Efficacy and safety of ketamine wound infiltration for postoperative pain management: a systematic review, meta-analysis, and trial sequential analysis. Ann Med Surg (Lond) 2024; 86:6046-6061. [PMID: 39359791 PMCID: PMC11444560 DOI: 10.1097/ms9.0000000000002291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Accepted: 06/09/2024] [Indexed: 10/04/2024] Open
Abstract
Background Postoperative pain has a huge impact on the patients, families, healthcare practitioners, and healthcare delivery. Pain management with opioid-based analgesics and blind techniques have certain limitations, and ultrasound-based regional analgesia necessitates resources and experience, but ketamine wound infiltration is innovative with few side effects. However, its effectiveness is still uncertain. Methods A thorough search was carried out across various databases including PubMed/Medline, Cochrane, ScienceDirect, CINAHL, and LILACS, with no limitations on date or language. Only randomized trials comparing the effectiveness of ketamine wound infiltration for managing postoperative pain were considered for inclusion. Two authors independently conducted data extraction, and the quality of evidence was assessed using GRADEpro software. Trial sequential analysis (TSA) was utilized to ascertain the conclusiveness of the findings. Results The review showed that the first analgesic request was higher in the control group as compared to ketamine standard mean difference (SMD)=1.68 (95% CI: 0.95-2.41). The TSA revealed that the cumulative Z-curve crosses both alpha-spending boundaries and reaches the required information size threshold, revealing strong power for current evidence. However, the quality of evidence was moderate. Conclusion Despite available evidence, the provision of a firm conclusion is less optimal with current evidence as the included studies were unpowered with low to very low quality of evidence.

Abstract
INTRODUCTION Ultrasound-guided quadratus lumborum blocks are commonly used for postoperative analgesia during caesarean section. Ultrasound-guided quadratus lumborum blocks can be performed through four approaches, including lateral, posterior, anterior, and intramuscular quadratus lumborum blocks. This systematic review and meta-analysis aims to determine the optimal approach to ultrasound-guided quadratus lumborum blocks for postoperative analgesia in elective caesarean section. METHODS AND ANALYSIS The PubMed, EMBASE, Cochrane Library and Web of Science databases will be systematically searched from their inception to 30 July 2024. Randomised controlled trials that compared the analgesic effects of different ultrasound-guided quadratus lumborum block approaches in elective caesarean section will be included. Only publications in English will be eligible for inclusion. The total postoperative analgesic consumption over 24 hours will be the primary outcome. The time to first analgesic request, postoperative pain scores at rest and during movement, and incidence of adverse effects will be secondary outcomes. RevMan V.5.4 will be used for the statistical analysis. Network meta-analysis will be used for indirect comparisons between different approaches across studies. The Grading of Recommendations Assessment, Development and Evaluation approach will be used to assess the quality of evidence for each outcome. ETHICS AND DISSEMINATION Ethical approval was not required. The results of this study will be submitted to peer-reviewed journals. PROSPERO REGISTRATION NUMBER CRD42024503694.

Abstract
PURPOSE Investigate the analgesic efficacy of quadratus lumborum (QL) block versus transversus abdominis plane (TAP) block in postoperative pain management in nonemergent cesarean section. DESIGN Systematic review with meta-analysis. METHODS PubMed, Cochrane, CINAHL, Google Scholar, and gray literature were searched for evidence. Only randomized controlled trials examining the effects of QL and TAP block for nonemergent cesarean delivery were included. Mean difference (MD) was used to estimate continuous outcomes with appropriate effect models. The quality of evidence was rated using the Risk of Bias and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) system. FINDINGS Six studies involving 543 parturients were included. Compared to the TAP block, the cumulative 24-hour pain score at rest (MD, -0.60; 95% CI, -1.03 to -0.17; P = .007) and during activity (MD, -1.05; 95% CI, -1.54 to -0.56; P < .0001) were significantly lower in QL block. Time to the first analgesic rescue (MD, 21.67; 95% CI, -18.58 to 61.91; P = .29) and opioid consumption (MD, -1.96; 95% CI, -4.59 to 0.66; P = .14) were similar in both groups. No difference was found in the incidence of postoperative nausea and vomiting and sedation. However, patients treated with QL block reported higher patient satisfaction scores. CONCLUSIONS There is limited evidence to suggest that QL block is superior to TAP block for postoperative pain management in nonemergent cesarean delivery. The study limitations must be considered when extrapolating the review's findings to clinical practice.

