RESUMO

STUDY OBJECTIVE: To assess clinical performance, bleeding pattern, dysmenorrhea, and satisfaction up to 1 year after placement of 3 types of intrauterine devices (IUDs) (TCu380A, levonorgestrel 52 mg, and levonorgestrel 19.5 mg) in adolescents METHODS: The study was a randomized trial with 318 adolescents allocated to the 3 IUDs. We assessed reasons for removal, continuation, menstrual patterns, dysmenorrhea, and satisfaction. RESULTS: Participants aged (mean ± SD) 17.9 ± 1.4 years, with 80.8% being nulligravidae. After 1 year, 265 (83.3%) continued using the IUD; however, the continuation rate of TCu380A (75.4 ± 4.2) was lower than that of both the levonorgestrel 52-mg (88.6 ± 3.1) and 19.5-mg IUDs (86.8 ± 3.3), and bleeding/pain and expulsion were the main reasons for removal of the TCu380A IUD. The duration of menstruation was longer among the TCu380A IUD users (6.0 ± 2.0 days) than those using the levonorgestrel 52 mg (2.5 ± 3.9) and 19.5 mg (3.2 ± 3.2) devices, P < .001. Amenorrhea was reported by 49.5% and 37.8% users of the levonorgestrel 52-mg and 19.5-mg devices, respectively, P < .001. Dysmenorrhea was reported in 68.5% of all participants at the baseline; this was 67.9% of the TCu380A group and 33.3% and 36.0% of the levonorgestrel 52-mg and 19.5-mg IUD groups, respectively, P < .001. Satisfaction ranged from 80.7% in the TCu380A group to 97.8% in the levonorgestrel 52-mg group (P = .03). CONCLUSION: The 3 IUDs are suitable for adolescents, with high contraceptive efficacies and rates of continuation within 1 year of use and high degrees of satisfaction. Users of the hormonal IUDs reported lower expulsion rates, more favorable menstrual patterns, and less dysmenorrhea compared with the TCu380A IUD.

RESUMO

OBJECTIVE: To compare the continuation rates, expulsion, and other reasons for discontinuation of the hormonal intrauterine device with 52 mg of levonorgestrel (52 mg LNG-IUD) in adolescents and adult women. METHODS: We conducted a retrospective cohort study that included 393 women in whom we placed a 52 mg LNG-IUD and followed up to 5 years. We created two retrospective cohorts, one with 131 adolescents (aged between 12 and 19 years) and the other with 262 women aged ≥20 years. Each adolescent was paired with two adult women who had the same parity and who had a 52 mg LNG-IUD inserted on the same day. We used the Mann-Whitney test to compare numerical variables in both groups, the Kaplan-Meier method, and the log-rank test to compare the continuation, expulsion and other reasons for IUD discontinuation of the two groups. RESULTS: Age of the adolescents and adult women were mean ± SD 18.1 (±1.1) and 31 (±6.8) years, respectively (p = 0.015). Continuation rates by the fifth year of use were 55.6/100 women-years (W-Y) and 70.3/100 W-Y among adolescents and adult women (p = 0.106); and expulsion rates were 8.4/100 and 6.0/100 W-Y, respectively (p = 0.463). Adolescents had a lower continuation rate during 3 to 5 years of follow-up (p = 0.011) and a high rate of removals due to bleeding/pain (18.5 ± 5.7/100 W-Y vs 6.4/100 ± 2.1 W-Y, p = 0.039). CONCLUSION: Adolescents who used the 52 mg LNG-IUD showed a lower continuation rate 3-5 years after device placement than adult women. The expulsion rates were similar in both groups.

Adolescents who used the 52 mg LNG-IUD showed expulsion rates similar than adult women. Despite the good continuation rate, adolescents had a lower continuation rate within 3­5 years of follow-up and high rate of removals due to bleeding/pain than adult users.

