Effect of magnesium sulfate with ketamine infusions on intraoperative and postoperative analgesia in cancer breast surgeries: a randomized double-blind trial

Abstract Background Opioids are the cornerstone in managing postoperative pain; however, they have many side effects. Ketamine and Magnesium (Mg) are NMDA receptor antagonists used as adjuvant analgesics to decrease postoperative opioid consumption. Objective We assumed that adding Mg to ketamine infusion can improve the intraoperative and postoperative analgesic efficacy of ketamine infusion alone in cancer breast surgeries. Methods Ninety patients aged between 18 and 65 years and undergoing elective cancer breast surgery were included in this prospective randomized, double-blind study. Group K received ketamine 0.5 mg.kg-1 bolus then 0.12 mg.kg-1.h-1 infusion for the first 24 hours postoperatively. Group KM: received ketamine 0.5 mg.kg-1 and Mg sulfate 50 mg.kg-1, then ketamine 0.12 mg.kg-1.h-1 and Mg sulfate 8 mg.kg-1.h-1 infusions for the first 24 hours postoperative. The primary outcome was the morphine consumption in the first 24 hours postoperative, while the secondary outcomes were: intraoperative fentanyl consumption, NRS, side effects, and chronic postoperative pain. Results Group KM had less postoperative opioid consumption (14.12 ± 5.11 mg) than Group K (19.43 ± 6.8 mg). Also, Group KM had less intraoperative fentanyl consumption. Both groups were similar in postoperative NRS scores, the incidence of side effects related to opioids, and chronic neuropathic pain. Conclusion Adding Mg to ketamine infusion can safely improve intraoperative and postoperative analgesia with opioid-sparing effect in cancer breast surgery.

Effect of preoperative anxiety level on postoperative pain, analgesic consumption in patients undergoing laparoscopic sleeve gastrectomy: an observational cohort study

Abstract Backgraund: This prospective observational cohort study aimed to investigate the relationship between preoperative anxiety levels and postoperative pain and analgesic requirement in patients undergoing laparoscopic sleeve gastrectomy. Methods: Forty two female patients with body mass index ≥ 35, who underwent laparoscopic sleeve gastrectomy for treatment of obesity were included in the study. Spielberger's state and trait anxiety scales were used in this study. Demographic data of the patients, anesthetic and analgesic drugs during the surgery, pain levels measured with verbal analog scale at the postoperative 1st, 4th, 12th, and 24th hour, sedation levels measured with the Ramsay sedation scale, and the amount of analgesic consumed were recorded. Anesthesiologist, surgeon, and patient were not informed of the anxiety level results. The relationship between preoperative anxiety and postoperative pain and analgesic consumption was evaluated by Spearman's correlation analysis. Stepwise multiple linear regression analysis was applied. Normal Distribution control was performed by applying the Shapiro-Wilk test to residual values obtained from the final model. Results: There was no relationship between trait anxiety level and postoperative pain and analgesic consumption. A correlation was found between state anxiety level and pain level up to 24 hours and analgesic consumption (p < 0.05). According to the obtained model it had been observed that the university graduates consumed more analgesic compared to other education level groups. Conclusion: In this study, a relationship was found between preoperative state anxiety level and 24-hour pain scores and analgesic consumption in patients who underwent laparoscopic sleeve gastrectomy under general anesthesia.

