Ultrasound-Guided Thoracic Paravertebral Nerve Block on Postoperative Pain, Quality of Life, and Recovery in Patients with Non-Small-Cell Lung Cancer

Comparison of Thoracoscopy-Guided Thoracic Paravertebral Block and Ultrasound-Guided Thoracic Paravertebral Block in Postoperative Analgesia of Thoracoscopic Lung Cancer Radical Surgery: A Randomized Controlled Trial

INTRODUCTION

Ultrasound-guided thoracic paravertebral block (UTPB) is widely used for postoperative analgesia in thoracic surgery. However, it has many disadvantages. Thoracoscopy-guided thoracic paravertebral block (TTPB) is a new technique for thoracic paravertebral block (TPB). In this study, we compared the use of TTPB and UTPB for pain management after thoracoscopic radical surgery for lung cancer.

METHODS

In total, 80 patients were randomly divided 1:1 into the UTPB group and the TTPB group. The surgical time of TPB, the success rate of the first puncture, block segment range, visual analog scale (VAS) scores at 2, 6, 12, 24, and 48 h post operation, and the incidence of postoperative adverse reactions were compared between the two groups.

RESULTS

The surgical time of TPB was significantly shorter in the TTPB group than in the UTPB group (2.2 ± 0.3 vs. 5.7 ± 1.7 min, t = - 12.411, P < 0.001). The success rate of the first puncture and the sensory block segment were significantly higher in the TTPB group than in the UTPB group (100% vs. 76.9%, χ2 = 8.309, P < 0.001; 6.5 ± 1.2 vs. 5.1 ± 1.3 levels, t = - 5.306, P < 0.001, respectively). The VAS scores were significantly higher during rest and coughing at 48 h post operation than at 2, 6, 12, and 24 h post operation in the TTPB group. The VAS scores were significantly lower during rest and coughing at 12 and 24 h post operation in the TTPB group than in the UTPB group (rest: 2.5 ± 0.4 vs. 3.4 ± 0.6, t = 7.325, P < 0.001; 2.5 ± 0.5 vs. 3.5 ± 0.6, t = 7.885, P < 0.001; coughing: 3.4 ± 0.6 vs. 4.2 ± 0.7, t = 5.057, P < 0.001; 3.4 ± 0.6 vs. 4.2 ± 0.8, t = 4.625, P < 0.001, respectively). No significant difference was observed in terms of postoperative adverse reactions between the two groups.

CONCLUSIONS

Compared with UTPB, TTPB shows advantages, such as simpler and more convenient surgery, shorter surgical time, a higher success rate of the first puncture, wider block segments, and superior analgesic effect. TTPB can effectively reduce postoperative pain due to thoracoscopic lung cancer radical surgery.

Optimizing patient outcomes: the impact of multimodal preemptive analgesia in video-assisted thoracoscopic lobectomy

OBJECTIVES

The aim of this study was to evaluate the efficacy of a multimodal preemptive analgesia management approach, specifically incorporating ultrasound-guided thoracic paravertebral block (UG-TPVB) in conjunction with intravenous analgesia, after video-assisted thoracoscopic (VATS) lobectomy under the guidance of enhanced recovery after surgery.

METHODS

A total of 690 patients who underwent VATS lobectomy between October 2021 and March 2022 were divided into the UG-TPVB group (group T, n = 345) and the control group (group C, n = 345). Patients in group T received UG-TPVB prior to the induction of general anaesthesia, while group C did not undergo nerve block. A comparison was conducted between the 2 groups regarding various indicators, including postoperative sedation, static/dynamic numeric rating scale scores, intraoperative fentanyl consumption, duration of mechanical ventilation/anaesthesia recovery/hospitalization, postoperative complications and other relevant factors.

RESULTS

The static/dynamic numeric rating scale scores of group T were lower than those of group C after surgery. Intraoperative fentanyl consumption in group T (0.384 ± 0.095 mg) was lower than that in group C (0.465 ± 0.053 mg). The duration of mechanical ventilation, anaesthesia recovery and hospitalization were significantly shorter in group T compared to group C. Patient satisfaction rate in group T (70.1%) was higher than that in group C (53.6%). All differences were statistically significant (P < 0.05).

CONCLUSIONS

The multimodal preemptive analgesia management strategy effectively reduces postoperative pain, decreases opioid consumption and promotes faster recovery in patients undergoing VATS lobectomy.

Effect of regional block technique on postoperative high-grade complications according to Clavien-Dindo classification in elderly patients with thoracic and abdominal cancer: a retrospective propensity score matching analysis

Background

Postoperative complications have an influence on postoperative rehabilitation, length of hospital stay and hospitalization expenses in elderly patients, especially those with higher Clavien-Dindo (C-D) classification. Patients with cancers often experience more serious postoperative complications after surgery. Different anesthesia methods can affect the postoperative outcomes of cancer patients. Regional block techniques have been recommended in guidelines for enhanced recovery after surgery. However, the relationship between regional blocks and high-grade postoperative complications remains unclear, thus, the study explored the relationship between regional block techniques and high-grade postoperative complications graded by C-D classification in elderly patients with thoracic and abdominal cancer.

