Training and assessment of skills in neuraxial access-Protocol of a scoping review.

BACKGROUND: Access to the neuraxial space, including lumbar punctures and neuraxial anaesthesia, is an everyday procedure in clinical practice. Traditionally these procedures rely on manual palpation technique, but ultrasound is a useful tool when patients prove challenging. Presently, there is a lack of evidence-based guidelines for technical skills acquisition, both with and without ultrasound, and likewise, competency assessment approaches vary globally. Accordingly, we aim to assess the current evidence regarding learning and assessment in neuraxial access ± $$ \pm $$ ultrasound, for future educational recommendations. METHODS: This scoping review will be conducted in accordance with the Preferred Reporting Items for Systematic and Meta-Analysis (PRISMA) statement, together with the PRISMA Extension for Scoping Reviews. A systematic search strategy will be based on a PICO approach, focusing on physicians, medical students, or nurses being exposed to education, training, or assessment in procedural neuraxial access ± $$ \pm $$ ultrasound. No comparators are obligated, but outcomes should be assessable using the Kirkpatrick four levels of training evaluation. The search will be performed in Cochrane Library, Embase, Medline, Scopus, PubMed, and CINAHL. Independently, two authors will screen the studies and conflicts will be resolved by a third author. Relevant predefined data will be extracted and analysed using a descriptive approach. The quality of the studies will be assessed using the Medical Education Research Study Quality Instrument. DISCUSSION: This scoping review will contribute by presenting gathered evidence of an overview of the different approaches to achieving education and training of technical skills in neuraxial access, and how skills are tested, which could guide research and future recommendations for skills development and assessment.

Determining the Maximum Tolerable Concentration of Ropivacaine to Maintain Sensation of the Nerve Root in Percutaneous Endoscopic Transforaminal Lumbar Discectomy: Can Epidural Anaesthesia Achieve Pain-Tactile Separation Block to Avoid Nerve Injury?

Introduction: Nerve injury is a serious complication of percutaneous endoscopic transforaminal lumbar discectomy due to nerve root contact. The maximum tolerable concentration (MTC) of ropivacaine concentration for epidural anaesthesia, is defined as the concentration that minimises pain while preserving the sensation of the nerve roots. This distinct advantage allows the patient to provide feedback to the surgeon when the nerve roots are contacted. Methods: We used a biased-coin design to determine the MTC, which was estimated by the 10% effective concentration (EC10), ie, the concentration at which 10% of patients lost sensation in the nerve roots. The determinant for positive response was lack of sensory feedback upon contact with the nerve root, and the feedback from occurrence of sensations in the innervation area upon contact with the nerve root was defined as a negative response. Primary outcome was the response from contact nerve root. Secondary outcomes were the type and number of statements of negative response and each patient's pain score during surgery. Results: Fifty-four patients were included in this study. The EC10 was 0.434% (95% CI: 0.410%, 0.440%) using isotonic regression in comparison with 0.431% (95% CI: 0.399%, 0.444%) using probit regression. Three type statements of negative response were reported including "tactile sensation", radiculalgia, and numbness. Conclusion: The MTC of ropivacaine used for epidural anaesthesia was 0.434% to avoid nerve injury in percutaneous endoscopic transforaminal lumbar discectomy.

Programmed intermittent epidural bolus regimen vs continuous epidural infusion: a retrospective study of motor block and obstetric outcomes using the Robson's Ten Group Classification System.

