[PMID: 38725919 PMCID: PMC11078230 DOI: 10.5812/aapm-143369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Revised: 12/24/2023] [Accepted: 01/12/2024] [Indexed: 05/12/2024] Open
Abstract
Background Postoperative pain management is crucial for improving patient outcomes following posterior cervical spine surgery. Opioids are effective but carry a risk of respiratory depression. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used but may not provide adequate pain relief and have potential complications. The inter-semispinalis plane (ISPB) block is a novel technique for postoperative analgesia in cervical spine surgery. Objectives This study aims to evaluate and compare the efficacy of the ISPB with general anesthesia in terms of analgesia, postoperative Visual Analog Scale (VAS) pain scores, patient-surgeon satisfaction levels, and the occurrence of postoperative complications. Methods This double-blind, randomized controlled trial was blinded to both the patient and the assessor. Fifty adult patients (18 - 60 years old) undergoing elective posterior cervical spine surgery were enrolled. The participants were divided into 2 groups: The ISPB group (receiving bilateral ultrasound-guided ISPB at the C5 level) and the control group (receiving general anesthesia only), with each group comprising 25 patients. The study assessed intraoperative fentanyl use, postoperative VAS pain levels, the need for rescue analgesia, and complications. Results The ISPB group showed significantly lower intraoperative fentanyl consumption (median 100 vs. 100 - 150 μg, P = 0.022) and lower postoperative pain scores at 1, 8, 12, and 48 hours (P = 0.016, 0.009, 0.005, 0.016). Additionally, the ISPB group required less postoperative pethidine (20% vs. 64%, P = 0.002) and had a longer delay before requesting pethidine (hazard ratio 0.215, P = 0.001). Surgeon satisfaction was significantly higher in the ISPB group (P = 0.003). These results suggest that the ISPB can effectively reduce pain and analgesic requirements. Conclusions The ISPB is an effective analgesic technique for posterior cervical spine surgery, reducing opioid consumption, providing better pain control, and enhancing surgeon satisfaction without increasing complications. This approach has the potential to improve postoperative care and patient outcomes in this surgical population.

Perioperative analgesic efficacy and safety of erector spinae plane block in posterior cervical spine surgery-a double blinded, randomized controlled study. Spine J 2023; 23:6-13. [PMID: 35470087 DOI: 10.1016/j.spinee.2022.04.010] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 04/10/2022] [Accepted: 04/11/2022] [Indexed: 02/08/2023]
Abstract
BACKGROUND CONTENT Posterior cervical spine surgery (PCSS) are typically open surgeries and entail significant postoperative pain. Current perioperative pain management in PCSS is reliant on multimodal analgesia. While perioperative epidural anesthetic infusion can be used in lumbar surgeries, this is not an option in the cervical spine. Pre-emptive regional analgesia through erector spinae plane block (ESPB) has shown significant perioperative analgesic benefits in lumbar spine surgeries. There are no such clinical studies in PCSS. PURPOSE To assess the safety and efficacy of ultrasound-guided ESPB for perioperative analgesia in PCSS. STUDY DESIGN Prospective, randomized controlled, double-blinded study. PATIENT SAMPLE Eighty-six patients requiring sub-axial PCSS with or without instrumentation were randomized into two groups, those who underwent ESPB with multimodal analgesia (case) and those with only multimodal analgesia (control). OUTCOME MEASURES Demographic and surgical data (blood loss, duration of surgery, perioperative total opioid consumption, muscle relaxants used) were assessed. Postoperatively, the surgical site pain, alertness scale, satisfaction score, time to mobilization and complications were recorded. METHODS After anesthesia and prone position, case patients received ultrasound-guided ESPB at the T1 level using 15 ml of 0.25% bupivacaine and 8 mg Dexamethasone bilaterally while the control patients received only standard postoperative multimodal analgesia. RESULTS There were 43 patients in each group; the two groups were identical in demographic and surgical profile. The intraoperative opioid consumption (119.53±40.35 vs. 308.6±189.78; p<.001) in mcg), muscle relaxant usage (50.00±0.00 mg vs. 59.53±3.75 mg, p<.001), surgical duration (124.77±26.63/ 156.74±37.01 min; p<.01) and intraoperative blood loss (310.47±130.73 ml vs. 429.77±148.50 ml; p<.05) were significantly less in the ESPB group. In the postoperative period, the control group's pain score was significantly higher (p<.001). The Modified Observer Alertness/Sedation Score (MOASS) score and satisfaction scores also showed significant differences between the case and control groups (p<.001). The mean time required to ambulate (sitting/walking) was statistically less in cases (15.81±6.15/20.72±4.02 h) when compared to controls (16.86±6.18/ 23.05±8.88 h; p<.001). CONCLUSION In patients undergoing PCSS, ESPB is a safe and effective technique with better outcomes than standard multimodal analgesia alone, in terms of reduced intraoperative opioid requirements and blood loss, better postoperative analgesia and early mobilization.