Method

Retrospective enrollment of eligible elderly patients admitted to Peking University People's Hospital between January 2018 and March 2022 was conducted. Propensity score matching (PSM) and univariate and multivariate regression analyses were used to analyze the potential benefits of regional blocks for elderly patients in real world practice.

Results

A total of 2769 patients were enrolled in this study, including 568 who underwent colorectal resection, 2201 who underwent video-assisted thoracoscopic pneumonectomy. Among them, 2033 patients received regional block, while 736 patients did not. Statistical analysis indicated that regional blocks could reduce the incidence of postoperative complications of C-D classification Grade II or higher, with an Odds ratio (OR) of 0.742, 95% Confidence interval (CI) (0.552 to 0.996) (P = 0.047).

Conclusion

Regional block is associated with a reduction in the occurrence of postoperative complications graded by C-D classification in elderly patients with thoracic and abdominal cancer. The application of regional blocks can lower the risk of high-risk complications and mortality.

Effect of ultrasound-guided thoracic paravertebral block on perioperative analgesia in elderly patients undergoing video-assisted thoracic lobectomy in China: An interventional clinical randomized controlled trial

BACKGROUND

The aim of this study was to investigate the analgesic effect and safety of ultrasound-guided thoracic paravertebral block (UG-TPVB) in Chinese elderly patients undergoing video-assisted thoracic lobectomy (VATL) and to study the influence of aging factors on these effects.

METHODS

This study was a single-center, single-blind, prospective, randomized, controlled trial. A total of 300 patients scheduled for VATL were recruited and randomly divided into the UG-TPVB group (T group) and conventional anesthesia group (C group) according to the recruitment order, and subgroups were set up according to whether the age was ≥65 years old or not. The postoperative 12, 24, and 48 h static/dynamic visual analog scale (VAS) scores, intraoperative fentanyl consumption, postoperative extubation time, post-anesthesia care unit (PACU) stay time, hospitalization days, postoperative complications, and other indicators were compared between the two groups.

RESULTS

The postoperative 12, 24, and 48 h static/dynamic VAS scores of the T group were significantly lower than those of the C group. The intraoperative fentanyl consumption, postoperative extubation time, PACU stay time, and postoperative hospitalization days were significantly lower than those of the C group. The incidence of postoperative 48 h urinary retention in the T group was significantly lower than that in the C group. These advantages showed no significant difference or slight difference between elderly patients and nonelderly patients, indicating that UG-TPVB did not influence the analgesic effect and safety of VATL patients by age or age difference.

CONCLUSION

UG-TPVB is an effective and safe perioperative analgesia method for elderly VATL patients. Its application improves the quality of life and prognosis of elderly VATL patients.

Can Ultrasound-Guided Continuous Paravertebral Block Reduce the Incidence of Chronic Postsurgical Pain in Patients with Thoracoscopic Lung Cancer Surgery? A Randomized Controlled Trial

Background

Thoracoscopic lung cancer surgery is accompanied by severe pain. Both continuous paravertebral block (CPVB) and continuous wound infiltration (CWI) are widely used for perioperative analgesia in thoracoscopic surgery. However, the effects of these different methods on chronic postsurgical pain (CPSP) are still unknown. Patients and Methods. This prospective randomized controlled trial assessed the eligibility of 113 patients. Ninety-seven patients who met the inclusion criteria were randomly divided into a CPVB group and a CWI group, and 80 patients were analyzed in the final study. The primary outcome measures were the incidence and intensity of chronic postsurgical pain (CPSP) at 3, 6, and 9 months after surgery. The secondary outcome measures were the numerical rating scale (NRS) score of rest and activity at 12, 18, and 24 hours and on the 2nd, 3rd, and 7th days postoperatively; the Barthel Activities of Daily Living (ADL) score of activity levels on the 1st, 2nd, 3rd, and 7th days postoperatively; and the long-term quality of the life score at 3, 6, and 9 months postoperatively.

Results

The incidence of chronic postsurgical pain in the CWI group was significantly higher than that in the CPVB group at 3, 6, and 9 months after surgery (all P < 0.05). The intensity of chronic postsurgical pain was significantly decreased in the CPVB group at 3, 6, and 9 months after surgery (P < 0.05). NRS-R and NRS-A scores were significantly decreased in the CPVB group within the first week after thoracoscopic surgery (P < 0.001). ADL scores were increased in the CPVB group within 3 days postoperatively. However, there were no differences in the ADL score on the 7th postoperative day or the long-term quality of the life score at 3, 6, and 9 months postoperatively.

Conclusion

Continuous ultrasound-guided paravertebral block reduced the intensity of acute pain within 7 days postoperatively and reduced the incidence of chronic pain at 3, 6, and 9 months after surgery, but there was no significant advantage in long-term quality of life. This trial is registered with ChiCTR2000038505.