BACKGROUND: Use of a programmed intermittent epidural bolus (PIEB) regimen during labour is associated with several benefits over a continuous epidural infusion (CEI), including reduced local anaesthetic consumption and reduced risk of motor block. We hypothesise that the benefits of a PIEB regimen may vary according to the Robson Ten Group Classification System (TGCS). The aim of this study was to determine if introduction of a PIEB regimen was associated with reduced incidence of motor block. We also wished to examine changes in obstetric outcomes following PIEB introduction across the Robson TGCS. METHODS: This was a single-centre retrospective cohort study. Data were collected over two three-month periods before and after PIEB introduction. The primary outcome was the incidence of motor block. Maternal and obstetric outcomes across Robson Groups 1-4 were analysed. RESULTS: Introduction of PIEB was associated with reduced incidence of motor block (28.4% (95% CI 25.7% to 31.3%) vs 22.4%, (95% CI 19.9% to 25.2%), difference 5.9% (95% CI 1.0% to 21.1%), P=0.003), with no association with changes in rates of caesarean section, operative vaginal delivery or other obstetric outcomes. Use of a PIEB regimen was associated with reduced incidence of motor block in Robson Group 4a (20.3% (16.0%, 28.0%) vs 12.0%, (7.6%, 16.4%), difference 9.9% (95% CI -17.4% to -2.4%) P=0.009). There were no significant changes in other outcomes assessed across Robson TGCS. CONCLUSION: Introduction of PIEB for maintenance of labour analgesia was associated with reduced incidence of motor block in our institution compared with CEI. Presenting results according to Robson's TGCS in future studies may allow better elucidation of the impact of neuraxial analgesia on maternal and obstetric outcomes.

Post-caesarean Section Headache: A Case Report of Post-dural Puncture Headache and Cerebral Venous Thrombosis Following Epidural Anaesthesia.

Post-dural puncture headache (PDPH) is a common complication of epidural and spinal anaesthesia in obstetric medicine. In rare cases, PDPH can be associated with complications such as cerebral venous thrombosis (CVT) as well. We discuss a recent case of a young female who developed PDPH and CVT concurrently after undergoing epidural anaesthesia for initially uncomplicated labour and delivered via an emergency caesarean section. She developed an orthostatic headache a few hours post administration of the epidural anaesthetic, which was initially treated as a suspected PDPH by giving simple analgesia and caffeine. Her symptoms did not improve and she underwent further neuroimaging, which revealed the development of a CVT. Despite the prompt administration of enoxaparin, the headache persisted and did not respond to increased doses of analgesia. After deliberation and inter-departmental discussion, an epidural blood patch was performed, leading to the prompt resolution of the headache. This report highlights a rare concurrence of PDPH and CVT, causing a diagnostic dilemma that resulted in treatment delays for the patient. Treating both conditions raises difficult practical questions, especially regarding the use of an epidural blood patch as opposed to anticoagulation. Given the risk of fatal complications such as venous cerebral infarction, seizures, and subdural hematoma, prompt treatment of both PDPH and CVT is strongly recommended. The multifactorial mechanism by which CVT develops with intracranial hypotension and PDPH also makes it essential for clinicians to keep an open mind when managing post-caesarean headaches, requiring inter-departmental cooperation to ensure optimal patient outcomes.

Impact of spinal or epidural anaesthesia on perioperative outcomes in adult noncardiac surgery: a narrative review of recent evidence.

Spinal and epidural anaesthesia and analgesia are important anaesthetic techniques, familiar to all anaesthetists and applied to patients undergoing a range of surgical procedures. Although the immediate effects of a well-conducted neuraxial technique on nociceptive and sympathetic pathways are readily observable in clinical practice, the impact of such techniques on patient-centred perioperative outcomes remains an area of uncertainty and active research. The aim of this review is to present a narrative synthesis of contemporary clinical science on this topic from the most recent 5-year period and summarise the foundational scholarship upon which this research was based. We searched electronic databases for primary research, secondary research, opinion pieces, and guidelines reporting the relationship between neuraxial procedures and standardised perioperative outcomes over the period 2018-2023. Returned citation lists were examined seeking additional studies to contextualise our narrative synthesis of results. Articles were retrieved encompassing the following outcome domains: patient comfort, renal, sepsis and infection, postoperative cancer, cardiovascular, and pulmonary and mortality outcomes. Convincing evidence of the beneficial effect of epidural analgesia on patient comfort after major open thoracoabdominal surgery outcomes was identified. Recent evidence of benefit in the prevention of pulmonary complications and mortality was identified. Despite mechanistic plausibility and supportive observational evidence, there is less certain experimental evidence to support a role for neuraxial techniques impacting on other outcome domains. Evidence of positive impact of neuraxial techniques is best established for the domains of patient comfort, pulmonary complications, and mortality, particularly in the setting of major open thoracoabdominal surgery. Recent evidence does not strongly support a significant impact of neuraxial techniques on cancer, renal, infection, or cardiovascular outcomes after noncardiac surgery in most patient groups.