Abstract
The opioid epidemic in the United States has led to an increasing number of pregnant patients with opioid use disorder (OUD) presenting to obstetric units. Caring for this complex patient population requires an interdisciplinary approach involving obstetricians, anesthesiologists, addiction medicine physicians, psychiatrists, and social workers. The management of acute pain in the parturient with OUD can be challenging due to several factors, including respiratory depression, opioid tolerance, and opioid-induced hyperalgesia. Patients with a history of OUD can present in one of three categories: 1) those with untreated OUD; 2) those who are currently abstinent from opioids; 3) those being treated with medications to prevent withdrawal. A patient-centered, multimodal approach is essential for optimal peripartum pain relief and prevention of adverse maternal and neonatal outcomes. Medications for opioid use disorder (MOUD), previously referred to as medication-assisted therapy (MAT), include opioids like methadone, buprenorphine, and naltrexone. These are prescribed for pregnant patients with OUD, but appropriate dosing and administration of these medications are critical to avoid withdrawal in the mother. Non-opioid analgesics such as acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) can be used in a stepwise approach, and regional techniques like neuraxial anesthesia and truncal blocks offer opioid-sparing options. Other medications like ketamine, clonidine, dexmedetomidine, nitrous oxide, and gabapentinoids show promise for pain management but require further research. Overall, a comprehensive pain management strategy is essential to ensure the well-being of both the mother and the fetus in pregnant patients with OUD.

[PMID: 38123185 PMCID: PMC10764215 DOI: 10.3344/kjp.23268] [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: 09/22/2023] [Revised: 11/22/2023] [Accepted: 12/04/2023] [Indexed: 12/23/2023] Open
Abstract
Background This study assessed the postoperative analgesic efficacy and safety of the quadratus lumborum block (QLB) in pediatric patients. Methods Electronic databases were searched for studies comparing the QLB to conventional analgesic techniques in pediatric patients. The primary outcome was the need for rescue analgesia 12 and 24 hours after surgery. Secondary outcomes covered the Face-Legs-Activity-Cry-Consolability Scale (FLACC) scores at various time points; parental satisfaction; time to the first rescue analgesia; hospitalization time; block execution time; block failure rates, and adverse events. Results Sixteen randomized controlled trials were analyzed involving 1,061 patients. The QLB significantly reduced the need for rescue analgesia both at 12 and 24 hours after surgery (12 hours, relative risk [RR]: 0.45; 95% confidence interval [CI]: 0.01, 0.88; 24 hours, RR: 0.51; 95% CI: 0.31, 0.70). In case of 24 hours after surgery, type 1 QLB significantly reduced the need for rescue analgesia (RR: 0.56; 95% CI: 0.36, 0.76). The QLB also exhibited lower FLACC scores at 1 hour (standardized mean difference [SMD]: -0.87; 95% CI: -1.56, -0.18) and 6 hours (SMD: -1.27; 95% CI: -2.33, -0.21) following surgery when compared to non-QLB. Among QLBs, type 2 QLB significantly extended the time until the first rescue analgesia (SMD: 1.25; 95% CI: 0.84, 1.67). No significant differences were observed in terms of parental satisfaction, hospitalization time, block execution time, block failure, or adverse events between QLB and non-QLB groups. Conclusions The QLB provides non-inferior analgesic efficacy and safety to conventional methods in pediatric patients.

