RESUMO
INTRODUCTION/AIMS: Intercostal nerve injury can occur after rib fractures, resulting in denervation of the abdominal musculature. Loss of innervation to the rectus abdominis and intercostal muscles can cause pain, atrophy, and eventual eventration, which may be an underrecognized and thus undertreated complication of rib fractures. We investigated the clinical utility of intercostal nerve electrodiagnostic testing following rib fractures to diagnose and localize nerve injury at levels T7 and below. METHODS: Five patients with displaced bicortical rib fractures involving the 7th-11th ribs and clinical eventration of the ipsilateral abdominal wall underwent intercostal nerve conduction studies (NCS) and needle electromyography (EMG) on the affected side. EMG of the rectus abdominis and intercostal muscles was performed with ultrasound guidance, and ultrasound measurements of rectus abdominis thickness were obtained to assess for atrophy. RESULTS: Average patient age was 59.4 years and average body mass index (BMI) was 31.5 kg/m2. Intercostal NCS and EMG were able to reliably diagnose and localize intercostal nerve damage after rib fractures. Ultrasound demonstrated an average rectus abdominis transverse cross-sectional thickness of 0.534 cm on the affected side, compared with 1.024 cm on the non-affected side. DISCUSSION: Intercostal electrodiagnostic studies can diagnose and localize intercostal nerve damage after displaced rib fractures. Musculoskeletal ultrasound can be used to diagnose and quantify rectus abdominis atrophy and to accurately and safely guide needle EMG to the intercostal and rectus abdominis muscles.
RESUMO
BACKGROUND: Intercostal nerve cryoablation (INC) has shown promise as an adjunct method for analgesia in adults undergoing thoracotomy, but has yet to be widely used in children for this indication. We hypothesize that INC decreases opioid utilization in children undergoing thoracotomy for cancer operations. METHODS: A retrospective review was performed of children who underwent thoracotomy for cancer diagnosis at a freestanding children's hospital from 2018 to 2023. Patient characteristics, intraoperative data, and data on clinical course were collected. Patients were divided into those who underwent INC and those who underwent routine care for comparison. RESULTS: Twenty-six patients underwent 38 procedures at a median age of 16 years (range 5-21 years). INC was performed in 23 cases over a median of five intercostal levels (range 2-7). Total oral morphine equivalents during inpatient admission were significantly lower in INC patients (137.6 vs. 514.5 mg, p = .002). Routine care patients were more likely to be discharged with an opioid prescription (30.4% vs. 80.0%, p = .008). Length of stay was similar between patients with INC and routine care (4 vs. 5 days, p = .15). There were no differences in rates of reoperation or 30-day re-admission (emergency department or inpatient). CONCLUSTIONS: INC is a feasible and safe adjunct for children undergoing thoracotomy for cancer. INC is associated with reduced postoperative opioid utilization with respect to both inpatient use and outpatient prescriptions.

We read the recently published article "Effect of Ropivacaine Intercostal Nerve Block Combined with Patient Controlled Intravenous Analgesia on Postoperative Analgesia after Breast Augmentation" by You et al. We have noticed several issues in the methods and results of this study and would appreciate the responses from the authors. We question several aspects, opioid-sparing effect, sufentanil consumption, sample size evaluation, exclusion reasons, and side effects.
RESUMO
INTRODUCTION: Autologous costal cartilage harvest is a common procedure in craniofacial reconstruction due to its stability, dependability, and diversity. However, such a procedure is associated with severe donor-site pain postoperatively. Therefore, we aim through this study to compare the efficacy of intercostal nerve block in the management of postoperative pain in patients undergoing costal cartilage harvest for craniofacial reconstruction. METHOD: This systematic review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The study systematically reviewed MEDLINE, Cochrane, and EMBASE databases without time-limitation. RESULTS: As a result of reviewing the literature, 33 articles were screened by full-text resulting in 14 articles which met our inclusion/exclusion criteria. However, only four high-quality RCT articles were included in the quantitative synthesis (meta-analysis). The findings of this study suggest that there is no significant difference in pain scores between ICNB and control groups at 12, 24, and 48 h postoperatively, both at rest and with coughing. Therefore, both techniques are considered safe and effective. CONCLUSION: Our results show evidence of favorable outcome of preventive donor-site analgesia with ICNB for harvesting autologous costal cartilage in multiple studies. However, the overall outcomes were insignificant between the two arms.

