Multimodal Analgesia in Spine Surgery: An Umbrella Review

Differences in Perioperative Management of Patients Undergoing Complex Spine Surgery: A Global Perspective

BACKGROUND

The aim of this survey was to understand institutional spine surgery practices and their concordance with published best practices/recommendations.

METHODS

Using a global internet-based survey examining perioperative spine surgery practice, reported institutional spine pathway elements (n=139) were compared with the level of evidence published in guideline recommendations. The concordance of clinical practice with guidelines was categorized as poor (≤20%), fair (21%-40%), moderate (41%-60%), good (61%-80%), or very good (81%-100%).

RESULTS

Seventy-two of 409 (17.6%) institutional contacts started the survey, of which 31 (7.6%) completed the survey. Six (19.4%) of the completed surveys were from respondents in low/middle-income countries, and 25 (80.6%) were from respondents in high-income countries. Forty-one incomplete surveys were not included in the final analysis, as most were less than 40% complete. Five of 139 (3.6%) reported elements had very good concordance for the entire cohort; hospitals with spine surgery pathways reported 18 elements with very good concordance, whereas institutions without spine surgery pathways reported only 1 element with very good concordance. Reported spine pathways included between 7 and 47 separate pathway elements. There were 87 unique elements in the reviewed pathways. Only 3 of 87 (3.4%) elements with high-quality evidence demonstrated very good practice concordance.

CONCLUSIONS

This global survey-based study identified practice variation and low adoption rates of high-quality evidence in the care of patients undergoing complex spine surgery.

Efficacy and Safety of Ultrasound Guided Inter-semispinal Plane Block for Postoperative Analgesia in Posterior Cervical Laminectomy - A Prospective Randomised Controlled Study

STUDY DESIGN

Prospective, randomized controlled study.

OBJECTIVE

To assess the safety and efficacy of an ultrasound-guided ISP block for postoperative analgesia in posterior cervical laminectomy.

METHODS

88 patients requiring posterior cervical laminectomy were randomized into two groups, those who underwent ISP block with multimodal analgesia (ISPB group) and those with only multimodal analgesia (control group). Demographic details, intraoperative parameters (blood loss, duration of surgery, perioperative total opioid consumption, muscle relaxants used), and postoperative parameters (numeric rating scale, satisfaction score, mobilization time, and complications) were recorded.

RESULTS

The total opioid consumption (128.41 + 39.65vs 284.09 + 140.92mcg; P < .001), muscle relaxant usage (46.14 + 6.18 mg vs 59.32 + 3.97 mg; P < .001), surgical duration (128.61 + 26.08/160.23 + 30.99mins; P < .01), and intra-operative blood loss (233.18 + 66.08 mL vs 409.77 + 115.41 mL; P < .01) were significantly less in the ISPB group compared to the control. In the postoperative period, the control group's pain score was significantly higher (P < .001) in the initial 48 hours. The Modified Observer Alertness/Sedation Score (MOASS) score and satisfaction scores were significantly better in the ISPB compared to the control (P < .001). The mean time required to ambulate was statistically less in ISPB (4.30 + 1.64hours) when compared to controls (9.48 + 3.07hours) (P < .001).

CONCLUSION

In patients undergoing posterior cervical laminectomy, ISP block is a safe and effective technique with better outcomes than standard multi-modal analgesia alone, in terms of reduced intra-operative opioid requirements and blood loss, better postoperative analgesia, and early mobilization.

Pre-emptive infiltration with betamethasone and ropivacaine for postoperative pain in laminoplasty and laminectomy (PRE-EASE): a prospective randomized controlled trial

BACKGROUND

Postoperative pain after laminoplasty and laminectomy occurs partially from local trauma of the paraspinal tissue. Finding a multimodal analgesic cocktail to enhance the duration and effect of local infiltration analgesia is crucial. Because of the rapid onset and long duration of action of betamethasone, the authors hypothesized that, a pre-emptive multimodal infiltration regimen of betamethasone and ropivacaine reduces pain scores and opioid demand, and improves patient satisfaction following laminoplasty and laminectomy.

MATERIALS AND METHODS

This prospective, randomized, open-label, blinded endpoint study was conducted between 1 September 2021 and 3 June 2022, and included patients between the ages of 18 and 64 scheduled for elective laminoplasty or laminectomy under general anesthesia, with American Society of Anesthesiologists classification I/II. One hundred sixteen patients were randomly assigned to either the BR (Betamethasone-Ropivacaine) group or the R (Ropivacaine) group in a 1:1 ratio. Each group received pre-emptive infiltration of a total of 10 ml study solution into each level. Every 30 ml of study solution composed of 0.5 ml of betamethasone plus 14.5 ml of saline and 15 ml of 1% ropivacaine for the BR group, and 15 ml of 1% ropivacaine added to 15 ml of saline for the R group. Infiltration of epidural space and intrathecal space were avoided and the spinous process, transverse process, facet joints, and lamina were injected, along with paravertebral muscles and subcutaneous tissue. Cumulative 48 h postoperative butorphanol consumption via PCA (Patient-controlled analgesia) was the primary outcome. Intention-to-treat (ITT) principle was used for primary analysis.

