A Retrospective Study: Multimodal Analgesia Quality Measure Implementation and Patient Outcome Assessment.

Current research has demonstrated that nonopioid multimodal analgesia decreases perioperative opioid consumption, postoperative nausea and vomiting (PONV), and pain scores. However, no research has been conducted to examine the patient outcomes of Merit-based Incentive Payment System (MIPS) 477. This study evaluates those outcomes following implementation of MIPS 477. The medical records of 400 adult patients who underwent elective and urgent laparoscopic gynecological procedures at a facility in the Mid-Atlantic region were reviewed. Data collection included patient characteristics, analgesics administered, pain scores at postanesthesia care unit (PACU) arrival and discharge, and antiemetic administration in PACU. This study's primary outcomes were postoperative pain scores, total intraoperative and postoperative opioid consumption, and PONV. Twenty-nine patients (7.8%) met the criteria as a control group, and 341 patients (92.2%) met the criteria as a treatment group. Pain scores were higher upon PACU arrival among the control group (P = .001). The total intraoperative morphine milligram equivalents (MMEs) administered was less among the treatment group (P = .04). The treatment group had reduced total intraoperative MMEs and pain scores at PACU arrival. However, there was no statistical significance in PACU discharge pain score, total PACU MMEs, and PONV in both groups.

ASSESSMENT OF THE EFFICIENCY OF ANALGETIC ACTION OF LAPAROSCOPICALLY ASSISTED TAP BLOCK AS A COMPONENT OF PERIOPERATIVE MULTIMODAL ANALGESIA PLAN IN OBESE PATIENTS UNDERGOING METABOLIC SURGERY.

OBJECTIVE: The aim: To assess the effectiveness and feasibility of laparoscopically assisted TAP block utilization in the system of multimodal analgesia by comparing the severity of pain and associated postoperative recovery indicators in obese patients after laparoscopic sleeve gastrectomy. PATIENTS AND METHODS: Materials and methods: The retrospective study included 39 patients, who underwent metabolic surgery from 2013-2022. All patients were divided into 2 groups depending on the chosen perioperative analgesia protocol. Group 1 included 19 patients who prior to skin incision a local infiltration of the trocar puncture areas of the abdominal wall. Group 2 included 20 patients, whom in addition to the above-described anaesthesia procedure after completion of the main stage of surgery, a laparoscopically assisted bilateral subcostal TAP block was additionally performed. RESULTS: Results: The need to use opioid analgesics in the rescue analgesia mode arose in 17.6% (3/17) of patients of the first group, and 5% (1/20) of patients in the second group Average duration of postoperative hospitalization in group 1 was 7.2±1.1 days, and in group 2 it was 6.2±1.4 days (P <0.05). CONCLUSION: Conclusions: Subcostal TAP block in obese patients is a safe and effective method of regional anaesthesia. Further study of this option of regional anaesthesia is required in order to be able to form clearer recommendations for its routine use in clinical practice.

Clinical and cost-effectiveness of paramedic administered fascia iliaca compartment block for emergency hip fracture (RAPID 2)-protocol for an individually randomised parallel-group trial.

