RESUMEN
OBJECTIVE: To assess whether music therapy (MT) is effective to reduce pain during daily personal hygiene care (DPHC), a procedure performed in all patients in a pediatric intensive care unit. METHODS: Fifty critically ill children were enrolled in a crossover controlled clinical trial with random ordering of the intervention, that is, passive MT, and standard conditions, and blind assessment of pain on film recordings. The primary outcome was variation of the Face Legs Activity Cry Consolability (FLACC) score (range, 0-10) comparing before and during DPHC. Secondary outcomes were changes in heart rate, respiratory rate, and mean arterial blood pressure, and administration of analgesic or sedative drugs during DPHC. Mixed-effects linear model analysis was used to assess effect size (95% CI). RESULTS: The median (Q25-Q75) age and weight of the patients were 3.5 years (1.0-7.6 years) and 15.0 kg (10.0-26.8 kg). Consecutive DPHC were assessed on days 3 (2-5) and 4 (3-7) of hospitalization. In standard conditions, FLACC score was 0.0 (0.0-3.0) at baseline and 3.0 (1.0-5.5) during DPHC. With MT, these values were, respectively, 0.0 (0.0-1.0) and 2.0 (0.5-4.0). Rates of FLACC scores of >4 during DPHC, which indicates severe pain, were 42% in standard conditions and 17% with MT (P = .013). Mixed-effects model analysis found smaller increases in FLACC scores (-0.54 [-1.08 to -0.01]; P = .04) and heart rate (-9.00; [-14.53; -3.40]; P = .001) with MT. CONCLUSIONS: MT is effective to improve analgesia in critically ill children exposed to DPHC. TRIAL REGISTRATION: This study was recorded (April 16, 2019) before patient recruitment on the National Library of Medicine registry (NCT03916835; https://clinicaltrials.gov/ct2/show/NCT03916835).

BACKGROUND: Walking ability is a key factor in enhanced recovery after foot ambulatory surgery. Plantar compartment block offers an analgesic alternative to popliteal sciatic nerve block (PSNB) for hallux valgus surgery. The objective of this study was to compare these two regional anesthesia strategies on patients' ability to recover a painless unaided walk. METHODS: This prospective double-blinded (patient; observing anesthesiologist) randomized study compared patients scheduled for hallux valgus surgery receiving PSNB with 1% mepivacaine, then combined plantar and peroneal nerve blocks (PCB group) with ropivacaine 0.5% and dexamethasone, or PSNB with ropivacaine 0.5% and dexamethasone (control group). The primary outcome was the patient's ability to walk unaided 6 h after PSNB. The test was performed on a GAITRite® spatio-temporal gait analysis mat. During three days, the number of patient steps, pain levels, rescue analgesics, patient's experience and adverse events were assessed. RESULTS: Sixty patients were included and 59 were analyzed. The number of patients walking unaided on the GAITRite® mat was significantly higher in the PCB group (21/30, 70%) than in the control group (4/29, 13.8%; p<0.001). Gait quality using the Functional Ambulation Profile score was 63±13.6 in the PCB group and 49.5±4.7 in the control group (p<0.001). Median time to free ambulation at home was significantly lower in the PCB group (9 h [8.2-11.8]) than in the control group (33.5 h [24-47]; p<0.001). Postoperative pain did not differ between the groups (ß=-0.41 [-1.78 to 0.95]; p=0.548). The number of steps at day 3, the time of first rescue analgesic, the number of patients using rescue analgesia, consumption of morphine, and patient's experience did not differ between the groups. CONCLUSION: PCB decreased the time to return to unaided walking, with improved gait, compared with PSNB, improving effective analgesia and low consumption of rescue analgesics. This innovative regional anesthesia strategy enhanced recovery after surgery.
RESUMEN
BACKGROUND: Reducing perioperative anxiety and controlling pain in children are essential to optimise recovery and outcomes for both children and their parents. By acting on sensory and affective modulation of anxiety and pain, hypnosis is widely used in medical care, especially in anaesthesia. This randomised controlled clinical trial was designed to compare general anaesthesia and intraoperative hypnosis support for perioperative management of children undergoing superficial surgery. METHODS: Children aged 7-16 yr scheduled for day-case superficial surgery were included and randomly assigned to one of the following two groups: general anaesthesia group or hypnosis group. The primary outcome was length of hospital stay. Child and parent anxiety, child pain, and the occurrence of postoperative negative behavioural changes were also evaluated. RESULTS: Sixty children of mean age 10.3 (standard deviation: 2.6) yr were enrolled in the study. Hypnosis was successful in all but one case. The median (25th-75th percentile) length of hospital stay was shorter in the hypnosis group (120 [95-145] vs 240.5 [218-275] min; P<0.001). The general anaesthesia group was associated with a greater incidence of high levels of preoperative anxiety in children (30 vs 11%; P=0.001) and parents (55 vs 30%; P=0.05). Pain scores did not differ between groups. No negative postoperative behavioural changes were reported. CONCLUSIONS: In children aged 7-16 yr, hypnosis appears to be feasible and accepted. The quality of the perioperative experience and the rapid recovery support the use of hypnosis as an effective and safe alternative to general anaesthesia for paediatric superficial surgery. CLINICAL TRIAL REGISTRATION: NCT02505880.

