RESUMEN
Context: Splanchnic nerve block (SPN) with local anesthetic and steroid is used to relieve the pain of chronic pancreatitis. However, it does not provide long-lasting relief. We hypothesize that the use of 70% alcohol will give adequate analgesia for more than months. Aims: The primary objective was to find out the analgesic efficacy of the use of 70% alcohol with SPN. Secondary objectives included the incidence of side effects, analgesic consumption postintervention, quality of life (QOL) assessed via a self-reported quality of life scale, and repeat block during the 1-year follow-up period. Settings and Design: Retrospective analysis of all patients with chronic pancreatitis who received bilateral SPN over the last 4 years. Methods and Materials: SPN was performed using the posterior retrocrural approach with the patient in the prone position as described in the literature using a 23 G × 90 mm spinal needle bilaterally at the level of T12 using C-arm/fluoroscopy guidance. Data were collected from the procedure book of the pain clinic and medical records. Statistical Analysis Used: Quantitative data for change in pre- to post-block VAS score was collected using the non-parametric Wilcoxon signed ranks test. Results: The baseline VAS, post-procedure VAS, and VAS at 3 months follow-up was 7.69 ± 1.3,2.44 ± 0.96 and 1.56 ± 1.15. A pairwise comparison of VAS performed between baseline and immediate post-procedure, baseline, and VAS at 3 months was found to be highly significant. Conclusions: Fluoroscopy-guided neurolytic SPN with 70% alcohol gives significant pain relief for more than 3 months. It also leads to improvement in 3 months QOL.
RESUMEN
Background and Aims: Postoperative pain can impede functional recovery and delay hospital discharge after functional endoscopic sinus surgery (FESS). The study aimed to assess the efficacy of ultrasound (USG)-guided suprazygomatic maxillary nerve block (SZMNB) for postoperative pain in FESS. Methods: Forty-eight adult patients between 18 and 65 years of age with American Society of Anesthesiologists physical status I and II and scheduled to undergo FESS were enroled in this randomised controlled study. Patients were randomly allocated to either receive USG-guided SZMNB with general anaesthesia (n = 24) or general anaesthesia alone (n = 24). The numerical rating scale (NRS) pain score in the immediate postoperative period was recorded as the primary outcome. A total of 24 h postoperative rescue analgesic consumption, surgeon satisfaction score, postoperative haemodynamics, and postoperative complications were noted as secondary outcomes. Results: The median (interquartile range) of the NRS pain score in the immediate postoperative period was 0 (0-0.25)[95% confidence interval (CI): 0, 0.08] in the block group compared to 2 (1.75-3) [95% CI: 1.60, 2.40] in the control group, P < 0.001]. Pain scores were significantly reduced at all time intervals till 24 h after surgery (P < 0.001). None of the patients required rescue analgesia in the block group. In contrast, eight patients required diclofenac 75 mg intravenous as rescue analgesia within 1 h of surgery and ten patients within 1-6 h of surgery in the control group. Other secondary outcomes were comparable between groups (P > 0.05). Conclusion: The USG-guided SZMNB provides excellent postoperative analgesia for patients undergoing FESS without significant side effects.
RESUMEN
The effects on the stress response, postanesthetic sedation, and altered behavior were evaluated following regional anesthesia and dental treatment in 40 dogs. Serum cortisol and blood glucose concentrations were measured following the administration of levobupivacaine (LBUP) 0.5% and dexmedetomidine (DEX) (0.5â µg/kg) or a placebo. The dogs were randomly assigned to 4 groups of 10 dogs each. All dogs received a regional nerve block using LBUP 0.5%. Group 1 (LBUP + DEX IV) also received DEX intravenously (IV); group 2 (LBUP + PLC IV) also received a placebo IV; group 3 (LBUP + DEX IO) also received DEX in one infraorbital (IO) block; and group 4 (LBUP + DEX IA) also received DEX in one inferior alveolar (IA) block. Serum cortisol and blood glucose concentrations were determined before the administration of oral blocks and at the end of the procedure. Sedation and behavior scores were assessed before premedication and hourly for 6â h after the end of anesthesia. Cortisol concentration did not change in any group at either evaluation time. The glucose concentration was higher (P < .05) only in the LBUP + DEX IA group at the end of the procedure. The sedation score was higher until the end of the observation period only in the LBUP + DEX IV and LBUP + PLC IV groups. No change in behavior score was observed in any of the groups. The reduction of perioperative stress response in all groups was due to the use of LBUP and not DEX.
