Paravertebral block associated with decreased opioid use and less nausea and vomiting after reduction mammaplasty

Regional anaesthesia: what surgical procedures, what blocks and availability of a “block room”?

PURPOSE OF REVIEW

With an expected rise in day care procedures with enhanced recovery programs, the use of specific regional anaesthesia can be useful. In this review, we will provide insight in the used regional block and medication so far known and its applicability in a day care setting.

RECENT FINDINGS

Regional anaesthesia has been improved with the aid of ultrasound-guided placement. However, it is not commonly used in the outpatient setting. Old, short acting local anaesthetics have found a second life and may be especially beneficial in the ambulatory setting replacing more long-acting local anaesthetics such as bupivacaine.To improve efficiency, a dedicated block room may facilitate the performance of regional anaesthesia. However, cost-efficacy for improved operating time, patient care and hospital efficiency has to be established.

SUMMARY

Regional anaesthesia has proven to be beneficial in ambulatory setting. Several short acting local anaesthetics are favourable over bupivacaine in the day care surgery. And if available, there are reports of the benefit of an additional block room used in a parallel (monitored) care of patients.

Nerve Blocks in Breast Plastic Surgery: Outcomes, Complications, and Comparative Efficacy

BACKGROUND

As plastic surgeons continue to evaluate the utility of nonopioid analgesic alternatives, nerve block use in breast plastic surgery remains limited and unstandardized, with no syntheses of the available evidence to guide consensus on optimal approach.

METHODS

A systematic review was performed to evaluate the role of pectoralis nerve blocks, paravertebral nerve blocks, transversus abdominus plane blocks, and intercostal nerve blocks in flap-based breast reconstruction, prosthetic-based reconstruction, and aesthetic breast plastic surgery, independently.

RESULTS

Thirty-one articles reporting on a total of 2820 patients were included in the final analysis; 1500 patients (53 percent) received nerve blocks, and 1320 (47 percent) served as controls. Outcomes and complications were stratified according to procedures performed, blocks employed, techniques of administration, and anesthetic agents used. Overall, statistically significant reductions in opioid consumption were reported in 91 percent of studies evaluated, postoperative pain in 68 percent, postanesthesia care unit stay in 67 percent, postoperative nausea and vomiting in 53 percent, and duration of hospitalization in 50 percent. Nerve blocks did not significantly alter surgery and/or anesthesia time in 83 percent of studies assessed, whereas the overall, pooled complication rate was 1.6 percent.

CONCLUSIONS

Transversus abdominus plane blocks provided excellent outcomes in autologous breast reconstruction, whereas both paravertebral nerve blocks and pectoralis nerve blocks demonstrated notable efficacy and versatility in an array of reconstructive and aesthetic procedures. Ultrasound guidance may minimize block-related complications, whereas the efficacy of adjunctive postoperative infusions was proven to be limited. As newer anesthetic agents and adjuvants continue to emerge, nerve blocks are set to represent essential components of the multimodal analgesic approach in breast plastic surgery.

Multimodal Analgesia in the Aesthetic Plastic Surgery: Concepts and Strategies

Postoperative pain management is crucial for aesthetic plastic surgery procedures. Poorly controlled postoperative pain results in negative physiologic effects and can affect length of stay and patient satisfaction. In light of the growing opioid epidemic, plastic surgeons must be keenly familiar with opioid-sparing multimodal analgesia regimens to optimize postoperative pain control.

Methods

A review study based on multimodal analgesia was conducted.

Results

We present an overview of pain management strategies pertaining to aesthetic plastic surgery and offer a multimodal analgesia model for outpatient aesthetic surgery practices.

Conclusion

This review article presents an evidence-based approach to multimodal pain management for aesthetic plastic surgery.

Spontaneous Ventilation Video-Assisted Thoracoscopic Surgery for Non-small-cell Lung Cancer Patients With Poor Lung Function: Short- and Long-Term Outcomes

Objective

The goal of this study was to explore the feasibility and safety of spontaneous ventilation video-assisted thoracoscopic surgery (SV-VATS) for non-small-cell lung cancer (NSCLC) patients with poor lung function.