BACKGROUND: The optimal approach to improving patient experience and analgesia after ambulatory orthopaedic surgery remains unclear. METHODS: This multicentre, randomised clinical trial compared single-injection nerve block analgesia with home delivery of continuous nerve block analgesia by remote-controlled electronic pump. The primary outcome was patient-reported satisfaction (Evaluation du Vecu de l'Anesthesie Generale [EVAN-G]; 0-100) assessed on postoperative Day 2. Secondary outcomes focused on pain, opioid consumption, quality of rehabilitation, activity tracking using a wearable electronic device, and 90-day quality of life. RESULTS: We randomly assigned 294 patients to continuous pump delivery or single injection. For subjects with normal level of pain catastrophising (Pain Catastrophizing Scale <30; n=211), median global EVAN-G was higher with the electronic pump compared with the single injection (78 [69-86] vs 72 [63-84]; P=0.03), as were pain satisfaction scores (P=0.01). For the maximum pain levels, the numerical rating scale score was 2.0 (1.0-5.0) in the electronic-pump group vs 5.0 (3.0-7.0) in the single-injection group on the first 2 days after surgery (P<0.0001). Total opioid consumption in morphine equivalent was higher with single injection (mean [standard deviation]): 70.5 [73.8] vs 31.9 [54.2] mg; P<0.01). The groups did not differ in early rehabilitation on Day 1 or quality of life on Day 45. Electronic activity tracking indicated higher activity in the electronic-pump group (P<0.01). CONCLUSIONS: Self-reported patient satisfaction at home was better with continuous nerve block analgesia via electronic pump vs single injection, without impairing early rehabilitation. Single-injection analgesia was associated with higher pain levels and opioid consumption and lower satisfaction. Patient catastrophising negatively affected the experience of pain.

BACKGROUND: Pain management is important for ensuring early mobilization after hip arthroplasty; however, the optimal components remain controversial. Recently, the quadratus lumborum block has been proposed as an analgesic option. The current study tested the hypothesis that the posterior quadratus lumborum block combined with multimodal analgesia decreases morphine consumption after hip arthroplasty. METHODS: This study was a prospective, randomized, double-blind, placebo-controlled trial. Before general anesthesia, 100 participating patients scheduled for elective total hip arthroplasty were randomly allocated to receive a 30-ml injection posterior to the quadratus lumborum muscle with either 0.33% ropivacaine (n = 50) or normal saline (n = 50). For all patients, multimodal analgesia included systematic administration of acetaminophen, ketoprofen, and a morphine intravenous patient-controlled analgesia. The primary outcome was total intravenous morphine consumption in the first 24 h. Secondary outcomes recorded intraoperative sufentanil consumption; morphine consumption in the postanesthesia care unit; pain scores at extubation and at 2, 6, 12, and 24 h; motor blockade; time to first standing and ambulation; hospital length of stay; and adverse events. RESULTS: There was no significant difference in the 24-h total morphine consumption (ropivacaine group, median [interquartile range], 13 [7 to 21] versus saline group, 16 [9 to 21] mg; median difference, -1.5; 95% CI, -5 to 2; P = 0.337). Pain scores were not different between the groups (ß = -0.4; 95% CI, -0.9 to 0.2; P = 0.199). There was no statistical difference between the two groups in intraoperative sufentanil consumption, morphine consumption in the postanesthesia care unit, motor blockade, times to first standing (median difference, 0.83 h; 95% CI, -1.7 to 3.4; P = 0.690) and ambulation (median difference, -1.85 h; 95% CI, -4.5 to 0.8; P = 0.173), hospital length of stay, and adverse events. CONCLUSIONS: After elective hip arthroplasty, neither morphine consumption nor pain scores were reduced by the addition of a posterior quadratus lumborum block to a multimodal analgesia regimen.