Anestesia neuroaxial en pacientes portadores de dispositivos de derivación de líquido cefalorraquídeo: revisión descriptiva / Neuraxial anaesthesia in patients with cerebrospinal fluid shunts: A descriptive review

La anestesia neuroaxial en pacientes portadores de dispositivos de derivación de líquido cefalorraquídeo (LCR) se ha asociado clásicamente a un alto riesgo de complicaciones. Con el fin de recabar toda la evidencia disponible, se realizó una búsqueda estructurada de los trabajos publicados en usuarios portadores de estos dispositivos, sometidos a algún tipo de técnica neuroaxial para procedimientos obstétricos o quirúrgicos no relacionados con el mismo, valorando la eficacia de la técnica y las complicaciones perioperatorias. Solo se encontraron series de casos y casos clínicos (n = 72). Se identificó uno de insuficiente cobertura anestésica, que precisó una modificación de la técnica, así como una complicación intraoperatoria con compromiso de seguridad para el sujeto. No se describió ningún caso de infección ni disfunciones posoperatorias del dispositivo relacionadas con el método anestésico. La evidencia hallada es escasa y de baja calidad, lo que no permite establecer conclusiones significativas, aunque los pacientes podrían beneficiarse de una valoración individualizada. (AU)

Neuraxial anesthesia in patients with cerebrospinal fluid (CSF) shunt devices has traditionally been associated with a high risk of complications. In order to gather all available evidence, a structured search was conducted to include published studies involving users of these devices, undergoing any form of neuraxial technique for obstetric or surgical procedures unrelated to them. Effectiveness of the technique and perioperative complications were assessed. Only case series and case reports (n = 72) were identified. One patient was found to have insufficient anesthetic coverage, necessitating a modification of the technique, and another one had an intraoperative complication which compromised the subject's safety. No infection events or postoperative device dysfunction related to the anesthetic method were described. The evidence found is scarce and of low quality, preventing the establishment of significant conclusions. Nevertheless, patients may obtain benefit from an individualized evaluation. (AU)

Continuous stellate ganglion block for ventricular arrhythmias: case series, systematic review, and differences from thoracic epidural anaesthesia.

AIMS: Percutaneous stellate ganglion block (PSGB) through single-bolus injection and thoracic epidural anaesthesia (TEA) have been proposed for the acute management of refractory ventricular arrhythmias (VAs). However, data on continuous PSGB (C-PSGB) are scant. The aim of this study is to report our dual-centre experience with C-PSGB and to perform a systematic review on C-PSGB and TEA. METHODS AND RESULTS: Consecutive patients receiving C-PSGB at two centres were enrolled. The systematic literature review follows the latest Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Our case series (26 patients, 88% male, 60 ± 16 years, all with advanced structural heart disease, left ventricular ejection fraction 23 ± 11%, 32 C-PSGBs performed, with a median duration of 3 days) shows that C-PSGB is feasible and safe and leads to complete VAs suppression in 59% and to overall clinical benefit in 94% of cases. Overall, 61 patients received 68 C-PSGBs and 22 TEA, with complete VA suppression in 63% of C-PSGBs (61% of patients). Most TEA procedures (55%) were performed on intubated patients, as opposed to 28% of C-PSGBs (P = 0.02); 63% of cases were on full anticoagulation at C-PSGB, none at TEA (P < 0.001). Ropivacaine and lidocaine were the most used drugs for C-PSGB, and the available data support a starting dose of 12 and 100 mg/h, respectively. No major complications occurred, yet TEA discontinuation rate due to side effects was higher than C-PSGB (18 vs. 1%, P = 0.01). CONCLUSION: Continuous PSGB seems feasible, safe, and effective for the acute management of refractory VAs. The antiarrhythmic effect may be accomplished with less concerns for concomitant anticoagulation compared with TEA and with a lower side-effect related discontinuation rate.

