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.

Research progress of local characteristic drugs for treatment of rheumatoid arthritis in Xinjiang

Rheumatoid arthritis(RA)is a systemic autoimmune disease characterized by synovitis.This disease tends to recur,persist,and is difficult to cure.The pathogenesis of RA is complex.Currently,the commonly used treatments for RA—non-steroidal anti-inflammatory drugs(NSAIDs),disease-modifying anti-rheumatic drugs(DMARDs),glucocorticoids,and immunosuppressants—have notable side effects with long-term use and may be ineffective for some patients.Therefore,it is crucial to find drugs with limited side effects and significant curative effects.Xinjiang's local characteristic drugs have a long history,abundant resources,and are known for their safety and effectiveness in treating RA.In recent years,many studies have reported on the mechanisms of action and therapeutic effects of Xinjiang's local characteristic drugs on RA.This article reviews the pathogenesis of RA,as well as the research progress and treatment characteristics of Xinjiang-featured drugs.

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.

Follow-up Efficacy of Integrative Chinese and Western Drugs on Localized Scleroderma with Vitamine B 6 and Xuefu Zhuyu Decoction (血府逐瘀汤)

Objective: To investigate the therapeutic effects of vitamine B 6 (Vit B 6) and Xuefu Zhuyu Decoction (血府逐瘀汤,XFZY, for activating blood circulation to remove stasis) in patients with localized scleroderma(LSD). Methods: Thirty-three patients were treated with XFZY and Vit B 6, with 15 cases taking orally prednisone acetate and 20 healthy volunteers as the control. Their level of soluble interleukin-2 receptor (sIL-2R) and tumor necrosis factor-α (TNF-α) in the patients with LSD before and after treatment were observed. Results: The level of sIL-2R and TNF-α in the serum from the patients with LSD were higher than those of healthy volunteers ( P <0.01). After treatment with Vit B 6 and XFZY, the level of sIL-2R and TNF-α from the patients with LSD decreased significantly ( P <0.01), but there were no difference between the group taking Vit B 6 plus XFZY and the group given prednisone. Conclusion: The activating blood circulation to remove stasis approach in treating LSD with integrative Chinese and Western drugs got better results, and metabolic disorder of tryptophan might be correlated with the etiology of LSD.

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%.

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.

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.

Local dose-dense chemotherapy for triple-negative breast cancer via minimally invasive implantation of 3D printed devices

Dose-dense chemotherapy is the preferred first-line therapy for triple-negative breast cancer(TNBC),a highly aggressive disease with a poor prognosis.This treatment uses the same drug doses as conventional chemotherapy but with shorter dosing intervals,allowing for promising clinical outcomes with intensive treatment.However,the frequent systemic administration used for this treatment results in systemic toxicity and low patient compliance,limiting therapeutic efficacy and clinical benefit.Here,we report local dose-dense chemotherapy to treat TNBC by implanting 3D printed devices with timeprogrammed pulsatile release profiles.The implantable device can control the time between drug releases based on its internal microstructure design,which can be used to control dose density.The device is made of biodegradable materials for clinical convenience and designed for minimally invasive implantation via a trocar.Dose density variation of local chemotherapy using programmable release enhances anti-cancer effects in vitro and in vivo.Under the same dose density conditions,device-based chemotherapy shows a higher anticancer effect and less toxic response than intratumoral injection.We demonstrate local chemotherapy utilizing the implantable device that simulates the drug dose,number of releases,and treatment duration of the dose-dense AC(doxorubicin and cyclophosphamide)regimen preferred for TNBC treatment.Dose density modulation inhibits tumor growth,metastasis,and the expression of drug resistance-related proteins,including p-glycoprotein and breast cancer resistance protein.To the best of our knowledge,local dose-dense chemotherapy has not been reported,and our strategy can be expected to be utilized as a novel alternative to conventional therapies and improve anti-cancer efficiency.

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.

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.

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.

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.

A functional tacrolimus-releasing nerve wrap for enhancing nerve regeneration following surgical nerve repair

Axonal regeneration following surgical nerve repair is slow and often incomplete,resulting in poor functional recovery which sometimes contributes to lifelong disability.Currently,there are no FDA-approved therapies available to promote nerve regeneration.Tacrolimus accelerates axonal regeneration,but systemic side effects presently outweigh its potential benefits for peripheral nerve surgery.The authors describe herein a biodegradable polyurethane-based drug delivery system for the sustained local release of tacrolimus at the nerve repair site,with suitable properties for scalable production and clinical application,aiming to promote nerve regeneration and functional recovery with minimal systemic drug exposure.Tacrolimus is encapsulated into co-axially electrospun polycarbonate-urethane nanofibers to generate an implantable nerve wrap that releases therapeutic doses of bioactive tacrolimus over 31 days.Size and drug loading are adjustable for applications in small and large caliber nerves,and the wrap degrades within 120 days into biocompatible byproducts.Tacrolimus released from the nerve wrap promotes axon elongation in vitro and accelerates nerve regeneration and functional recovery in preclinical nerve repair models while off-target systemic drug exposure is reduced by 80%compared with systemic delivery.Given its surgical suitability and preclinical efficacy and safety,this system may provide a readily translatable approach to support axonal regeneration and recovery in patients undergoing nerve surgery.

