Abstract
BACKGROUND Peripheral nerve injury or post-block neurological dysfunction (PBND) are uncommon but a recognized complications of peripheral nerve blocks (PNB). A broad range of its incidence is noted in the literature and hence a critical appraisal of its occurrence is needed. OBJECTIVE In this review, we wanted to know the pooled estimates of PBND and further, determine its pooled estimates following various PNB over time. Additionally, we also sought to estimate the incidence of PBND with or without US guidance. EVIDENCE REVIEW A literature search was conducted in six databases. For the purposes of the review, we defined PBND as any new-onset sensorimotor disturbances in the distribution of the performed PNB either attributable to the PNB (when reported) or reported in the context of the PNB (when association with a PNB was not mentioned). Both prospective and retrospective studies which provided incidence of PBND at timepoints of interest (>48 hours to <2 weeks; >2 weeks to 6 weeks, 7 weeks to 5 months, 6 months to 1 year and >1 year durations) were included for review. Incidence data were used to provide pooled estimates (with 95% CI) of PBND at these time periods. Similar estimates were obtained to know the incidence of PBND with or without the use of US guidance. Additionally, PBND associated with individual PNB were obtained in a similar fashion with upper and lower limb PNB classified based on the anatomical location of needle insertion. FINDINGS The overall incidence of PBND decreased with time, with the incidence being approximately 1% at <2 weeks' time (Incidence per thousand (95% CI)= 9 (8; to 11)) to approximately 3/10 000 at 1 year (Incidence per thousand (95% CI)= 0. 3 (0.1; to 0.5)). Incidence of PBND differed for individual PNB with the highest incidence noted for interscalene block. CONCLUSIONS Our review adds information to existing literature that the neurological complications are rarer but seem to display a higher incidence for some blocks more than others. Use of US guidance may be associated with a lower incidence of PBND especially in those PNBs reporting a higher pooled estimates. Future studies need to standardize the reporting of PBND at various timepoints and its association to PNB.

Abstract
BACKGROUND In this study, interscalene brachial plexus block (ISB) with superficial cervical plexus block added and general anesthesia (GA) application were evaluated in terms of intraoperative hemodynamics, operative time and postoperative analgesia need in patients who underwent rotator cuff tear repair. METHODS 70 patients aged between 18 and 75 years were included in this prospective study. Arthroscopic rotator cuff tear repair surgery was performed in all patients. The patients were randomized into 2 groups, namely Group ISB who received a combination of superficial cervical plexus block added to the Interscalene Nerve Block, and Group GA, for those who received GA. Duration of operation, waiting times, intraoperative hemodynamic data, postoperative visual analog scale (VAS), analgesic requirement, as well as patient and surgeon satisfaction levels, were compared between the 2 groups. RESULTS While VAS values at the post-anesthesia care unit were lower in ISB group at 2 and 24 hours (P < .05), there was no significant difference between VAS values measured at 6th and 12th hours (P ≥ .05). In the GA group, postoperative morphine and diclofenac consumption was higher, and rescue analgesia was needed earlier (P < .05). The hospital stay was shorter (P < .05), and surgeon and patient satisfaction were higher in the ISB group (P < .05). CONCLUSION SUBSECTIONS In rotator cuff tear repair anesthesia, ISB with superficial cervical plexus block provides adequate intraoperative anesthesia, low postoperative VAS level, reduced and deferred consumption of opioids and nonsteroidal anti-inflammatory drugs, higher patient and surgeon satisfaction and early discharge.

Abstract
BACKGROUND While providing effective analgesia following shoulder arthroplasty, an interscalene block has known complications. Local infiltration analgesia (LIA) using ropivacaine has been successfully employed in other joint arthroplasties, but its efficacy in shoulder arthroplasty has not been studied extensively. The purpose of this study was to compare pain and opioid consumption between LIA and an interscalene block following shoulder arthroplasty. METHODS Patients undergoing primary shoulder arthroplasty were prospectively randomized into 2 groups: the block group received an interscalene block using liposomal bupivacaine, and the injection group received an LIA injection intraoperatively. The LIA injection included ropivacaine, epinephrine, ketorolac, and normal saline solution. Postoperative visual analog scale pain scores, opioid consumption in morphine milligram equivalents, and complications were compared between the groups. The mean pain scores during the first 24 hours postoperatively were used to test noninferiority of LIA compared with an interscalene block. RESULTS The study included 74 patients (52 men and 22 women with a mean age of 69 years; 37 were in the injection group and 37 in the block group). There was no significant difference between the groups with respect to pain scores at any postoperative time points (p > 0.05), except for the 8-hour time point, when the injection group had a significantly higher pain score than the block group (p = 0.01). There was no significant difference in opioid consumption between the groups at any time points postoperatively (p > 0.05). The amount of intraoperative opioid consumption was significantly higher in the injection group (p < 0.001). In noninferiority testing for the mean pain scores during the first 24 hours, the injection group was found to be noninferior to the block group. One patient in the block group developed transient phrenic nerve palsy. One patient in the injection group developed dislocation after reverse arthroplasty related to noncompliance. The mean procedure hospital charge was $1,718 for an interscalene block and $157 for LIA. CONCLUSIONS LIA and an interscalene block provided similar analgesia during the first 24 hours after primary shoulder arthroplasty. LIA was associated with worse pain at 8 hours postoperatively and more intraoperative opioid consumption but was also substantially less costly. LEVEL OF EVIDENCE Therapeutic Level I .

Abstract
BACKGROUND Interscalene nerve block and liposomal bupivacaine have been found to provide adequate pain control following shoulder arthroplasty. We hypothesized that local infiltration of a periarticular cocktail would provide equivalent pain control compared to interscalene nerve block and liposomal bupivacaine. METHODS Eighty-seven patients undergoing primary shoulder arthroplasty were treated with local infiltration of a periarticular cocktail (200 mg of 0.5% ropivacaine, 1 mg epinephrine, and 30 mg ketorolac), local infiltration of liposomal bupivacaine, or preoperative interscalene nerve block. The outcomes of the study were postoperative visual analog scale scores, opioid consumption, length of stay, and complications. RESULTS A total of 30 patients receiving local infiltration of a periarticular cocktail, 26 receiving liposomal bupivacaine, and 31 receiving interscalene nerve block were included in the study. Patients who received local infiltration of a periarticular cocktail had a significantly lower mean visual analog scale when compared to interscalene nerve block and liposomal bupivacaine on postoperative day 0 (2.5 versus 4.0 versus 4.8, P = 0.001 and P < 0.001). Pain scores between postoperative day 0-3 were lower in patients who received local infiltration of a periarticular cocktail, but not significantly. Patients who received local infiltration of a periarticular cocktail required significantly less opioids than the interscalene nerve block group on postoperative day 0 (P < 0.001). DISCUSSION A decrease in early postoperative pain and opioid consumption was found with local infiltration of a periarticular cocktail when compared with interscalene nerve block and liposomal bupivacaine after shoulder arthroplasty.Level of evidence: Level II.