Ultrasound-guided caudal anaesthesia combined with epidural anaesthesia for caesarean section: a randomized controlled clinical trial.

BACKGROUND: Although epidural anaesthesia and spinal anaesthesia are currently the general choices for patients undergoing caesarean section, these two neuraxial anaesthesia methods still have drawbacks. Caudal anaesthesia has been considered to be more appropriate for gynaecological surgery. The purpose of this study was to compare epidural anaesthesia combined with caudal anaesthesia, spinal anaesthesia and single-space epidural anaesthesia for caesarean section with respect to postoperative comfort and intraoperative anaesthesia quality. METHODS: In this clinical trial, 150 patients undergoing elective caesarean section were recruited and randomized into three groups according to a ratio of 1:1:1to receive epidural anaesthesia only, spinal anaesthesia only or epidural anaesthesia combined with caudal anaesthesia. The primary outcome was postoperative comfort in the three groups. Secondary outcomes included intraoperative anaesthesia quality and the incidences of nausea, vomiting, postdural puncture headache, maternal bradycardia, or hypotension. RESULTS: More patients were satisfied with the intraoperative anaesthesia quality in the EAC group than in the EA group (P = 0.001). The obstetrician was more significantly satisfied with the intraoperative anaesthesia quality in the SA and EAC groups than in the EA group (P = 0.004 and 0.020, respectively). The parturients felt more comfortable after surgery in the EA and EAC groups (P = 0.007). The incidence of maternal hypotension during caesarean section was higher in the SA group than in the EA and EAC groups (P = 0.001 and 0.019, respectively). CONCLUSIONS: Epidural anaesthesia combined with caudal anaesthesia may be a better choice for elective caesarean section. Compared with epidural anaesthesia and spinal anaesthesia, it has a higher quality of postoperative comfort and intraoperative anaesthesia.

Treatment and Prevention of Post-dural Puncture Headaches: A Systematic Review.

Post-dural puncture headache (PDPH) is occasionally an inevitable side effect of neuraxial anesthesia, which can happen after spinal anesthesia or if an accidental dural puncture (ADP) happens during epidural anesthesia. The treatment and prevention options for PDPH differ widely from one institution to another. The management of PDPH is heterogeneous in many institutions because of the absence of clear guidelines and protocols for the management of PDPH. This study aimed to summarize all articles published during the past decade that discussed the treatment or prevention of PDPH. From 2013 to 2023, 345 publications were filtered for all treatment and prevention approaches used for PDPH patients. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020 guidelines were followed for conducting this systematic review, and 38 articles were included for analysis and review. Existing data come from small randomized clinical trials and retrospective or prospective cohort studies. This review supports the effect of oral pregabalin and intravenous aminophylline in both treatment and prevention. Intravenous mannitol, intravenous hydrocortisone, triple prophylactic regimen, and neostigmine plus atropine combination showed effective and beneficial outcomes. On the other hand, neither neuraxial morphine nor epidural dexamethasone showed promising results. Consequently, the use of neuraxial morphine or epidural dexamethasone for the prevention of PDPH remains questionable. Regarding the posture of the patient and its consequences on the incidence of the headache, lateral decubitus is better than a sitting position, and a prone position is better than a supine position. Smaller non-cutting needles play a role in avoiding PDPH. Minimally invasive nerve blocks, including sphenopalatine ganglion or greater occipital nerves, are satisfyingly effective. Epidural blood patches remain the more invasive but the gold standard and ultimate solution in patients resisting medical therapy. This study highlights the need for larger research to define the best approach to prevent and treat PDPH.

