Abstract
INTRODUCTION Carotid endarterectomy is performed for patients with symptomatic carotid artery occlusions. Surgery can be performed under general and regional anesthesia. Traditionally, surgery is performed under deep cervical plexus block which is technically difficult to perform and can cause serious complications. This case series describes 5 cases in which an intermediate cervical plexus block was used in combination with a superficial cervical plexus block for Carotid endarterectomy surgery. METHODS Five patients who were classified as American Society of Anesthesiologists 2-3 were scheduled for Carotid endarterectomy due to symptoms and more than 70% occlusion of the carotid arteries. The procedures were carried out in the University Teaching Hospital- Peradeniya, Sri Lanka. All patients were given superficial cervical plexus block followed by intermediate cervical plexus block using 2% lignocaine and 0.5% plain bupivacaine. RESULTS Adequate anesthesia was achieved in 4 patients, and local infiltration was necessary in 1 patient. Two patients developed hoarseness of the voice, which settled 2 h after surgery. Hemodynamic fluctuations were observed in all 5 patients. No serious complications were observed. All 5 patients had uneventful recoveries. DISCUSSIONS Regional anesthesia for CEA is preferable in patients who are medically complicated to undergo anesthesia or in patients for whom cerebral monitoring is not available. Intermediate cervical plexus block is described for thyroid surgeries in literature, but not much details on its use for carotid surgeries. Deep cervical plexus blocks has few serious complications which is not there with the use of ICPB making it a good alternative for CEA surgeries . CONCLUSIONS Superficial cervical plexus block and intermediate cervical plexus block can be used effectively for providing anesthesia for patients undergoing Carotid endarterectomy. It is safe and easier to conduct than deep cervical plexus block and enables monitoring of cerebral function.

Abstract
Post-surgical neuropathic pain is still an underdiagnosed medical condition with persistent pain occurring in 10-50% of patients submitted to surgery. We present a case of a 52-year-old patient with persistent paracervical, supraclavicular, and upper chest neuropathic pain after the excision of a massive deep right cervical tumor, concluded to be an accessory spinal nerve schwannoma. A thorough physical and ultrasound examination helped conclude injury of the superficial cervical plexus. Therefore, an ultrasound-guided hydrodissection of several neuromas was performed at the level of the superficial cervical plexus. After three procedures, pain and quality of life scores improved, with a reduction of anxiety and depression symptoms. Due to the positive response, the patient was referred for a peripheral nerve stimulator implantation, allowing self-control of pain, in a home setting.

Abstract
BACKGROUND We report here the first cohort study comparing regional and general anaesthesia for left subclavian artery (LSA) revascularization. METHODS A single-centre retrospective cohort study was performed, including all consecutive patients who underwent cervical debranching with carotid-subclavian bypass before aortic repair from February 2018 to May 2022. Patients were divided into 2 groups according to the type of anesthesia: Regional anesthesia (RA) versus general anesthesia (GA). Primary endpoints included the following: 1) technical success of RA and 2) neurological complications (NCs) (stroke and peripheral neurological lesions). Secondary endpoints included postoperative bleeding, wound complications, 30-day reintervention rate, and midterm events. RESULTS Eighty-three patients were included in the study. The mean age was 64 years (interquartile range [IQR]:13.5) and 69% were male. Thirty-seven patients (44.5%) were performed under RA. Technical success of RA was 89.2%. Two minor strokes (2.4%) were observed in the GA group (P = 0.199). Peripheral neurological disorders occurred in 4 patients (4.8%) (RA group n = 1 (2.7%), GA group n = 3 (6.5%), P = 0.491). 30-day complication rate was 27.7% (n = 23, GA: n = 15 (32.6%), RA: n = 8 (21.6%), P = 0.266). 30-day reintervention rate was 14.5% (n = 12) ten bleeding complications (12%) (RA group n = 3 (8.1%), GA group n = 7 (15.2%), P = 0.323), and 2 seroma evacuations (2.4%) in the RA group. The incidence of superficial wound infections was n = 6 (7.2%) (RA group n = 2 (5.4%), GA group n = 4 (8.7%), P = 0.565). Median follow-up time was 22 months (IQR 22 min/max 1-44). CONCLUSIONS In our cohort, RA for carotid subclavian bypass surgery proved to be a feasible and effective anesthetic procedure compared with GA.

Indian J Anaesth 2023; 67:579-589. [PMID: 37601928 PMCID: PMC10436725 DOI: 10.4103/ija.ija_806_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 04/18/2023] [Accepted: 04/18/2023] [Indexed: 08/22/2023] Open
Abstract
Background and Aims Thyroid surgery is moderately painful, and many techniques to reduce postoperative pain have been studied. Regional techniques are a part of multimodal analgesia employed for various surgical cases. Bilateral superficial cervical plexus block (BSCPB) is a commonly used regional anaesthesia technique for analgesia for thyroid surgery. A previous meta-analysis by this group had left questions about some facets of the technique, to which further trials have contributed. Methods The systematic review and meta-analysis was registered on the International Prospective Register of Systematic Reviews (PROSPERO) CRD42022315499. It is an update to a previously published paper in 2018. An updated systematic search, critical appraisal, and analysis of clinical trials were performed. Trials investigating preoperative or postoperative BSCPB compared to control in patients undergoing thyroid surgery were included in the search. The primary outcome was postoperative opioid consumption. The secondary outcomes were the duration of analgesia (time to request of analgesia), Visual Analogue Scale (VAS) pain scores at 0, 4, 12, and 24 h, postoperatively, rates of postoperative nausea and vomiting (PONV), postoperative rescue analgesic consumption, and intraoperative morphine use. Results A total of 31 studies and 2,273 patients were included in this analysis. BSCPB significantly reduced post-thyroidectomy opioid consumption (P < 0.001). Additionally, the duration of analgesia was prolonged following BSCPB. VAS scores for 24 h (postoperatively), intraoperative morphine use, and rescue analgesia (postoperatively) remained significantly lower in patients who received BSCPB. There was also a statistically significant reduction in PONV (P = 0.02). Conclusion BSCPB offers superior postoperative analgesia with a reduction in opioid use, reduction in PONV, and improvement in VAS scores.

