Application of wireless analgesic system in pain management after thoracoscopic lung resection: A retrospective cohort study with large sample / 中国胸心血管外科临床杂志

@#Objective     To investigate the effect of intravenous analgesia with a wireless or traditional analgesia pump system in thoracoscopic lung resection. Methods     Patients who used the patient-controlled intravenous analgesia after thoracoscopic lung resection between June 2016 and June 2021 were enrolled in the study. They were allocated into a wireless pump group (a ZigBee-based wireless analgesia pump system collecting data automatically) and a traditional analgesia pump group. Perioperative analgesia management followed the routine standard operation protocol of Shanghai Chest Hospital. The patients’ numeric rating scale (NRS) for pain and postoperative nausea and vomiting (PONV) scores were collected for analysis from the Anesthesia Information Record System. The incidence of postoperative analgesia insufficiency (defined as NRS≥4 points) within 48 h, the incidence of PONV within 24 h, and the 48 h completion rate of analgesia pump infusion were compared. Results    A total of 59 431 patients were collected, including 24 855 males and 34 576 females, 17 209 patients in the wireless pump group, and 42 222 patients in the traditional analgesia pump group. The incidence of analgesia insufficiency within 48 h after operation (3.75% vs. 4.98%, P=0.007), the incidence of PONV within 24 h after operation (13.60% vs. 16.70%, P=0.030) in the wireless pump group were lower than those in the traditional analgesia pump group. The 48 h completion rate of analgesia pump infusion in the wireless pump group was higher than that in the traditional analgesia pump group (83.40% vs. 71.90%, P<0.001). The wireless pump group could monitor the pressing times and use of the analgesia pump, while the traditional analgesia pump group could not record the relevant data. Conclusion    Compared with the traditional analgesia pump, the wireless analgesia management system may be convenient for timely, accurate and individualized management, and has good analgesic effect and low incidence of adverse reactions, and may be more suitable for perioperative analgesia management.

A holistic approach for postoperative pain management in children receiving dental treatment under general anesthesia: a randomized clinical trial / 口腔疾病防治

Objective @# To investigate the efficacy of a holistic approach for postoperative pain management in children receiving dental treatment under general anesthesia in day-surgery operating room. @*Methods@#A total of 120 children, aged 3-7 years, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, with ≥ 10 treated teeth, receiving comprehensive dental treatment under general anesthesia from January 2020 to August 2020 were enrolled in this trial and randomly allocated into the holistic approach group (group H, n=60) and including preemptive analgesia, instructions to parents for pain management and web-based assessment system (assessment pain by scanning the quick response code 4, 6, and 24 hours postoperatively) and the control group (group C, n=60) only scanning the quick response code. Pain, face, legs, activity, cry and consolability (FLACC) scale was used to assess the level of pain 2 h postoperatively and the parents postoperative pain measure (PPPM) was used to assess the level of pain 4, 6, and 24 h postoperatively in two groups.@* Results@# The FLACC scores of group H 2 h postoperatively were significantly lower than group C (P <0.05). The incidences of significant pain (PPPM scores ≥ 6) 4, 6 and 24 h postoperatively in group H were lower than group C (P <0.05). Altogether, 91.7% of parents in group H and 71.6% in group C assessed the level of pain of children over time. The compliance rate of parents in group H was significantly higher than group C (P <0.05).@*Conclusion @# The holistic approach had a positive effect on reducing postoperative pain for children receiving dental treatment under general anesthesia in the day-surgery operating room.