BACKGROUND: Approximately 75,000 people fracture a hip each year in the UK. This painful injury can be devastating-with a high associated mortality rate-and survivors likely to be more dependent and less mobile. Pain relief at the scene of injury is known to be inadequate. Intravenous morphine is usually given by paramedics, but opioids are less effective for dynamic pain and can cause serious side effects, including nausea, constipation, delirium and respiratory depression. These may delay surgery, require further treatment and worsen patient outcomes. We completed a feasibility study of paramedic-provided fascia iliaca compartment block (FICB), testing the intervention, trial methods and data collection. The study (RAPID) demonstrated that a full trial was feasible. In this subsequent study, we aim to test safety, clinical and cost-effectiveness of paramedic-provided FICB as pain relief to patients with suspected hip fracture in the prehospital environment. METHODS: We will conduct a pragmatic multi-centre individually randomised parallel-group trial, with a 1:1 allocation between usual care (control) and FICB (intervention). Hospital clinicians in five sites (paired ambulance services and receiving hospitals) in England and Wales will train 220 paramedics to administer FICB. The primary outcome is change in pain score from pre-randomisation to arrival at the emergency department. One thousand four hundred patients are required to find a clinically important difference between trial arms in the primary outcome (standardised statistical effect ~ 0.2; 90% power, 5% significance). We will use NHS Digital (England) and the SAIL (Secure Anonymised Information Linkage) databank (Wales) to follow up patient outcomes using routine anonymised linked data in an efficient study design, and questionnaires to capture patient-reported outcomes at 1 and 4 months. Secondary outcomes include mortality, length of hospital stay, job cycle time, prehospital medications including morphine, presence of hip fracture, satisfaction, mobility, and NHS costs. We will assess safety by monitoring serious adverse events (SAEs). DISCUSSION: The trial will help to determine whether paramedic administered FICB is a safe, clinically and cost-effective treatment for suspected hip fracture in the pre-hospital setting. Impact will be shown if and when clinical guidelines either recommend or reject the use of FICB in routine practice in this context. TRIAL REGISTRATION: ISRCTN15831813 .

Local infiltration analgesia versus peripheral nerve block anaesthesia in total knee arthroplasty: a pharmaco-economic comparison.

BACKGROUND: A superior analgesic method in perioperative pain-management of patients receiving total knee arthroplasty is the subject of controversial debate. Although higher cost-efficiency is claimed for the local infiltration analgesia (LIA), there is a lack of data on its costs compared to peripheral nerve block anaesthesia (PNBA). The goal of this study was to investigate the differences in immediate perioperative costs between the LIA and PNBA in treatment of patients receiving total knee arthroplasty. METHODS: The comparison was conducted based on a randomized controlled clinical trial examining 40 patients with elective, primary total knee arthroplasty (TKA, 20 patients with LIA and 20 patients with PNBA). The analysis included surgical case costs, anaesthesiological case costs, material, costs of postoperative opioid requirements and catheter review visits for patients receiving PNBA. RESULTS: The overall mean costs for the LIA-group were 4328.72€ and 4368.12€ for the PNBA (p = 0.851). While there was no statistically significant difference in surgical case costs, the anaesthesiological costs were lower with the LIA procedure (1370.26€ vs. 1542.45€, p = 0.048). Material costs in the LIA group were 4.18€/patient and 94.64€/patient with the PNBA. Costs for postoperative opioid requirements showed no statistically significant difference between the two procedures. CONCLUSIONS: There is no relevant difference in immediate perioperative costs between LIA and PNBA. Shorter induction times lead to lower anaesthesiological case costs with the LIA. Overall economic aspects seem to play a less important role for determining an adequate procedure for perioperative pain management. TRIAL REGISTRATION: The study was approved by the ethics-review-board of Charité Hospital Berlin (Ethikausschuss 4, Charité - Universitätsmedizin Berlin, on 16th February 2017) and registered with data safety authorities. Study patients provided written informed consent to participate in the trial. Study registry: ClinicalTrials.gov, NCT03114306 .

ASSESSMENT OF THE EFFICIENCY OF ANALGETIC ACTION OF ULTRASOUND-GUIDED FICB AS A COMPONENT OF PERIOPERATIVE MULTIMODAL ANALGESIA IN ERAS- STRUCTURE IN OBESE PATIENTS UNDERGOING TOTAL HIP REPLACEMENT.

OBJECTIVE: The aim: To compare the efficiency of analgetic action of Ultrasound-guided FICB and prolonged EA as the components of perioperative multimodal analgesia in ERAS-structure in obese patients undergoing THR. PATIENTS AND METHODS: Materials and methods: The retrospective study included 80 patients with obesity, who underwent elective anterolateral THR under conditions of low-flow inhalation anesthesia with sevoflurane in combination with PEA (n1=38) or with FICB (n2=42). Primary endpoints: VAS pain level during the first postoperative day. RESULTS: Results: Static and dynamic VAS pain scores were similar in both groups during the first 6 hours. Since the 8th postoperative hour, there was a statistically significant increase in both static and dynamic VAS pain scores in the FICB group. A significant difference in static and dynamic VAS pain scores was obtained with a trend toward an increase in the PEA group within 48 hours (p < 0.05). CONCLUSION: Conclusions: USG- FICB is an effective, practically feasible, minimally invasive and safe regional method for eleclive anterior-lateral THR and can be an alternative to PEA in obese patients.