Abstract
ESP block (ESPB) and posterior Quadratus Lumborum Block (pQLB) have been proposed as opioid-sparing techniques for the management of pain after abdominal surgery. Between December 2021 and October 2022, we conducted a retrospective comparative study at the delivery suite of Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome, Italy, to compare the efficacy of ESPB and pQLB in preventing postoperative pain after an elective caesarean section (CS). The primary outcome was total morphine consumption in the first 24 h. Secondary outcomes were time to first opioid request; Numerical Pain Rating Scale (NPRS) at 0, 2, 6, 12 and 24 h; vital signs; adverse events. Fifty-two women were included. The total cumulative dose of morphine was not significantly different between the two groups of patients (p = 0.897). Time to first dose of morphine, NPRS values and haemodynamic parameters were not statistically different between the two groups. NPRS values significantly increased (p < 0.001) at the different time intervals considered. The need for rescue doses of morphine was lower in the ESPB group compared to the pQLB group (hazard ratio of 0.51, 95% CI (0.27 to 0.95), p = 0.030). No adverse event was reported. ESPB seems to be as effective as pQLB in providing analgesia after CS.

Abstract
Background We aimed to compare the analgesic effect and quality of recovery of transmuscular quadratus lumborum block (QLB) and erector spinae plane block (ESPB) in the presence of multimodal analgesia following Caesarean section. Methods This randomised controlled trial included full-term pregnant women who underwent elective Caesarean section under spinal anaesthesia without intrathecal morphine. The included women were randomised to receive either bilateral QLB (n = 51) or bilateral thoracic ESPB (n = 51), in addition to the control group (n = 51) who did not receive any block. All participants received regular paracetamol (1 g/6h) and diclofenac (50 mg/8 h). Intravenous morphine was used as a rescue analgesic. The primary outcome was time to first morphine requirement. Secondary outcomes included total postoperative morphine consumption and total Obstetric Quality of Recovery-11 (ObsQoR-11) score. Results We analysed 51, 50 and 48 patients in the QLB, ESPB and control groups, respectively. The time to first morphine requirement in both QLB and ESPB groups was longer than that in the control group (median [quartiles] time: 6 [6,12] h, 6 [6,6] h and 4 [3,4] h, respectively; p-value <0.001), without significant differences between the two former groups. The total morphine consumption in both QLB and ESPB groups was lower than that in the control group (median [quartiles]:0 [0,5] mg, 0 [0,5] mg and 25 [25,30] mg, respectively; p-value <0.001), without significant differences between the two former groups. The QLB and ESPB groups had comparable ObsQoR-11 score, and both groups' scores were higher than the control group. Conclusion In patients undergoing elective Caesarean section under spinal anaesthesia without intrathecal morphine, both QLB and ESPB provided superior analgesia and quality of recovery compared to the standard care, without significant difference between the two blocks.

Abstract
BACKGROUND Quadratus lumborum and erector spinae plane blocks have been used to provide analgesia in patients undergoing thoracic or abdominal surgeries. Our study compared the analgesic efficacy of the quadratus lumborum type-II block (QLB-II) and the erector spinae plane block (ESPB) in parturients who underwent caesarean section under spinal anaesthesia. METHODS Fifty-two patients with comparable demographic profiles were randomised into two groups, QLB-II (n = 26) and ESPB (n = 26). After the surgery, patients received either ultrasound-guided QLB-II or ESPB using 0.25% bupivacaine 0.3 mL/kg. Comparison of analgesic efficacy was in terms of fentanyl consumption (primary outcome), pain scores, incidence of complications in the 24-h postoperative period, and quality of recovery (QoR-15) on postoperative days one and two, and day of discharge. RESULTS There was no significant difference in cumulative number of fentanyl doses (W = 349.000, P = 0.840), numerical rating score at rest (P = 0.648) or with movement (P = 0.520), QoR-15 scores on postoperative day one (P = 0.549), day two (P = 0.927) or day of discharge (P = 0.676). CONCLUSION We concluded that patients who underwent QLB-II or ESPB reported similar analgesic efficacy, complications, and quality of recovery in the postoperative period.