Introducción: El cuidado postoperatorio de la rinoplastia ha evolucionado, paralelamente, al desarrollo de la técnica quirúrgica. Existen varias recomendaciones, sin embargo, hay una gran variabilidad interprofesional de las indicaciones post quirúrgicas. Objetivo: Realizar una revisión sistemática de la literatura científica sobre los cuidados post operatorios de la rinoplastia. Material y Método: Para la realización de este estudio se llevaron a cabo búsquedas en PubMed y en Cochrane Database of Systematic Reviews con los perfiles: ([rhinoplasty] AND [post operative care]) y ([rhinoplasty] AND [post surgical care]). Se seleccionaron los artículos publicados en los últimos 10 años, desde 2013 hasta 2023, ambos inclusive. Resultados: Los documentos analizados recogen la evidencia de los diferentes métodos de cuidados post quirúrgicos en rinoplastia. Estos confirman la utilización de corticoides en el período postoperatorio, así como el reposo en 90° y exponen la variabilidad interprofesional que existe en el protocolo postquirúrgico de esta cirugía. Conclusión: El uso de corticoides y el reposo en 90° disminuyen las complicaciones postquirúrgicas de la rinoplastia. Debe existir una clara información sobre lo que el paciente debe esperar post cirugía. El uso de opioides debe ser restringido y la analgesia debe ser multimodal. Es preciso realizar estudios futuros con mayor nivel de evidencia y tener protocolos uniformes para la práctica clínica.

Introduction: The postoperative care of rhinoplasty has evolved along with the development of the surgical technique. There are several recommendations, however there is enormous interprofessional variability of post-surgical indications. Aim: To carry out a systematic review of the scientific literature on rhinoplasty postoperative care. Material and Method: To carry out this study, searches were carried out in PubMed and in the Cochrane Database of Systematic Reviews with the profiles: ([rhinoplasty] AND [post operative care]) and ([rhinoplasty] AND [post surgical care]). Articles published in the last 10 years were selected, from 2013 to 2023, both inclusive. Results: The documents analyzed collect the evidence of the different methods of post-surgical care in rhinoplasty, they confirm the use of corticosteroids in the postoperative period as well as rest at 90° and expose the interprofessional variability that exists in the post-surgical protocol of this surgery. Conclusion: The use of corticosteroids and rest at 90° reduce the post-surgical complications of rhinoplasty. There must be clear information about what the patient should expect post surgery. The use of opioids must be restricted and analgesia must be multimodal. It is necessary to carry out future studies with a higher level of evidence and have uniform protocols for clinical practice.

Treatment duration of wrist-ankle acupuncture for relieving post-thyroidectomy pain: A randomized controlled trial / 中西医结合学报

BACKGROUND@#Treatment duration of wrist-ankle acupuncture (WAA) is uncertain for post-thyroidectomy pain relief.@*OBJECTIVE@#This study evaluated the effect of different WAA treatment duration on post-operative pain relief and other discomforts associated with thyroidectomy.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#This randomized controlled trial was conducted at a single research site in Guangzhou, China. A total of 132 patients receiving thyroidectomy were randomly divided into the control group (sham WAA, 30 min) and three intervention groups (group 1: WAA, 30 min; group 2: WAA, 45 min; group 3: WAA, 60 min), with group allocation ratio of 1:1:1:1. Acupuncture was administered within 1 hour of leaving the operating room.@*OUTCOMES AND MEASURES@#Primary outcome was patients' pain at the surgical site assessed by visual analogue scale (VAS) at the moment after acupuncture treatment (post-intervention). Secondary outcomes included the patients' pain VAS scores at 6, 12, 24, 48 and 72 h after the thyroidectomy, the 40-item Quality of Recovery (QoR-40) score, the grade of post-operative nausea and vomiting (PONV), and the use of additional analgesic therapy.@*RESULTS@#The adjusted mean difference (AMD) in VAS scores from baseline to post-intervention in group 1 was -0.89 (95% confidence interval [CI], -1.02 to -0.76). The decrease in VAS score at post-intervention was statistically significant in group 1 compared to the control group (AMD, -0.43; 95% CI, -0.58 to -0.28; P < 0.001), and in groups 2 and 3 compared to group 1 (group 2 vs group 1: AMD, -0.65; 95% CI, -0.81 to -0.48; P < 0.001; group 3 vs group 1: AMD, -0.66; 95% CI, -0.86 to -0.47; P < 0.001). The VAS scores in the four groups converged beyond 24 h after the operation. Fewer patients in group 2 and group 3 experienced PONV in the first 24 h after operation. No statistical differences were measured in QoR-40 score and the number of patients with additional analgesic therapy.@*CONCLUSION@#Compared with the 30 min intervention, WAA treatment with longer needle retention time (45 or 60 min) had an advantage in pain relief within 6 h after surgery. WAA's analgesic effect lasted for 6-12 h post-operatively. Please cite this article as: Han XR, Yue W, Chen HC, He W, Luo JH, Chen SX, Liu N, Yang M.