Novel Analgesic Index for Postoperative Pain Assessment Based on a Photoplethysmographic Spectrogram and Convolutional Neural Network: Observational Study.

BACKGROUND: Although commercially available analgesic indices based on biosignal processing have been used to quantify nociception during general anesthesia, their performance is low in conscious patients. Therefore, there is a need to develop a new analgesic index with improved performance to quantify postoperative pain in conscious patients. OBJECTIVE: This study aimed to develop a new analgesic index using photoplethysmogram (PPG) spectrograms and a convolutional neural network (CNN) to objectively assess pain in conscious patients. METHODS: PPGs were obtained from a group of surgical patients for 6 minutes both in the absence (preoperatively) and in the presence (postoperatively) of pain. Then, the PPG data of the latter 5 minutes were used for analysis. Based on the PPGs and a CNN, we developed a spectrogram-CNN index for pain assessment. The area under the curve (AUC) of the receiver-operating characteristic curve was measured to evaluate the performance of the 2 indices. RESULTS: PPGs from 100 patients were used to develop the spectrogram-CNN index. When there was pain, the mean (95% CI) spectrogram-CNN index value increased significantly-baseline: 28.5 (24.2-30.7) versus recovery area: 65.7 (60.5-68.3); P<.01. The AUC and balanced accuracy were 0.76 and 71.4%, respectively. The spectrogram-CNN index cutoff value for detecting pain was 48, with a sensitivity of 68.3% and specificity of 73.8%. CONCLUSIONS: Although there were limitations to the study design, we confirmed that the spectrogram-CNN index can efficiently detect postoperative pain in conscious patients. Further studies are required to assess the spectrogram-CNN index's feasibility and prevent overfitting to various populations, including patients under general anesthesia.

Assessment of Hypnosis Knowledge Among Dentists: A Cross-Sectional Study

ABSTRACT Objective: To assess the attitudes, experiences, training levels, and interest in future education regarding the use of hypnosis by dentists working in Dental Clinic of Monastir, Tunisia. Material and Methods: A cross-sectional study was conducted among 330 dentists working in Dental Clinic of Monastir in November 2019. Students, internship, residents, and professors were randomly selected. This was a survey with a structured questionnaire mailed to all dentists. The questionnaire was pre-fabricated, simple, and close-ended. Data were analyzed using SPSS 24.0 statistical software. Results: A total of 202 dentists respond to this survey. 54% of the participants were interns with a female predominance (66.5%). Findings revealed that beliefs toward hypnosis in the sample were generally positive. Using a visual analogue scale, dentists reported having moderate acknowledge in hypnosis (3.4). 60% of the participants in our study consider that hypnosis is useful in dentistry and, more particularly, in pediatric dentistry. 78.2% of respondents want to follow training courses in hypnosis. Conclusion: Our survey highlights the weak knowledge of participants in hypnosis and reveals certain misconceptions about this procedure. More efforts are required to better educate dentists about hypnosis's benefits in their practice.

Assessment of Patient's Satisfaction and Associated Factors regarding Postoperative Pain Management at the University of Gondar Compressive Specialized Hospital, Northwest Ethiopia.