Abstract
CASE A 42-year-old previously healthy woman developed profound hypotension, bradycardia, and asystolic cardiac arrest requiring cardiopulmonary resuscitation after an interscalene block before being placed in the beach-chair position for shoulder arthroscopy. CONCLUSION Activation of the Bezold-Jarisch reflex, a vagally mediated reflex leading to hypotensive bradycardic episodes, is a rare but devastating complication of shoulder arthroscopy when performed with the combination of interscalene blocks and the beach-chair position. Our case shows that the Bezold-Jarisch reflex may occur in patients before placement in the beach-chair position and may even lead to extreme reactions in healthy patients including asystolic cardiac arrest.

Abstract
Local anesthetics are commonly administered by nuchal infiltration to provide a temporary interscalene brachial plexus block (ISB) in a surgical setting. Although less commonly reported, local anesthetics can induce central nervous system toxicity. In this case study, we present three patients with acute central nervous system toxicity induced by local anesthetics applied during ISB with emphasis on neurological symptoms, key neuroradiological findings and functional outcome. Medical history, clinical and imaging findings, and outcome of three patients with local anesthetic-induced toxic left hemisphere syndrome during left ISB were analyzed. All patients were admitted to our neurological intensive care unit between November 2016 and September 2019. All three patients presented in poor clinical condition with impaired consciousness and left hemisphere syndrome. Electroencephalography revealed slow wave activity in the affected hemisphere of all patients. Seizure activity with progression to status epilepticus was observed in one patient. In two out of three patients, cortical FLAIR hyperintensities and restricted diffusion in the territory of the left internal carotid artery were observed in magnetic resonance imaging. Assessment of neurological severity scores revealed spontaneous partial reversibility of neurological symptoms. Local anesthetic-induced CNS toxicity during ISB can lead to severe neurological impairment and anatomically variable cerebral lesions.

Abstract
Background: Anterior interosseous nerve (AIN) palsy is a very uncommon cause of upper extremity pain and weakness that comprises less than 1% of all upper extremity nerve palsies. Rarely reported but also mentioned in the literature is AIN palsy after shoulder arthroscopy. Methods: A systematic review of the literature to date using PubMed was conducted to identify patients who suffered AIN palsy after shoulder arthroscopy procedures. Articles included met the following criteria: (1) published in English; (2) primary presentation of the data; (3) patients had undergone shoulder arthroscopy before developing symptoms of AIN palsy; and (4) diagnosis was confirmed with clinical symptoms of AIN palsy. Measured outcomes included patient demographics, specific shoulder procedure, anesthesia procedure, intra-operative patient positioning, intra-operative compressive dressing, intra-operative traction, surgical versus conservative treatment, abnormal findings during decompression procedure, proposed mechanism of injury, and follow-up. Results: The search yielded 6 articles, of which 4 (13 cases) met inclusion criteria. An additional 2 cases were included in this report totaling 15 cases. The average patient age was 49 years (range: 31-64) with 73% males. At average follow-up of 24 months, 67% of patients experienced complete resolution of symptoms-more than half of which underwent surgical decompression. Patients who failed to progress experienced weakness of the flexor digitorum profundus and flexor pollicis longus muscles. Conclusions: Proposed injury mechanisms for AIN palsy after shoulder arthroscopy range from mechanical trauma, compressive hematoma, and direct anesthetic neurotoxicity. Management should be directed by clinical symptoms, imaging, and patient factors with majority of patients expected to have excellent clinical outcomes.

Abstract
Ultrasound-guided interscalene block (US-ISB) and nerve stimulator-guided interscalene block (NS-ISB) have both been commonly used for anesthesia in shoulder arthroscopic surgery.This study aims to compare which method provides surgical block as a sole anesthesia. In this retrospective study, 1158 patients who underwent shoulder arthroscopic rotator cuff tear repair surgery under ISB between October 2002 and March 2018 were classified into either the US-ISB or NS-ISB anesthesia groups. Demographic and anesthetic characteristics and intraoperative medications were analyzed after propensity score matching and compared between the 2 groups.There was a 0.5% rate of conversion to general anesthesia in the US-ISB group and a 6.7% rate in the NS-ISB group (P < .001). The volume of local anesthetics used for ISB was 29.7 ± 8.9 mL in the US-ISB group versus 38.1 ± 4.8 mL in the NS-ISB group (P < .001). The intraoperative use of analgesics and sedatives such as fentanyl, midazolam and propofol in combination was significantly lowered in the US-ISB group (P < .001).US-ISB is a more effective and safer approach for providing intense block to NS-ISB because it can decrease the incidence of conversion to general anesthesia and reduce the use of analgesics and sedatives during arthroscopic shoulder surgery.

Impact of Regional Block Failure in Ambulatory Hand Surgery on Patient Management: A Cohort Study. J Clin Med 2020; 9:jcm9082453.

Abstract
Regional anesthesia (RA) is an anesthetic technique essential for the performance of ambulatory surgery. Failure rates range from 6% to 20%, and the consequences of these failures have been poorly investigated. We determined the incidence and the impact of regional block failure on patient management in the ambulatory setting. This retrospective cohort study includes all adult patients who were admitted to a French University Hospital (Hôpital Saint-Antoine, AP-HP) between 1 January 2016 and 31 December 2017 for unplanned ambulatory distal upper limb surgery. Univariate and stepwise multivariate analyses were performed to determine factors associated with block failure. Among the 562 patients included, 48 (8.5%) had a block failure. RA failure was associated with a longer surgery duration (p = 0.02), more frequent intraoperative analgesics administration (p < 0.01), increased incidence of unplanned hospitalizations (p < 0.001), and a 39% prolongation of Post-Anesthesia Care Unit (PACU) length of stay (p < 0.0001). In the multivariate analysis, the risk factors associated with block failure were female sex (p = 0.04), an American Society of Anesthesiologists (ASA) score > 2 (p = 0.03), history of substance abuse (p = 0.01), and performance of the surgery outside of the specific ambulatory surgical unit (p = 0.01). Here, we have documented a significant incidence of block failure in ambulatory hand surgery, with impairment in the organization of care. Identifying patients at risk of failure could help improve their management, especially by focusing on providing care in a dedicated ambulatory circuit.

A prospective study of two methods of analgesia in shoulder arthroscopic procedures as day case surgery. J Clin Orthop Trauma 2020; 11:S368-S371.

Abstract
BACKGROUND & PURPOSE The recent advances in anaesthesia and analgesia have significantly improved the early recovery and effective post-operative pain control in day care surgery e.g. shoulder arthroscopic procedures. Adequate analgesia improves the early rehabilitation for a better outcome. We prospectively evaluated the post-operative pain relief following the two methods of analgesia i.e. regional Inter-scalene block (ISB) vs Intra-articular (IA) injection using 0.5% Chirocaine in various therapeutic arthroscopic shoulder procedures. METHODS A prospective comparative study was performed on a group of 105 patients (ASA grade I or II) who underwent the following procedures at two different hospitals: diagnostic arthroscopy, subacromial decompression (SAD) alone, SAD in combination with mini open cuff repairs or distal clavicle excision, anterior stabilization (Bankart's repair) and inferior capsular shift. A successful Inter-scalene block (0.5% Chirocaine-30mls) preceded the general anaesthesia (Group 1-52 patients). Local intra-articular infiltration (0.5% Chirocaine - 20 mls) was given postoperatively (Group 2-53 patients). Post operatively visual analogue scores (VAS) from 0 (no pain) to 10 (severe pain) were assessed in post-anaesthesia care unit (PACU), at 4hrs, at 24hrs and at 48 h. The amount of morphine consumption for the first 2 days after surgery was recorded. RESULTS Patient characteristics were similar in both groups at both the hospitals. The median postoperative pain score of VAS <3 was observed in both groups. Significant difference (p < 0.0001) was observed in the VAS scores between the two groups at all the time intervals. The mean length of adequate sensory block in group 1 was significantly higher than in group 2 [20.5 h: 4.2 h] (p < 0.001). The mean analgesic (morphine) consumption was lower in Group 1 as compared to Group 2 [4.6 mg/24 h: 18.8mg/24 h](p < 0.0001). Bone shaving procedures e.g. SAD, SAD + Rotator Cuff repair, SAD + Lateral clavicular excision required significantly higher analgesia in both groups compared to the soft tissue procedures. CONCLUSION Single dose ISB provided longer and effective postoperative analgesia. The bone shaving procedures required more analgesia in IA Group as compared to ISB Group.

