of patients in age group of 20 to 40 years. 80% of patients were females. Among thirty patients studied 28 (93.3 %) had primary dislocation and in 18 patients (60 %) dominant shoulder was dislocated. Majority of the dislocations were reduced within 6 hours of injury. Pain assessed through application of a Visual Analog Scale during the maneuver revealed scores ranging from two to eight with mean score of 4.39 ± 1.46 SD (p value 0.049). Conclusion: We conclude method is not only safe and effective but also reduces hospital stay and has negligible adverse effects making it a popular choice for most orthopedists.

Intra-articular lidocaine versus intravenous sedation for closed reduction of acute anterior shoulder dislocation in the emergency department: a systematic review and meta-analysis.

ObjectiveAnterior shoulder dislocations are commonly treated in the emergency department (ED). Analgesia for reduction is provided by intra-articular lidocaine (IAL) injection or intravenous sedation (IV sedation). The objective of this systematic review and meta-analysis was to compare IAL versus IV sedation for closed reduction of acute anterior shoulder dislocation in the ED.MethodsElectronic searches of MEDLINE and EMBASE (1946–September 2021) were completed and reference lists were hand-searched. Randomized controlled trials (RCTs) comparing IAL and IV sedation for reduction of acute anterior shoulder dislocations among patients ≥ 15 years old in the ED were included. Outcomes of interest included a successful reduction, adverse events, ED length of stay, pain scores, procedure time, ease of reduction, patient satisfaction, and cost. Two reviewers independently screened abstracts, assessed study quality and extracted data. Data were pooled using random-effects models and reported as mean differences and risk ratios (RR) with 95% confidence intervals (CIs).Results12 RCTs were included with a total of 630 patients (IAL = 327; IV sedation = 303). There was no difference in reduction success between IAL and IV sedation (RR 0.93; 95% CI 0.86–1.01, I2 = 69%), significantly lower adverse events with IAL (RR 0.16; 95% CI 0.07–0.33, I2 = 0%), shorter ED length of stay with IAL (mean difference − 1.48; 95% CI − 2.48 to − 0.47, I2 = 93%), no difference in pain scores post-analgesia and no difference in ease of reduction.ConclusionsIntra-articular lidocaine may have similar effectiveness as IV sedation in the successful reduction of anterior shoulder dislocations in the ED with fewer adverse events, shorter ED length of stay, and no difference in pain scores or ease of reduction. Intra-articular lidocaine may be an effective alternative to IV sedation for reducing anterior shoulder dislocations, particularly when IV sedation is contraindicated or not feasible.Supplementary InformationThe online version contains supplementary material available at 10.1007/s43678-022-00368-z.

Comparative efficacy of sedation or analgesia methods for reduction of anterior shoulder dislocation: A systematic review and network meta-analysis.

We performed a network meta-analysis (NMA) to compare the efficacy and safety of intravenous sedation (IVS), intraarticular anesthetic injection (IAA), and peripheral nerve block (PNB) as sedation or analgesia methods for the reduction of anterior shoulder dislocation. We included randomized controlled trials (RCTs) comparing different sedation or analgesia methods for anterior shoulder dislocation reduction. The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, ICTRP, ClinicalTrials.gov, and Google Scholar databases were searched in October 2021. We conducted a random-effects NMA within a frequentist framework. We evaluated the confidence in each outcome using the CINeMA tool. Sixteen RCTs (957 patients) were included. Regarding the primary outcomes, the three methods might result in little to no difference in the immediate success rate of reduction and patient satisfaction. The IAA method had a shorter emergency department length of stay than that of the IVS method (mean difference [MD] -107.88 min, 95% confidence interval [CI] -202.58 to -13.18). In the secondary outcomes, the IAA method had a lower pain score than that of the PNB method (standardized MD -1.83, 95% CI -3.64 to -0.02). The IAA and PNB methods might require a longer time for reduction than that of the IVS method (MD 5.3 min, 95% CI 2.4 to 10.36; MD 15.25, 95% CI 5.49 to 25.01). The three methods might result in little to no difference in the number of reduction attempts and total success rate of reduction. However, the confidence ratings for all treatment comparisons were very low. IAA and PNB had no adverse respiratory events. The results of our NMA indicated that three sedation or analgesia methods (IVS, IAA, and PNB) might result in little to no difference in the success rate of reduction and patient satisfaction. IAA and PNB had no adverse respiratory events.