RESUMO

Este artículo profundiza en el conocimiento de las mujeres habitantes de la calle de las cinco ciudades más densas del país, teniendo como telón de fondo las relaciones patriarcales de desigualdad que permean los diferentes momentos de la habitanza de la calle empezando por la decisión de salir a vivir en esta. Con la información disponible de los censos de habitantes de la calle de 2017 y 2019 realizados por el Departamento Administrativo Nacional de Estadística (DANE) en Bogotá, Medellín, Cali, Barranquilla y Bucaramanga, indaga las diversas formas femeninas de habitar la calle y las condiciones en que esta se lleva a cabo. Apunta básicamente a eliminar la masculinización de la habitanza de la calle, visibilizando la presencia de mujeres diversas en ciclos de vida y con vivencias expulsoras antes y de hábitos de subsistencia y manutención durante su permanencia en la calle.

This article delves into the knowledge of women living on the streets of the five densest cities in the country, taking as a background the patriarchal relations of inequality that permeate the different moments of street life starting with the decision to go out to live in this. With the information available from the censuses of street dwellers of 2017 and 2019 carried out by DANE in Bogotá, Medellín, Cali, Barranquilla and Bucaramanga, it investigates the various female ways of inhabiting the street and the conditions in which it is carried out. It basically aims to eliminate the masculinization of street living, making visible the presence of diverse women in life cycles and with expeller experiences before and of subsistence and maintenance habits during their stay on the street.

RESUMO

Abstract Objective To evaluate the expulsion and continuation rates of the copper intrauterine device (IUD) inserted in the immediate postpartum period in a Brazilian public university hospital. Materials and Methods In the present cohort study, we included women who received immediate postpartum IUD at vaginal delivery or cesarean s March 2018 to December 2019. Clinical data and the findings of transvaginal ultrasound (US) scans performed 6-weeks postpartum were collected. The expulsion and continuation rates were assessed 6-months postpartum using data from the electronic medical records or by telephone contact. The primary outcome was the proportion of IUDs expelled at 6 months. For the statistical analysis, we used the Student t-test, the Poisson distribution, and the Chi-squared test. Results There were 3,728 births in the period, and 352 IUD insertions were performed, totaling a rate of 9.4%. At 6 weeks postpartum, the IUD was properly positioned in 65.1% of the cases, in 10.8% there was partial expulsion, and in 8.5% it had been completely expelled. At 6 months postpartum, information was obtained from 234 women, 74.4% of whom used IUD, with an overall expulsion rate of 25.6%. The expulsion rate was higher after vaginal delivery when compared with cesarean section (68.4% versus 31.6% respectively; p = 0.031). There were no differences in terms of age, parity, gestational age, final body mass index, and newborn weight. Conclusion Despite the low insertion rate of copper IUDs in the postpartum period and a higher expulsion rate, the rate of long-term continuation of intrauterine contraception was high, indicating that it is a useful intervention to prevent unwanted pregnancies and to reduce short-interval birth.

Resumo Objetivo Avaliar as taxas de expulsão e continuação do dispositivo intrauterino (DIU) de cobre inserido no pós-parto imediato em um hospital universitário brasileiro. Materiais e Métodos Neste estudo de corte transversal, foram incluídas parturientes submetidas à inserção de DIU de cobre no pós-parto imediato entre março de 2018 e dezembro de 2019. Foram coletados dados clínicos e da ultrassonografia (US) transvaginal realizada após seis semanas. As taxas de expulsão e de continuação foram avaliadas após seis meses por meio de dados do prontuário ou por contato telefônico. O resultado principal foi a proporção de DIUs expelidos em seis meses. Para análise estatística, utilizaram-se o teste t de Student, a distribuição de Poisson, e o teste do Qui quadrado. Resultados Houve 3,728 nascimentos no período, e foram inseridos 352 DIUs, em uma taxa de 9,4%. Com 6 semanas, o DIU estava bem posicionado em 65,1% dos casos, em 10,8%, houve expulsão parcial, e, em 8,5%, fora totalmente expelido. Aos 6 meses de pós-parto, foram obtidas informações de 234 mulheres, 74,4% das quais usavam DIU, com uma taxa de expulsão geral de 25,6%. A taxa de expulsão foi maior após o parto vaginal do que após cesariana (68,4% versus 31,6%, respectivamente; p = 0,031). Não houve diferenças quanto à idade, paridade, idade gestacional, índice de massa corpórea final, e peso do recém-nascido. Conclusão Apesar da baixa taxa de inserção e alta taxa de expulsão, a taxa de continuação em longo prazo da contracepção intrauterina com DIU de cobre foi elevada, o que indica que se trata de intervenção útil para prevenir gestações indesejadas em curto intervalo de tempo.