Objective: We aimed to assess the level of patient's satisfaction and associated factors regarding postoperative pain management. Methods: An institution-based cross-sectional study was conducted from April to May 2018 at the University of Gondar, and comprehensive specialized hospital data were collected through semistructured questionnaire and chart review. Level of satisfaction was measured using five-point Likert scale. Statistical analysis was done using SPSS software version 23. Both bivariable and multivariable logistic regression analyses were done. Variables of P value ≤0.2 in the bivariable analysis were a candidate for multivariable logistic regression. A P value ≤0.05 was considered as significantly associated with patient's level of satisfaction at 95% CI. Results: A total of 418 patients were included in this study with a response rate of 98.58%. The overall proportion of patients who were satisfied with pain management services was 72.2% (95% CI: 67.7-76.6). ASA1 (AOR = 3.55: 95% CI = 1.20-10.55) and ASA2 patients (AOR = 3.72: 95% CI = 1.04-13.28), absence of postoperative pain (AOR = 1.86: 95% CI = 1.02-3.39), peripheral nerve block done (AOR = 9.14: 95% CI = 3.93 20.86), received analgesic before request (AOR = 6.90: 95% CI = 3.72-12.83), and received systemic analgesics (AOR = 6.10: 95% CI = 1.17-33.91) were significantly associated with the level of satisfaction. Conclusion: The level of patient satisfaction with postoperative pain management was considerably low. Hence, it is vital to implement time-interval pain assessment method during the first 24 hours of postoperative period and treat accordingly based on the WHO pain ladder. Moreover, we suggested that all patients who underwent major surgery should receive peripheral nerve block as part of multimodal analgesia to decrease the incidence and severity of post op pain.

"Outpatient"-Same-calendar-day Discharge Hip and Knee Arthroplasty.

As the length of stay for hip and knee arthroplasty has decreased over the years, "outpatient," or same-calendar-day discharge has become increasingly common. Outpatient arthroplasty offers several possible benefits over traditional inpatient arthroplasty, including potential for cost reductions, faster rehabilitation, improved patient satisfaction, and reduced reliance on hospital resources. Despite these possible benefits, concerns remain over feasibility and patient safety. To date, multiple studies have demonstrated that, for select patients, "outpatient" hip and knee arthroplasty can be safe and effective and yield complication and readmission rates similar to inpatient procedures at potentially significant cost savings. Successful outpatient pathways have emphasized careful patient selection, detailed patient education, enlistment of strong social support, utilization of multimodal analgesia and strong "episode ownership," and involvement on behalf of the surgical team. As outpatient hip and knee arthroplasty becomes increasingly common, continued investigation into all aspects of the surgical episode is warranted.

Intrathecal hydromorphone as an analgesia option for gynecology patients.

Enhanced recovery after surgery (ERAS) is a multimodal perioperative strategy originally developed to attenuate the postsurgical stress response in patients after colorectal surgery. Patients undergoing gynecologic surgery who had ERAS had significantly shorter hospital length of stay, reduced hospital-related costs, and acceptable pain management with reduced opioid use, without compromising patient satisfaction. Intrathecal hydromorphone is an effective alternative ERAS protocol analgesia for these patients and will not compromise patient outcomes or healthcare costs.

Pain assessment of a new bloodletting device: A study protocol for a randomized, controlled, double-blind, matched-paired clinical trial.

BACKGROUND: The bloodletting device has been used by many institutions for about 100 years. Many patients feel fear from the pain caused by applying the bloodletting device for treatment. We used bloodletting device using the principle of "prestimulation neurodisturbance," which can mask the subject undetectable for pain. In this study, we will investigate pain of bloodletting device during blood collection and will identify the safety of the device. METHODS: This study will be a randomized, controlled, double-blind, and matched-paired-designed clinical trial. Four groups, RTLC, LTRC, RCLT, and LCRT (T = test device, C = control device, L = left, R = right), will be randomly allocated. Total duration of the clinical trial will be 3 months. The subjects will be performed from 1 to 3 times only on the day of the procedure. The primary outcomes will be measured using pain visual analog scale score and the secondary outcomes will include verbal rating scale and the time at which the pain disappears after blood collection (second), the total number of "nonbleeding" cases and subjects, the number of "blood collection failure" and subjects, the presence of "delayed hemostasis," and the number of subjects. Repeated-measure analysis will be used to measure primary efficacy based on full analysis set. DISCUSSION: This study has limited inclusion and exclusion criteria and a well-controlled intervention, and it will be the first randomized controlled trial to investigate pain of bloodletting device using the principle of "prestimulation neurodisturbance." This study provides insights into the underlying mechanisms of the pain-reducing effect of the developed bloodletting device and will lay the groundwork for further studies.