Abstract
Peripheral nerve block technology is important to balanced anesthesia technology. It can effectively reduce opioid usage. It is the key to enhance clinical rehabilitation as an important part of the multimodal analgesia scheme. The emergence of ultrasound technology has accelerated peripheral nerve block technology development. It can directly observe the nerve shape, surrounding tissue, and diffusion path of drugs. It can also reduce the dosage of local anesthetics by improving positioning accuracy while enhancing the block's efficacy. Dexmedetomidine is a highly selective drug α2-adrenergic receptor agonist. Dexmedetomidine has the characteristics of sedation, analgesia, anti-anxiety, inhibition of sympathetic activity, mild respiratory inhibition, and stable hemodynamics. Numerous studies have revealed that dexmedetomidine in peripheral nerve blocks can shorten the onset time of anesthesia and prolong the time of sensory and motor nerve blocks. Although dexmedetomidine was approved by the European Drug Administration for sedation and analgesia in 2017, it has not yet been approved by the US Food and Drug Administration (FDA). It is used as a non-label drug as an adjuvant. Therefore, the risk-benefit ratio must be evaluated when using these drugs as adjuvants. This review explains the pharmacology and mechanism of dexmedetomidine, the effect of dexmedetomidine on various peripheral nerve block as an adjuvant, and compare it with other types of adjuvants. We summarized and reviewed the application progress of dexmedetomidine as an adjuvant in nerve block and look forward to its future research direction.

Abstract
INTRODUCTION In the present study, the advantages of superficial cervical plexus block (SCPB) were evaluated using a landmark-guided method. Our primary aim was to evaluate the analgesic efficacy of SCPB in various head and neck surgeries by observing intra- and postoperative requirements of the total dose of the systemic analgesic, visual analog scale (VAS) score, and the total duration of analgesia; vital parameters and associated perioperative complications were also observed. MATERIALS AND METHODS Sample size was calculated using reference by taking the parameter pain score at 12 hours using MedCalc software v. 19.5.1 (MedCalc Software, Ostend, Belgium) with a mean difference of score 3±3.5 between two groups, 80% power, and 95% confidence interval (CI); the sample size for each group was 21. There were 30 patients in each group of ASA I, II, and III who were posted for mandibular, tympanomastoid and clavicular surgeries. Group A received general anaesthesia with systemic analgesia and Group B received general anaesthesia followed by SCPB with an injection of bupivacaine 0.25% 10ml on each side according to the site of surgery. VAS score, intra and postoperative analgesic requirement in 24 hours, time of first demand bolus, and peri-operative complications were noted. RESULTS Intraoperative fentanyl requirement for group A was 97.5±13.75 µg as compared to group B (70.16±13.09 µg), postoperative injection paracetamol requirement was also significantly higher in group A (2566.66±504 mg) as compared to group B (833.33±874.28 mg). The total duration of analgesia was significantly higher in Group B (1191.33±375.36 min) as compared to Group A (122.0±50.88 min) with a p-value <0.0001. No significant complications were noted in any patient. CONCLUSION SCPB provides better perioperative analgesia by decreasing intraoperative as well as postoperative systemic analgesic requirements and their associated side effects, with no significant perioperative complications in various head and neck region surgeries.