Abstract
STUDY OBJECTIVE We evaluated the perioperative analgesic effects of the inter-semispinal plane (ISP) block in patients undergoing posterior cervical spine surgery. DESIGN Prospective, randomized, controlled, double-blinded trial. SETTING Operating room and surgical ward. PATIENTS 60 patients aged 18-60 years of either gender, ASA I-II, undergoing elective posterior cervical spine surgery. INTERVENTIONS Patients were randomly assigned into a control group (general anesthesia only), ISP group received bilateral ultrasound guided ISP block at the level of C5 using 20 ml bupivacaine 0.25% on each side. MEASUREMENTS Visual analog scale (VAS), intraoperative fentanyl and 24 h postoperative pethidine consumptions and time to first rescue analgesic request were documented. MAIN RESULTS The median (quartiles) of 24 h postoperative rescue pethidine consumption was significantly lower in the ISP group [0 (0-46.25) mg] compared to that of the control group [143 (116.75-169.00) mg]; P < 0.001). VAS was significantly lower in the ISP group at 30 min, 1 h, 2 h,4 h, 6 h, 8 h and 12 h postoperative compared to control group (P < 0.05). At 18 and 24 h, VAS was not significantly different between groups. The median (quartiles) of intraoperative fentanyl consumption in the ISP group [0 (0-40.75) μg] was significantly lower compared to that of the control group [63.5 (39.5-90.25) μg]; P < 0.001]. The time to first rescue analgesic administration was significantly longer in the ISP group compared to the control group (P < 0.001). CONCLUSION Bilateral ultrasound-guided ISP block can provide decreased 24 h postoperative analgesic consumption as well as lower pain scores in the first 12 postoperative hours in patients undergoing posterior cervical spine surgery.

Abstract
STUDY DESIGN A prospective multicenter study. OBJECTIVE This study aims to evaluate patient-reported outcomes using the Japanese Orthopedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) and clarify clinical factors that affect the therapeutic effects for patients with cervical ossification of the posterior longitudinal ligament (OPLL). SUMMARY OF BACKGROUND DATA Although previous studies identified factors that affected the surgical outcomes, their assessment was mainly based on the Japanese Orthopedic Association score, which only includes neurological function. Investigating this pathology through multiple functions and quality of life (QOL) is pivotal to understanding the comprehensive clinical pictures of the cervical OPLL and its therapeutic outcomes. MATERIALS AND METHODS This study was performed by the Japanese Multicenter Research Organization for Ossification of the Spinal Ligament. A total of 478 patients with myelopathy caused by cervical OPLL from 28 institutions were prospectively registered from 2014 to 2017 and followed up for 2 years. Of the patients, 168 received laminoplasties and fully completed questionnaires. Demographic information, imaging findings, and clinical outcomes were collected. Patients were grouped according to effective or ineffective surgical outcomes as defined by the JOACMEQ using logistic regression analyses. RESULTS Laminoplasty resulted in functional improvement in the cervical spine and upper extremity around 40% of the patients, while QOL showed only 21.4% ( P <0.01). Multivariable analyses revealed that younger age and a postoperative decrease in arm or hand pain were correlated with significantly improved function of the upper extremities. A reduction in lower limb pain favorably affected the postoperative lower extremity function. A postoperative reduction in upper extremity pain enhanced the QOL recovery. CONCLUSIONS Surgeons should recognize the diversity of surgical outcomes after laminoplasty and understand the necessity of pain management even after the surgery to enhance bodily functions and QOL in patients with cervical OPLL.

