General anesthesia vs. conscious sedation and local anesthesia for endovascular treatment in patients with posterior circulation acute ischemic stroke: An updated systematic review and meta-analysis.

INTRODUCTION: The best anesthetic choice for patients with acute posterior circulation stroke during endovascular treatment (EVT) remains uncertain. METHOD: We searched five databases to identify studies that met the inclusion criteria. Our primary outcome measure was functional independence (FI). Secondary outcomes were 3-month mortality, any intracranial hemorrhage (ICH), symptomatic ICH (sICH), successful reperfusion, and procedure- and ventilator-associated complications. RESULTS: A total of 10 studies were included in our meta-analysis. No significant differences were detected between the general anesthesia (GA) and conscious sedation and local anesthesia (CS/LA) groups in 3-month FI (nine studies; OR=0.69; 95% CI 0.45-1.06; P=0.083; I2=66%;), 3-month mortality (nine studies; OR=1.41; 95% CI 0.94-2.11; P=0.096; I2=61.2%;), any ICH (three studies; OR=0.75; 95% CI 0.44-1.25; P=0.269; I2=0%;), or sICH (six studies; OR=0.64; 95% CI 0.40-1.04; P=0.073; I2=0%;). No significant differences were observed for successful reperfusion (10 studies; OR=1.17; 95% CI 0.91-1.49; P=0.219; I2=0%;), procedure-related complications (four studies; OR=1.14; 95% CI 0.70-1.87; P=0.603; I2=7.9%;), or respiratory complications (four studies; OR=1.19; 95% CI 0.61-2.32; P=0.616; I2=64.9%;) between the two groups. CONCLUSIONS: Our study showed no differences in 3-month FI, 3-month mortality, and successful reperfusion between patients treated with GA and those treated with CS/LA. Additionally, no increased risk of hemorrhagic transformation or pulmonary infection was observed in the CS/LA group. These results indicate that CS/LA may be an EVT option for acute posterior circulation stroke patients.

Local versus General Anaesthesia for Transcatheter Aortic Valve Implantation (TAVI): A Systematic Review, Meta-Analysis, and Trial Sequential Analysis of Randomised and Propensity-Score Matched Studies.

Transcatheter aortic valve implantation (TAVI) is a common practice for severe aortic stenosis, but the choice between general (GA) and local anesthesia (LA) remains uncertain. We conducted a comprehensive literature review until April 2023, comparing the safety and efficacy of LA versus GA in TAVI procedures. Our findings indicate significant advantages of LA, including lower 30-day mortality rates (RR: 0.69; 95% CI [0.58, 0.82]; p < 0.001), shorter in-hospital stays (mean difference: -0.91 days; 95% CI [-1.63, -0.20]; p = 0.01), reduced bleeding/transfusion incidents (RR: 0.64; 95% CI [0.48, 0.85]; p < 0.01), and fewer respiratory complications (RR: 0.56; 95% CI [0.42, 0.76], p<0.01). Other operative outcomes were comparable. Our findings reinforce prior evidence, presenting a compelling case for LA's safety and efficacy. While patient preferences and clinical nuances must be considered, our study propels the discourse towards a more informed anaesthesia approach for TAVI procedures.

Effect of Language Arousal Nursing Combined with Thermal Insulation Nursing on MAP, SPO2, NRS and Adverse Reactions in Elderly Patients Undergoing Spinal Fracture Surgery Under General Anesthesia.

