RESUMEN
Laparoscopic cholecystectomy can be associated with significant postoperative pain that is difficult to treat. We aimed to evaluate the available literature and develop updated recommendations for optimal pain management after laparoscopic cholecystectomy. A systematic review was performed using the procedure-specific postoperative pain management (PROSPECT) methodology. Randomised controlled trials and systematic reviews published in the English language from August 2017 to December 2022 assessing postoperative pain after laparoscopic cholecystectomy using analgesic, anaesthetic or surgical interventions were identified from MEDLINE, Embase and Cochrane Databases. From 589 full text articles, 157 randomised controlled trials and 31 systematic reviews met the inclusion criteria. Paracetamol combined with NSAIDs or cyclo-oxygenase-2 inhibitors should be given either pre-operatively or intra-operatively, unless contraindicated. In addition, intra-operative intravenous (i.v.) dexamethasone, port-site wound infiltration or intraperitoneal local anaesthetic instillation are recommended, with opioids used for rescue analgesia. As a second-line regional technique, the erector spinae plane block or transversus abdominis plane block may be reserved for patients with a heightened risk of postoperative pain. Three-port laparoscopy, a low-pressure pneumoperitoneum, umbilical port extraction, active aspiration of the pneumoperitoneum and saline irrigation are recommended technical aspects of the operative procedure. The following interventions are not recommended due to limited or no evidence on improved pain scores: single port or mini-port techniques, routine drainage, low flow insufflation, natural orifice transluminal endoscopic surgery (NOTES), infra-umbilical incision, i.v. clonidine, nefopam and regional techniques such as quadratus lumborum block or rectus sheath block. Several interventions provided better pain scores but are not recommended due to risk of side effects: spinal or epidural anaesthesia, gabapentinoids, i.v. lidocaine, i.v. ketamine and i.v. dexmedetomidine.

OBJECTIVE: To quantify the association between prophylactic radiologic interventions and perioperative blood loss during cesarean delivery in women with placenta accreta spectrum disorder through a systematic review and network meta-analysis. DATA SOURCES: On January 3, 2023, a literature search was conducted in PubMed, EMBASE, Cochrane Library, and Web of Science. We also checked ClinicalTrials.gov retrospectively. Prophylactic radiologic interventions to reduce bleeding during cesarean delivery involved preoperative placement of balloon catheters, distal (internal or common iliac arteries) or proximal (abdominal aorta), or sheaths (uterine arteries). The primary outcome was volume of blood loss; secondary outcomes were the number of red blood cell units transfused and adverse events. Studies including women who received an emergency cesarean delivery were excluded. METHODS OF STUDY SELECTION: Two authors independently screened citations for relevance, extracted data, and assessed the risk of bias of individual studies with the Cochrane Risk of Bias in Non-randomized Studies of Interventions tool. TABULTATION, INTEGRATION, AND RESULTS: From a total of 1,332 screened studies, 50 were included in the final analysis, comprising 5,962 women. These studies consisted of two randomized controlled trials and 48 observational studies. Thirty studies compared distal balloon occlusion with a control group, with a mean difference in blood loss of -406 mL (95% CI, -645 to -167). Fourteen studies compared proximal balloon occlusion with a control group, with a mean difference of -1,041 mL (95% CI, -1,371 to -710). Sensitivity analysis excluding studies with serious or critical risk of bias provided similar results. Five studies compared uterine artery embolization with a control group, all with serious or critical risk of bias; the mean difference was -936 mL (95% CI, -1,522 to -350). Reported information on adverse events was limited. CONCLUSION: Although the predominance of observational studies in the included literature warrants caution in interpreting the findings of this meta-analysis, our findings suggest that prophylactic placement of balloon catheters or sheaths before planned cesarean delivery in women with placenta accreta spectrum disorder may, in some cases, substantially reduce perioperative blood loss. Further study is required to quantify the efficacy according to various severities of placenta accreta spectrum disorder and the associated safety of these radiologic interventions.