Local Infiltration Analgesia Versus Femoral Nerve Block for Pain Control in Anterior Cruciate Ligament Reconstruction: A Systematic Review With Meta-analysis. Orthop J Sports Med 2021; 9:23259671211050616. [PMID: 34796241 PMCID: PMC8593291 DOI: 10.1177/23259671211050616] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Accepted: 07/26/2021] [Indexed: 11/17/2022] Open
Abstract
Background: Anterior cruciate ligament reconstruction (ACLR) is often performed on an outpatient basis; thus, effective pain management is essential to improving patient satisfaction and function. Local infiltration analgesia (LIA) and femoral nerve block (FNB) have been commonly used for pain management in ACLR. However, the comparative efficacy and safety between the 2 techniques remains a topic of controversy. Purpose: To compare pain reduction, opioid consumption, and side effects of LIA and FNB after ACLR. Study Design: Systematic review; Level of evidence, 3. Methods: A systematic search of MEDLINE, Embase, and Cochrane Library databases was performed to identify studies comparing pain on the visual analog scale (a 100-mm scale), total morphine-equivalent consumption, and side effects between the 2 techniques after ACLR at the early postoperative period. The LIA was categorized into intra-articular injection and periarticular injection, and subgroup analyses were performed comparing either intra-articular injection or periarticular injection with FNB. Two reviewers performed study selection, risk-of-bias assessment, and data extraction. Results: A total of 10 studies were included in this systematic review and meta-analysis. In terms of VAS pain scores, our pooled analysis indicated that FNB was significantly more effective at 2 hours postoperatively compared with LIA (mean difference, 8.19 [95% confidence interval (CI), 0.75 to 15.63]; P = .03), with no significant difference between the 2 techniques at 4, 8, and 12 hours postoperatively; however, LIA was significantly more effective at 24 hours postoperatively compared with FNB (mean difference, 5.61 [95% CI, −10.43 to −0.79]; P = .02). Moreover, periarticular injection showed a significant improved VAS pain score compared with FNB at 24 hours postoperatively (mean difference, 11.44 [95% CI, −20.08 to −2.80]; P = .009), and the improvement reached the threshold of minimal clinically important difference of 9.9. Total morphine-equivalent consumption showed no difference between the 2 techniques, and side effects were unable to be quantified for the meta-analysis because of a lack of data. Conclusion: Compared with FNB, LIA was not as effective at 2 hours, comparable within 12 hours, and significantly more effective at 24 hours postoperatively for reducing pain after ACLR. Total morphine-equivalent consumption showed no significant differences between the 2 techniques.

Abstract
BACKGROUND The purpose of this study was to investigate the efficacy of gelatin sponge impregnated with ropivacaine on postoperative pain after transforaminal lumbar interbody fusion (TLIF) in patients with lumbar degenerative diseases. METHODS We retrospectively reviewed patients who underwent TLIF in our department between August 2018 and January 2020. Patients were divided to ropivacaine group and saline group. A ropivacaine group whom received gelatin sponge impregnated with ropivacaine during operation, and a saline group whom were intraoperatively administered by gelatin sponge impregnated with saline. The two groups were compared in reference to postoperative hospital stay, postoperative complications and visual analog scale (VAS) scores. The consumption of postoperative diclofenac sodium suppository use was also recorded. The Oswestry Disability Index (ODI) scores and Japanese Orthopedic Association (JOA) scores were used for functional evaluation at 1 year postoperatively. RESULT A total of 127 patients were evaluated in this retrospective study. The mean postoperative hospital stay in the ropivacaine group was significantly lower than saline group. The VAS score was significantly lower in patients receiving gelatin sponge impregnated with ropivacaine as compared with patients in saline group on postoperative day 1, 2, 3 and 4. The number of patients who need the administration of diclofenac sodium suppository and the mean consumption of postoperative diclofenac sodium suppository was significantly lower in the ropivacaine group as compared with saline group. CONCLUSION The application of gelatin sponge impregnated with ropivacaine around the nerve root in patients undergoing TLIF can effectively control the postoperative pain and reduce postoperative hospital stay.