Objective: To evaluate the effects of language awakening nursing and thermal insulation nursing on anesthesia in elderly patients undergoing spinal fracture surgery. Methods: Randomized control method was used in this study, 200 elderly patients who underwent spinal fracture surgery under general anesthesia between January and December 2022. Among the patients, 100 cases were selected as the observation group, and the other 100 cases were included in the control group by the random number table method. The control group was treated with thermal insulation nursing, and the observation group was given language arousal nursing (a type of care that helps patients regain consciousness after surgery or anesthesia) combined with thermal insulation nursing (A nursing method for maintaining a patient's body temperature in a medical setting). Results: After the intervention, the observation group showed shorter extubation time, awaking time, eye-opening time, and respiratory recovery time compared to the control group (P < .05). Systolic, diastolic, and MAP decreased in both groups after the intervention, with the observation group showing lower values (P < .05). Heart rate at 5 and 10 minutes after extubation decreased in both groups, with the observation group having a lower heart rate than the control group (P < .05). There were no significant differences in SPO2 between the groups after intervention (P > .05). The observation group reported milder pain and a lower incidence of anesthesia-related adverse reactions (P < .05). These findings suggest that language arousal nursing combined with heat preservation nursing improves anesthesia recovery in elderly patients undergoing spinal fracture surgery, leading to better outcomes and reduced adverse events. Conclusion: Combining language arousal and thermal insulation nursing enhances anesthesia recovery in elderly spinal fracture surgery patients, leading to optimized blood pressure, heart rate, reduced pain, and fewer anesthesia-related adverse events.

Effectiveness of acupuncture therapy for the prevention of emergence agitation in children: A systematic review and meta-analysis with trial sequential analysis.

This study aimed to evaluate the effectiveness of acupuncture therapy in preventing emergence agitation (EA) in children. A systematic review and meta-analysis were conducted across multiple locations according to the articles searched. Seven databases, including trial registration sites, were searched. A total of six trials were included involving 489 patients; of them, 244 received acupuncture therapy. Randomized clinical trials (RCTs) evaluating the incidence of EA compared with placebo/sham or standard care in children were included. The primary outcome was the incidence of EA, as evaluated using a specific assessment tool. Data about the incidence rate of EA, heterogeneity, quality of trials and evidence, and adverse events were collected. Additionally, data about patient demographic characteristics, type of anesthesia, duration and onset of acupuncture therapy, EA and pain score, time taken for extubation, and post-anesthesia care unit length of stay were collected. The results indicated that the overall incidence of EA in the acupuncture therapy group and the control group was 23.4% and 39.5%, respectively, with no significant difference (risk ratio, 0.62; 95% confidence interval, 0.26-1.48; I2 = 63%). Subgroup analysis showed a significant difference in the overall incidence of EA in the acupuncture therapy and control groups according to surgery type (high-risk vs. low-risk surgery), suggesting that acupuncture therapy may be effective in reducing EA for patients undergoing high-risk surgery. The quality of evidence was downgraded to "very low" due to the study designs, inconsistency, and possible publication bias. In conclusion, this meta-analysis shows that the currently available RCTs are insufficient to determine the effectiveness of acupuncture therapy in preventing EA in children undergoing general anesthesia.

Does dental rehabilitation under general anaesthetic contribute to the development of temporomandibular disorders in children and adolescents? A scoping review.

BACKGROUND: Temporomandibular disorders (TMDs) have multiple aetiological factors. Although some evidence suggests invasive and lengthy dental procedures may contribute towards TMD development, there is a relative paucity in the literature regarding an association between elements of paediatric dental general anaesthesia (pDGA) and TMDs. This review aims to consider the impact of dental rehabilitation (and its constituent elements) performed under general anaesthesia on the development of TMDs in childhood and adolescence and identify theories and/or gaps in knowledge which may benefit from future research. METHODS: Due to the need to preliminarily examine the nature and extent of the current evidence base, a scoping review approach was chosen. The review was conducted based on the framework provided by the methodological working group of the Joanna Briggs Institute (JBI) for conducting systematic scoping reviews. Electronic databases MEDLINE, Embase, Scopus, Web of Science and Cochrane Library were searched as well as the grey literature using OpenGrey, Nexis, Ethos, Google Scholar and ProQuest, with eligible studies uploaded onto Zotero (Mac Version 5.0.96.2). RESULTS: A total of 810 records were identified. After removing duplicates and those not available in English, 260 were identified for title and abstract screening. Seventy-six records underwent full-text review of which only one met the broad inclusion criteria. The most common reasons for exclusion were no specific relation to general anaesthesia, not specifically relating to dental treatment and only being concerned with TMD management. The included study found that while development of TMDs following dental rehabilitation under GA did occur in children, whether the problems caused by treatment were exacerbated by other elements of the pDGA process remains unknown. CONCLUSION: This review has confirmed a distinct paucity of research in this field. While there is no current tangible scientific evidence that common and routine dental procedures lead to TMD, the literature shows that alterations to any one or a combination of critical factors can contribute to TMD development, which may be collectively exacerbated by iatrogenic macrotrauma during the pDGA process. We have highlighted elements of pre-, peri- and post-operative pDGA, alongside biopsychosocial factors, which may contribute to TMD development in childhood and adolescence and may benefit from future research.

