RESUMO
Introducción: La meperidina (o petidina) es un opioide sintético que tiene propiedades anestésicas locales bien conocidas, y ha sido utilizada por vía intratecal en cirugía general, urológica y obstétrica de forma segura. Este puede ser usado en anestesia espinal en paciente con hipersensibilidad a los anestésicos locales. Objetivo: Describir el manejo anestésico en una paciente con hipersensibilidad a los anestésicos locales con uso de meperidina intratecal. Presentación del caso: Se presenta una paciente femenina de 54 años de edad con historia previa de hipersensibilidad a los anestésicos locales, programada para colporrafia anterior, a la cual se le realiza una técnica regional, administrando meperidina intratecal. Para la analgesia posoperatoria se suministró diclofenaco de sodio en dosis única de 75 mg, por vía IV previo a la incisión. Conclusiones: Con la técnica descrita se logra un bloqueo sensitivo y motor adecuado, estabilidad de los signos vitales intraoperatoria y recuperación óptima en el posoperatorio inmediato. Es una alternativa más en el manejo de los pacientes con hipersensibilidad a los anestésicos locales(AU)
Introduction: Meperidine (or pethidine) is a synthetic opioid with well-known local anesthetic properties. It has been safely used intrathecally in general, urological and obstetric surgery. This can be used in spinal anesthesia in patients with hypersensitivity to local anesthetics. Objective: To describe anesthetic management of a patient with hypersensitivity to local anesthetics with the use of intrathecal meperidine. Case presentation: The case is presented of a 54-year-old female patient with a previous history of hypersensitivity to local anesthetics, scheduled for anterior colporrhaphy, who is performed regional technique, administering intrathecal meperidine. For post-operative analgesia, diclofenac sodium was administered intravenously in a single dose of 75 mg before the incision. Conclusions: The described technique allowed to achieve adequate sensory and motor block, stability of intraoperative vital signs, and optimal recovery in the immediate postoperative period. It is another alternative in the management of patients with hypersensitivity to local anesthetics(AU)

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)

Abstract Objective To compare low doses of pethidine with dipyrone in labor analgesia. Methods In a randomized prospective study conducted by Universidade de Fortaleza, in the state of Ceará, Brazil, between May and December 2016, 200 full-term parturients, with very painful uterine contractions and exhibiting uterine cervix dilatation ≥ 5 cm, were selected to receive a single intravenous dose of either 0.25 mg/kg of pethidine (n = 100) or of 25 mg/kg of dipyrone (n = 100). Pain was assessed using the visual analogue scale. The data were analyzed using the Student t-test, the chi-square test and the likelihood ratio. Results There was a significant improvement in pain in 35% of the parturients. Both drugs presented a similar analgesic effect 1 hour after the intervention (p = 0.692). There was no analgesic effect during the evaluation of the second hour after the intervention with pethidine or dipyrone. There were no adverse effects, such as maternal drowsiness, nausea or vomiting, related to the drugs used. Conclusion Pethidine in low doses and dipyrone presented equivalent analgesia during labor.

BACKGROUND/AIMS: Cooperation of patients plays an essential role during gastric endoscopic submucosal dissection (ESD) for successful outcomes. We aimed to assess the efficacy and safety of a patient-positioning device (EZ-FIX®) during ESD for gastric epithelial neoplasm.MATERIALS AND METHODS: In this prospective study, 86 consecutive patients with gastric epithelial neoplasm scheduled for ESD at the Pusan National University Hospital were included and randomly assigned to the EZ-FIX® (n=44) or non-EZ-FIX® (n=42) groups. The primary outcomes measured were endoscopist satisfaction profiles and contribution level of EZ-FIX® to the procedure.RESULTS: No significant differences were observed between the two groups regarding patients' clinicopathologic characteristics, though the mean procedure time was longer in the EZ-FIX® group (P=0.044). In the EZ-FIX® group, 16 patients (36.4%) were categorized as a contribution group. Subgroup analysis between the contribution and non-contribution groups revealed that the contribution group had a larger lesion size (P=0.043) and a longer procedure time (P=0.037) and showed a higher patient's movement score (P < 0.001) with a higher dosage of propofol (P=0.004) and pethidine (P=0.001) required. Endoscopist satisfaction scores on sedation (P < 0.001) and overall procedure (P=0.010) were lower in the contribution group.CONCLUSIONS: Thus, EZ-FIX® might be helpful especially for patients who are expected to exhibit uncooperative sedation or those with a large lesion size, which would necessitate a longer procedure time.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a common complication following laparascopic surgery. This study compared the effect of intraperitoneal versus intravenous dexamethasone for reducing PONV after gynecological laparoscopic surgeries. METHODS: Eighty adult female patients, American Society of Anesthesiologists physical status I–II, scheduled for gynecological laparoscopic surgery were randomized to receive 8 mg dexamethasone intravenously (IV) (n = 40) or intraperitoneally (IP) (n = 40). The primary outcome was the PONV incidence during the first 24 h after laparoscopy. Secondary outcomes included visual analogue scale (VAS) pain scores, total rescue analgesic consumption during the first 24 h postoperatively, the need for rescue antiemetic drugs, and the incidence of complications that may accompany these medications. RESULTS: Eleven women (27.5%) in the IV group, versus only 3 (7.5%) women in the IP group, experienced nausea during the first 24 h postlaparoscopy (P = 0.037). However, 5 patients (12.5%) in the IV group, versus only 2 patients (5.0%) in the IP group, experienced vomiting (P = 0.424). No statistically significant differences were seen in the severity of nausea or the need for rescue antiemetics. The IV group had a higher rate of side-effects than the IP group (27.5% vs. 7.5%, P = 0.037). Headache and dizziness were common side effects in the IV dexamethasone group. The groups did not differ significantly in terms of mean VAS score for pain and total meperidine consumption during the first 24 h postoperatively. CONCLUSIONS: Intraperitoneal dexamethasone at a dose of 8 mg at the end of gynecological laparoscopy reduces the incidence of postoperative nausea.