A combination therapy of ethanol injection and radiofrequency ablation under general anesthesia for the treatment of hepatocellular carcinoma

AIM: To summarize the effects of laparoscopic ethanol injection and radiofrequency ablation (L-EI-RFA), thora- coscopic (T-EI-RFA) and open-surgery assisted EI-RFA (O-EI-RFA) under general anesthesia for the treatment of hepatocellular carcinoma (HCC). METHODS: Time-lag performance of RFA after ethanol injection (Time-lag PEI-RFA) was performed in all cases. The volume of coagulated necrosis and the applied en- ergy for total and per unit volume coagulated necrosis were examined in the groups treated under general (group G) or local anesthesia (group L). RESULTS: The results showed that the total applied energy and the applied energy per unit volume of whole and marginal, coagulated necrosis were significantly larger in group G than those in the group L, resulting in a larger volume of coagulated necrosis in the group G. The rate of local tumor recurrence within one year was extremely low in group G. CONCLUSION: These results suggest that EI-RFA, un- der general anesthesia, may be effective for the treat- ment of HCC because a larger quantity of ethanol and energy could be applied during treatment under pain- free condition for the patients.

Drugs to be avoided in patients with long QT syndrome:Focus on the anaesthesiological management

Long QT syndrome incidence is increasing in general population.A careful pre-,peri-and post-operative management is needed for patients with this syndrome because of the risk of Torsades de Pointes and malignant arrhythmias.The available data regarding prevention of lethal Torsades de Pointes during anesthesia in patients with long QT syndrome is scant and conflicting:only case reports and small case series with different outcomes have been published.Actually,there are no definitive guidelines on pre-,peri-and post-operative anesthetic management of congenital long QT syndrome.Our review focuses on anesthetic recommendations for patients diagnosed with congenital long QT syndrome furnishing some key points for preoperative optimization,intraoperative anesthetic agents and postoperative care plan,which could be the best for patients with c-long QT syndrome who undergo surgery.

Locally advanced rectal cancer:The importance of a multidisciplinary approach

Rectal cancer accounts for a relevant part of colorectal cancer cases,with a mortality of 4-10/100000 per year.The development of locoregional recurrences and the occurrence of distant metastases both influences the prognosis of these patients.In the last two decades,new multimodality strategies have improved the prognosis of locally advanced rectal cancer with a significant reduction of local relapse and an increase in terms of overall survival.Radical surgery still remains the principal curative treatment and the introduction of total mesorectal excision has significantly achieved a reduction in terms of local recurrence rates.The employment of neoadjuvant treatment,delivered before surgery,also achieved an improved local control and an increasedsphincter preservation rate in low-lying tumors,with an acceptable acute and late toxicity.This review describes the multidisciplinary management of rectal cancer,focusing on the effectiveness of neoadjuvant chemoradiotherapy and of post-operative adjuvant chemotherapy both in the standard combined modality treatment programs and in the ongoing research to improve these regimens.

Effect of clonidine on the cutaneous silent period during spinal anesthesia

AIM To investigate the effect of clonidine on the cutaneous silent period(CSP) during spinal anesthesia. METHODS A total of 67 adult patients were included in this randomized, prospective, single-center, double-blind trial. They did not have neurological disorders and were scheduled for inguinal hernia repair surgery. This trial was registered on ClinicalTrials.gov(NTC03121261). The patients were randomized into two groups with regards to the intrathecally administered solution:(1) 15 mg of 0.5% levobupivacaine with 50 μg of 0.015% clonidine, or(2) 15 mg of 0.5% levobupivacaine alone. There were 34 patients in the levobupivacaine-clonidine(LC) group and 33 patients in the levobupivacaine(L) group. CSP and its latency were measured four times: prior to the subarachnoid block(SAB), after motor block regression to the 0 level of the Bromage scale, with ongoing sensory blockade, and both 6 and 24 h after SAB.RESULTS Only data from 30 patients in each group were analyzed. There were no significant differences between the groups investigated preoperatively and after 24 h. The CSP of the L group at the time point when the Bromage scale was 0 was 44.8 ± 8.1 ms, while in the LC group it measured 40.2 ± 3.8 ms(P = 0.007). The latency in the L group at the time point when the Bromage scale was 0 was 130.3 ± 10.2 ms, and in the LC group it was 144.7 ± 8.3 ms(P < 0.001). The CSP of the L group after 6 h was 59.6 ± 9.8 ms, while in the LC group it was 44.5 ± 5.0 ms(P < 0.001). The latency in the L group after 6 h was 110.4 ± 10.6 ms, while in LC group it was 132.3 ± 9.7 ms(P < 0.001).CONCLUSION Intrathecal addition of clonidine to levobupivacaine for SAB in comparison with levobupivacaine alone resultsin a diminished inhibitory tonus and shortened CSP.
