Management of Square Carcinoma of the Lower Lip Using Camille-Bernard Flap under Local Anesthesia: When Constraints Dictate Our Attitude

Introduction: Squamous cell carcinomas of the lip essentially pose a therapeutic management problem. In the West, their treatment is done under general anesthesia and follows the classic rules of oncology. In our context of exercise, we sometimes have a different attitude dictated by various constraints. Observation: 55-year-old patient with no notable history, seen in consultation for a very large ulcerative-budding lesion on the right 2/3 of the lower lip with mucocutaneous involvement without lymph node findings found on examination. Faced with this suspicious lesion and the patient’s financial difficulties, we decided to operate under local anesthesia to remove this tumor. The oncological excision was followed by immediate plasty using a Camille-Bernard flap with a good immediate aesthetic and functional result and postoperative day 7. The patient was unable to take his surgical specimen to anatomy-pathology and was lost to follow-up due to lack of financial resources. On anatomo-pathological analysis of the surgical specimen, the margins were healthy with confirmation of squamous cell carcinoma (anapathological reading made for scientific interest). Discussion: The particular mentality of certain patients and their difficult financial conditions push us to have an unconventional therapeutic attitude in oncology, but which nevertheless makes it possible to resolve certain problems that we often face. Local anesthesia is possible and realistic in cases like ours and the results can be acceptable and life-saving.

Cure of Varicocele under Local Anesthesia: Impact on Sperm Parameters

Introduction: Varicocele is one of the most frequent causes of infertility. There are several therapeutic modalities, namely surgery (open and laparoscopic) and conventional radiology. The aim of our study was to evaluate the impact of a varicocele cure under local anaesthesia on spermogram quality. Material and Methods: We conducted a retrospective descriptive study from 1 January 2022 to 31 December 2023 in the urology department of the Hôpital Militaire de Ouakam (HMO). The parameters studied were age, reasons for consultation, time to urology consultation, grade of varicocele, Doppler ultrasound and spermogram data before treatment and 3 months after treatment. Treatment consisted of bilateral subinguinal varicocelectomy under local anaesthetic. Data were entered and analysed using Excel software version 2021. Results: We studied 41 patients. The mean age of the patients was 35.3 ± 6.9 years, with extremes of 22 and 50 years. Thirty-eight of our patients (88.37%) were married. The most frequent reason for consultation was primary infertility (72.09%). 28 patients (68.3%) had a bilateral varicocele on ultrasound. Varicocele was associated with bilateral testicular hypotrophy in 13 patients (31.7%) and unilateral left testicular hypotrophy in 11 patients (26.8%). All patients underwent subinguinal varicocelectomy under local anaesthetic. Mean follow-up was 4.5 months. A clear statistically significant improvement was noted in sperm motility and concentration in postoperative spermograms, with normalisation of the spermogram in 15 (36.5%) of patients. Conclusion: The impact of varicocele on sperm parameters has been clearly established. There are various therapeutic methods for curing varicocele, including varicocelectomy under local anaesthetic, which, in addition to its undeniable economic advantages, can significantly improve sperm parameters in patients with varicocele and prevent their deterioration over time.

General anesthesia versus local anesthesia for penetrating keratoplasty: a prospective study

AIM:To examine which anesthesia general or local is more effective for penetrating keratoplasty(PKP).METHODS:Patients with indications for PKP(n=141)were enrolled in a prospective study and randomly divided into general anesthesia group(group A,70 eyes)and local anesthesia group(group B,71 eyes).Patients received optical PKP(group A1,30 eyes;group B1,30eyes)or therapeutic PKP(group A2,40 eyes;group B2,41 eyes).Measurement of anterior chamber treatment time(T)for PKP patients and the ratio(R)of the area of the pupils to that of recipient graft region.T and R values,as well as perioperative and postoperative complications,were compared between groups A and B using t-test orχ2test.RESULTS:Patients were followed for 2wk after PKP.T was(13.45±8.64)min for group A and(7.36±5.24)min for group B,a statistically significant difference(P【0.001).The R value for group A was stable during the operation,while for PKP patients in group B the value initially increased then gradually decreased to normal after suturing.In group B,extrusion of intraocular contents occurred in 5 eyes,and iridal prolapse occured in 11cases;no perioperative complications occurred in group A.Relapse rate for fungal keratitis was 13.04%in group B and 0%in group A.CONCLUSION:Under general anesthesia,pupils remaine stable during PKP and perioperative complications are averted.General anesthesia gives more time to treat pathological changes in the anterior chamber and treatment success rate is higher.