RESUMO

Resumen Introducción: En los pacientes con DCPT, la disfunción ventricular es inevitable, y más temprana en VU derechos. La deformación miocárdica por STE y RMC-FT parece promisoria. Objetivo: Analizar la función ventricular mediante STE y RMC-FT en pacientes con DCPT, en comparación con RMC convencional según la morfología del VU y la posible implicación en su diagnóstico temprano. Método: Se recogieron medidas del strain longitudinal y circunferencial por STE y RMC-FT, volúmenes ventriculares y FE por RMC en 64 pacientes con DCPT. Resultados: La morfología ventricular no se relacionó con disfunción por RMC. Los VU derechos tuvieron valores por STE y RMC-FT disminuidos respecto de los VU izquierdos, con FE similares. Existe correlación entre STE y RMC-FT, no equivalentes, con buena factibilidad y reproducibilidad. Conclusiones: La RMC-FT y el STE son técnicas útiles en el diagnóstico temprano y la vigilancia de la función ventricular en VU derechos con FE preservada.

Abstract Introduction: In patients with TCPC, the development of ventricular dysfunction is inevitable and is more precocious in SRVs. Myocardial deformation by STE and CMR-FT is promising. Objective: To analize ventricular function in patients with TCPC using STE and CMR-FT compared with conventional cMRI, depending on SV morphology, to determine their role in early diagnosis of ventricular dysfunction. Method: Sixty-four patients with TCPC were included. Longitudinal and circumferential strain by STE and CMR-FT and ventricular volume and EF were obtained. Results: Dysfunction analyzed by cMRI showed no association with ventricular morphology. SRVs had lower values in STE and CMR-FT compared with SLVs, with similar EF. While not equivalent, correlation was observed between the STE and the CMR-FT values, demonstrating good feasibility and reproducibility. Conclusion: The strain data in CMR-FT and STE could be useful for diagnosis and monitoring of ventricular function and as markers of early SRV dysfunction with preserved EF.

RESUMO

OBJECTIVE: To compare the expulsion and continuation rates of the levonorgestrel (LNG) 52 mg intrauterine system (IUS) in a cohort of nulligravid and parous users. METHODS: We conducted a retrospective cohort study that included 996 participants in whom we placed an LNG-IUS, and the participants were monitored for up to 5 years after device placement. We identify 498 nulligravid participants in the medical record database between 2012 and 2020. Each nulligravida was paired with a parous users who had an LNG-IUS inserted on the same day, just before or after the nulligravida. The Kaplan-Meier method and the log-rank test were used to compare the survival curves of the two groups. RESULTS: By the fifth year of use, the expulsion rates were 7.6/100 and 8.2/100 women-years (W-Ys) and the continuation rates were 641/100 W-Ys and 65.4/100 W-Ys without difference among nulligravid and parous users, respectively (P = 0.782 and P = 0.564, respectively). We observed 29 and 31 expulsions among nulligravid and parous users, respectively. CONCLUSION: Nulligravid and parous participants who used the 52 mg LNG-IUS showed similar expulsion and continuation rates during five years of use.