RESUMEN
INTRODUCTION: Our study assesses the association between cryoablation, with and without nerve block supplementation, post-Nuss procedure pain, and opioid use in pectus excavatum (PE) patients. METHODS: We conducted a retrospective cohort study at a single center for PE patients who underwent the Nuss procedure from 2017 to 2022. Outcomes included postoperative opioid use (measured in oral morphine milligram equivalent per kilogram [OME/kg]), average pain score (scale 0-10), and length of stay (LOS). RESULTS: One hundred sixty-four patients (146 males and 18 females) were included, with 79 (48.2%) receiving neither cryoablation nor nerve block, 60 (36.6%) receiving intraoperative cryoablation alone, and 25 (15.2%) receiving both cryoablation and nerve block. The median age was 16 y. Nerve block recipients consumed fewer opioids during hospitalization than cryoablation alone and nonintervention groups (1.5 versus 2.3 versus 5.8 OME/kg, respectively, P < 0.0001). Average pain scores over the total LOS were lower in nerve block recipients (3.5 versus 3.8 versus 4.2, P = 0.03), particularly on postoperative day 0 (P = 0.002). Nerve block recipients had a shorter LOS than cryoablation alone and nonintervention groups (43.4 versus 54.7 versus 66.2 h, P < 0.0001). On multivariate analysis, cryoablation alone resulted in significantly less opioid use compared to no intervention (3.32 OME/kg reduction, 95% confidence interval -4.16 to -2.47, P < 0.0001). Addition of nerve block further reduced opioid use by 1.10 OME/kg (95% confidence interval -2.07 to -0.14, P = 0.04). CONCLUSIONS: Cryoablation with nerve block supplementation is associated with reduced pain, opioid use, and LOS post-Nuss for PE repair compared to cases without cryoablation or with cryoablation only. Cryoablation with regional nerve blocks should be considered for Nuss repair under the enhanced recovery after surgery pathway.
RESUMEN
We describe the case of a 28-year-old man with Brugada syndrome who received single-shot adductor canal and sciatic nerve blocks for the management of post-operative pain related to extensive orthopedic injuries. Low-dose ropivacaine with glucocorticoid additives was administered without any EKG changes, arrhythmias, or syncopal sensations. The patient experienced pain relief for over 24 h and was monitored on telemetry with defibrillator pads as a cardiac precaution. This case adds a valuable data point in the limited canon of information on the safety and efficacy of regional anesthesia in Brugada syndrome for the perioperative physician.
RESUMEN
Pain is a common reason that patients seek care in the emergency department (ED). Regional anaesthesia in the form of nerve blocks provides an excellent alternative to traditional forms of analgesia, and may be superior in managing musculoskeletal pain compared to opioids. Adequate pain management improves patient satisfaction, facilitates examination and minor procedures, and allows for earlier and safe discharge. In low resource settings this modality is underutilised due to lack of trained providers and/or support from specialised services, shortages of equipment, and lack of context-sensitive guidelines. Advances in ultrasound guided regional anaesthesia has the potential to improve access to safe and reliable anaesthesia. It is often not accessible or an active part of training even for emergency physicians. There are, however, a number of nerve blocks that are easy to learn, don't require specialised equipment, and can be readily applied in EDs for minor procedures and longer acting forms of analgesia. Nerve blocks more applicable in the operating theatre or best done under ultrasound guidance are mentioned but not discussed in this article. This continuous professional development (CPD) article aims to provide guidance with respect to several key areas related to more commonly used types of regional anaesthesia in district level services. We discuss the importance of good clinical practice including thorough preparation of equipment and the patient to avoid common complications, clinical indications for regional blocks in the ED, local anaesthetic agents, different techniques for some common regional blocks, potential complications, and the need for a trained interprofessional team.