Rapid recovery following hip and knee arthroplasty using local infiltration analgesia: length of stay, rehabilitation protocol and cost savings.

BACKGROUND: We implemented local infiltration analgesia (LIA) as a technique of providing post-operative pain management and early mobilization after arthroplasty surgery and have progressively found patients able to go home earlier. This study compares the national data on hip and knee arthroplasty provided by the Royal Australasian College of Surgeons and Medibank Private with our outcomes using LIA and rapid recovery. METHODS: Prospective study of one surgeon including 200 knees, and 165 hips in the two years till June 2016. Variables included in comparison to the two groups were: length of stay, percentage of patients transferred to rehabilitation or intensive care unit (ICU), readmitted within 30 days and average separation cost. RESULTS: Hip replacement median length of stay in our series was two nights versus five nights, inpatient rehabilitation 7% versus 36%, ICU admission zero versus 4%, and readmissions 3.9% versus 6.0%, the average hospital separation cost in our series was $17 813 versus $26 734. Knee replacement median length of stay in our study was one night versus five nights, ICU 0.5% versus 3%, rehabilitation 4.5% versus 43%, and readmission 6% versus 7%, the average hospital separation cost in our group was $16 437 versus $27 505. CONCLUSION: The comprehensive approach of LIA and rapid recovery enables patients to have shorter hospitalization, lower rehabilitation incidence and a resultant reduction in health expenditure.

Practices related to assessment of sedation, analgesia and delirium among critical care pediatricians in Brazil.

OBJECTIVE: To understand the use of tools, protocols and comfort measures related to sedation/analgesia, and to screen the occurrence of delirium in pediatric intensive care units. METHODS: A survey with 14 questions was distributed by e-mail to Brazilian critical care pediatricians. Eight questions addressed physician and hospital demographics, and six inquired practices to assess sedation, analgesia, and delirium in pediatric intensive care units. RESULTS: Of 373 questionnaires sent, 61 were answered (16.3%). The majority of physicians were practicing in the Southeast region (57.2%). Of these, 46.5% worked at public hospitals, 28.6% of which under direct state administration. Of respondents, 57.1% used formal protocols for sedation and analgesia, and the Ramsay scale was the most frequently employed (52.5%). Delirium screening scores were not used by 48.2% of physicians. The Cornell Assessment of Pediatric Delirium was the score most often used (23.2%). The majority (85.7%) of physicians did not practice daily sedation interruption, and only 23.2% used non-pharmacological measures for patient comfort frequently, with varied participation of parents in the process. CONCLUSION: This study highlights the heterogeneity of practices for assessment of sedation/analgesia and lack of detection of delirium among critical care pediatricians in Brazil.

Evidence-based clinical practice guidelines for the management of sedoanalgesia and delirium in critically ill adult patients. / Guías de práctica clínica basadas en la evidencia para el manejo de la sedoanalgesia y delirium en el paciente adulto críticamente enfermo.

Given the importance of the management of sedation, analgesia and delirium in Intensive Care Units, and in order to update the previously published guidelines, a new clinical practice guide is presented, addressing the most relevant management and intervention aspects based on the recent literature. A group of 24 intensivists from 9 countries of the Pan-American and Iberian Federation of Societies of Critical Medicine and Intensive Therapy met to develop the guidelines. Assessment of evidence quality and recommendations was made according to the Grading of Recommendations Assessment, Development and Evaluation Working Group. A systematic search of the literature was carried out using MEDLINE, Cochrane Library databases such as the Cochrane Database of Systematic Reviews and the Cochrane Central Register of Controlled Trials (CENTRAL), the Database of Abstracts of Reviews of Effects, the National Health Service Economic Evaluation Database and the database of Latin American and Caribbean Literature in Health Sciences (LILACS). A total of 438 references were selected. After consensus, 47 strong recommendations with high and moderate quality evidence, 14 conditional recommendations with moderate quality evidence, and 65 conditional recommendations with low quality evidence were established. Finally, the importance of initial and multimodal pain management was underscored. Emphasis was placed on decreasing sedation levels and the use of deep sedation only in specific cases. The evidence and recommendations for the use of drugs such as dexmedetomidine, remifentanil, ketamine and others were incremented.