Interventional Treatment Options for Post-mastectomy Pain

PURPOSE OF REVIEW

Breast cancer is currently the most prevalent cancer diagnosed globally, and there is a significant gap in the availability of effective first-line treatment options. In addition to a cancer diagnosis, breast cancer patients face additional pain and morbidity after treatment. Radiation fibrosis, muscle spasms, muscle pain, neuropathy, and limited shoulder function are all potential side effects of breast cancer treatment and breast reconstruction. Post-mastectomy pain syndrome affects 25-60% of people after breast surgery. The current review moves forward to explain interventional pain management options that can be used to supplement conservative measures (physical therapy, medication, topical ointments) to help these patients.

RECENT FINDINGS

There are many new interventional procedures to treat chest wall pain, neuropathic pain, and spasticity after breast surgery. Currently, the most commonly performed procedures are botulinum toxin injections, serratus anterior plane blocks, intercostobrachial nerve blocks, thoracic paravertebral nerve blocks, pectoralis nerve blocks, and erector spinae nerve blocks. Utilizing one of these interventional procedures, along with physical therapy and pharmacologic interventions, can help manage post-mastectomy pain syndrome in the millions of breast cancer patients diagnosed and treated every year.

Impact of Regional Anesthesia on Subjective Quality of Recovery in Patients Undergoing Thoracic Surgery: A Systematic Review and Meta-Analysis

OBJECTIVES

Regional anesthesia can be effective for managing pain after thoracic surgery. This study evaluated whether it can also improve patient-reported quality of recovery (QoR) after such surgery.

DESIGN

Meta-analysis of randomized controlled trials.

SETTING

Postoperative care.

INTERVENTION

Perioperative regional anesthesia.

PATIENTS

Adults undergoing thoracic surgery.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was total QoR scores 24 hours after surgery. Secondary outcomes were postoperative opioid consumption, pain scores, pulmonary function, respiratory complications, and other adverse effects. Eight studies were identified, of which 6 involving 532 patients receiving video-assisted thoracic surgery were included in the quantitative analysis of QoR. Regional anesthesia significantly improved QoR-40 score (mean difference 9.48; 95% CI 3.53-15.44; I2 = 89%; 4 trials involving 296 patients) and QoR-15 score (mean difference 6.7; 95% CI 2.58-10.82; I2 = 0%; 2 trials involving 236 patients). Regional anesthesia also significantly reduced postoperative opioid consumption and the incidence of nausea and vomiting. Insufficient data were available to meta-analyze the effects of regional anesthesia on postoperative pulmonary function or respiratory complications.

CONCLUSIONS

The available evidence suggests that regional anesthesia can enhance QoR after video-assisted thoracic surgery. Future studies should confirm and extend these findings.

Effects of Thoracic Paravertebral Block on Postoperative Anxiety and Depression for Patients Undergoing Thoracoscopic Lung Cancer Radical Surgery

This study is aimed at investigating the effect of thoracic paravertebral block (TPVB) on the occurrence of chronic postoperative pain, postoperative anxiety, and depression in patients undergoing thoracoscopic radical lung cancer surgery. A total of 120 patients who underwent thoracoscopic radical lung cancer surgery in our hospital from June 2019 to March 2021 were included. There were 62 males and 58 females, with an age of 18-75 years old and a body mass index of 20-28 kg/m2. Patients were divided into two groups using the random number table method, TPVB group (n = 60) and normal saline group (control group, n = 60). Two-point nerve block was performed at T5-6 and T6-7 levels. Patients in the TPVB group received nerve block with 15 mL of 0.375% ropivacaine hydrochloride, while those in the control group received 5 mL of 0.9% normal saline. The numeric rating scale (NRS) scores at rest and during movement at 24 and 48 hours after surgery and the number of times the button on the patient-controlled analgesia pressed at 24 h after surgery in two groups were recorded. All patients were followed up by outpatient visits or phone visits at 1 year after surgery and assessed using Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) pain scale and Hospital Anxiety and Depression Scale (HADS). According to the inclusion, exclusion, and drop-out criteria, 108 patients were finally included, with 52 patients in the TPVB group and 56 patients in the control group. There was no statistically significant difference between the two groups in terms of age, sex, height, body weight, body mass index, ASA classification, and operation time (P > 0.05). NRS pain scores at 24 h (P = 0.0108) and 48 h (P = 0.0000) after surgery, the number of times pressing patient-controlled analgesia at 24 h after surgery (P = 0.0000), the LANSS scores (P = 0.0000), HADS anxiety score (P = 0.0000), and depression scores (P = 0.0000) at 1 year after surgery in the TPVB group were both significantly lower than those in the control group. To sum up, ultrasound-guided TPVB can effectively relieve pain at 48 hours after thoracoscopic lung cancer radical surgery and chronic postoperative pain at 6 months after V thoracoscopic lung cancer radical surgery.