BACKGROUNDS: To observe the effect of ropivacaine intercostal nerve block combined with PCIA as early postoperative analgesia following breast augmentation surgery with prosthesis (axillary approach) METHODS: A total of 80 women with breast augmentation surgery were selected in the plastic surgery department of Chongqing Huamei Plastic Surgery Hospital from December 2021 to May 2022. They were equally randomized into control group and observation group, with 40 cases in each one. Before placing the prosthesis, the control group was given 0.9% normal saline for intercostal nerve block; the observation group was given 0.75% ropivacaine + 1 adrenaline for intercostal nerve block. Patient controlled intravenous analgesia (PCIA) was used after operation. Observation indexes the visual analog scale (VAS) of resting and motor state at 4 h, 24 h, 48 h and 72 h after operation and the adverse reactions. RESULTS: The VAS scores of patients at rest and exercise and adverse reactions in the observation group were lower than those in the control group (P<0.05). CONCLUSION: Ropivacaine intercostal nerve block combined with PCIA can effectively alleviate the pain after breast augmentation with pectoralis major prosthesis through axillary incision, help patients more comfortably through the perioperative period, accelerate postoperative recovery, reduce the dosage of systemic opioids and effectively reduce side effects.

RESUMO
PURPOSE OF REVIEW: The purpose of this review is to provide an up-to-date description and overview of the rapidly growing literature pertaining to techniques and clinical applications of chest wall and abdominal fascial plane blocks in managing perioperative pain. RECENT FINDINGS: Clinical evidence suggests that regional anesthesia blocks, including fascial plane blocks, such as pectoralis, serratus, erector spinae, transversus abdominis, and quadratus lumborum blocks, are effective in providing analgesia for various surgical procedures and have more desirable side effect profile when compared to traditional neuraxial techniques. They offer advantages such as reduced opioid consumption, improved pain control, and decreased opioid-related side effects. Further research is needed to establish optimal techniques and indications for these blocks. Presently, they are a vital instrument in a gamut of multimodal analgesia options, especially when there are contraindications to neuraxial or para-neuraxial procedures. Ultimately, clinical judgment and provider skill set determine which blocks-alone or in combination-should be offered to any patient.

PURPOSE: The objective of this study was to report the functional outcomes and factors affecting the result of intercostal nerves transfer to the radial nerve branch to the long head triceps muscle for restoration of elbow extension in patients with total brachial plexus palsy or C5 to C7 palsy with the loss of triceps muscle function. METHODS: Fifty-five patients with total brachial plexus palsy or C5 to C7 palsy with no triceps muscle function had a reconstruction of elbow extension by transferring the third to fifth intercostal nerves to the radial nerve branch to the long head triceps muscle. The functional outcomes determined by the Medical Research Council grading were evaluated. Factors influencing the outcomes were determined using logistic regression analysis. RESULTS: At the follow-up of at least 2 years, 36 patients (65%) had antigravity motor function (Medical Research Council grade, ≥3). Multivariable logistic regression analysis showed that the body mass index, time to surgery, and injury of the dominant limb were associated with the outcome. CONCLUSIONS: The third to fifth intercostal nerves transfer to the radial nerve branch to the long head triceps muscle is an effective procedure to restore elbow extension. We would recommend using 3 intercostal nerves without grafts; in cases of nerve root avulsion in which there is no chance of spontaneous recovery, early surgery should be considered. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

