The Potential Value of Paraspinal Nerve Block (PVB) in Percutaneous Nephrolithotomy (PCNL) Compared with General Anesthesia and Epidural Anesthesia.

Objective: To analyze the potential value of paraspinal nerve block (PVB) in percutaneous nephrolithotomy (PCNL) and to compare it with general anesthesia and epidural anesthesia. Methods: 120 patients undergoing PCNL surgery in Shanghai Jiao Tong University Affiliated Sixth People's Hospital from January 2021 to June 2022 were selected and divided into PVB anesthesia group, general anesthesia group, and epidural anesthesia group according to different anesthesia methods, with 40 cases in each group. The anesthesia index (anesthesia operation time, anesthetic effect time, anesthesia time), the vital signs (heart rate, mean arterial pressure), postoperative pain [visual analog scale (VAS)], stress response index (cortisol and noradrenaline), the incidence of adverse reactions (nausea and vomiting, lethargy, dizziness, skin itching, bradycardia) were compared among the three groups. Results: The operation time of the anesthesia in the PVB anesthesia group was 5.72±1.25, which was significantly lower than that in the the general (7.95±1.15) and epidural anesthesia groups(8.23±1.43), and the differences were statistically significant (P = .000). The time of onset of anesthesia in the PVB anesthesia group was 6.63±1.87, which was significantly lower than that in the the general (9.84±2.41) and epidural anesthesia groups(10.14±2.89), and the differences were statistically significant (P = .000).The heart rate during percutaneous puncture and intraoperative lithotripsy in the PVB anesthesia group was statistically lower than in the general and epidural anesthesia groups (P < .05). The mean arterial pressure 20 minutes after anesthesia and at the end of operation in the PVB anesthesia group was higher than that in the general anesthesia group, and the mean arterial pressure during percutaneous puncture and intraoperative lithotomy was lower than that in the general anesthesia group (P < .05). The VAS scores of the PVB anesthesia group at 2, 6, 12, 24, and 48 hours after the operation were lower than those of general and epidural anesthesia groups (P < .05). The incidence of adverse reactions was 5.00% (2/40) in the PVB anesthesia group and 35.00% (14/40) in the general anesthesia group, which was lower than that of 27.50% (11/40) in the epidural anesthesia group. (P < .05). Conclusion: The potential value of PVB in PCNL is high is better than that of general anesthesia and epidural anesthesia, anesthesia can shorten operation time and work time, extend the time of anesthesia to maintain, and be helpful to the intraoperative vital signs in patients with stable, mild postoperative pain and stress, low incidence of adverse reactions, efficacy and safety are good, can be introduced.

The Effect of Adolescent Idiopathic Scoliosis on Natural Delivery and Epidural Use in Pregnant Females: A Matched Cohort Study.

STUDY DESIGN: Retrospective matched cohort study. OBJECTIVE: The aim of this study was to determine whether females with idiopathic scoliosis (IS), both with and without spine fusion, experience different rates of cesarean section (CS) and epidural anesthesia (EA) than females without scoliosis. SUMMARY OF BACKGROUND DATA: IS is a common spine condition with a higher prevalence in females. It is unclear whether females with scoliosis, treated nonoperatively or operatively, have different rates of cesarean delivery or EA. MATERIALS AND METHODS: Patients with IS who delivered in our integrated health care system during a 6-year period were identified (N = 1810). They were matched with a group without scoliosis who delivered during the same period (N = 1810). Rates and relative risk (RR) of CS and EA between cohorts and subgroups were calculated. RESULTS: The scoliosis cohort had significantly higher rates and RR of EA ( P = 0.002 and P = 0.004, respectively). Scoliosis patients treated nonoperatively had an 8% greater RR of EA ( P = 0.004) and had a significantly lower rate of CS (23.2% vs . 26%, P = 0.048) compared with the control group. Among only scoliosis patients, those treated with spine fusion had a 38% decreased RR of EA ( P < 0.001). Distal fusion level did not seem to influence the RR of EA or CS. CONCLUSIONS: Females with scoliosis were significantly more likely to receive EA at delivery compared with females without scoliosis. Rates and RR of cesarean delivery were not significantly lower among women with scoliosis, but females treated nonoperatively for scoliosis had a significantly lower CS rate than those without scoliosis. Females treated with spine fusion for scoliosis were far less likely to receive EA than both females without scoliosis and females with scoliosis treated nonoperatively.

Comparing the Effectiveness and Safety Between Local Anesthesia versus Epidural Anesthesia for Percutaneous Transforaminal Endoscopic Discectomy: A Systematic Review and Meta-Analysis.