Bloodless Outpatient Surgical Treatment of Rectocele and Cystocele under Local Anesthesia

Background: Surgical treatment of rectocele and cystocele is usually performed in a hospital setting under regional (spinal or epidural) or general anesthesia, and patients commonly have to stay in the hospital for at least one or two days. The possibility of performing the surgery under local anesthesia, as an outpatient procedure with minimal bleeding and pain, no surgical assistants, with immediate discharge and, most importantly, without compromising postoperative results, is appealing. To our knowledge, no studies have evaluated whether performing rectocele and/or cystocele rectocele repair under local infiltration anesthesia and without separation of the vaginal mucosa from the underlying fascia achieves these goals. Objective: The aim of this study is to describe a new surgical technique for outpatient treatment of cystocele and rectocele under local anesthesia, and our initial results. Materials and Methods: Forty women underwent outpatient surgical repair of rectocele and/or cystocele between April and September 2020 at the ambulatory procedure room of the authors’ clinics. The technique consists of a triangular-shaped CO2 laser vaporization or electrocauterization of the posterior and/or anterior vaginal epithelium, followed by plication of the edges of the triangle with 0 polygalactin suture. A perineorrhaphy was always performed concomitantly with rectocele repair, and a transobturator sling was performed in women presenting with concomitant stress urinary incontinence. Postoperative evaluation included POP-Q measurement for each patient six months after the procedure, and resolution of prolapse was considered when anterior and/or posterior vaginal wall presented as stage 0 or 1. Pre and postoperative POP-Q measurements were analyzed using Wilcoxon signed-rank test. Results: The mean operating time was 21 minutes (range: 14 - 38 minutes). All patients tolerated the procedure well and were discharged immediately afterwards. There were no intraoperative or postoperative complications, and all patients had satisfactory healing of the vaginal mucosa. Bleeding from the rectocele and/or cystocele repair was minimal, and nobody required extra-anesthesia or transfer to a hospital surgical theater. At six month follow-up, pre and postoperative POP-Q measurements of points Ap, Bp, Aa and Ba were all statistically significant (Ap 1.6 ± 1.2 × -2.4 ± 0.9, Bp 2.6 ± 1.6 × -2.7 ± 1.4, Aa 1.4 ± 1.1 × -2.3 ± 0.8, and Ba 2.4 ± 1.5 × -2.5 ± 1.2) respectively, revealing satisfactory resolution of both rectocele and cystocele. Conclusion: Our initial results suggest that rectocele and cystocele may be safely and effectively treated under local anesthesia in an outpatient setting using this new technique.

Inguinal Hernia Repair with Local Anesthesia in the Outpatient—10 Year Experience

Objective: To demonstrate the feasibility of inguinal hernia repair with local anesthesia in an out-patient regime, with safety, efficacy and short learning curve. Methods: We prospectively evaluated 1186 patients undergoing inguinal hernia repair under local anesthesia on an outpatient basis between November 2004 and March 2014. Of the total number of hernias surgically treated in this period, 755 were operated on the right, 394 on the left and 37 bilateral. We used clinical, surgical and psychosocial criteria for inclusion in the procedure. The parameters for exclusion were complex, irreducible or recurrent hernia, obesity (BMI greater than 30 kg/m2), patient’s refusal and psychiatric disorder. All patients underwent elective surgery and were analyzed regarding surgical outcome, complications and hospital stay. Results: All operations were completed successfully. In no case there was a need to change the anesthetic method. Surgical time was similar to that conducted with other methods of anesthesia and there were no cases of adverse effects of local anesthetics. Intra-operative complications amounted to approximately 2.64%. There was no need for hospital admissions greater than 24 hours. Conclusion: The procedure is feasible and causes no perioperative significant pain, is safe, can be performed by residents under supervision, has satisfactory patient acceptance and complications similar to those observed in a conventional herniorrhaphy, allowing lower time and cost of hospitalization and faster access to treatment.

