Abstract Purpose: To evaluate the effects of meperidine on fascial healing. Methods: Seventy adult male Sprague-Dawley rats divided into 7 groups with 10 rats in each group. One of these groups was determined as the sham group, 3 of the remaining 6 groups as meperidine groups, and 3 as control groups. These were grouped as 1st, 2nd, and 6th weeks. In the anterior abdominal wall of the rat, the skin was detached and a wound model including the peritoneum was created with a median incision. Mice in the meperidine group were injected with meperidine intraperitoneally (IP) 3 × 20 mg/kg meperidine on postoperative days 0, 1 and 2, and 2 × 20 mg/kg meperidine on postoperative days 3, 4, 5, and 6 after surgical intervention. Similar to the control group, an equal volume of saline was administered, corresponding to the doses. After sacrifice, the midline fascia was used for facial tensile strength measurement, and the other for histopathological analysis. Results: When compared, the meperidine and control groups inflammatory cell density was higher in the 1st week (p < 0.05) in the meperidine group, fibroplasia density was found to be higher at the 2nd week in the meperidine group than the control group (p < 0.05) When the tensile strength in the meperidine and control groups were compared, there was no significant difference (p > 0.05) at each of the three weeks. Conclusion: The application of postoperative systemic meperidine affects positively wound healing in the inflammatory stage and fibroplasia without changing the resistance to traction.

Introducción: La analgesia subaracnoidea es una alternativa para el trabajo de parto por su seguridad y adecuada relación riesgo/beneficio. Objetivo: Evaluar la efectividad de la analgesia durante el trabajo de parto con la comparación de dos métodos analgésicos. Método: Se realizó un estudio cuasiexperimental, longitudinal y prospectivo en 92 gestantes que se atendieron en el Hospital General Docente Abel Santamaría Cuadrado durante el período entre enero de 2014 y enero de 2017. Las pacientes se dividieron en dos grupos de 46 cada uno, al azar, por orden de llegada a la unidad quirúrgica. El grupo A, bupivacaína al 0,5 por ciento, en dosis de 2 mg y fentanilo en dosis de 25 mcg; y grupo B en el que se utilizó petidina en dosis de 25 mg, en todos los casos por vía intratecal. Las variables analizadas fueron: tensión arterial media, frecuencia cardíaca media, saturación parcial de oxígeno, tiempo de inicio de la analgesia, calidad analgésica, efectos adversos y nivel de satisfacción de las pacientes. Se empleó el análisis descriptivo y la diferencia de proporciones. Resultados: El grupo A mantuvo una TAM entre 84 y 88 mmHg, (Z= 6,0 significativa); FC media entre 80 y 88 lat/min, (Z= 1,94 no significativa); SpO2 con una media de 99,2 por ciento. En 46,74 por ciento (43 casos) el tiempo de inicio de la analgesia fue corto (Z= 8,47), siendo Buena en 100 por ciento de los casos (Z= 6,89 significativa), con recién nacido vigoroso en 100 por ciento (Z= 10,25 significativa). La evolución fue satisfactoria en 48,19 por ciento de las pacientes. Presentaron prurito 8,69 por ciento. En el grupo B hubo hipertensión arterial en 2,17 por ciento de los casos, con menos estabilidad de la FC, tiempos mayores de inicio de trabajo de parto en 12,96 por ciento y fue Buena en 40,22 por ciento. Estas pacientes mostraron menos satisfacción (41,30 por ciento). Conclusiones: La administración subaracnoidea de fentanilo/bupivacaína fue más efectiva que la petidina para la analgesia durante el trabajo de parto(AU)
Introduction: Subarachnoid analgesia is an alternative for labor due to its safety and suitable risk-benefit relationship. Objective: To evaluate the effectiveness of analgesia during labor with the comparison of two analgesic methods. Method: A quasiexperimental, longitudinal and prospective study was carried out in 92 pregnant women who attended Abel Santamaría Cuadrado General Teaching Hospital during the period between January 2014 and January 2017. The patients were divided into two groups of 46 each, randomly assigned, in order of arrival to the surgical unit. Group A was treated with intrathecal administration of bupivacaine 0.5 percent, in a dose of 2 mg, and fentanyl in a dose of 25 mcg; and group B was treated with intrathecal administration of pethidine, in a dose of 25 mg. The variables analyzed were mean arterial blood pressure, mean heart rate, partial oxygen saturation, time of onset of analgesia, analgesic quality, adverse effects and level of patient satisfaction. The descriptive analysis and the difference in proportions were used. Results: Group A maintained a mean arterial blood pressure between 84 and 88 mmHg, (Z=6.0 significant); heart rate averages between 80 and 88 beats per minute, (Z=1.94 not significant); partial oxygen saturation with an average of 99.2 percent. In 46.74 percent (43 cases) the time of onset of analgesia was short (Z=8.47), being good in 100 percent of the cases (Z=6.89 significant), with vigorous newborn in 100 percent (Z=10.25 significant). The evolution was satisfactory in 48.19 percent of the patients. They presented pruritus 8.69 percent. In group B, there was arterial hypertension in 2.17 percent of the cases, with less stability of the heart rate, greater times of labor beginning in 12.96 percent and it was good in 40.22 percent. These patients showed less satisfaction (41.30 percent). Conclusions: Subarachnoid administration of fentanyl/bupivacaine was more effective than pethidine for analgesia during labor(AU)