This review aims to assess the published evidence on airway management with a supraglottic airway device (SGA) for general anaesthesia in patients requiring a caesarean section. Physiological changes during pregnancy can make airway management in parturients challenging. At the same time, pregnant patients are at risk of pulmonary aspiration due to hormonal and mechanical alterations. The standard airway management for parturients undergoing caesarean section is rapid sequence induction followed by tracheal intubation. Evidence exists that using second-generation SGA devices is well tolerated and effective in selected patients. In this review, we provide an overview of the existing evidence and provide an algorithm to make an evidence-based clinical decision on the use of SGA devices. An online literature search was performed in Medline, Embase, PubMed, Emcare, Cochrane Library and CINAHL. The search terms used were 'supraglottic airway', 'supraglottic airway device', 'supraglottic airway management', 'supraglottic tube', 'i-gel', laryngeal mask', 'laryngeal mask airway', 'LMA', 'SGA', 'Proseal', 'Supreme', 'obstetric surgery', 'obstetric operation', 'general anaesthesia', 'caesarean' or 'caesarean section', 'abdominal delivery'. Full-text articles in English, Dutch and French were included. Case reports and studies in which the surgery was not a caesarean section were excluded. The initial search yielded 815 results. Following screening, deduplication and removal of publications that were unrelated to the topic or did not fit the inclusion criteria, 13 manuscripts were included in our analysis. A total of 7722 patients were described in the articles included. In the majority of manuscripts, second-generation SGA devices were used. There were seven cases of failed insertion and a need for conversion to tracheal intubation; first-generation SGA devices were used in these cases. There were no cases of pulmonary aspiration, and only one case of gastric regurgitation was described. Growing evidence suggests that the use of second-generation SGA devices might be well tolerated as the primary method for securing the airway for caesarean sections requiring general anaesthesia, in selected patients with a low risk for aspiration and difficult intubation.

Background: Several regional anesthesia (RA) techniques have been described for distal upper limb surgery. However, the best approach in terms of RA block success rate and safety is not well recognized. Objective: To assess and compare the surgical anesthesia and efficacy of axillary brachial plexus block with other RA techniques for hand and wrist surgery. The attainment of adequate surgical anesthesia 30 min after block placement was considered a primary outcome measure. Additionally, successful block outcomes were required without the use of supplemental local anesthetic injection, systemic opioid analgesia, or the need to convert to general anesthesia. Methods: We performed a systematic search in the following databases: MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, and CENTRAL. RCTs comparing axillary blocks with other brachial plexus block techniques, distal peripheral forearm nerve block, intravenous RA, and the wide-awake local anesthesia no tourniquet (WALANT) technique were included. Results: In total, 3070 records were reviewed, of which 28 met the inclusion criteria. The meta-analysis of adequate surgical anesthesia showed no significant difference between ultrasound-guided axillary block and supraclavicular block (RR: 0.94 [0.89, 1.00]; p = 0.06; I2 = 60.00%), but a statistically significant difference between ultrasound-guided axillary block and infraclavicular block (RR: 0.92 [0.88, 0.97]; p < 0.01; I2 = 53.00%). Ultrasound-guided infraclavicular blocks were performed faster than ultrasound-guided axillary blocks (SMD: 0.74 [0.30, 1.17]; p < 0.001; I2 = 85.00%). No differences in performance time between ultrasound-guided axillary and supraclavicular blocks were demonstrated. Additionally, adequate surgical anesthesia onset time was not significantly different between ultrasound-guided block approaches: ultrasound-guided axillary blocks versus ultrasound-guided supraclavicular blocks (SMD: 0.52 [-0.14, 1.17]; p = 0.12; I2 = 86.00%); ultrasound-guided axillary blocks versus ultrasound-guided infraclavicular blocks (SMD: 0.21 [-0.49, 0.91]; p = 0.55; I2 = 92.00%). Conclusions: The RA choice should be individualized depending on the patient, procedure, and operator-specific parameters. Compared to ultrasound-guided supraclavicular and infraclavicular block, ultrasound-guided axillary block may be preferred for patients with significant concerns of block-related side effects/complications. High heterogeneity between studies shows the need for more robust RCTs.
RESUMEN
BACKGROUND: A vaginal delivery may be associated with acute postpartum pain, particularly after perineal trauma. However, pain management in this setting remains poorly explored. OBJECTIVE: The aim of this systematic review was to evaluate the literature and to develop recommendations for pain management after a vaginal delivery with perineal trauma. EVIDENCE REVIEW: MEDLINE, Embase, and Cochrane databases were searched for randomized controlled trials (RCTs) and systematic reviews assessing pain after a vaginal delivery with perineal tears or episiotomy until March 2023. Cochrane Covidence quality assessment generic tool and the RoB Vis 2 tool were used to grade the quality of evidence. FINDINGS: Overall, 79 studies (69 RCTs and 10 systematic reviews and meta-analyses) of good quality of evidence were included. Acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as first-line treatment. Epidural morphine (≤2 mg) is recommended among women with labor epidural analgesia and severe perineal tears, with adequate respiratory monitoring. Local anesthetic infiltration, topical local anesthetic, ointment application, and pudendal nerve block are not recommended due to insufficient or lack of evidence. Ice or chemical cold packs are recommended for postpartum pain first-line treatment due to their simplicity of use. Transcutaneous nerve stimulation and acupuncture are recommended as adjuvants. When a perineal suture is indicated, a continuous suture compared with an interrupted suture for the repair of episiotomy or second-degree perineal tears is recommended for the outcome of pain. For women with first-degree or second-degree perineal tears, no suturing or glue compared with suturing is recommended for the outcome of pain. CONCLUSIONS: Postpartum pain management after a vaginal delivery with perineal trauma should include acetaminophen, NSAIDs, and ice or chemical cold packs. Epidural morphine should be reserved for severe perineal tears. A surgical repair technique should depend on perineal tear severity.
RESUMEN
BACKGROUND: Open colectomy is still performed around the world and associated with significant postoperative pain. OBJECTIVES: Unpublished recommendations based on a systematic review were proposed by the PROcedure SPECific postoperative pain managemenT (PROSPECT) group in 2016. We aimed to update these recommendations by evaluating the available literature and develop recommendations for optimal pain management after open colectomy according to the PROSPECT methodology. DESIGN AND DATA SOURCES: A systematic review using the PROSPECT methodology was undertaken. Randomised controlled trials and systematic reviews published in the English language from 2016 to 2022 assessing postoperative pain after open colectomy using analgesic, anaesthetic or surgical interventions were identified. The primary outcome included postoperative pain scores. RESULTS: The previous 2016 review included data from 93 studies. Out of 842 additional eligible studies identified, 13 new studies were finally retrieved for analysis. Intra-operative and postoperative interventions that improved postoperative pain were paracetamol, epidural analgesia. When epidural is not feasible, intravenous lidocaine or bilateral TAP block or postoperative continuous pre-peritoneal infusion are recommended. Intra-operative and postoperative Cyclo-oxygenase (COX)-2 specific-inhibitors or non-steroidal anti-inflammatory drugs (NSAIDs) are recommended for colonic surgery. CONCLUSIONS: The analgesic regimen for open colectomy should include intra-operative paracetamol and COX-2 specific inhibitors or NSAIDs (restricted to colonic surgery), epidural and continued postoperatively with opioids used as rescue analgesics. If epidural is not feasible, bilateral TAP block or IV lidocaine are recommended. Safety issues should be highlighted: local anaesthetics should not be administered by two different routes at the same time. Because of the risk of toxicity, careful dosing and monitoring are necessary.