A Randomized Controlled Trial. Clin Orthop Relat Res 2023; 481:798-807. [PMID: 36730478 PMCID: PMC10013610 DOI: 10.1097/corr.0000000000002479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Accepted: 10/11/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Variable innervation of the clavicle is a major challenge in surgery of clavicle fractures with patients under regional anesthesia. An interscalene block (ISB) combined with an intermediate cervical plexus block (ICPB) provides analgesia in clavicle fracture surgery, but this combination does not completely block sensation in the midshaft or medial clavicle. Cervical nerve root block is an alternative to deep cervical plexus block and has recently been used as an analgesic method in the neck and shoulder. Whether it should be used as an alternative for midshaft and medial clavicle fractures is unknown. QUESTIONS/PURPOSES In this randomized controlled trial, we compared a C3, 4, and 5 nerve root block to ISB combined with ICPB in surgery of midshaft and medial clavicle fractures in terms of the (1) proportion of patients achieving a sensory block that is sufficient for surgery, (2) onset time and duration of the block, and (3) effectiveness of postoperative analgesia, as measured by pain scores and consumption of analgesics. METHODS Between November 2021 and December 2021, we treated 154 patients for clavicle fractures. A total of 122 were potentially eligible, 91 of whom agreed to participate in this study. Twenty-nine patients were excluded because the patients chose general anesthesia or declined to undergo surgery. Ultimately, 62 patients were randomly allocated into the C3, 4, and 5 group or ISB + ICPB group, with 31 patients in each group; there were no dropouts. All patients were analyzed in the group they were randomized to under intention-to-treat principles. The assessor and patients were blinded to randomization throughout the trial. The two groups did not differ in any important ways, including age, gender, BMI, American Society of Anesthesiologists classification, and type of clavicle fracture. The two groups received either an ultrasound-guided C3, 4, and 5 nerve root block with 2, 3, and 5 mL of 0.5% ropivacaine or ultrasound-guided ISB with ICPB with 20 mL of 0.5% ropivacaine. The primary outcome was the proportion of patients in each group with a successful nerveba block who did not receive general anesthesia; this was defined as nerve block success. Secondary outcomes included the onset time and duration of the sensory block, defined as the onset to the moment when the patients felt pain and sought rescue analgesia; pain assessment in terms of the numeric rating scale (NRS) score (range 0 to 10) for pain after nerve block before and during surgery; and the median amount of sufentanil consumed intraoperatively and postoperatively in the recovery room. The dosing of sufentanil was determined by the assessor when the NRS score was 1 to 3 points. If the NRS score was more than 3 points, general anesthesia was administered as a rescue method. Complications after the two inventions such as toxic reaction, dyspnea, hoarseness, pneumothorax, and Horner syndrome were also recorded in this study. RESULTS A higher proportion of patients in the C3, 4, and 5 group had a successful nerve block than in the ISB + ICPB group (97% [30 of 31] versus 68% [21 of 31], risk ratio 6 [95% CI 1.5 to 37]; p < 0.01). The median onset time was 2.5 minutes (range 2.0 to 3.0 minutes) in the C3, 4, and 5 group and 12 minutes (range 9 to 16 minutes) in the ISB + ICPB group (difference of medians 10 minutes; p < 0.001). The sensory block duration was 10 ± 2 hours in the C3, 4, and 5 group and 8 ± 2 hours in the ISB + ICPB group (mean difference 2 hours [95% CI 1 to 3 hours]; p < 0.001). The median sufentanil consumption was lower in the C3, 4, 5 group than in the ISB + ICPB (median 5 µg [range 0.0 to 5.0 µg] versus median 0 µg [range 0.0 to 0.0 µg]; difference of medians 5.0 µg; p < 0.001). There were no differences between the two groups regarding NRS scores after nerve blocks and NRS score for incision and periosteum separation, with the minimum clinically important difference set at a 2-point difference (of 10). There were no severe complications in this study. CONCLUSION Based on our analysis of the data, a C3, 4, and 5 nerve root block was better than ISB combined with ICPB for surgery to treat medial shaft and medial clavicle fractures. When choosing the anesthesia method, however, the patient's basic physiologic condition and possible complications should be considered. LEVEL OF EVIDENCE Level I, therapeutic study.

Abstract
Dysfunctions of the sternocleidomastoid (SCM) muscle, such as myofascial syndrome, torticollis, and cervical dystonia, have been treated using several invasive procedures. In such situations, it is possible to injure the adjacent nerves. This study aimed to demonstrate the course of these nerves in healthy volunteers using ultrasound. The great auricular nerve (GAN), spinal accessory nerve (SAN), transverse cervical nerve (TCN), and supraclavicular nerve (SCN) were scanned by ultrasonography in 26 healthy volunteers. The neck was scanned in the supine position with the head turned 45° to the contralateral side. The cervical plexus was detected in half of the SCM muscle. Each nerve was then traced to the level of contact with the anterior border of the SCM muscle. The following features of the nerves were recorded bilaterally: vertical and horizontal positions of each nerve at the posterior border of the SCM and the cross-sectional area and depth of each nerve at the reference line and anterior border of the SCM. The mean proportions of GAN, SAN, TCN, and SCN were 26%, 26%, 48%, and 80%, respectively near the posterior border, whereas they were 18%, 23%, and 51% for GAN, SAN, and TCN, respectively, at the level of the reference line. Notably, SCN was not visible at the level of the reference line. The mean TCN proportion was 47% at the anterior border of the SCM. The precise location of the nerves and their relationship with the SCM muscle should be considered during invasive procedures. It is recommended that the procedure be performed in the lower half of the SCM muscle, which refers to 50 to 80% of the proportions in our study.

Abstract
Background and Aims Opioids are conventionally used for post-thyroidectomy pain, regional anesthesia is becoming popular due to its feasibility and efficacy in minimizing use of opioids and hence its side effects. This study compared analgesic efficacy of bilateral superficial cervical plexus block (BSCPB) using perineural and parenteral dexmedetomidine with 0.25% ropivacaine in thyroidectomy patients. Material and Methods In this double-blind study, 60 American Society of Anesthesiologists (ASA) physical status I and II thyroidectomy patients, aged 18-65 years were randomized into two groups. Group A (n = 30) received BSCPB with 0.25% ropivacaine, 10 mL on each side with dexmedetomidine 0.5 μg/kg IV infusion. Group B (n = 30) received 0.25% ropivacaine plus dexmedetomidine 0.5 μg/kg, ten mL on each side. Duration of analgesia by measuring pain visual analog scores (VAS), total dose of analgesic requirement, Haemodynamics parameters and adverse events were recorded for 24 h. Categorical variables were analyzed using Chi-square test and continuous variables were computed as mean with standard deviation and analyzed using independent sample t-test. Mann-Whitney U test was used for analysis of ordinal variables. Results Time to rescue analgesia was longer in Group B (18.6 ± 3.27 h) as compared to Group A (10.2 ± 2.11 h) (P < 0.001). Total analgesic dose required was also found to be lesser in Group B (50.83 ± 20.37 mg) as compared to Group A (73.33 ± 18.27 mg) (P < 0.001). No significant hemodynamic changes or side effects were observed in both groups; (P > 0.05). Conclusion Perineural dexmedetomidine with ropivacaine in BSCPB significantly prolonged the duration of analgesia with reduced rescue analgesic requirement.