Background: Most parturient women request analgesia, of which, there are two types; opioids and non-opioids. Opioids include morphine and meperidine, while non-opioids, which are milder forms of painkillers, include acetaminophen (paracetamol) and non-steroid anti-inflammatory drugs. The major concerns associated with opioids are the risk of neonatal respiratory depression, the cost and availability.Methods: The aim of this study was to compare the efficacy and safety of paracetamol versus meperidine for intra-partum pain relief. A total of 92 primiparous singleton term pregnant women were randomly allocated to receive intravenous paracetamol (1000 mg), or intramuscular meperidine (50 mg), at the beginning of the active phase of labor. The primary outcome was the labor pain perception, assessed using the visual analogue scale (VAS), at baseline, 15, 30, 60 and 120 minutes after administration of the drug.Results: Women of both groups showed significant reduction of the VAS after administration of the medication. There were no differences between both groups regarding the mode of delivery and the durations of the first or second stages of labor. However, meperidine was associated with higher rates of dizziness and nausea/vomiting. The 1-min Apgar scores were significantly lower in meperidine group. However, there were no differences in the 5-min Apgar score, need for neonatal resuscitation or neonatal respiratory distress.Conclusions: intravenous paracetamol as analgesia during labor is effective with no fetal or maternal adverse effects. Its use should have more chance for intrapartum pain relief. Additionally, it can be used as adjuvant with other types of analgesics.
RESUMO
BACKGROUND: The transrectal ultrasound-guided prostate biopsy (TRUS-PBx) is one of the most common procedures among day care center based urologic procedures. Our aim was to determine if pretreatment with meperidine could improve the quality of anesthesia in patients undergoing deep sedation for TRUS-PBx. METHODS: Sixty male patients (30–80 years; American Society of Anesthesiologists physical status class I or II) scheduled for TRUS-PBx were allocated randomly into two groups. After pretreatment with normal saline (Group C) or intravenous (i.v.) meperidine 0.5 mg/kg (Group M), sedation was induced with i.v. propofol 1.5 mg/kg. Additional doses of i.v. propofol 0.5 mg/kg were administered upon patient movement. During the procedure, hemodynamic variables, patient movement, and the bispectral index were measured. After the procedure, the mean modified observer's assessment of alertness/sedation score (MOASS), postprocedural pain, side effects, and patient satisfaction were evaluated. RESULTS: During the procedure, patient movement was not significantly different between the two groups, but Group M required a significantly lower total propofol dose compared to that of Group C (P = 0.036). After the procedure, the MOASS was comparable between the two groups (P = 0.055), but Group M patients experienced significantly less postprocedural pain (P = 0.012), lower systolic and diastolic blood pressure at 45 (P = 0.044 and P = 0.014) and 60 minutes (P < 0.001 and P = 0.006), and lower incidence of tenesmus than Group C (P = 0.020). CONCLUSIONS: Meperidine can be used as a safe, effective analgesic with deep sedation for patients undergoing TRUS-PBx.