STUDY OBJECTIVE: Glucocorticoids as a component of multimodal analgesia have been studied for many years and their post-operative analgesic effects appear to be dose-dependent. We conducted a systematic review of randomized controlled trials (RCTs) to evaluate the evidence of peri-operative high dose corticosteroid therapy in comparison to placebo (placebo drug) or control group (no treatment) for improving the quality of post-operative analgesia as indicated by a reduction of 10 mm in 100 mm Visual Analogue Scale (VAS) or reduction of 1 point in a 0-10 point VAS scale, or a reduction of 1 point in an 11-point Numerical Rating Scale (NRS) score, or reduction of rescue opioid analgesia, in patients undergoing all types of surgery. DESIGN: Systematic review of RCTs with meta-analysis. SETTING: Acute postoperative pain treatment in non-obese adult population. INTERVENTIONS: Perioperative administration of high dose of Dexamethasone (≥ 0,2 mg/Kg or ≥ 15 mg), or a corresponding dose of a systemic glucocorticoid. MEASUREMENTS: Primary outcomes were postoperative pain measured in 0-100 mm VAS score at 24 h after surgery upon rest and movement. Secondary outcomes were postoperative pain 0-100 mm VAS score 48 h after surgery, postoperative rescue analgesic requirement, postoperative nausea and vomiting (PONV), relevant adverse events. MAIN RESULTS: 47 RCT's were included (3943 patients). The Mean Difference (MD) of 100 mm VAS scores for pain at rest 24 h after surgery was -6.18 mm 95% CI [-8.53, -3.83], at motion -8.86 mm 95% CI [-11.82, -5.89]. Opioid analgesic requirements evaluated in Oral Morphine Equivalents (OME) was -10.00 mg 95% CI [-13.65, -6.34]. PONV events Odds Ratio of 0.29 95%CI [0.24, 0.36]. Major adverse events OR was 0.88 95% CI [0.65, 1.19]. Minor adverse events OR 1.29 95% CI [0.86, 1.92]. CONCLUSION: High doses of glucocorticoids are one of the many possible tools available in multimodal postoperative analgesia, possibly reducing opioids consumption and recurrence of PONV but with no relevant effects in terms of reduction of postoperative VAS score. Available data show a safe therapeutic profile, without increase adverse events. PROTOCOL REGISTRATION: CRD42020137119.