Expert consensus on late stage of critical care management / 中华内科杂志

We wished to establish an expert consensus on late stage of critical care (CC) management. The panel comprised 13 experts in CC medicine. Each statement was assessed based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) principle. Then, the Delphi method was adopted by 17 experts to reassess the following 28 statements. (1) ESCAPE has evolved from a strategy of delirium management to a strategy of late stage of CC management. (2) The new version of ESCAPE is a strategy for optimizing treatment and comprehensive care of critically ill patients (CIPs) after the rescue period, including early mobilization, early rehabilitation, nutritional support, sleep management, mental assessment, cognitive-function training, emotional support, and optimizing sedation and analgesia. (3) Disease assessment to determine the starting point of early mobilization, early rehabilitation, and early enteral nutrition. (4) Early mobilization has synergistic effects upon the recovery of organ function. (5) Early functional exercise and rehabilitation are important means to promote CIP recovery, and gives them a sense of future prospects. (6) Timely start of enteral nutrition is conducive to early mobilization and early rehabilitation. (7) The spontaneous breathing test should be started as soon as possible, and a weaning plan should be selected step-by-step. (8) The waking process of CIPs should be realized in a planned and purposeful way. (9) Establishment of a sleep-wake rhythm is the key to sleep management in post-CC management. (10) The spontaneous awakening trial, spontaneous breathing trial, and sleep management should be carried out together. (11) The depth of sedation should be adjusted dynamically in the late stage of CC period. (12) Standardized sedation assessment is the premise of rational sedation. (13) Appropriate sedative drugs should be selected according to the objectives of sedation and drug characteristics. (14) A goal-directed minimization strategy for sedation should be implemented. (15) The principle of analgesia must be mastered first. (16) Subjective assessment is preferred for analgesia assessment. (17) Opioid-based analgesic strategies should be selected step-by-step according to the characteristics of different drugs. (18) There must be rational use of non-opioid analgesics and non-drug-based analgesic measures. (19) Pay attention to evaluation of the psychological status of CIPs. (20) Cognitive function in CIPs cannot be ignored. (21) Delirium management should be based on non-drug-based measures and rational use of drugs. (22) Reset treatment can be considered for severe delirium. (23) Psychological assessment should be conducted as early as possible to screen-out high-risk groups with post-traumatic stress disorder. (24) Emotional support, flexible visiting, and environment management are important components of humanistic management in the intensive care unit (ICU). (25) Emotional support from medical teams and families should be promoted through"ICU diaries"and other forms. (26) Environmental management should be carried out by enriching environmental content, limiting environmental interference, and optimizing the environmental atmosphere. (27) Reasonable promotion of flexible visitation should be done on the basis of prevention of nosocomial infection. (28) ESCAPE is an excellent project for late stage of CC management.

Determination of prevalence, characteristics, management and related factors for pain in the older adults: pain among nursing home residents

This study aimed to determine pain assessment approaches and pain management strategies in elderly people in a nursing home.The cross-sectional-descriptive study sample consisted of 147 older adults living in a nursing home in Turkey in 2019. They all agreed to participate in the study (n = 147); however, as our research was about older adultswith pain problems, the study was completed with a total of 108 older adultsexperiencing pain problems. The participants' average age was 73.60 ± 6.97 years. Geriatric pain scale scores were higher for women aged 75 years and over, those who had a chronic disease and those who received analgesics, and there was a statistically significant difference between the mean scores (p < 0.05). Nurses must pay attention to pain assessment and management in nursing homes because of the adverse effects of pain on older adults' health status, vital functions, and well-being.