RESUMO

OBJECTIVE: To compare the expulsion rates of the levonorgestrel (LNG) 52 mg intrauterine system (IUS) among women with heavy menstrual bleeding versus women using solely for contraception. STUDY DESIGN: We conducted an audit study of 548 (8.8%) women with heavy menstrual bleeding and 5655 (91.2%) users for contraception (comparison group) for 4 years in Campinas, Brazil. We retrieved sociodemographic data, expulsion rates, and variables associated to device placement. Among women with heavy menstrual bleeding, we placed the devices after the cessation of bleeding or after the reduction of menstrual flow. RESULTS: Thirty-one of 548 (5.6%) women with heavy menstrual bleeding and 315 of 5655 (5.6%) from the comparison group expelled the device. This constituted 7.8 expulsions/100 women-years in women with heavy menstrual bleeding and 10.3 expulsions/100 women-years from the comparison group (p = 0.94). Expulsion risk was associated with previous cesarean delivery in both groups (OR 1.93, 95% CI 1.36;2.74). CONCLUSIONS: Expulsion rates of the LNG IUS among women with heavy menstrual bleeding whose IUS was placed after the cessation or reduction of bleeding were similar to expulsion rates among users for contraception. Previous cesarean delivery was a risk factor for expulsion. IMPLICATIONS: We recommend the 52 mg LNG IUS placement after the cessation of bleeding or a reduction of menstrual flow among women with heavy menstrual bleeding because this strategy was associated with similar risk of expulsion when compared to users for contraception.

RESUMO

OBJECTIVE: To identify clinical and demographic factors associated with missing strings and expulsion after postplacental insertion of copper T380A intrauterine devices (TCu380A IUD). METHODS: This is a secondary analysis of an implementation study. We followed participants who had a postplacental TCu380A IUD insertion, at two postpartum visits: 45-90 days (visit 1) and 6-9 months (visit 2). We used multiple log-binomial regression models to evaluate the demographic and clinical variables associated with missing strings and with IUD expulsion. RESULTS: We included 705 participants who had a postplacental IUD insertion. We observed missing strings in 275 (47.9%) participants at visit 1, and in 127 (34.2%) participants at visit 2. We identified 61 expulsions (8.9%) by visit 2. In the multiple regression models, only the delivery type was associated with missing strings and expulsion. Compared with vaginal delivery, cesarean delivery increased the risk of missing strings (adjusted relative risk [aRR] 6.21; 95% confidence interval [CI] 4.29-8.99) but reduced the risk of IUD expulsion (aRR 0.24; 95% CI 0.13-0.43). CONCLUSION: The delivery mode was the only factor associated with missing strings and expulsion after postplacental IUD insertion. Cesarean section was associated with an increased risk of missing strings but decreased risk of expulsion after postplacental TCu380A IUD insertion.

RESUMO

Resumen La anisakidosis es una zoonosis parasitaria accidental y cosmopolita de los seres humanos, siendo su hospedero definitivo los mamíferos marinos como lobos de mar, focas y delfines, entre otros. El ser humano se infecta por el consumo en estado larvario del nemátodo de la familia Anisakidae presentes en pescados y mariscos crudos como la merluza o el congrio. Los helmintos se ubican preferentemente en el tubo digestivo alto, observándose la regurgitación del parásito a la boca o evidenciándose durante la realización de una endoscopía digestiva alta. En forma infrecuente las larvas pueden migrar al peritoneo o seguir su paso por el intestino delgado y colon, siendo inhabitual la expulsión por las deposiciones. Presentamos el caso de una expulsión dos larvas L3 de la familia Anisakidae en deposiciones.

Abstract Anisakidosis is an accidental and cosmopolitan parasitic zoonosis of human beings, its definitive host being marine mammals such as sea lions, seals and dolphins, among others. Humans are infested by consumption in the larval stage of the nematode of Anisakis present in raw fish and shellfish such as hake or conger eel. The infestation is preferably located in the upper digestive tract, observing the regurgitation of the parasite to the mouth or becoming evident during an upper gastrointestinal endoscopy. In rare cases, the larvae can migrate to the peritoneum or continue their passage through the small intestine and colon, with expulsion in stools being unusual. We present a case of expulsion of two larvae of the Anisakidae family in feces.

