Post-thyroidectomy bilateral cervical plexus block relieves pain: a systematic review.

PURPOSE: To assess the effectiveness of bilateral superficial cervical plexus block (BSCPB) in treating post-thyroidectomy pain. METHODS: MEDLINE, Embase, Google Scholar, LILACS, and the Cochrane Central Register of Controlled Trials, were extensively searched. The search period extended from 1968 until December 2022. Randomized controlled trials comparing BSCPB to placebo, no block in patients with thyroidectomy for benign or malignant thyroid disease were included. Outcomes were pain in the first 24 h after surgery. Analgesic rescue, period before the first rescue dosage, and 24-h opioid usage were secondary outcomes. The RoB 2 instrument was used to evaluate the risk of bias. RESULTS: 34 of 354 studies were eligible. There were 2,519 patients. BSCPB reduced the intensity of pain postoperatively [SMD: - 1.17 (95% CI: - 1.54 to - 0.81)] and in the first 24 h [- 0.62 (95%: 0.91 to 0.33)]. A considerable delay for the first opioid dose, rescue analgesics, and postoperative opioid usage was also found. CONCLUSION: BSCPB's 24-h analgesic efficacy minimizes the requirement for rescue analgesia, postoperative opioid intake, and rescue analgesia start time. The choice of anesthetic and different application methods might affect its effectiveness.

Regional analgesia using ultrasound-guided intermediate cervical plexus block versus cervical erector spinae block for anterior cervical spine surgery: a randomized trial.

BACKGROUND: Regional analgesia techniques are crucial for pain management after cervical spine surgeries. Anesthesiologists strive to select the most effective and least hazardous regional analgesia technique for the cervical region. Our hypothesis is that an intermediate cervical plexus (IC) block can provide adequate postoperative analgesia compared to a cervical erector spinae (ES) block in patients undergoing anterior cervical spine surgery. METHODS: In this double-blind prospective trial, 58 patients were randomly assigned into two equal groups prior to the administration of general anesthesia. Patients in the IC group (n = 29) underwent ultrasound-guided bilateral intermediate cervical plexus block with 15 ml of bupivacaine 0.25% administered to each side. The ES group (n = 29) underwent ultrasound-guided bilateral cervical erector spinae plane blocks with 15 ml of 0.25% bupivacaine administered to each side at the C6 level. The primary outcome was to record the time to the first call for rescue analgesia (nalbuphine), and the secondary outcomes were to measure the performance time, the onset of the sensory block, the intraoperative fentanyl consumption, postoperative pain intensity using VAS, the postoperative total nalbuphine consumption, and postoperative complications such as nausea, vomiting, hypotension, and bradycardia. RESULTS: The performance and onset of sensory block times were significantly shorter in the IC group compared to the ES group. The time to first call for nalbuphine was significantly shorter in the IC group (7.31 ± 1.34 h) compared to the ES group (11.10 ± 1.82 h). The mean postoperative VAS scores were comparable between the two groups at the measured time points, except at 8 h, where it was significantly higher in the IC group, and at 12 h, where it was significantly higher in the ES group. The total nalbuphine consumption was significantly higher in the IC group (33.1 ± 10.13 mg) compared to the ES group (22.76 ± 8.62 mg). CONCLUSIONS: For patients undergoing anterior cervical spine surgery, the intermediate cervical plexus block does not provide better postoperative regional analgesia compared to the cervical erector spinae block. Performance time and onset time were shorter in the IC group, whereas nalbuphine consumption was lower in the ES group. TRIAL REGISTRATION: The trial was registered at clinicaltrials.gov. (NCT05577559, and the date of registration: 13-10-2022).

Analgesic effects of pectoserratus plane block and intermediate cervical plexus block for transaxillary endoscopic thyroidectomy: a prospective randomized controlled trial.

