Abstract
OBJECTIVES Transversus abdominis plane block is a regional anaesthesia technique that has proven to be effective for postoperative pain reduction in different abdominal surgical procedures. This study evaluated its efficacy on post laparoscopic hysterectomy pain intensity and analgesic consumption. MATERIALS AND METHODS Randomized controlled trial which included 40 patients scheduled for laparoscopic hysterectomy, enrolled in 2 groups: transversus abdominis plane block+systemic analgesia (Group 1; n=20), versus systemic analgesia (Group 2; n=20). Opioid consumption within the first 24 postoperative hours, pain intensity scores at 60min, 2, 8 and 24h after surgery, adverse events related to systemic analgesia and time to hospital discharge were evaluated and registered. RESULTS We found no differences between both groups in opioid consumption (10mg vs. 7mg; P=.2) and pain scores (NVS) within the first 24 postoperative hours, at 60min (3 vs. 5; P=.65), 120min (0 vs. 2; P=.15), 8 and 24h (0 vs. 0; P>.50) for the last 2 points in time analysed. Adverse events related to medication and time to hospital discharge showed similar results. CONCLUSIONS Adding a transversus abdominis plane block technique to opioid PCA does not seem to improve postoperative pain management in laparoscopic hysterectomy. Patient preparation time and costs could be incremented and complications (although rare) related to the technique could appear.

Abstract
Multimodal analgesia provides quality analgesia, with fewer side effects due to the use of combined analgesics or analgesic techniques. Regional anaesthesia plays a fundamental role in achieving this goal. The different techniques of regional anaesthesia that include both peripheral and central blocks in either a single dose or in continuous infusion help to modulate the nociceptive stimuli that access the central level. The emergence of the ultrasound as an effective system to perform regional anaesthesia techniques has allowed the development of new regional anaesthesia techniques that formerly could not be carried out since only neurostimulation or skin references were used. It is essential to take into account that even with effective blocking it is advisable to associate other drugs by other routes, in this way we will be able to reduce the required doses individually and attempt to achieve a synergistic, not purely additive, effect.

Abstract
UNLABELLED Local anaesthetic injection between the tibial and commmon peroneal nerves within connective tissue sheath results in a predictable diffusion and allows for a reduction in the volume needed to achieve a consistent sciatic popliteal block. Using 3D ultrasound volumetric acquisition, we quantified the visible volume in contact with the nerve along a 5cm segment. METHODS We included 20 consecutive patients scheduled for bunion surgery. Ultrasound guided popliteal block was performed using a posterior, out of plane approach at the level of división of the sciatic nerve. Thirty ml of mepivacaine 1.5% and levobupivacaine 0.5% were slowly injected while assessing the injection pressure and the diffusion of the local anaesthetic. Volumetric acquisition was performed before and after the block to quantify the the volume of the sciatic nerve and the volume of the surrounding hypoechoic halo contained inside the connective tissue in a 5cm segment. RESULTS All blocks were successful within 20min after the injection. The total estimated volume contained inside the common connective tissue sheath was 6.8±2.6cm3. Of this, the volume of the halo sorrounding the nerve was 4.4±1.7cm3 and the volume inside the sciatic nerve was 2.4±1.7cm3. CONCLUSIONS The volume of local anaesthetic in close contact with the sciatic nerve can be estimated by volumetric acquisition. Our results suggest that the effective volume of local anaesthetic needed for a successful sciatic popliteal block could be reduced to less than 7ml.

Abstract
INTRODUCTION The quality of postoperative recovery is one of the most important among all the quality indicators used in clinical situations. This is even more important after cancer surgery. Our aim was to evaluate this after non-reconstructive breast surgery under general anesthesia and paravertebral blockade or serratus-intercostal plane blockade, in the early and late post-operative period. MATERIAL AND METHODS A prospective observational study was conducted on 60 patients (25 paravertebral blockade group and 35 serratus-intercostal plane blockade group) scheduled for non-reconstructive breast surgery during a 6 month period. Every patient received general anaesthesia and were randomised to receive either paravertebral blockade or serratus-intercostal plane blockade. The quality of post-anaesthetic recovery was quantified by Postoperative Quality Recovery Scale, which is used to assess physiological, nociceptive, emotional, autonomy, cognitive and general state domains at different times: baseline (before surgery), 15min after the end of surgery, at discharge to home, and one month after surgery. RESULTS A total recovery of 95.93% was achieved in the early postoperative period (15min PACU), 99.07% at discharge to home, and 99.25% at one month after the intervention. No significant differences were found between groups in total score or in each evaluated area. CONCLUSIONS A progressive improvement was observed in the scores assessed with the Postoperative Quality Recovery Scale, reaching values that would allow the discharge to home and early return to usual active life from the immediate postoperative period, with no significant differences between the 2 analgesic techniques. Savings in opioid use and the excellent recovery were observed in all measured domains observed.