Abstract
Patients undergoing vascular surgery tend to have significant systemic comorbidities. Vascular surgery itself is also associated with greater cardiac morbidity and overall mortality than other types of noncardiac surgery. Regional anesthesia is amenable as the primary anesthetic technique for vascular surgery or as an adjunct to general anesthesia. When used as the primary anesthetic, regional anesthesia techniques avoid complications associated with general anesthesia in this challenging patient population. In this article, the authors describe regional anesthetic techniques for carotid endarterectomy, arteriovenous fistula creation, lower extremity bypass surgery, and amputation.

Abstract
A 35-year-old female patient was scheduled for a left hemithyroidectomy. We performed bilateral cervical plexus blocks with ultrasound guidance for an awake thyroidectomy. Soon after the blocks, she developed a weak voice, which gradually progressed to complete aphonia. Due to her apprehension, general anesthesia was administered. After an uneventful surgery, the patient spontaneously regained her normal voice in the postoperative period. The case report describes a previously unreported complication of aphonia presumably due to bilateral recurrent laryngeal nerve blocks, which might have occurred from the infiltrated local anesthetic extravasating to the deeper planes through the cervical fascia.

Abstract
Cervical traumatic neuromas (CTNs) are a non-neoplastic hyperplasia of damaged nerves and may be misinterpreted as metastatic lymph nodes during cervical ultrasound of patients with thyroid cancer after lateral neck dissection, resulting in unnecessary and painful fin-needle aspiration biopsy. The anatomy of the cervical plexus is challenging, and the correct identification and recognition of its neural roots and branches on ultrasound are key to the correct CTN diagnosis. This review outlines the US technique used to characterize CTNs in 10 standardized steps and describes the sonographic features of the cervical plexus, to assist the radiologist in the recognition of CTNs and their differentiation from lymph node metastases.

Abstract
BACKGROUND Under the background that cervical plexus block (CPB) is often adopted for type I thyroid cartilage laryngoplasty (TCL) and vocal cord medialization (VCM), the present study sought to investigate whether ultrasound-guided CPB (USCPB) could improve the efficiency of type I TCL and VCM. METHODS Patients with TCL were enrolled and subjected to deep and superficial USCPBs. Intravenous dexmedetomidine pumping was used to assist the painless sedation and ensure the patients to be awake for phonation during surgery. Blood pressure, electrocardiogram, heart rate (HR), and blood oxygen saturation (SpO2) of patients were recorded. The complications, like local anesthetic toxicity and total spinal anesthesia, were monitored. RESULTS All patients underwent CPB without infiltration anesthesia and complication. The use of Sufentanil at the dose of 5-10 μg was reported in 2 of 15 patients. No Horner syndrome was discovered in patients after anesthesia, and total intravenous anesthesia with intravenous pumping of dexmedetomidine was effective. During surgery, HR, diastolic blood pressure and mean blood pressure were barely changed, but systolic blood pressure was decreased. CONCLUSION Ultrasound-guided CPB with the intravenous dexmedetomidine pumping is a safe anesthesia method for patients during TCL.

Abstract
With the extensive application of ultrasound in regional anesthesia, there has been rapid development of interfascial plane block techniques recently. Compared with neuraxial anesthesia or nerve plexus blocks, the interfascial plane blocks have many advantages, such as technical simplicity, fewer complications and comparable or better analgesia. The concept of fascial interconnectivity is fundamental in understanding the effects and complications of interfascial plane blocks. Many fascial planes are continuous and communicate with each other without a clear anatomical boundary. The prevertebral fascia of the neck, endothoracic fascia of the chest, transversalis fascia of the abdomen, and the fascia iliaca of the pelvic cavity form a natural fascial continuation. This anatomical feature suggests that the space beneath the cervical prevertebral fascia, the thoracic paravertebral space, the space between transversalis fascia and psoas muscles (psoas major and quadratus lumborum), and the fascia iliaca compartment are a confluent potential cavity. Additionally, the permeability of the fascia at different anatomical locations to local anesthetics is different, which can also influence the block effect and the incidence of complications. This article summarizes the anatomical characteristics and communication relationships of the major fascia which are related to regional anesthesia, and their relationships with block effects and complications.

Abstract
BACKGROUND Primary hyperparathyroidism (PHPT) is the most common cause of pregnancy-related hypercalcemia. PHPT can cause maternal and fetal complications in pregnant women. General anesthesia for non-obstetric surgery in pregnant women is associated with maternal hazards and concerns regarding long-term neonatal neurocognitive effects. Surgical removal of the lesion in mid-pregnancy is currently the primary treatment option for pregnant patients with PHPT. However, the blood calcium concentration at which surgery should be considered remains under discussion due to the risk of miscarriage.
CASE SUMMARY A 31-year-old nulliparous woman at 11 wk of gestation was admitted to our hospital for parathyroidectomy. The patient had a history of intrauterine fetal death with unknown etiology at 16 wk of gestation 1 year prior. Her blood test results showed that the serum calcium level was elevated to 12.9 mg/dL, and the parathyroid hormone level was elevated to 157 pg/mL. In a neck ultrasound, it revealed a 0.8 cm × 1.5 cm sized oval, hypoechoic mass in the upper posterior of the left thyroid gland, which was compatible with parathyroid adenoma. Superficial cervical plexus block (SCPB) for parathyroidectomy was performed. After surgery, the obstetrician checked the status of the fetus, and there were no abnormal signs. Since then her calcium level returned to normal values after one week of surgery and a healthy male neonate of 2910 g was delivered vaginally at 38 wk of gestation.
CONCLUSION Our case suggests that SCPB can be an anesthetic option for parathyroidectomy during the first trimester of pregnancy.