BACKGROUND: Transaxillary endoscopic thyroidectomy (TAET) is favored for its favorable cosmetic outcomes and the preservation of anterior cervical function. Despite these benefits, postoperative analgesia has traditionally relied on pharmacological interventions, and regional anesthetic procedures may be an alternative method. This study aimed to evaluate the efficacy of an ultrasound-guided pectoserratus plane block (PSPB) combined with an intermediate cervical plexus block (ICPB) for TAET. METHODS: Forty patients undergoing TAET were randomized into two groups: the nerve block group (N.=20) received ultrasound guided PSPB with 20 ml of 0.375% ropivacaine and ICPB with 8 mL of 0.3% ropivacaine, while the control group (N.=20) received no block. The primary outcome was the Visual Analog Scale (VAS) scores for postoperative neck and axillary pain at different time points (1, 6, 12, 24 h) during rest and movement post-TAET. The secondary outcomes included intraoperative remifentanil consumption, incidence of postoperative nausea and vomiting (PONV), number of remedial analgesic requirements, and patient satisfaction postoperatively. RESULTS: Compared to the control group, patients in the nerve block had significantly lower VAS scores of the neck and axilla whether at rest or movement, and 1, 6, 12, and 24 h postoperatively (P<0.0125). The nerve block group showed higher patient satisfaction (P<0.001). No difference was observed in intraoperative remifentanil consumption, need for rescue analgesics, or other adverse effects 48 h postoperatively. CONCLUSIONS: Ultrasound-guided PSPB with ICPB significantly alleviated postoperative pain and improved patient satisfaction with TAET.

Achieving the minimum pain experience by buccal nerve and superficial cervical plexus blocks in radiofrequency treatment.

BACKGROUND: Thermage is a monopolar radiofrequency (RF). It has become an indispensable part of facial and body youthful methods. Although the current device is constantly improving in epidermal cooling techniques and even automatically measures the local impedance value, applying surface anesthesia can take some of the pain away caused by thermage, and the patient's severe pain in the jaw and neck areas is still difficult to resolve. METHODS: The author describes how he uses the combination of the buccal nerve block (BNB) and the superficial cervical plexus block (SCPB) to improve the comfort of the patient's face and neck treatment of patients. It can improve the quality, elasticity, and texture of the skin. RESULTS: According to the author's knowledge of oral and maxillofacial surgery, the combination of BNB and SCPB is applied to the neck and facial analgesia. Combining the BNB and SCPB effectively provides facial and neck anesthesia. The BNB in this technique provides pain relief to the facial skin in the mandibular area and SCPB offers pain relief to the skin of the neck. RF facial rejuvenation treatment often involves the junction of the face and neck to improve the contour of the mandibular margin. Therefore, Whether the RF treatment is aimed at the face or neck, or the treatment is performed simultaneously, we advocate the block both of the buccal nerve and the superficial cervical plexus nerves to achieve perfect analgesia. Still, the dosage of anesthetic medication for the nerve block can be adjusted according to the treatment area. CONCLUSION: We applied these two nerve blocks and their combination to improve skin laxity with RF therapy for the first time.

The efficacy and safety of opioid-free anesthesia combined with ultrasound-guided intermediate cervical plexus block vs. opioid-based anesthesia in thyroid surgery-a randomized controlled trial.

PURPOSE: In the context of the current comfort medicine and enhanced recovery after surgery, there is a demand for a new anesthesia method to reduce adverse reactions and accelerate recovery after surgery. This randomized controlled trial aimed to compare the efficacy and safety between opioid-free anesthesia (OFA) combined with ultrasound-guided intermediate cervical plexus block (ICPB) and opioid-based anesthesia in patients after thyroid surgery. METHODS: In this study, 75 patients scheduled for thyroid surgery under general anesthesia were randomly allocated into two groups. The primary outcome included the incidence of nausea within 24 h after surgery. The main secondary outcomes included the incidence of vomiting and the visual analog score (VAS) scores within 24 h after surgery as well as the quality of recovery 40 questionnaires (QoR-40) scores 24 h after surgery. RESULTS: In the OFA group, the incidence of postoperative nausea was 6.1%, compared to 39.4% in the control group (p = 0.001). No patient presented with postoperative vomiting in the OFA group, while 15.2% of patients suffered from postoperative vomiting in the control group (p = 0.063). The VAS scores of patients in the postanesthetic care unit (PACU) and 2 h, 4 h, and 6 h after surgery were lower in the OFA group, and the difference is statistically significant. Besides, the VAS scores of patients at rest (p = 1.000) and during swallowing (p = 1.000) 24 h after surgery were comparable. CONCLUSION: Compared with opioid-based anesthesia, the OFA combined with the ultrasound-guided ICPB can better improve patients' postoperative recovery, reduce nausea, and decrease pain scores.