[PMID: 32179153 DOI: 10.1016/j.spinee.2020.03.001] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Revised: 03/02/2020] [Accepted: 03/04/2020] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Patients undergoing lumbar spinal surgery may experience considerable pain in the early postoperative period, and poor pain control after multilevel lumbar spinal fusion surgery is frequently associated with multiple complications and delayed discharge from hospital. PURPOSE The current study evaluated the efficacy and safety of preemptive analgesia with intrathecal morphine (ITM) in patients undergoing multilevel posterior lumbar spinal fusion surgery. STUDY DESIGN Double-blinded, randomized, controlled trial. PATIENT SAMPLE Ninety-two patients aged between 18 and 80 years who were scheduled to undergo elective lumbar laminectomy (L3-S1) and dual-level fusions. OUTCOME MEASURES The primary endpoint was the degree of postoperative pain at rest and during movement evaluated using a 10-point visual analogue scale. The secondary outcomes included the consumption of analgesics, the patient-assessed postoperative and satisfaction scores, adverse effects, time to first ambulation, and length of hospital stay. METHODS Patients were randomly allocated to either the ITM group that received 0.2 mg of ITM or the control (CON) group that received 2 ml of 0.9% saline as a skin infiltration 30 minutes prior to anesthesia induction. RESULTS The ITM group had a significantly lower visual analogue scale score than the CON group during the first 3 days postoperatively (at rest, P=0.000, during movement, P=0.000). The ITM group used significantly less sufentanil than the CON group in the first 3 days postoperatively (p=.000) in patient-controlled intravenous analgesia, as well as in supplemental analgesic demands. The ITM group reported a greater degree of satisfaction with the whole hospitalization experience than the CON group (2.4±0.6 vs. 1.9±0.6, p=.000). The two groups did not significantly differ regarding adverse effects, length of hospital stay, and time taken to regain the ability to walk without support. CONCLUSIONS Preemptive analgesia with ITM results in significantly improved early postoperative pain control and decreased postoperative patient-controlled intravenous analgesia consumption, with no increase in adverse effects.

Abstract
OBJECTIVE Controversy still exists regarding the efficiency and safety of liposomal bupivacaine (LB) vs interscalene nerve block (INB) for pain management after total shoulder arthroplasty (TSA). The aim of the present meta-analysis was to perform a relatively credible and overall assessment to compare the efficiency and safety of LB-based infiltration vs INB for pain management after TSA. METHODS The PubMed, Cochrane Library, Web of Science, and EMBASE were systematically searched. Only studies published up to March 2018 comparing LB vs INB for pain control after TSA were included. The primary outcome extracted from the studies was postoperative pain score at different periods. The secondary outcomes included total opioid consumption, length of hospital stay, and complications. RESULTS Seven studies with 707 patients were included in this study. No statistically significant difference was observed between the LB and INB groups in pain scores at 8 hours, 12 hours, 24 hours, postoperative day (POD) 1, and POD 2. The two groups also showed comparable total opioid consumption at POD 0, POD 1, POD 2, and length of hospital stay. The LB group had a significantly higher pain score at 4 hours (standard mean difference =0.65, 95% CI=0.07 to 1.24, P=0.03) but a lower occurrence rate of complications than did the INB group (OR =0.51, 95% CI=0.28 to 0.91, P=0.02). CONCLUSION This meta-analysis revealed that INB provides excellent analgesic effects within 4 hours after TSA, while patients treated with LB infiltration experienced significantly less occurrence rate of complications after TSA. In general, both approaches provide similar overall pain relief and have similar opioid consumption after TSA, with no significant difference in the length of hospital stay. Nevertheless, more high-quality randomized controlled trails with long-term follow-up are still required to make the final conclusion.