A Multi-institutional Assessment of Multimodal Analgesia in Penile Implant Recipients Demonstrates Dramatic Reduction in Pain Scores and Narcotic Usage.

INTRODUCTION: Despite the pain associated with inflatable penile prosthesis (IPP) implantation, there has been a lack of standardized, nonopioid pain control regimens described to date. AIM: To assess the effectiveness of a multimodal analgesic regimen in patients undergoing implantation of an IPP compared with patients treated with an opioid-only regimen. METHODS: A large, multicenter patient cohort undergoing IPP implantation whose pain was managed using a multimodal analgesia (MMA) protocol (preoperative and postoperative acetaminophen, meloxicam orcelecoxib, and gabapentin and intraoperative dorsal and pudendal nerve blocks) was compared with a matched cohort of patients managed via an opioid-only protocol. Both groups were compared with respect to visual analog score (VAS) and opioid usage (total morphine equivalents [TME]) in the post-anesthesia care unit (PACU), postoperative day 0 (POD0) and postoperative day 1 (POD1), and in the immediate postdischarge period. Narcotic usage on discharge and follow-up were assessed and compared. MAIN OUTCOME MEASURE: Postoperative pain scores and narcotic usage are the main outcome measures. RESULTS: 203 patients were eligible for final analysis: 103 (50.7%) patients receiving MMA medication and 100 (49.3%) patients receiving opioids only. The VAS was significantly lower in the multimodal group in PACU (median 0.0 vs 2.0, P = .001), POD0 (median 3.0 vs 4.0, P = .001), and POD1 (median 3.0 vs 4.3, P = .04). Patients in the multimodal group also used fewer narcotics in PACU (median 0.0 vs 4.0 TME, P = .001), POD0 (median 7.5 vs 12.5 TME, P < .001), and POD1 (median 7.5 vs 13.5 TME, P = .01). Despite being discharged with fewer narcotics (median 20.0 vs 30.0 tablets, P < .001), a smaller proportion of patients in the MMA cohort required narcotic refills (10.7% vs 28.0%, P = .001). There were no narcotic- or MMA medication-related side effects in the entire cohort. CLINICAL IMPLICATIONS: MMA confers significant improvement in pain management while also providing a significant reduction in narcotic usage in patients undergoing implantation of IPP. STRENGTH & LIMITATIONS: This is the 1st large multi-institutional assessment of a multimodal analgesic regimen in urologic prosthetic surgery. The analgesic regimen targets several pain pathways that provide excellent pain control throughout the recovery process. Limitations include retrospective design and lack of standardization of the nonsteroidal anti-inflammatory drug type within the multimodal analgesic regimen. CONCLUSION: The use of a MMA protocol significantly reduces postoperative pain measures in penile implant recipients and further reduces both inpatient and outpatient narcotic usage without any discernable side effects.

Conclusão Este estudo destaca a heterogeneidade nas práticas de avaliação da sedação/analgesia e insuficiência de rastreamento de delirium entre os intensivistas pediátricos brasileiros.

Pain management policies and reported practices in Swiss emergency departments: a national survey.

BACKGROUND: Acute pain is the most common complaint of patients presenting to emergency departments (EDs). Effective pain management is a core ED mission, but numerous studies have pointed to insufficient pain treatment or oligoanalgesia. According to a 1997 national survey in Swiss EDs, a validated pain scale was used in only 14%, an analgesia protocol in <5%, and 1.1% had a nurse-initiated pain protocol. Since then, numerous societal and health care factors have led to improved ED pain care. The aim of this study was to assess the state of ED pain management in Switzerland. METHODS: Hospital-based Swiss EDs open 24 hours a day and 7 days a week in 2013 were surveyed using a questionnaire. Data from 2013 were collected. Questions queried the pain management process by nurses and physicians in each ED. RESULTS: The response rate was 115 of 137 eligible EDs (84%). Pain intensity was assessed with a validated instrument in 71% of waiting rooms and in 99% of treatment areas. A nurse-initiated analgesia protocol was available in 56% of waiting rooms and in 70% of treatment areas. Physician pain protocols were available in 75%, and analgesia-sedation protocols in 51%. CONCLUSION: The pain management processes in Swiss EDs have improved over the last 17 years, and are now equivalent to other western countries. Our study did not, however, assess if these improvements resulted in better analgesia at the bedside, an important topic that will require further study.