Euthyroidectomy under local versus general anesthesia in health camp settings in Uganda: a protocol for randomized prospective equivalence single-blind controlled trial.

BACKGROUND: Endemic goiter is highly prevalent in Uganda at 60.2%, contributing to the high surgical burden. While compelling evidence suggest that in selected cases, thyroidectomy under local anesthesia (LA) is associated with fewer post-operative complications, low costs, and short hospital stays, local anesthesia is not considered a priority technique for thyroidectomy in resource-constrained settings such as Uganda, despite having fewer general anesthesia (GA) and critical care providers. The objective of this trial is to compare euthyroidectomy under local versus general anesthesia among patients with grade 1-2 uncomplicated euthyroid goiter in Uganda. METHODS: This prospective equivalence randomized, single-blind controlled trial protocol will be conducted among eligible participants with grade 1-2 uncomplicated euthyroid goiters. The recruitment processes will start in October 2022 and end in April 2023. Consenting participants with an indication for thyroidectomy will be randomized into two arms of 29 participants in each arm during the Bulamu Health Care Organization surgical camps in Uganda. DISCUSSION: The primary outcome of this trial protocol is to compare the early post-operative complications of euthyroidectomy done under LA versus GA. The outcome variables include post-operative pain based on visual analogue scale, nausea, vomiting, hematoma formation, and transient voice changes determined at an interval of 6, 12, and 24 h and at 30 days. In addition, we shall compare the surgical site infection rates, procedure costs, hospital stay, and patients' level of satisfaction based on a 5-point Likert scale and their willingness to undergo a similar surgery using the same anesthetic technique between the two groups. We hypothesize that euthyroidectomy under LA could potentially offer similar benefits as GA, reduce costs related to procedure, complications, and hospital stay while at the same time mitigating the unmet need for surgery attributable to shortage of general anesthesia providers and critical care facilities in low-income settings. TRIAL REGISTRATION: Pan African Clinical Trial Registry PACTR202208635457430. Registered on 11th August 2022. All items from the WHO trial registration data set are within the protocol.

General Anesthesia Versus Local Anesthesia in Patients Undergoing Transcatheter Aortic Valve Replacement: An Updated Meta-Analysis and Systematic Review.