Clinical research and application of preemptive analgesia in dental treatment / 中华口腔医学杂志

Preemptive analgesia refers to the use of analgesics or regional nerve block in advance of nerve conduction changing or nerve remodeling caused by traumatic stimulation, so as to achieve better postoperative pain relief and to prevent postoperative pain hypersensitivity. Preemptive analgesia minimizes or prevents postoperative pain by reducing peripheral and central sensitization, which thereby limit the pain cascade. This paper briefly introduces the mechanism and methods of preemptive analgesia, as well as its application and research progress in the field of oral treatment. With the increased requirements for comfortable medical treatments and popularization of multimodal analgesia in pain management of oral surgery, preemptive analgesia will be more widely studied and applied in oral diagnosis and treatment.

A novel cell tool for α2δ-1-NMDAR target-based analgesic drug discovery / 生物工程学报

The α2δ-1 protein coded by Cacna2d1 is dramatically up-regulated in dorsal root ganglion (DRG) neurons and spinal dorsal horn following sensory nerve injury in various animal models of neuropathic pain. Cacna2d1 overexpression potentiates presynaptic and postsynaptic NMDAR activity of spinal dorsal horn neurons to cause pain hypersensitivity. The α2δ-1-NMDAR interaction promotes surface trafficking and synaptic targeting of NMDARs in neuropathic pain caused by chemotherapeutic agents and peripheral nerve injury, as well as in other pathological conditions such as in the paraventricular nucleus (PVN) with neurogenic hypertension and in the brain with ischemic stroke. The lentiviral transfection method was used to construct a human embryonic kidney HEK293T cell line that could stably express α2δ-1-NMDAR complex. A stably transfected cell line was observed by florescence microscope, and identified by RT-qPCR and Western blotting. The results showed that the HEK293T cell line was successfully transfected and the genes could be stably expressed. Subsequently, the transfected cell line was successfully developed into a target drug screening system using patch clamp techniques. It provides a promising cell model for further research on the interaction mechanism of α2δ-1-NMDAR complex and drug screening for chronic pain and related diseases with low side effects.

Using a consensus acupoints regimen to explore the relationship between acupuncture sensation and lumbar spinal postoperative analgesia: A retrospective analysis of prospective clinical cooperation / 中西医结合学报

OBJECTIVE@#This study evaluated the effectiveness of acupuncture treatment on postoperative pain in patients with degenerative lumbar spine disease, and explored the relationship between the postoperative analgesic effect of acupuncture and the sensation of acupuncture experienced by the patients.@*METHODS@#This retrospective study analyzed the medical records of 97 patients who had undergone an operation by the same surgeon due to degenerative lumbar disease. These patients were divided into acupuncture group (n = 32), patient-controlled analgesia (PCA) group (n = 27), and oral analgesia group (n = 38) according to the different postoperative analgesic methods. During their hospitalization, patients completed daily evaluations of their pain using a visual analogue scale (VAS), and injection times of supplemental meperidine were recorded. Also, the Chinese version of the Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS) was used in the acupuncture group.@*RESULTS@#Each of the three treatment groups showed significant reductions in postoperative pain, as shown by reduced VAS scores. The acupuncture group, however, had less rebound pain (P < 0.05) than the other two groups. Both the acupuncture and PCA groups experienced acute analgesic effects that were superior to those in the oral analgesia group. In addition, the higher the C-MASS index on the second day after surgery, the lower the VAS score on the fourth day after surgery. There was also a significant difference in the "dull pain" in the acupuncture sensation.@*CONCLUSION@#The results demonstrated that acupuncture was beneficial for postoperative pain and discomfort after simple surgery for degenerative spinal disease. It is worth noting that there was a disproportionate relevance between the patient's acupuncture sensation and the improvement of pain VAS score.