Regional anaesthesia (RA) has an important and ever-expanding role in ambulatory surgery. Specific practices vary depending on the preferences and resources of the anaesthesia team and hospital setting. It is used for various purposes, including as primary anaesthetic technique for surgery but also as postoperative analgesic modality. The limited duration of action of currently available local anaesthetics limits their application in postoperative pain control and enhanced recovery. The search for the holy grail of regional anaesthetics continues. Current evidence suggests that a peripheral nerve block performed with long-acting local anaesthetics in combination with intravenous or perineural dexamethasone gives the longest and most optimal sensory block. In this review, we outline some possible blocks for ambulatory surgery and additives to perform RA. Moreover, we give an update on local anaesthesia drugs and adjuvants, paediatric RA in ambulatory care and discuss the impact of RA by COVID-19.

Remimazolam is anticipated to be an interesting anaesthetic and sedative. It combines the pharmacodynamic properties of midazolam with pharmacokinetic properties similar to remifentanil. However, worrisome case reports of anaphylaxis, delayed emergence and re-sedation have emerged recently and necessitate further investigation.PubMed (including MEDLINE) and EMBASE were searched for all studies reporting serious adverse events where remimazolam was administered for sedation or anaesthesia.Thirty-six case reports and 73 trials were identified, involving a total of 6740 patients who received remimazolam. Hypotension was reported in 911 cases, delayed emergence in 68 cases, anaphylaxis in 10 cases and re-sedation in 8 cases. The incidence of hypotension seems to be lower compared with other anaesthetics, even in high-risk patients.Delayed emergence might be related to the metabolism of remimazolam through carboxylesterase 1 (CES1), a tissue esterase predominant in the liver. There is significant interindividual variation, and it is inhibited by flavonoids, fatty acids and alcohol. Individual benzodiazepine sensitivity has also been reported. A higher BMI, older age and low plasma albumin concentration are risk factors for delayed emergence. Anaphylaxis might be related to a non-IgE-mediated effect of the excipient dextran-40 or a partially IgE-mediated reaction to remimazolam itself. Resedation has been reported after flumazenil reversal and is explained by the specific pharmacokinetic properties of flumazenil and remimazolam. Reversal by flumazenil should be reserved for and used carefully in patients with delayed emergence. VISUAL ABSTRACT: http://links.lww.com/EJA/A864 .
RESUMEN
BACKGROUND: Pain after cardiac surgery via median sternotomy can be difficult to treat, and if inadequately managed can lead to respiratory complications, prolonged hospital stays and chronic pain. OBJECTIVES: To evaluate available literature and develop recommendations for optimal pain management after cardiac surgery via median sternotomy. DESIGN: A systematic review using PROcedure-SPECific Pain Management (PROSPECT) methodology. ELIGIBILITY CRITERIA: Randomised controlled trials and systematic reviews published in the English language until November 2020 assessing postoperative pain after cardiac surgery via median sternotomy using analgesic, anaesthetic or surgical interventions. DATA SOURCES: PubMed, Embase and Cochrane Databases. RESULTS: Of 319 eligible studies, 209 randomised controlled trials and three systematic reviews were included in the final analysis. Pre-operative, intra-operative and postoperative interventions that reduced postoperative pain included paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), intravenous magnesium, intravenous dexmedetomidine and parasternal block/infiltration. CONCLUSIONS: The analgesic regimen for cardiac surgery via sternotomy should include paracetamol and NSAIDs, unless contraindicated, administered intra-operatively and continued postoperatively. Intra-operative magnesium and dexmedetomidine infusions may be considered as adjuncts particularly when basic analgesics are not administered. It is not clear if combining dexmedetomidine and magnesium would provide superior pain relief compared with either drug alone. Parasternal block/surgical site infiltration is also recommended. However, no basic analgesics were used in the studies assessing these interventions. Opioids should be reserved for rescue analgesia. Other interventions, including cyclo-oxygenase-2 specific inhibitors, are not recommended because there was insufficient, inconsistent or no evidence to support their use and/or due to safety concerns.