Ultrasound-Guided Retroclavicular Approach to the Infraclavicular Region (RAPTIR) Brachial Plexus Block for Anterior Shoulder Reduction

BackgroundShoulder dislocations are a common presenting injury to the emergency department (ED), with anterior dislocations comprising the majority of these cases. Some patients may tolerate gentle manipulation and reduction, but many require analgesia of some type. Oral or parenteral pain medication is often used alone or in combination with procedural sedation if gentle manipulation fails to achieve reduction. Recently, this treatment algorithm has grown to include regional anesthesia as a mode of analgesia for reduction of shoulder dislocations in the form of brachial plexus blocks. It has been well described that the interscalene and supraclavicular approach to the brachial plexus can be used to assist in reduction of anterior shoulder dislocations; however, there has yet to be any published literature regarding the use of ultrasound-guided retroclavicular approach to the infraclavicular region (RAPTIR) brachial plexus blocks for shoulder reduction.Case Report: We describe three patients who presented to the ED with anterior shoulder dislocations. The RAPTIR block was performed, provided effective analgesia, and facilitated successful shoulder reduction in all three patients.Why Should an Emergency Physician Be Aware of This? The RAPTIR nerve block is a safe and effective option for analgesia in the patient with an anterior shoulder dislocation. It may have advantages over other brachial nerve blocks and avoids the risks and disadvantages of procedural sedation and opioids.

Success rate of anterior shoulder dislocation reduction by emergency physicians: a retrospective cohort study.

AimEmergency physicians (EPs) often treat anterior shoulder dislocation, but epidemiology of anterior shoulder dislocation in the emergency department of Japan remains unclear. In this study, we clarified the success rate of anterior shoulder reduction performed by EPs.MethodsThis single‐center cohort study included patients with anterior shoulder dislocation for whom the EP performed initial reduction. The period was from January 2006 to March 2021 and we used the electronic medical record data of the tertiary care hospital. Our primary outcome was the success rate of the shoulder reduction performed by EP. The secondary outcome was to compare the success of reduction with the failure of the reduction.ResultsIn total, 293 eligible patients were identified. Of these patients, 244 were included in this study. The success rate of the shoulder reduction performed by EP was 92.2% (225/244). EPs failed in successfully performing reduction in 19 (7.8%) cases of anterior shoulder dislocations. The failure group was older (P = 0.017), had a higher frequency of fall down in the mechanism of dislocation (P = 0.019), used intravenous analgesics more frequently (P = 0.004), used peripheral nerve blocks more frequently (P = 0.006), and had fewer patients who did not use drugs (P = 0.002). We could not perform statical adjustment because the sample size was small.ConclusionThe success rate of the shoulder reduction performed by EPs was 92.2%. Older age might be associated with failure of shoulder reduction.

Closed Reduction of Anterior Shoulder Dislocations Performed by Ski Patrollers in the Alpine Prehospital Environment: A Retrospective Review Demonstrating Efficacy in a Canadian Ski Resort.

Shoulder dislocations are common ski hill injuries. Rapid reduction is known to improve outcomes; however, advanced providers are not always available to provide care to these patients. In 2017, nonmedical ski patrollers at Sunshine Village ski resort in Alberta, Canada, were trained to perform anterior shoulder dislocation (ASD) reductions. Program success was determined by a chart review after the 2020 ski season. This study retrospectively reviewed data on patients who presented to Sunshine Village ski patrol with a suspected ASD and who met the study inclusion criteria from November 2017 through March 2020. Data were collected from ski patrol electronic patient care records regarding general demographics, reduction technique used, analgesia administration, and reduction success rates. Ninety-six cases were available for review after exclusions. Trained nonmedical ski patrollers successfully reduced 82 of these cases, resulting in an overall reduction success rate of 89%. Sixty-three (66%) of these patients had experienced first-time dislocations. Eighty-two (87%) patients were male, with a median age of 25 y. The most used technique was the Cunningham method (75%), and analgesia was administered to 70% of patients. This retrospective study documents the results of a quality assurance review of the treatment of ASD at Sunshine Village ski resort. With a success rate of 89%, the evidence supports the conclusion that nonmedical ski patrollers can successfully perform ASD reductions. We believe training ski patrollers to reduce ASD improved patient care in our austere environment by providing early definitive treatment with a high success rate.