Methods

NSCLC patients with poor lung function who underwent SV-VATS or mechanical ventilation VATS (MV-VATS) from 2011 to 2018 were analyzed. 1:2 Propensity score matching (PSM) was applied, and the short- and long-term outcomes between the SV-VATS group and the MV-VATS group were compared.

Results

Anesthesia time (226.18 ± 64.89 min vs. 248.27 ± 76.07 min; P = 0.03), operative time (140.85 ± 76.07 min vs. 163.12 ± 69.37 min; P = 0.01), days of postoperative hospitalization (7.29 ± 3.35 days vs. 8.40 ± 7.89 days; P = 0.04), and days of chest tube use (4.15 ± 2.89 days vs. 5.15 ± 3.54 days; P = 0.01), the number of N1 station lymph node dissection (2.94 ± 3.24 vs. 4.34 ± 4.15; P = 0.005) and systemic immune-inflammation index (3855.43 ± 3618.61 vs. 2908.11 ± 2933.89; P = 0.04) were lower in SV-VATS group. Overall survival and disease-free survival were not significantly different between the two groups (OS: HR 0.66, 95% CI: 0.41–1.07, P = 0.09; DFS: HR 0.78, 95% CI: 0.42–1.45, P = 0.43).

Conclusions

Comparable short-term and long-term outcomes indicated that SV-VATS is a feasible and safe method and might be an alternative to MV-VATS when managing NSCLC patients with poor lung function.

American Society of Plastic Surgeons Evidence-Based Clinical Practice Guideline Revision: Reduction Mammaplasty

SUMMARY

A multidisciplinary work group involving stakeholders from various backgrounds and societies convened to revise the guideline for reduction mammaplasty. The goal was to develop evidence-based patient care recommendations using the new American Society of Plastic Surgeons guideline methodology. The work group prioritized reviewing the evidence around the need for surgery as first-line treatment, regardless of resection weight or volume. Other factors evaluated included the need for drains, the need for postoperative oral antibiotics, risk factors that increase complications, a comparison in outcomes between the two most popular techniques (inferior and superomedial), the impact of local anesthetic on narcotic use and other nonnarcotic pain management strategies, the use of epinephrine, and the need for specimen pathology. A systematic literature review was performed, and an established appraisal process was used to rate the quality of relevant scientific research (Grading of Recommendations Assessment, Development and Evaluation methodology). Evidence-based recommendations were made and strength was determined based on the level of evidence and the assessment of benefits and harms.

Postoperative pain and opioid use after breast reduction with or without preoperative nerve block

BACKGROUND

Physician-prescribed opioids have been implicated as key contributing factors in the current opioid epidemic in the United States. Breast reduction mammoplasty is one of the most commonly performed procedures in plastic surgery and patients are often prescribed large amounts of postoperative opioids. Here we investigate the effects of erector spinae nerve blocks on postoperative pain, opioid consumption, and quality of life after breast reduction.

METHODS

Following the institutional review board (IRB) approval, a prospective cohort study of some patients undergoing breast reduction mammoplasty at Montefiore Medical Center between June and September 2019 was undertaken. The patients were stratified into two cohorts for further analysis: those who received preoperative erector spinae nerve block and those who did not. Primary outcomes measures analyzed included Likert pain scores, patient-reported outcome measures, and opioid consumption for the first five postoperative days.

RESULTS

Forty-seven patients were enrolled in the analysis. Thirteen patients (28%) received nerve blocks, 34 (72%) did not. On average, the patients were prescribed 114.3 (±34.6) morphine equivalents postoperatively and they consumed 45% (±35.3) by the end of the first five days post-surgery. There were no significant differences between cohorts in morphine equivalents prescribed or consumed, postoperative pain scores, or patient-reported outcome measures.

CONCLUSIONS

Following breast reduction mammoplasty, patients on average consumed < 50% of prescribed opioids, suggesting over-prescription of postoperative opioids for breast reduction recovery. Preoperative nerve block did not improve pain scores or decrease opioid consumption for the first five days after surgery.