Abstract
Eisenmenger syndrome (ES) is a complex combination of cardiovascular abnormalities defined as pulmonary hypertension with investment or bidirectional flow through an intracardiac or aortopulmonary communication, usually secondary to a congenital heart disease not resolved promptly. It carries a significant risk of perioperative mortality, with an incidence close to 30% for non-cardiac surgery. We report the anaesthetic management in a ES patient undergoing breast surgery, which was successfully performed under general anaesthesia combined with thoracic analgesic blocks. The main pathophysiological implications of this syndrome are discussed, emphasizing the importance of appropriate preoperative evaluation with thorough assessment of associated risks, careful intraoperative management, and postoperative care, which should be initially performed in a critical care unit. The need to individualize and tailor the choice of drugs and anesthetic technique to the hemodynamic condition of the patient and the surgical procedure is highlighted.

Abstract
OBJECTIVE A survey was conducted in order to obtain a profile of the practice of regional anesthesia in South America, and determine the limitations of its use. METHODS After institutional ethics committee approval, a link to an online questionnaire was sent by e-mail to anaesthesiologists in Argentina, Bolivia, Chile, Colombia, Panamá, Paraguay, Perú, and Uruguay. The questionnaire was processed anonymously. RESULTS A total of 1,260 completed questionnaires were received. The results showed that 97.6% of the anaesthesiologists that responded used regional anaesthesia in clinical practice, 66.9% performed peripheral nerve block (PNB) regularly, 21.6% used continuous PNB techniques, and 4.6% used stimulating catheters. The primary source of training was residency programs. As regards PNB, the most common performed were interscalene (52.3%), axillary (45.1%), femoral (43.2%), and ankle block (43%). As regards the localisation technique employed, 16% used paraesthesia, 44.2% used a peripheral nerve stimulator, and 18.1% ultrasound guidance. CONCLUSIONS Regional anaesthesia and PNB are commonly used among South American anaesthesiologists. Considering that each country has its own profile for use, this profile should guide training in clinical practice, especially in residency programs.

Abstract
BACKGROUND Among the many changes caused by a surgical insult one of the least studied is postoperative immunosuppression. This phenomenon is an important cause of infectious complications of surgery such as surgical site infection or hospital acquired pneumonia. One of the mechanisms leading to postoperative immunosuppression is the apoptosis of immunological cells. Anesthesia during surgery is intended to minimize harmful changes and maintain perioperative homeostasis. The aim of the study was evaluation of the effect of the anesthetic technique used for total knee replacement on postoperative peripheral blood lymphocyte apoptosis. METHODS 34 patients undergoing primary total knee replacement were randomly assigned to two regional anesthetic protocols: spinal anesthesia and combined spinal-epidural anesthesia. 11 patients undergoing total knee replacement under general anesthesia served as control group. Before surgery, immediately after surgery, during first postoperative day and seven days after the surgery venous blood samples were taken and the immunological status of the patient was assessed with the use of flow cytometry, along with lymphocyte apoptosis using fluorescent microscopy. RESULTS Peripheral blood lymphocyte apoptosis was seen immediately in the postoperative period and was accompanied by a decrease of the number of T cells and B cells. There were no significant differences in the number of apoptotic lymphocytes according to the anesthetic protocol. Changes in the number of T CD3/8 cells and the number of apoptotic lymphocytes were seen on the seventh day after surgery. CONCLUSION Peripheral blood lymphocyte apoptosis is an early event in the postoperative period that lasts up to seven days and is not affected by the choice of the anesthetic technique.

Abstract
Ectodermal dysplasias are rare conditions with a triad of hypotrichosis, anodontia and anhidrosis. In literature review there have been only a few reports of anesthetic management of patients with ectodermal dysplasias. Hyperthermia is a very serious risk which may occur due to the defect of sweat glands. The present case involves a 10-year-old child with ectodermal dysplasia who presented with an acute abdomen and was considered for an emergency surgery. Our aim was to demonstrate the successful management of this case using a combination of general and epidural anesthesia. It is important for anesthesiologist to have information about this syndrome in case of emergency operations, since it can prevent serious complications and even save lives.