Ultrasound-guided bilateral superficial cervical plexus block enhances the quality of recovery of uremia patients with secondary hyperparathyroidism following parathyroidectomy: a randomized controlled trial.

BACKGROUND: Parathyroidectomy has been proposed as a method for reducing parathyroid hormone levels. We evaluated the effects of ultrasound-guided bilateral superficial cervical plexus block (BSCPB) on the quality of recovery of uremia patients with secondary hyperparathyroidism (SHPT) following parathyroidectomy. METHODS: Eighty-two uremia patients who underwent parathyroidectomy and exhibited SHPT were randomly allocated to the BSCPB group or the control group (CON group). The patients received ultrasound-guided BSCPB with 7.5 ml of ropivacaine 0.5% on each side (BSCPB group) or equal amount of 0.9% normal saline (CON group). The primary outcome of the Quality of Recovery-40(QoR-40) score was recorded on the day before surgery and postoperative day 1(POD1). Secondary outcomes including total consumption of remifentanil, time to first required rescue analgesia, number of patients requiring rescue analgesia, and total consumption of tramadol during the first 24 h after surgery were recorded. The occurrence of postoperative nausea or vomiting (PONV) and the visual analogue scale (VAS) scores were assessed and recorded. RESULTS: The scores on the pain and emotional state dimensions of the QoR-40 and the total QoR-40 score were higher in the BSCPB group than in the CON group on POD1 (P = 0.000). Compared with the CON group, the total consumption of remifentanil was significantly decreased in the BSCPB group (P = 0.000). The BSCPB group exhibited longer time to first required rescue analgesia (P = 0.018), fewer patients requiring rescue analgesia (P = 0.000), and lower postoperative total consumption of tramadol during the first 24 h after surgery (P = 0.000) than the CON group. The incidence of PONV was significantly lower in the BSCPB group than in the CON group (P = 0.013). The VAS scores in the BSCPB group were lower than those in the CON group at all time-points after surgery (P = 0.000). CONCLUSION: Ultrasound-guided BSCPB with ropivacaine 0.5% can enhance the quality of recovery, postoperative analgesia, and reduce the incidence of PONV in uremia patients with SHPT following parathyroidectomy.

[Cervical plexus block as an alternative anesthetic approach for type I thyroplasty: a case report]. / Bloqueio do plexo cervical como técnica anestésica alternativa para tireoplastia tipo I: relato de caso.

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.

Resumo Introdução: O papel da tireoplastia tipo I (TPI) está bem estabelecido no tratamento de insuficiência glótica após a paralisia das pregas vocais, mas o manejo anestésico ideal para a TPI ainda é controverso. Descrevemos uma nova técnica anestésica para a TPI usando o Bloqueio do Plexo Cervical (BPC) superficial e o BPC intermediário associados, em presença de analgo-sedação leve e intermitente. Relato de caso: Paciente de 51 anos de idade com paralisia da prega vocal esquerda e apneia obstrutiva do sono foi agendada para TPI. BPC intermediário guiado por ultrassom foi realizado usando acesso posterior, e 15 mL de ropivacaína a 0,5% foram injetados no espaço cervical posterior entre o músculo esternocleidomastoideo e a fáscia prevertebral. A seguir, para o BPC superficial, 10 mL de ropivacaína a 0,5% foram injetados na região subcutânea adjacente à borda posterior do músculo esternocleidomastoideo, sem transfixar a fáscia de revestimento. Analgo-sedação intermitente com infusão alvo-controlada de remifentanil (alvo de 0,5 ng.mL-1) foi usada para facilitar a inserção da prótese e a laringoscopia com fibra ótica. A técnica ofereceu via aérea segura durante a anestesia, boa condição para o cirurgião, possibilidade de monitorar a voz, além de ótimo conforto à paciente. Conclusões: O uso de anestesia regional é uma técnica promissora para o cuidado anestésico durante a TPI, especialmente em pacientes com via aérea comprometida.

