The effect of fascia iliaca compartment block on postoperative delirium in elder adults undergoing hip surgery: A systematic review and meta-analysis of randomized controlled trials. Int J Orthop Trauma Nurs 2024; 54:101122. [PMID: 39047334 DOI: 10.1016/j.ijotn.2024.101122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2024] [Revised: 07/01/2024] [Accepted: 07/18/2024] [Indexed: 07/27/2024]
Abstract
OBJECTIVE This meta-analysis aimed to evaluate whether fascia iliaca compartment block (FIB) could reduce the incidence of postoperative delirium (POD) in elderly patients undergoing hip surgery. METHODS This meta-analysis was registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42023490399). The PubMed, Embase, Web of Science, and Cochrane Library databases were searched for randomized controlled trials (RCTs) till November 15, 2023. Review Manger 5.4 was used to analyze the data. RESULTS A total of 10 RCTs with 930 elderly patients were included in this meta-analysis. This meta-analysis indicated that FIB could reduce the incidence of POD in elderly patients undergoing hip surgery without preoperative cognitive impairment (OR:0.46; 95%CI[0.22, 0.96], P = 0.04, I2 = 0%). Subgroup analysis of the incidence of POD showed that elderly patients who received FIB treatment before entering the operating room had a lower risk of developing POD(OR:0.48; 95%CI[0.30, 0.76], P = 0.002, I2 = 0%), and FIB could reduce the occurrence of POD in patients undergoing intravertebral anesthesia instead of general anesthesia (OR:0.37; 95%CI[0.20, 0.66], P﹤0.01, I2 = 0%). Moreover, FIB could reduce the MMSE score on the first day after surgery (SMD:1.07; 95%CI[0.15, 1.99], P = 0.02, I2 = 86%). In addition, FIB could reduce the pain score on the first and third day after surgery (SMD: -0.46; 95%CI[-0.74, -0.18], P = 0.001, I2 = 43%; SMD: -0.62; 95%CI[-0.97, -0.26], P﹤0.001, I2 = 58%), as well as after physical activity(SMD: -1.64; 95%CI[-3.00, -0.28], P = 0.02, I2 = 83%). CONCLUSION FIB can reduce the incidence of POD in elderly patients undergoing hip surgery without pre-existing cognitive impairment. Additionally, it can lower the delirium scores and pain scores.

Abstract
INTRODUCTION Postoperative cognitive impairment is common in surgical patients, including postoperative delirium and postoperative cognitive dysfunction. Several studies investigating the association between peripheral nerve block and the risk of cognitive impairment after thoracic surgery showed conflicting results. Therefore, we conducted the current systematic review and meta-analysis to determine the effects of peripheral nerve block on postoperative cognitive impairment in thoracic surgical patients. EVIDENCE ACQUISITION Eligible randomized controlled trials were retrieved from PubMed, Cochrane Library, Web of Science and Embase databases. The primary outcomes were the incidence of postoperative delirium or cognitive dysfunction and the MMSE scores. Furthermore, VAS scores, levels of TNF-α and IL-6, as well as the duration of hospitalization were analyzed as secondary outcomes. EVIDENCE SYNTHESIS Ten articles including 1279 participants were selected for this meta-analysis. The results showed that peripheral nerve block could lessen the incidence of postoperative delirium or cognitive dysfunction (OR=0.39, 95% CI [0.27 to 0.56]), the scores of VAS (MD=-1.35 [95% CI: -2.30 to -0.40]), the values of TNF-α (SMD=-1.13 [95% CI: -1.49 to -0.76]) and IL-6 (SMD=-1.65 [95% CI: -1.87 to -1.42]), as well as the length of hospitalization (MD=-0.70 [95% CI: -0.96 to -0.43]). In addition, peripheral nerve block was linked to a significant increase in MMSE scores (MD=2.16 [95% CI: 1.40 to 2.91]). CONCLUSIONS This meta-analysis revealed positive effects of peripheral nerve block on improving postoperative cognitive impairment in patients following thoracic surgery.

Abstract
Background Nerve blocks are widely used in various surgeries to alleviate postoperative pain and promote recovery. However, the impact of nerve block on delirium remains contentious. This study aims to systematically evaluate the influence of Thoracic Paravertebral Nerve Block (TPVB) on the incidence of delirium in patients post Video-Assisted Thoracoscopic Surgery (VATS). Methods We conducted a systematic search of PubMed, Embase, Web of Science, Cochrane Library, and Scopus databases in June 2023. The search strategy combined free-text and Medical Subject Headings (MeSH) terms, including perioperative cognitive dysfunction, delirium, postoperative cognitive dysfunction, paravertebral nerve block, thoracic surgery, lung surgery, pulmonary surgery, and esophageal/esophagus surgery. We utilized a random effects model for the analysis and synthesis of effect sizes. Results We included a total of 9 RCTs involving 1,123 participants in our study. In VATS, TPVB significantly reduced the incidence of delirium on postoperative day three (log(OR): -0.62, 95% CI [-1.05, -0.18], p = 0.01, I2 = 0.00%) and postoperative day seven (log(OR): -0.94, 95% CI [-1.39, -0.49], p < 0.001, I2 = 0.00%). Additionally, our study indicates the effectiveness of TPVB in postoperative pain relief (g: -0.82, 95% CI [-1.15, -0.49], p < 0.001, I2 = 72.60%). Conclusion The comprehensive results suggest that in patients undergoing VATS, TPVB significantly reduces the incidence of delirium and notably diminishes pain scores.