The minimum effective concentration (MEC90) of ropivacaine for ultrasound-guided quadratus lumborum block for analgesia after cesarean delivery: a dose finding study. BMC Anesthesiol 2022; 22:410. [PMID: 36581811 PMCID: PMC9798625 DOI: 10.1186/s12871-022-01954-5] [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: 10/31/2022] [Accepted: 12/21/2022] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND Quadratus lumborum block was recently proposed as an alternative technique for post-cesarean delivery analgesia. However, there is not a definite optimum concentration of local anesthetics. A biased coin design up-and-down method was used to explore the minimum effective concentration of ropivacaine in quadratus lumborum block for satisfactory analgesia after cesarean delivery. METHODS Fifty-six patients weighing 60-80 kg after cesarean section and with ages between 18 and 40 years were recruited. For the posterior quadratus lumborum block, a volume of 25 ml of the assigned concentration of ropivacaine was injected bilaterally. The concentration administered to each patient depended on the response to the previous dose. The first patient received 0.25%. If a successful block was observed, the next patient was randomized to receive the same ropivacaine concentration (with a probability of 0.89) or 0.025% less (with a probability of 0.11). After any block failure, the concentration was always increased by 0.025% for the next. The study ended when 45 successful blocks were obtained. We defined effective quadratus lumborum block as a resting visual analog score ≤ 3 and the absence of a need for rescue anesthetics. RESULTS The 90% minimum effective concentration of ropivacaine was 0.335% (95% CI 0.306 to 0.375%), and the 99% minimum effective concentration was 0.371% (95% CI 0.355 to 0.375%). The sufentanil consumption was 11 (11,13) and 24 (22,27) μg at 12 and 24 hours after quadratus lumborum block, respectively. CONCLUSIONS The optimum dosage of ropivacaine is a 25 ml volume of 0.335% for quadratus lumborum block after cesarean delivery. TRIAL REGISTRATION The study was registered in the Chinese Clinical Trial Registry (No. ChiCTR2000040415 ).

Abstract
BACKGROUND Postoperative pain after a cesarean section has negative consequences for the mother during the postoperative period. Over the years, various postoperative pain management strategies have been used following cesarean section. Opioid-based analgesics and landmark approaches have negative side effects, while ultrasound-based regional analgesia necessitates resources and experience, but various wound infiltration adjuvants are innovative with few side effects and are simple to use. The efficacy and safety of each adjuvant, however, are unknown and require further investigation. OBJECTIVE This network meta-analysis is intended to provide the most effective wound infiltration drugs for postoperative management after cesarean section. METHOD A comprehensive search will be conducted in PubMed/MEDLINE, Cochrane Library, Science Direct, CINHAL, and LILACS without date and language restrictions. All randomized trials comparing the effectiveness of wound infiltration drugs for postoperative pain management after cesarean section will be included. Data extraction will be conducted independently by two authors. The quality of studies will be evaluated using the Cochrane risk of bias tool, and the overall quality of the evidence will be determined by GRADEpro software. DISCUSSION The rate of postoperative acute and chronic pain is very high which has a huge impact on the mother, family, healthcare practitioners, and healthcare delivery. It is a basic human right to give every patient with postoperative pain treatment that is realistic in terms of resources, technique, cost, and adverse event profile.

Abstract
The purpose of this systematic review and network meta-analysis was to determine the analgesic effectiveness of peripheral nerve blocks (PNBs), including each anatomical approach, with or without intrathecal morphine (ITMP) in cesarean delivery (CD). All relevant randomized controlled trials comparing the analgesic effectiveness of PNBs with or without ITMP after CD until July 2021. The two co-primary outcomes were designated as (1) pain at rest 6 h after surgery and (2) postoperative cumulative 24-h morphine equivalent consumption. Secondary outcomes were the time to first analgesic request, pain at rest 24 h, and dynamic pain 6 and 24 h after surgery. Seventy-six studies (6278 women) were analyzed. The combined ilioinguinal nerve and anterior transversus abdominis plane (II-aTAP) block in conjunction with ITMP had the highest SUCRA (surface under the cumulative ranking curve) values for postoperative rest pain at 6 h (88.4%) and 24-h morphine consumption (99.4%). Additionally, ITMP, ilioinguinal-iliohypogastric nerve block in conjunction with ITMP, lateral TAP block, and wound infiltration (WI) or continuous infusion (WC) below the fascia also showed a significant reduction in two co-primary outcomes. Only the II-aTAP block had a statistically significant additional analgesic effect compared to ITMP alone on rest pain at 6 h after surgery (−7.60 (−12.49, −2.70)). In conclusion, combined II-aTAP block in conjunction with ITMP is the most effective post-cesarean analgesic strategy with lower rest pain at 6 h and cumulative 24-h morphine consumption. Using the six described analgesic strategies for postoperative pain management after CD is considered reasonable. Lateral TAP block, WI, and WC below the fascia may be useful alternatives in patients with a history of sensitivity or severe adverse effects to opioids or when the CD is conducted under general anesthesia.