The effect of bupivacaine on postoperative pain following thyroidectomy: a systematic review and meta-analysis.

INTRODUCTION: Thyroid surgery, which is usually followed by moderate postoperative pain, has gained increasing attention in recent years. A systematic review and meta-analysis was conducted to assess the effect of prophylactic bupivacaine on postoperative pain following thyroidectomy. EVIDENCE ACQUISITION: We searched the PubMed, Web of Science, Embase, and Cochrane Library databases for specific keywords. RevMan 5.0 and Stata 12.0 software were used to perform meta-analyses. The endpoints were postoperative pain, rescue analgesic requirement, and postoperative nausea and vomiting (PONV) during the immediate 24 h postoperative period. EVIDENCE SYNTHESIS: A total of 18 randomized controlled trials (RCTs) with 1308 patients were included in the meta-analysis. A significant reduction of pain according to the postoperative pain scale at 1 hour (P<0.05) and rescue analgesic requirement (P<0.05) was observed following local infiltration with bupivacaine. A bilateral superficial cervical plexus block (BSCPB) with bupivacaine also significantly reduced postoperative pain at 1 hour (P<0.01) and 24 hours (P<0.01), as well as rescue analgesic requirement (P<0.00001) and PONV (P<0.01). Compared with BSCPB, local infiltration with bupivacaine provides a better effect in terms of postoperative analgesia (P<0.05). CONCLUSIONS: We recommend local infiltration with bupivacaine ranged from 20 to 75 mg before or after skin closure or BSCPB with bupivacaine ranged from 25 to 100 mg to reduce postoperative pain after thyroidectomy.

Intermediate Cervical Plexus Block in the Management of Persistent Postoperative Pain Post Carotid Endarterectomy: A Prospective, Randomized, Controlled, Clinical Trial.

