Effects of the costoclavicular block versus interscalene block in patients undergoing arthroscopic shoulder surgery under monitored anesthesia care: a randomized, prospective, non-inferiority study. Korean J Anesthesiol 2023; 76:413-423. [PMID: 36617951 PMCID: PMC10562073 DOI: 10.4097/kja.22638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 01/01/2023] [Accepted: 01/06/2023] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND Recent studies have reported that costoclavicular blocks (CCBs) can consistently block almost all branches of the brachial plexus while sparing the phrenic nerve and provide effective analgesia after shoulder surgery. We aimed to compare the efficacy of the CCB with that of the interscalene block (ISB) as the sole blocking technique for shoulder surgery. METHODS A total of 212 patients undergoing elective arthroscopic shoulder surgery were randomized to receive an ISB or CCB based on a non-inferiority design. All patients received titration sedation with propofol under monitored anesthesia during surgery. The primary outcomes were the proportion of patients with complete motor blockade of the suprascapular nerve (SSN) and incidence of hemidiaphragmatic paralysis (HDP). The secondary outcomes included block-related variables, complications, and postoperative pain scores. RESULTS The proportion of patients with complete motor blockade of the SSN at 20 min between the CCB and ISB groups (53% vs. 66%) exceeded the predefined non-inferiority margin of -5%, but was comparable at 30 min (87% vs. 91%). The CCB resulted in a significantly lower incidence of HDP (7.55% vs. 92.45%), Horner's syndrome (0% vs. 18.87%), and dyspnea (0% vs. 10.38%) than the ISB. None of the patients experienced failed blocks or required conversion to general anesthesia. Pain scores were comparable between the groups. CONCLUSIONS Ultrasound-guided CCBs may be comparable to ISBs, with fewer unfavorable complications in patients with impaired lung function undergoing arthroscopic shoulder surgery.

Abstract
BACKGROUND Peripheral nerve blocks (PNBs) are vital in the administration of surgical analgesia and have grown in popularity for use in lower extremity arthroscopic procedures because of their capacity to safely and effectively control pain. The number and specificity of PNBs, however, have made choosing the best option for a procedure nebulous for orthopaedic surgeons. PURPOSE To present a narrative literature review of the PNBs available for arthroscopic hip and knee procedures that is adapted to an audience of orthopaedic surgeons. STUDY DESIGN Narrative literature review. METHODS A combination of the names of various lower extremity PNBs AND "hip arthroscopy" OR "knee arthroscopy" was used to search the English medical literature including PubMed, Cochrane Library, ScienceDirect, Embase, and Scopus. Placement technique, specificity of blockade, efficacy, and complications were assessed. Searches were performed through May 2, 2021. RESULTS A total of 157 studies were included in this review of lower extremity PNBs. Femoral nerve, lumbar plexus, sciatic nerve, and fascia iliaca compartment blocks were most commonly used in arthroscopic hip surgery, while femoral nerve, 3-in-1, and adductor canal blocks were preferred for arthroscopic knee surgery. Each block demonstrated a significant benefit (P > .05) in ≥1 of the following outcomes: intraoperative morphine, pain scores, nausea, and/or opioid consumption. Combination blocks including the lateral femoral cutaneous nerve block, obturator nerve block, quadratus lumborum block, and L1 and L2 paravertebral block have also been described. Complication rates ranged from 0% to 4.8% in those administered with ultrasound guidance. The most commonly reported complications included muscular weakness, postoperative falls, neuropathy, intravascular and intraneural injections, and hematomas. CONCLUSION When administered properly, PNBs were a safe and effective adjuvant method of pain control with a significant potential to limit postoperative narcotic use. While blockade choice varies by surgeon preference and procedure, all PNBs should be administered with ultrasound guidance, and vigilant protocols for the risk of postoperative falls should be exercised in patients who receive them.

Peripheral Nerve Injury After Upper-Extremity Surgery Performed Under Regional Anesthesia: A Systematic Review. JOURNAL OF HAND SURGERY GLOBAL ONLINE 2022; 4:201-207. [PMID: 35880155 PMCID: PMC9308165 DOI: 10.1016/j.jhsg.2022.04.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 04/25/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose Peripheral nerve injury (PNI) is a known adverse event following upper-limb surgery performed under brachial plexus regional anesthesia (RA). When PNI is noted after surgery, patients and providers often have questions about which factors might have contributed to this complication. This systematic review evaluates the literature on hand and shoulder surgeries performed under ultrasound-guided, plexus RA to identify factors potentially associated with PNI, including the surgery location and block type. We hypothesized that shoulder surgery might be associated with an increased risk of PNI compared to hand surgery. Methods A systematic review of the relevant literature was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Only prospective studies on the use of ultrasound-guided, preoperative, brachial plexus RA for hand or shoulder surgery on adult patients were included. Study groups were categorized according to surgery location and block type and compared across a number of factors via univariate and multivariate analyses. Results A total of 3,037 abstracts were screened; 192 full-text articles were independently reviewed by 2 of the authors; and 53 studies were included in the systematic review analysis. Following hand surgery, PNI was reported at an average rate of 1.35% ± 3.21% across 836 subjects in 40 study groups; after shoulder surgery, the average rate was 0.50% ± 1.57% across 3,383 subjects in 15 study groups. There was no statistically significant correlation between the incidence of PNI and surgery location (P =.70) or any of the most common approaches for brachial plexus anesthesia in the multivariate analysis. Conclusions This systematic review of over 50 articles on upper-limb surgery performed under RA shows no association between the incidence of PNI and the location of surgery or type of brachial plexus block. Type of study/level of evidence Diagnostic II.