Abstract
Optimal postoperative analgesia has a significant impact on patient recovery and outcomes after cesarean delivery. Multimodal analgesia is the core principle for cesarean delivery and pain management. For a standard analgesic regimen, the use of long-acting neuraxial opioids (e.g., morphine) and adjunct drugs, such as scheduled acetaminophen and nonsteroidal anti-inflammatory drugs, is recommended unless contraindicated. Oral or intravenous opioids should be reserved for breakthrough pain. In addition to the aforementioned use of multimodal analgesia, preoperative evaluation is critical to individualize the analgesic regimen according to the patient requirements. Risk factors for severe postoperative pain or analgesia-related adverse effects will require modifications to the standard analgesic regimen (e.g., the use of ketamine, gabapentinoids, or regional anesthetic techniques). Further investigation is required to determine analgesic drugs or dose alterations based on preoperative predictions for patients at risk of severe pain. Outcomes beyond pain and analgesic use, such as functional recovery, should be determined to evaluate analgesic treatment protocols.

Abstract
BACKGROUND Quadratus lumborum block (QLB) provides a reduction in pain scores and opioid consumption after cesarean section (CS). Intrathecal morphine (ITM) is still considered as the gold standard of acute postoperative pain therapy, but it does have some significant side effects. The aim of this clinical study was to evaluate whether performing the quadratus lumborum block type I in patients undergoing CS would be associated with an increased satisfaction of pain therapy and a decreased incidence of chronic postsurgical pain (CPSP). METHODS Sixty patients scheduled for elective CS were enrolled. All patients received spinal anesthesia and were randomly allocated to either the QLB group (received bilateral quadratus lumborum block type I with the use of 24 m mL 0.375% ropivacaine) or the control group (received no block). The level of satisfaction was evaluated using a three-step scale and the answers provided in a questionnaire regarding the patients' satisfaction with the method of postoperative pain treatment in the first 48 h. After a 6-month period, all patients were interviewed to evaluate the incidence and possible severity of CPSP. RESULTS Satisfaction scores were significantly lower in the QLB group than in the control group (p = 0.0000). There were no significant differences between the QLB and control groups regarding the occurrence of chronic postsurgical pain after 6 months following CS (p = 0.102). No statistical differences between the groups were recorded when we compared the results of the questionnaire after a period of 48 h from CS (the number of participants were limited in number). CONCLUSIONS QLB type I is an analgetic option that increased the satisfaction of parturients with pain therapy after CS compared to patients who did not receive the block, and there is a tendency for a lower incidence of CPSP.

Abstract
BACKGROUND Reducing pain and minimising the use of opioids after caesarean section are crucial to enhancing maternal recovery and promoting mother-newborn interaction. Various techniques have been implemented to improve analgesia. We compared the analgesic efficacy of posteromedial quadratus lumborum block with that of wound infiltration following elective caesarean section. OBJECTIVE We hypothesised that within a multimodal analgesia approach, posteromedial quadratus lumborum block would, due to its potential to relieve visceral pain, result in a 15% reduction in 24-h postoperative opioid consumption compared with wound infiltration. DESIGN A double-blind, randomised, placebo-controlled clinical study. SETTING A single-centre study between August 2019 and May 2020. PATIENTS One hundred and sixteen women were randomly allocated into two groups. In the quadratus lumborum group, 20 ml 0.9% saline was injected into the surgical wound followed by bilateral posteromedial quadratus lumborum block using 20 ml 0.25% levobupivacaine per side. In the wound infiltration group, 20 ml of 0.25% levobupivacaine was injected into the surgical wound followed by a bilateral posteromedial quadratus lumborum injection with 20 ml 0.9% saline per side. MAIN OUTCOME MEASURES The primary outcome was opioid (piritramide) consumption at 24 h. Secondary outcomes were piritramide consumption at 48 h, time-to-first analgesic request, pain scores at rest and with movement, surgery-to-first-ambulation time, surgery-to-breastfeeding time, sedation, pruritus and complications. RESULTS Piritramide consumption in 24 h was significantly lower with posteromedial quadratus lumborum block (1.5 ± 1.8 mg) than with wound infiltration (2.2 ± 1.7 mg) (P = 0.04), mean difference of -0.7 mg, (95% CI -1.3 to -0.03). In those who required piritramide, time-to-first analgesic request was significantly longer with posteromedial quadratus lumborum block 11 [7 to 14] h, than with wound infiltration 7 [5 to 11] h (P = 0.02). Pain scores were low, with no differences recorded at rest and with movement. There were no differences in time-to-ambulation and time-to-breastfeed between the groups. CONCLUSION As a component of multimodal post-caesarean section analgesia, posteromedial quadratus lumborum block was associated with lower 24-h opioid consumption compared with wound infiltration.