Abstract
Background Optimal modalities for pain control in shoulder arthroplasty are not yet established. Although regional nerve blockade has been a well-accepted modality, complications and rebound pain have led some surgeons to seek other pain control modalities. Local injection of anesthetics has recently gained popularity in joint arthroplasty. The purpose of this study was to evaluate the effectiveness and complication rate of a low-cost local anesthetic injection mixture for use in total shoulder arthroplasty (TSA) compared with interscalene brachial plexus blockade. Methods A total of 314 patients underwent TSA and were administered general anesthesia with either a local injection mixture (local infiltration anesthesia [LIA], n = 161) or peripheral nerve block (PNB, n = 144). Patient charts were retrospectively reviewed for postoperative pain scores, 24-hour opioid consumption, and 90-day postoperative complications. Results Immediate postoperative pain scores were not significantly different between groups (P = .94). The LIA group demonstrated a trend toward lower pain scores at 24 hours postoperatively (P = .10). Opioid consumption during the first 24 hours following surgery was significantly reduced in the LIA group compared with the PNB group (P < .0001). There was a trend toward fewer postoperative nerve and cardiopulmonary complications in the LIA group than the PNB group (P = .22 and P = .40, respectively) Conclusion Periarticular local injection mixtures provide comparable pain control to regional nerve blocks while reducing opioid use and postoperative complications following TSA. Local injection of a multimodal anesthetic solution is a viable option for pain management in TSA.

Abstract
INTRODUCTION Regional anaesthesia (RA) is often used in shoulder surgery because it provides adequate postoperative analgesia and may enhance the patient outcome. RA reduces overall opioid consumption and is frequently used in enhanced recovery programs to decrease hospital stay. However, there is very limited literature confirming these advantages in the surgical repair of proximal humerus fractures. This paper reviews the current literature on the use of RA in pain management after surgical repair of these fractures and evaluates the effect of RA on the functional outcome, length of stay in hospital, and health care expenditure. MATERIALS AND METHODS The PubMed, Embase, Web of Science, and Cochrane Library databases were searched up to March 1, 2018. Studies investigating the use of RA in the management of proximal humerus fractures were included. RESULTS Eleven studies (containing 1872 patients) were eligible for inclusion. The analgesic effect of RA was investigated in eight studies that confirmed its pain-relieving ability. Two studies measured functionality and length of hospitalization and suggested that RA improved function and shortened the stay in hospital. Nine papers mentioned side effects associated with RA while three articles claim that RA decreases the incidence of adverse events associated with general anaesthesia. CONCLUSIONS This systematic review suggests that RA is a good option for postoperative analgesia in patients undergoing surgical repair of a proximal humerus fracture and is associated with fewer adverse events, a shorter recovery time, and a better functional outcome than those achieved by general anaesthesia alone. However, given the limited amount of data available, conclusions need to be made with caution and prospective studies are needed in the future.

Abstract
Peripheral nerve blockade is gaining popularity as an analgesic option for both upper or lower limb surgery. Published evidence supports the improved efficacy of regional techniques when compared to conventional opioid analgesia. The incidence of neurological deficit after surgery associated with peripheral nerve block is unclear. This paper reports on neurological outcomes occurring after 1065 consecutive peripheral nerve blocks over a one-year period from a single institution. All patients receiving peripheral nerve blocks for surgery were prospectively followed for up to 12 months to determine the incidence and probable cause of any persistent neurological deficit. Formal independent neurological review and testing was undertaken as indicated. Thirteen patients reported symptoms that warranted further investigation. A variety of probable causes were identified, with peripheral nerve block being implicated in two cases (one resolved at nine months and one remaining persistent). Overall incidence of block-related neuropathy was 0.22%. Persistent postoperative neuropathy is a rare but serious complication of surgery associated with peripheral nerve block. Formal follow-up of all such blocks is recommended to assess causality and allow for early intervention.

Abstract
Introduction: Shoulder arthroscopies are among the most frequently performed surgeries by orthopaedic surgeons. Little is known about complication rates among recently trained surgeons. The purpose of this study was to examine the type and frequency of complications of common arthroscopic shoulder procedures performed by candidates challenging the American Board of Orthopaedic Surgery: Part II, certification examination. Methods: Data were obtained from the American Board of Orthopaedic Surgery database for orthopaedic surgeons who sat for the part II examination from 2012 to 2016. In total, 27,072 procedures were reviewed. The database was queried to determine the type and frequency of complications for patients who underwent shoulder arthroscopy, including arthroscopic rotator cuff repair, labrum repair, biceps tenodesis, and bony/soft tissue débridement procedures. Complications were classified as surgical, anesthetic, or medical. Factors affecting complication rates were investigated including surgeon's fellowship training, geographic location, and patients’ age and sex. Results: Patients with surgical complications (n = 2,133; 7.9%) were more common than anesthetic (n = 263; 1.0%) or medical (n = 607; 2.2%) complications. There was a significant variation in the surgical complication rate among different arthroscopic shoulder procedures, ranging from 5.4% for labral repair to 10.3% for rotator cuff repair and biceps tenodesis. Stiffness/arthrofibrosis was the most commonly recorded surgical complication (2.2%). Surgical complication rates were lowest in the Northeast region (6.7%; P < 0.01) and in patients younger than 21 years (3.8%; P < 0.01). Women had significantly higher rate of complications than men (8.4% versus 7.6%; P = 0.02). Among anesthetic-related complications, 61.6% were related to regional nerve blocks. The overall revision surgery and readmission rates were 0.8% and 1.0%, respectively. Conclusion: The overall self-reported surgical complication rate for arthroscopic shoulder procedures was 7.9%, which is higher than the rates reported in the literature. Although the rate of anesthetic complications is low (1.0%), adverse events related to nerve blocks made up most of the overall anesthetic related complications.

Abstract
Introduction Interscalene regional anesthesia is effective for pain management but is not without complications. To determine whether postoperative neurologic findings were related to the surgery versus the regional catheter, we developed the dry catheter technique where patients could be examined after the surgery prior to dosing the catheter. The purpose of the study was to assess the utility of the dry catheter block in recognizing neurological deficits associated with regional anesthesia. Methods An interscalene catheter was placed but not started. After the surgery, a neurovascular examination was performed. If the examination was normal, the regional anesthesia was started. Throughout the patient’s hospitalization, pain levels were collected. Results A total of 125 shoulders were studied. There were 9 postoperative nerve-related complications. The patients experienced the most pain relief in the first 12 hours. Conclusion The dry catheter technique allows differentiation between complications associated with regional anesthesia versus those associated with the surgery. Although interscalene anesthesia provided effective pain control, we stopped using it because we felt its complication rate was too high.