Abstract
OBJECTIVE This meta-analysis aimed to compare the efficiency and safety of local liposomal bupivacaine infiltration and traditional cocktail analgesia for pain management in total hip arthroplasty (THA). METHODS PubMed, Embase, Web of science, Medline, and Cochrane library databases were systematically searched. INCLUSION CRITERIA Participants: patients planned for a THA with a diagnosis of hip osteoarthritis. INTERVENTIONS liposomal bupivacaine was administrated in the experimental groups for pain control. Comparisons: the control groups received local infiltration of traditional analgesics. OUTCOMES pain scores, opioids consumption, and postoperative complications among the patients. STUDY DESIGN randomized control trials (RCTs) and non-RCTs. Methodological Index for Non-Randomized Studies scale was used to assess the methodological quality of the included studies. Meta-analysis was conducted by Stata 11.0 software. Systematic review registration number is CRD42017120981. RESULTS Four articles involving 308 participants were included. Current meta-analysis revealed that there were significant differences regarding postoperative pain score at 12 hours (standard mean difference [SMD] = -0.496, 95% CI: -0.717 to -0.275, P = .000), 24 hours (SMD = -0.537, 95% CI: -0.760 to -0.313, P = .000), and 48 hours (SMD = -0.802, 95% CI: -1.029 to -0.576, P = .000). Liposomal bupivacaine intervention was found to significantly decrease opioid consumption at 12 hours (SMD = -0.544, 95% CI: -0.766 to -0.323, P = .000), 24 hours (SMD = -0.357, 95% CI: -0.577 to -0.138, P = .001), and 48 hours (SMD = -0.370, 95% CI: -0.589 to -0.151, P = .001). CONCLUSION Local liposomal bupivacaine infiltration could significantly reduce visual analogue scale (VAS) scores and opioid consumption within the first 48 hours following THA surgery. In addition, there was a decreased risk of nausea and vomiting in liposomal bupivacaine groups. The overall evidence level was low, which means that further research is likely to significantly alter confidence levels in the effect, as well as potentially changing the estimates. In any subsequent research, further studies should focus on the optimal dose of local anesthetics and the potential adverse side effects. In addition, surgeries that can improve pain relief and enable faster rehabilitation and earlier discharges should also be explored. Several potential limitations of this study should be noted. Four articles are included and the sample size in each trial is small. Some important outcome parameters such as range of motion were not fully described and could not be included in the meta-analysis. All included studies were retrospectives which may decrease evidence levels for the meta-analysis. The evidence quality for each outcome was low which may influence the results of the meta-analysis. Short-term follow-ups may lead to the underestimation of complications, such as neurotoxicity and cardiotoxicity. Publication bias is an inherent weakness that exists in all meta-analyses.

Abstract
BACKGROUND This meta-analysis aimed to compare the efficiency and safety of liposomal bupivacaine infiltration and interscalene nerve block for pain control after total shoulder arthroplasty. METHODS A systematic search was performed in Medline (1966 to May 2017), PubMed (1966 to May 2017), Embase (1980 to May 2017), ScienceDirect (1985 to May 2017) and the Cochrane Library. Only randomized controlled trials (RCTs) were included. Reported surgical outcomes, including visual analogue scale (VAS) scores, opioid consumption, length of stay, and postoperative adverse effects including the risk of nausea and vomiting. Meta-analysis was performed using Stata 11.0 software. RESULTS Four RCTs including 510 patients met the inclusion criteria. The present meta-analysis indicated that there were no significant differences between groups in terms of VAS score at 12 hours (standard mean difference [SMD] = 0.272, 95% CI: -0.150 to 0.695, P = .207), 24 hours (SMD = -0.056, 95% CI: -0.458 to 0.346, P = 0.785), and 48 hours (SMD = 0.183, 95% CI: -0.148 to 0.513, P = .278). Liposomal bupivacaine infiltration groups required an equivalent amount of opioids at postoperative 12 hours (SMD = -0.039, 95% CI: -0.222 to 0.143, P = .672), 24 hours (SMD = 0.046, 95% CI: -0.136 to 0.228, P = .618) and 48 hours (SMD = -0.025, 95% CI: -0.207 to 0.157, P = .785). CONCLUSION Liposomal bupivacaine infiltration provides equivalent postoperative pain control compared with interscalene nerve block following total shoulder arthroplasty. Both of them can reduce the consumption of opioids without severe adverse effects. More high-quality RCTs with long follow-up period are necessary for proper comparisons of the efficacy and safety of liposomal bupivacaine infiltration with interscalene nerve block.