BACKGROUND: Nerve damage can occur after peripheral nerve block (PNB). Ultrasound guidance does not eliminate the risk of intraneural injection or nerve injury. Combining nerve stimulation and injection pressure (IP) monitoring with ultrasound guidance has been suggested to optimize needle tip location in PNB. In this prospective observational study, we hypothesized that measured pairs of IP and minimum intensity of stimulation (MIS) might differentiate successive needle tip locations established by high-resolution ultrasound during PNB. METHODS: For this exploratory study, 240 observations for 40 ultrasound-guided PNBs were studied in 28 patients scheduled for orthopedic surgery. During the progression of the needle to the nerve observed by ultrasonography, the IP was measured continuously using a computerized pressure-sensing device with a low flow rate of solution. Stimulation thresholds and electrical impedance were obtained by an impedance analyzer coupled to the nerve stimulator at 6 successive needle positions. The median (quartile) or mean (95% confidence interval [CI]) was reported. A mixed model analysis was used, and the sample was also explored using a classification and regression tree (CART) algorithm. RESULTS: Specific combinations of IP and MIS were measured for subcutaneous, epimysium contact, intramuscular, nerve contact (231 mm Hg [203-259 mm Hg] and 1.70 mA [1.38-2.02 mA]), intraneural location (188 mm Hg [152-224 mm Hg] and 0.58 mA [0.46-0.70 mA]), and subparaneural location (47 mm Hg [41-53 mm Hg] and 1.35 mA [1.09-1.61 mA]). The CART algorithm shows that the optimal subparaneural needle tip position might be defined by the lowest pressure (<81.3 mm Hg) and MIS (<1.5 mA) cutoffs. CONCLUSIONS: Our exploratory study evaluated concepts to generate hypotheses. The combinations of IP and MIS might help the physician during a PNB procedure. A low IP and low MIS might confirm a subparaneural location, and a high IP and a low MIS might be an alert for the intraneural location of the needle tip.

BACKGROUND: In orthopedic surgery, a patient blood management program (PBM) has been proposed to reduce blood transfusion. The aim of this observational study was to assess, within a PBM, the specific efficacy of preoperative erythropoietin (EPO). STUDY DESIGN AND METHODS: In a single hospital, 723 patients undergoing elective primary hip or knee arthroplasty were prospectively studied. The PBM included EPO if preoperative hemoglobin was lower than 13 g/dL, intraoperative administration of tranexamic acid, use of recommended transfusion thresholds, and postoperative infusion of iron. Blood transfusion and hemoglobin were noted until discharge. Major thromboembolic or cardiovascular events were assessed during admission and 1 month after discharge. RESULTS: Transfusion was noted in 2.5% patients with EPO. Transfusion rate was higher in patient for whom EPO was not indicated (13.6% transfusion rate; odds ratio [OR], 13.7; 95% confidence interval [CI], 2.6-66; p = 10-3 ) or if erythropoietin was indicated but not administrated (36.8% transfusion rate; OR, 18.2; 95% CI, 3.9-84.5; p < 10-3 ). Hemoglobin was significantly higher during the postoperative period in patients with erythropoietin. At hospital discharge, 57% of patients were anemic if EPO was used compared to 88% when EPO was not indicated and 87% when EPO was indicated but not administered (p < 10-6 ). There were no significant differences in the odds of major complications between patients with or without EPO. CONCLUSIONS: Within a PBM, preoperative treatment of anemia with EPO decreased both the rate of blood transfusion and postoperative anemia. Further studies are necessary to confirm these results.