Self-reduction techniques taught via smartphone are effective for anterior shoulder dislocation: prospective randomized study.

To prospectively compare the effectiveness of three methods for self-assisted shoulder reduction demonstrated using a smartphone video link. Anterior shoulder dislocation is very common among young adults. Patients often seek medical assistance in the emergency department to reduce their shoulder. Many techniques for shoulder reduction had been described, some of which do not require professional assistance and can be performed by patients themselves. Patients admitted with anterior shoulder dislocation were randomized to either the Stimson, Milch or the Boss-Holtzach-Matter technique. Each patient was given a link to watch a short instructional video on his smartphone and instructed to attempt self-reduction. Success of the reduction, pain level, patient satisfaction and complications were recorded. Thestudy cohortconsisted of 58 patients (mean age was 31.6 (18-66, median = 27), 82% males, 88% right hand dominant). Success rate using Boss-Holtzach-Matter (10 of 19, 53%) and self-assisted Milch (11 of 20, 55%) were significantly higher than with the self-assisted Stimson method (3 of 19, 16%), p < 0.05. Pain levels improved from 8.4 (2-10) to 3.1 (0-10) following the reduction. Patient subjective satisfaction from the reduction attempt was 6.7 (0-10). No complications were observed. Both the Self-assisted Milch and the Boss-Holtzach-Matter techniques are ideal for reduction of anterior shoulder dislocation without medical assistance. Both methods can be successfully performed without assistance or previous education and taught using an instructional video. Level II.

77 Intra-articular Lidocaine versus Procedural Sedation for Anterior Shoulder Dislocations

Shoulder dislocations are the most common dislocations presenting to emergency departments (EDs). Due to the large groups of muscles involved, shoulder dislocation reductions are difficult to achieve for the provider if the patient's pain is not adequately controlled. There are several ways of providing anesthesia for shoulder dislocation reductions, and two of the most common are intra-articular lidocaine (IAL) injections and procedural sedation. Prior studies have found that the use of IAL is safer and results in a shorter ED length of stay (LOS) as compared to procedural sedation, but those studies used sedative medications that have fallen out of favor. The purpose of this study was to compare IAL to procedural sedation with propofol or etomidate for closed reduction of anterior shoulder dislocations. This was a single center, open label, randomized controlled trial. ED patients from 18 to 70 years old who had an anterior shoulder dislocation without an associated fracture (other than a Hill-Sachs) were eligible for enrollment. Consenting patients were randomized to either procedural sedation (with provider’s choice of propofol or etomidate) or IAL. The dose of procedural sedation medication was per provider discretion. The initial study protocol stated that patients randomized to the IAL group would receive 20mL of 1% lidocaine into the glenohumeral joint, but due to a shortage of 1% lidocaine, injections with 10mL of 2% lidocaine were also allowed. The primary outcome measure was ED LOS. Secondarily the number of attempts required for successful reduction and patient satisfaction were compared between groups. In total, 43 patients were enrolled with 23 randomized to the IAL group and 20 to the procedural sedation group. Three patients randomized to the IAL group ended up getting procedural sedation after failed attempts at reduction. In those randomized to the IAL group, the mean ED LOS was 133 minutes as compared to 124 minutes for the procedural sedation group. The difference of 9 minutes (95% CI -22 to 41) was not statistically significant (p = 0.54). Patients in the IAL group had a higher mean number of reduction attempts at 1.9 as compared to 1.2 in the procedural sedation group (difference 0.7 [95% CI 0.2 to 1.2]). The mean patient satisfaction scores were similar at 9.7 and 9.8 for the IAL and procedural sedation groups, respectively (difference 0.1 [95% CI -0.3 to 0.4]). Although this study was underpowered to detect small differences, there was no statistically significant difference in mean ED LOS or patient satisfaction for patients who received IAL for their shoulder dislocation reduction as compared to those who received procedural sedation. Patients randomized into the procedural sedation group required less number of attempts for successful reduction compared to those randomized into the IAL group.