Abstract
Fascial plane blocks (FPBs) are increasingly numerous and are often touted as effective solutions to many perioperative challenges facing anesthesiologists. As 'new' FPBs are being described, questions regarding their effectiveness remain unanswered as appropriate studies are lacking and publications are often limited to case discussions or technical reports. It is often unclear if newly named FPBs truly represent a novel intervention with new indications, or if these new publications describe mere ultrasound facilitated modifications of existing techniques. Here, we present broad concepts and potential mechanisms of FPB. In addition, we discuss major FPBs of (1) the extremities (2) the posterior torso and (3) the anterior torso. The characteristics, indications and a brief summary of the literature on these blocks is included. Finally, we provide an estimate of the overall level of evidence currently supporting individual approaches as FPBs continue to rapidly evolve.

Abstract
Objective Cesarean section (CS) is one of the most frequently performed major surgical interventions. Local anesthetic techniques, a universal component of perioperative multimodal analgesia, are reportedly effective in reducing pain scores and opioid requirements. However, the optimal local anesthetic technique for postoperative CS pain remains unclear. Methods Six databases were searched, and a Bayesian network meta-analysis was performed. The outcomes included cumulative morphine consumption and pain scores at four time points, time to first analgesic request, postoperative nausea and vomiting, pruritus, and sedation. Results Sixty-eight studies with 5039 pregnant women were included. Six local anesthetic techniques were involved, including transversus abdominis plane block (TAPB), ilioinguinal and iliohypogastric nerve block, quadratus lumborum blocks, transversalis fascia plane block, erector spinae block, and wound infiltration. Compared to inactive controls, TAPB reduced cumulative morphine consumption at 6, 12, 24, and 48 h, pain scores at 6, 12, and 24 h (with the exception of 24 h at rest), the risk of postoperative nausea and vomiting, and sedation. Compared with inactive controls, ilioinguinal and iliohypogastric nerve block reduced cumulative morphine consumption at 6 and 24 h and pain scores at 6, 12, and 24 h during movement. Compared with inactive controls, quadratus lumborum blocks reduced cumulative morphine consumption at 24 and 48 h and pain scores at 6 and 12 h and lengthened the time to first analgesic request. Compared with inactive controls, wound infiltration reduced cumulative morphine consumption at 12 and 24 h, pain scores at 12 and 24 h during movement, and risk of sedation. Compared with inactive controls, erector spinae block reduced pain scores at 6 and 12 h. Transversalis fascia plane block was found to have similar outcomes to inactive controls. Conclusion TAPB is the most comprehensive local anesthetic technique for postoperative CS analgesia in the absence of intrathecal morphine.