OBJECTIVES: For patients with aortic stenosis, transcatheter aortic valve replacement (TAVR) offers a less invasive treatment modality than conventional surgical valve replacement. Although the surgery is performed traditionally under general anesthesia (GA), recent studies have described success with TAVR using local anesthesia (LA) and/or conscious sedation. The study authors performed a pairwise meta-analysis to compare the clinical outcomes of TAVR based on operative anesthesia management. DESIGN: A random effects pairwise meta-analysis via the Mantel-Haenszel method. SETTING: Not applicable, as this is a meta-analysis. PARTICIPANTS: No individual patient data were used. INTERVENTIONS: Not applicable, as this is a meta-analysis. MEASUREMENTS AND MAIN RESULTS: The authors comprehensively searched the PubMed, Embase, and Cochrane databases to identify studies comparing TAVR performed using LA or GA. Outcomes were pooled as risk ratios (RR) or standard mean differences (SMD) and their 95% CIs. The authors' pooled analysis included 14,388 patients from 40 studies (7,754 LA; 6,634 GA). Compared to GA TAVR, LA TAVR was associated with significantly lower rates of 30-day mortality (RR 0.69; p < 0.01) and stroke (RR 0.78; p = 0.02). Additionally, LA TAVR patients had lower rates of 30-day major and/or life-threatening bleeding (RR 0.64; p = 0.01), 30-day major vascular complications (RR 0.76; p = 0.02), and long-term mortality (RR 0.75; p = 0.009). No significant difference was seen between the 2 groups for a 30-day paravalvular leak (RR 0.88, p = 0.12). CONCLUSIONS: Transcatheter aortic valve replacement performed using LA is associated with lower rates of adverse clinical outcomes, including 30-day mortality and stroke. No difference was seen between the 2 groups for a 30-day paravalvular leak. These results support the use of minimally invasive forms of TAVR without GA.

A comparison of the success rate of pneumatic reduction in intussusception between general anesthesia and deep sedation: a randomized controlled trial.

PURPOSE: This study was aimed to compare the success rate between patients who underwent general anesthesia and deep sedation. METHODS: Patients who were diagnosed with intussusception and had no contraindications would receive non-operative treatment first by undergoing pneumatic reduction. The patients were then split in to two groups: one group underwent general anesthesia (GA group), while the other underwent deep sedation (SD group). This study was a randomized controlled trial which compared success rate between two groups. RESULTS: A total of 49 episodes diagnosed with intussusception were random into 25 episodes in GA group and 24 episodes in SD group. There was no significant difference in baseline characteristic between the two groups. The success rates of GA group and SD group were equally 88.0% (p = 1.00). Sub-analysis of the success rate was lower in the patients with high-risk score for failed reduction. (Chiang Mai University Intussusception (CMUI) failed score in success VS failed = 6.9 ± 3.2 vs. 10.3 ± 3.0 p = 0.017). CONCLUSION: General anesthesia and deep sedation offered similar success rates. In cases of high risk of failure, general anesthesia should be considered to accommodate the switch to surgical management in the same setting if the non-operative approach fails. The appropriate treatment and sedative protocol also increase the success of reduction.

Pain-related complaints of paediatric patients after dental treatment under general anaesthesia.

AIM: To identify factors related to postoperative pain and to recognise strategies to reduce this pain after dental treatment under general anaesthesia. METHODS: Cross-sectional observational study. Children treated under general ansesthesia reported pain daily using the Wong Baker FACES® Pain Rating Scale. Their parents/caregivers filled in a related Yes/No questionnaire during hospitalisation and the first postoperative week. The duration and severity of pain were evaluated in relation to various factors. CONCLUSION: A well-established protocol is indicated to reduce operation time. Patients and their parents should be informed about the possibility of constantly subsiding postoperative pain that may last for a week. As additional local anaesthesia during general anaesthesia (GA) does not provide postoperative pain reduction in deciduous tooth extraction cases, its administration could be omitted.

Comparison of general and regional anesthesia on short-term complications in patients undergoing total knee arthroplasty: A retrospective study using national health insurance service-national sample cohort.