BACKGROUND: The mechanisms of persistent postoperative pain (PPP) with neuropathic features after carotid endarterectomy (CEA) are multifaceted and are incompletely understood. OBJECTIVES: The aim of this research was to assess whether the ultrasound-guided (USG) intermediate cervical plexus block (ICPB) could provide better control of PPP and neuropathic disturbances (NPDs) after CEA than the USG superficial cervical plexus block (SCPB). STUDY DESIGN: Prospective, randomized, controlled, clinical trial. SETTING: This clinical trial was conducted at the SS Filippo and Nicola Academic Hospital of Avezzano (L'Aquila, Italy). METHODS: Patients who were scheduled for primary CEA were chosen. In the experimental group, the USG-ICPB was performed unilaterally, at the level of the third cervical vertebra. The needle was inserted into the deep lamina of the deep fascia of the neck, between the posterior border of the middle scalene muscle and the anterior border of the posterior scalene muscle. Three milliliters saline solution was injected into the opening of the deep lamina, and 20 mL 0.375% levobupivacaine was injected. In the control group, the anesthetic target was located at the inferior border of the sternocleidomastoid muscle at the level of the third cervical vertebra. The needle was superficially inserted below the skin, and 2 to 3 mL saline solution was injected into the opening of the superficial lamina of the deep fascia of the neck. A total of 20 mL 0.375% isobaric levobupivacaine was subsequently injected.The primary outcome measure was the proportion of patients with PPP on movement and at rest 3 months after surgery. The secondary outcome measures were NPD assessment scores using the von Frey hair test and the Lindblom test, opioid and pregabalin consumption. Adverse effects were also recorded. RESULTS: A total of 98 consecutive patients were enrolled and randomized to receive either a USG-SCPB (control group, n = 49) or a USG-ICPB (experimental group, n = 49). The sensory blockade was longer in the experimental group. Three months after surgery, the proportions of patients with PPP on movement were significantly different between the experimental and control groups (33%, 95% confidence intervals [CI], 20%-47% vs. 71%, 95% CI, 57%-83%; P < 0.001), whereas there were no differences in the proportions of patients with pain at rest between groups (31%, 95% CI, 18%-45% vs. 49%, 95% CI, 34%-64%; P = 0.063). The proportions of patients with NPDs were not different between the groups, whereas the sizes of the areas of interest (cm2) were significantly different. LIMITATIONS: A limitation of this study is that we assessed NPDs for only 3 months using the von Frey hair test and the Lindblom test without additional instrumental techniques. Additionally, there are many risk factors for NPDs after CEA. For this reason, another limitation of this research is that we neglected to consider the relationship between the choice of anesthetic block and the presence of these risk factors. CONCLUSIONS: The USG-ICPB provided long-lasting analgesia during the postoperative period and might mitigate the development of NPDs, thereby decreasing the analgesic drug requirement. KEY WORDS: Carotid endarterectomy, intermediate cervical plexus block, myofascial planes of neck, neuropathic disturbances, persistent postoperative pain, superficial cervical plexus blocks, ultrasound guidance, vascular disease.

Combined supraclavicular and superficial cervical plexus block for clavicle surgery.

BACKGROUND: Clavicle fractures occur in 35% of shoulder girdle fractures. Surgical fixation is preferred, especially in young patients for optimal functional outcomes, while nondisplaced fractures are usually treated conservatively. CASE: A 38-year-old male patient was admitted to the emergency services with a fracture of the left clavicle following a fall. During the preoperative evaluation, the patient requested to be awake during the surgery. Combined supraclavicular and superficial cervical plexus block was performed under ultrasound guidance without complications and the patient experienced no pain. CONCLUSIONS: This technique may avoid possible complications related to interscalene brachial plexus block. Future studies are required to confirm the safety and efficacy of this approach.

Effects of regional anesthesia techniques on local anesthetic plasma levels and complications in carotid surgery: a randomized controlled pilot trial.

BACKGROUND: The ultrasound guided intermediate cervical plexus block with perivascular infiltration of the internal carotid artery (PVB) is a new technique for regional anesthesia in carotid endarterectomy (CEA). We conducted a pilot study investigating the effects of deep cervical block (DCB), intermediate cervical block alone (ICB) and PVB on perioperative complications in patients undergoing elective CEA. We hypothesized, that the ropivacaine plasma concentration is higher in patients receiving DCB compared to PVB and ICB. METHODS: In a randomized controlled pilot study thirty patients scheduled for elective CEA were randomly assigned into three groups: DCB receiving 20 mL ropivacaine 0.5% (n = 10), ICB receiving 20 mL ropivacaine 0.5% (n = 10) and PVB receiving 20 mL ropivacaine 0.5% and 10 mL ropivacaine 0,3% (n = 10). As primary outcome, plasma levels of ropivacaine were measured with high performance liquid chromatography before, 5, 10, 20, 60, and 180 min after the injection of ropivacaine. Secondary outcomes were vascular and neurological complications as well as patients' and surgeons' satisfaction. All analyses were performed on an intention-to-treat basis. Statistical significance was accepted at p < 0.05. RESULTS: No conversion to general anesthesia was necessary and we observed no signs of local anesthetic intoxication or accidental vascular puncture. Plasma concentration of ropivacaine was significantly higher in the DCB group compared to PVB and ICB (p < 0.001) and in the PVB group compared to ICB (p = 0.008). Surgeons' satisfaction was higher in the PVB group compared to ICB (p = 0.003) and patients' satisfaction was higher in the PVB group compared to ICB (p = 0.010) and DCB group (p = 0.029). Phrenic nerve paralysis was observed frequently in the DCB group (p < 0.05). None of these patients with hemi-diaphragmatic paralysis showed signs of respiratory distress. CONCLUSION: The ultrasound guided PVB is a safe and effective technique for CEA which is associated with lower plasma levels of local anesthetic than the standard DCB. Considering the low rate of complications in all types of regional anesthesia for CEA, larger randomized controlled trials are warranted to assess potential side effects among the blocks. TRIAL REGISTRATION: The trial was registered at German Clinical Trials Register (DRKS) on 04/05/2019 (DRKS00016705, retrospectively registered).