Spinal and epidural blocks are commonly employed for pain relief during and following cesarean section. Intrathecal morphine (ITM) has been the gold standard for the same for many years. In recent times, many peripheral nerve blocks (PNBs) have been tried for postoperative analgesia following cesarean delivery (PACD). This article has reviewed the common PNBs used for PACD. The role of PNBs along with ITM has been studied and the current best strategy for PACD has also been explored. Currently, Ilio-inguinal nerve and anterior transversus abdominis plane block in conjunction with intrathecal morphine have been found to be the most effective strategy, providing lower rest pain at 6 hours as compared to ITM alone. In patients not receiving intrathecal morphine, recommended PNBs are lateral transversus abdominis plane block, single shot local anesthetic wound infiltration, or continuous wound infiltration with catheter below rectus fascia. PNBs are recommended for PACD. They have an opioid-sparing effect and are devoid of adverse effects associated with central neuraxial blocks such as hypotension, bradycardia, and urine retention. However, caution must be observed with PNBs for possible local anesthetic toxicity due to the large volumes of drug required.
RESUMEN
Background and Aims: Moderate-to-severe intensity pain is reported on the first day following lower abdominal surgery. No study has compared transversus abdominis plane (TAP) block with retrolaminar block (RLB) in laparoscopic inguinal hernia surgery for postoperative pain relief. Material and Methods: In this prospective, randomized trial, 42 male patients of American Society of Anesthesiologists (ASA) physical status I and II, aged 18-65 years, and having a BMI <40 kg/m2 received TAP or RLB following laparoscopic inguinal hernia surgery. A standard general anesthetic technique was performed. Patients were randomized into two groups: single-shot TAP block (group I) (n = 21) or the RLB (group II) (n = 21) with bilateral 20 ml of 0.375% ropivacaine. Postoperatively, IV paracetamol 1 g was administered as rescue analgesia. Postoperative cumulative Visual Analogue Scale (VAS) score 24 hours after surgery was considered as the primary outcome. Results: Postoperative cumulative VAS score at rest at 24 h, represented as mean ± S.D (95% CI), in the TAP block group was 3.54 ± 3.04 (2.16-4.93) and in the RLB group was 6.09 ± 4.83 (3.89-8.29). P value was 0.112 and VAS on movement was 7.95 ± 3.41 (6.39-9.50 [2.5-15.0]) in TAP block group, whereas P value was 0.110 and VAS on movement was 10.83 ± 5.51 (8.32-13.34) in the RLB group. Conclusion: Similar postoperative cumulative pain score on movement at 24 h was present in patients receiving TAP block or RLB. However, VAS score at rest and on movement was reduced in patients receiving TAP block at 18 and 24 h postoperatively.
RESUMEN
BACKGROUND: Continuous peripheral nerve blocks are widely used for anesthesia and postoperative analgesia in lower limb surgeries. The authors aimed to develop a novel continuous sacral plexus block procedure for analgesia during total knee arthroplasty. METHODS: The study comprised two stages. In Stage I, the authors built upon previous theories and technological innovations to develop a novel continuous sacral plexus block method, ultrasound-guided continuous parasacral ischial plane block (UGCPIPB) and subsequently conducted a proof-of-concept study to assess its effectiveness and feasibility. Stage II involved a historical control study to compare clinical outcomes between patients undergoing this new procedure and those receiving the conventional procedure. RESULTS: The study observed a 90% success rate in catheter placement. On postoperative day (POD) 1, POD2, and POD3, the median visual analog scale (VAS) scores were 3 (range, 1.5-3.5), 2.5 (1.6-3.2), and 2.7 (1.3-3.4), respectively. Furthermore, 96.3% of the catheters remained in place until POD3, as confirmed by ultrasound. The study revealed a significant increase in skin temperature and peak systolic velocity of the anterior tibial artery on the blocked side compared with those on the non-blocked side. Complications included catheter clogging in one patient and leakage at the insertion site in two patients. In Stage II, the novel technique was found to be more successful than conventional techniques, with a lower catheter displacement rate than the conventional procedure for continuous sciatic nerve block. CONCLUSION: UGCPIPB proved to be an effective procedure and safe for analgesia in total knee arthroplasty. CHINESE CLINICAL TRIAL REGISTRY NUMBER: ChiCTR2300068902.