Comparison of perceived pain and patients’ satisfaction with traditional local anesthesia and single tooth anesthesia: A randomized clinical trial

BACKGROUND Contemporary innovations in the area of local anesthesia have attempted to provide an absolutely pain free experience for patients.Since the introduction of Computer-Controlled Local Anesthetic Delivery Systems to dentistry,many studies have compared its efficacy and safety to conventional anesthesia.However,very few studies have compared single tooth anesthesia(STA)and traditional local anesthesia.AIM To compare pain rating,changes in blood pressure,and heart rate during the local anesthetic injection.The secondary objectives were to measure the patients’level of satisfaction and the differences in anesthetic efficiency between the STA system and traditional local infiltration.METHODS A randomized controlled trial was conducted and a total of 80 patients with dental restorative needs were enrolled for the study.The patients were evaluated for their general physical status and oral clinical findings before enrollment.Information regarding perceived pain,changes in heart rate and blood pressure,and patients’satisfaction was collected using an electronic data form and was analyzed using paired and unpaired t-tests.RESULTS No significant difference was noted in perceived pain(P=0.59)and systolic blood pressure(P=0.09)during anesthetic injection using both traditional and STA techniques.STA patients had a significantly higher heart rate during anesthesia,although a statistically significant difference was noted among the traditional anesthesia and the STA groups even before anesthesia.During the restorative procedure,less pain was perceived by STA patients on the Wong-Baker FACES pain scale,which was statistically significant(P<0.001).Analyses of post-procedure patient responses showed that STA patients had a significantly better treatment experience and preferred to have the same method of injection in the future(P=0.04).CONCLUSION STA system can provide less painful and more comfortable restorative treatment procedures in comparison to the traditional infiltration technique.

Breast Conserving Surgery and Sentinel Lymph Node Biopsy under Local Anesthesia for Breast Cancer

Background: Breast conserving surgery and sentinel lymph node biopsy has become the standard operation for early breast cancer. This operation has been performed under local anesthesia for patients that would like short-term admission or for those not indicated for general anesthesia due to complications. This report presents the outcomes of breast conserving surgery and sentinel lymph node biopsy under local anesthesia. Patients and Methods: The study included 61 patients with breast cancer that were all definitely diagnosed before surgery. The indications were preoperatively diagnosed localized DCIS, invasive carcinoma measuring less than 3 cm in tumor diameter on ultrasound, and tumors with negative axillary lymph nodes. The surgical procedures included breast conserving surgery associated with sentinel lymph node navigation biopsy. Results: The surgery could be performed under local anesthesia in all 61 patients, and no patient was converted to general anesthesia. Four patients had sentinel lymph node metastasis. Surgical stumps were positive in 18 patients (29.5%). Ten Gy of boost irradiation of the tumor bed was added to the conventional breast irradiation for these patients. There were no serious complications associated with surgery. Conclusion: Breast conserving surgery and sentinel lymph node biopsy for early breast cancer can be performed safely under local anesthesia. This procedure contributes to shortening the length of hospitalization and thereby saving medical resources without deceasing the quality of treatment.

Tubal Ligation under Local Anesthesia in a Country with Limited Resources: 56 Cases of Wife and Husband’s Experience in the Gynecology-Obstetrics Department of Ignace Deen National Teaching Hospital, Conakry, Guinea

Tubal ligation is a surgical sterilization procedure that provides permanent and reliable contraception to women.?Tubal obstruction is a method of permanent birth control that can be performed after mini-laparotomy under local anesthesia. Objective:?To determine the outcome of tubal sterilizations by mini-laparotomy under local anesthesia performed in clients who underwent the surgical operation in the Maternity Ward of Ignace Deen National Hospital. Patients and Methods:?The Gynecology and Obstetrics Department of Ignace Deen National Hospital was used as the place for the study. The study involved all the women seeking voluntary surgical contraception. This was a retrospective study of a descriptive type carried out from January 1, 2017 to December 31, 2018. A consent form was filled out and signed by spouses after an interview and a systematically carried out pre-operative clinical and para-clinical assessment. Results:?During the study period, 56 tubal ligations were performed i.e. 4.72 percent of all family planning methods. The recruiting for the surgical contraception involved clients whose typical profile is that of women with an average age of 35, mostly housewives (35.71%), major multiparous (69.63%) with 6 living children on average. Married women made up the bulk of the recruiting i.e. 96.44%. Unmarried women made much more use of other methods. Indications of personal convenience were the most frequently encountered common reason. Among medical causes, high blood?pressure concerned the majority of cases: 38% of the indications. Surgical contraception in between was more practiced than the post-partum one. The recorded complication was the parietal hematoma due to a lack of hemostasis and it accounted for 1.79% of cases. The progress was uncomplicated in?98.68% of cases. Forty couples (71.42%) expressed their feelings of satisfaction against only 6 cases of regret (10.71%). Conclusion:?The surgical contraception has become a requirement for modern couples. Tubal ligation by?mini-laparotomy is a simple operation and a harmless method of contraception that allows clients to use permanent contraception. Carried out on an outpatient basis, incidents and accidents are rare and may have psychological repercussions that are difficult to assess. The technical mastery of the gesture helps to minimize these incidents.