Abstract
PURPOSE Serious complications after ultrasound-guided regional anaesthesia can be devastating for the patient. The pathogenesis of postoperative neurological complications (PONC) is multifactorial and includes mechanical, vascular and chemical factors besides the nerve puncture itself. The primary aim of this study was to assess the incidence of PONC after brachial plexus block (BPB). METHODS This is an observational retrospective single-centre study conducted at the regional anaesthesia unit of a teaching hospital. All BPBs performed from January 2011 to November 2019 were included. The outcomes analysed were the incidence, aetiology and diagnosis of PONCs and the incidence of other postoperative complications such as local anaesthetic systemic toxicity (LAST), pneumothorax, wrong-side block, etc. The performance of trainees and experienced anaesthesiologists was compared across all the outcomes. RESULTS From a total of 5340 BPBs included, 15 cases developed PONC, yielding a rate of 2.81:1000 (95% CI 1.70-4.63). Thirteen patients underwent neurophysiological exams which confirmed nine neuropathies. The rate of PONCs for supervised trainees was 1.80:1000 (95% CI 0.701-4.62), not statistically different from that of experienced anaesthesiologists (p = 0.241). Three cases were considered to present with a PONC probably related to BPB [0.562:1,00 (95% CI 0.191-1.65)]. The incidence of long-term PONCs was 1.12:1000 (95% CI 0.515-2.45). Such complications proved irreversible in 2 cases. The incidences of LAST, pneumothorax and other complications observed were 0.749:1000 (95% CI 0.291-1.92), 0.187:1000 (95% CI 0.0331-1.06) and 4.31:1000 (95% CI 2.87-6.46), respectively. CONCLUSIONS This survey suggests that complications after ultrasound-guided BPB, including blocks performed by trainees, are uncommon. TRIAL REGISTRATION Clinicaltrials.gov ID: NCT04451642.

Abstract
The use of anesthetics relieves discomfort in patients during operation, but extensive application of anesthetics can cause damage to the nervous system. Atractylenolide III (ATL-III) is an active ingredient derived from Baizhu, which is a kind of traditional Chinese medicines. Recent studies have shown that ATL-III alleviates inflammation and oxidative stress in various tissues by regulating the PI3K/Akt/mTOR signaling pathway. However, whether or not the application of ATL-III could relieve isoflurane-induced damage in rat hippocampal neurons remains unclear. In this study, rats were stimulated with isoflurane and treated with ATL-III (intragastric administration) simultaneously. After rats were sacrificed, apoptosis and autophagy in the hippocampal neurons were assessed using TUNEL assays and western blotting, respectively. Then, the expression of inflammatory factors was determined by q-PCR and ELISA. The levels of p-PI3K, p-Akt, and p-mTOR were quantified by western blotting. We found that ATL-III relieved isoflurane-induced apoptosis, autophagy and inflammation in hippocampal neurons in rats. ATL-III treatment also inhibited the expression of TNF-α, IL-1β, and IL-6 in these cells. Furthermore, ATL-III promoted the expression of p-PI3K, p-Akt, and p-mTOR in the hippocampal neurons. All these results indicated that ATL-III alleviated isoflurane-induced injury in rat hippocampal neurons by activating the PI3K/Akt/mTOR signaling pathway. PRACTICAL APPLICATIONS: Whether or not Atractylenolide III (ATL-III) could alleviate neurotoxicity induced by anesthetics is unclear. In this study, we investigated the effect of ATL-III on anesthetic-induced nervous system damage. The findings from this study could also provide a novel therapy for the treatment of patients with anesthetic-induced nerve injury.

Abstract
BACKGROUND This study compared the results of regional blocks containing a single anesthetic, bupivacaine, with those containing bupivacaine and 3 additives (buprenorphine, clonidine, and dexamethasone) in patients undergoing foot and ankle surgery. METHODS Eighty patients undergoing foot and ankle surgery over a 9-month period were prospectively enrolled and randomized to receive a peripheral nerve block containing either a single anesthetic (SA) or one with 3 additives (TA). Patients, surgeons, and anesthesiologists were blinded to the groups. Patients maintained pain diaries and were evaluated at 1 and 12 weeks postoperatively. Fifty-six patients completed the study. RESULTS The TA group had a longer duration of analgesic effect than the SA group (average 82 vs 34 hours, P < .05). Forty-eight hours after surgery, 93% of SA blocks, compared with 34% of TA blocks, had completely worn off. The TA group had a longer duration of sensory effects. At 3 months, 10 of 26 (38.5%) TA patients, compared with 3 of 30 (10%) SA patients, reported postoperative neurologic symptoms. Pain scores in both groups were not statistically different at 1 week or 3 months after surgery. Patients in both groups were similarly satisfied with their blocks. CONCLUSION Both types of nerve blocks provided equivalent pain control and patient satisfaction in patients undergoing foot and ankle surgery. The 3-additive agent blocks were associated with a longer duration of pain relief and a longer duration of numbness, as well as higher rates of postoperative neurologic symptoms. Longer pain relief may be obtained at the cost of prolonged sensory deficits. LEVEL OF EVIDENCE Level II, prospective comparative study.