OBJECTIVE: The objective of this study was to compare the effectiveness and safety of local anesthesia (LA) and epidural anesthesia (EA) for percutaneous transforaminal endoscopic discectomy (PTED) and provide reference data for clinical decision-making. METHODS: We searched PubMed, EMBASE, the Cochrane library, Web of Science, Medline, Science Direct, and China National Knowledge Infrastructure from inception to March 2022 to identify randomized and nonrandomized controlled trials comparing LA and EA for PTED. Studies that assessed at least 2 of the following indicators were considered eligible: surgical duration, X-ray exposure time, satisfaction rate, visual analog scale scores for pain, Oswestry Disability Index, and complications. Meta-analysis was conducted using Review Manager 5.3.3 software. RESULTS: Five randomized controlled trials and 5 retrospective cohort studies involving a total of 1660 patients were included. The LA and EA groups included 803 and 857 patients, respectively. Meta-analysis revealed significant intergroup differences in the intraoperative lumbar visual analog scale scores (P < 0.00001) and anesthesia satisfaction rate (P < 0.00001). There were no significant intergroup differences in the surgical duration, X-ray exposure time, postoperative Oswestry Disability Index, and complication rate. CONCLUSIONS: EA is as safe as LA and produces better anesthetic effects than LA in patients undergoing PTED. Therefore, EA should be promoted as a reliable anesthetic technique for PTED.

Efficacy and safety of epidural anesthesia versus local anesthesia in percutaneous transforaminal endoscopic discectomy: a systematic review and meta-analysis.

BACKGROUND: For some patients, local anesthesia (LA) in percutaneous transforaminal endoscopic discectomy (PTED), especially during canal shaping and discectomy, is insufficient for analgesia. Epidural anesthesia (EA) is infrequently applied in PTED but reports satisfactory results. Previous studies present conflicting results in analgesia satisfactory and adverse events. Differences in surgery details and small sample size might explain conflicting results. Meta-analysis pools the results from individual studies to create a larger sample size and provides a more reliable conclusion. The aim of this study is to evaluate the efficacy and safety of EA in PTED. METHODS: The search terms "percutaneous transforaminal endoscopic discectomy" and "anesthesia" are used to search Cochrane, Web of Science, PubMed, Embase, OVID, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang from inception to 2021-08. Inclusion criteria is defined according to PICOS principals: P (patients): patients are diagnosed with lumbar disc herniation or spinal canal stenosis. I (intervention): patients undergo PTED under EA. C (comparisons): patients undergo PTED under LA. O (outcomes): primary outcomes: intraoperative visual analogue scale (VAS), anesthesia satisfactory, sufentanil usage. Secondary outcomes: adverse events, surgery exit, bleed volume, X-ray radiation. S (study design): randomized controlled trials (RCTs). The Cochrane RoB 2.0 is used to evaluate the quality of the included studies. Authors perform meta-analysis through Review Manager 5.4. RESULTS: A total of 6 studies representing 529 patients are included: EA group includes 261 patients, and LA group includes 268 patients. All studies lack design of allocation concealment and blinding of participants and personnel. Only Luo reports blinding of outcome assessment in 2019. Meta analysis concludes that EA is superior in intraoperative analgesic [mean difference (MD) =-4.31; 95% confidence interval (CI): -4.52 to -4.09; P<0.00001], anesthesia satisfactory [odds ratio (OR) =10.06; 95% CI: 2.41 to 41.98; P=0.002], sufentanil usage (MD =-9.12; 95% CI: -10.34 to -7.90; P<0.00001), adverse events (OR =0.19; 95% CI: 0.07 to 0.52; P=0.001). There is no difference in bleed volume (MD =-2.61; 95% CI: -5.45 to 0.23; P=0.07), exit rate (OR =0.23; 95% CI: 0.04 to 1.35; P=0.10) and future effects (MD =-0.23; 95% CI: -0.50 to 0.03; P=0.08). DISCUSSION: EA is an effective and safe anesthesia method for PTED and might achieve better clinical results than LA. More high-quality research is needed to provide high-quality evidence for efficacy and safety.

Analgesic Effects of Dexmedetomidine Combined with Spinal and Epidural Anesthesia Nursing on Prostate Hyperplasia Patients after Transurethral Resection of Prostate by Intelligent Algorithm-Based Magnetic Resonance Imaging.