Neuraxial anaesthesia in patients with cerebrospinal fluid shunts: A descriptive review.

Neuraxial anesthesia in patients with cerebrospinal fluid (CSF) shunt devices has traditionally been associated with a high risk of complications. In order to gather all available evidence, a structured search was conducted to include published studies involving users of these devices, undergoing any form of neuraxial technique for obstetric or surgical procedures unrelated to them. Effectiveness of the technique and perioperative complications were assessed. Only case series and case reports (n = 72) were identified. One patient was found to have insufficient anesthetic coverage, necessitating a modification of the technique, and another one had an intraoperative complication which compromised the subject's safety. No infection events or postoperative device dysfunction related to the anesthetic method were described. The evidence found is scarce and of low quality, preventing the establishment of significant conclusions. Nevertheless, patients may obtain benefit from an individualized evaluation.

Effect of esketamine on postpartum depression after labor analgesia and potential mechanisms: a randomized, double-blinded controlled trial.

BACKGROUND: To evaluate the effect of esketamine combined with ropivacaine hydrochloride on the occurrence of postpartum depression (PPD) after labor analgesia under epidural analgesia pump and explore the possible mechanisms. METHODS: A total of 120 women aged 24 to 36 years old who underwent labor analgesia by epidural analgesia pump, with American Society of Anesthesiologists (ASA) physical status II were enrolled. According to the formula of epidural analgesia pump, all participants were randomly divided into two groups: esketamine group (Group E) and control group (Group C). Epidural anaesthesia were operated in all women between L2 and L3 after cervical dilation up to 2 ~ 3 cm. After successful puncture, the epidural catheter was placed 3.5 cm toward the head and 1% lidocaine was injected for 3 ml. The epidural analgesia pump was connected. Esketamine (0.2 mg/kg) combined with 0.75% ropivacaine hydrochloride (20 ml) were diluted by normal saline up to 100 ml in Group E, when only the equal dose of ropivacaine hydrochloride was used in Group C. The visual analogue scale (VAS) before analgesia (T1), 5 (T2), 10 (T3) and 20 (T4) minutes after analgesia were measured. The duration of the first and second stage of labor, the Apgar score of fetus at delivery, postpartum hemorrhage, consumption of esketamine and ropivacaine were recorded. The incidence of PPD was recorded at 1 week and 6 weeks after delivering. The occurrence of side effects such as nausea and vomiting, dizziness, and nightmares were also recorded for 48 h after delivering. The levels of leptin, norepinephrine(NE), and epinephrine(E) in the peripheral venous blood were measured before labor analgesia and at 24 h, 1 week, and 6 weeks after delivering. RESULTS: Compared with Group C, the VAS score at T2, T3 and T4 were significantly lower in Group E (P < 0.01). Compared with Group C, the incidence of PPD was significantly lower at 1 week and 6 weeks after delivering in Group E (P < 0.01). Compared with Group C, the levels of leptin were significantly higher at 24 h and 1 week after delivering in Group E (P < 0.01), while NE and E (P < 0.01) were lower at the same time (P < 0.01). There were no significant difference of the duration of the first and second stage of labor, the Apgar score of fetus at delivery, postpartum hemorrhage, consumption of ropivacaine and the side effects for 48 h after delivering between the two groups. CONCLUSION: Esketamine combined with ropivacaine hydrochloride used in labor analgesia can significantly reduce the incidence of postpartum depression after delivering without increasing related side effects, which may be related to the regulation of leptin, norepinephrine, and epinephrine in the serum. TRIAL REGISTRATION: The trial was registered at the Chinese Clinical Trial Registry on 30/05/2022 (CTRI registration number-ChiCTR2200060387). URL of registry: https://www.chictr.org.cn/bin/home .