Serotonin syndrome is an unexpected fatal adverse event related to serotonergic medication. This case report is the first report describing the possible treatment effect of famotidine on serotonin syndrome. Furthermore, this is the first case report of serotonin syndrome induced by meperidine alone in a patient with no previous history suggesting a susceptibility to serotonin syndrome. A 70-year-old male with no recent history of serotonergic drug use presented with severe serotonin syndrome following ureteroscopy, possibly due to postoperative meperidine administration. The patient's symptoms included hypertension, tachycardia, tachypnea, hyperthermia, myoclonus, diaphoresis, retching, nausea, agitation, and semicoma mentality with no pupillary light reflex. Symptoms began to subside immediately after the administration of intravenous famotidine for prevention of aspiration pneumonia, with mental and neurological symptoms showing improvement initially, followed by autonomic symptoms. This case report suggests that the histamine type 2 receptor antagonist famotidine may be an effective emergency treatment for serotonin syndrome.

BACKGROUND AND OBJECTIVES: Pain evaluation and the choice of the analgesic best providing its control are extremely important for patients’ quality of life. This study aimed at describing the characteristics which make meperidine unfeasible for pain management, at calling the attention to the incidence of its prescriptions and to the need of a multidisciplinary educative action aiming at decreasing its use, in addition to presenting two opioids as options for analgesia. CONTENTS: National or international scientific and governmental publications between the years 1997 and 2013 used in this study report that meperidine is not indicated for pain management, primarily due to its short action time, presence of neurotoxic metabolite (normeperidine) and possibility of rapidly developing tolerance. CONCLUSION: According to analyzed data, meperidine was the most widely used opioid for analgesic or was among the most prescribed analgesics. This fact shows the real need for an educative multidisciplinary action to promote awareness of meperidine risks and to decrease its prescription. According to searched literature, morphine and methadone have longer action time and higher analgesic potency, with metabolites which are less toxic and noxious for patients as compared to meperidine. .
JUSTIFICATIVA E OBJETIVOS: A avaliação da dor e a escolha do analgésico que mais bem provenha o seu controle são de extrema importância para a qualidade de vida do paciente. O objetivo deste estudo foi elucidar as características que inviabilizam a administração da meperidina para o tratamento da dor, atentar para a incidência de sua prescrição e a necessidade de uma ação educativa multidisciplinar visando à redução do seu uso e apresentar dois opioides como opções de escolha para a analgesia. CONTEÚDO: As publicações científicas e governamentais de âmbito nacional ou internacional entre os anos de 1997 e 2013 utilizadas neste artigo relatam que a meperidina não é indicada para o tratamento da dor devido, principalmente, ao seu curto tempo de ação, presença de metabólito neurotóxico (normeperidina), e a possibilidade de desenvolver tolerância rapidamente. CONCLUSÃO: Segundo os dados das pesquisas analisadas, a meperidina foi o opioide mais utilizado para analgesia ou estava entre os analgésicos mais prescritos. Esse fato relata a real necessidade de uma ação multidisciplinar educativa em prol da conscientização sobre os riscos presentes no tratamento com a meperidina e da diminuição da sua prescrição. De acordo com a literatura consultada, a morfina e a metadona apresentam maior tempo de ação e potência analgésica com metabólitos menos tóxicos e prejudiciais ao paciente que a meperidina. .
RESUMO
Serotonin syndrome is an unexpected adverse reaction of serotonergic medication. Some drugs used by anesthesiologists may cause serotonin syndrome. Serotonin syndrome is known to be related to 5-hydroxytryptamine 1A and 5-hydroxytryptamine 2A agonism. However, recent research has revealed evidence that 5-hydroxytryptamine 3 (5-HT3) antagonism can also play a role in serotonin syndrome. Among the 5-HT3 antagonists, palonosetron is the most highly specific. In this study, we present the first case of fentanyl- and meperidine-induced serotonin syndrome precipitated by palonosetron in general anesthesia.