This retrospective study compared the mortality and short-term complications according to the choice of general anesthesia or regional anesthesia in patients who underwent a total knee arthroplasty (TKA). We searched the Korean National Health Insurance Service National Sample Cohort database to analyze data from patients who received a TKA between January 2002 and December 2015. Before comparing the general and the regional anesthesia groups, the bias was reduced by propensity score matching. After matching, the mortality and complications occurring within 30 days after a TKA were compared between the 2 groups. In the database, 6491 primary TKA cases were identified. Nine hundred forty-three patients (14.5%) had a TKA performed under general anesthesia, and 5548 (85.5%) had a TKA performed under regional anesthesia. After propensity score matching, the data of 1886 patients were analyzed, with 943 patients in each group. There was no significant difference in mortality (0.32% vs 0.00%), transfusion rate (84.52% vs 84.73%, P = .8989), and length of hospital stay (50 vs 53, P = .5391) between the general and regional anesthesia groups. Most of the complications were not significantly different, but the major complications, including myocardial infarction (1.70% vs 0.64%, P = .0414) and acute renal failure (0.85% vs 0.11%, P = .0391), were higher in the general anesthesia group than in the regional anesthesia group. Also, admission to the intensive care unit (8.48% vs 2.33%, P < .0001) and total cost (₩8067, 400 vs ₩7487, 940, P = .0002) were higher in the general anesthesia group than in the regional anesthesia group. Our study found that regional anesthesia for TKA is associated with a decrease in major complications, including myocardial infarction and acute renal failure, and medical costs.

Hypnosis as an alternative to general anaesthesia for paediatric superficial surgery: a randomised controlled trial.

BACKGROUND: Reducing perioperative anxiety and controlling pain in children are essential to optimise recovery and outcomes for both children and their parents. By acting on sensory and affective modulation of anxiety and pain, hypnosis is widely used in medical care, especially in anaesthesia. This randomised controlled clinical trial was designed to compare general anaesthesia and intraoperative hypnosis support for perioperative management of children undergoing superficial surgery. METHODS: Children aged 7-16 yr scheduled for day-case superficial surgery were included and randomly assigned to one of the following two groups: general anaesthesia group or hypnosis group. The primary outcome was length of hospital stay. Child and parent anxiety, child pain, and the occurrence of postoperative negative behavioural changes were also evaluated. RESULTS: Sixty children of mean age 10.3 (standard deviation: 2.6) yr were enrolled in the study. Hypnosis was successful in all but one case. The median (25th-75th percentile) length of hospital stay was shorter in the hypnosis group (120 [95-145] vs 240.5 [218-275] min; P<0.001). The general anaesthesia group was associated with a greater incidence of high levels of preoperative anxiety in children (30 vs 11%; P=0.001) and parents (55 vs 30%; P=0.05). Pain scores did not differ between groups. No negative postoperative behavioural changes were reported. CONCLUSIONS: In children aged 7-16 yr, hypnosis appears to be feasible and accepted. The quality of the perioperative experience and the rapid recovery support the use of hypnosis as an effective and safe alternative to general anaesthesia for paediatric superficial surgery. CLINICAL TRIAL REGISTRATION: NCT02505880.

[Intraoperative management of potentially fatal arrhythmias after anesthesia induced by severe hypokalemia: A case report].

Severe hypokalemia is defined as the concentration of serum potassium lower than 2.5 mmol/L, which may lead to serious arrhythmias and cause mortality. We report an unusual case of potentially fatal ventricular arrhythmias induced by severe hypokalemia in a patient undergoing laparoscopic partial nephrectomy in Peking University Third Hospital due to irregular use of indapamide before operation. Indapamide is a sulfonamide diuretic with vasodilative and calcium antagonistic effects, which enhances sodium delivery to the renal distal tubules resulting in a dose-related increase in urinary potassium excretion and decreases serum potassium concentrations. The electrolyte disorder caused by the diuretic is more likely to occur in the elderly patients, especially those with malnutrition or long-term fasting. Hence, the serum potassium concentration of the patients under indapamide therapy, especially elderly patients, should be monitored carefully. Meanwhile, the potassium concentration measured by arterial blood gas analysis is different from that measured by venous blood or laboratory test. According to the previous research, the concentration of potassium in venous blood was slightly higher than that in arterial blood, and the difference value was 0.1-0.5 mmol/L. This error should be taken into account when rapid intravenous potassium supplementation or reduction of blood potassium level was carried out clinically. In the correction of severe hypokalemia, the standard approach often did not work well for treating severe hypokalemia. The tailored rapid potassium supplementation strategy shortened the time of hypokalemia and was a safe and better treatment option to remedy life-threatening arrhythmias caused by severe hypokalemia with a high success rate. Through the anesthesia management of this case, we conclude that for the elderly patients who take indapamide or other potassium excretion diuretics, the electrolyte concentration and the general volume state of the patients should be comprehensively measured and fully evaluated before operation. It may be necessary for us to reexamine the serum electrolyte concentration before anesthesia induction on the morning of surgery in patients with the history of hypokalemia. For severe hypokalemia detected after anesthesia, central venous cannulation access for individualized rapid potassium supplementation is an effective approach to reverse the life-threatening arrhythmias caused by severe hypokalemia and ensure the safety of the patients.