To analyze the investigation of the application effects of different doses of dexmedetomidine (Dex) with combined spinal and epidural anesthesia nursing on analgesia after transurethral resection of prostate (TURP) by intelligent algorithm-based magnetic resonance imaging (MRI), MRI imaging segmentation model of mask regions with convolutional neural network (Mask R-CNN) features was proposed in the research. Besides, the segmentation effects of Mask R-CNN, U-net, and V-net algorithms were compared and analyzed. Meanwhile, a total of 184 patients receiving TURP were selected as the research objects, and they were divided into A, B, C, and D groups based on random number table method, each group including 46 cases. Patients in each group were offered different doses of Dex, and visual analogue scale (VAS) and Ramsay scores of different follow-up visit time, use of other analgesics, the incidence of postoperative cystospasm, and nursing satisfaction of patients in four groups were compared. The results demonstrated that Dice similarity coefficient (DSC) value, specificity, and positive predictive value of Mask R-CNN algorithm were 0.623 ± 0.084, 98.61%, and 69.57%, respectively, all of which were higher than those of U-net and V-net algorithms. Pain VAS scores and the incidence of cystospasm at different time periods of groups B and C were both significantly lower than those of group D (P < 0.05). Ramsay scores of groups B and C at 8 hours, 12 hours, 24 hours, and 48 hours after the operation were all remarkably higher than those in group D (P < 0.05). Besides, nursing satisfaction of groups B and C was obviously superior to that in group D, and the difference demonstrated statistical meaning (P < 0.05). The differences revealed that Dex showed excellent analgesic and sedative effects and could effectively reduce the incidence of complications after TURP, including cystospasm and nausea. In addition, it helped improve nursing satisfaction and patient prognosis.

Combined spinal-epidural anesthesia with acupoint injection for labor anesthesia reduces IL-1ß/IL-10 ratio in maternal peripheral blood, umbilical cord blood and improves the labor outcomes: A prospective randomized controlled trial.

BACKGROUND: This study aimed to investigate the effects of combined spinal-epidural anesthesia (CSEA) with acupoint injection (AI) on the maternal-fetal expression of interleukin-1ß (IL-1ß), interleukin-10 (IL-10), analgesia effect, and labor outcomes. METHODS: A total of 360 healthy primiparas were randomized into the CSEA+AI group, the CSEA group, the AI group, and the control group (n = 90, each group) according to the labor analgesia methods. RESULTS: Compared to the CSEA group, the CSEA+AI group had significantly lower visual analog scale (VAS) scores, adverse events, dose of ropivacaine/sufentanil, and shorter labor durations. The IL-1ß/IL-10 ratio in maternal peripheral blood and umbilical cord blood was reduced in the CSEA+AI group compared with the CSEA group. CONCLUSION: The combination of CSEA and AI can reduce the ratio of IL-1ß/ IL-10 in maternal peripheral blood and umbilical cord blood, which can effectively relieve labor pain.

Local anesthesia, epidural anesthesia and general anesthesia comparison in lumbar disc herniation: a network meta-analysis.

There were 3 major anesthesia methods for discectomy: local, epidural and general. A lot of studies has been established to compare these three methods in different aspects, however, the result is still controversial. We conducted this network meta-analysis to evaluate these methods. Electronic databases including PubMed, EMBASE, Cochrane Library, were searched to identify clinical trials that reported the effects of local anesthesia general anesthesia and epidural anesthesia in lumbar disc herniation. Three indicators were included for evaluation: post-operative VAS score, complication, operation duration. In total, 12 studies and 2287 patients were included for this study. For complication, epidural anesthesia shows significantly lower rate compare to general anesthesia (OR: 0.45, 95% CI [0.24, 0.45], P=0.015), but local anesthesia didn't show significant result, no significant heterogeneity was observed between designs. For VAS score, epidural anesthesia showed a better effect (MD: -1.61, 95%CI [-2.24, -0.98]) compare to general anesthesia, and local anesthesia has a similar effect (MD: -0.91, 95%CI [-1.54, -0.27]). However this result showed a very high heterogeneity (I2=95%). For operation duration, local anesthesia showed a significant lesser time compare to general anesthesia (MD: -46.31(minutes), 95%CI [-73.73, -19.19]) but epidural anesthesia didn't have one, this result also showed a very high heterogeneity (I2=98%). Epidural anesthesia showed lesser post- operative complication compare to general anesthesia in lumbar disc herniation surgery.

Effect Analysis of Epidural Anesthesia with 0.4% Ropivacaine in Transforaminal Endoscopic Surgery.