RESUMO

Introducción y objetivos: La insuficiencia valvular mitral provoca el vaciado simultáneo hacia la aorta y la aurícula izquierda durante la sístole ventricular, lo que produce una disminución del volumen hacia la circulación sistémica. En este estudio se busca obtener un dato preciso del porcentaje de volumen expulsado en sentido anterógrado en pacientes con insuficiencia mitral. Métodos: Se aplica una fórmula ecocardiográfica de "corrección" de la fracción de expulsión del ventrículo izquierdo (FEVI) en 114 pacientes con insuficiencia mitral, con base en la medición de la fracción regurgitante. Resultados: La corrección de la FEVI demostró que el 44.7% de los casos (n = 51) debe reclasificarse en cuanto a la calidad de su función sistólica ventricular izquierda. De 79 sujetos con FEVI normal (≥ 50%) sólo se mantuvieron 32 en la misma categoría; en el grupo con FEVI moderadamente reducida (intervalo intermedio, 40-49.9%) se pasó de 6 a 23 casos y, en aquéllos con FEVI reducida (< 40%), el grupo aumentó de 29 a 59; el subgrupo de pacientes con FEVI < 30% se incrementó de 21 a 41 sujetos. Conclusiones: Puesto que en la mayoría de las guías de tratamiento la FEVI se usa para estratificar riesgos e indicaciones terapéuticas, los autores creen que la ponderación de la insuficiencia mitral puede incrementar la precisión del tratamiento y la posibilidad de incluir a pacientes que no están considerados en esos tratamientos en el momento actual. Introduction and objectives: Mitral valve regurgitation causes simultaneous emptying to the aorta and left atrium during ventricular systole, generating a decrease in volume supply to the systemic circulation. In this study we seek to obtain an accurate data on the percentage of volume expelled in the anterograde direction in patients with mitral regurgitation. Methods: An echocardiographic formula for "correction" of the left ventricular ejection fraction (LVEF) was applied in 114 patients with mitral regurgitation, based on the measurement of the regurgitant fraction. Results: Correction of the LVEF showed that 44.7% of cases (n = 51) should be reclassified in terms of the quality of their left ventricular systolic function. Of 79 subjects with normal LVEF (≥ 50%) only 32 remained in the same category; in the group with moderately reduced LVEF (medium range, 40-49.9%) it went from 6 to 23 cases and, in those with reduced LVEF (< 40%), the group increased from 29 to 59; the subgroup of patients with LVEF < 30% increased from 21 to 41 subjects. Conclusions: Given that in most treatment guidelines LVEF is used to stratify risks and therapeutic indications, the authors believe that the weighting of mitral regurgitation can increase the accuracy of treatment, and the possibility of including patients who, at this current moment, are not considered for these therapies.

RESUMO

Uterine leiomyomas are benign tumors that develop from smooth muscle tissue and are present in up to 77% of women in menacme. They are often asymptomatic but can cause pelvic pain, compression, abnormal uterine bleeding, and degeneration. We present the first case report of a perimenopausal woman who exhibited complete and spontaneous expulsion of uterine fibroids without embolization or use of medication. She complained of a mass extruding from the vaginal orifice associated with bleeding and pain for a couple of hours. The anatomopathological findings showed a myomatous lesion. Complete expulsion of a uterine fibroid is a rare condition that may be associated with profuse hemorrhage and can pose a risk to the patient. When it occurs during perimenopause, it can mimic several clinical conditions. Therefore, gynecologists must remain alert to make the correct diagnosis and treatment.