RESULTS

Baseline characteristics were identical in both groups ( P >0.05). The cumulative 48 h postoperative butorphanol consumption via PCA was 3.0±1.4 mg in the BR group ( n =58), and 7.1±1.2 mg in the R group ( n =58) ( P <0.001). Overall cumulative opioid demand was lower at different time intervals in the BR group ( P <0.001), along with the estimated median time of first analgesia demand via PCA (3.3 h in the BR group and 1.6 h in the R group). The visual analog scale (VAS) score at movement and rest were also significantly lower until 3 months and 6 weeks, respectively. No side effects or adverse events associated with the intervention were observed in this study.

CONCLUSIONS

Pre-emptive analgesia with betamethasone and ropivacaine provides better postoperative pain management following laminoplasty and laminectomy, compared to ropivacaine alone. This is an effective technique worthy of further evaluation.

Effects of Pain Beliefs on Postoperative Pain and Analgesic Consumption in Spine Surgery Patients

ABSTRACT

PURPOSE: This study evaluates the impact of pain belief on postoperative pain and analgesic consumption in patients undergoing spine surgery. METHODS: This descriptive and cross-sectional study was conducted on 71 patients undergoing spine surgery, who were admitted to the neurosurgery department of a university hospital between January 2021 and April 2022. Descriptive information form, Pain Beliefs Questionnaire, visual analog scale, pain evaluation form, and verbal category scale were used for data collection. RESULTS: Participant mean age was 53 years, and 40.8% underwent spinal disc surgery. A total of 60.2% of the participants experienced moderate postoperative pain, and severe pain was noted during the second postoperative hour, after rest and coughing, which decreased significantly during consecutive hours. Besides, 70.4% of the participants expressed that the level of pain decreased, 43.7% had pain as they expected, 69.0% had intermittent pain, and 53.5% experienced pain at the surgical site. The mean scores obtained from the Organic and Psychological Beliefs subscales of the Pain Beliefs Questionnaire were 4.25 and 4.21, respectively. There was a statistically significant relationship between the Psychological Beliefs and visual analog scale scores after coughing measured in the postoperative 24th and 36th hours. There was also a significant relationship between organic beliefs and working status. There was no statistically significant relationship between analgesic consumption and pain belief. CONCLUSION: Patients undergoing spine surgery experienced moderate pain and had a relatively high level of pain beliefs. Regular evaluation of pain levels and beliefs is required for effective pain management.

CE: Overcoming Movement-Evoked Pain to Facilitate Postoperative Recovery

ABSTRACT

Severe postoperative movement-evoked pain (MEP) can be immobilizing, instilling in patients the fear that further activity will produce unbearable pain. This impedes healing and restoration of function while also extending time to recovery. Therefore, it is critical to manage MEP effectively through timely evaluation and comprehensive care planning. This article builds on recent calls to standardize testing of MEP to inform care planning in a way that both reduces pain and improves functioning. Subsequent reassessment of MEP can guide the refinement of therapy. Although this approach may seem intuitive, it challenges common practices that focus too heavily on pain intensity, resulting in overtreating, undertreating, or not treating pain, while ignoring the risks of immobility and the importance of movement for improving functional capacity. The authors propose a multifaceted approach to overcoming MEP that nurse clinicians, educators, researchers, and compliance professionals can use to enhance the quality and safety of nursing practice.

Ultrasound-guided erector spinae plane block for postoperative short-term outcomes in lumbar spine surgery: A meta-analysis and systematic review

BACKGROUND

Patients undergoing lumbar spine surgery usually suffer from moderate to severe acute pain. Erector spinae plane block (ESPB) has been applied to relieve acute pain in various surgeries and improve postoperative outcomes. This study aimed to further identify the efficacy and safety of erector spinae plane block in patients undergoing lumbar spine surgery. This study also evaluates the outcomes of the erector spinae plane block compared with other regional blocks.

METHODS

We searched PubMed, Web of Science, Cochrane library, Embase, and CINAHL databases to identify all randomized controlled trials evaluating the effects of ESPB on postoperative pain after lumbar spine surgery. The primary outcome is postoperative total opioid consumption in 24 hours. The secondary outcomes are postoperative pain scores, intraoperative opioid consumption, time to first rescue analgesia, number of patients requiring rescue analgesia, first time to ambulation after surgery, length of hospital stay, patients' satisfaction score, and postoperative side effects such as postoperative nausea and vomiting, itching.