BACKGROUND: The transversus abdominis plane (TAP) block has become a common regional anesthesia technique for pain management in a wide variety of abdominal procedures. Evidence to support any particular local anesthetic regimen as well as pharmacokinetic and systemic toxicity risks of TAP block remain insufficiently studied in children. The aim of this study was to compare the analgesic effects and investigate pharmacokinetic profile of levobupivacaine after ultrasound-guided TAP block using a low volume/high concentration (LVHC) or a high volume/low concentration (HVLC) solution in children. METHODS: This prospective randomized study included children scheduled for day-case inguinal surgery. Children were randomized to receive TAP block using 0.4 mg·kg levobupivacaine as either HVLC (0.2 mL·kg of 0.2% levobupivacaine) or LVHC (0.1 mL·kg of 0.4% levobupivacaine). The primary outcome was the number of children who required opioid rescue analgesia postoperatively. Pharmacokinetic profile study of levobupivacaine was also performed. RESULTS: Seventy patients were equally randomized, and 65 were included in the final analysis. Seventy-one percent of patients did not require any postoperative opioid analgesia. The number of patients who received rescue analgesia was 12 (35%) in the LVHC group and 7 (23%) in the HVLC group (relative risk, 0.64; 95% confidence interval [CI], 0.29-1.42; P = .26). Mean pain scores (FLACC [faces, legs, activity, cry, and consolability]) at postanesthesia care unit discharge did not differ between LVHC and HVLC groups, respectively, 0.39 ± 0.86 and 1 ± 1.71 with mean group difference -0.60 (95% CI, -1.27 to 0.06; P = .08). The pharmacokinetic profile of levobupivacaine was comparable in the 2 groups: the mean total and free levobupivacaine peak concentrations were 379 ± 248 and 3.95 ± 3.16 ng·mL, respectively, occurring 22.5 ± 11 minutes after injection. The highest total and free levobupivacaine concentrations collected, respectively, 1360 and 15.1 ng·mL, remained far below theoretical toxic thresholds. CONCLUSIONS: In children, quality of postoperative pain control provided by TAP block using levobupivacaine 0.4 mg·kg administered as either HVLC or LVHC did not differ and was associated with a very low risk of local anesthetic systemic toxicity.

BACKGROUND: Recently, the European prospective observational multicenter cohort study, APRICOT, reported anesthesia techniques and complications in more than 31 000 pediatric procedures. The main objective of this study was to analyze the current practice in regional anesthesia in the 33 countries that participated to APRICOT. METHODS: Data on regional anesthesia techniques were extracted from the database of APRICOT (261 centers across 33 European countries). All children, aged from birth to 16 years old, were eligible for inclusion during a 2-week period. Type of regional anesthesia, whether used awake or with sedation or general anesthesia, techniques of guidance, and the drugs administered were analyzed. RESULTS: Regional anesthesia was used in 4377 pediatric surgical procedures. The large majority was performed under general anesthesia with central blocks and truncal blocks, representing, respectively, 42.6% and 41.8% of performed techniques. Caudal blocks represented 76.9% of all central blocks. The penile and ilioinguinal/iliohypogastric blocks were the most commonly performed truncal blocks. Anesthetists used mainly anatomical landmarks; ultrasound guidance was applied in only 23.8% of cases. A wide variability of practices was observed in terms of regional anesthesia techniques and local anesthetics among the participating European countries. No serious complications were reported. CONCLUSION: These data show a large predominance of central and truncal blocks in APRICOT study. Ultrasound guidance was mainly used for peripheral nerve blocks while central blocks were performed using landmark techniques.