[Perioperative analgesic efficacy of bilateral superficial cervical plexus block in patients undergoing thyroidectomy: a randomized controlled trial]. / Eficácia analgésica perioperatória do bloqueio bilateral do plexo cervical superficial em pacientes submetidos à tireoidectomia: estudo clínico randomizado.

INTRODUCTION: Bilateral superficial cervical plexus block (BSCPB) is a common method used for analgesia in thyroid surgery. We investigated the analgesic efficacy of bilateral superficial cervical plexus block in the intraoperative and postoperative periods. MATERIALS AND METHODS: Patients (n = 46) undergoing thyroidectomy were randomly separated into the following 2 groups: the general anesthesia group (GA; n = 23) and the general anesthesia plus BSCPB group (GS; n = 23). The intraoperative analgesic requirement (remifentanil) visual analog scale (VAS) score at multiple time points during the postoperative period (after extubation, at 15 and 30 minutes and 1, 2, 6, 12, 24 and 48 hours post operation) were evaluated. Total tramadol and paracetamol consumption as well as the amount of ondansetron used was recorded. RESULTS: The intraoperative remifentanil requirement was significantly lower in the GS Group than in the GA Group (p = 0.009). The postoperative pain scores were significantly lower in the GS Group than in the GA Group at 15 (p < 0.01) and 30 (p < 0.01) minutes and 1 (p < 0.01), 2 (p < 0.01), 6 (p < 0.01), 12 (p < 0.01) and 24 (p = 0.03) hours. The postoperative tramadol requirement was significantly lower in the GS Group than in the GA Group (p = 0.01). The number of patients that used ondansetron was significantly lower in the GS Group than in the GA Group (p = 0.004). CONCLUSION: We concluded that BSCPB with 0.25% bupivacaine reduces the postoperative pain intensity and opioid dependency in thyroid surgery patients.

Perioperative analgesic efficacy of bilateral superficial cervical plexus block in patients undergoing thyroidectomy: a randomized controlled trial / Eficácia analgésica perioperatória do bloqueio bilateral do plexo cervical superficial em pacientes submetidos à tireoidectomia: estudo clínico randomizado

Abstract Introduction: Bilateral superficial cervical plexus block (BSCPB) is a common method used for analgesia in thyroid surgery. We investigated the analgesic efficacy of bilateral superficial cervical plexus block in the intraoperative and postoperative periods. Materials and methods: Patients (n = 46) undergoing thyroidectomy were randomly separated into the following 2 groups: the general anesthesia group (GA; n = 23) and the general anesthesia plus BSCPB group (GS; n = 23). The intraoperative analgesic requirement (remifentanil) and visual analog scale (VAS) score at multiple time points during the postoperative period (after extubation, at 15 , 30 minutes and 1, 2, 6, 12, 24, and 48 hours post operation) were evaluated. Total tramadol and paracetamol consumption as well as the amount of ondansetron used was recorded. Results: The intraoperative remifentanil requirement was significantly lower in the GS Group than in the GA Group (p= 0.009). The postoperative pain scores were significantly lower in the GS Group than in the GA Group at 15 (p< 0.01), 30 (p< 0.01) minutes, and 1 (p< 0.01), 2 (p< 0.01), 6 (p< 0.01), 12 (p< 0.01) and 24 (p= 0.03) hours. The postoperative tramadol requirement was significantly lower in the GS Group than in the GA Group (p= 0.01). The number of patients that used ondansetron was significantly lower in the GS Group than in the GA Group (p= 0.004). Conclusion: We concluded that BSCPB with 0.25% bupivacaine reduces the postoperative pain intensity and opioid dependency in thyroid surgery patients.