Upper extremity injuries are frequent in athletes which may require surgeries. Regional anesthesia for postoperative analgesia is important to aid recovery, and peripheral nerve blocks for surgical anesthesia enable surgeries to be performed without general anesthetics and their associated adverse effects. The relevant nerve block approaches to anesthetize the brachial plexus for elbow, wrist and hand surgeries are discussed in this article. There is very limited margin for error when performing nerve blocks and multimodal monitoring approach to reduce harm are outlined. Lastly, the importance of obtaining informed consent prior to nerve block procedures should not be overlooked.

Modern anesthetic management for foot and ankle surgery includes a variety of anesthesia techniques including general anesthesia, neuraxial anesthesia, or MAC in combination with peripheral nerve blocks and/or multimodal analgesic agents. The choice of techniques should be tailored to the nature of the procedure, patient comorbidities, anesthesiologist skill level, intensity of anticipated postoperative pain, and surgeon preference.

OBJECTIVE: To determine the tolerability and safety of concurrent peripheral nerve blocks and onabotulinumtoxinA treatment during a single outpatient clinic procedure visit. BACKGROUND: Procedural interventions are available for the treatment of headache disorders. OnabotulinumtoxinA and peripheral nerve blocks are used as alternatives or in addition to oral therapies to reduce the frequency and intensity of migraine attacks. There is currently a lack of safety data focusing on the sequential administration of local anesthetic via peripheral nerve blocks and onabotulinumtoxinA during a single clinical encounter for the treatment of headache. The primary aim of the study was to determine the safety and tolerability of concurrent peripheral nerve blockade and onabotulinumtoxinA injections during a single outpatient clinic procedure visit. We hypothesized that the dual intervention would be safe and well tolerated by patients with chronic migraine and other headache disorders. METHODS: A retrospective chart review was performed using clinical data from patients seen by multiple providers over a 16-month timeframe at one outpatient headache clinic. Patients were identified by procedure codes and those receiving peripheral nerve block(s) and onabotulinumtoxinA injections during a single encounter within the study period were eligible for inclusion. Inclusion criteria were (1) patients 18 years and older who were (2) receiving both peripheral nerve blocks and onabotulinumtoxinA injections for the treatment of chronic migraine. Patients were excluded if they were under age 18, received their procedure outside of the clinic (emergency room, inpatient ward), or were receiving sphenopalatine ganglion blocks. Age- and sex-matched patients who received one procedure, either peripheral nerve blocks or onabotulinumtoxinA, were used for control. The primary outcome of this safety study was the number of adverse events that occurred in the dual intervention group compared to the single intervention control arms. Information regarding adverse events was gathered via retrospective chart review. If an adverse event was recorded, it was then graded by the reviewer utilizing the Common Terminology Criteria for Adverse Events ranging from Grade 1 Mild Event to Grade 5 Death. Additionally, it was noted whether the adverse event led to treatment discontinuation. RESULTS: In total, 375 patients were considered eligible for inclusion in the study. After age and sex matching of controls, 131 patients receiving dual intervention were able to be compared to 131 patients receiving onabotulinumtoxinA alone and 104 patients receiving dual intervention were able to be compared to 104 patients receiving peripheral nerve block(s) alone. The primary endpoint analysis showed no significant difference in total adverse events between dual intervention compared to nerve blocks alone or onabotulinumtoxinA alone. The number of adverse events that led to treatment discontinuation approached but did not reach statistical significance for those receiving dual intervention versus onabotulinumtoxinA alone in the number of adverse events that led to treatment termination (4.6%, 6/131 vs. 0.8%, 1/131, p = 0.065); however, the number of patients who discontinued therapy was not significantly different between those groups (2.3%, 3/131 vs. 0.8%, 1/131; p = 0.314; odds ratio 0.3 [0-3.2]; p = 0.338). CONCLUSIONS: In this retrospective chart review, there was no significant difference in adverse events or therapy discontinuation between patients receiving sequential peripheral nerve block(s) and onabotulinumtoxinA injections versus those receiving either peripheral nerve block(s) or onabotulinumtoxinA injections alone. As a result, we concluded that the combination procedure is likely safe and well tolerated in routine clinical practice.