WHAT WE ALREADY KNOW ABOUT THIS TOPIC: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Preoperative administration of epoetin-α with iron is commonly used in anemic patients undergoing major orthopedic surgery, but the optimal route of iron intake is controversial. The aim of this study was to compare the clinical effects of erythropoietin in combination with oral or intravenous iron supplementation. METHODS: This study was a prospective, randomized, single-blinded, parallel arm trial. Patients scheduled for elective hip or knee arthroplasty with hemoglobin 10 to 13 g/dl received preoperative injections of erythropoietin with oral ferrous sulfate or intravenous ferric carboxymaltose. The primary endpoint was the hemoglobin value the day before surgery. RESULTS: One hundred patients were included in the analysis. The day before surgery, hemoglobin, increase in hemoglobin, and serum ferritin level were higher in the intravenous group. For the intravenous and oral groups, respectively, hemoglobin was as follows: median, 14.9 g/dl (interquartile range, 14.1 to 15.6) versus 13.9 g/dl (interquartile range, 13.2 to 15.1), group difference, 0.65 g/dl (95% CI, 0.1 to 1.2; P = 0.017); increase in hemoglobin: 2.6 g/dl (interquartile range, 2.1 to 3.2) versus 1.9 g/dl (interquartile range, 1.4 to 2.5), group difference, 0.7 g/dl (95% CI, 0.3 to 1.1; P < 0.001); serum ferritin: 325 µg/l (interquartile range, 217 to 476) versus 64.5 µg/l (interquartile range, 44 to 107), group difference, 257 µg/l (95% CI, 199 to 315; P < 0.001). The percentage of patients with nausea, diarrhea, or constipation was higher in the oral group, 52% versus 2%; group difference, 50% (95% CI, 35 to 64%; P < 0.0001). CONCLUSIONS: After preoperative administration of erythropoietin, body iron stores and stimulation of the erythropoiesis were greater with intravenous ferric carboxymaltose than with oral ferrous sulfate supplementation.

BACKGROUND: Transperineal pudendal nerve block guided by nerve stimulator is used in pediatric anesthesia as an alternative to caudal analgesia in perineal surgery. The risk of rectal puncture or intravascular injection is inherent to this blinded technique. We described a new technique of transperineal pudendal nerve block, with ultrasound guidance, to improve safety of the technique. AIMS: The first goal of this study was to describe this new technique and to test its feasibility. The second objective was to evaluate intra operative effectiveness and postoperative pain control. METHODS: After parental and children consent, this prospective descriptive study included children aged 1-15 years, ASA status I-III, scheduled for general anesthesia associated with bilateral pudendal nerve block for an elective perineal surgery. After standardized general anesthesia, the anesthesiologist performed pudendal nerve block under ultrasound guidance with "out of plane" approach and evaluated the visualization of anatomical structures (ischial tuberosity, rectum, and pudendal artery), of the needle and of the local anesthetic spread. Pudendal nerve block failure was defined as an increase in mean arterial blood pressure or heart rate more than 20% compared to baseline values after surgical incision. In the postoperative period, the need for rescue analgesia was noted. RESULTS: During the study period, 120 blocks were performed in 60 patients, including 59 boys. Quality of the ultrasonographic image was good in 81% of blocks, with easy visualization of ischium and rectum in more than 95% of cases. Localization of the tip of the needle was possible for all pudendal nerve blocks, directly or indirectly. The spread of local anesthetic was seen in 79% of cases. The block was effective in 88% of cases. CONCLUSION: The new technique of ultrasound-guided pudendal nerve block, described in this study, seems to be easy to perform with a good success rate, and probably improves safety of the puncture and of the injection by real-time visualization of anatomical structures and local anesthetic spread.