Abstract
OBJECTIVE To determine whether the location of the sciatic nerve (SN) at the popliteal fossa is related to anthropometric variables in the adult population, and to identify possible anatomical variations and their possible implications for clinical practice. MATERIALS AND METHOD Prospective observational study in elective ambulatory surgery patients. Patients were examined using ultrasound, looking at depth, laterality and distance at which the SN bifurcates at the level of the popliteal fossa. These measurements were linked to gender and the anthropometric data of the patients. RESULTS A total of 62 patients were included, with 124 measurements. A statistically significant association was found between SN depth and the diameter of the thigh measured at 10 cm from the popliteal crease (P<.001). Mean depth: 3.32 ± 0.8 cm, mean laterality: 1.43 ± 0.9 cm, mean SN bifurcation distance: 61.78 ± 12 mm and mean SN diameter: 7.45 ± 1.17 mm. There were no statistical differences when comparing the measured variables with the age and gender. Similar results were obtained between measurements when comparing both lower limbs in the same patient. There was no statistical difference between height and distance at which the SN bifurcates. CONCLUSIONS The depth and laterality of SN are independent of gender, weight and height. The depth at which the SN is located at the level of the popliteal fossa is related to the diameter of the thigh. The bifurcation of SN in popliteal fossa is not related to height.

Abstract
OBJECTIVE Holmium laser enucleation of the prostate (HoLEP) is an alternative to prostatic adenomectomy for the surgical treatment of benign prostatic hypertrophy. We analyzed our learning curve for this technique, and we compared it in a secondary manner with prostatic adenomectomy. MATERIALS AND METHODS A retrospective comparative study was conducted that included the first 100 cases of HoLEP performed in our center and the latest 50 cases of retropubic adenomectomy. We collected data on the patients, the surgery, the anesthesia, the perioperative variables, the anesthesia complications and the postoperative variables, with a 6-month follow-up. We analyzed the learning curve without mentors for HoLEP and compared the characteristics of HoLEP in 2 separate phases (learning and stabilization phases) with the latest retropubic prostatic adenomectomies performed. RESULTS Intradural anesthesia was the most common technique. The transfusion needs, length of stay (P<.01) and postoperative morbidity were lower for HoLEP than for adenomectomy. However, the retropubic adenomectomy group had larger initial prostate volumes (P<.001) and shorter surgical times (P<.001). Better surgical performance (P<.001) and a lower incidence of complications were observed in the HoLEP-B group (once the learning curve had been overcome) compared with the HoLEP-A group. CONCLUSION In our center, HoLEP was introduced as a valid alternative to open retropubic adenomectomy, with excellent results in terms of morbidity and reduced hospital stay. In terms of the learning curve, we consider that approximately 50 patients (without mentor) is an appropriate cutoff. Local anesthesia is a good choice for the anesthesia technique.

Abstract
BACKGROUND AND OBJECTIVES Hypertrophic pyloric stenosis is a relatively common affection of gastrointestinal tract in childhood that results in symptoms, such as projectile vomiting and metabolic disorders that imply a high risk of aspiration during anesthetic induction. In this way, the carrying out of a technique with general anesthesia and intravenous rapid sequence induction, preoxygenation and cricoid pressure are recommended. After the correction of systemic metabolic alkalosis and pH normalization, cerebrospinal fluid can keep a state of metabolic alkalosis. This circumstance, in addition to the residual effect of neuromuscular blocking agents, inhalant anesthetics and opioids could increase the risk of postoperative apnea after a general anesthesia. CASE REPORT We present the successful management in 3 neonates in those a pyloromyotomy was carried out because they had presented congenital hypertrophic pyloric stenosis. This procedure was done under general anesthesia with orotracheal intubation and rapid sequence induction. Then, ultrasound-guided paravertebral block was performed as analgesic method without the need for administrating opioids within intraoperative period and keeping an appropriate analgesic level. CONCLUSIONS Local anesthesia has demonstrated to be safe and effective in pediatric practice. We consider the ultrasound-guided paravertebral block with one dose as a possible alternative for other local techniques described, avoiding the use of opioids and neuromuscular blocking agents during general anesthesia, and reducing the risk of central apnea within postoperative period.

Abstract
BACKGROUND AND OBJECTIVES This study shows how the diffusion of the anesthetic into the sheath occurs through the axillary infraclavicular space and hence proves the efficacy of the anesthetic block of the brachial plexus, and may thereby allow a consolidation of this pathway, with fewer complications, previously attached to the anesthesia. MATERIALS AND METHODS 33 armpits of adult cadavers were analyzed and unfixed. We injected a solution of neoprene with latex dye in the infraclavicular space, based on the technique advocated by Gusmão et al., and put the corpses in refrigerators for three weeks. Subsequently, the specimens were thawed and dissected, exposing the axillary sheath along its entire length. RESULTS AND DISCUSSION Was demonstrated involvement of all fasciculus of the plexus in 51.46%. In partial involvement was 30.30%, 18.24% of cases the acrylic was located outside the auxiliary sheath involving no issue. CONCLUSIONS The results allow us to establish the infraclavicular as an effective and easy way to access plexus brachial, because the solution involved the fascicles in 81.76% partially or totally, when it was injected inside the axillary sheath. We believe that only the use of this pathway access in practice it may demonstrate the efficiency.