Abstract
The purpose of this review was to determine the incidence and duration of peripheral neurologic symptoms following interscalene blocks for shoulder surgery. Three databases were reviewed for subjective and objective injuries by guidance modality and delivery method. The incidence of neurologic injuries following single site injection interscalene blocks, 3.16%, was significantly less than the 5.24% incidence for continuous catheter infusion interscalene blocks. Less than 0.51% of peripheral neurologic symptoms persisted beyond 1 year for both groups. There is a notable risk of injury following interscalene blocks by all modes of guidance and anesthetic technique, but only a small percentage of injuries persist.

Abstract
Postoperative pain control is a significant concern after total shoulder arthroplasty. Injectable periarticular liposomal bupivacaine, which has been found to decrease opioid use after orthopedic procedures, has been proposed as a viable alternative to regional anesthesia. This study compared the efficacy of liposomal bupivacaine vs interscalene block among patients undergoing total shoulder arthroplasty. A retrospective review was conducted of 79 patients who underwent anatomic total shoulder arthroplasty performed by a single surgeon between January 2013 and April 2015. Patient demographics, in-hospital Numeric Pain Rating Scale (NPRS) score obtained at 12-hour intervals, length of stay, and total in-hospital morphine equivalents in both the bupivacaine (n=25) and block (n=44) groups were recorded. Differences in length of stay, morphine equivalents, and age were assessed with Wilcoxon tests. Sex differences were assessed with the chi-square test. Repeated measures analysis with least square means was used to assess longitudinal changes in NPRS scores. No significant differences were found between groups for sex (P=.89), age (P=.81), American Society of Anesthesiologists classification (P=.50), preoperative opioid use (P=.41), length of stay (P=.32), or morphine equivalents (P=.71). The average NPRS score in the first 12 hours was 3.01 for the bupivacaine group and 4.41 for the interscalene block group (P=.25). By 48 hours postoperatively, average NPRS scores were similar (P=.93) for the 2 groups, 4.90 for the bupivacaine group and 4.19 for the interscalene block group. The findings for this cohort of patients undergoing anatomic total shoulder arthroplasty showed no significant difference for pain scores, postoperative narcotic use, or length of stay with injectable liposomal bupivacaine vs interscalene block.

Abstract
BACKGROUND Effective postoperative pain management after shoulder arthroscopy is a critical component to recovery, rehabilitation, and patient satisfaction. PURPOSE This systematic review provides a comprehensive overview of level 1 and level 2 evidence regarding postoperative pain management for outpatient arthroscopic shoulder surgery. STUDY DESIGN Systematic review. METHODS We performed a systematic review of the various modalities reported in the literature for postoperative pain control after outpatient shoulder arthroscopy and analyzed their outcomes. Analgesic regimens reviewed include regional nerve blocks/infusions, subacromial/intra-articular injections or infusions, cryotherapy, and oral medications. Only randomized control trials with level 1 or level 2 evidence that compared 2 or more pain management modalities or placebo were included. We excluded studies without objective measures to quantify postoperative pain within the first postoperative month, subjective pain scale measurements, or narcotic consumption as outcome measures. RESULTS A combined total of 40 randomized control trials met our inclusion criteria. Of the 40 included studies, 15 examined nerve blocks, 4 studied oral medication regimens, 12 studied subacromial infusion, 8 compared multiple modalities, and 1 evaluated cryotherapy. Interscalene nerve blocks (ISBs) were found to be the most effective method to control postoperative pain after shoulder arthroscopy. Increasing concentrations, continuous infusions, and patient-controlled methods can be effective for more aggressively controlling pain. Dexamethasone, clonidine, intrabursal oxycodone, and magnesium have all been shown to successfully improve the duration and adequacy of ISBs when used as adjuvants. Oral pregabalin and etoricoxib administered preoperatively have evidence supporting decreased postoperative pain and increased patient satisfaction. CONCLUSION On the basis of the evidence in this review, we recommend the use of ISBs as the most effective analgesic for outpatient arthroscopic shoulder surgery.

Anterior Interosseous Nerve Neuropraxia Secondary to Shoulder Arthroscopy and Open Subpectoral Long Head Biceps Tenodesis. Case Rep Orthop 2017; 2017:7252953.

Abstract
Arthroscopic rotator cuff tendon repair is a common elective procedure performed by trained orthopaedic surgeons with a relatively low complication rate. Specifically, isolated neuropraxia of the anterior interosseous nerve (AIN) is a very rare complication of shoulder arthroscopy. An analysis of peer-reviewed published literature revealed only three articles reporting a total of seven cases that describe this specific complication following standard shoulder arthroscopic procedures. This article reports on three patients diagnosed with AIN neuropraxia following routine shoulder arthroscopy done by a single surgeon within a three-year period. All three patients also underwent open biceps tenodesis immediately following completion of the arthroscopic procedures. The exact causal mechanism of AIN neuropraxia following shoulder arthroscopy with biceps tenodesis is not known. This case report reviews possible mechanisms with emphasis on specific factors that make a traction injury the most likely etiology in these cases. We critically analyze our operating room setup and patient positioning practices in light of the existing biomechanical and cadaveric research to propose changes to our standard practices that may help to reduce the incidence of this specific postoperative complication in patients undergoing elective shoulder arthroscopy with biceps tenodesis.

Abstract
PURPOSE The goal of the study was to evaluate the efficacy of additional axillary nerve block (ANB) with suprascapular nerve block (SSNB) and patient-controlled anaesthesia (PCA) with no device assistance after arthroscopic rotator cuff repair. The hypothesis is that patients with intravenous (IV) PCA and the blockade of the two main nerves (SSNB + ANB) experienced lesser pain than patients with IV PCA or IV PCA + SSNB. METHODS The 114 patients undergoing arthroscopic rotator cuff repair were allocated randomly to three groups as follows: group I, intravenous PCA pumps (only PCA); group II, IV PCA + SSNB using a blind technique (PCA + SSNB); and group III, IV PCA + SSNB + ANB using a blind technique (PCA + SSNB + ANB). Pain visual analogue scale (VAS) scores were evaluated at 1, 6, 12, 24, 36, and 48 post-operative hours. Furthermore, the degree of pain was compared according to cuff tear size. RESULTS The pain VAS score of group III was lower than that of the other two groups and was significantly lower at post-operative hours 1, 6, and 12. In addition, the larger cuff tear tended to be indicative of greater pain. However, all groups experienced rebound pain. CONCLUSION PCA + SSNB + ANB using a blind technique is a better pain control method than PCA + SSNB and only PCA during the initial 12 post-operative hours. PCA + SSNB + ANB is a cost-effective, time-saving, and easily performed method for post-operative pain control as an axis of multimodal pain control strategy. LEVEL OF EVIDENCE II.