P007: Cunningham reduction of anterior shoulder dislocation facilitated by inhaled low-dose methoxyflurane – a pilot study

Introduction: The Cunningham reduction method for anterior shoulder dislocation offers an atraumatic alternative to traditional reduction techniques without the inconvenience and risk of procedural sedation and analgesia (PSA). Unfortunately, success rates as low as 27% have limited widespread use of this method. Inhaled methoxyflurane (I-MEOF) offers a rapidly administered, minimally invasive option for short-term analgesia. We conducted a pilot study to evaluate the feasibility of studying whether I-MEOF increased success rates for atraumatic reduction of anterior shoulder dislocation. Methods: A convenience sample of 20 patients with uncomplicated anterior shoulder dislocations were offered the Cunningham reduction method supported by methoxyflurane analgesia under the guidance of an advanced care paramedic. Operators were instructed to limit their attempt to the Cunningham method. Outcomes included success rate without the requirement for PSA, time to discharge, and operator and patient satisfaction with the procedure. Results: 20 patients received I-MEOF and an attempt at Cunningham reduction. 80% of patients were male, median age was 38.6 (range 18-71), and 55% were first dislocations of that joint. 35% (8/20 patients) had reduction successfully achieved by the Cunningham method under I-MEOF analgesia. The remainder proceeded to closed reduction under PSA. All patients had eventual successful reduction in the ED. 60% of operators reported good to excellent satisfaction with the process, with inadequate muscle relaxation being identified as the primary cause of failed initial attempts. 80% of patients reported good to excellent satisfaction. Conclusion: Success with the Cunningham technique was marginally increased with the use of I-MEOF, although 65% of patients still required PSA to facilitate reduction. The process was generally met with satisfaction by both providers and patients, suggesting that early administration of analgesia is appreciated. Moreover, one-third of patients had reduction achieved atraumatically without need for further intervention. A larger, randomized study may identify patient characteristics which make this reduction method more likely to be successful.

A meta-analytic comparison of 8 methods of closed anterior shoulder dislocation reduction

Background: Anterior shoulder dislocation is a common injury, accounting for 95% of all shoulder injuries. However, many doctors and hospitals do not have a fixed protocol for the treatment of dislocations. The current study have compared 8 different techniques for shoulder dislocation reduction in this study. Methods: Eight different methods namely the Scapular Manipulation, Matsen’s Traction-Countertraction, Kocher’s, Spaso, External Rotation, Cunningham, Modified Milch, and the FARES methods were compared on the basis of efficacy, pain experienced during reduction (VAS score), and time taken for reduction. Results: The Matsen’s Traction-Countertraction method had the highest efficacy, while the Scapular Manipulation method had the least VAS scoring. The FARES Method had the fastest reduction time on average. Interpretation and Conclusions: As per the data analyzed, the FARES and Scapular Manipulation method appear to be the most effective in reducing anterior dislocations, having consistently high success rates, and low VAS scores and reduction times. These 2 methods may be recommended to new practitioners to treat acute shoulder dislocations.

Reducing shoulder dislocation without anaesthesia or assistant: Validation of a new reduction manoeuvre