Background: Epidural anesthesia used in percutaneous endoscopic lumber discectomy (PELD) has the risk of complete neurotactile block. Patients cannot timely respond to the operator when the nerve is touched by mistake, so the potential risk of nerve injury cannot be avoided. According to pharmacodynamics, with the decrease of local anesthetic concentration, the nerve tactile gradually recovered; however, the analgesic effect also gradually weakened. Therefore, it is necessary to explore an appropriate concentration of local anesthetics that can keep the patients' nerve touch without pain. By comparing the advantages and disadvantages of 0.4% ropivacaine epidural anesthesia, local anesthesia and intravenous anesthesia on intraoperative circulation fluctuation, the incidence of salvage analgesia and the incidence of nerve non-touch, the feasibility of using low concentration epidural anesthesia in PELD to obtain enough analgesia and avoid the risk of nerve injury was confirmed. Methods: 153 cases of intervertebral foramen surgery from October 2017 to January 2020 were selected and divided into local anesthesia group (LA group), 0.4% ropivacaine epidural anesthesia group (EA group), and intravenous anesthesia group (IVA group) according to different anesthesia methods. The changes of blood pressure and heart rate, the incidence of rescue analgesia and nerve root non-touch were compared among the three groups. Results: The difference of map peak value among the three groups was statistically significant (P < 0.001); pairwise comparison showed that the map peak value of the LA group was higher than that of the EA group (P < 0.001) and IVA group (P < 0.001), but there was no statistical significance between the EA group and IVA group. The difference of HR peak value among the three groups was statistically significant; pairwise comparison showed that the HR peak value of the LA group was higher than that of the EA group (P < 0.001) and IVA group (P < 0.001), but there was no statistical significance between the EA group and IVA group. There was significant difference in the incidence of intraoperative hypertension among the three groups (P < 0.05); pairwise comparison showed that the incidence of intraoperative hypertension in the EA group was lower than that in the LA group (P < 0.05), while there was no significant difference between the IVA group, EA group, and LA group. There was significant difference in the incidence of rescue analgesia among the three groups (P < 0.01); pairwise comparison showed that the incidence of rescue analgesia in the EA group was lower than that in the LA group (P < 0.05) and IVA group (P < 0.05), but there was no significant difference between the LA group and IVA group. Due to the different analgesic mechanisms of the three anesthesia methods, local anesthesia and intravenous anesthesia do not cause the loss of nerve tactile, while the incidence of nerve tactile in 0.4% ropivacaine epidural anesthesia is only 2.4%, which is still satisfactory. Conclusion: Epidural anesthesia with 0.4% ropivacaine is a better anesthesia method for PELD. It not only has a low incidence of non-tactile nerve, but also has perfect analgesia and more stable intraoperative circulation.

Neuraxial vs General Anesthesia: 30-Day Mortality Outcomes Following Transurethral Resection of Prostate.

OBJECTIVE: To examine the occurrence of 30-day mortality, and other procedure related morbidities in cohorts of patient receiving neuraxial anesthesia (NAX) or general anesthesia (GA) in the setting of transurethral resection of the prostate (TURP). Historically, NAX has been recommended for patients undergoing TURP permitting monitoring of consciousness and early diagnosis of absorption-related hyponatremia. We aim to analyze a broader comparison of mortality and other associated morbidities regarding the form of anesthesia utilized. METHODS: The National Surgical Quality Improvement Program (NSQIP) database was accessed and queried from January 2010 to December 2016 for TURP. 28,486 TURP cases were identified and further stratified by the type anesthesia administration, NAX 7,261 and GA 21,225. Chi-square analyses and Kaplan-Meier tests were performed for univariate comparisons. Using propensity score, data were optimally (1:1) matched to account for potential confounding variables. Outcomes were then compared for NAX vs. GA with a primary endpoint of 30-day mortality, followed by secondary endpoint of adverse outcomes reported per NSQIP. RESULTS: Prior to matching, 30-day mortality was found to be 0.4% in the NAX cohort and 0.7% GA. 12,180 patients equally matched between the 2 groups. NAX was found to be superior to GA in terms of 30-day survival benefit (OR 0.55, 95% CI 0.33 -0.92, P <0.05), sepsis (OR 0.60, 95% CI 0.50 -0.73, P <0.001), and return to operating room (OR 0.76, 95% CI 0.60 -0.98, P <0.05) when comparing matched cohorts. NAX was associated with lower incidence of overall adverse clinical outcomes 12.4% vs 13.7% (P = 0.036). CONCLUSION: NAX was found to have statistically relevant advantage for 30-day postoperative outcomes when compared to GA for TURP based on NSQIP database reporting.

Effects of General Anesthesia Combined with Epidural Anesthesia on Cognitive Dysfunction and Inflammatory Markers of Patients after Surgery for Esophageal Cancer: A Randomised Controlled Trial.