ABSTRACT The treatment of hemorrhoidal disease has never been as innovated as in recent decades. The transanal hemorrhoidal dearterialization with Doppler (THD) was described under general anesthesia or spinal blockage and there is no use of local anesthesia reports. This study aims to evaluate the safety of the use of local anesthesia with sedation in THD. For this purpose, two cases are reported describing the technical and safety analysis and results. Both patients were women with grade II and III hemorrhoidal disease. These patients underwent pre-anesthetic sedation with intravenous diazepam, then were positioned in lithotomy and sedated with midazolam and pethidine. The intersphincteric blockage was followed by THD with mucopexy. One patient made a small submucosal hematoma without expansion. The patients were stable and comfortable throughout the procedure. Both were discharged the next day, with regular analgesia. In the seventh postoperative day, both had mild annoyance at constant tenesmus, which was reduced gradually. The cases illustrate that THD is feasible when performed with local anesthesia and sedation, as it is safe and effective. This new technology can be incorporated into services that have a local anesthesia protocol as their standard.
RESUMO O tratamento da doença hemorroidária nunca foi tão inovado como nas últimas décadas. A desarterialização hemorroidária transanal é uma dessas inovações. Foi originalmente descrita sob anestesia geral ou bloqueio espinal e não há relatos de utilização de anestesia local. Assim, este estudo visa avaliar a segurança do uso da anestesia local com sedação na desarterialização hemorroidária transanal. Para tal, dois casos são relatados com descrição da técnica e análise da segurança e resultados. Ambas pacientes eram mulheres com doença hemorroidária grau II e III. Foram submetidas à indução anestésica, posicionadas em litotomia e sedadas com midazolan e petidina. Realizou-se bloqueio interesfincteriano seguido de desarterialização hemorroidária transanal com doppler associado a mucopexia. Uma das pacientes fez um hematoma submucoso pequeno, sem expansão. As pacientes ficaram estáveis e confortáveis durante todo o procedimento. Ambas receberam alta no dia seguinte, com analgesia habitual. No sétimo dia do pós-operatório, ambas apresentavam incômodo leve pelo tenesmo constante, que foi reduzindo gradualmente. Os casos ilustram que a desarterialização hemorroidária transanal é factível quando realizada com anestesia local e sedação, visto que é segura e eficaz. Esta nova tecnologia pode também ser incorporada aos serviços cujo protocolo de anestesia local seja padrão.