OBJECTIVES@#To investigate the effect of sequential sedative and analgesic drugs in preventing delirium and withdrawal symptoms in children after ventilator weaning.@*METHODS@#A retrospective analysis was performed on 61 children who were admitted and received mechanical ventilation support for ≥5 days in the Pediatric Intensive Care Unit of Dongguan Children's Hospital Affiliated to Guangdong Medical University from December 2019 to September 2021. The children were divided into a control group (30 children with no maintenance of analgesic and sedative drugs after ventilator weaning) and an observation group (31 children with sequential sedative and analgesic drugs maintained for 48 hours after ventilator weaning). The two groups were compared in terms of the Sophia Observation Withdrawal Symptoms Scale (SOS) score, the Pediatric Delirium Scale (PD) score, the Richmond Agitation-Sedation Scale (RASS) score, and the incidence rates of delirium or withdrawal symptoms at 24 and 72 hours after ventilator weaning.@*RESULTS@#There was no significant difference in the incidence rate of delirium at 24 hours and 72 hours after ventilator weaning between the two groups (P>0.05). Compared with the control group, the observation group had significantly lower incidence rate of withdrawal symptoms and scores of SOS, PD, and RASS scales at 24 hours and 72 hours after ventilator weaning (P<0.01).@*CONCLUSIONS@#Sequential sedation and analgesia after ventilator weaning can reduce the incidence of withdrawal symptoms within 72 hours after ventilator weaning, but it cannot reduce the incidence rate of delirium.

Effect of closure of anterior abdominal wall layers on early postoperative findings at cesarean section: A prospective cross-sectional study

Abstract Objective To investigate the effect of closure types of the anterior abdominal wall layers in cesarean section (CS) surgery on early postoperative findings. Methods The present study was designed as a prospective cross-sectional study and was conducted at a university hospital between October 2018 and February 2019. A total of 180 patients who underwent CS for various reasons were enrolled in the study. Each patient was randomly assigned to one of three groups: Both parietal peritoneum and rectus abdominis muscle left open (group 1), parietal peritoneum closure only (group 2), and closure of the parietal peritoneum and reapproximation of rectus muscle (group 3). All patients were compared in terms of postoperative pain scores (while lying down and duringmobilization), analgesia requirement, and return of bowel motility. Results The postoperative pain scores were similar at the 2nd, 6th, 12th, and 18th hours while lying down. During mobilization, the postoperative pain scores at 6 and 12 hours were significantly higher in group 2 than in group 3. Diclofenac use was significantly higher in patients in group 1 than in those in group 2. Meperidine requirements were similar among the groups. There was no difference between the groups' first flatus and stool passage times. Conclusion In the group with only parietal peritoneum closure, the pain scores at the 6th and 12th hours were higher. Rectus abdominismuscle reapproximations were found not to increase the pain score. The closure of the anterior abdominal wall had no effect on the return of bowel motility.

Use of gabapentin in management of postoperative pain after crosslinking / Uso da gabapentina no manejo da dor pós-operatória do crosslinking

ABSTRACT Objective: The objective was to evaluate the efficacy of gabapentin in the management of neuropathic pain in patients with keratoconus, who were treated with fast (10 minutes) epi-off corneal crosslinking (CXL). Methods: This was a prospective, double-blind, randomized study. The sample comprised patients with bilateral progressive keratoconus, aged 12 years or older, who underwent a bilateral epi-off corneal CXL (fast - 10 minutes) procedure. One group was given placebo orally, and the other group received gabapentin 600 mg orally, both preoperatively. The visual analogue scale (VAS) was applied to record postoperative pain up to 48 hours after procedure. The study was conducted at the Belotto Stock Centro Oftalmológico, in the city of Joaçaba, Santa Catarina, Brazil, from June 2018 to September 2019. Results: At no point in the study significant differences were observed between groups, in terms of pain intensity measured by means of the VAS questionnaire, or of opioid use (Paco®), though opioid consumption was 21% lower in the group receiving gabapentin. Conclusion: We concluded gabapentin has no efficacy in postoperative pain control after epi-off corneal CXL (fast - 10 minutes). Although there was no statistically significant difference, the group that received gabapentin suffered less pain, resulting in lower opioid consumption. UTN number: U1111-1256-0330.