Although narcotic analgesics are potent releasers of histamine, IgE-mediated allergic reactions to these drugs are rare. Here we report the case of a 56-year-old male who suffered from chronic urticarial and analgesics-induced skin rashes. He visited our allergy clinic to determine alternative analgesics before undergoing surgery. A drug provocation test showed a positive reaction to aspirin, but negative reactions to acetaminophen and celecoxib. Despite careful attention to his drug regimen, during surgery he developed generalized urticaria and flushing. Skin tests of allergy to latex, lidocaine, propofol, rocuronium, flomoxef, meperidine, palonosetron, pyridostigmine, and fentanyl yielded negative results, except for the prick and intradermal tests with meperidine. Thus, this patient had both an aspirin/non-steroidal anti-inflammatory drugs idiosyncrasy and an IgE-mediated hypersensitivity to meperidine.

BACKGROUND: Lack of proper control of acute postoperative pain often leads to lingering or chronic pain. Several studies have emphasized the role of beta-blockers in reducing postoperative pain. Esmolol is a selective short-acting beta-blocker that produces few side effects. The purpose of this study was to examine the effect of intravenous intraoperative esmolol on postoperative pain reduction following orthopedic leg fracture surgery. METHODS: In a clinical trial, 82 patients between 20-65 years of age with tibia fractures and American Society of Anesthesiologists (ASA) physical status I & II who underwent surgery were divided into two groups. Group A received esmolol and group B received normal saline. Postoperative pain was measured at three time points: entering the recovery unit, and at 3 h and 6 h following surgery, using the Visual Analogue Scale (VAS). A P value of < 0.05 was considered significant. RESULTS: Mean VAS scores at all three time points were significantly different between the two test groups (P = 0.02, P = 0.0001, and P = 0.0001, respectively). The consumption of pethidine was lower in group A than in group B (P = 0.004) and the duration of its effect was significantly longer in time (P = 0.026). CONCLUSIONS: Intravenous intraoperative esmolol is effective in the reduction of postoperative pain following leg fracture surgery. It reduced opioid consumption following surgery and delayed patient requests for analgesics.

RESUMO
BACKGROUND: Shivering related to spinal anesthesia may interfere with monitoring and is uncomfortable. The aim of the present study was to investigate low-dose intrathecal meperidine for the prevention of shivering after induction of spinal anesthesia in parturients with cesarean section. METHODS: This was a prospective randomized, double-blind, placebo-controlled trial including 100 parturients, of American Society of Anesthesiologists (ASA) physical status I or II, scheduled for elective cesarean section under spinal anesthesia who were randomly assigned to a meperidine (0.2 mg/kg) plus hyperbaric lidocaine (5%, 75 mg, n = 50; group M) group or a placebo plus hyperbaric lidocaine (5%, 75 mg, n = 50; group L) group. Demographic and surgical data, adverse events, and the mean intensity for each parturient were assessed during the entire study period by a blinded observer. RESULTS: There were no significant differences between the two study groups regarding the demographic and surgical data (P > 0.05). The incidence of shivering during the entire study period significantly decreased in the group of parturients who received intrathecal meperidine (P = 0.04). There were no significant differences in nausea and vomiting between the two groups. CONCLUSIONS: Low-dose intrathecal meperidine (10 mg) is safe and effective in reducing the incidence and severity of shivering associated with spinal anesthesia in parturients with cesarean section.