Abstract
INTRODUCTION The use of ultrasound in regional anesthesia allows reducing the dose of local anesthetic used for peripheral nerve block. The present study was performed to determine the minimum effective concentration (MEC90) of bupivacaine for axillary brachial plexus block. METHODS Patients undergoing hand surgery were recruited. To estimate the MEC90, a sequential up-down biased coin method of allocation was used. The bupivacaine dose was 5 mL for each nerve (radial, ulnar, median, and musculocutaneous). The initial concentration was 0.35%. This concentration was changed by 0.05% depending on the previous block; a blockade failure resulted in increased concentration for the next patient; in case of success, the next patient could receive or reduction (0.1 probability) or the same concentration (0.9 probability). Surgical anesthesia was defined as driving force ≤ 2 according to the modified Bromage scale, lack of thermal sensitivity and response to pinprick. Postoperative analgesia was assessed in the recovery room with numeric pain scale and the amount of drugs used within 4h after the blockade. RESULTS MEC90 was 0.241% [R(2): 0.978, confidence interval: 0.20-0.34%]. No patient, with successful block, reported pain after 4h. CONCLUSION This study demonstrated that ultrasound guided axillary brachial plexus block can be performed with the use of low concentration of local anesthetics, increasing the safety of the procedure. Further studies should be conducted to assess blockade duration at low concentrations.

Abstract
Non-invasive ventilation is an accepted treatment modality in both acute exacerbations of respiratory diseases and chronic obstructive lung disease. It is commonly utilized in the intensive care units, or for postoperative respiratory support in post-anesthesia care units. This report describes intraoperative support in non-invasive ventilation to neuroaxial anesthesia for an emergency upper abdominal surgery.

Abstract
BACKGROUND AND OBJECTIVES This study shows how occurs the diffusion of the anesthetic into the sheath through the axiliary infraclavicular space and hence prove the efficacy of the anesthetic block of the brachial plexus, and may thereby allow a consolidation of this pathway, with fewer complications, previously attached to the anesthesia. MATERIALS AND METHODS 33 armpits of adult cadavers were analyzed and unfixed. We injected a solution of neoprene with latex dye in the infraclavicular space, based on the technique advocated by Gusmão et al., and put the corpses in refrigerators for three weeks. Subsequently, the specimens were thawed and dissected, exposing the axillary sheath along its entire length. RESULTS AND DISCUSSION Was demonstrated involvement of all fasciculus of the plexus in 51.46%. In partial involvement was 30.30%, and 18.24% of cases the acrylic was located outside the auxiliary sheath involving no issue.

Abstract
INTRODUCTION Several nerve blocks have recently been used for pain treatment in breast surgery. The main objective of our study was to determine the efficacy and safety of ultrasound-assisted blocking of the anterior and lateral cutaneous branches of the intercostal nerves in the mid-axillary line for non-reconstructive breast and axilla surgery. MATERIAL AND METHODS A prospective observational study was conducted on 30 patients scheduled for non-reconstructive breast and axilla surgery. An intercostal branches block was performed in the mid-axillary line with 0,5% levobupivacaine (3ml in each intercostal space). Clinical efficacy was assessed by standard intraoperative hemodynamic response to surgical stimulus and the need for opioids, and in the postoperative period, by assessing pain intensity as a verbal numerical scale and the need for rescue treatment. We also evaluated the quality of sleep the first night after surgery, any adverse events that occurred, and the satisfaction of patients and surgeons with the anesthetic technique. RESULTS The intercostal branches block in the mid-axillary line was effective in most cases, with only 2 patients requiring intraoperative opioids, and in one case analgesic rescue was necessary in the postoperative period. The duration of postoperative analgesia was 19±4h. There were no notable adverse events or complications. The satisfaction with the chosen technique was assessed as "very good" in all patients, and by 97% of the surgeons. CONCLUSIONS Intercostal branches block in the mid-axillary line provides adequate intraoperative and postoperative analgesia for non-reconstructive breast and axilla surgery. It is a simple, reproducible technique in most patients of this study, with an easy to understand ultrasound anatomy, in which adequate analgesia could be provided through a single puncture, and may be an alternative to neuroaxial blocks.