Lidocaine hydrochloride loaded isomaltulose microneedles for efficient local anesthesia of the skin

Lidocaine hydrochloride(LIDH) as an anesthetic is widely used in local anesthesia. Dissolving microneedles(MNs) have great application value in the field of skin anesthesia. However, the limited drug-loading of dissolving MNs is an existing challenge that affects clinical use. In this study, we have screened isomaltulose(ISO) as the proper matrix material for the MNs by using molecular dynamics(MD) simulation. Our findings indicate that ISO has good compatibility with LIDH, and the LIDH-loaded ISO MNs(LI-MNs) have high drug-loading capacity. The drug-loading capacity of LI-MNs could reach 80%, and it could effectively puncture the skin. In addition, the preparation method of customized LI-MNs was established based on three-dimensional(3D) printing technology. It was shown that the administration time of LI-MNs could be controlled within 3 min. Also, the LI-MNs were able to provide the local anesthetic efficacy within2 min and sustained for more than 2 h. Significantly, LI-MNs had more efficient drug efficacy compared to the topical creams and the majority of existing LIDH-loaded dissolving MNs. They even provided a longer duration of action than the injections. Overall, the LI-MNs with high drug-loading have a promising application prospect.

Ureteroscopy during pregnancy under local anesthesia and light sedation:Technique and video

Ureteroscopy during pregnancy has become increasingly recognized as a safe intervention.Performing it under local anesthesia and light sedation reduces the risks associated with general or regional anesthesia,such as difficult airway scenarios,hypothermia,and hypotension.In addition,this approach reduces the total amount of fetal exposure to medications and anesthetic agents.Performing ureteroscopy in this manner requires a number of adjustments and modifications to the standard technique.This article provides a summary in a step-by-step format,as well as an accompanying video demonstration.

Rapidly separable bubble microneedle patch for effective local anesthesia

In cutaneous cosmetology surgery,local injection or coated anesthetics are generally used to provide analgesia at the treatment site to achieve painless operation.Due to the barrier of corneum,topical cream may cause uncertain dosage and delayed analgesia.Local injection has problems such as pain,infection,and misoperation.Therefore,it is necessary to develop a painless and rapid administration method for local anesthesia.Here,a lidocaine/hyaluronic acid bubble microneedle patch(Lido/HA bMNP)was prepared for rapid drug delivery and efficient analgesia.The bubble structure between microneedles(MNs)and the backing layer allowed the MNs to efficiently penetrate into the skin and remove from the backing layer under shear force to rapidly complete the administration.Drugs were quickly released with the dissolution of HA within 15 s,which immediately played an analgesic effect and lasted for 1 h.Lido/HA bMNP could deliver precise doses to the skin in an extremely short time,which had the advantages of convenient operation,high biosafety,rapid onset of analgesia,and reasonable pain relief time.This patch provided an alternative way for local anesthesia and it was a promising transdermal drug delivery method for the realization of high quality and efficiency“painless medical beauty”.