Abstract
The superficial cervical plexus block (SCPB) is well acknowledged, accepted for regional anesthetic for the submandibular area, neck region, and ear lobe. It is a possible valuable anesthetic technique in individuals to be operated on with conditions such as ear lobe lacerations, submandibular abscesses, and trauma to the mandibular or the neck region. Its application in oral and maxillofacial surgery is for various surgical procedures in the peri-mandibular area, excision of superficial lesions in the mandibular, ear lobe, neck region, and suturing of the skin in the corresponding region. We illustrate a case of non-union of mandibular fracture operated under superficial cervical plexus block without any complications.

Abstract
Avoidance of general anesthesia and endotracheal intubation has been shown to reduce respiratory complications in patients with severe lung disease. We describe the case of a 75-year-old patient with chronic obstructive pulmonary disease (COPD) who underwent cochlear implantation managed with nerve block and sedation. A superficial cervical plexus block (SCPB) was performed with 1% mepivacaine before surgery. A small amount of intravenous analgesic and sedative was administered. The patient experienced only slight pain during surgery. A SCPB had a good analgesic effect on the posterior auricle. Cochlear implantation in patients with COPD can be performed using a SCPB and sedation.

Abstract
Cervicogenic headache is a clinical condition that has a direct impact on quality of life and labor productivity and its underdiagnosis and lack of consensus on the appropriate treatment aggravates even more the condition. This work aims to systematize the protocol that has the highest success rate so far, based on the study carried out in Pindamonhangaba, São Paulo, Brazil. The results demonstrated with the occipital block and Maitland physiotherapy were exceptional and its methodology will be carried out as performed during the study.
Conclusion: Regardless of the substance used for the blockade, its combination with Maitland's physiotherapy was shown to be favorable and its description can help other professionals and also enable reproduction in other studies.

Abstract
Intraoperative stress is common to patients undergoing carotid endarterectomy (CEA); thus, impaired oxygen and metabolic balance may appear. In this study, we aimed to identify new markers of intraoperative cerebral ischemia, with predictive value on postoperative complications during CEA, performed in regional anesthesia. A total of 54 patients with significant carotid stenosis were recruited and submitted to CEA. Jugular and arterial blood samples were taken four times during operation, to measure the jugulo-arterial carbon dioxide partial pressure difference (P(j-a)CO2), and cortisol, S100B, L-arginine, and lactate levels. A positive correlation was found between preoperative cortisol levels and all S100B concentrations. In addition, they are positively correlated with P(j-a)CO2 values. Conversely, postoperative cortisol inversely correlates with P(j-a)CO2 and postoperative S100B values. A negative correlation was observed between maximum systolic and pulse pressures and P(j-a)CO2 after carotid clamp and before the release of clamp. Our data suggest that preoperative cortisol, S100B, L-arginine reflect patients' frailty, while these parameters postoperatively are influenced by intraoperative stress and injury. As a novelty, P(j-a)CO2 might be an emerging indicator of cerebral blood flow during CEA.

Abstract
Background and Aims: Intravenous analgesics and local infiltration are used for postoperative analgesia in patients undergoing mastoidectomy. No randomised controlled trial (RCT) has so far determined response rates of pain reduction after ultrasound-guided superficial cervical plexus block (SCPB) in adult patients undergoing modified radical mastoidectomy. Methods: This double-blind RCT was conducted in 30 adult patients of the American Society of Anesthesiologists (ASA) grade I/II undergoing modified radical mastoidectomy. The primary outcome was a reduction in the visual analogue scale (VAS) score. Secondary outcomes were postoperative diclofenac consumption, haemodynamics, and occurrence of any adverse events. All patients received general anaesthesia. At the end of the surgery, patients were randomised to either Group ‘Block’ (n = 15) ultrasound guided SCPB with 5 mL ropivacaine 0.5% or Group ‘No block’ (n = 15). All patients received intravenous (IV) paracetamol 1 g every 6 hourly and rescue analgesic IV diclofenac 75 mg if VAS score >4. Results: Patients in Group ‘Block’ reported lower VAS score at rest versus Group ‘No block’ at 1 h postoperatively (P = 0.012). VAS score on movement was lower in patients of Group ‘Block’ compared to Group ‘No block’ at 1 h (P = 0.010), 4 h (P = 0.035), 8 h (P = 0.027), and 12 h (*P = 0.003) postoperatively. Diclofenac consumption was lower in patients of Group ‘Block’ (P = 0.041). No adverse effects were reported. Conclusion: Postoperative ultrasound-guided SCPB produced higher response rates in terms of reduction in VAS score in patients undergoing modified radical mastoidectomy.

Abstract
BACKGROUND Cervical abscesses frequently occurred in pediatric patients. Surgical drainage is currently recommended in the cases not responding to medical therapy. Needle aspiration may represent a simple, effective and minimally invasive treatment for acute neck suppuration in selected cases. OBJECTIVE To evaluate the effectiveness of needle aspiration in the treatment of cervical abscesses in pediatric age as an alternative to surgical drainage. METHODS From November 2013 to November 2019, at the ENT Department of the "Bambino Gesù" Pediatric Hospital, Rome, we treated 47 children with cervical abscess by performing aspiration with a 19 G needle in wakefulness after applying local anesthetic. Parenteral antibiotic treatment was associated with all patients both before and after treatment. RESULTS Complete regression of the abscess occurred in 46 children with no evidence of recurrence in the follow-up period. Surgical drainage was required in only one patient due to the lack of resolution of the abscess episode. No complications such as hematomas or hypertrophic scars were found in any patient. CONCLUSIONS Our results confirm the effectiveness of needle aspiration in the treatment of cervical abscesses in children as an alternative to surgical drainage.