RESUMO Objetivo: Avaliar a eficácia do uso da gabapentina no manejo da dor neuropática em pacientes portadores de ceratocone submetidos ao tratamento de crosslinking corneano epi-off fast de 10 minutos. Métodos: Tratou-se de pesquisa prospectiva, duplo-cega, randomizada. A amostra foi composta de pacientes com ceratocone progressivo bilateral, a partir dos 12 anos de idade, submetidos ao procedimento de crosslinking corneano acelerado epi-off fast de 10 minutos bilateral. Um grupo recebeu placebo via oral e o outro, gabapentina 600mg, via oral, ambos no pré-operatório. A Escala Visual Analógica foi aplicada para registrar a dor pós-operatória até 48 horas após o procedimento. A pesquisa foi realizada no período de junho de 2018 a setembro de 2019 em um centro oftalmológico. Resultados: Não foram observadas diferenças estatísticas significativas para ambos os grupos, tanto na intensidade da dor medida pela Escala Visual Analógica, como na redução do uso do opioide (Paco®), em qualquer horário analisado durante um período de 48 horas. No entanto, houve redução de 21% no consumo de opioides pelo grupo que fez uso da gabapentina. Conclusão: A gabapentina não demonstrou eficácia no controle da dor no pós-operatório do crosslinking corneano epi-off fast de 10 minutos. No entanto, observou-se que, mesmo não havendo diferença estatisticamente significativa, houve diminuição da dor no grupo em que foi usada a gabapentina, resultando na redução do consumo de opioides. Número UTN: U1111-1256-0330.

Prescriptions of analgesics and anti-inflammatory drugs in municipalities from a Brazilian Southeast state

Abstract The objective of this study was to describe dental prescriptions of non-steroidal anti-inflammatory drugs (NSAID), opioids, and analgesics dispensed by the Brazilian National Health System (BNHS, SUS in Portuguese) of a Southeastern state from January to December 2017, and to analyze their association with socioeconomic and oral health care services' characteristics at municipal level. Data were collected from the Brazilian Integrated Pharmaceutical Care Management System. Medicines were grouped according to the Anatomical Therapeutic Chemical Classification System. The total number of Defined Daily Doses (DDD) and DDD per 1,000 inhabitants (inhab.) per year were presented and compared between groups of municipalities. Data analysis used the Classification and Regression Tree model performed with IBM SPSS 25.0. The total number of NSAID, opioids, and analgesics prescriptions was 70,747 and accounted for 354,221.13 DDD. The most frequently prescribed medicine was ibuprofen (n = 24,676; 34.88%). The number of dental practitioners in the BNHS per 1,000 inhab. (p < 0.001), first dental appointment coverage (p = 0.010), oral health teams per 1,000 inhab. (p=0.022), and the proportion of rural population (p = 0.014) were variables positively associated with the number of DDD of NSAID per 1,000 inhab. per year. Bolsa Família program coverage per 1,000 inhab. (p = 0.022) was negatively associated with NSAID prescription. Regarding analgesics, first dental appointment coverage (p=0.002) and Bolsa Família program coverage per 1,000 inhab. (p = 0.012) were positively associated with DDD per 1,000 inhab. per year. In conclusion, dental prescriptions of analgesics and NSAID in the BNHS were associated with socioeconomic and oral health care services' characteristics.