Influence of local anesthesia on the outcomes of non-surgical periodontal treatment

Background:There is limited evidence of the effects of local anesthesia(LA)on outcomes of non-surgical periodontal treatment(NSPT),in particular among the Chinese.This retrospective cohort study aimed to evaluate the effects of LA on short-term treatment outcomes of NSPT and to determine under what circumstances LA should be prescribed to improve these outcomes.Methods:Data from periodontal examinations of 3980 patients were used.The data were from 3-month re-evaluation records of an electronic periodontal charting record system in the Department of Periodontology of Peking University School and Hospital of Stomatology from June 2008 to January 2015.Descriptive analyses included changes in probing depth(PD)and the Mazza bleeding index(BI).Two-level(patient and tooth)logistic regression models and three-level(patient,tooth,and site)linear regression models were constructed to analyze the influence of LA on PD for all teeth/sites and teeth/sites with an initial PD≥5 mm.Decreases in PD and BI at sites under LA using the initial PD were also compared.Results:A significantly higher mean decrease in PD after NSPT was found in the LA group than in the no local anesthesia(NLA)group(0.98 vs.0.54 mm,t=24.12,P<0.001).A significantly higher probability of decreases was found in the LA group in BI(percentages of teeth with BI>1 and BI>2)for all teeth(16.7%vs.13.8%,t=3.75,P<0.001;34.7%vs.28.1%,t=6.73,P<0.001)and PD for teeth with PD≥5mm(32.3%vs.17.3%,t=28.48,P<0.001).The difference in PD between the LA and NLA groups increased as the initial PD increased.The difference between the two groups was 0.12 to 0.22 mm for sites with a baseline PD<7 mm;however,it increased to 0.41 to 1.37 mm for sites with a baseline PD≥7 mm.Conclusions:LA improved the decrease in PD after NSPT.Root debridement at sites with initial PD≥7 mm should be performed under routine LA.

In-office balloon dilation of the Eustachian tube under local anesthesia: A retrospective review

Objective:To study the effectiveness and feasibility of in office balloon dilation of the Eustachian tube(BDET)utilizing a novel anesthetic protocol.Study design:retrospective review.Methods:Retrospective chart review looking at the tolerability and effectiveness of standalone BDET in an office setting utilizing a novel topical anesthesia protocol in 33 patients with Eustachian tube dysfunction as defined by an ETDQ-7 score greater than 2.2 and type B or C tympanograms for greater than 3 months despite maximal medical management,including at least 4 weeks of nasal steroids.Results:BDET in the office was well tolerated with 94%(31/33)of patients completing the procedure as planned.No adverse effects or complications were reported;however,the planned dilation time was cut short in one case due to significant discomfort and aborted prior to dilation in another due significant coughing.Tympanograms normalized at six weeks in 87.1%(27/31)of patients who underwent dilation.Conclusion:This study demonstrates that performing BDET in an office setting utilizing a local anesthesia protocol is feasible and effective when the unique barometric considerations of BDET are addressed.

Feasibility analysis of rapid right ventricular pacing in thoracic endovascular aortic repair under local anesthesia

Background Rapid right ventricular pacing is one of the methods for counteracting the ＂wind sock＂ effect in the thoracic endovascular aortic repair （TEVAR）. Most of the doctors are to complete this operation under general anesthesia. Now, our operation has been performed under local anesthesia. No related reports were found as to whether can the patient tolerate rapid fight ventficular pacing under local anesthesia. Methods From 2009 January to 2010 January, in our hospital all the DeBakey llI aortic dissection patients who underwent TEVAR were randomly divided into general anesthesia group （n = 50） and local anesthesia group （n = 51）. All the data were compared between two groups including the hemodynamic indexes, the graft positioning accuracy, rapid pacing duration, operation time, intraoperative discomfort and postoperative neurological understanding function changes and the complications. Results The success rate were 100% in the two groups. The duration of rapid pacing, operation time, the accuracy of graft localization and the intraoperative discomfort scores of Numerical Pain Rating Scale showed no significant difference between the two groups （P 〉 0.05）. There were no rapid fight ventricular pacing-related complications in the two groups. Conclusion During thoracic endovascular aortic repair procedure, rapid fight ventricular pacing under local anesthesia is safe and feasible. Thus it is worthy to be popularized in clinical practice.

New Anesthetic Technique for Dacryocystorhinostomy: 218 Cases with Local-Anesthesia Ultrasonographic Guided and Blunt Cannula

Introduction: Epiphora is a common ophthalmologic complaint and referrals to oculoplastics and, in the presence of lower complete lacrimonasal duct obstruction, may lead to mild to severe complications, thus requiring surgery to create a new drainage path. The external dacryocystorhinostomy with silicon intubation is the surgical technique with better long-term outcomes and performed in the institutions where this study was conducted. Can be performed under either general or loco-regional anesthesia, or a combination of both. Methods: This article presents a revision of 218 consecutive cases from December 2016 to June 2021 in two specialized centers with the same standardized surgical and anesthetic technique. Results: 242 surgical prontuaries were selected, with 218 filling the inclusion criteria. 13% of the patients required additional anesthetic infusion before the beginning of the surgery;2.7% of the patients required field anesthetic infusion during the surgery and 6.4% required supplementary sedation, thus meaning a positive outcome, as the number of patients with intraoperative complaints was low, and the overall comfort was high. During the follow up, no patient required pain medication after 24 hours. Discussion: This study points towards the feasibility of the described technique in an outpatient fashion, with low, mild and tolerable side effects associated.