BACKGROUND: The efficacy of thoracoscopic intercostal nerve blocks (TINBs) for noxious stimulation from video-assisted thoracic surgery (VATS) remains unclear. The efficacy of TINBs may also be different between nonintubated VATS (NIVATS) and intubated VATS (IVATS). We aim to compare the efficacy of TINBs on analgesia and sedation for NIVATS and IVATs intraoperatively. METHODS: Sixty patients randomized to the NIVATS or IVATS group (30 each) received target-controlled propofol and remifentanil infusions, with bispectral index (BIS) maintained at 40-60, and multilevel (T3-T8) TINBs before surgical manipulations. Intraoperative monitoring data, including pulse oximetry, mean arterial pressure (MAP), heart rate, BIS, density spectral arrays (DSAs), and propofol and remifentanil effect-site concentration (Ce) at different time points. A two way ANOVA with post hoc analysis was applied to analyze the differences and interactions of groups and time points. RESULTS: In both groups, DSA monitoring revealed burst suppression and α dropout immediately after the TINBs. The Ce of the propofol infusion had to be reduced within 5 min post-TINBs in both NIVATS (p < 0.001) and IVATS (p = 0.252) groups. The Ce of remifentanil infusion was significantly reduced after TINBs in both groups (p < 0.001), and was significantly lower in NIVATS (p < 0.001) without group interactions. CONCLUSION: The surgeon-performed intraoperative multilevel TINBs allow reduced anesthetic and analgesic requirement for VATS. With lower requirement of remifentanil infusion, NIVATS presents a significantly higher risk of hypotension after TINBs. DSA is beneficial for providing real-time data that facilitate the preemptive management, especially for NIVATS.

PURPOSE: This study investigated whether the divided method of multi-level intercostal nerve block (ML-ICB) could reduce the ropivacaine dose required during thoracoscopic pulmonary resection, while maintaining the resting postoperative pain scores. METHODS: This retrospective, single-cohort study enrolled 241 patients who underwent thoracoscopic pulmonary resection for malignant tumors between October 2020 and March 2022 at a cancer hospital in Japan. ML-ICB was performed by surgeons under direct vision. The differences in intraoperative anesthetic use and postoperative pain-related variables at the beginning and end of surgery between group A (single-shot ML-ICB; 0.75% ropivacaine, 20 mL at the end of the surgery) and group B (divided ML-ICB, performed at the beginning and end of surgery; 0.25% ropivacaine, 30 mL total) were assessed. The numerical rating scale (NRS) was used to evaluate pain 1 h and 24 h postoperatively. RESULTS: Intraoperative remifentanil use was significantly lower in group B (14.4 ± 6.4 µg/kg/h) than in group A (16.7 ± 8.4 µg/kg/h) (P = 0.02). The proportion of patients with NRS scores of 0 to 3 at 24 h was significantly higher in group B (85.4%, 106/124) than in group A (73.5%, 86/117) (P = 0.02). The proportion of patients not requiring postoperative intravenous rescue drugs was significantly higher in group B (78.2%, 97/124) than in group A (61.5%, 72/117) (P < 0.01). CONCLUSION: The divided method of ML-ICB could reduce the intraoperative remifentanil dose, decrease the postoperative pain score at 24 h, and curtail postoperative intravenous rescue drug use, despite using half the total ropivacaine dose intraoperatively.

BACKGROUND: Minimally invasive direct coronary artery bypass (MIDCAB) grafting surgery is accompanied by severe pain. Although continuous intercostal nerve block (CINB) has become one of the multimodal analgesic techniques in single port thoracoscopic surgery, its effects on MIDCAB are unclear. The purpose of this study was to compare the effects of CINB and single shot on analgesic outcomes and hospital stays in patients undergoing MIDCAB in a real-world setting. METHODS: A retrospective cohort study was carried out at Peking University Third Hospital, China. Two hundred and sixteen patients undergoing MIDCAB were divided into two groups: a CINB group and a single block (SI) group. The primary outcome was postoperative maximal visual analog scale (VAS); secondary outcomes included the number of patients with maximal VAS ≤ 3, the demand for and consumed doses of pethidine and tramadol, and the length of intensive care unit (ICU) and hospital stays. The above data and the area under the VAS curve in the 70 h after extubation for the two subgroups (No. of grafts = 1) were also compared. RESULTS: The maximum VAS was lower in the CINB group, and there were more cases with maximum VAS ≤ 3 in the CINB group: CINB 52 (40%) vs. SI 17 (20%), P = 0.002. The percentage of cases requiring tramadol and pethidine was less in CINB, P = 0.001. Among all patients, drug doses were significantly lower in the CINB group [tramadol: CINB 0 (0-100) mg vs. SI 100 (0-225) mg, P = 0.0001; pethidine: CINB 0 (0-25) mg vs. SI 25 (0-50) mg, P = 0.0004]. Further subgroup analysis showed that the area under the VAS curve in CINB was smaller: 28.05 in CINB vs. 30.41 in SI, P = 0.002. Finally, the length of ICU stay was shorter in CINB than in SI: 20.5 (11.3-26.0) h vs. 22.0 (19.0-45.0) h, P = 0.011. CONCLUSIONS: CINB is associated with decreased demand for rescue analgesics and shorter length of ICU stay when compared to single shot intercostal nerve block. Additional randomized controlled trial (RCT) is needed to support these findings.