Objetivo: Evaluar la seguridad de propofol combinado con meperidina y midazolam en colonoscopías, endoscopías y ecoendoscopía administrado por una enfermera supervisada por un gastroenterólogo entrenado y comparar su requerimiento en pacientes menores y mayores de 75 años. Material y métodos: Estudio descriptivo retrospectivo, que incluyó a pacientes mayores de 18 años de edad que recibieron propofol durante la endoscopía, colonoscopía (o endoscopía+colonoscopía) y ecoendoscopía. A los pacientes se les administró una dosis inicial de Meperidina (25 mg) y Midazolam (1-3 mg) por vía intravenosa (IV). Después de 2-3 minutos recibieron un bolo IV de propofol entre 10-30 mg. Se administraron bolos repetidos de 10-20 mg a intervalos no menores a 60 segundos durante cada procedimiento, titulado según necesidad y tolerancia del paciente. Resultados: Entre septiembre del 2006 y septiembre del 2016, se realizaron 9 704 procedimientos endoscópicos: 1 598 endoscopías, 3 065 colonoscopías, 2 492 endoscopía + colonoscopía y 57 eco-endoscopías. Hubo 3 912 mujeres (59,1%), la edad promedio fue de 57,1 ± 14,6 años, 880 pacientes (12,5%) mayores de 75 años. La dosis media de propofol para todos los procedimientos fue de 83,2 ± 48,1 mg, para la endoscopía y colonoscopía fue de 59,7 ± 36,2 mg y 77,2 ± 41 mg respectivamente. La dosis media utilizada en pacientes mayores de 75 años en endoscopía fue de 47,5 ± 37,8 mg, colonoscopías de 58,3 ± 33,4 mg y endoscopía + colonoscopía de 78,7 ± 42,7 mg en comparación con pacientes < 75 años en los que la dosis promedio de endoscopía fue de 61,1±35,8 mg (p <0,05), en colonoscopías de 80,5±41,3 mg (p<0,05) y en endoscopías+colonoscopías 105,9 ± 50,2 mg (p<0,05). No hubo complicaciones relacionadas con la sedación. Conclusiones: Propofol combinado con meperidina y midazolam en procedimientos endoscópicos, administrado por enfermera y dirigidos por un gastroenterólogo entrenado, es seguro. Los pacientes mayores de 75 años, necesitaron dosis significativamente menores de propofol para endoscopía, colonoscopia, endoscopía + colonoscopia y ecoendoscopía.
Objective: To evaluate safety of propofol combined with Meperidine and Midazolam in colonoscopies, upper endoscopies (EGD) and Endoscopic Ultrasound (EUS) administered by a nurse supervised by a trained gastroenterologist. To compare the required doses of propofol among older and younger than 75 years old. Materials and methods: Retrospective descriptive study including patients 18 years of age and older who received propofol for EGD, colonoscopy (or EGD + colonoscopy) and EUS. The patients were given a baseline dose of Meperidine (25 mg) and Midazolam (1-3 mg) intravenously (IV). After 2-3 minutes, they received an IV bolus of propofol between 10-30 mg. Repeat boluses of 10-20 mg were administered at intervals no lesser than 60 seconds during the procedure, as needed according to patient`s tolerance to the procedure. Results: Between September 2006 and September 2016, 9,704 procedures were performed, of which 1,598 were EGD, 3,065 colonoscopies, 2,492 EGD + colonoscopies and 57 EUS. There were 3,912 women (59.1%), and the average age was 57.1 ± 14.6 years. Eight hundred eighty (12.5%) were older than 75 years. The average dose of propofol for all the procedures was 83.2 ± 48.1 mg, for EGD and colonoscopy was 59.7 ± 36.2 mg and 77.2 ± 41 mg respectively. The average dose used in patients >75 years for EGD was 47.5 ± 37.8 mg, for colonoscopies 58.3 ± 33.4 mg and for EGD + colonoscopies was 78.7 ± 42.7 mg compared to patients <75 years in whom the average dose for EGD was 61.1 ± 35.8 mg (p<0.05), in colonoscopies was 80.5 ± 41.3 mg (p<0.05) and in EGD + colonoscopies 105.9 ± 50.2 mg (p<0.05). There were no sedation-related complications. Conclusions: Propofol combined with meperidine and midazolam in endoscopic procedures directed by a trained gastroenterologist is safe. Elderly patients (>75 years old) required significantly less doses of propofol for EGD, colonoscopy, EGD/colonoscopy and EUS.