OBJECTIVE: To evaluate the impact of general anesthesia (GA) combined with epidural anesthesia (GAEA) on postoperative cognitive dysfunction (POCD) and inflammatory markers in patients with esophageal cancer (EC).   Study Design: A randomised controlled trial. PLACE AND DURATION OF STUDY: Department of Anesthesiology, Traditional Chinese Medicine Hospital of Southwest Medical University, Luzhou, Sichuan Province, China, from August 2019 to April 2020. METHODOLOGY: SPSS was used to randomly divide 142 cases into two groups, namely: the GA (n=71) and GAEA (n=71) categories. 128 candidates were used in this study. Cognitive function and the levels of interleukin 6 (IL-6), interleukin 8 (IL-8), and tumor necrosis markers α (TNF-α) in serum were evaluated at baseline, 1, 3 and 7 days after operation by Montreal Cognitive Assessment (MoCA) and enzyme-linked immunosorbent assay (ELISA), respectively. Pearson correlation analysis was used to assess the interrelationships between MoCA score and inflammatory markers levels. RESULTS: Compared to the GA group (n=64), the GAEA category (n=64) showed significantly higher MoCA score on 1 day and 3 days postoperatively (all p <0.05). IL-6, IL-8 and TNF-α in the GA group were significantly increased on 1, 3 and 7 days after surgery (all p <0.05). Pearson correlation analysis indicated that the three inflammatory markers were inversely correlated with cognitive function score (all p <0.05). The postoperative adverse events between the two groups were comparable (all p >0.05). CONCLUSION: Combining general and epidural anesthesia may reduce the incidence of POCD in patients undergoing esophagectomy by suppressing inflammatory response. Key Words: General anesthesia, Epidural anesthesia, Esophageal cancer, Postoperative cognitive dysfunction, Inflammatory markers.

Safety and acceptance of "Vibwife", a new moving mattress to support mobilization during labor: Result of a clinical study.

OBJECTIVE: To examine the safety and acceptance "Vibwife", a new moving mattress to support mobilization of pregnant women during labor. DESIGN: The study was a prospective medical device clinical study without a control group. The study was designed in intervention phases, with safety evaluation by a safety review board after each intervention phase. SETTING: The study took place at the University Hospital of Basel, Switzerland. PARTICIPANTS: 50 women were included with a low risk singleton pregnancy > 37th weeks during the first stage of labor. INTERVENTION: Evaluation of the safety and acceptance of women, midwives and physicians during the first stage of labor. The intervention was carried out in 3 phases. In the first phase five women in labor used the device for 10 minutes, the next 10 women for 20 minutes, and finally the next 35 women for 30 minutes. MEASUREMENTS: Measurement included capturing Adverse Events (AEs) (including Adverse Device Effects (ADEs)), Serious Adverse Events (SAEs) and recording vital parameters before, during, and after intervention, as well as CTG before and after intervention. Acceptance by women, midwives and physicians was measured by questionnaires with a 4-point Likert scale and pain intensity by a discrete Visual Analogue Scale (VAS) from 0-10. FINDINGS: No SAE occurred during the trial. A total of 32 AEs occurred in 25 women during the intervention or in the 30 minutes follow-up. The most frequently observed AEs were modification of blood pressure and CTG abnormalities. None of the 32 AEs led to sequels of any kind. The relationship between AEs occurrence and the use of the medical device was viewed as certain in 2 cases (6.2%), possible or likely in 8 cases (25%), and unlikely or unrelated in 22 cases (68, 7%). Overall, women, midwives and physicians reported high satisfaction with their use of the device. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: The medical device "Vibwife" was judged as safe for women. Acceptance among women and health personnel was good. Considering the potential benefits of mobilization during labor, this new medical device could be a very interesting adjunct to other obstetrical tools. Particularly, women whose mobility is restrained by epidural anesthesia while giving birth could be very suitable candidates. To answer the question of efficacy, a randomized-controlled trial is required.

Why is the labor epidural rate low and cesarean delivery rate high? A survey of Chinese perinatal care providers.