BACKGROUND: There is no widely recognized effective technique to optimally reduce pain scores and prevent persistent postoperative pain after nephrectomy. We compared continuous surgical site analgesia (CSSA), epidural analgesia (EA), and a control group (patient-controlled analgesic morphine) in patients undergoing open nephrectomy. METHODS: Sixty consecutive patients were randomized to be part of EA, CSSA, or control groups postoperatively for 72 hours. All patients received patient-controlled analgesic morphine, if needed. Hyperalgesia was assessed on the first, second, and third postoperative days. Chronic pain characteristics and quality of life were analyzed at 1 and 3 months. The primary outcome was the pain score at 24 hours. Secondary outcomes were morphine consumption, postoperative rehabilitation, hyperalgesia, chronic pain incidence, and quality-of-life parameters. RESULTS: At 24 hours, mean ± standard deviation pain values at rest (2.4 ± 1.7, 2.2 ± 1.2, and 4.2 ± 1.2, respectively, in EA, CSSA, and control groups, P <.001) and during coughing was lower in the EA and CSSA groups. Total morphine consumption was higher in the control group. Rehabilitation parameters improved sooner in the EA and CSSA groups. Median values of area of hyperalgesia differed at 48 hours between the EA group and the control group (36.4 cm) and (52 cm) (P = .01) and at 72 hours among the EA group, CSSA group, and the control group (40 cm, 39.5 cm, and 59 cm, respectively; P = .002). CSSA reduced the severity of pain and hyperalgesia at 1 month and optimized quality of life 3 months after surgery (role physical scores, P = .005). CONCLUSIONS: CSSA and EA significantly improve postoperative analgesia, reduce postoperative morphine consumption, area of wound hyperalgesia, and accelerate patient rehabilitation after open nephrectomy. CSSA significantly reduces the severity of residual pain 1 month after surgery and optimizes quality-of-life parameters 3 months after surgery.

BACKGROUND: Preoperative anxiety management receives special attention in pediatric anesthesia. Different pharmacological and nonpharmacological techniques can be employed. This study was designed to assess three different strategies for childhood preoperative anxiolysis: midazolam premedication, midazolam in combination with portable Digital Video-Disk player, or video distraction strategy alone. METHODS: In this prospective randomized study, children aged 2-12 years were assigned to one of the three study groups. The primary outcome was a change in preoperative children's anxiety, from baseline (before transfer to the preanesthetic holding area) to separation from parents, assessed by the Modified Yale Preoperative Anxiety Scale (mYPAS) and the Visual Analog Anxiety Scale (VAS-Anxiety). Delirium emergence, postoperative pain, and parental satisfaction were also collected. RESULTS: One hundred and thirty-five patients were enrolled. The three preventive strategies allowed control of preoperative distress. Within the three study groups, no significant change was objectified in the anxiety level from baseline to separation from parents (mean change in mYPAS midazolam group: 2.4 95% CI [-1.7 to 6.3]; midazolam+Digital Video-Disk group: -1.0 95% CI [-5.9 to 3]; and Digital Video-Disk group: 1.4 95% CI [-4 to 6.7]). Comparison of change in preoperative children's anxiety between the groups did not show any difference. Emergence delirium, postoperative pain scores, and analgesic consumption were similar between the groups and parents' satisfaction was excellent. CONCLUSION: Both pharmacological premedication and video distraction are effective strategies for controlling preoperative childhood anxiety. The combination of midazolam and Digital Video-Disk player was not better than either alone.

BACKGROUND: In this study, we sought to determine whether a simplified ultrasound measurement of the largest transverse diameter, using a standard ultrasound machine, could be used to diagnose postoperative urinary retention (POUR). This method may replace expensive bladder volume measuring devices or a more complex ultrasound procedure (involving the measurement of 3 bladder diameters). METHODS: Patients at risk of POUR if unable to void after orthopedic surgery were evaluated in the postanesthesia care unit before discharge. Bladder diameter was first measured using a portable ultrasound device (Vscan®; GE Healthcare, Wauwatosa, WI). An automated evaluation of bladder volume was then performed (Bladderscan® BVI 3000; Diagnostic Ultrasound, Redmond, WA). Finally, when a bladder catheterization was performed, the actual urinary volume was measured. The main outcome was a bladder volume ≥600 mL as measured using the automated ultrasound scanner (Bladderscan BVI 3000) or by catheterization. Correlations between bladder volumes and diameter were studied and receiver operating characteristic curves were constructed to determine the performance in predicting a bladder volume ≥600 mL. A "gray zone" approach was developed because a single cutoff value may not always be clinically significant. RESULTS: One hundred patients were included and underwent a Bladderscan measurement. Urinary volume after catheterization was obtained in 49 patients. A significant correlation was found between the largest transverse diameter and urinary volumes assessed by the 2 methods (Bladderscan and catheterization). Pearson correlation coefficients were r = 0.80 (95% confidence interval [CI], 0.72-0.86; P < 0.001) and r = 0.79 (95% CI, 0.65-0.88; P < 0.001), respectively. The area under the receiver operating characteristic curves for the prediction of a bladder volume ≥600 mL were 0.94 (95% CI, 0.88-0.98) and 0.91 (95% CI, 0.79-0.97), respectively, for urinary volumes assessed by Bladderscan and catheterization. The optimal cutoff value was 9.7 cm for both methods. The gray zone was narrow, ranging from 9.7 to 10.7 cm thus limiting inconclusive measurements. CONCLUSIONS: A simple ultrasound measurement of the largest transverse bladder diameter seemed to be helpful to exclude or confirm POUR.