Comparison of the analgesic effect of ultrasound-guided paravertebral block and ultrasound-guided retrolaminar block in Uniportal video-assisted Thoracoscopic surgery: a prospective, randomized study

Background

The optimal modality for postoperative analgesia after uniportal video-assisted thoracoscopic surgery (UVATS) for the treatment of lung cancer has not yet been determined. Both ultrasound-guided paravertebral block (PVB) and retrolaminar block (RLB) have been reported to be successful in providing analgesia after UVATS. However, which block technique provides superior analgesia after UVATS is still unclear. This randomized study was designed to compare the postoperative analgesic effects and adverse events associated with ultrasound-guided PVB and RLB after UVATS.

Methods

Sixty patients with lung cancer were randomized to undergo ultrasound-guided PVB (group P) or ultrasound-guided RLB (group R). In group P, 30 mL of 0.5% ropivacaine was injected at the T3 and T5 levels via ultrasound-guided PVB (15 mL at each level on the operative side). In group R, 30 mL of 0.5% ropivacaine was injected at the T3 and T5 levels via ultrasound-guided RLB (15 mL at each level on the operative side). The primary outcome was the numerical rating scale (NRS) score within 48 h after surgery. The secondary outcomes were total postoperative sufentanil consumption, time to first analgesic request and adverse events.

Results

At 3, 6, 12, 24, 36 and 48 h postoperatively, the NRS score at rest in group P was lower than that in group R (p < 0.05). At 3, 6, 12, 24 and 36 h postoperatively, the NRS score while coughing in group P was lower than that in group R (p < 0.05). The total postoperative sufentanil consumption in group P was significantly lower than that in group R (p < 0.001). Additionally, the time to first analgesic request was longer in group R than in group P (p < 0.0001). The incidence of nausea in group R was higher than that in group P (p < 0.05).

Conclusions

In patients with lung cancer undergoing UVATS, ultrasound-guided PVB with 0.5% ropivacaine provides better analgesia and results in less nausea than ultrasound-guided RLB. Compared with ultrasound-guided RLB, ultrasound-guided PVB seems to be a better technique for analgesia in UVATS.

Trial registration

The name of this study is the Effect And Mechanism Of Ultrasound-guided Multimodal Regional Nerve Block On Acute And Chronic Pain After Thoracic Surgery. This study was registered in the Chinese Clinical Trial Registry (ChiCTR2100044060). The date of registration was March 9, 2021.

Non-intubated spontaneous ventilation in video-assisted thoracoscopic surgery: a meta-analysis

It remains unclear whether non-intubated video-assisted thoracoscopic surgery (VATS) is comparable or advantageous compared with conventional intubated VATS. Thus, we systematically assessed the feasibility and safety of non-intubated VATS compared with intubated VATS perioperatively for the treatment of different thoracic diseases. An extensive search of literature databases was conducted. Perioperative outcomes were compared between 2 types of operations. The time trend of the overall results was evaluated through a cumulative meta-analysis. Subgroup analyses of different thoracic diseases and study types were examined. Twenty-seven studies including 2537 patients were included in the analysis. A total of 1283 patients underwent non-intubated VATS; intubated VATS was performed on the other 1254 patients. Overall, the non-intubated VATS group had fewer postoperative overall complications [odds ratios (OR) 0.505; P < 0.001]; shorter postoperative fasting times [standardized mean difference (SMD) -2.653; P < 0.001]; shorter hospital stays (SMD -0.581; P < 0.001); shorter operative times (SMD -0.174; P = 0.041); shorter anaesthesia times (SMD -0.710; P < 0.001) and a lower mortality rate (OR 0.123; P = 0.020). Non-intubated VATS may be a safe and feasible alternative to intubated VATS and provide a more rapid postoperative rehabilitation time than conventional intubated VATS.

Paravertebral Block versus Thoracic Epidural Analgesia for Postthoracotomy Pain Relief: A Meta-Analysis of Randomized Trials

OBJECTIVE

 Paravertebral block (PVB) and thoracic epidural analgesia (TEA) are commonly used for postthoracotomy pain management. The purpose of this research is to evaluate the effects of TEA versus PVB for postthoracotomy pain relief.

METHODS

 A systematic literature search was conducted in PubMed, EMBASE, Web of Science, and the Cochrane Library (last performed on August 2020) to identify randomized controlled trials comparing PVB and TEA for thoracotomy. The rest and dynamic visual analog scale (VAS) scores, rescue analgesic consumption, the incidences of side effects were pooled.