Sensory assessment and block duration of transmuscular quadratus lumborum block at L2 versus L4 in volunteers: a randomized controlled trial.

BACKGROUND: The efficacy of an ultrasound guided transmuscular quadratus lumborum block (QLB) for perioperative analgesia of the upper and lower abdomen remain debatable. The purpose of this study was to compare the cutaneous sensory blocked area (CSBA) between QLB blocks performed at the L2 vs. L4 levels. METHODS: Twenty-two healthy volunteers were randomized 1:1 to receive an ultrasound guided right transmuscular QLB at the L2 level (group QL2) or L4 level (group QL4). A cold stimulus was applied for testing of the CSBA at 30 minutes after the blockade was performed. The CSBA was mapped and then calculated. Three hours after the QLB, a cold stimulus was applied once every hour until sensation returned normal and the effective block duration for each volunteer was determined and recorded. RESULTS: The maximum cephalad dermatome level reached was T7 in group QL2 vs. T11 in group QL4, respectively. Caudally, both groups reached the L2 dermatome level. The QL2 block primarily affected dermatomes T9 to L1, while the QL4 block affected T11 to L1. The total CSBA was larger in QL2 group than that in QL4 group (748 [171] cm2 vs. 501 [186] cm2, P=0.004). The effective duration of the QLB was significantly longer in group QL2 than in group QL4 (18.5 [2.0]h vs. 14.1 [4.7]h, P=0.012). The number of affected dermatomes assessed by cold test was significantly larger for the volunteers in groups QL2 (4.6 [0.81] vs. 2.1 [0.30], P<0.001). CONCLUSIONS: Ultrasound guided transmuscular QLB injection of 0.375% 20 mL ropivacaine at the L2 level produced a widespread cutaneous sensory blockade and a prolonged sensory block to cold sensation compared with the L4 level.

[Analgesia Nociception Index: assessment of acute postoperative pain]. / Índice de Analgesia/Nocicepção: avaliação da dor aguda pós­operatória.

BACKGROUND AND OBJECTIVES: Patient self-rating based scales such as Numerical Rating Scale, Visual Analog Scale that is used for postoperative pain assessment may be problematic in geriatric or critically ill patients with communication problems. A method capable of the assessment of pain in objective manner has been searched for years. Analgesia nociception index, which is based on electrocardiographic data reflecting parasympathetic activity, has been proposed for this. In this study we aimed to investigate the effectiveness of analgesia nociception index as a tool for acute postoperative pain assessment. Our hypothesis was that analgesia nociception index may have good correlation with Numerical Rating Scale values. METHODS: A total of 120 patients of American Society of Anesthesiologists (ASA) physical status I and II undergoing any surgical procedure under halogenated-based anesthesia with fentanyl or remifentanil were enrolled for the study. At the 15th minute of arrival to the Postoperative Care Unit the patients' pain was rated on a 0-10 point Numerical Rating Scale. The patients' heart rate, blood pressure, and analgesia nociception index scores were simultaneously measured at that time. The correlation between analgesia nociception index, heart rate, blood pressure and Numerical Rating Scale was examined. RESULTS: The study was completed with 107 patients, of which 46 were males (43%). Mean (SD) analgesia nociception index values were significantly higher in patients with initial Numerical Rating Scale ≤ 3, compared with Numerical Rating Scale> 3 (69.1 [13.4] vs. 58.1 [12.9] respectively, p <0.001). A significant negative linear relationship (r2=-0.312, p=0.001) was observed between analgesia nociception index and Numerical Rating Scale. CONCLUSION: Analgesia nociception index measurements at postoperative period after volatile agent and opioid-based anesthesia correlate well with subjective Numerical Rating Scale scores.