Abstract
One of major causes of cervical central stenosis (CCS) is thickened change of cervical ligament flavum (CLF). The association of a morphological parameter called cervical ligament flavum thickness (CLFT) with CCS has not been reported yet. Thus, the purpose of this research was to investigate the relationship between CCS and CFJT.Data were obtained from 88 patients with CCS. A total of 87 normal controls also underwent cervical spine magnetic resonance imaging (CSMRI). All subjects underwent axial T2-weighted CSMRI. Using our picture archiving and communications system, thickness of ligament flavum of the cervical spine at C6/7 level was analyzed.The mean CLFT was 1.41 ± 0.24 mm in normal subjects and 2.09 ± 0.39 mm in patients with CCS. The CCS group was found to have significantly (P < .001) higher rate of CLFT than normal subjects. ROC curves were used to assess the usefulness of CLFT as a predictor of CCS. In the CCS group, the best practical cut off-point of CLFT was 1.71 mm (sensitivity = 90.9%; specificity = 90.8%), with AUC of 0.94 (95% confidence interval: 0.90--0.98).Greater CLFT values were associated with greater possibility of CCS. Thus, treating physician should carefully examine CLFT, as it can help diagnose CCS.

Abstract
PURPOSE Infiltration techniques are used as an adjuvant to regional anesthesia. In this study, we evaluated the efficacy of the superficial cervical plexus nerve block, as an alternative to local infiltration techniques; in the management of mandibular fractures and peri-mandibular space infections. METHODS A prospective randomized controlled trial was conducted on 24 patients having either mandibular fractures or peri-mandibular space infections; and were scheduled for surgery under regional anesthesia (eg, inferior alveolar nerve block, long buccal nerve block). The control group involved delivering a combination of regional anesthesia along with local infiltration. The experimental group received regional anesthesia with a superficial cervical plexus nerve block. The following parameters were studied: pain, onset and duration of anesthesia, time interval until first analgesic request, pulse rate and blood pressure [at different time intervals]. RESULTS Intergroup comparison was done using unpaired t-test. Intragroup comparison was done using repeated measures ANOVA (for >2 observations), followed by a post hoc test. The superficial cervical plexus nerve block group showed highly statistically significant (P < .01) improvement in terms of intra-operative pain at 30 minutes, duration of anesthesia, intraoperative anesthetic requirement, time interval until first analgesic request and intraoperative diastolic blood pressure at 10 minutes. CONCLUSION It can be concluded that the combination of a regional anesthesia technique with a superficial cervical plexus nerve block is an alternative and safe technique for patients undergoing surgery for mandible fractures and perimandibular space infections, with clear advantages over local infiltration.

Abstract
Pregnant patients with high-risk conditions including abnormal placentation or severe cardiovascular disease may require large-bore central venous access at the time of delivery. Central lines are generally inserted while obstetric patients are awake, either because neuraxial anesthesia is planned or to minimize fetal exposure to anesthetic medications. Despite local infiltration, the procedure can cause significant patient discomfort. This case series describes use of a superficial cervical plexus block (SCPB) to facilitate line placement in 4 pregnant women with high-risk conditions. SCPB is technically straightforward with low reported complication rates and should be considered for pregnant patients requiring large-bore central lines.

Abstract
BACKGROUND Clavicular fractures are commonly encountered in the emergency department (ED). Fracture pain is usually treated with nonsteroidal anti-inflammatory drugs (NSAID) and opioids; however, both of these drug classes have potentially significant side effects that limit their use in certain patient populations. Hematoma blocks are safe and effective alternatives for pain control. CASE REPORT We present the case of a 39-year-old healthy man that presented to the ED with a clavicular fracture after a fall from a motorized scooter. He received minimal pain relief from hydrocodone-acetaminophen. A hematoma block was subsequently performed, with significant improvement in his pain. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Hematoma blocks are safe and effective treatments for clavicular fracture pain in the ED without the potentially significant side effects of NSAIDs and opioids.

Abstract
Cervical plexus nerve blocks have been employed in various head and neck operations. Both adequate anaesthesia and analgesia are attained in clinical practice. Nowadays, ultrasound imaging in regional anaesthesia is driven towards a certain objective that dictates high accuracy and safety during the implementation of peripheral nerve blocks. In the cervical region, ultrasound-guided nerve blocks have routinely been conducted only for the past few years and thus only a small number of publications pervade the current literature. Moreover, the sonoanatomy of the neck, the foundation stone of interventional techniques, is very challenging; multiple muscles and fascial layers compose a complex of compartments in a narrow anatomic region, in which local anaesthetics are injected. Therefore, this review intends to deliver new insights into ultrasound-guided peripheral nerve block techniques in the neck. The sonoanatomy of the cervical region, in addition to the cervical plexus, cervical ganglia, superior and recurrent laryngeal nerve blocks are comprehensively discussed.

Abstract
Branchial arches are embryologic structures that develop between the fourth and seventh gestational week. Anomalies may form if these structures fail to develop. The majority of cases are diagnosed during childhood, with surgical excision recommended to prevent risk of infection, growth or malignancy. We report an unusual case of a 72-year-old man with severe cardiac comorbidities who presented with a large second branchial arch cyst extending into the oropharynx. General anaesthesia to facilitate surgical excision was deemed too risky. Therefore, we performed successful ultrasound-guided superficial and deep cervical plexus blocks as a sole mode of anaesthesia. This case highlights how regional anaesthesia can be utilised to facilitate surgery in high-risk patients, as well as presenting an alternative for general anaesthesia.