Fentanyl PCA Monotherapy and Fentanyl TTS Combination Therapy in Post-Operative Pain Management: Analyses of Spontaneous Adverse Drug Reaction Reports

OBJECTIVE: There have been many cases of spontaneous adverse drug reactions to fentanyl at a regional pharmacovigilance center in the hospital. To assess the factors causing the adverse drug reactions reported in patients receiving fentanyl patient-controlled analgesia (PCA) monotherapy or in combination with fentanyl transdermal therapeutic system (TTS) for acute post-operative pain management. METHODS: We conducted a retrospective cohort study with all patients prescribed fentanyl PCA for pain management after orthopedic surgery at a single university hospital from June 2012 to May 2013. We analysed the factors causing adverse drug reactions reported by a spontaneous reporting system in patients receiving fentanyl PCA monotherapy and those receiving fentanyl TTS in combination with fentanyl PCA. RESULTS: Based on the spontaneous adverse drug reaction reporting, the risk ratio for the incidence rate of adverse drug reaction in the fentanyl TTS combination therapy group was 3.04 (95 % CI: 2.4-4.00, P < 0.0001), which was approximately 3-fold higher than that reported for fentanyl PCA monotherapy. Only 60 % of the adverse drug reactions were reported. CONCLUSION: It is inappropriate to add fentanyl TTS to fentanyl PCA to manage post-operative acute pain. There is a need to improve adverse drug reaction reporting. We expect that regular analysis of adverse drug reactions reported at regional pharmacovigilance centre would aid in appropriate drug utilization by patients.

Concurrent Use of Nefopam vs. Ketorolac with Opioid Analgesic for Post-operative Pain Management

OBJECTIVE: To compare the analgesic effects and adverse drug reactions (ADRs) of fentanyl intravenous patient-controlled analgesia (ivPCA) with nefopam, a centrally acting analgesic agent with demonstrated opioid sparing activity, as compared to ketorolac in a tertiary teaching hospital. METHODS: A retrospective evaluation of electronic medical records was conducted on patient records including either nefopam or ketorolac with opioid ivPCA for post-operative pain management in general surgery department from January to December 2014. The status of pain control and ADRs were collected. RESULTS: Out of 6,330 general surgery cases, nefopam was given in 153 prescriptions (6.9%) and ketorolac in 81 prescriptions (3.6%). The level of pain control was not different between two groups (70.9% vs. 75.3%; p = 0.51), but ADRs were more frequently reported in nefopam group (9.8% vs. 2.5%; p < 0.05). New ADRs of hot flushes (n = 1) and paresthesia in hands (n = 1) were reported in nefopam group and they were unlisted in the approved package insert. No serious ADRs were reported in both groups. CONCLUSION: Our findings presented that nefopam showed a similar analgesic effect and higher ADR rates compared to ketorolac as an adjuvant to fentanyl iv PCA for postoperative pain management in general surgery patients in South Korea.

Dolor postoperatorio: factores de riesgo y abordaje / Postoperative pain: risk factors and approach

ResumenEl dolor es una experiencia universal pero única para cada individuo. El proceso patológico que culmina en una intervención quirúrgica es una de las principales fuentes de dolor, muchas veces abordado y manejado de manera subóptima o en entornos que carecen de la organización adecuada. La utilización de la historia clínica y examen físico para la identificación de factores de riesgo conocidos para dolor postoperatorio agudo y crónico son fundamentales al elaborar un plan de manejo del dolor efectivo. Según las recomendaciones, se obtiene una mejor respuesta con el uso de terapia multimodal farmacológica y no farmacológica que involucra celecoxib preoperatorio, anestesia regional periférica o neuraxial, manejo de dolor postoperatorio con antiinflamatorios no esteroideos (AINES), acetaminofén, gabapentina o pregabalina; implementación de terapia cognitiva y de comportamiento. Monitoreo y valoración periódica del paciente para evaluar su respuesta a analgésicos y efectos adversos asociado a coordinación y planeamiento eficaz de protocolos y guías en cada centro de salud, se han visto de utilidad al valorar a un grupo tan heterogéneo e impredecible.

Abstract:Pain is a universal experience but unique for every individual. The pathological processes that end in a surgical intervention are some of the main pain sources, often approached and managed suboptimally or without proper organization. The use of clinical history and physical examination to identify known risk factors to postoperative acute and chronic pain are fundamental to elaborate an effective pain management plan. According to recommendations, the outcome improves with pharmacological and non-pharmacological multimodal analgesia, including celecoxib before surgery, peripheral regional anesthesia or neuraxial techniques, management of postoperative pain with nonsteroidal anti-inflammatory drugs, acetaminophen, gabapentin or pregabalin; implementation of cognitive - behavioral therapy. Monitoring and periodic assessments associated with coordination and planning of protocols and guidelines in every clinical center, have been useful to evaluate a heterogeneous and unpredictable group, in order to establish the patients' response to analgesics and their adverse effects.