Tumescent local anesthesia versus general anesthesia for subcutaneous implantable cardioverter-defibrillator implantation: A cost-effectiveness analysis.

BACKGROUND: General anesthesia (GA) is the standard anesthetic approach for subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation. Nonetheless, GA is expensive and can be associated with adverse events. Tumescent local anesthesia (TLA) has been shown to reduce in-room and procedural times and to decrease post-procedural pain, all of which could result in a reduction in procedure-related costs. OBJECTIVE: The purpose of this study is to compare the cost-effectiveness of GA and TLA in patients undergoing S-ICD implantation. METHODS: The present study is a prospective, nonrandomized, controlled study of patients who underwent S-ICD implantation between 2019 and 2022. Patients were allocated to either the TLA or the GA group. We performed a cost analysis for each intervention. As an effectiveness measure, the 0-10 point Numeric Pain Rating Scale at 1, 12, and 24 hours post-implantation was analyzed and compared between the groups. A score of 0 was considered no pain; 1-5, mild pain; 6-7, moderate pain; and 8-10, severe pain. Cost-effectiveness was calculated using incremental cost-effectiveness ratios. RESULTS: Seventy patients underwent successful S-ICD implantation. The total cost of the electrophysiology laboratory was higher in the GA group than in the TLA group (median ± interquartile range US$55,824 ± US$29,411 vs US$37,222 ± US$24,293; P < .001), with a net saving of $20,821 when compared with GA for each S-ICD implantation. There was a significant decrease in post-procedural pain scores in the TLA group when compared with the GA group (repeated measures analysis of variance, P = .009; median ± interquartile range 0 ± 3 vs 0 ± 5 at 1 hour, P = .058; 3 ± 4 vs 6 ± 8 at 12 hours, P = .030; 0 ± 4 vs 2 ± 6 at 24 hours, P = .040). CONCLUSION: TLA is a more cost-effective alternative to GA for S-ICD implantation, with both direct and indirect cost reductions. Importantly, these reduced costs are associated with reduced postprocedural pain.

General anaesthetic vs local anaesthetic myringoplasties: a systematic review and meta-analysis.

AIMS: To assess all available data and determine the success rates and tolerability of local anaesthetic myringoplasty in comparison with those undertaken under general anaesthetic myringoplasty. MATERIALS AND METHODS: The study was designed following a PRISMA-P protocol and registered with the PROSPERO database. MEDLINE, Cochrane Library (CDSR/Central), EMBASE and CINHAL-were directly searched for studies, which met the inclusion criteria. OBJECTIVES: Primary objective was to compare perforation closure rates between patients undergoing myringoplasty under local anaesthetic and those under general anaesthetic from all available published data. Secondary outcomes include complications, such as 'any minor complications', infection rates in the first 6 month post-op, facial nerve weakness, dysgeusia and patient satisfaction. RESULTS: 27 studies were included in the final analysis and found that myringoplasty had an overall perforation closure rate of 89%. The pooled proportion of closures after myringoplasty under local anesthesia was 87% and for myringoplasties under general anesthesia was 91%. Analysis of myringoplasty under local anaesthesia focusing on 'in-office' performed procedures only, found a closure rate of 88%. CONCLUSIONS: There is no significant difference in the success rate of myringoplasty surgery when performed under local or general anaesthetic as measured by perforation closure rates. However, there are other factors, which can drive choosing local anaesthetic surgery, such as minimising anaesthetic risks, reducing costs and reducing environmental impact.