BACKGROUND: There is limited data showing the benefit of liposomal bupivacaine as part of an Enhanced Recovery After Surgery (ERAS) protocol in reducing opioid use in minimally invasive lobectomies. METHODS: A retrospective observational study compared three cohorts of patients undergoing lobectomies between January 2015 and December 2021. The control group neither received liposomal bupivacaine intraoperatively nor underwent an ERAS protocol. The liposomal bupivacaine cohort only received a nerve block, whereas the ERAS cohort received a nerve block intraoperatively and underwent an ERAS protocol. Primary outcome was post-operative opioid consumption. RESULTS: There were 433 patients in this study (n=87 for controls, n=138 for liposomal bupivacaine alone, and n=208 for ERAS/liposomal bupivacaine). There was a statistically significant difference in the amount of opioids used between the control (43 OME) and liposomal bupivacaine alone cohort (30.5 OME) (p<.001); between control vs. ERAS/liposomal bupivacaine cohort (17 OME) (p<.001); and between liposomal bupivacaine alone and ERAS/liposomal bupivacaine cohorts (p<.001). Hospital stay was not statistically different between the two groups of interest (3 days); however, hospital stay differed from the control (4 days). 30-day readmission was not significantly different between the 3 groups (p=.43). CONCLUSIONS: Liposomal bupivacaine alone as part of a larger ERAS protocol significantly reduced opioid use and hospitalization duration; however, the reduction in opioid use was much greater with incorporation of liposomal bupivacaine into an ERAS protocol rather than in isolation. Prospective studies are needed to determine reproducibility and applicability of liposomal bupivacaine for opioid use reduction in other US hospital systems.
RESUMEN
Pain after hip arthroscopy can be severe, yet we lack a consensus method for non-narcotic analgesia. Here we describe anatomic elements of hip arthroscopy and our current understanding of the relevant sensory innervation as a prelude to the evaluation of locoregional analgesic techniques. Many regional nerve blocks and local anesthetic infiltration techniques are reviewed, including 2 newer ultrasound fascial plane blocks. Further study of targeted, motor-sparing approaches, either ultrasound-guided or under direct surgical visualization is needed.

Background and Aim: Ultrasound popliteal sciatic nerve block (UPSNB) is commonly performed in foot and ankle surgery. This study aims to assess the use of dexmedetomidine and dexamethasone as adjuvants in UPSNB for hallux valgus (HV) surgery, comparing their efficacy in producing motor and sensory block and controlling postoperative pain. The adverse event rate was also evaluated. Methods: This mono-centric retrospective study included 62 adult patients undergoing HV surgery: 30 patients received lidocaine 2% 200 mg, ropivacaine 0.5% 50 mg and dexamethasone 4 mg (Group 1), whereas 32 patients received lidocaine 2% 200 mg, ropivacaine 0.5% 50 mg, and dexmedetomidine 1 mcg/Kg (Group 2). At first, the visual analogue scale (VAS) was evaluated after 48 hours. The other outcomes were time to motor block regression, evaluation of the first analgesic drug intake, analgesic effect, adverse effects (hemodynamic disorders, postoperative nausea and vomiting (PONV)) and patient satisfaction. The continuous data were analyzed with student's t-test and the continuous one with χ2. Statistical significance was set at a p-value lower than 0.05. Results: No significant difference was found in VAS after 48 hours (4.5 ± 1.6 vs 4.7 ± 1.7, p = 0.621) to motor block regression (18.9 ± 6.0 vs 18.7 ± 6, p = 0.922). The number of patients that took their first analgesic drug in the first 48 h (p = 0.947 at 6 hours; p = 0.421 at 12 hours; p = 0.122 at 24 hours and p = 0.333 at 48 hours) were not significant. A low and similar incidence of intraoperative hemodynamic disorders was recorded in both groups (hypotension p = 0.593; bradycardia p = 0.881). Neither PONV nor other complication was found. Patients in Group 1 reported a lower degree of interference with sleep (p = 0.001), less interference with daily activities (P = 0.002) and with the affective sphere (P = 0.015) along with a more satisfactory postoperative pain management (p < 0.001) as compared to Group 2. Conclusion: No significant differences were observed in the duration of motor and sensory blockade between patients in both groups. Additionally, both groups showed good pain control with a low rate of adverse effects, even if there was no clinical difference between the groups. However, patients who received dexamethasone reported experiencing less interference with their sleep, daily activities and overall emotional well-being, and overall pain control.