Combined spinal and epidural anaesthesia for open radical cystectomy: A controlled study.

Objectives: To evaluate the feasibility of loco-regional anaesthesia and to compare perioperative outcomes between loco-regional and standard general anaesthesia in patients with bladder cancer undergoing open radical cystectomy (ORC). Patients and Methods: A single-surgeon cohort of 60 consecutive patients with bladder cancer undergoing ORC with an enhanced recovery after surgery protocol between May 2020 and December 2021 was analysed. A study group of 15 patients operated on under combined spinal and epidural anaesthesia was compared with a control group of 45 patients receiving standard general anaesthesia. Intraoperative outcomes were haemodynamic stability, estimated blood loss, intraoperative red blood cell transfusion rate, and anaesthesia time. Postoperative outcomes were pain assessment 24 h after surgery, time to mobilisation, return to oral diet, time to bowel function recovery, length of stay and rate of 90-day complications. Results: No patients required conversion from loco-regional to general anaesthesia. All patients in both groups were haemodynamically stable. No significant differences between groups were observed for all other intraoperative outcomes, except for a shorter anaesthesia time in the study versus control group (250 vs. 290 min, p = 0.01). Pain visual score 24 h after surgery was significantly lower in the study versus control group (0 vs. 2, p < 0.001). No significant differences were observed for all other postoperative outcomes, with a comparable time to bowel function recovery (5 days in each group for stool passage), and 90-day complication rate (46.6% vs. 42.2% for the study vs. control group, p = 0.76). Conclusion: Our exploratory, controlled study confirmed the feasibility, safety and effectiveness of a pure loco-regional anaesthesia in patients with bladder cancer undergoing ORC. No significant differences were observed in intra- and postoperative outcomes between loco-regional and general anaesthesia, except for a significantly shorter anaesthesia time and greater pain reduction in the early postoperative period for the former.

Two-stage laparoscopic transversus abdominis plane block as an equivalent alternative to thoracic epidural anaesthesia in bowel resection-an explorative cohort study.

PURPOSE: We evaluated the effect of the two-stage laparoscopic transversus abdominis plane block (TS-L-TAPB) in comparison to thoracic epidural anaesthesia (TEA) and a one-stage L-TAPB (OS-L-TAPB) in patients who underwent elective laparoscopic bowel resection. METHODS: We compared a TS-L-TAPB (266 mg bupivacaine), which was performed bilaterally at the beginning and end of surgery, with two retrospective cohorts. These were patients who had undergone a TEA (ropivacaine/sufentanil) or an OS-L-TAPB (200 mg ropivacaine) at the beginning of surgery. Oral and i.v. opiate requirements were documented over the first 3 postoperative days (POD). RESULTS: Patients were divided into three groups TEA (n = 23), OS-L-TAPB (n = 75), and TS-L-TAPB (n = 49). By the evening of the third POD, patients with a TEA had a higher cumulative opiate requirement with a median of 45.625 mg [0; 202.5] than patients in the OS-L-TAPB group at 10 mg [0; 245.625] and the TS-L-TAPB group at 5.625 mg [0; 215.625] (p = 0.1438). One hour after arrival in the recovery room, significantly more patients in the TEA group (100%) did not need oral and i.v. opioids than in the TS-L-TAPB (78%) and OS-L-TAPB groups (68%) (p = 0.0067).This was without clinical relevance however as the median in all groups was 0 mg. On the third POD, patients in the TEA group had a significantly higher median oral and i.v. opioid dose at 40 mg [0; 80] than the TS-L-TAPB and OS-L-TAPB groups, both at 0 mg [0; 80] (p = 0.0009). CONCLUSION: The TS-L-TAP showed statistically significant and clinically meaningful benefits over TEA and OS-L-TAP in reducing postoperative opiate requirements.

