Popliteal sciatic nerve block for high-risk patients undergoing lower limb angioplasty: A prospective double-blinded randomized controlled trial. Medicine (Baltimore) 2023; 102:e33690. [PMID: 37145010 PMCID: PMC10158915 DOI: 10.1097/md.0000000000033690] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 04/13/2023] [Indexed: 05/06/2023] Open
Abstract
BACKGROUND To assess the rate of conversion to general anesthesia, sedative and analgesic drug-sparing effects, and complications of popliteal sciatic nerve block (PSNB) compared with a sham block during lower limb angioplasty. METHODS A randomized, controlled, double-blinded trial of patients with chronic limb-threatening ischemia (CLTI) who receive PSNB with 0.25% levobupivacaine 20 mL compared with a sham block (control) during lower limb angioplasty. Pain scores, conversion rate to general anesthesia, amount of sedoanalgesia drug usage, complications, and satisfaction with the anesthesia technique by surgeons and patients were assessed. RESULTS Forty patients were enrolled in this study. Two of 20 (10%) control group patients were converted to general anesthesia, while none of the patients in the intervention group required general anesthesia (P = .487). Pain scores before PSNB did not differ between the groups (P = .771). After the block, pain scores in the block group were lower than those in the control group: 0 (0, 1.5) (median, interquartile range) and 2.5 (0.5, 3.5), respectively (P = .024). The analgesic effect persisted until immediately after the surgery (P = .035). There was no difference in pain scores at the 24-hours follow-up visit (P = .270). The total propofol and fentanyl dosage requirements, a number of patients who required propofol and fentanyl, side effects, and satisfaction were not different between the groups. No major complications were noted. CONCLUSIONS PSNB provided effective pain relief during and immediately after lower limb angioplasty, but did not statistically affect the rate of conversion to general anesthesia, sedoanalgesia drug usage, or complications.

Outcomes After Neuraxial or Regional Anaesthesia Instead of General Anaesthesia for Lower Limb Revascularisation Surgery: A Systematic Review and Meta-Analysis of Randomised and Non-Randomised Studies. Eur J Vasc Endovasc Surg 2023; 65:379-390. [PMID: 36336286 DOI: 10.1016/j.ejvs.2022.10.046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 10/19/2022] [Accepted: 10/30/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To determine whether receipt of neuraxial or regional anaesthesia instead of general anaesthesia for lower limb revascularisation surgery affects patient outcomes. DATA SOURCES MEDLINE, EMBASE, Evidence Based Medicine Reviews, and Google Scholar. REVIEW METHODS After protocol registration, the data sources were searched for randomised and non-randomised studies comparing neuraxial or regional anaesthesia with general anaesthesia for lower limb revascularisation surgery in adults. Two investigators independently selected articles, extracted data, and assessed risks of bias. Data were pooled using random effects models. GRADE was used to assess certainty in cumulative evidence. RESULTS From 10 755 citations identified, five randomised (n = 970) and 13 non-randomised (n = 96 800) studies were included. Use of neuraxial instead of general anaesthesia for lower limb revascularisation surgery was associated with no statistically significant reduction in short term (in hospital or 30 day) mortality in randomised studies (pooled odds ratio [OR] 0.77; 95% confidence interval [CI] 0.33 - 1.81; low certainty) and a statistically significant reduction in adjusted short term mortality in non-randomised studies (pooled OR 0.67; 95% CI 0.56 - 0.81; low certainty). Adults allocated to neuraxial anaesthesia in randomised studies had fewer pulmonary complications (pooled OR 0.35; 95% CI 0.16 - 0.76; low certainty). In non-randomised studies, neuraxial instead of general anaesthesia was associated with a lower adjusted odds of any morbidity (pooled OR 0.66; 95% CI 0.52 - 0.84), cardiac complications (pooled OR 0.68; 95% CI 0.58 - 0.79), pneumonia (pooled OR 0.81; 95% CI 0.64 - 1.02), prolonged mechanical ventilation (OR 0.09; 95% CI 0.002 - 0.55), and bypass graft thrombosis (OR 0.70; 95% CI 0.59 - 0.85), as well as a shorter operative duration (low certainty for all). Use of a nerve block instead of general anaesthesia was associated with a lower adjusted odds of delirium (OR 0.16; 95% CI 0.06 - 0.42) and a shorter operative duration (low certainty for both). CONCLUSION Randomised and non-randomised data suggest that neuraxial anaesthesia for lower limb revascularisation surgery reduces morbidity and possibly mortality. Until randomised trials with a low risk of bias become available, this study supports use of neuraxial anaesthesia for these procedures where appropriate.

Racial Disparities in the Use of Peripheral Nerve Blocks for Postoperative Analgesia After Total Mastectomy: A Retrospective Cohort Study. Anesth Analg 2022; 135:170-177.