BACKGROUND: The objective of this study was to compare analgesic efficacy of erector spinae plane block(ESPB) and thoracic paravertebral block(TPVB) combined with intercostal nerve block(ICNB) after video assisted thoracoscopic surgery(VATS). METHODS: Patients were enrolled into three groups according to analgesia technique as ICNB, TPVB + ICNB or ESPB + ICNB: respectively Group C(n = 58), Group T (n = 56) and Group E (n = 59). Patients were followed up by a trained data investigator at 2, 6, 8, 12, 24, 48 h after surgery, and the visual analog scale(VAS) at rest and coughing were recorded. The moderate and severe pain mean VAS ≥ 4 when coughing. The postoperative opioids consumption, incidence of postoperative nausea and vomiting (PONV), supplementary analgesic requirements within 48 h, length of stay in PACU, ambulation time, postoperative days in hospital and potential side effects, such as hematoma, hypotension, bradycardia, hypersomnia, uroschesis, pruritus and apnea were recorded. RESULTS: The incidence of moderate-to-severe pain was no significant difference between 3 groups in 24 h and 48 h (P = 0.720). There was no significant difference among the 3 groups in the resting pain intensity at 2, 6, 8, 12, 24 and 48 h after surgery(P > 0.05). In 2-way analysis of variance, the VAS when coughing in Group T were lower than that in Group C (mean difference = 0.15, 95%CI, 0.02 to 0.29; p = 0.028). While no difference was found when comparing Group E with Group C or Group T(P > 0.05). There was no difference between the three groups in the sufentanil consumption( within 24 h p = 0.472, within 48 h p = 0.158) and supplementary analgesic requirements(p = 0.910). The incidence of PONV and the length of stay in PACU, ambulation time and postoperative days in hospital were comparable in the 3 groups(P > 0.05). Two patients from Group T developed hematoma at the site of puncture. CONCLUSIONS: The present randomized trial showed that the analgesic effect of TPVB + ICNB was superior to that of INCB after VATS, the analgesic effect of ESPB was equivalent to that of TPVB and ICNB.

BACKGROUND: Adequate pain control after video-assisted thoracoscopic surgery (VATS) for lung resection is important to improve postoperative mobilisation, recovery, and to prevent pulmonary complications. So far, no consensus exists on optimal postoperative pain management after VATS anatomic lung resection. Thoracic epidural analgesia (TEA) is the reference standard for postoperative pain management following VATS. Although the analgesic effect of TEA is clear, it is associated with patient immobilisation, bladder dysfunction and hypotension which may result in delayed recovery and longer hospitalisation. These disadvantages of TEA initiated the development of unilateral regional techniques for pain management. The most frequently used techniques are continuous paravertebral block (PVB) and single-shot intercostal nerve block (ICNB). We hypothesize that using either PVB or ICNB is non-inferior to TEA regarding postoperative pain and superior regarding quality of recovery (QoR). Signifying faster postoperative mobilisation, reduced morbidity and shorter hospitalisation, these techniques may therefore reduce health care costs and improve patient satisfaction. METHODS: This multi-centre randomised study is a three-arm clinical trial comparing PVB, ICNB and TEA in a 1:1:1 ratio for pain (non-inferiority) and QoR (superiority) in 450 adult patients undergoing VATS anatomic lung resection. Patients will not be eligible for inclusion in case of contraindications for TEA, PVB or ICNB, chronic opioid use or if the lung surgeon estimates a high probability that the operation will be performed by thoracotomy. PRIMARY OUTCOMES: (1) the proportion of pain scores ≥ 4 as assessed by the numerical rating scale (NRS) measured during postoperative days (POD) 0-2; and (2) the QoR measured with the QoR-15 questionnaire on POD 1 and 2. Secondary outcome measures are cumulative use of opioids and analgesics, postoperative complications, hospitalisation, patient satisfaction and degree of mobility. DISCUSSION: The results of this trial will impact international guidelines with respect to perioperative care optimization after anatomic lung resection performed through VATS, and will determine the most cost-effective pain strategy and may reduce variability in postoperative pain management. Trial registration The trial is registered at the Netherlands Trial Register (NTR) on February 1st, 2021 (NL9243). The NTR is no longer available since June 24th, 2022 and therefore a revised protocol has been registered at ClinicalTrials.gov on August 5th, 2022 (NCT05491239). PROTOCOL VERSION: version 3 (date 06-05-2022), ethical approval through an amendment (see ethical proof in the Study protocol proof).