Analgesia Nociception Index: assessment of acute postoperative pain / Índice de Analgesia/Nocicepção: avaliação da dor aguda pós-operatória

Abstract Background and objectives Patient self-rating based scales such as Numerical Rating Scale, Visual Analog Scale that is used for postoperative pain assessment may be problematic in geriatric or critically ill patients with communication problems. A method capable of the assessment of pain in objective manner has been searched for years. Analgesia nociception index, which is based on electrocardiographic data reflecting parasympathetic activity, has been proposed for this. In this study we aimed to investigate the effectiveness of analgesia nociception index as a tool for acute postoperative pain assessment. Our hypothesis was that analgesia nociception index may have good correlation with Numerical Rating Scale values. Methods A total of 120 patients of American Society of Anesthesiologists (ASA) physical status I and II undergoing any surgical procedure under halogenated-based anesthesia with fentanyl or remifentanil were enrolled for the study. At the 15th minute of arrival to the Postoperative Care Unit the patients' pain was rated on a 0-10 point Numerical Rating Scale. The patients' heart rate, blood pressure, and analgesia nociception index scores were simultaneously measured at that time. The correlation between analgesia nociception index, heart rate, blood pressure and Numerical Rating Scale was examined. Results The study was completed with 107 patients, of which 46 were males (43%). Mean (SD) analgesia nociception index values were significantly higher in patients with initial Numerical Rating Scale ≤3, compared with Numerical Rating Scale >3 (69.1 [13.4] vs. 58.1 [12.9] respectively, p < 0.001). A significant negative linear relationship (r 2 = -0.312, p = 0.001) was observed between analgesia nociception index and Numerical Rating Scale. Conclusion Analgesia nociception index measurements at postoperative period after volatile agent and opioid-based anesthesia correlate well with subjective Numerical Rating Scale scores.

Resumo Justificativa e objetivo As escalas baseadas na autoavaliação de pacientes, como a Escala Visual Numérica e a Escala Visual Analógica, que são usadas para avaliar a dor pós-operatória podem ser problemáticas em pacientes geriátricos ou em estado crítico com problemas de comunicação. Portanto, um método capaz de avaliar a dor de maneira objetiva vem sendo pesquisado há anos. O índice de analgesia/nocicepção, baseado em dados eletrocardiográficos que refletem a atividade parassimpática, tem sido proposto para tal avaliação. Neste estudo, objetivamos investigar a eficácia do índice de analgesia/nocicepção como uma ferramenta para a avaliação da dor pós-operatória aguda. Nossa hipótese foi que o índice de analgesia/nocicepção pode ter boa correlação com os valores da Escala de Classificação Numérica. Métodos Um total de 120 pacientes com estado físico ASA I e II, submetidos a qualquer procedimento cirúrgico com o uso de anestésicos halogenados associados a fentanil ou remifentanil, foi incluído no estudo. No 15º minuto após a chegada à sala de recuperação pós-anestesia, a dor dos pacientes foi avaliada em uma escala numérica de 0-10 pontos. Os escores de frequência cardíaca, pressão arterial e o índice de analgesia/nocicepção dos pacientes foram medidos simultaneamente naquele momento. A correlação entre o índice de analgesia/nocicepção, frequência cardíaca, pressão arterial e a Escala Visual Numérica foi avaliada. Resultados O estudo foi concluído com 107 pacientes, dos quais 46 eram do sexo masculino (43%). Os valores da média (DP) do índice de analgesia/nocicepção foram significativamente maiores nos pacientes com valor inicial na Escala Visual Numérica ≤ 3, em comparação com valor na mesma escala > 3 (69,1 [13,4] vs. 58,1 [12,9], respectivamente, p < 0,001). Uma relação linear negativa significativa (r2 = -0,312, p = 0,001) foi observada entre o índice de analgesia/nocicepção e a Escala Visual Numérica. Conclusão As mensurações do índice de analgesia/nocicepção no pós-operatório após anestesia com agentes halogenados e opioides mostraram boa correlação com os escores subjetivos da Escala Visual Numérica.