OBJECTIVE: China has a high cesarean delivery (CD) and low labor epidural analgesia (LEA) rate. This online survey was conducted to explore the reasons behind this phenomenon and potential solutions. METHODS: A voluntary, anonymous survey was distributed via both WeChat and professional websites for 4 months amongst groups of Chinese perinatal professionals. Data was collected and analyzed using a Chi-square test and presented as percentages of respondents. RESULTS: 1412 respondents were recorded (43% anesthesiologists, 35% obstetricians, 15.5% midwives or labor and delivery nurses, and 6.5% others), and 1320 respondents were care providers. It was found that 82.7% (1092/1320) of the provider respondents used CD per patient request in fear of lawsuits or yinao/yibao and 63.4% (837/1320) used CD for respecting superstitious culture. The number one reason (noted by 60.2% (795/1320) of all the three specialties) for low LEA use was lack of anesthesia manpower without statistical difference among specialties. The most recommended solution was increasing the anesthesia workforce, proposed by 79.8% (1053/1320) of the three specialties. However, the top solution provided by the two non-anesthesia specialties is different from the one proposed by anesthesiologists. The later (83%, 504/606) suggested increasing the incentive to provide the service is more effective. The answers to questions related to medical knowledge about CD and LEA, and unwillingness of anesthesiologists, parturients and their family members to LEA were similar for the most part, while the opinions regarding low LEA use related to poor experiences and unwillingness of obstetricians and hospital administrators were significantly divided among the three specialties. In the providers' point of view, the unwillingness to LEA from parturient's family members was the most salient (26.1%, 345/1320), which is more than all care providers, hospital administrators, and parturients themselves (16.8%, 222/1320). CONCLUSION: The reasons for high CD rate and low LEA use are multifactorial. The sociological issues (fear of yinao/yibao and superstitious culture) were the top two contributing factors for the high CD rate in China, while lack of anesthesia manpower was the top response for the low LEA use, which contributes to its being the most recommended solution overall from the three specialties. An incentive approach to providers is a short-term solution while training more perinatal care providers (especially among anesthesiologists and midwives), improving billing systems, and reforming legal systems are 3 systemic approaches to tackling this problem in the long-term.

Rectal Prolapse Repair with Abdominal Fixation Under Sedation and Local or Epidural Anesthesia: Prospective Pilot Study in 10 Elderly Subjects.

Background: Rectal prolapse (RP) is primarily a disease of the elderly, where treatment may be associated with significant postoperative morbidity including that related to anesthesia. Objective: The aim of this study was to evaluate the safety and feasibility of a novel abdominal approach to RP repair under sedation and local anesthesia and to assess short- and long-term clinical outcomes in elderly patients (>70 years). Design Settings: This is a prospective pilot study with 10 patients using a novel RP repair. The anesthesia type was local or epidural with sedation. Follow-up was done at 30 days, 12, and 24 months. Patients: Patients were men and women >70 years of age with RP. Main Outcome Measures: (1) Feasibility: successful completion of RP repair using the novel abdominal approach with laparoscopic assistance. (2) Safety: safety was measured by the incidence of the intraoperative complications (bowel perforation, organ injury, and bleeding requiring blood transfusion). (3) Sedation and local anesthesia feasibility: surgery was safely completed without patient intubation. Results: Ten female patients >70 years of age underwent RP repair using the novel abdominal approach. General anesthesia was not required in any of the 10 patients. Two patients recurred within 6 months. One of the patients with recurrence of RP subsequently underwent laparoscopic rectopexy, and the other was minimal and required no further treatment. One mortality occurred at 3 months unrelated to the procedure. No other anesthetic or surgical intraoperative and postoperative complications were observed. Limitations: This is a single-institution pilot study. Conclusions: Abdominal RP repair under sedation and regional anesthesia appears feasible and safe in elderly patients and may, in the future, provide an effective alternative to current treatment options for RP, avoiding general anesthesia.

Epidurals during normal labour and birth - Midwives' attitudes and experiences.

BACKGROUND: Midwives have their own beliefs and values regarding pain during childbirth. Their preferences concerning labour pain management may influence women's choices. AIM: To gain a deeper understanding of midwives' attitudes and experiences regarding the use of an epidural during normal labour. METHODS: A qualitative approach was chosen for data collection. Ten in-depth interviews were conducted with midwives working in three different obstetric units in Norway. The transcribed interviews were analysed using Malterud's systematic text condensation. FINDINGS: The analysis provided two main themes: "Normal childbirth as the goal" and "Challenges to the practice, knowledge, philosophy and experience of midwives". Distinctive differences in experiences and attitudes were found. The workplace culture in the obstetric units affected the midwives' attitudes and their midwifery practice. How they attended to women with epidural also differed. An epidural was often used as a substitute for continuous support when the obstetric unit was busy. DISCUSSION: Midwives estimate labour pain differently, and this might impact the midwifery care. However, midwives' interests and preferences concerning labour pain management should not influence women's choices. Midwives are affected by the setting where they work, and research highlights that an epidural might lead to a focus on medical procedures instead of the normality of labour. CONCLUSION: Midwives should be aware of how powerful their position is and how the workplace culture might influence their attitudes. The focus should be on "working with" women to promote a normal birth process, even with an epidural.