BACKGROUND: The authors investigated the efficacy of bilateral suprazygomatic maxillary nerve block (SMB) for postoperative pain relief in infants undergoing cleft palate repair. METHODS: In this prospective, double-blind, single-site, randomized, and parallel-arm controlled trial, 60 children were assigned to undergo bilateral SMB with general anesthesia with either 0.15 ml/kg of 0.2% ropivacaine (Ropi group) or 0.15 ml/kg of isotonic saline (Saline group) on each side. The primary endpoint was total postoperative morphine consumption at 48 h. Pain scores and respiratory- and SMB-related complications were noted. RESULTS: The overall dose of intravenous morphine after 48 h (mean [95% CI]) was lower in the Ropi group compared with that in the Saline group (104.3 [68.9 to 139.6] vs. 205.2 [130.7 to 279.7] µg/kg; P = 0.033). Continuous morphine infusion was less frequent in the Ropi group compared with that in the Saline group (1 patient [3.6%] vs. 9 patients [31%]; P = 0.006). Three patients in the Saline group had an episode of oxygen desaturation requiring oxygen therapy. There were no technical failures or immediate complications of the SMB. Intraoperative hemodynamic parameters, doses of sufentanil, pain scores, and postoperative hydroxyzine requirements were not different between the two groups. CONCLUSION: Bilateral SMB is an easy regional anesthesia technique that reduces total morphine consumption at 48 h after cleft palate repair in children and the use of continuous infusion of morphine and may decrease postoperative respiratory complications.

BACKGROUND: Regional anaesthesic techniques are commonly used for the management of pain following lower abdominal surgery in children. The transversus abdominis plane (TAP) block has shown promise for perioperative analgesia, but data on the optimal dose regimen are limited. OBJECTIVE: To evaluate the optimal dose of levobupivacaine for successful ultrasound-guided TAP block in children. DESIGN: A dose finding prospective study using Dixon's up-and-down sequential method. SETTING: University Hospital Paediatric Anaesthesia Unit. PATIENTS: Twenty-seven consecutive children aged 1 to 5 years scheduled for day-case elective herniorrhaphy. INTERVENTION: After standardised induction of general anaesthesia, ultrasound-guided TAP block was performed with a fixed volume of 0.2 âml âkg(-1) of levobupivacaine solution. The dose of levobupivacaine was determined by Dixon's up-and-down method starting from 0.5 âmg âkg(-1)with an interval of 0.1âmg ââkg(-1). Block failure was defined as a 20% increase in heart rate or mean arterial pressure from baseline. Rescue analgesia consisted of intravenous remifentanil infusion during surgery and intravenous nalbuphine in the postanaesthetic care unit (PACU). Patients were assessed using the FLACC (face, legs, activity, cry and consolability) pain scale, the rescue analgesic consumption in the PACU and day-case unit and the postoperative pain measure for parents score at home. MAIN OUTCOME MEASURES: The mean effective dose of levobupivacaine resulting in an effective TAP block in 50% of cases (ED50) obtained by using Dixon's up-and-down sequential method. The ED50 and ED95 were further estimated by bootstrapping. RESULTS: The ED50 according to the up-and-down staircase method was 0.22â mgâ âkg(-1) [95% confidence interval (CI) 0.19 to 0.25]. Bootstrap replicates of the original dataset resulted in ED50 and ED95 estimates of 0.16â mg â âkg(-1) (95% CI 0.11 to 0.24) and 0.43âmg âkg(-1)(95% CI 0.30 to 0.57), respectively. CONCLUSION: As part of a multimodal analgesia strategy, ultrasound-guided TAP block with 0.2 âml âkg(-1)of 0.2% levobupivacaine provides successful peroperative analgesia in 95% of children who underwent herniorrhaphy.