Comparative efficacy of ultrasound guidance or conventional anatomical landmarks for neuraxial puncture in adult patients: a systematic review and network meta-analysis.

BACKGROUND: Preprocedural, real-time, and computer-aided three-dimensional ultrasound has been widely used for neuraxial puncture; however, the optimal guidance is unclear. We examined the comparative efficacy of three ultrasound guidance and anatomical landmarks for neuraxial puncture in adults. METHODS: We searched for randomised controlled studies comparing the efficacy of ultrasound guidance and anatomical landmarks for neuraxial puncture in adults using electronic databases and unpublished studies. The primary outcomes were first-pass success and patient satisfaction. A random-effects network meta-analysis (NMA) was used. RESULTS: We identified 74 eligible studies (7090 patients). Preprocedural ultrasound and real-time ultrasound-guided neuraxial puncture improved first-pass success compared with anatomical landmarks (risk ratio [RR] 1.6; 95% credible interval [CrI] 1.3-1.9; RR 1.9; 95% CrI 1.3-2.9, respectively, moderate confidence). Computer-aided ultrasound-guided neuraxial puncture also increased first-pass success (RR 1.8; 95% CrI 0.97-3.3, low confidence), although estimates were imprecise. However, real-time ultrasound-guided neuraxial puncture resulted in minimal difference in first-pass success compared with preprocedural ultrasound (RR 1.2; 95% CrI 0.8-1.8, moderate confidence). Preprocedural ultrasound improved patient satisfaction slightly compared with anatomical landmark use (standardised mean differences 0.28; 95% CrI 0.092-0.47, low confidence). CONCLUSIONS: This NMA provides evidence supporting ultrasound-guided neuraxial puncture compared with use of anatomical landmarks, including indirect comparisons. Among the three ultrasound guidance methods, preprocedural ultrasound appears to be a better adjunctive option.

The impact of sufentanil versus remifentanil on surgical site wound healing in caesarean section primiparas undergoing epidural anaesthesia: A systematic meta-analysis.

Caesarean section (C-section) is a prevalent obstetric surgical procedure, with the choice of analgesic agents playing a pivotal role in postoperative recovery. This systematic meta-analysis aimed to compare the effects of sufentanil (ST) and remifentanil (RT) on postoperative wound healing in caesarean section primiparas undergoing epidural anaesthesia. A comprehensive search was conducted across multiple databases, adhering to PRISMA guidelines, yielding eight randomized controlled trials (RCTs) for inclusion. The primary outcome was wound healing assessment using the REEDA (redness, edema, ecchymosis, discharge, approximation) scale on the third, fifth and tenth postoperative days. The meta-analysis encompassed 691 primiparas. A significant difference in wound healing was observed between ST and RT on the third (I2 = 99%; Random: SMD: 6.75, 95% CIs: 3.11-10.39, p < 0.01) and fifth days (I2 = 99%; Random: SMD: 3.63, 95% CIs: 1.56-5.70, p < 0.01) postcaesarean section. However, no significant difference was noted on the tenth day (I2 = 5%; Random: SMD: 0.00, 95% CIs: -0.45-0.45, p = 0.35). Sufentanil and remifentanil exhibit differential effects on early postoperative wound healing in caesarean section primiparas undergoing epidural anaesthesia. While both opioids are effective analgesics, sufentanil demonstrates a more pronounced impact on wound healing during the immediate postoperative days. Clinicians should consider these findings when selecting an opioid for pain management in this patient population.

Locoregional Anaesthesia for Laparotomy: A Literature Review and Subsequent Case Series Highlighting the Potential of an Alternative Anaesthetic Technique.