Abstract
BACKGROUND The role of type I thyroplasty (TIP) is well established as the treatment for glottal insufficiency due to vocal fold paralysis, but the ideal anesthetic management for this procedure is still largely debated. We present the case of a novel anesthetic approach for TIP using combined intermediate and superficial Cervical Plexus Block (CPB) and intermittent mild sedation analgesia. CASE REPORT A 51-year-old presenting with left vocal fold paralysis and obstructive sleep apnea was scheduled for TIP. An ultrasound-guided intermediate CPB was performed using the posterior approach, and 15 mL of ropivacaine 0.5% were injected in the posterior cervical space between the sternocleidomastoid muscle and the prevertebral fascia. Then, for the superficial CPB, a total of 10 mL 0.5% ropivacaine was injected subcutaneously, adjacently to the posterior border of the sternocleidomastoid muscle, without penetrating the investing fascia. An intermittent sedation analgesia with a target-controlled infusion of remifentanyl (target 0.5 ng.mL-1) was used to facilitate prosthesis insertion and the fiberoptic laryngoscopy. This technique offered a safe anesthetic airway and good operating conditions for the surgeon, as well as feasible voice monitoring and optimal patient comfort. CONCLUSION The use of regional technique is a promising method for the anesthetic management in TIP, especially in patients with compromised airway.

Abstract
BACKGROUND The complex innervation of the clavicle makes general anaesthesia a preferred technique for clavicular surgeries in current practice. The role and approach of regional anaesthesia remains unanswered. OBJECTIVES This study aims to delineate the relative effectiveness between interscalene brachial plexus block with either intermediate cervical plexus or superficial cervical plexus block (CPB) as the anaesthetics for clavicular surgery. DESIGN A randomised, double-blind prospective study. SETTING Single-centre, tertiary care medical college and research institute. PATIENTS Fifty patients with American Society of Anesthesiologist's (ASA) grade I to III, aged 18 to 70 years, scheduled for clavicular surgery, during May 2018 to April 2019 were enrolled in this study. INTERVENTION All patients received interscalene block with 10 ml of 0.5% bupivacaine. Patients were randomised to undergo additional ultrasound-guided intermediate CPB (Group-1) or superficial CPB (Group-2) with 10 ml of 0.5% bupivacaine. MAIN OUTCOME MEASURES The block success rate, sensory block onset time, haemodynamic parameters, duration of postoperative analgesia and complications were noted. Categorical data were analysed using the chi-square test and Fisher's exact test. Continuous data were analysed using Student's t-test. RESULT In Group 1, block success was 100%. In Group 2, five patients failed to achieve adequate surgical anaesthesia (P = 0.02). The average sensory block onset time in Group 1 was 2.5 ± 0.4 min and was longer in Group 2, 4.3 ± 0.5 min (P < 0.001). There was no difference between the groups with respect to haemodynamic parameters and complications. The mean duration of postoperative analgesia was longer in Group 1 (7.5 ± 0.8 h) as compared with Group 2 (5.7 ± 0.4 h, P < 0.001). CONCLUSION Ultrasound-guided combined interscalene and intermediate CPB had a better success rate, with faster sensory block onset time and prolonged postoperative analgesia as compared with interscalene and superficial CPB in patients undergoing clavicle surgery.

Abstract
Regional anesthesia has been an undervalued entity in neuroanesthetic practice. However, in the past few years, owing to the development of more advanced techniques, drugs and the prolific use of ultrasound guidance, the unrecognised potential of these modalities have been highlighted. These techniques confer the advantages of reduced requirements for local anesthetics, improved hemodynamic stability in the intraoperative period, better pain score postoperatively and reduced analgesic requirements in the postoperative period. Reduced analgesic requirement translates into lesser side effects associated with analgesic use. Furthermore, the transition from the traditional blind landmark-based techniques to the ultrasound guidance has increased the reliability and the safety profile. In this review, we highlight the commonly practised blocks in the neuroanesthesiologist's armamentarium and describe their characteristics, along with their individual particularities.

Abstract
PURPOSE An intermediate cervical plexus block (CPB) targets the posterior cervical space between the sternocleidomastoid muscle and the prevertebral fascia. The phrenic nerve descends obliquely on the surface of the anterior scalene muscle beneath the prevertebral fascia after originating from the C3-C5 ventral rami. Therefore, the phrenic nerve can be affected by a local anesthetic during an intermediate CPB, depending on the permeability characteristics of the prevertebral fascia. This study investigated whether an intermediate CPB affects the phrenic nerve, inducing hemidiaphragmatic paresis. METHODS In this prospective observational study, 20 patients undergoing single-incision transaxillary robot-assisted right thyroidectomy were enrolled. The intermediate CPB (0.25% ropivacaine 0.2 ml/kg) was performed at the C4-5 intervertebral level carefully, without penetrating the prevertebral fascia, before the patient emerged from general anesthesia. Diaphragmatic motions of the block side were measured by M-mode ultrasonography at three time points: before anesthesia (baseline) and at 30 and 60 min after the intermediate CPB. Hemidiaphragmatic paresis was divided into three grades, depending on the percentage of diaphragm movement compared to the baseline: none (> 75%), partial paresis (25-75%), and complete paresis (< 25%). RESULTS No patient showed any partial or complete ipsilateral hemidiaphragmatic paresis within 60 min after the intermediate CPB. CONCLUSION Intermediate CPB using 0.2 ml/kg of 0.25% ropivacaine at the C4-5 intervertebral level did not cause ipsilateral hemidiaphragmatic paresis. This may imply that the effect of the intermediate CPB on the phrenic nerve is not significant.