Abstract
Ultrasound (US) technology has significantly expanded the spectrum of regional anesthesiological procedures in recent years. Abdominal wall blocks are becoming an increasingly integral part of a multimodal postoperative pain concept after abdominal surgery, gynecological or urological interventions. Thoracic epidural analgesia remains the gold standard for extensive surgery. The requirement for rapid postoperative mobilization and discharge after lower extremity surgery has led to the abandonment of neuroaxial or plexus blocks in favor of selective, peripheral blocks such as the PENG block or adductor canal block. The following article is intended to show the reader the change in the use of regional anesthesiological procedures for abdominal wall and lower extremity blocks using selected blockages.

Abstract
Purpose A retrospective cohort study was performed to determine the effect of nerve block on the incidence of postoperative mortality in patients with hip replacement. Methods According to the inclusion and exclusion criteria, patients who were undergoing hip replacement for the first time under general or intraspinal anesthesia, classified as ASA class I-IV, and aged ≥65 years were selected. We collected the general data, past medical history, preoperative laboratory test results, perioperative fluid intake and outflow data, perioperative anesthesia and related drug data, postoperative laboratory results, and correlation time index. Patients with preoperative combined nerve block were included in the N group, and those without combined nerve block were included in the NN group. The patients were followed up via telephone call to assess survival outcomes at 3 years after surgery. Propensity score matching and uni- and multivariate analyses were performed to determine the influence of nerve block and other related factors on postoperative mortality. Results A total of 743 patients were included in this study, including 262 in the N group and 481 in the NN group. Two hundred five patients in both groups remained after propensity score matching. Main result: Preoperative nerve block was associated with reduced mortality three years after surgery. Conclusion Nerve block reduces the incidence of 3-year postoperative mortality, and composite nerve block with general anesthesia and neuraxial anesthesia is worthy of promotion.

Abstract
Regional nerve blocks (NBs) mitigate the occurrence of postoperative cognitive dysfunction (POCD) and postoperative delirium (POD) in adult patients undergoing thoracic surgery. This study aimed to determine the exact effect of NBs on POCD and POD. Electronic databases, including PubMed, EMBASE, CINAHL, Scopus, and Web of Science, were searched for studies. The primary outcome was the incidence of POD or POCD. The secondary outcome was pain scores assessed 24 and 48 h postoperatively. We calculated the log odds ratio (LOR) and standardized mean difference (SMD) with 95% confidence intervals (CIs). The LOR was converted to an odds ratio (OR). In the analysis of 1010 patients from seven randomized controlled trials, POD and POCD rates were 14.1% and 16.7%, respectively, in the NB group, and higher, at 27.3% and 35.2%, in the control group. NBs reduced the incidence of POD (OR, 0.44; 95%CI 0.30 to 0.64; p < 0.001; I2 = 0.00%) and POCD (OR, 0.43; 95%CI 0.24 to 0.76; p < 0.001; I2 = 0.00%). NBs reduced pain scores at 24 h (SMD, -2.60; 95%CI -3.90 to -1.30, p < 0.001; I2 = 97.68%) and 48 h (SMD, -1.80; 95%CI -3.18 to -0.41, p = 0.01; I2 = 98.14%) postoperatively. NBs mitigated the occurrence of POD and POCD in adult patients after thoracic surgery.

Front Aging Neurosci 2023; 15:1237001. [PMID: 37854033 PMCID: PMC10580806 DOI: 10.3389/fnagi.2023.1237001] [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: 06/08/2023] [Accepted: 08/28/2023] [Indexed: 10/20/2023] Open
Abstract
Objective To investigate whether paravertebral block reduces postoperative delirium (POD)/delayed neurocognitive recovery (DNR) in adults after major surgery with general anesthesia. Methods For this systematic review and meta-analysis, we searched online databases PubMed, EMBASE, CENTRAL, and Web of Science till March 19th, 2023 to examine studies which use paravertebral block (PVB) for perioperative neurocognitive disorder. Primary and secondary outcomes were identified for the incidence of perioperative neurocognitive disorder. We did not restrict the follow-up duration of the included studies. Statistical analysis was performed to calculate mean difference (MD), Odd ratios (OR) and CI between RCTs. The quality of the evidence was assessed with the Cochrane risk of bias tool. The registration number of the study in PROSPERO is CRD42023409502. PROSPERO is an international database of prospectively registered systematic reviews. Registration provides transparency in the review process and it helps counter publication bias. Results Total 1,225 patients from 9 RCTs were analyzed. The incidence of POD [Odds Ratio (OR) = 0.48, 95% CI 0.32, 0.72; p = 0.0004; I2 = 0%] and DNR [OR = 0.32, 95% CI 0.13, 0.80; p = 0.01; I2 = 0%] were significantly reduced in PVB group. The analysis showed no significant differences in postoperative MMSE scores [MD = 0.50, 95% CI -2.14, 3.15; p = 0.71; I2 = 98%]. Paravertebral block analgesia reduces pain scores and/or opioid use after surgery. Additionally, blood pressure was significantly lower in the PVB group, intraoperatively [MD = -15.50, 95% CI -20.71, -10.28; p < 0.001; I2 = 12%] and postoperatively [MD = -5.34, 95% CI -10.65, -0.03 p = 0.05; I2 = 36%]. Finally, PVB group had significantly shorter hospital stays [MD = -0.86, 95% CI -1.13, -0.59; p < 0.001; I2 = 0%]. Conclusion Paravertebral block analgesia may prevent perioperative POD/DNR in patients undergoing major surgery. Further research with large sample sizes is required to confirm its effectiveness.