Laparotomy is a surgical incision utilised in both emergency and elective scenarios to gain access to abdominal surgery. General anaesthesia is usually necessitated due to the substantial insult of the approach and to facilitate organ relaxation and paralysis. However, this brings with it the need for an assessment of the suitability of the anaesthetic technique, with a large number of patients having comorbidities significant enough to exclude them from surgery. Locoregional anaesthesia, provided via spinal, epidural, or a combined approach offers a means of providing anaesthesia that places a reduced level of strain on patients' cardiorespiratory function. We review the existing literature on the topic of so-called "awake laparotomy" performed with locoregional anaesthesia and present a case series including both elective and emergency procedures.

Anesthetic Management of an Obstetric Patient With Ehlers-Danlos and Wolff-Parkinson-White Syndromes.

A 31-year-old, primigravida, nullipara (G1P0) female with a past medical history of Ehlers-Danlos Syndrome (EDS), newly diagnosed Wolff-Parkinson-White Syndrome (WPW), and fetal breech presentation initially presented at 36+5 weeks gestation for an external cephalic version (ECV). The patient noted significant symptomatology related to her WPW which had worsened over the course of her pregnancy despite being started on oral metoprolol. Despite joint recommendations from the anesthesia and obstetric teams to combine the ECV with a same-day scheduled induction of labor or cesarean section, the patient declined. An epidural catheter was placed using ultrasound guidance and slowly titrated with 2% lidocaine; however, the ECV was unsuccessful. At 39 weeks gestation, the patient underwent an uncomplicated low transverse cesarean section under combined spinal-epidural anesthesia. The patient was discharged two days later in stable condition with a referral to an electrophysiologist. Here we describe the anesthetic preparation and management for an external cephalic version and subsequent cesarean section in a patient with these two rare conditions.

Postpartum complications following neuraxial anaesthesia for obstetric physicians.

Neuraxial analgesia and anaesthesia are widely accepted and well-tolerated modes of delivery analgesia, being employed in up to 76% of vaginal deliveries and 94% of caesarean deliveries in the United States.1 A cause of considerable concern for postpartum women, their family and caring health professionals is the occurrence of unexplained postpartum complications, not only for management in the index pregnancy, but the uncertain risk of recurrence in future pregnancies. Complications of neuraxial blocks may impact significantly on the ability of mothers to care for and bond with their newborn. The reported incidence of temporary neurological deficit following obstetric neuraxial blocks is 1 in 3900 procedures, and the risk of permanent neurological harm estimated to be between 1 in 80,000 and 1 in 320,425 procedures.2 Obstetric physicians may be asked to review women with postpartum complications following neuraxial blocks. This article reviews complications that may be seen following neuraxial blocks for delivery.

Serious complications related to regional anaesthesia: Study of Greek Courts' Decisions.

BACKGROUND: Regional anaesthesia and analgesia present many advantages. Related complications are few and have been fully described. Information on regional anaesthesia malpractice is lacking in Greece. The objectives of the analysis were to highlight areas of high litigation risk and report the financial impact of claims. METHODS: Published judicial decisions of criminal, civil, administrative and disciplinary content, from 1995 to 2020, were searched in the legal information banks. The court decisions were analysed by an expert in collaboration with the lawyers of the investigation. RESULTS: A total of 26 court decisions related to complications from regional anaesthesia were found involving 10 cases, which comprised: 8 convictions, 1 referral of the case for a new expert opinion and 1 acquittal. In 6 cases the medical negligence involved complications after epidural anaesthesia and in 2 after subarachnoid anaesthesia. In 1 case there was collective liability of the anaesthesiologist and the obstetrician for negligent homicide and in 7 cases liability of the anaesthesiologist for bodily injuries. The duration of the litigation was 5-16 years. CONCLUSIONS: Analysis of court cases made it possible to identify the causes that led to complications during regional anaesthesia. Informed consent, non-traumatic technique, careful patient selection, adherence to safety rules, and early diagnosis and treatment of complications are essential to avoid permanent injury.