BACKGROUND: Pain associated with chest wall trauma is a major issue in the emergency department (ED). However, it may be challenging to select among the various analgesic procedures. OBJECTIVE: Our aim was to compare single-shot erector spinae plane block (ESPB) with intercostal nerve block (ICNB) under ultrasound guidance for pain management in thoracic trauma. METHODS: This study was a randomized nonblinded clinical trial performed in a level I urban trauma center. A convenience sample of patients with isolated chest wall trauma and initial Numeric Rating Scale pain scores (NRS 0) > 5 were included. Exclusion criteria were large pain area, surgical interventions, discharged from the ED, and presence of contraindications to lidocaine. Pain scores at 20 min and 60 min (NRS 20 and 60) and at disposition (disp) were recorded. RESULTS: Twenty-seven patients in the ESPB and 23 in the ICNB groups were enrolled. Mean values of NRS 0, 20, 60, and disp for the ESPB vs. ICNB groups were 8.0 vs. 7.4, 5.2 vs. 6.1, 4.1 vs. 5.4, and 4.3 vs. 5.8, respectively (p = 0.07, pâ¯=â¯0.04, pâ¯=â¯0.001, and p < 0.001, respectively). Four patients in the ESPB and 8 patients in the ICNB groups required administration of adjunctive doses of fentanyl for satisfactory pain control (pâ¯=â¯0.09). CONCLUSIONS: Ultrasound-guided ESPB was superior to ICNB regarding pain control during the ED stay period of patients with painful chest wall trauma. We recommend ESPB in the ED for pain control in blunt or penetrating thoracic trauma.

OBJECTIVES: Autologous costal cartilage is commonly used as a graft material in plastic surgery. However, after autologous costal cartilage removal, the pain at the surgical site is particularly strong. We conducted this controlled clinical study to verify the efficacy of methylene blue (MB) in intercostal nerve block after autologous costal cartilage removal and to provide a reference for the application of MB in postoperative analgesia after autologous costal cartilage removal. METHODS: In this study, 90 adolescent patients with congenital microtia who underwent autologous rib cartilage graft for auricular reconstruction were randomly allocated to one of three groups (Group A: intercostal nerve block was performed with 0.75% ropivacaine; Group B: intercostal nerve block was performed with 1% MB; and Group C: intercostal nerve block was performed with 1% MB and 0.75% ropivacaine mixture). Two trained researchers observed and recorded the pain status of the children at 6 hours (T1), 24 hours (T2), 48 hours (T3), and 72 hours (T4) after surgery, respectively. Numerical rating pain scale (NRS) was used for scoring. And adverse reactions such as nausea, vomiting, and skin itching were recorded. RESULTS: In this study, there was no statistical difference in age and gender of patients in Groups A, B, and C (P >0.05). In terms of NRS comparison, 6 hours after operation (T1), Group B > Group A > Group C (P< 0.05); 24 hours after operation (T2), Group B > Group A > Group C (P< 0.05); 48 hours after operation (T3), Group B > Group A > Group C (P< 0.05); 72 hours after operation (T4), Group A > Group B > Group C (P< 0.05). There were no statistically significant differences in postoperative nausea, vomiting, and skin itching among the three groups (P>0.05). CONCLUSION: The analgesic effect of IV self-controlled analgesia combined with ropivacaine is quick, but the maintenance time is short. The analgesic effect of IV self-controlled analgesia combined with MB is slow to onset but long to maintain. The analgesic effect of IV self-controlled analgesia combined with MB and ropivacaine mixture is quick and maintained for a long time. Therefore, in patients after removal of costal cartilage, we recommend the analgesic treatment method of IV self-controlled analgesia combined with MB and ropivacaine mixture.