Resumo Introdução: O bloqueio bilateral do plexo cervical superficial (BPCS) é um método comumente usado para analgesia em tireoidectomia. Avaliamos a eficácia analgésica do bloqueio bilateral do BPCS nos períodos intraoperatório e pós-operatório. Materiais e métodos: Os pacientes (n = 46) submetidos à tireoidectomia foram randomicamente separados em dois grupos para receber anestesia geral (Grupo GA; n = 23) e anestesia geral mais bloqueio bilateral do BPCS (Grupo GS; n = 23). Avaliamos a necessidade de analgésico no intraoperatório (remifentanil) e os escores VAS (Visual Analog Scale) em vários momentos no pós-operatório (após a extubação, aos 15 e 30 minutos e em 1, 2, 6, 12, 24 e 48 horas de pós-operatório). O consumo total de tramadol e paracetamol e a quantidade usada de ondansetrona foram registrados. Resultados: A necessidade de remifentanil no intraoperatório foi significativamente menor no Grupo GS do que no Grupo GA (p = 0,009). Os escores de dor pós-operatória foram significativamente menores no Grupo GS do que no grupo GA aos 15 (p < 0,01) e 30 (p < 0,01) minutos e em 1 (p < 0,01), 2 (p < 0,01), 6 (p < 0,01), 12 (p < 0,01) e 24 (p = 0,03) horas de pós-operatório. A necessidade de tramadol no pós-operatório foi significativamente menor no Grupo GS do que no grupo GA (p = 0,01). O número de pacientes que recebeu ondansetrona foi significativamente menor no Grupo GS do que no Grupo GA (p = 0,004). Conclusão: O bloqueio bilateral do BPCS com bupivacaína a 0,25% reduz a intensidade da dor pós-operatória e a dependência de opioides em pacientes submetidos à tireoidectomia.

Superficial cervical plexus blockade improves pain control after thyroidectomy: A randomized controlled trial.

OJECTIVES: The aim was to evaluate the ability of bilateral superficial cervical plexus blockade to control pain and to reduce the side effects of general anesthesia in patients submitted to thyroidectomy. METHODS: In this randomized controlled trial, we prospectively studied 100 consecutive patients who underwent total thyroidectomy. The simple random patient sample was divided into two groups: 50 patients received general anesthesia alone (group 1 [G1]), and 50 patients received general anesthesia with bilateral superficial cervical plexus blockade (group 2 [G2]). Statistical analyses were performed, and a 5% significance level was adopted. RESULTS: The mean arterial blood pressure and heart rate were 12% lower in G2 patients than in G1 patients 60 minutes after surgery (101 mmHg for G1 vs. 92.3 mmHg for G2; p<0.001). G2 patients reported less pain than G1 patients, and opioid consumption was lower in G2 patients than in G1 patients, not upon postanesthesia care unit arrival, but at 30 minutes (2% vs. 34%; p<0.001, respectively), 45 minutes (0% vs. 16%; p=0.006, respectively), and 4 hours postoperatively (6% vs. 20%; p=0.037, respectively). The incidence of nausea and vomiting was lower in G2 patients than in G1 patients from 45 minutes (0% vs. 16%; p=0.006, respectively) to 8 hours postoperatively (0% vs. 14%; p=0.012, respectively). CONCLUSIONS: The present study demonstrated that the combination of bilateral superficial cervical plexus blockade with general anesthesia for thyroidectomy is feasible, safe, and effective for achieving pain control and improving patient outcomes.