BACKGROUND: Patients who undergo urinary catheterization may experience postoperative catheter-related bladder discomfort (CRBD). Previous studies have indicated that drugs with antimuscarinic effects could reduce the incidence and severity of CRBD. Accordingly, this study was carried out to investigate whether nefopam, a centrally acting analgesic with concomitant antimuscarinic effect, reduces the incidence and severity of CRBD. METHODS: Sixty patients with American Society of Anesthesiologists physical status I and II and aged 18–70 years who were scheduled to undergo elective ureteroscopic litholapaxy participated in this double-blinded study. Patients were divided into control and nefopam groups, comprising 30 patients each. In the nefopam group, 40 mg nefopam in 100 ml of 0.9% saline was administered intravenously. In the control group, only 100 ml of 0.9% saline was administered. All patients had a urethral catheter and ureter stent inserted during surgery. The incidence and severity of CRBD, numerical rating scale (NRS) score of postoperative pain, rescue pethidine dose, and side effects were recorded in the post-anesthesia care unit after surgery. RESULTS: The incidence (P = 0.020) and severity (P < 0.001) of CRBD were significantly different between the control group and the nefopam group. The NRS score of postoperative pain (P = 0.006) and rescue dose of pethidine (P < 0.001) were significantly higher in the control group than in the nefopam group. CONCLUSIONS: Intravenous administration of nefopam in patients scheduled to undergo ureteroscopic litholapaxy reduced the incidence and severity of CRBD, NRS score of postoperative pain and analgesic requirements.

Background: it was observed that a considerable proportion of patients undergoing surgery experience intraoperative and postoperative hypothermia and it was found that misregulation of body temperature due to anesthesia as well as the cold temperature of the operation room were the main cause
Purpose: to compare the anti-shivering effect of meperidine, hydrocortisone and granisetron after spinal anesthesia during elective cesarean section
Patients and Methods: this study presents a placebo-controlled prospective randomized blind study. Included patients were randomly [using computer generated randomization table] allocated into four equal groups each group consists of 28 patients
Results: in our study, age, sex, and ASA grade distribution of patients were nearly identical in the four groups. Furthermore, the duration of surgery and amount of irrigation fluid used in the four different groups were also similar. We did not observe a change in temperature gradient between the four groups. A study with a more prolonged duration of postoperative temperature monitoring is needed to note if core-periphery temperature changes occur with passage of time
Conclusion: the results indicate that IV granisetron 40 micro g/kg was effective as IV meperidine 0.4 mg/kg and both are slightly effective than IV hydrocortisone 2 mg/kg in reducing the incidence and intensity of shivering during spinal anesthesia compared to control group

Objetivou-se avaliar os efeitos da tranquilização com meperidina, acepromazina e de sua associação sobre os parâmetros ecocardiográficos em cães. Foram utilizados 12 cães adultos, da raça Rottweiler, submetidos ao exame ecocardiográfico sem utilização de sedação (controle - TC) e a três protocolos de tratamento, utilizando-se meperidina (TM), acepromazina (TA) e a associação dos medicamentos (TMA). As variáveis foram analisadas pelo teste de Tukey (P<0,05). Observou-se que as médias obtidas na onda A do fluxo mitral em TA e TMA diminuíram significativamente com relação ao TM, que não diferiu do TC. Houve uma diminuição significativa no valor de movimento anular mitral (MAM) e excursão sistólica do plano anular tricúspide (ESPAT) no TA. Não houve diferença significativa para os valores de fração de encurtamento (FE) entre TA e os demais tratamentos. Entretanto, observou-se que 57,3% dos cães apresentaram valores de FE abaixo da normalidade. As alterações encontradas podem ser decorrentes dos efeitos hipotensores da acepromazina utilizada de forma isolada. Conclui-se que a meperidina ou sua associação com acepromazina não alteram os parâmetros ecocardiográficos em cães saudáveis e que a acepromazina, utilizada isoladamente, causa alteração nos parâmetros de função sistólica dos cães, não sendo recomendada para a contenção química dos cães submetidos ao ecocardiograma, o que poderia levar à má interpretação do exame.(AU)
The aim of this study was to evaluate the effects of sedation with meperidine, acepromazine and its association on the echocardiographic parameters in dogs. Twelve adult Rottweilers were used and subjected to the echocardiography examination without the use of sedation (control - CT) and subjected to three treatment protocols using meperidine (MT), acepromazine (AT), and the combination of drugs (MAT). Variables were analyzed by Tukey test (p<0,05). The averages obtained in A-wave of mitral inflow in AT and MAT decreased significantly compared to MT, which did not differ from CT. There was a significant decrease in the measurement of mitral annulus motion (MAM) and tricuspid annular plane systolic excursion (TAPSE) at TA. There was no significant difference in shortening fraction (SF) values between TA and other treatments. However, it was observed that 57.3% of the dogs showed SF values below the normal range for the species. All changes found may be due to the hypotensive effects of acepromazine used in isolation. In conclusion, meperidine or its association with acepromazine does not alter echocardiographic parameters in healthy dogs and acepromazine, used alone, causes changes in the parameters of systolic function and is not recommended for sedation of dogs submitted to echocardiogram, since it could cause a misinterpretation of the exam.(AU)