Abstract
BACKGROUND Postoperative pain after abdominoplasty can delay postoperative ambulation, leading to life-threatening complications. Previous reports have shown the utility of quadratus lumborum block in providing adequate pain relief and avoiding side effects after numerous abdominal operations. The purpose of this randomized controlled trial was to demonstrate the efficacy of the quadratus lumborum block in abdominoplasty. METHODS Patients were randomly allocated to receive a bilateral quadratus lumborum block with either ropivacaine or normal saline. Postoperative cumulative analgesic medication consumption, pain severity at rest and on movement, and quality of recovery were evaluated and compared in both groups. RESULTS Twenty patients were allocated to each group. Total morphine dose received in the postanesthesia care unit was lower in the ropivacaine group than in the control group, with a mean of 3.4 mg and 6.6 mg, respectively. Cumulative tramadol consumption per patient in the first 48 hours postoperatively was significantly lower in the ropivacaine group compared with the control group (42.5 mg versus 190 mg; p = 0.0031). The Numeric Rating Scale both at rest and with effort was significantly lower in the ropivacaine group compared with the control group. The median quality of recovery for the ropivacaine group was 133 compared with 112 for the control group (p < 0.0001). CONCLUSIONS Quadratus lumborum block in abdominoplasty reduces postoperative pain and opioid consumption and improves the quality of recovery. Further studies are needed to compare the quadratus lumborum block to more traditional blocks. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, II.

Abstract
BACKGROUND Ultrasound-guided quadratus lumborum block (QLB) is a truncal block with several technique variations. It has been reported as providing effective analgesia for postoperative pain. OBJECTIVES The aim of this review was to evaluate the efficacy and safety of QLB for postoperative analgesia. The primary outcome was cumulative opioid consumption at 24 h postoperatively. The main secondary outcomes were the time to the first rescue opioid analgesic, pain scores at 24 h postoperatively and the incidence of postoperative nausea and vomiting (PONV). DESIGN This was a systematic review and meta-analyses of observational studies and randomised controlled trials (RCTs). PRISMA-P guidelines were followed, and the review was registered in PROSPERO. GRADE was used to assess the quality of evidence. DATA SOURCES The search was performed from several databases (Ovid MEDLINE, PubMed, Scopus, Web of Science, CINAHL and the Cochrane CENTRAL) from inception up to June 2019. ELIGIBILITY CRITERIA RCTs and prospective observational studies that investigated the postoperative analgesic properties of US-guided single shot QLB in adult patients undergoing abdominal or hip surgery were included. QLB was compared with other analgesics. RESULTS Twenty-seven studies constituting 1557 patients were reviewed. Twelve studies with 803 patients were included in the meta-analysis on the primary outcome. Overall opioid consumption at 24 h postoperatively was reduced [mean difference, -11.15 (95% CI, -15.33 to -6.97) mg, I2 = 99%, moderate certainty in GRADE] and the time to the first opioid analgesic was longer in patients with QLB: 7 studies with 499 patients, mean difference, 189.32 (95% CI, 114.4 to 264.23) min, I2 = 98%. There were no differences in pain grades. The incidence of PONV was lower in patients with QLB [11 studies with 744 patients, OR 0.40 (95% CI, 0.27 to 0.58), I2 = 7%]. Reported complications and adverse effects of QLB were minimal. CONCLUSION QLB reduced postoperative opioid consumption, prolonged the time to the first rescue opioid analgesic and diminished the incidence of PONV. QLB appears to be an applicable option for postoperative analgesia after abdominal and hip surgery. REGISTRATION NUMBER PROSPERO, https://www.crd.york.ac.uk/prospero/, CRD42016039921.

Abstract
This narrative review discusses recent evidence surrounding the use of regional anaesthesia in the obstetric setting, including intrapartum techniques for labour and operative vaginal delivery, and caesarean delivery. Pudendal nerve blockade, ideally administered by an obstetrician, should be considered for operative vaginal delivery if neuraxial analgesia is contraindicated. Regional techniques are increasingly utilised in clinical practice for caesarean delivery to minimise opioid consumption, reduce pain, improve postpartum recovery and facilitate earlier discharge as part of enhanced recovery protocols. The evidence surrounding transversus abdominis plane and quadratus lumborum blockade supports their use when: long-acting neuraxial opioids cannot be administered due to contraindications; if emergency delivery necessitates general anaesthesia; or as a postoperative rescue technique. Current data suggest quadratus lumborum blockade is no more effective than transversus abdominis plane blockade after caesarean delivery. Transversus abdominis plane blockade, wound catheter insertion and single shot wound infiltration are all effective techniques for reducing postoperative opioid consumption, with transversus abdominis plane blockade favoured, followed by wound catheters and then wound infiltration. Ilio-inguinal and iliohypogastric, erector spinae plane and rectus sheath blockade all require further studies to determine their efficacy for caesarean delivery in the presence or absence of long-acting neuraxial opioids. Future studies are needed to: compare approaches for individual techniques; determine which combinations of techniques and dosing regimens result in optimal analgesic and recovery outcomes following delivery; and elucidate the populations that benefit most from regional anaesthesia in the obstetric setting.