Malignant hyperthermia as a rare complication of local lidocaine injection:A case report

BACKGROUND Malignant hyperthermia(MH)is a hypermetabolic disorder of skeletal muscles triggered by exposure to volatile anesthetics and depolarizing muscular relaxants.It manifests with clinical presentations such as tachycardia,muscle rigidity,hyperpyrexia,and rhabdomyolysis in genetically predisposed individuals with ryanodine receptor or calcium voltage-gated channel subunit alpha1 S mutations.Local anesthetics,such as lidocaine,are generally considered safe;however,complications can arise,albeit rarely.Lidocaine administration has been reported to induce hypermetabolic reactions resembling MH in susceptible individuals.The exact mechanism by which lidocaine might trigger MH is not fully understood.Although some mechanisms are postulated,further research is needed for a better understanding of this.CASE SUMMARY We present the case of MH in a 43-year-old male patient with an unknown genetic predisposition following a lidocaine injection during a dental procedure.This case serves as a reminder that while the occurrence of lidocaine-induced MH is rare,lidocaine can still trigger this life-threatening condition.Therefore,caution should be exercised when administering lidocaine to individuals who may be susceptible to MH.It is important to note that prompt intervention played a crucial role in managing the patient’s symptoms.Upon recognizing the early signs of MH,aggressive measures were initiated,including vigorous intravenous normal saline administration and lorazepam.Due to the effectiveness of these interventions,the administration of dantrolene sodium,a specific antidote for MH,was deferred.CONCLUSION This case highlighted the significance of vigilant monitoring and swift action in mitigating the detrimental effects of lidocaine-induced MH.Caution should be exercised when administering lidocaine to individuals who may be predisposed to MH.It is very important to be aware and vigilant of the signs and symptoms of MH as early recognition and treatment intervention are important to prevent serious complications to decrease mortality.

INFLUENCE OF LOCAL INFILITRATION ANESTHESIA OF SCALP-POINT ON ACUPUNCTURE INDUCED CHANGES OF CEREBRAL BLOOD PERFUSION DETECTED BY SPECT

Objective: To observe the influence of local infiltration anesthesia at the scalp point on acupuncture stimulation induced changes of cerebral blood perfusion in the brain. Methods: Experiments were conducted in 10 healthy volunteer subjects (8 males and 2 females) who were ordered to take a lying position on a specific bed with their heads keeping in a fixed position. Scalp point used was Motor Area (MS 6). The first syringe needle (gauge 5) was inserted into the scalp from the upper 1/5 of MS 6 and the second syringe needle inserted into the scalp from the middle 2/5 of MS 6 and advanced downward, with the two needles connected to a HAN’s Therapeutic Apparatus. Images of the brain were then taken before and after electroacupuncture (EA) stimulation, and after local injection of 1% lidocaine [mixed with epinephrine (1∶200,000, 3 mL)] plus EA by using Siemens ECAM/ICON Single Photo Emission Computed Tomography (SPECT). Intravenous injection of Ethyl cysteinate dimmer 555 MBq was performed before displaying cerebral images. Data of blood functional changing rat (BFCR%) were analyzed quantitatively using a mathematic model. Results: Before EA stimulation, the blood perfusion and function of cerebral cortex, thalamus, basal ganglion and cerebellum on both sides of the brain were basically symmetry. Following EA of MS 6, BFCR% of the contralateral thalamus, parietal lobe and the frontal lobe increased significantly. Following local infiltration anesthesia, BFCR% of the contralatral thalamus declined markedly (P<0.05). The results of quantitative analysis were in agreement with those of visual observation. Conclusion: Local infiltration anesthesia of the scalp point can significantly weaken or block EA stimulation induced changes of BFCR%.