Abstract
HYPOTHESIS Our hypothesis was that in patients undergoing shoulder arthroplasty, a prospective randomized trial would find no significant differences in average daily pain scores of those treated with interscalene nerve block (INB) vs. local liposomal bupivacaine (LB). METHODS Sixty patients undergoing primary shoulder arthroplasty were assessed for eligibility. Study arms included either intraoperative local infiltration of LB (20 mL bupivacaine/20 mL saline) or preoperative INB, with a primary outcome of postoperative average daily visual analog scale scores for 4 days. Secondary outcomes assessed included opioid consumption, length of stay, and complications. Randomization was by a computerized algorithm. Only the observer was blinded to the intervention. RESULTS Three patients were excluded, all before randomization. A total of 57 patients were analyzed. Outcomes showed a significant increase in pain in the LB group between 0 and 8 hours postoperatively (mean [standard deviation] 5.3 [2.2] vs. 2.5 [3.0]; P = .001). A significant increase in intravenous morphine equivalents was found in the INB group at 13 to 16 hours (mean [standard deviation] 1.2 [0.9] vs. 0.6 [0.7]; P = .01). No significant differences were found in any variable after postoperative day 0 between the 2 groups. CONCLUSION An increase in early postoperative pain on the day of surgery was found with LB, whereas the INB group required more narcotics at the end of the day. After the day of surgery, there were no significant differences found in any variables. These findings suggest that LB provides similar overall pain relief as INB, with no increase in complications or length of stay and a decrease in narcotic requirements on the day of surgery.

Effect of preemptive intra-articular morphine and ketamine on pain after arthroscopic rotator cuff repair: a prospective, double-blind, randomized controlled study. Arch Orthop Trauma Surg 2016; 136:233-9. [PMID: 26476719 DOI: 10.1007/s00402-015-2346-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND Rotator cuff tear is a leading etiology of shoulder pain and disability. Surgical treatment is indicated in patients with persistent pain who fail a trial of non-surgical treatment. Pain reduction following rotator cuff repair, particularly within the first 24-48 h, is a major concern to both doctors and patients. This study aimed to compare the postoperative antinociceptive additive effects of pre-incisional intra-articular (IA) ketamine when combined with morphine with two times the dose of morphine or saline. METHODS In this prospective, randomized, double blind, controlled trial patients undergoing arthroscopic rotator cuff tear repair (ARCR) under general anesthesia were enrolled. Patients were randomly assigned to one of the three intervention groups. Twenty minutes prior to incision, morphine (20 mg/10 ml), ketamine (50 mg + morphine 10 mg/10 ml), or saline (0.9 % 10 ml) (n = 15/group), were administered to all patients. First 24 h postoperative analgesia consisted of intravenous patient controlled analgesia (IV-PCA) morphine and oral rescue paracetamol 1000 mg or oxycodone 5 mg. 24-h, 2-week and 3-month patient rated pain numeric rating scale (NRS) and analgesics consumption were documented. RESULTS Patients' demographic and perioperative data were similar among all groups. The 24-h and the 2-week NRSs were significantly (p < 0.05) lower in both treatment groups compared to placebo, but were not significantly different between the two intervention groups. PCA-morphine and oral analgesics were consumed similarly among the groups throughout the study phases. CONCLUSIONS Pre-incisional intra-articular morphine reduced pain in the first 2 weeks after arthroscopic rotator cuff repair. Further research is warranted to elucidate the optimal timing and dosing of IA ketamine and morphine for postoperative analgesic effects.

Abstract
Objectives. Shoulder surgery can produce severe postoperative pain and movement limitations. Evidence has shown that regional nerve block is an effective management for postoperative shoulder pain. The purpose of this study was to investigate the postoperative analgesic effect of intravenous patient-controlled analgesia (PCA) combined with interscalene nerve block in comparison to PCA alone after shoulder surgery. Methods. In this study, 103 patients receiving PCA combined with interscalene nerve block (PCAIB) and 48 patients receiving PCA alone after shoulder surgery were included. Patients' characteristics, preoperative shoulder score and range of motion, surgical and anesthetic condition in addition to visual analog scale (VAS) pain score, postoperative PCA consumption, and adverse outcomes were evaluated. Results. The results showed that PCA combined with interscalene nerve block (PCAIB) group required less volume of analgesics than PCA alone group in 24 hours (57.76 ± 23.29 mL versus 87.29 ± 33.73 mL, p < 0.001) and 48 hours (114.86 ± 40.97 mL versus 183.63 ± 44.83 mL, p < 0.001) postoperatively. The incidence of dizziness in PCAIB group was significantly lower than PCA group (resp., 1.9% and 14.6%, p = 0.005). VAS, nausea, and vomiting were less in group PCAIB, but in the absence of significant statistical correlation. Conclusion. Interscalene nerve block is effective postoperatively in reducing the demand for PCA analgesics and decreasing opioids-induced adverse events following shoulder surgery.

Abstract
Shoulder arthroscopic procedures have become common in today's orthopedic practice. The safety of shoulder arthroscopy though well established, is not without complications both minor and significant. The true incidence of complications is difficult to identify in the current literature. However, as with all procedures, complications associated with shoulder arthroscopy do occur. General complications (ie, infection), those specific to shoulder arthroscopy (ie, positioning) and those associated with specific procedures (ie, failure) all have been recognized. The purpose of this article is to review the current literature regarding complications in shoulder arthroscopy, provide insight into the risk factors and types of complications and to provide guidelines on the prevention and management of complications if and when they occur.

Abstract
BACKGROUND Interscalene nerve blocks (ISBs) have been shown to be an effective option for regional anesthesia in shoulder surgery. Our study presents survey results of shoulder surgeons' perceptions of ISBs and a literature summary of complications rates with ISB use. METHODS A survey addressing demographics, preferences, treatment patterns, risks/benefits, and patient recommendations regarding the use of ISBs was created. Respondents were also asked whether they would elect an ISB if personally undergoing shoulder surgery, and results of other questions were stratified based on this personal preference. The survey was administered electronically to all members of the American Shoulder and Elbow Surgeons. A literature review of ISB-related complication rates was compiled from 13 studies of shoulder surgery using ISB. RESULTS Of all respondents, 58.7% would elect a single-shot ISB, 15.0% would elect a continuous catheter, and 26.3% would not elect the use of an ISB if undergoing shoulder surgery. Respondents from a university hospital were 1.44 times more likely to elect any ISB than respondents from a non-university hospital. Improved post-operative pain control was considered the greatest benefit, whereas persistent neuropathy was considered the greatest risk of ISB use. Of the respondents, 76.1% would recommend use of ISB to their patients undergoing shoulder surgery. Our literature review yielded 13 applicable studies that utilized a total of 6243 ISBs, with data resulting in a 0.35% major complication rate and an 11.32% minor complication rate in patients. CONCLUSION The majority of shoulder surgeons surveyed in our study would elect to have a single-shot interscalene nerve block if undergoing shoulder surgery themselves, indicating that ISB use is considered a safe and effective anesthetic option among shoulder surgeon specialists.