Abstract
Rebound pain after regional anesthesia can be defined as transient acute postoperative pain that ensues following resolution of sensory blockade, and is clinically significant, either with regard to the intensity of pain or the impact on psychological well-being, quality of recovery, and activities of daily living. Current evidence suggests that it represents an unmasking of the expected nociceptive response in the absence of adequate systemic analgesia, rather than an exaggerated hyperalgesic phenomenon induced by local anesthetic neural blockade. In the majority of patients, it does not appear to significantly impact cumulative postoperative opioid consumption, quality of recovery, or patient satisfaction, and is not associated with longer-term sequelae such as persistent post-surgical pain. Nevertheless, it must be considered whenever regional anesthesia is incorporated into perioperative management. Strategies to mitigate the impact of rebound pain include routine prescribing of a systemic multimodal analgesic regimen, as well as patient education on appropriate expectations regarding block offset and expected surgical pain, and timely initiation of analgesic medication. Prolonging the duration of action of regional anesthesia with continuous catheter techniques or local anesthetic adjuncts may also help alleviate rebound pain, although further research is required to confirm this.

The effectiveness of the intramuscular quadratus lumborum block in postoperative analgesia after cesarean section with vertical incision: a randomized, double-blinded placebo-controlled study. J Anesth 2020; 34:849-856. [PMID: 32691228 DOI: 10.1007/s00540-020-02829-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 07/13/2020] [Indexed: 01/18/2023]
Abstract
PURPOSE Quadratus lumborum block (QLB) has recently been used for postoperative analgesia after abdominal surgery. Although there are several approaches to QLB, the effectiveness of intramuscular QLB (QLBi) remains controversial. The aim of the present study was to examine the effectiveness of QLBi for postoperative analgesia after cesarean section with a vertical midline incision. METHODS In this single-center, randomized, double-blinded placebo-controlled study, 36 women who were scheduled for elective cesarean section were randomly divided into a QLBi group (n = 18) and a placebo group (n = 18). In both groups, spinal anesthesia was performed with 10-11 mg hyperbaric bupivacaine and 15 µg fentanyl. After the surgery, in the QLBi group, 0.4 mL/kg of 0.25% ropivacaine was injected into the bilateral quadratus lumborum muscle under ultrasound guidance (the total volume was 0.8 mL/kg). In the placebo group, instead of ropivacaine, the subjects were injected with the same amount of normal saline. The primary outcome measure was elapsed time to first analgesic use from the QLBi block after cesarean section. RESULTS The data from all 36 patients were analyzed. There were no significant differences between the QLBi and placebo groups regarding elapsed time to first postoperative analgesic use [mean 230 (standard deviation 103) vs 194 (89) min; 95% confidence interval - 101 to 30; p = 0.27]. CONCLUSIONS QLBi with the concentration and amount of local anesthetic used in the present study was clinically slightly effective, and the effect was limited for postoperative analgesia after cesarean section.

Abstract
Intraoperative and postoperative nausea and vomiting (IONV and PONV) afflict up to 80% of parturients undergoing cesarean delivery with neuraxial anesthesia. Preventing nausea and emesis is a top priority for women undergoing cesarean delivery and is included in the quality of recovery measures and enhanced recovery after cesarean delivery protocols. The majority of known perioperative emetic triggers can be avoided or mitigated by optimizing anesthetic and surgical management. IONV may arise from spinal anesthesia-induced hypotension, intraoperative pain, and medications such as uterotonics and antibiotics. Furthermore, uterine exteriorization and peritoneal irrigation increase IONV risk. Conversely, preventing PONV mainly focuses on optimizing analgesia through an opioid-sparing, multimodal strategy. In addition, combination prophylactic antiemetic therapy should be instituted in this high-risk population to further reduce the risk of IONV and PONV.