Comparison of surgical outcomes of lumbar disc herniation using local anesthesia and epidural anesthesia: A meta-analysis.

We performed this meta-analysis to evaluate the effects of epidural anesthesia and local anesthesia on the surgical outcomes of lumbar disc herniation (DH).Electronic databases including PubMed, EMBASE, Cochrane Library, and the Chinese Academic Journal Full-text Database were searched to identify randomized controlled trials (RCTs) that reported on the effects of local anesthesia and epidural anesthesia in lumbar DH surgical management. Evaluation indicators included: onset time of anesthesia, patient satisfaction, and the rate of adverse effects. There were 6 RCTs with a total of 606 patients in this meta-analysis: 274 cases in the local anesthesia group and 332 in the epidural anesthesia group.This meta-analysis demonstrated that the epidural anesthesia group had a better analgesic effect, a lower adverse effect rate (mean difference [MD] = 0.21, 95% confidence interval [CI] [0.08, 0.54], P = .001) and a better satisfaction rate: (MD = 6.54, 95% CI [2.77, 15.45], P < .0001). The duration of anesthesia was not statistically significant.Epidural anesthesia is a better choice for lumbar DH surgery compared to local anesthesia.

Awake laparotomy: is locoregional anesthesia a functional option for major abdominal surgeries in the COVID-19 era?

OBJECTIVE: Over the ongoing pandemic of coronavirus disease 2019 (COVID-19), the demand for critical care beds among medical services has rapidly exceeded its supply. Elective surgery has comprehensively been drastically limited and allocating intensive care beds to emergency cases or to high risk scheduled elective cases has become an even more difficult task. Here we present our experience which could help to handle undelayable surgical procedures during this emergency. PATIENTS AND METHODS: In 2019, eight patients (4 men, 4 women) with a mean age of 88 years, needing emergency abdominal surgery underwent awake open surgery at our Department of Surgery. All of them were identified as fragile patients at preoperative evaluation by the anesthesiologist. In all cases, locoregional anesthesia (spinal, epidural or combined spinal-epidural anesthesia) was performed. Intraoperative and postoperative pain has been monitored and regularly assessed. RESULTS: None of the patients was intubated. Mean operative time was 80 minutes (minimum 30 minutes, maximum 130 minutes). Intraoperative and postoperative pain were both well controlled. None of them required postoperative intensive care support. No perioperative complications were observed. CONCLUSIONS: Based on our preliminary case series, awake open surgery has resulted feasible and safe. This approach has allowed to perform undelayable major abdominal surgeries on fragile patients when intensive care beds were not available. Surely, it represents a helpful alternative in the COVID-19 era. A streamlining of workflows would fast-track both fragile patients management, as well as healthcare workers' tasks and activity.

Preoperative hypnosis for pain management after arthroscopic repair of anterior cruciate ligament.

BACKGROUND: The practice of hypnoanalgesia in orthopedics is rare and the literature is poor. AIM: The purpose of this pilot study was to verify the efficacy of hypnosis for the management of postoperative analgesia after arthroscopic repair of anterior cruciate ligament. METHODS: This was a prospective clinical trial over a period of 6 months (March - August 2015) including 25 patients scheduled for arthroscopic repair of anterior cruciate ligament under spinal anesthesia. All these patients had preoperative hypnosis in addition to the standard multimodal analgesia protocol (group H) and were compared to historical group (group S) who received only a standard multimodal analgesia protocol. RESULTS: Pain scores were significantly lower for the hypnosis group during the first 48 hours postoperatively (p = 0,006). The total dose of morphine at 48 hours was: 13,6 mg (95% CI [4,58; 22,62]) in the group H and 10,2 mg (95% CI [1,64 ; 18,76]) in group S with no statistically significant difference (p = 0,178) Conclusion: Results of this pilot study in orthopedic surgery suggested that hypnosis reduced postoperative pain scores as demonstrated in other surgeries.

Thoracoscopic lung biopsy under regional anesthesia for interstitial lung disease.