CONTEXT: Pain is a common experience in people living with cancer. Concerns around opioid prescribing have seen a move toward a multi-modality management approach, which includes interventional pain procedures. PURPOSE: In this paper we discuss the interventional pain procedures used to treat cancer pain at two major tertiary centers in Australia. METHODS AND RESULTS: This expert review provides practical insights on cancer pain management from healthcare providers in different specialties. These insights can be used to guide the management of a wide range of cancer pain types. CONCLUSIONS: Furthermore, this review identifies the need for a systematic and comprehensive approach to the management of cancer pain that is broader than that of a single specialty. With recent advances in pain management procedures, an interdisciplinary approach is essential in order to provide an up to date, patient tailored approach to pain management. This review will help inform the development of a cancer pain intervention registry.

PURPOSE OF REVIEW: Postcraniotomy headache (PCH) is a common adverse event and can lead to various complications and decreased quality of life. RECENT FINDINGS: To reduce postcraniotomy pain and associated complications, a multimodal pain therapy including analgesics, analgesic adjuncts, and regional anesthesia is essential. The use of opioids should be minimized to facilitate prompt postoperative neurosurgical assessment. Here, we provide an update on the latest evidence regarding the role of scalp nerve blocks in the pain management of patients undergoing craniotomy procedure. Nerve blocks are effective in alleviating postoperative pain after craniotomy. Scalp blocks contribute to lower pain levels and less opioid consumption in the first 48 h following surgery. Moreover, there is a significant decrease in patients suffering from PONV among patients who receive scalp block.

Introduction Platelet-rich plasma (PRP), a solution of concentrated platelets, has been widely used to promote wound repair and tissue regeneration. In the treatment of pattern hair loss, platelets in PRP secrete an abundance of growth factors, including platelet-derived growth factor (PDGF), fibroblast growth factor(FGF), and many more, which stimulate and increase signaling molecules and accelerate cell proliferation. In the PRP treatment for hair regrowth, the supratrochlear nerve (STN) block and supraorbital nerve (SON) block are given to anesthetize the scalp up to the vertex except for the temporal region. The ring block is the common local anesthetic technique used by infiltrating local anesthetic agents around the target area. The primary objectives were to compare the pain and anesthetic success rates produced by regional nerve blocks and ring blocks. Materials and methods A sample size of 100 patients undergoing PRP treatment for hair regrowth were taken as the subjects for the study. Patients were allotted into two groups by randomization. Group 1 was given regional nerve blocks as the anesthetic technique used for local anesthesia, and group 2 was given ring blocks. In the study group, STN and SON blocks as the regional nerve blocks were given 2% lignocaine with 1:80000 adrenaline to anesthetize the area, and the PRP was injected from the anterior hairline up to the vertex of the scalp, not involving the occipital and temporal regions. In the control group, a ring block was given for the same procedure. Participants from both groups were assessed for the pain and analgesia caused by ring block and regional nerve blocks using the visual analog scale (VAS). Results A mean rank of 30.28 was observed for the regional nerve block technique, and a mean rank of 70.72 was observed for the ring block technique. A p-value of 0.00 that is <0.05 was observed, which shows there is a significant difference in the pain and the analgesia experienced by the subjects between the two groups, during and three hours after the procedure. Conclusion PRP is one of the most commonly used treatments for hair regrowth. The ring block is the common local anesthetic technique used for producing anesthesia, while regional nerve blocks are more effective in producing local anesthesia. This study proves that STN and SON blocks are better anesthetic techniques than the ring block technique for PRP treatment in hair growth.