The intercostobrachial nerve (ICBN) is commonly defined as a purely sensory nerve supplying the skin of the lateral chest wall, axilla, and medial arm. However, numerous branching patterns and distributions, including motor, have been reported. This report describes an uncommon variant of the right ICBN observed in both an 86-year-old white female cadaver and a 77-year-old white male cadaver. In both cases the ICBN presented with an additional muscular branch, termed the "medial pectoral branch", piercing and therefore innervating the pectoralis major and minor muscles. Clinically, the ICBN is relevant during surgical access to the axilla and can result in sensory deficits (persistent pain/loss of sensory function) to this region following injury. However, damage to the variation observed in these cadavers may result in additional partial motor loss to pectoralis major and minor.

Background: Uniportal thoracoscopic surgery has become widely accepted for its favourable outcomes with regard to pain. However, post-operative pain is still a concern associated with thoracic surgery. The objective of this study was to evaluate the post-operative pain of patients undergoing uniportal video-assisted thoracoscopic surgery (VATS) lobectomies using an intra-operative intercostal nerve block. Methods: All consecutive patients undergoing uniportal VATS lobectomies between October 2018 and October 2019 were reviewed retrospectively. Twenty consecutive patients in Group A underwent uniportal VATS lobectomies without intra-operative intercostal nerve blocks. The other 20 consecutive patients in Group B underwent uniportal VATS lobectomies with intra-operative intercostal nerve blocks. Numeric Pain Rating Scale (NRS) scores were recorded at 1, 12 and 24 h postoperatively. The number of anti-inflammatory drugs (non-steroidal anti-inflammatory drug [NSAIDs]) consumed until the time of chest tube removal was also recorded. Results: There was no difference between the groups with regard to sex, age, chest tube duration, length of stay, operative time or laterality. There was a significant difference in post-operative NRS scores at 1 h (P < 0.001) and 12 h (P = 0.014) between the groups. The NSAID consumption was significantly lower in Group B than in Group A (P = 0.038). Conclusion: Intra-operative intercostal nerve blocks with bupivacaine provided immediate post-operative pain relief and reduced post-operative opioid consumption in patients who underwent uniportal VATS lobectomies.
RESUMO
BACKGROUND: Postherpetic neuralgia (PHN) is common in elderly patients and can be alleviated by pulsed radiofrequency (PRF). However, PRF treatments display different efficacy on different nerves. The purpose of this study was to evaluate the efficacy and safety of ultrasound-guided PRF modulation on thoracic dorsal root ganglion (DRG) or intercostal nerve (ICN) for PHN in aged patients and to provide a theoretical basis for clinical treatment. METHODS: We classified aged patients into two groups, DRG group and ICN group, based on the needle tip position. Visual analogue scale (VAS) and concise health status questionnaire (Short-form 36 health/survey questionnaire, SF-36) were used to evaluate the pain intensity and the life quality of the patients before and 2, 4 and 12 weeks after the PRF treatments. We also recorded the adverse reactions during the treatments. RESULTS: After the PRF treatment, the scores of VAS and SF-36 (assessing general health perception, social function, emotional role, mental health, and pain) improved significantly in both groups (P < 0.05). The mean VAS score in the DRG group was significantly lower than that in the ICN group 2 weeks after treatment, and remained for 12 weeks. The SF-36 scores in the DRG group were significantly higher than those in the ICN group (P < 0.05). We found a similar incidence of adverse reactions between the two groups (P > 0.05). CONCLUSIONS: PRF therapy is safe and effective for elderly patients with postherpetic neuralgia. However, PRF treatment in dorsal root ganglion is superior to that in intercostal nerve with improving VAS and SF-36 scores to a greater extent in older patients.