Effect of acupuncture at Shuitong and Shuijin points on sufentanil-induced cough in general anesthesia induction: a randomized controlled trial. / é’ˆåˆºæ°´é€šã€æ°´é‡‘ç©´å¯¹å ¨èº«éº»é†‰è¯±å¯¼æœŸèˆ’èŠ¬å¤ªå°¼è¯±å‘å‘›å’³çš„å½±å“ï¼šéšæœºå¯¹ç §è¯•éªŒ.

OBJECTIVES: To observe the therapeutic effect of acupuncture at Shuitong and Shuijin points on preventing sufentanil-induced cough and its influence on hemodynamics in general anesthesia induction. METHODS: A total of 80 patients scheduled for elective surgery undergoing general anesthesia were randomly divided into an observation group (40 cases) and a control group (39 cases,1 case eliminated). In the control group, the routine anesthesia was performed,with intravenous injection of 1% sufentanil citrate 0.5 µg/kg, 1% propofol (total amount was calculated according to 2 mg/kg) and cisatracurium besilate 0.2 mg/kg. In the observation group, before routine anesthesia induction, acupuncture was applied to Shuitong and Shuijin points on the right and the needles were retained for 30 min. During anesthesia induction, the complications i.e. cough and chest wall stiffness were observed, and the systolic blood pressure (SBP), heart rate (HR) and pulse oxygen saturation (SpO2) were monitored 5 min after the patients entered the operation room (T0),at the moment of intravenous injection of sufentanil (T1) and 2 min after sufentanil injection (T2) , 1 min before and after endotracheal intubation (T3,T4) of the two groups, respectively. RESULTS: During anesthesia induction,the condition of mild, moderate and severe cough in the observation group was superior to that of the control group (P<0.05), the total cases of cough and its total incidence were lower than those of the control group (P<0.05). Two cases of chest wall stiffness were present in each group, but without statistical difference between the two groups (P>0.05). In comparison of SBP, HR and SpO2 at T0, T1, T2, T3 and T4, the differences were not significant statistically between the two groups (P>0.05). SBP and HR increased at T2 when compared with those at T1 in the control group (P<0.05), but there was no statistical difference in SpO2 (P>0.05); while, the differences in SBP, HR and SpO2 were not significant at T2 when compared with those at T1 in the observation group (P>0.05). CONCLUSIONS: Acupuncture at Shuitong and Shuijin points can effectively prevent from sufentanil-induced cough, reduce the severity of cough and stabilize the hemodynamic indicators.

Electroacupuncture as an effective therapy for Tapia's syndrome after transoral intubation for general anesthesia: a case report and review of the literature.

BACKGROUND: Tapia's syndrome is a rare complication of airway manipulation under general anesthesia. Injuries to the vagus nerve (X) and hypoglossal nerve (XII) during transoral intubation are the primary cause of the disease. The typical symptoms include hoarseness, dysarthria, dysphagia, tongue muscle atrophy, and tongue deviation toward the affected side. We report a case of Tapia's syndrome treated with electroacupuncture to accelerate the recovery process, and discuss the potential mechanism behind our findings based on previous research. CASE PRESENTATION: In this report, we describe a 57-year-old Chinese man who suffered Tapia's syndrome after craniotomy evacuation of hematoma with general anesthesia and transoral intubation. After 52 days of electroacupuncture therapy along with standard swallowing training, the patient achieved significant improvement in deglutition and speech function. CONCLUSION: Electroacupuncture is effective and safe for Tapia's syndrome. It can shorten the recovery time when combined with routine swallowing rehabilitation.

Regional and neuraxial anaesthesia techniques for spinal surgery: a scoping review.