Abstract
BACKGROUND This meta-analysis aimed to evaluate the efficiency and safety of transcutaneous electrical nerve stimulation (TENS) for pain control after total knee arthroplasty. METHODS A systematic search was performed in Medline (1966 to June 2017), PubMed (1966 to June 2017), Embase (1980 to June 2017), ScienceDirect (1985 to June 2017), and the Cochrane Library. Only randomized controlled trial (RCT) was included. The fixed/random effect model was used according to the heterogeneity tested by I statistic. Meta-analysis was performed using Stata 11.0 software. RESULTS Five RCTs including 472 patients met the inclusion criteria. The present meta-analysis indicated that there were significant differences between groups in terms of visual analogue scale score at 12 hours (average: 3.58 vs 4.34, SMD = -0.260, 95% CI: -0.442 to -0.078, P = .005), 24 hours (average: 3.18 vs 3.52, SMD = -0.244, 95% CI: -0.426 to -0.063, P = .008), and 48 hours (average: 2.70 vs 2.96, SMD = -0.214, 95% CI: -0.395 to -0.033, P = .021) after total knee arthroplasty. Significant differences were found regarding opioid consumption at 12 hours (average: 14.44 vs 18.54, SMD = -0.503, 95% CI: -0.687 to -0.319, P = .000), 24 hours (average: 16.10 vs 18.40, SMD = -0.262, 95% CI: -0.443 to -0.080, P = .005), and 48 hours (average: 12.92 vs 15.12, SMD = -0.183, 95% CI: -0.364 to -0.002, P = .048). CONCLUSION TENS could significantly reduce pain and opioid consumption after total knee arthroplasty. In addition, there were fewer adverse effects in the TENS groups. Higher quality RCTs are required for further research.

Abstract
STUDY DESIGN Prospective randomized controlled study. OBJECTIVES To determine the effect of collar-aided fixation on outcomes after laminoplasty for cervical compressive myelopathy. SUMMARY OF BACKGROUND DATA Patients are often placed in a Philadelphia collar for weeks after cervical laminoplasty. However, the benefit of postoperative collar use remains controversial. We hypothesized that treatment outcomes in postoperative pain in patients without collars would not be inferior to the outcomes in patients using Philadelphia collars for 2 weeks. METHODS This trial analyzed 74 patients (52 males, 22 females, mean age 72.7 years) with cervical compressive myelopathy who had undergone double-door laminoplasty. Before surgery, we randomly assigned patients to the collar-fixation (CF) group (postoperative Philadelphia collar for 2 weeks) or the no-collar (NC) group. The primary outcome was the visual analog scale (VAS) for cervical pain up to 1 year after surgery. Secondary outcomes were Japanese Orthopedics Association score, Short Form 36 score (SF-36), cervical range of motion (ROM), lordotic angle, and complications. RESULTS VAS scores up to 1 year after operation were similar with or without collar fixation (P = 0.487, two-way ANOVA). JOA scores improved significantly in both groups (P = 0.002 in CF, P < 0.001 in NC). There was no statistically significant difference between groups with regard to the improvement of JOA scores (54.9% in CF, 47.0% in NC, P = 0.80). The improvement in SF-36 was similar in both groups. Loss of ROM and lordotic angle of the cervical spine did not differ between groups (P = 0.61 in CF, P = 0.82 in NC). The incidence of complications was similar in both groups. CONCLUSION The VAS scores of cervical pain with the postoperative treatment without collar fixation were not inferior to those when using Philadelphia collars for 2 weeks. Moreover, other outcomes such as JOA scores, SF-36, ROM, lordotic angle, and complications were similar in both groups. LEVEL OF EVIDENCE 2.