RESUMO

Objective: To evaluate the rate of expulsion of intrauterine device (IUD) inserted during the immediate and mediate puerperium. To evaluate whether the type of delivery is a predictor of expulsion of the IUD when inserted in the puerperium period. Material and Methods: This was a prospective observational study. Patients whose IUD (TCU-380 copper) was placed during the puerperal period were divided in two groups according to the time of placement: immediate and mediate puerperium. The decision regarding the time of IUD insertion was made in a non-randomized manner. Analysis was performed using chi-square, Mann-Whitney U, and Spearman's correlation tests and logistic regression analysis. Results: The total rate of IUD expulsions was 28.8% (49/170). There was no significant association between the occurrence of expulsion and the timing of IUD insertion (immediate vs mediate puerperium; 26.6% vs 34.78%, p=0.296). Among patients experiencing expulsion, 79.6% (39/49) underwent insertion after vaginal delivery and 20.4% (10/49) during cesarean section (CS). The type of delivery was a significant predictor for IUD expulsion (p<0.0001). Vaginal delivery was fourfold more likely to be associated with IUD expulsion inserted in the puerperal period than CS (odds ratio: 4.23, 95% confidence interval: 1.94-9.25). There was no significant correlation between the period between IUD insertion and the diagnosis of expulsion in regard to number of pregnancies (r=-0.160, p=0.271) or gestational age at delivery (r=-0.058, p=0.939). Conclusion: Vaginal delivery was the most prevalent type of delivery in patients who underwent IUD insertion during the immediate and mediate puerperium. The risk of IUD expulsion after vaginal delivery was greater than CS.

RESUMO

Heart failure is a global public health problem, with more than 37 million patients living with heart failure around the world. Heart failure with preserved ejection fraction is an increasingly common category (approximately 60% of the cases) and shows remarkable differences in diagnosis and treatment when compared with heart failure with reduced ejection fraction. The current review covers epidemiology, risk factors, pathophysiologic mechanisms, clinical and paraclinical characteristics and diagnostic criteria of heart failure with preserved ejection fraction and concludes with a plea for original research in our country.

RESUMO

The aim of this study was to evaluate the larval expulsion, larvicidal effect, retention rate of dead larvae and overall efficacy of sarolaner on the treatment of myiasis caused by New World screwworm Cochliomyia hominivorax in naturally infested dogs. Eight Beagle dogs received a single dose of saroalner 40 mg, with dosage ranging from 2.7 mg/kg to 3.7 mg/kg. Evaluations occurred every 15 min in the first hour, every hour for up to 6 h, and after 24 h of treatment. At 24 h post-treatment, total wound cleaning was performed, including removal and counting of remaining live and dead larvae. The animals received antibiotic, analgesic and wound cleaning support until complete wound healing. The average expulsion of the larvae was 50.9 % occurring mainly after 4 h of treatment. The larvicidal effect was 70.6 % at 6 h after treatment and 100 % at 24 h. The mean retention rate of dead larvae of sarolaner was 33.9 %, The overall efficacy was 100 %, thus making sarolaner an excellent treatment option in myiasis caused by C. hominivorax larvae in dogs.

RESUMO

RESUMEN La fracción de expulsión del ventrículo izquierdo es una medición clave para la valoración de su función sistólica. En caso de insuficiencia valvular mitral, parte del volumen eyectado se regurgita hacia el atrio izquierdo, el volumen anterógrado es menor que el supuesto y la fracción de expulsión se mantiene en un valor que no representa adecuadamente el estado inotrópico. Esto no permite que ciertos pacientes con falla cardíaca puedan ser correctamente clasificados y tratados, en especial en cuanto se refiere a la indicación de dispositivos (terapia de resincronización, implante de desfibriladores). Tomando como base el cálculo de la fracción regurgitante se propone una sencilla fórmula para hacer una "corrección" de la fracción de expulsión en este tipo de casos y se puso a prueba en un grupo de pacientes ambulatorios citados consecutivamente. Se confirma que en un 54% de pacientes se ven modificados su pronóstico, su tratamiento o ambos al aplicarse la fórmula propuesta.