Abstract
Necrotizing fasciitis is an aggressive, invasive soft tissue infection. Because it can rapidly progress to patient instability, prompt diagnosis followed by urgent debridement is critical to decreasing mortality. Despite the importance of early diagnosis, necrotizing fasciitis remains a clinical diagnosis, with little evidence in the literature regarding the effectiveness of diagnostic tools or criteria. Common clinical findings are nonspecific, including pain, blistering, crepitus, and swelling with or without fever and a known infection source.This article describes a patient who was transferred to the authors' institution from another hospital, where she had been taken following seizure activity and was treated with antibiotics for suspected cellulitis at the intravenous catheter placement site on her left dorsal hand. On admission to the current authors' institution, she presented with pain and swelling in the setting of significant left upper-extremity emphysema. She had undergone a left shoulder arthroscopy 4 weeks previously. Vital signs were within normal limits, and a preoperative chest radiograph was read as normal. The patient underwent an emergent fasciotomy, irrigation and debridement of the left upper extremity, and intravenous antibiotics for suspected necrotizing fasciitis. Intraoperative findings indicative of infection were absent, and a left apical pneumothorax was later found on postoperative chest imaging.In a stable patient with a normal chest radiograph on presentation who demonstrates upper-extremity crepitus suspicious for necrotizing fasciitis, a chest computed tomography scan may be indicated to rule out an intrathoracic source.

Abstract
BACKGROUND The goal of this study was to compare 2 consecutive series of 240 reverse total shoulder arthroplasties (TSA) in order to evaluate if the increase in surgeon experience modified the indications, clinical and radiographic results, and rate of complications. MATERIAL AND METHODS Two hundred forty reverse TSA performed between July 2003 and March 2007 were clinically and radiographically evaluated by an independent examiner with a minimum follow-up of 2 years and compared with a previous published study (240 cases implanted by the same 2 surgeons between May 1995 and June 2003). RESULTS The main etiology remained cuff tear arthropathy with an increase noted between the 2 studies. The rate of revision arthroplasty as an etiology decreased from 22.5% to 9.1%. Conversely, the rate of rheumatoid arthritis increased from 0.4% to 6.3%. The average postoperative Constant score was significantly better than the first series (66.9 vs 59.7, P < .001). The postoperative complication rate decreased with increased experience (from 19% to 10.8%), with dislocations reducing (from 7% to 3.2%), and infections reducing (from 4% to 0.9%). However, the number of nerve palsies increased. The revision rate decreased from 7.5% to 5%. The rate of glenoid notching remained stable, but the severity of notching decreased. CONCLUSION Experience did not lead us to operate on younger patients, but significantly modified patient selection, results, and complications. Increased experience with the reverse shoulder arthroplasty did not reduce the rate of glenoid notching.

Abstract
Background: Interscalene brachial plexus block (ISBPB) is an effective technique for shoulder surgery and postoperative pain control. The aim of this study is to compare the analgesic efficacy of 0.1% vs 0.2% bupivacaine for continuous postoperative pain control following arthroscopic shoulder surgery. Methods: A total of 40 adult patients divided into two groups (each 20 patients) undergoing arthroscopic shoulder surgery were randomized to receive an ultrasound-guided ISBPB of either 0.1% or 0.2% bupivacaine 10 ml bolus plus 5 ml/h infusion through interscalene catheter. Standard general anesthesia was given. Both groups received rescue postoperative PCA morphine. Pain, sensory, and motor power were assessed before for all patients, 20 minute after the block, postoperatively in the recovery room, and at 2, 6, 12, and 24 hours thereafter. The patient and surgeon satisfaction and the analgesic consumption of morphine were recorded in the first 24 hours postoperatively. A nonparametric Mann-Whitney was used to compare between the two groups for numerical rating scale, morphine consumption in different time interval. Results: Group 1 (0.1% bupivacaine) patients had significantly received more intraoperative fentanyl and postoperative morphine with higher pain scores at 24 hours postoperatively vs group 2 (0.2% bupivacaine) patients. Conclusions: The use of ultrasound-guided ISBPB with 0.2% bupivacaine provided better intra- and post-operative pain relief vs 0.1% bupivacaine in arthroscopic shoulder surgery.

Abstract
The lateral decubitus and beach-chair positions each offer unique benefits to the shoulder surgeon with respect to visualization, efficiency, and ease during arthroscopic shoulder procedures. The purpose of this article was to comprehensively review the reports and studies documenting independent and dependent complications related to patient positioning and anesthesia during arthroscopic shoulder surgery. The lateral decubitus position has been associated with the potential for peripheral neurapraxia, brachial plexopathy, direct nerve injury, and airway compromise. The beach-chair position has been associated with cervical neurapraxia, pneumothorax, and the potential for end-organ hypoperfusion injuries (when deliberate hypotension is used). Potentially concerning are hypotensive bradycardic events, which may be relatively common in association with the use of epinephrine-containing interscalene anesthetics in beach chair-positioned patients. Irrigant complications (fluid spread, ventricular tachycardia) are avoidable risks not unique to either specific position. Although minor transient anesthetic- and position-related complications (neurapraxia, hypotension) may occur in as many 10% to 30% of patients, major complications such as end-organ damage or permanent impairments are exceedingly rare. Regardless of position, complications are almost uniformly avoidable if surgeon and anesthetist exercise care and prudent attention to position and anesthetic choices. The purpose of this article is to review the potential for position- and anesthesia-related complications and acquaint the shoulder surgeon with the proposed pathophysiologic mechanisms that can lead to them.

Abstract
This report describes a patient who had a series of daily interscalene nerve blocks to treat pain following a shoulder manipulation for postsurgical stiffness. She experienced acute respiratory compromise that persisted for many weeks. All typical and unusual causes of these symptoms were ruled out. Her treating pulmonologist theorized that the ipsilateral carotid body had been injured. However, it was subsequently determined that the constellation of symptoms and their prolonged duration were best explained by a poor stress response from Addison's disease coupled with exacerbation of early onset myasthenia gravis. This patient's case is not a typical reaction to interscalene nerve blocks, and thus preoperative testing would not be recommended for myasthenia gravis or Addison's disease without underlying suspicion. We describe this report to inform physicians to consider a workup for these diagnoses if a typical workup rules out all usual causes of complications from an interscalene block.

Abstract
Regional anesthesia and analgesia have been associated with improved analgesia, decreased postoperative nausea and vomiting, and increased patient satisfaction for many types of surgical procedures. In obstetric anesthesia care, it has also been associated with improved maternal mortality and major morbidity. The majority of neurological adverse events following regional anesthesia administration result in temporary sensory symptoms; long-term or permanent disabling motor and sensory problems are very rare. Infection and hemorrhagic complications, particularly with neuraxial blocks, can cause neurological adverse events. More commonly, however, there are no associated secondary factors and some combination of needle trauma, intraneural injection, and/or local anesthetic toxicity may be associated, but their individual contributions to any event are difficult to define.

Abstract
Shoulder arthroscopy is generally a safe and effective method for treating a wide variety of shoulder pathology. Fortunately, complications following shoulder arthroscopy are rare, with reported rates between 4.6% and 10.6%.¹⁻⁷ These rates may be underestimated, as underreporting of complications and varying definitions of the term complication are likely. During shoulder arthroscopy, complications may occur at numerous points. The surgeon must be aware of potential problems and take necessary measures to prevent them. This article describes common complications after arthroscopic shoulder surgery. Although failure of treatment and postoperative stiffness are undesirable outcomes, they are not described.