Comparison of intrathecal and local infiltration analgesia by morphine for pain management in total knee and hip arthroplasty: A meta-analysis of randomized controlled trial. Int J Surg 2017; 40:97-108. [PMID: 28254422 DOI: 10.1016/j.ijsu.2017.02.060] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2016] [Revised: 02/15/2017] [Accepted: 02/17/2017] [Indexed: 02/07/2023]
Abstract
OBJECTIVE We performed a meta-analysis from randomized controlled trials to evaluate the efficiency and safety between local infiltration analgesia and intrathecal morphine for pain control in total knee and hip arthroplasty. METHODS We systemically searched electronic databases including Embase (1980-2016.7), Medline (1966-2016.7), PubMed (1966-2016.7), ScienceDirect (1985-2016.7), web of science (1950-2016.7) and Cochrane Library for relevant articles. All calculation was carried out by Stata 11.0. RESULTS Four randomized controlled trials (RCTs) involving 242 patients met the inclusion criteria. The meta-analysis showed that there were significant differences in terms of postoperative pain scores at 24 h during rest (P = 0.008) and mobilization (P = 0.049) following total knee and hip arthroplasty. Significant difference was found regarding the incidence of nausea (P = 0.030), vomiting (P = 0.005), and pruritus (P = 0.000) between two groups. There was no significant difference between groups in terms of morphine equivalent consumption at postoperative 24 or 48 h. CONCLUSIONS Local infiltration analgesia (LIA) provided superior analgesic effects within the first 24 h compared to intrathecal morphine (ITM) following total knee and hip arthroplasty. There were fewer adverse effects in LIA. Doses of morphine consumption were similar in the two groups.

Abstract
OBJECTIVE Total knee arthroplasty (TKA) is usually associated with postoperative pain. The objective of this systematic review and meta-analysis was to evaluate the effectiveness and safety of femoral nerve block compared with intrathecal morphine for pain management after TKA. METHODS Potentially relevant literature was identified from electronic databases including Medline, PubMed, Embase, ScienceDirect and the Cochrane Library. Gray academic studies were also identified from the reference of included literature. There was no language restriction. Pooling of data was carried out using Stata 11.0. RESULTS Four randomized controlled trials (RCTs) involving 185 patients met the inclusion criteria. The meta-analysis indicated that there were no significant differences in terms of Visual Analog Scale (VAS) score at 6 h (standard mean difference (SMD) = -0.09, 95% CI: -1.62 to 1.43, P = 0.903), 12 h (weighted mean difference (WMD) = 1.84, 95% CI: -8.01 to 11.69, P = 0.714) or 24 h (WMD = 1.56, 95% CI: -14.31 to 17.42, P = 0.8474). No significant difference were found regarding morphine consumption at 6 h (WMD = -0.84, 95% CI: -2.52 to 0.85, P = 0.332), 12 h (WMD = 0.031, 95% CI: -3.304 to 0.3366, P = 0.985), 24 h (WMD = 0.21, 95% CI: -7.32 to 7.75, P = 0.956) or incidence of postoperative vomit and nausea (risk difference (RD) = -0.01, 95% CI: -0.15 to 0.12, P = 0.847). There was a significant difference between the groups in terms of the risk of itching postoperatively (RD = 0.41, 95% CI: 0.29 to 0.54, P < 0.001). CONCLUSIONS Femoral nerve block provides equal postoperative pain control compared with intrathecal morphine following total knee arthroplasty, although there were fewer side effects in the FNB groups. In contrast, FNB was performed with an additional procedure and required a special apparatus. Both methods are effective at pain control following TKA.