BACKGROUND: Pain after craniotomy can be intense and its management is often suboptimal. OBJECTIVES: We aimed to evaluate the available literature and develop recommendations for optimal pain management after craniotomy. DESIGN: A systematic review using procedure-specific postoperative pain management (PROSPECT) methodology was undertaken. DATA SOURCES: Randomised controlled trials and systematic reviews published in English from 1 January 2010 to 30 June 2021 assessing pain after craniotomy using analgesic, anaesthetic or surgical interventions were identified from MEDLINE, Embase and Cochrane Databases. ELIGIBILITY CRITERIA: Each randomised controlled trial (RCT) and systematic review was critically evaluated and included only if met the PROSPECT requirements. Included studies were evaluated for clinically relevant differences in pain scores, use of nonopioid analgesics, such as paracetamol and NSAIDs, and current clinical relevance. RESULTS: Out of 126 eligible studies identified, 53 RCTs and seven systematic review or meta-analyses met the inclusion criteria. Pre-operative and intra-operative interventions that improved postoperative pain were paracetamol, NSAIDs, intravenous dexmedetomidine infusion, regional analgesia techniques, including incision-site infiltration, scalp nerve block and acupuncture. Limited evidence was found for flupirtine, intra-operative magnesium sulphate infusion, intra-operative lidocaine infusion, infiltration adjuvants (hyaluronidase, dexamethasone and α-adrenergic agonist added to local anaesthetic solution). No evidence was found for metamizole, postoperative subcutaneous sumatriptan, pre-operative oral vitamin D, bilateral maxillary block or superficial cervical plexus block. CONCLUSIONS: The analgesic regimen for craniotomy should include paracetamol, NSAIDs, intravenous dexmedetomidine infusion and a regional analgesic technique (either incision-site infiltration or scalp nerve block), with opioids as rescue analgesics. Further RCTs are required to confirm the influence of the recommended analgesic regimen on postoperative pain relief.

Preclinical research concerning anaesthesia-induced neurotoxicity was initiated in 1999. A decade later, the earliest clinical observational data showed mixed results in neurodevelopmental outcomes following anaesthesia exposure at a young age. Hence to date, preclinical studies remain the cornerstone of research in this field, primarily because of the vulnerability of clinical observational studies to confounding bias. This review summarises current preclinical evidence. Most studies used rodent models, although non-human primates have also been employed. Across all gestational and postnatal ages, there is evidence that all commonly used general anaesthetics induce neuronal injury (e.g. apoptosis) and cause neurobehavioural impairment (e.g. learning and memory deficits). These deficits were more pronounced when animals were subjected to either repeated exposure, prolonged durations of exposure or higher doses of anaesthesia. To interpret these results in the clinical context, the strengths and limitations of each model and experiment should be carefully considered, as these preclinical studies were often biased by supraclinical durations and a lack of control with regard to physiological homeostasis.

Brain development is initiated at around 3 weeks of gestation. The peak velocity of brain weight gain occurs around birth, with the neural circuitry subsequently being refined until at least 20 years of age. Antenatal and postnatal general anaesthesia suppresses neuronal firing during this critical period and may therefore impair brain development, referred to as "anaesthesia-induced neurotoxicity". Whilst up to 1% of children are exposed to general anaesthesia antenatally (e.g., as an innocent bystander to maternal laparoscopic appendectomy), 15% of children under 3 years of age undergo general anaesthesia postnatally (e.g., otorhinolaryngologic surgery). In this article, the history of preclinical and clinical research in anaesthesia-induced neurotoxicity will be reviewed, starting from the pioneering preclinical study in 1999 until the most recent systematic reviews. The mechanisms of anaesthesia-induced neurotoxicity are introduced. Finally, an overview of the methods used in preclinical studies will be provided, with a comparison of the different animal models that have been employed to investigate this phenomenon.

This article provides a comprehensive review of the technique, drugs of choice, and potential side effects and complications associated with the drugs used and the single-shot spinal anaesthesia (SSS) technique for caesarean delivery. Although neuraxial analgesia and anaesthesia are generally considered safe, all interventions come with potential adverse effects. As such, the practice of obstetric anaesthesia has evolved to minimize such risks. This review highlights the safety and efficacy of SSS for caesarean delivery while also discussing potential complications such as hypotension, postdural puncture headache, and nerve injury. In addition, drug selection and dosages are examined as well, emphasizing the importance of individualized treatment plans and close monitoring for optimal outcomes.