BACKGROUND: Hallux valgus surgery is associated with moderate to severe postoperative pain. We hypothesized that a plantar compartment block may be a good technique for postoperative analgesia. We describe an anatomic approach to ultrasound-guided plantar compartment block and assess the clinical efficacy of the block for outpatient surgery. METHODS: The anatomic study was aimed to describe the plantar compartment, using both dissection methods and imaging, and to define a volume of local anesthetic. Patients scheduled for hallux valgus surgery with a popliteal sciatic nerve block, and combined plantar compartment and peroneal blocks were included in the clinical study. Data on attaining the criteria for rapid exit from the outpatient center, duration of sensory and analgesic block, visual analog scale (VAS) values for postoperative pain at rest and during movement, and the consumption of morphine as rescue analgesia were recorded. RESULTS: Plane-by-plane dissections and cross-sections were done in five cadaveric lower limbs. The medial calcaneal nerve divides into medial plantar and lateral plantar nerves in the upper part of the plantar compartment. These nerves were surrounded by 5 mL of colored gelatin, and 10 mL of injectates dye spread to the medial calcaneal branches. Thirty patients (26 women) were included in the clinical study. There were no failures of surgical block. Ninety per cent of patients successfully passed functional testing for ambulatory exit from the center within 5 hours (25th-75th centiles, 3.8-5.5 hours). The median duration of plantar compartment sensory block was 17.3 hours (10.5-21.5 hours), and the first request for rescue analgesic was 11.75 hours (10.5-23 hours) after surgery. The median VAS score for maximum pain reported within the 48-hour period was 2 (1-6). Twelve patients received 2.5 mg (0-5 mg) of morphine on day 1. Patients were highly satisfied and no adverse events were noted. CONCLUSIONS: This anatomic description of the ultrasound-guided plantar compartment block reported the injection area to target the medial and lateral plantar nerves with 5 mL of local anesthetic. Normal walking without assistance is attained rapidly with this regional anesthesia technique, and the time to request postoperative analgesia after hallux valgus surgery is long. TRIAL REGISTRATION NUMBER: NCT03815422.
RESUMEN
BACKGROUND: Sedation of ventilated critically ill trauma patients requires high doses of opioids and hypnotics. We aimed to compare the consumption of opioids and hypnotics, and patient outcomes using sedation with or without continuous regional analgesia (CRA). METHODS: Multiple trauma-ventilated patients were included. The patients were randomized to receive an intravenous analgesia (control group) or an addition of CRA within 24h of admission. A traumatic brain injury (TBI) patients group was analyzed. The primary endpoint was the cumulative consumption of sufentanil at 2 days of admission. Secondary endpoints were cumulative and daily consumption of sufentanil and midazolam, duration of mechanical ventilation, intensive care unit (ICU) stay, and safety of CRA management. RESULTS: Seventy six patients were analyzed: 40 (67.5% males) in the control group and 36 (72% males) in the CRA group, respectively. The median [IQR] Injury Severity Score was 30.5 [23.5-38.5] and 26.0 [22.0-41.0]. The consumption of sufentanil at 48h was 725 [465-960] µg/48h versus 670 [510-940] µg/48h (p = 0.16). Daily consumption did not differ between the groups except on day 1 when consumption of sufentanil was 360 [270-480] µg vs. 480 [352-535] µg (p = 0.03). Consumptions of midazolam did not differ between the groups. No difference was noted between the groups according to the secondary endpoints. CONCLUSIONS: CRA does not decrease significantly sufentanil and midazolam consumption within the first 5 days after ICU admission in multiple trauma-ventilated patients. The use of peripheral nerve blocks in heavily sedated and ventilated trauma patients in the ICU seems safe.