Abstract
OBJECTIVE To evaluate the efficacy of suprascapular nerve block in combination with infusion of anesthetic into the subacromial space, compared with interscalene block. METHODS Forty-five patients with small or medium-sized isolated supraspinatus tendon lesions who underwent arthroscopic repair were prospectively and comparatively evaluated through random assignation to three groups of 15, each with a different combination of anesthetic methods. The efficacy of postoperative analgesia was measured using the visual analogue scale for pain and the analgesic, anti-inflammatory and opioid drug consumption. Inhalation anesthetic consumption during surgery was also compared between the groups. RESULTS The statistical analysis did not find any statistically significant differences among the groups regarding anesthetic consumption during surgery or postoperative analgesic efficacy during the first 48 hours. CONCLUSION Suprascapular nerve block with infusion of anesthetic into the subacromial space is an excellent alternative to interscalene block, particularly in hospitals in which an electrical nerve stimulating device is unavailable.

Abstract
INTRODUCTION Interscalene brachial plexus block (ISB) is widely used as an adjuvant regional pain therapy in patients undergoing major shoulder surgery and has proved its effectiveness on postoperative pain reduction and opioid-sparing effect. METHOD This single-center, prospective, double-blind, randomized and placebo-controlled study was to compare the effectiveness of a single-shot and a patient-controlled catheter insertion ISB system after major open-shoulder surgeries. Seventy patients were entered to receive an ISB and a patient-controlled interscalene catheter. The catheter was inserted under ultrasound guidance. Patients were then assigned to receive one of two different postoperative infusions, either 0.2% ropivacaine (catheter group) or normal saline solution (single-shot group) via a disposable patient-controlled infusion pump. RESULTS The study variables were amount of rescue medication, pain at rest and during physiotherapy, patient satisfaction and incidence of unwanted side effects. The ropivacaine group revealed significantly less consumption of rescue medication within the first 24 h after surgery. Incidence of side effects did not differ between the two groups. CONCLUSION Based on our results, we recommend the use of interscalene plexus block in combination with a patient-controlled catheter system under ultrasound guidance only for the first 24 h after major open-shoulder surgery.

Abstract
The suprascapular nerve is responsible for most of the sensory innervation to the shoulder joint and is potentially at risk during surgery. In this study, 31 shoulders in 22 cadavers were dissected to investigate the sensory innervation of the shoulder joint by the suprascapular nerve, with special reference to its sensory branches. In 27 shoulders (87.1%), a small sensory branch was observed that splits off from the main stem of the suprascapular nerve proximal (48.2%), inferior (40.7%), or distal (11.1%) to the transverse scapular ligament. This percentage is considerably higher than has been previously found. In 74.2% of the shoulders, an acromial branch was also found, originating just proximal to the scapular neck, running to the infraspinatus tendon. These cadaveric results indicate that sensory branches to the shoulder joint are more common and numerous than previously described and therefore should be considered in shoulder surgery and nerve blocks to this area.

Abstract
PURPOSE This study was performed to evaluate the efficacy of interscalene regional blocks and infusion pumps for postoperative pain control after arthroscopic subacromial decompression with or without arthroscopic rotator cuff repair. METHODS Seventy-six patients were included in the prospective study. Participants were randomized into 4 treatment groups: (1) interscalene regional block, (2) infusion pump with 0.5% bupivacaine, (3) interscalene block combined with an infusion pump containing 0.5% bupivacaine, and (4) interscalene block combined with an infusion pump containing 0.9% saline solution. The interscalene regional block was performed with a nerve stimulator. Infusion pump catheters were positioned in the subacromial space. Visual analog scale (VAS) data were collected preoperatively, at 1 and 2 hours postoperatively, and daily for an additional 6 days postoperatively. An analysis of variance with a Student-Newman-Keuls post hoc test was used to identify statistically significant (P < .05) differences in VAS scores between the groups at each time point. Percentages of patients who took medication for pain management in the recovery room were compared between the 4 groups by use of chi(2) analysis. RESULTS Significant differences were noted in VAS scores postoperatively. Group 2 (pump only) had significantly higher scores than all other groups for the first 2 hours. Furthermore, group 4 (block and pump filled with saline solution) had significantly lower VAS scores than group 1 (block only) at 1 hour. This difference was no longer significant by the second hour. The percentage of patients who required oral narcotics or intravenous pain medication was significantly larger for group 2 than for the other groups. CONCLUSIONS The interscalene regional block provided more pain relief than infusion pumps immediately after arthroscopic shoulder surgery. Infusion pumps did not significantly reduce pain levels after the blocks wore off. LEVEL OF EVIDENCE Level II, prospective comparative therapeutic study.

Abstract
INTRODUCTION The use of extended local anaesthesia for postoperative pain has previously been reported, and has several advantages over other methods, including ease of placement, safety, reliability, lower cost and effective analgesia. We present our experience with a portable elastomeric infusion device in patients undergoing arthroscopic subacromial decompression, and make a case for its potential to allow same-day discharge. PATIENTS AND METHODS Forty patients undergoing arthroscopic subacromial decompression were followed-up. At the end of the procedure, an epidural catheter connected to a portable elastomeric local anaesthetic infusion system was inserted into the subacromial space. All patients were electively admitted for overnight stay postoperatively and assessed using a visual analogue scale (VAS) to evaluate their level of pain. RESULTS No patient reported severe pain at any stage. None of the patients required any parenteral opiate analgesia with the pump in situ. CONCLUSIONS These findings suggest that the use of this elastomeric infusion device following shoulder surgery allows safe and early discharge of patients with decreased need for parenteral opiate analgesia.

Abstract
Interscalene brachial plexus block is a commonly used anesthetic. However, substantial complications can be associated with its use. Our study included 15 years of data from a local medical center and 3 decades of records from the national American Society of Anesthesiology Closed Claims Project. The hospital had 27 peripheral neurologic injuries, 3 central nervous system complications, 6 respiratory complications, and 5 cardiovascular complications. Of these complications, 14 were still present at the most recent follow-up, some causing major compromise of the patient's comfort and function. All central blocks, local toxicities, and respiratory complications resolved. In the hospital series, more experienced anesthesiologists tended to have lower complication rates. The American Society of Anesthesiology Closed Claims database had 20 peripheral neurologic injuries, 10 respiratory complications, 5 central nervous system complications, 4 deaths, 2 emotional disturbances, and 1 other unknown event. Of the complications, 19 were described as permanent. Interscalene brachial plexus block can be accompanied by substantial and disabling complications, especially when administered by less experienced anesthesiologists.

Abstract
BACKGROUND Regional anesthesia (RA) provides excellent anesthesia and analgesia for many surgical procedures. Anesthesiologists and patients must understand the risks in addition to the benefits of RA to make an informed choice of anesthetic technique. Many studies that have investigated neurological complications after RA are dated, and do not reflect the increasing indications and applications of RA nor the advances in training and techniques. In this brief narrative review we collate the contemporary investigations of neurological complications after the most common RA techniques. METHODS We reviewed all 32 studies published between January 1, 1995 and December 31, 2005 where the primary intent was to investigate neurological complications of RA. RESULTS The sample size of the studies that investigated neurological complications after central and peripheral (PNB) nerve blockade ranged from 4185 to 1,260,000 and 20 to 10,309 blocks, respectively. The rate of neuropathy after spinal and epidural anesthesia was 3.78:10,000 (95% CI: 1.06-13.50:10,000) and 2.19:10,000 (95% CI: 0.88-5.44:10,000), respectively. For common PNB techniques, the rate of neuropathy after interscalene brachial plexus block, axillary brachial plexus block, and femoral nerve block was 2.84:100 (95% CI 1.33-5.98:100), 1.48:100 (95% CI: 0.52-4.11:100), and 0.34:100 (95% CI: 0.04-2.81:100), respectively. The rate of permanent neurological injury after spinal and epidural anesthesia ranged from 0-4.2:10,000 and 0-7.6:10,000, respectively. Only one case of permanent neuropathy was reported among 16 studies of neurological complications after PNB. CONCLUSIONS Our review suggests that the rate of neurological complications after central nerve blockade is <4:10,000, or 0.04%. The rate of neuropathy after PNB is <3:100, or 3%. However, permanent neurological injury after RA is rare in contemporary anesthetic practice.