RESULTS

 Sixteen trials involving 1,000 patients were included in this meta-analysis. The pooled results showed that the rest and dynamic VAS at 12, 24, and rest VAS at 48 hours were similar between PVB and TEA groups. The rescue analgesic consumption (weighted mean differences: 3.81; 95% confidence interval [CI]: 0.982-6.638, p < 0.01) and the incidence of rescue analgesia (relative risk [RR]: 1.963; 95% CI: 1.336-2.884, p < 0.01) were less in TEA group. However, the incidence of hypotension (RR: 0.228; 95% CI: 0.137-0.380, p < 0.001), urinary retention (RR: 0.392; 95% CI: 0.198-0.776, p < 0.01), and vomiting (RR: 0.665; 95% CI: 0.451-0.981, p < 0.05) was less in PVB group.

CONCLUSION

 For thoracotomy, PVB may provide no superior analgesia compared with TEA but PVB can reduce side effects. Thus, individualized treatment is recommended. Further study is still necessary to determine which concentration of local anesthetics can be used for PVB and can provide equal analgesic efficiency to TEA.

Management strategies for the treatment and prevention of postoperative/postdischarge nausea and vomiting: an updated review

Postoperative nausea and vomiting (PONV) and postdischarge nausea and vomiting (PDNV) remain common and distressing complications following surgery. The routine use of opioid analgesics for perioperative pain management is a major contributing factor to both PONV and PDNV after surgery. PONV and PDNV can delay discharge from the hospital or surgicenter, delay the return to normal activities of daily living after discharge home, and increase medical costs. The high incidence of PONV and PDNV has persisted despite the introduction of many new antiemetic drugs (and more aggressive use of antiemetic prophylaxis) over the last two decades as a result of growth in minimally invasive ambulatory surgery and the increased emphasis on earlier mobilization and discharge after both minor and major surgical procedures (e.g. enhanced recovery protocols). Pharmacologic management of PONV should be tailored to the patient’s risk level using the validated PONV and PDNV risk-scoring systems to encourage cost-effective practices and minimize the potential for adverse side effects due to drug interactions in the perioperative period. A combination of prophylactic antiemetic drugs with different mechanisms of action should be administered to patients with moderate to high risk of developing PONV. In addition to utilizing prophylactic antiemetic drugs, the management of perioperative pain using opioid-sparing multimodal analgesic techniques is critically important for achieving an enhanced recovery after surgery. In conclusion, the utilization of strategies to reduce the baseline risk of PONV (e.g. adequate hydration and the use of nonpharmacologic antiemetic and opioid-sparing analgesic techniques) and implementing multimodal antiemetic and analgesic regimens will reduce the likelihood of patients developing PONV and PDNV after surgery.

Factors influencing the length of stay after mediastinal tumor resection in the setting of an enhanced recovery after surgery (ERAS)-TUBELESS protocol

Background

Prolonged length of stay after surgery is considered to increase cost and hospital-acquired complications. Therefore, we aimed to identify the risk factors that were associated with an increased length of stay after mediastinal tumor resection in the setting of an enhanced recovery after surgery (ERAS)-TUBELESS protocol.

Methods

This prospective cohort study collected data on consecutive patients undergoing video-assisted thoracoscopic surgery (VATS) resection for mediastinal tumor between December 2015 and November 2018 at a single center in China. All patients followed the ERAS-TUBELESS protocol. A length of stay after VATS tumor resection (LOS) greater than 3 days was considered an increased LOS. Univariable and multivariable logistic regression models were used to identify potential factors associated with increased LOS. Factors were divided into patient-related risk factors and procedure-related risk factors.

Results

A total of 204 patients were included, of which 85 (41.67%) patients had a LOS of more than 3 days. The median LOS for the entire cohort was 3 days. All the patient-related risk factors had no significantly associated with a prolonged LOS. Procedure-related risk factors that were significantly associated with a prolonged LOS were surgeon, operation time, intraoperative blood loss, drainage tube, analgesic drugs, and complications. Anesthesia with spontaneous ventilation was correlated with early discharge (LOS ≤1 day).