Abstract
BACKGROUND Peripheral nerve blocks (PNBs) are used to provide postoperative analgesia after total mastectomy. PNBs improve patient satisfaction and decrease postoperative opioid use, nausea, and vomiting. Few studies have examined whether there is racial-ethnic disparity in the use of PNBs for patients having total mastectomy. We hypothesized that non-Hispanic Asian, non-Hispanic Black, non-Hispanic patients of other races, and Hispanic patients would be less likely to receive a PNB for postoperative analgesia compared to non-Hispanic White patients having total mastectomy. Secondarily, we hypothesized that PNBs would be associated with reduced odds of major complications after total mastectomy. METHODS We performed a retrospective cohort study using National Surgical Quality Improvement Program (NSQIP) data from 2015 to 2019. Patients were included if they underwent total mastectomy under general anesthesia. Unadjusted rates of PNB use were compared between race-ethnicity groups. Multivariable logistic regression was performed to determine whether race-ethnicity group was independently associated with receipt of a PNB for postoperative analgesia. Secondarily, we calculated crude and risk-adjusted odds ratios for major complications in patients who received a PNB. RESULTS There were 64,103 patients who underwent total mastectomy and 4704 (7.3%) received a PNB for postoperative analgesia. Patients who received a PNB were younger, more commonly women, were less likely to have diabetes and hypertension, and had less disseminated cancer (all P < .05). In our regression analysis, the odds of receiving a PNB differed significantly by race-ethnicity group (P < .001). Non-Hispanic Asian and non-Hispanic Black patients had reduced odds of receiving a PNB compared to non-Hispanic White patients (odds ratio [OR], 0.41; 95% confidence interval [CI], 0.33-0.49 and OR, 0.37 [0.32-0.44]), respectively. Non-Hispanic patients of other races, including American Indian, Alaskan Native, and Pacific Islander, also had reduced odds of receiving a PNB (OR, 0.73 [95% CI, 0.64-0.84]) compared to non-Hispanic White patients, as did Hispanic patients (OR, 0.62 [0.56-0.69]). Patients who received a PNB did not have reduced odds of major complications after mastectomy (crude OR, 0.83 [0.65-1.08]; P = .17 and adjusted OR, 0.85 [0.65-1.10]; P = .21). CONCLUSIONS Significant disparity exists in the use of PNBs for postoperative analgesia in patients of different race-ethnicity who undergo total mastectomy in the United States. Continued efforts are needed to better understand the causes of disparity and to ensure equitable access to PNBs.

Abstract
Background The relationship between anaesthetic technique and graft patency after open lower limb revascularization is unclear. The aim of this study was to evaluate the association between 30-day graft patency after elective infrainguinal bypass and anaesthetic technique (regional anaesthesia (RA, i.e. neuraxial and/or peripheral nerve blockade) compared with general anaesthesia (GA)). Methods Patients who underwent elective infrainguinal bypass in the 2014–2019 National Surgical Quality Improvement Program Vascular Procedure Targeted Lower Extremity Open data set were included. Excluded patients were those under 18 years old, those who did not receive RA or GA, and/or had an international normalized ratio of 1.5 of greater, a partial thromboplastin time more than 35 s, or a platelet count less than 80 × 109/L. The primary outcome was primary graft patency without reintervention. The relationship between anaesthetic technique and patency was analysed with multivariable logistic regression. Results Included were 8893 patients with a mean(s.d.) age of 68(11) years and 31.5 per cent female. Within the cohort, 7.7 per cent (n = 688) patients received RA only, 90.4 per cent (n = 8039) GA only, and 1.9 per cent (n = 166) both GA and RA. In the RA-only group, 91.7 per cent (631 of 688) received neuraxial anaesthesia. The primary patency rate was 93.2 per cent (573 of 615) for RA only, and 91.5 per cent (6390 of 6983) for GA only (standardized mean difference, 0.063). RA was not associated with a higher rate of patency compared with GA (adjusted OR, 1.16; 95 per cent c.i., 0.83 to 1.63; P = 0.378). Conclusion There was no association between anaesthetic technique and 30-day graft patency after elective infrainguinal bypass surgery. Further prospective studies would be useful to study the impact of anaesthesia technique on important patient-centred outcomes such as long-term patency and non-home discharge.

Abstract
PURPOSE To evaluate the ability of subgluteal sciatic nerve block (SSNB) to provide pain control during endovascular treatment of below-the-knee (BTK) occlusions. MATERIALS AND METHODS This randomized prospective controlled study evaluated 60 consecutive adult patients who underwent endovascular treatment for BTK occlusions. The patients were randomized into 2 equal groups; the SSNB group underwent SSNB in the subgluteal space under ultrasound guidance, while the control group received fentanyl as an analgesic. The visual analog scale (VAS) and Face, Legs, Activity, Cry, Consolability (FLACC) scale scores were recorded. RESULTS Compared with the control group, the SSNB group showed significantly lower median VAS (0 [range, 0-30] vs 70 [range, 20-100], P < .001) and median FLACC scale (0 [range, 0-2] vs 6 [range, 3-10], P < .001) scores. There was no statistically significant difference between the 2 groups regarding the remaining parameters. There was a very strong correlation between the VAS and FLACC scale scores in both the SSNB (r = 0.805, P < .001) and control (r = 0.950, P < .001) groups. The procedure time and total balloon inflation time correlated with the VAS (r = 0.411, P = .024, and r = 0.402, P = .031, respectively) and FLACC scale (r = 0.431, P = .017, and r = 0.414, P = .022, respectively) scores in the control group but not in the SSNB group (r = 0.364, P = .056, and r = 0.300, P =.085, respectively, for correlation with VAS score and r = 0.730, P = .068, and r = 0.704, P = .075, respectively, for correlation with the FLACC scale score). CONCLUSIONS SSNB is a highly effective and safe pain management modality for the endovascular treatment of BTK occlusions.