Abstract
PURPOSE Recent public opinion has focused on the lay perception that postoperative pain control is inadequate. The Joint Commission on Accreditation of Healthcare Organizations has attempted to address this issue by mandating patient-reported numeric pain scores as part of postoperative pain assessment. No studies exist to validate these scores in orthopaedics. The purpose of this study was 3-fold: (1) to determine which preoperative variables were associated with elevated postoperative pain scores, (2) to identify whether pain scores correlated with more traditional signs and symptoms of pain, and (3) to identify whether patients with a high pain score (HPS) affect perioperative and postoperative complication rates. METHODS We retrospectively evaluated 105 patients who underwent routine arthroscopic rotator cuff repair over a 12-month period. Correlations and linear regression analysis were used to assess factors associated with postoperative pain scores. Logistic regression analysis was used to construct a model of preoperative, demographic, surgical, and postoperative variables associated with HPSs. RESULTS Wide variability existed in pain scores despite the similarity of the surgical stimulus. What subtle differences that were present in the surgical procedures had no bearing on pain scores. No correlation existed between pain scores and any physiologic correlate of pain. Pain scores were correlated with Workers' Compensation insurance, preoperative antianxiety medications, antidepressant medications, preoperative narcotics, and alcohol use. HPS patients had a longer recovery room stay (P < .05) and a higher incidence of postoperative nausea than those with a normal pain tolerance. HPS patients also had a significantly delayed return to work, as well as significantly lower Simple Shoulder Test scores at 6 weeks, although the final shoulder scores were similar to those in patients with a normal pain tolerance. CONCLUSIONS Patient-reported pain scores have been mandated, but they vary widely among patients undergoing virtually the same procedure and correlate poorly with physiologic manifestations of pain. Pain scores tend to correlate with other types of variables, most of which would be expected by the experienced surgeon. The exclusive use of pain scores in postoperative pain management should be limited to prevent complications. LEVEL OF EVIDENCE Level IV, prognostic case series.

Abstract
BACKGROUND Shoulder arthroplasty procedures are seldom performed on an ambulatory basis. Our objective was to examine postoperative analgesia, nausea and vomiting, patient satisfaction and complications of ambulatory shoulder arthroplasty performed using interscalene brachial plexus block (ISB). MATERIALS AND METHODS We prospectively examined 82 consecutive patients undergoing total and hemi-shoulder arthroplasty under ISB. Eighty-nine per cent (n=73) of patients received a continuous ISB; 11% (n=9) received a single-injection ISB. The blocks were performed using a nerve stimulator technique. Thirty to 40 mL of 0.5% ropivacaine with 1:400,000 epinephrine was injected perineurally after appropriate muscle twitches were elicited at a current of less than 0.5% mA. Data were collected in the preoperative holding area, intraoperatively and postoperatively including the postanesthesia care unit (PACU), at 24h and at seven days. RESULTS Mean postoperative pain scores at rest were 0.8 ± 2.3 in PACU (with movement, 0.9 ± 2.5), 2.5 ± 3.1 at 24h and 2.8 ± 2.1 at seven days. Mean postoperative nausea and vomiting (PONV) scores were 0.2 ± 1.2 in the PACU and 0.4 ± 1.4 at 24h. Satisfaction scores were 4.8 ± 0.6 and 4.8 ± 0.7, respectively, at 24h and seven days. Minimal complications were noted postoperatively at 30 days. CONCLUSIONS Regional anesthesia offers sufficient analgesia during the hospital stay for shoulder arthroplasty procedures while adhering to high patient comfort and satisfaction, with low complications.

Abstract
There has been resistance to the use of interscalene regional block for arthroscopic shoulder surgery because of concerns about potential complications and failed blocks with the subsequent need for general anesthesia. The purpose of this study was to assess whether interscalene regional block is safe and effective and offers many advantages over general anesthesia for outpatient arthroscopic shoulder surgery. Through a retrospective chart review of consecutive arthroscopic shoulder surgeries over a 2.5-year time period, in a tertiary university medical center with an anesthesiology residency, 277 interscalene blocks (96%) were successful; 12 (4%) required general anesthesia because of an inadequate block. There were no seizures, pneumothoraces, cardiac events, or other major complications. There was a 1% rate of minor complications, all of which were transient sensory neuropathies that resolved within 5 weeks on average. We conclude that interscalene block can provide effective anesthesia for arthroscopic shoulder surgery.

Interscalene block anesthesia at an ambulatory surgery center performing predominantly regional anesthesia: a prospective study of one hundred thirty-three patients undergoing shoulder surgery. J Shoulder Elbow Surg 2006; 15:686-90. [PMID: 16949840 DOI: 10.1016/j.jse.2006.02.001] [Citation(s) in RCA: 34] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2005] [Accepted: 02/08/2006] [Indexed: 02/01/2023]
Abstract
Interscalene block (ISB) of the brachial plexus is frequently used for patients undergoing ambulatory shoulder surgery. We previously reported that the incidence of postoperative complaints (neurapraxia) after an ISB was low (3% at 2 weeks), but objective neurologic assessment was not included in the study. The present study combines subjective findings with both preoperative and postoperative objective sensory and motor assessments after an ISB. We prospectively evaluated 133 patients undergoing elective ambulatory shoulder surgery. ISB anesthesia was accomplished by use of 1.5% mepivacaine alone or in combination with bupivacaine (0.5%-0.75%) via a paresthesia technique and a 23-gauge needle. All of the blocks were performed by experienced anesthesiologists. The number of passes with the needle, site of paresthesia, ease of performing the block, and success of the ISB were recorded for each patient. Neurologic assessment was performed preoperatively and up to 2 weeks postoperatively by 1 of 4 health care professionals but not by the anesthesiologists who performed the ISB and included diminished sensation, localized nerve pain, Semmes-Weinstein monofilament pressure threshold sensibility, Weber static 2-point discrimination, and grip strength changes. Patients with postoperative changes were followed up until resolution of symptoms occurred. Successful surgical anesthesia was achieved in 98% of the patients. There was 1 major perioperative complication (0.7%), a seizure that occurred within 5 minutes of the ISB. Two (1.4%) complained of transient postoperative neurapraxias. Neither patient had any changes in objective sensory and motor measurements. Hence, there was no correlation between subjective complaints and objective findings in this study. This study demonstrates that, in the hands of anesthesiologists doing predominantly regional anesthesia, there is a 1.4% incidence of neurologic complications after an ISB. ISB is a safe and effective technique for patients undergoing ambulatory shoulder surgery when an anesthesiologist experienced with regional anesthesia is involved.