BACKGROUND: Postoperative pain is a common, distressing symptom following arthroscopic knee surgery. The aim of this study was to compare the potential analgesic effect of dexmedetomidine after intrathecal versus intra-articular administration following arthroscopic knee surgery. METHODS: Ninety patients undergoing unilateral elective arthroscopic knee surgery were randomly assigned into three groups in a double-blind placebo controlled study. The intrathecal dexmedetomidine group (IT) received an intrathecal block with intrathecal dexmedetomidine, the intra-articular group (IA) received an intrathecal block and intra-articular dexmedetomidine, and the control group received an intrathecal block and intra-articular saline. The primary outcome of our study was postoperative pain as assessed by the visual analogue scale of pain (VAS). Secondary outcomes included the effect of dexmedetomidine on total postoperative analgesic use and time to the first analgesic request, hemodynamics, sedation, postoperative nausea and vomiting, patient satisfaction, and postoperative C-reactive protein (CRP) levels. RESULTS: Dexmedetomidine administration decreased pain scores for 4 h in both the intrathecal and intra-articular groups, compared to only 2 h in the control patient group. Furthermore, there was a significant reduction in pain scores for 6 h in the intra-articular group. The time to the first postoperative analgesia request was longer in the intra-articular group compared to the intrathecal and control groups. The total meperidine requirement was significantly lower in the intra-articular and intrathecal groups than in the control group. CONCLUSIONS: Both intrathecal and intra-articular dexmedetomidine enhanced postoperative analgesia after arthroscopic knee surgery. Less total meperidine was required with intra-articular administration to extend postoperative analgesia to 6 h with hemodynamic stability.

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: 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.

BACKGROUND: Dexamethasone has a prophylactic effect on postoperative nausea and vomiting (PONV) and perioperative hydration is believed to play a role in PONV prophylaxis. This study was performed to examine the combined effects of pre-induction dexamethasone plus super-hydration on PONV and pain following laparoscopic cholecystectomy (LC). METHODS: A total of 100 female patients undergoing LC were enrolled and randomized equally into two groups. Group DF received 5 mg dexamethasone (pre-induction) plus 30 ml/kg Ringer's lactate (intraoperative) and group D received 5 mg dexamethasone (pre-induction) alone. Anesthetic and surgical managements were standardized for all patients. The incidence and severity of PONV, and intra and post-operative analgesic and postoperative antiemetic consumption, were assessed during the first 24 h postoperatively. Post-anesthesia care unit (PACU) stay and aggregated 24 h pain scores were calculated. RESULTS: Group DF had significantly lower PONV than group D (P = 0.03). The number of patients with the lowest PONV score was significantly increased in group DF (P = 0.03). Ondansetron consumption was significantly lower in group DF (P < 0.0001). The mean accumulated 24 h pain scores were significantly lower in group DF compared to group D (P < 0.0001). The time to first analgesic request was significantly longer in group DF than group D (P < 0.0001). In addition, total meperidine consumption during the first postoperative 24 h was significantly lower in group DF than group D (P = 0.002). CONCLUSIONS: In female patients undergoing LC, pre-induction with 5 mg dexamethasone plus intraoperative 30 ml/kg Ringer's lactate solution decreased PONV and pain during the first 24 h postoperatively compared to 5 mg dexamethasone alone.

BACKGROUND: Gabapentin and pregabalin are antiepileptic drugs that are also used for chronic pain treatment. This study evaluated the effects of pregabalin and gabapentin on postoperative pain in patients undergoing laparoscopic cholecystectomy. METHODS: A total of 108 candidates for elective laparoscopic cholecystectomy were randomly assigned to gabapentin (n = 36), pregabalin (n = 36), and placebo (n = 36) groups. Patients received 800 mg of gabapentin or 150 mg of pregabalin orally one hour before surgery. Postoperative analgesia was administered by pethidine via patient-controlled analgesia. The amount of opioid consumed, number of nausea events, vomiting, and pain scores at 2, 6, 12, and 24 hours after surgery were recorded. RESULTS: The gabapentin and pregabalin groups had significantly lower pain intensity than the placebo group, and pain intensity in the pregabalin group decreased more compared to the gabapentin group. The mean amount of pethidine consumption in the placebo group was significantly higher than in the gabapentin and pregabalin groups. CONCLUSIONS: A single dose of gabapentin or pregabalin decreased postoperative pain and nausea, as well as vomiting and opioid consumption after laparoscopic cholecystectomy. Moreover, the findings revealed that pregabalin was superior to gabapentin for reducing postoperative pain.