RESULTS

A total of 19 randomized controlled trials are included in the final analysis. Compared with no/sham block, ultrasound-guided erector spinae plane block can decrease perioperative opioid consumption including intraoperative opioid consumption: standardized mean difference (SMD) = -3.04, 95% confidence interval (CI) (-3.99, -2.09), P < .01, and opioid consumption postoperatively: (SMD = -2.80, 95% CI [-3.61, -2.00], P < .01); reduce postoperative pain at 2, 6, 12, 24, and 48 hours both at rest and movement; meanwhile shorten time to hospital length of stay: (SMD = -1.01, 95% CI [-1.72, 0.30], P = .006), decrease postoperative nausea and vomiting (RR = 0.35, 95% CI [0.27, 0.46], P < .00001), and improve patient satisfaction (SMD = -2.03, 95% CI [-0.96, 3.11], P = .0002). But ultrasound-guided ESPB doesn't shorten the time to ambulation after surgery (SMD = -0.56, 95% CI [-1.21, 0.08], P = .09). Additionally, ESPB is not superior to other regional blocks (e.g., thoracolumbar interfascial plane/midtransverse process to pleura block).

CONCLUSION

This meta-analysis demonstrates that ultrasound-guided ESPB can provide effective postoperative analgesia in patients undergoing lumbar spine surgery and improve postoperative outcomes, and it deserves to be recommended as an analgesic adjunct in patients undergoing lumbar spine surgeries.

Efficacy and Safety of Erector Spinae Plane Block for Perioperative Pain Management in Lumbar Spinal Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background

Since the application of ultrasound-guided erector spinae plane block (ESPB) in 2016, the approach has been gradually applied to perioperative analgesia in various surgeries. In recent years, more and more studies have focused on the effect of ESPB in perioperative analgesia of lumbar spinal surgery, but its clinical effect remains controversial.

Objective

This systematic review and meta-analysis was designed to explore the efficacy and safety of ESPB used for perioperative pain management in lumbar spinal surgery.

Methods

The Pubmed, Web of Science, Cochrane Library, and EMBASE databases were comprehensively searched for relevant articles from inception to March 2022. Randomized controlled trials (RCTs) comparing ESPB with placebo or without ESPB in lumbar spinal surgery were included. The Review Manager 5.3 software was employed for this meta-analysis.

Results

Nineteen RCTs with 1381 participants were included for final analysis. ESPB group exhibited lower intraoperative consumption of sufentanil and remifentanil, lower total opioid consumption within 24 h and 48 h after surgery, lower incidence of rescue analgesia, longer time to first rescue analgesic and lower number of PCA button presses compared to the control group (P<0.05). Moreover, the ESPB group had significantly lower pain scores at rest and on movement within 48 h after surgery compared with the control group (P<0.05). In terms of opioid-related adverse reactions, ESPB reduced the incidence of postoperative nausea, vomitting, somnolence and itching in comparison to the control group (P<0.05). ESPB-related serious complications were not reported in included studies.

Conclusion

This meta-analysis demonstrated that ESPB used in lumbar spinal surgery was effective in relieving postoperative pain, decreasing the perioperative consumption of opioids, as well as decreasing the incidence of postoperative opioid-related adverse reactions.

Perioperative Multimodal Analgesia for Adults undergoing surgery of the Spine- Systematic Review and Meta-analysis of Three or More Modalities

BACKGROUND

Multimodal analgesia is a strategy which may be employed to improve pain management in the perioperative period in patients undergoing surgery of the spine. However, there is no review evidence available on quantitative models of multimodal analgesia within this clinical setting. We conducted a systematic review and meta-analysis to examine the impact of maximal (three or more analgesic agents) multimodal analgesic medication in patients undergoing surgery of the spine.

METHODS

We included randomized controlled trials (RCT's) evaluating the use of three or more multimodal analgesia components (maximal multi modal analgesia) in patients undergoing spinal surgery. We excluded patients receiving neuraxial or regional analgesia. The control group consisted of placebo, standard care (any therapeutic modality including two or less analgesic components). Primary outcomes were post-operative pain scores at rest, at twenty-four, and forty eight hours. We searched the MEDLINE via Ovid SP; EMBASE via Ovid SP; and Cochrane Library (Cochrane Database of Systematic Reviews and CENTRAL). We used Cochrane's standard methods.

RESULTS

We identified consistently improved analgesic endpoints across all pre-determined primary and secondary outcomes. A total of eleven eligible studies evaluated the primary outcome of pain at rest at twenty four hours. Patients receiving maximal multimodal analgesia were identified to have lower pain scores with an average of MD [-1.03], p<0.00001. Length of hospital stay was decreased in patients receiving multimodal analgesia MD [-0.55], p<0.00001.

CONCLUSION

Perioperative maximal multimodal analgesia consistently improves visual analogue scale outcomes in adult population in the immediate post-operative period, with a moderate quality of evidence. There is significant decrease in hospital length of stay in patients receiving maximal multimodal analgesia with a high level of evidence and no statistical heterogeneity.