PurposeShoulder dislocation comprises 60% of all major joint dislocations worldwide and a number of reduction techniques are described in the literature with varying degrees of success. The description of a large number of techniques speaks for itself that no method is effective all the times and one should be acquainted with more than one technique. An ideal method of reduction should be simple, easily reproducible, relatively painless that can be performed unassisted without sedation or anaesthesia with minimal or no further complications. We report our results of using a novel method of anterior shoulder reduction described recently in the literature that claims to fulfil most of the characteristics of an ideal method if not all. MethodsThis prospective study was conducted in a tertiary care centre. All the cases of primary anterior shoulder dislocation presenting within three days of injury without any associated fracture or spine trauma with or without greater tuberosity fracture were included. The reduction was done using a novel method by orthopaedic residents in all cases. The need for a second reduction attempt or anaesthesia was considered a treatment failure. Time taken for reduction, pain felt during reduction and complications if any were noted. ResultsThere were 47 (77.04%) males and 14 (22.95%) females with a mean age of (37.04 ± 12.63) years. The new technique was effective in locating a shoulder dislocation on the first attempt in 58 of the 61 dislocated shoulders (95.08%). The remaining three shoulders were reduced on second attempt by the same technique. Sedative, pre-medication or anaesthesia was not used in any case. The average time taken for the shoulder reduction was (130.5 ± 25.8) seconds and confidence interval (95%) 124–137 s. Iatrogenic complications were not seen in any of the patients. ConclusionThis relatively painless technique of shoulder reduction is easy to acquire and practice in emergency department. The advantages of this manoeuvre and its associated safety may justly lead surgeons to select it as their primary method for reduction of anterior shoulder dislocations.

Remifentanil versus Propofol/Fentanyl Combination in Procedural Sedation for Dislocated Shoulder Reduction; a Clinical Trial.

Procedural sedation and analgesia (PSA) is a fundamental skill for every emergency physician. This study aimed to compare the PSA characteristics of remifentanil with propofol/fentanyl combination. In this double-blind randomized clinical trial, the procedural characteristics and number of failures, as well as adverse events were compared between groups treated with either remifentanil or propofol/fentanyl combination consisting of 15-60 year old patients referring to emergency department following acute anterior shoulder dislocation. 64 patients were randomly assigned to either remifentanil (32 cases) or propofol/fentanyl, (32 cases) groups. The two groups were similar regarding mean age, sex, and pain severity at the time of presentation to ED. The two regimens had the same efficiency regarding pain management (100% success rate). 22 (68.8%) cases in remifentanil group and 4 (12.5%) cases in propofol/fentanyl group had failed in muscle relaxation (p < 0.001). In the group receiving remifentanil, onset of action (p = 0.043) and recovery time (p < 0.001) were significantly shorter. 10 (31.3%) cases in remifentanil group and 11 (34.4%) cases in the other group experienced adverse events (p =0.790). There was a significant difference between groups regarding the type of adverse events (p = 0.003). Compared to propofol/fentanyl combination, remifentanil has equal efficiency in pain management, lower success rate in muscle relaxation, significantly higher frequency of apnea, and shorter onset of action and recovery times in PSA for reduction of anterior shoulder dislocation.

Lidocaine-Midazolam-Fentanyl Combination in Controlling Pain for Reduction of Anterior Shoulder Dislocation; a Randomized Clinical Trial.

Finding a fast-acting compound with minimal side-effects to induce a safe and efficient analgesia with short or medium duration of action is of great interest in the emergency department. The present study has been designed with the aim of comparing the effect of midazolam + fentanyl + lidocaine combination with midazolam + fentanyl + placebo in pain management of anterior shoulder dislocation reduction. The present two-arm parallel double-blind randomized controlled trial was performed on patients who presented to emergency department with anterior shoulder dislocation. Patients were randomly allocated to the 2 treatment groups of midazolam + fentanyl + placebo (double-drug group) and midazolam + fentanyl + intravenous (IV) lidocaine (triple-drug group). Then outcomes such as treatment success rate and side-effects following prescription of drugs were compared between the 2 groups. 100 patients were included in the present study (50 patients in each group; mean age of the studied patients 27.3±8.9 years; 93.0% male). Using the double-drug regimen led to 35 (70%) cases of complete analgesia, while this rate in the triple-drug group was 41 (82%) cases (p=0.16). The calculated number needed to treat was 9 cases. This means that about one in every 9 patients in treatment arm will benefit from the treatment. The most important side-effects observed included dysrhythmia (1 patient in double drug and 1 patient in triple-drug group), apnea (2 patients in each group) and SPO2<90% (2 patients in triple-drug group) (p=0.78). Number needed to harm was 25 cases. In other words, for each 25 patients treated with the triple drug regimen, 1 case of SPO2<90% is observed. Findings of the present study showed that adding IV lidocaine to IV midazolam + fentanyl drug combination does not provide additional analgesia in sedation for anterior shoulder reduction.