BACKGROUND: Interstitial lung disease (ILD) management guidelines support lung biopsy-guided therapy. However, the high mortality associated with thoracoscopic lung biopsy using general anesthesia (GA) in patients with ILD has deterred physicians from offering this procedure and adopt a diagnostic approach based on high-resolution CT. Here we report that thoracoscopy under regional anesthesia could be a safer alternative for lung biopsy and effectively guide ILD treatment. METHODS: This was a single-center retrospective review of prospectively maintained database and consisted of patients who underwent thoracoscopic lung biopsy between March 2016 and March 2018. Patients were divided into two groups: (A) GA, and (B) regional anesthesia using monitored anesthesia care (MAC) and thoracic epidural anesthesia (TEA). RESULTS: During the study period, 44 patients underwent thoracoscopic lung biopsy. Of these, 15 underwent MAC/TEA. There were no significant differences between the two groups with regard to pulmonary function test and clinicodemographic profile. However, operative time and hospital stay were shorter in MAC/TEA group (32.5±18.5 min vs 50.8±18.4; p=0.004, 1.0±1.3 days vs 10.0±34.7 days; p<0.001, respectively). Eight patients in the GA group, but none in the MAC/TEA group, experienced worsening of ILD after lung biopsy (p=0.03). Additionally, one patient in the GA group died due to acute ILD worsening. No cases of MAC/TEA group had to be converted to GA. In all cases a pathological diagnosis could be made. CONCLUSIONS: Thoracoscopy using regional anesthesia might be a safer alternative to lung biopsy in patients with ILD.

Comparison of effectiveness and safety between epidural anesthesia vs local anesthesia for percutaneous transforaminal endoscopic discectomy: A systematic review and meta-analysis.

OBJECTIVES: To compare the effectiveness and safety of epidural anesthesia (EA) with those of local anesthesia (LA) for percutaneous transforaminal endoscopic discectomy (PTED) and provide reference data for clinical decision-making. METHODS: We searched PubMed, Embase, the Cochrane library, Web of Science, Medline, ScienceDirect, and the China National Knowledge Infrastructure from inception to June 2019 in order to identify randomized and nonrandomized controlled trials comparing EA and LA for PTED. Studies assessing at least 2 of the following indicators were eligible: surgical duration, X-ray exposure time, satisfaction rate, visual analog scale (VAS) scores for pain, Oswestry Disability Index (ODI), and complications. Two assessors evaluated the quality of the literature using the Cochrane Handbook or Newcastle-Ottawa Scale. Meta-analysis was conducted using Review Manager 5.3.3 software. RESULTS: Four randomized controlled trials and 4 retrospective cohort studies involving a total of 1000 patients were included. The LA and EA groups included 473 and 527 patients, respectively. Meta-analysis revealed significant intergroup differences in the intraoperative (P < .00001) and postoperative (P < .00001) lumbar VAS scores, intraoperative (P < .00001) and postoperative (P = .001) leg VAS scores, and anesthesia satisfaction rate (P < .00001), with EA being superior to LA in all aspects. There were no significant intergroup differences in the surgical duration, X-ray exposure time, postoperative ODI, and complication rate. CONCLUSION: EA is as safe as LA and produces better anesthetic effects than does LA in patients undergoing PTED. Therefore, it should be promoted as a reliable anesthetic technique for PTED.

Stepwise Local Anesthesia for Percutaneous Endoscopic Interlaminar Discectomy: Technique Strategy and Clinical Outcomes.

BACKGROUND: Due to suboptimal pain control under conventional local anesthesia, percutaneous endoscopic interlaminar discectomy is typically performed under general anesthesia. The purpose of this study was to develop a stepwise approach of local anesthesia for endoscopic interlaminar discectomy and evaluate its efficacy. METHODS: A stepwise local anesthesia was developed, which mainly includes 3 steps: conventional local anesthesia from skin to laminae, epidural injection, and nerve root block. From June 2015 to May 2017, consecutive patients who underwent endoscopic interlaminar discectomy were included. Local anesthesia or general anesthesia was used based on patients' preference. Anesthetic effectiveness was evaluated as excellent, good, or poor, and adverse events were recorded. Hospitalization expense was compared between the 2 groups. Clinical outcomes were assessed using the Visual Analog Scale and the Oswestry Disability Index. RESULTS: There were 98 patients included in the study. Among them, 48 received stepwise local anesthesia and the other 50 received general anesthesia. In the stepwise local anesthesia group, 40 (83.3%) patients rated anesthetic effectiveness as excellent, 7 (14.6%) as good, and 1 (2.1%) as poor. Nine patients had complications that may be associated with local anesthesia, including dyspnea, temporary paresis of legs, and temporary worsened dysesthesia or numbness in legs. After surgery, the patients' leg pain and Oswestry Disability Index significantly improved in both groups. On average, hospitalization expense was approximately 20% less when local anesthesia was used, as compared with using general anesthesia. CONCLUSIONS: The stepwise local anesthesia can achieve satisfactory pain control and seems to be a good choice for endoscopic interlaminar discectomy.