BACKGROUND: Whilst general anaesthesia is commonly used to undertake spine surgery, the use of neuraxial and peripheral regional anaesthesia techniques for intraoperative and postoperative analgesia is an evolving practice. Variations in practice have meant that it is difficult to know which modalities achieve optimal outcomes for patients undergoing spinal surgery. Our objective was to identify available evidence on the use of regional and neuraxial anaesthesia techniques for adult patients undergoing spinal surgery. METHODS: This study was conducted using a framework for scoping reviews. This included a search of six databases searching for articles published since January 1980. We included studies that involved adult patients undergoing spinal surgery with regional or neuraxial techniques used as the primary anaesthesia method or as part of an analgesic strategy. RESULTS: Seventy-eight articles were selected for final review. All original papers were included, including case reports, case series, clinical trials, or conference publications. We found that general anaesthesia remains the most common anaesthesia technique for this patient cohort. However, regional anaesthesia, especially non-neuraxial techniques such as fascial plane blocks, is an emerging practice and may have a role in terms of improving postoperative pain relief, quality of recovery, and patient satisfaction. In comparison with neuraxial techniques, the popularity of fascial plane blocks for spinal surgery has significantly increased since 2017. CONCLUSIONS: Regional and neuraxial anaesthesia techniques have been used both to provide analgesia and anaesthesia for patients undergoing spinal surgery. Outcome metrics for the success of these techniques vary widely and more frequently use physiological outcome metrics more than patient-centred ones.

A Case of Wide QRS Tachycardia After the Local Administration of Epinephrine to Reduce Bleeding During General Anesthesia.

We report a case of wide QRS tachycardia or ventricular tachycardia with a pulse after the administration of epinephrine under general anesthesia. After induction and achieving a sufficiently deep plane of general anesthesia, gauze soaked in a 1:100,000 epinephrine solution was applied to the patient's nasal mucosa and 1% lidocaine with 1:100,000 epinephrine was administered via intraoral infiltration. Several minutes after the start of surgery, the patient's blood pressure and heart rate suddenly increased and a wide QRS tachycardia was observed on the electrocardiogram, which then reverted to a normal sinus rhythm. According to the past reports, similar arrhythmias have occurred after administration of epinephrine in the head and neck. These findings suggest that anesthesia providers must be aware of the risks associated with epinephrine and local anesthetic use, particularly in the head and neck region.

Battlefield Acupuncture Use for Perioperative Anesthesia in Veterans Affairs Surgical Patients: A Single-Center Randomized Controlled Trial.

Introduction: The risks from opioid use are well known in and mandate nonpharmacological modalities for the management of postoperative pain. The aim of this study was to investigate the effectiveness of battlefield acupuncture (BFA) as an adjunct therapy for postoperative pain in U.S. veteran patients undergoing major surgery under general anesthesia. Methods: Patients undergoing major surgery performed under general anesthesia from June 2017 to June 2018 were enrolled in the study. Patients were randomly assigned to receive either BFA or sham acupuncture. Outcomes such as pain intensity measured by visual analog scale score, opioid consumption, and the incidence of analgesia-related adverse effects were compared between the study groups. Results: A total of 72 subjects were included in this study (36 subjects in each study group). The median 24-h opioid postoperative consumption measured in morphine milligram equivalent (MME) was lower in the BFA group compared to the sham acupuncture group (18.3 [±12.2] MME vs. 38.6 [±15.9] MME, p < 0.001). Pain intensity reported by patients at 6, 12, 18, and 24 h postoperatively was lower in the BFA group compared to the sham acupuncture group. The incidence of postsurgical nausea and vomiting was lower in patients receiving BFA compared to patients receiving sham acupuncture. There were no intergroup differences in terms of postoperative anxiety or hospital length of stay. Conclusion: The results from this study reveal the potential clinical benefits of using BFA for reducing pain intensity and opioid requirements in surgical patients.