Conclusions

In the setting of an ERAS-TUBELESS protocol, the main drivers of LOS were procedure-related factors. Anesthesia with spontaneous ventilation was associated with early discharge (LOS ≤1 day) and thus promoted thoracic day surgery.

Basics and Best Practices of Multimodal Pain Management for the Plastic Surgeon

Pain management is a central focus for the plastic surgeon’s perioperative planning, and it no longer represents a postoperative afterthought. Protocols that rely on opioid-only pain therapy are outdated and discouraged, as they do not achieve optimal pain relief, increase postoperative morbidity, and contribute to the growing opioid epidemic. A multimodal approach to pain management using non-opioid analgesic techniques is an integral component of enhanced recovery after surgery protocols. Careful perioperative planning for optimal pain management must be achieved in multidisciplinary collaboration with the perioperative care team including anesthesiology. This allows pain management interventions to occur at 3 critical opportunities—preoperative, intraoperative, and postoperative settings.

Nonintubated Spontaneous Ventilation Offers Better Short-term Outcome for Mediastinal Tumor Surgery

BACKGROUND

Nonintubated spontaneous ventilation video-assisted thoracoscopic surgery (NI-VATS) has been investigated to reduce the adverse effects of tracheal intubation, mechanical ventilation, and general anesthesia in several thoracic diseases. We comparatively assess the comparison between NI-VATS vs intubated anesthesia VATS (I-VATS) on early outcomes of mediastinal lesion resection.

METHODS

Patients who underwent VATS resection for a mediastinal tumor between December 2015 and September 2018 were retrospectively included for analysis. Patients were divided into two groups according to anesthesia ventilation type: NI-VATS and I-VATS. Propensity score matching was applied to eliminate population bias. Intraoperative and postoperative variables were compared.

RESULTS

A total of 198 patients was included; 75 patients underwent NI-VATS and 123 patients underwent I-VATS. After propensity score matching, both anesthesia time (173.81 vs 227.37 minutes, P < .001) and operation time (82.82 vs 133.49 minutes, P < .001) were shorter in the NI-VATS group. Bleeding (51.80 mL vs 56.73 mL, P = .90) and postoperative morbidity (10.9% vs 15.6%, P = .57) were similar between groups. Chest tube duration (1.11 vs 1.54 days, P = .04) was shorter in the NI-VATS group. Hospital duration after surgery (3.15 vs 5.35 days, P < .001) was shorter in the NI-VATS group. D-dimer after surgery was significantly higher in both groups, but NI-VATS decreased the change (577 vs 1624 μg/L, P < .001). Furthermore, a decrease in the use of postoperative opioids analgesics was seen in the NI-VATS group (31% vs 51%, P = .023).

CONCLUSIONS

Mediastinal tumor resection is safe and feasible under NI-VATS. Better short-term outcomes suggest NI-VATS facilitates a more rapid recovery. Further multicenter prospective randomized investigation is warranted.

Surgeon perception versus reality: Opioid use after breast cancer surgery

BACKGROUND

Few guidelines exist for an opioid prescription after breast surgical oncology (BSO) procedures. We sought to characterize opioid prescribing and use patterns by surgery type.

METHODS

Patients (n = 332) undergoing BSO procedure were surveyed one week postoperatively for opioid use. The surgeons were surveyed about pain management preferences surgery type. CPT codes were collected for 2017 to calculate the amount of opioids used by surgery type relative to surgeon preference.

RESULTS

Mean oral morphine equivalent (OME) preferred prescription for surgeons who did not tailor prescriptions by surgery type (n = 7, group A) was 177, whereas for those who did tailor (n = 10, group B) varied from 137 to 257 OME. There was a significant difference in opioid use by surgery type: 32 OME for segmental mastectomy (SM) ± sentinel lymph node dissection (SLND), 63 for SM + axillary lymph node dissection (ALND), 76 for total mastectomy (TM) ± SLND, 115 for TM + ALND (P < 0.001). Considering the type of surgeries performed group A prescribers would have 229190 unused OME and group B would have 230826 in 1 year.

CONCLUSION

Wide variation in opioid use by BSO procedure type was noted with substantial unused OME regardless ofprescribing preference. Evidence-based guidelines are needed to tailor analgesic prescriptions according to the need.