Pharmaceutical Interpretation on 2016 Edition of Guidelines for Postoperative Pain Management in the Unit-ed States / 中国药房

OBJECTIVE:To provide reference for postoperative rational selection of analgesia drugs and the optimization of an-algesia plan. METHODS:From the aspect of clinical pharmacists,postoperative pain therapy drugs involved in 6th-22nd chapter of Guidelines for Postoperative Pain Management (called Guideline for short) in the United States. RESULTS:The contents of the Guideline involving postoperative pain therapy drugs included the selection of perioperative therapy drugs and route of administra-tion,multimodal analgesic delivery regimen,individualized drug treatment program,medication monitoring,medication education and postoperative pain management program,etc. The preoperative application of opioids or non-steroidal anti-inflammatory drugs was not recommended in the Guideline due to not benefit from it;for patients who can be given drugs orally,oral administration should be preferred if opioids were administered,and intramuscular injection should be avoided. The multimodal analgesic treat-ment plan combined with non-drug intervention were recommend for postoperative pain. The individualized treatment plan should be chosen according to the patient's specific condition. Clinical pharmacists should pay attention to the degree of sedation respira-tion and the occurrence of ADR in the patients after surgery,and explained the postoperative pain management process,methods of reducing analgesic drugs after discharge to the patiens and their families. CONCLUSIONS:The Guideline about analgesic regimens requirements for perioperative patients provides a reference for clinicians to choose the appropriate individual analgesic regimen.

Iliohypogastric/ilioinguinal nerve block in inguinal hernia repair for postoperative pain management: comparison of the anatomical landmark and ultrasound guided techniques / Bloqueio dos nervos ílio-hipogástrico/ilioinguinal em correção de hérnia inguinal para tratamento da dor no pós-operatório: comparação entre a técnica de marcos anatômicos e a guiada por ultrassom / Bloqueo de los nervios ileohipogástrico/ilioinguinal en corrección de hernia inguinal para el tratamiento del dolor en el postoperatorio: comparación entre la técnica de marcas anatómicas y la guiada por ultrasonido

Objectives: The purpose of this study is to compare the efficacy of iliohypogastric/ilioinguinal nerve blocks performed with the ultrasound guided and the anatomical landmark techniques for postoperative pain management in cases of adult inguinal herniorrhaphy. Methods: 40 patients, ASA I-II status were randomized into two groups equally: in Group AN (anatomical landmark technique) and in Group ultrasound (ultrasound guided technique), iliohypogastric/ilioinguinal nerve block was performed with 20 ml of 0.5% levobupivacaine prior to surgery with the specified techniques. Pain score in postoperative assessment, first mobilization time, duration of hospital stay, score of postoperative analgesia satisfaction, opioid induced side effects and complications related to block were assessed for 24 h postoperatively. Results: VAS scores at rest in the recovery room and all the clinical follow-up points were found significantly less in Group ultrasound (p < 0.01 or p < 0.001). VAS scores at movement in the recovery room and all the clinical follow-up points were found significantly less in Group ultrasound (p < 0.001 in all time points). While duration of hospital stay and the first mobilization time were being found significantly shorter, analgesia satisfaction scores were found significantly higher in ultrasound Group (p < 0.05, p < 0.001, p < 0.001 respectively). Conclusion: According to our study, US guided iliohypogastric/ilioinguinal nerve block in adult inguinal herniorrhaphies provides a more effective analgesia and higher satisfaction of analgesia than iliohypogastric/ilioinguinal nerve block with the anatomical landmark technique. Moreover, it may be suggested that the observation of anatomical structures with the US may increase the success of the block, and minimize the block-related complications. .