RESUMO
Objective To investigate the effect of different intrathecal doses of meperidine on shivering during cesarean delivery under spinal-epidural anesthesia.Methods Sixty parturient women,ASA grade Ⅰ-Ⅱ grade,scheduled for cesarean delivery were enrolled in four groups by random digits table with 15 cases each group.All patients underwent combined spinal-epidural anesthesia.Spinal anesthesia consisted of isobaric bupivacaine 0.5% (10 mg) in the standard group (group A),isobaric bupivacaine 0.5% (10 mg) plus 5 mg meperidine in group B,isobaric bupivacaine 0.5% (10 mg) plus 10 mg meperidine in group C,isobaric bupivacaine 0.5%(10 mg) plus 15 mg meperidine in group D.The signs and symptoms were recorded 10,20,30,60 min after anesthesia respectively.Results All patients were successfully operated,not unexpected.Four groups at each time point of vital signs,nausea and vomiting,and the number of cases of neonatal 1,5 min Apgar scores was no significant difference (P > 0.05).Group A of shivering and the third grade shivering were significantly more than the number of group B,C,D(11 cases vs.2,1,1 cases;4 cases vs.0,0,0 cases,P< 0.01).Conclusion Epidural anesthesia,intrathecal meperidine 5-15 mg can effectively prevent shivering in cesarean section.
RESUMO
BACKGROUND: Shivering is a frequent event during spinal anesthesia and meperidine is a well-known effective drug for prevention and treatment of shivering. Nefopam is a non-opiate analgesic and also known to have an anti-shivering effect. We compared nefopam with meperidine for efficacy of prevention of shivering during spinal anesthesia. METHODS: Sixty five patients, American Society of Anesthesiologists physical status I or II, aged 20-65 years, scheduled for elective orthopedic surgery under spinal anesthesia were investigated. Patients were randomly divided into two groups, meperidine (Group M, n = 33) and nefopam (Group N, n = 32) groups. Group M and N received meperidine 0.4 mg/kg or nefopam 0.15 mg/kg, respectively, in 100 ml of isotonic saline intravenously. All drugs were infused for 15 minutes by a blinded investigator before spinal anesthesia. Blood pressures, heart rates, body temperatures and side effects were checked before and at 15, 30, and 60 minutes after spinal anesthesia. RESULTS: The incidences and scores of shivering were similar between the two groups. The mean arterial pressures in Group N were maintained higher than in Group M at 15, 30, and 60 minutes after spinal anesthesia. The injection pain was checked in Group N only and its incidence was 15.6%. CONCLUSIONS: We conclude that nefopam can be a good substitute for meperidine for prevention of shivering during spinal anesthesia with more stable hemodynamics, if injection pain is effectively controlled.

Objective To compare the efficacy of dexmedetomidine and pethidine for prevention of postoperative shivering in patients requiring general anesthesia.Methods Sixty ASA Ⅰ-Ⅲ patients of both sexes,aged 18-75 yr,weighing 40-85 kg,were randomly divided into 2 groups (n =30 each) ∶ pethidine group (group P) and dexmedetomidine group (group D).At the end of pneumoperitoneum,pethidine 0.5 mg/kg and dexmedetomidine 1 μg/kg were infused intravenously over 10 min in groups P and D,respectively.The shivering,respiratory depression,somnolence,nausea and vomiting,bradycardia and hypotension were recorded within 1 h after operation.Results There were no significant differences in the incidence and degree of shivering between group D and group P (P > 0.05).The incidences of respiratory depression and nausea and vomiting were significantly lower,and the incidence of bradycardia was significantly higher in group D than in group P(P < 0.05).Conclusion The efficacy of dexmedetomidine for prevention of postoperative shivering is better than pethidine in patients requiring general anesthesia.
RESUMO
QT prolongation is a serious adverse drug effect, which is associated with an increased risk of Torsade de pointes and sudden death. Many drugs, including both cardiac and non-cardiac drugs, have been reported to cause prolongation of QT interval. Although meperidine has not been considered proarrhythmic, we present a unique case of a 16-year-old boy without an underlying cardiac disease, who developed polymorphic ventricular tachycardia, ventricular fibrillation and QT prolongation after an intravenous meperidine injection. He had no mutation in long QT syndrome genes (KCNQ1, KCNH2, and SCN5A), but single nucleotide polymorphisms were reported, including H558R in SCNA5A and K897T in KCNH2.