Abstract
A 28-year-old woman presented for excision of a left-sided pleuropulmonary sarcoma which was adherent to her left subclavian artery and mediastinum. A left upper lobe wedge resection was performed via a median sternotomy and a left carotid artery-to-left subclavian artery bypass was performed through a left supraclavicular incision. We report on a triple regional anaesthesia technique to provide postoperative analgesia. We inserted bilateral transverse thoracic plane catheters for continuous local anaesthetic infusion and performed bilateral subcostal transversus abdominus plane blocks for drain site analgesia. A left superficial cervical plexus block was performed to cover pain from the supraclavicular incision. Anteromedial chest wall blocks are an emerging analgesic technique for sternotomy and were successfully used as part of a combined regional anaesthetic for a patient undergoing complex thoracic surgery.

Comparison of ultrasound-guided intermediate vs subcutaneous cervical plexus block for postoperative analgesia in patients undergoing total thyroidectomy: A randomised double-blind trial. Indian J Anaesth 2020; 64:37-42. [PMID: 32001907 PMCID: PMC6967358 DOI: 10.4103/ija.ija_483_19] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2019] [Revised: 08/24/2019] [Accepted: 11/05/2019] [Indexed: 01/20/2023] Open
Abstract
Background and Aims: Intermediate cervical plexus block (CPB) is a new procedure whose analgesic efficacy compared to superficial cervical plexus block is yet to be established. We compared the analgesic efficacy of superficial vs intermediate CPB for post-operative analgesia after thyroid surgery. Methods: Forty-five patients with American Society of Anaesthesiologists' physical status 1 or 2 undergoing total thyroidectomy were recruited. Forty-four patients in superficial/subcutaneous CPB group (n = 22) and intermediate CPB (n = 22) received 20 mL 0.25% bupivacaine with adrenaline 100 μg bilaterally in ultrasound-guided superficial and intermediate cervical plexus block before induction of general anaesthesia., respectively. The primary outcome measure was the postoperative visual analogue scale (VAS) scores at 0, 2, 4, 6, 12 and 24. Secondary outcome measures included the total dose of rescue analgesic required, duration of postoperative analgesia and patient's satisfaction score. Statistical analysis was with the Mann-Whitney U test and independent t-test. Results: The post-operative VAS scores were lower in intermediate CPB group compared to superficial CPB group at 2, 4, 6, 12, 18 and 24 h [P < 0.05]. Time tofirst rescue analgesic demand was prolonged 10.06 ± 3.62 h in intermediate group compared to 7.94 ± 3.62 h in superficial group [P = 0.017] and total analgesic consumption were lower in intermediate group (71.25 ± 16.70 μg) than the superficial group (101.25 ± 50.31 μg) [P = 0.011]. Conclusion: Ultrasound-guided intermediate CPB reduces post-operative pain scores, prolongs duration of analgesia and decreases demands for rescue analgesia compared to superficial CPB.

Abstract
Persistent cervicothoracic myofascial pain is a common condition that causes loss of function and can result in significant health care costs. The underlying cause is tender trigger points that result in impaired muscle function. Standard treatment includes physiotherapy, medications, acupuncture, and trigger point injections. Patients who fail to respond have very limited treatment options. The authors present a novel treatment in 2 patients presenting with severe unilateral cervicothoracic myofascial neck pain that failed to respond to standard treatment. The novel treatment, ultrasound-guided intermediate cervical plexus block with depot steroids, produced significant and durable pain relief in the 2 patients.

Abstract
Chronic pain management techniques have evolved in recent years. With regard to this, ultrasound (US) technology has become a standard for most acute pain procedures and essential for postsurgical pain relief and enhanced recovery after surgery protocols. This manuscript summarizes clinical studies evaluating US use for chronic pain management and compares efficacy with standard techniques including fluoroscopy (FL). US possesses several unique benefits when compared with FL, including elimination of radiation exposure while providing similar clinical outcomes. In summary, US use for chronic pain procedures is emerging as a viable, safe, and effective modality. Additional studies are needed to best appreciate US and its role in chronic pain management.

Abstract
Purpose: One of the main factor of cervical foraminal stenosis (CFS) is the hypertrophic change of the cervical facet joint. In order to analyze the connection between CFS and the facet joint hypertrophy, we devised a new morphological parameter, called the cervical facet joint cross-sectional area (CFJA). The CFJA has not yet been investigated for its association with CFS. We hypothesized that the CFJA is an important morphologic parameter in the diagnosis of CFS. Patients and methods: All patients over 50 years of age were included. Data regarding the CFJA were collected from 160 subjects with CFS. A total of 162 control individuals underwent cervical spine magnetic resonance imaging (CMRI) as part of a routine medical examination. Axial T2-weighted CMRI images were acquired from all subjects. We used a picture archiving system to analyze the cross-sectional area of the bone margin of the cervical facet joint at the level of the most stenotic cervical spine in the axial plane. Results: The average CFJA was 109.07±20.91 mm2 in the control group, and 126.75±22.59 mm2 in the CFS group. The CFS group was found to have significantly higher levels of the CFJA (p<0.001) than the control group. ROC curve estimation was used to verify the validity of the CFJA as a new predictor of CFS. In the CFS group, the best cut off-point was 113.14 mm2, with sensitivity =70.6%, specificity =68.6%, and AUC =0.72 (95% CI, 0.66–0.77). Conclusions: CFJA high values were closely associated with a possibility of CFS. We concluded CFJA is easy to use, fast, and useful new morphological parameter to predict CFS.