PURPOSE OF REVIEW: Intercostal nerve blocks are indicated for multiple chronic pain and acute pain conditions including rib fractures, herpes zoster, post-thoracotomy pain syndrome, and intercostal neuralgia. Intercostal neuralgia is a type of neuropathic pain that is in the distribution of intercostal nerves. The purpose of this review is to evaluate the different techniques used to perform intercostal nerve blocks and review their efficacy and safety including blind technique using anatomical landmarks, and fluoroscopically guided and ultrasound-guided intercostal nerve blocks. RECENT FINDINGS: Literature search was performed with the keywords including intercostal neuralgia, treatment, intercostal nerve blocks, and radiofrequency ablation on PubMed and Google Scholar. Three studies and one case report were identified. Literature review revealed that ultrasound-guided techniques and fluoroscopically guided techniques are superior to landmark-based technique in terms of efficacy. There was no difference in efficacy and complication rates between ultrasound and fluoroscopic guidance. Ultrasound-guided techniques and fluoroscopically guided techniques can both be performed safely and effectively for various chronic pain conditions. Ultrasound guidance has its advantages of direct visualization of nerves, vessels, muscles, and the lung. It is potentially a superior technique in terms of improving accuracy and decreasing complications. Further large population randomized control studies should be conducted to compare the efficacy of intercostal nerve blocks performed under ultrasound and fluoroscopy.

BACKGROUND: Ultrasound-guided parasternal intercostal nerve block is rarely used for postoperative analgesia, and its value remains unclear. This study aimed to evaluate the effectiveness of ultrasound-guided parasternal intercostal nerve block for postoperative analgesia in patients undergoing median sternotomy for mediastinal mass resection. METHODS: This randomized, double-blind, placebo-controlled trial performed in Renmin Hospital, Wuhan University, enrolled 41 participants aged 18-65 years. The patients scheduled for mediastinal mass resection by median sternotomy were randomly assigned were randomized into 2 groups, and preoperatively administered 2 injections of ropivacaine (PSI) and saline (control) groups, respectively, in the 3rd and 5th parasternal intercostal spaces with ultrasound-guided (USG) bilateral parasternal intercostal nerve block. Sufentanil via patient-controlled intravenous analgesia (PCIA) was administered to all participants postoperatively. Pain score, total sufentanil consumption, and postoperative adverse events were recorded within the first 24 h. RESULTS: There were 20 and 21 patients in the PSI and control group, respectively. The PSI group required 20% less PCIA-sufentanil compared with the control group (54.05 ± 11.14 µg vs. 67.67 ± 8.92 µg, P < 0.001). In addition, pain numerical rating scale (NRS) scores were significantly lower in the PSI group compared with control patients, both at rest and upon coughing within 24 postoperative hours. Postoperative adverse events were generally reduced in the PSI group compared with controls. CONCLUSIONS: USG bilateral parasternal intercostal nerve block effectively reduces postoperative pain and adjuvant analgesic requirement, with good patient satisfaction, therefore constituting a good option for mediastinal mass resection by median sternotomy.

OBJECTIVE: Assess the efficacy of adding liposomal bupivacaine (LB) to bupivacaine-containing intercostal nerve blocks (ICNBs) to improve analgesia and decrease opioid consumption and hospital length of stay compared with bupivacaine-only ICNBs. DESIGN: This retrospective, observational investigation compared pain intensity scores and cumulative opioid consumption within the first 72 postoperative hours in patients who received ICNBs with bupivacaine plus LB (LB group) versus bupivacaine only (control group) after minimally invasive anatomic pulmonary resection. LB was tested for noninferiority on pain scores and opioid consumption. If LB was noninferior, superiority of LB was tested on both outcomes. SETTING: Academic tertiary care medical center. PARTICIPANTS: Adult patients undergoing minimally invasive anatomic pulmonary resection. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: For the secondary analysis, hospital length of stay was compared through the Cox regression model. Of 396 patients, 178 (45%) received LB and 218 (55%) did not. The mean (standard deviation) pain score was three (one) in the LB group and three (one) in the control group, with a difference of -0.10 (97.5% confidence interval [-0.39 to 0.18]; pâ¯=â¯0.41). The mean (standard deviation) cumulative opioid consumption (intravenous morphine equivalents) was 198 (208) mg in the LB group and 195 (162) mg in the control group. Treatment effect in opioid consumption was estimated at a ratio of geometric mean of 0.94 (97.5% confidence interval [0.74-1.20]; pâ¯=â¯0.56). Pain control and opioid consumption were noninferior with LB but not superior. Hospital discharge was not different between groups. CONCLUSIONS: LB with bupivacaine in ICNBs did not demonstrate superior postoperative analgesia or affect the rate of hospital discharge.