ABSTRACT Left ventricular ejection fraction is a key measurement for the assessment of systolic function. In case of mitral valve insufficiency, part of the ejected volume regurgitates to the left atrium, the anterograde volume is less than expected, and the ejection fraction maintains a value that does not adequately represent the inotropic state. This does not allow certain patients with heart failure to be correctly classified and treated, especially regarding the indication of devices (resynchronization therapy and defibrillator implant). Based on the calculation of the regurgitant fraction, we propose a simple formula to make a "correction" of the ejection fraction in this type of cases. The corrected ejection fraction was tested in a group of consecutive outpatients. The study confirmed that 54% of patients have their prognosis and/or treatment modified when applying the proposed formula.

RESUMO

OBJECTIVES: In some settings women are advised to return to the clinic after intrauterine contraceptive (IUC) placement, for a follow-up visit to check the strings and identify any expulsions. Our objective was to evaluate whether the number of follow-up visits to check the strings at the external cervical os after IUC placement predicts or prevents future expulsions. METHODS: This was a retrospective study conducted at the University of Campinas Medical School, Brazil. We reviewed the medical records of all women who used an IUC between January 1980 and December 2017, to identify women who had experienced IUC expulsion (N = 1974). We excluded women whose IUC was expelled more than once (n = 331) or after 10 years of use (n = 31). We fitted a generalised linear model of the time between IUC placement and expulsion, adjusting for several variables at expulsion. Significance was established at p < .05. RESULTS: Most expulsions (843/1612; 52.3%) occurred within the first 6 months after IUC placement and 691/1612 (42.9%) were within the first three months after placement. The adjusted model showed that the number of visits, the woman's age, and complaints of pain and bleeding during use were not significantly associated with and had no influence on expulsion. CONCLUSIONS: Our results indicate that after IUC insertion more than one follow-up visit within the first four to six months after placement is not necessary, as additional visits to check for IUC strings do not appear to reduce or predict future expulsion.

RESUMO

Resumen OBJETIVO: Determinar la permanencia del dispositivo intrauterino TCu 380A insertado después de algún procedimiento obstétrico efectuado a pacientes atendidas en el Hospital General Dr. Aurelio Valdivieso. MATERIAL Y MÉTODOS: Estudio transversal y descriptivo efectuado en pacientes que concluyeron el embarazo entre el 1 de octubre de 2016 y el 31 de marzo de 2017, en el Hospital General Dr. Aurelio Valdivieso y que aceptaron se les colocara el dispositivo intrauterino TCu 380A después de algún procedimiento obstétrico y antes de darlas de alta del hospital. Variables de estudio: cantidad de embarazos, terminación de estos, médico responsable de la colocación, técnica y permanencia. El análisis estadístico implementado fue el univariado. RESULTADOS: Se incluyeron 182 pacientes con media de edad de 23 años y límites de 14 y 43 años. En el seguimiento de la permanencia del dispositivo 42.3% (n = 77) se encontró in situ, 28.5% (n = 52) en mala posición, y 0.55% (n = 1) lo expulsó. CONCLUSIONES: La permanencia del dispositivo intrauterino parece tener una relación estrecha con la forma correcta de insertarlo y, desde luego, con la experiencia acumulada del médico. En las primeras inserciones el médico debe ser supervisado por otro de mayor experiencia o, simplemente, con la vigilancia de los médicos adscritos.

Abstract OBJECTIVE: To determine the permanence of the TCu 380A IUD inserted after the obstetric event in the Dr. Aurelio Valdivieso Hospital. MATERIAL AND METHODS: Cross-sectional and descriptive study carried out in patients who concluded their pregnancy, between October 1, 2016 and March 31, 2017, at the Dr. Aurelio Valdivieso General Hospital (Oaxaca, Mexico) and who accepted the placement of the TCu 380A intrauterine device during the postpartum period. and before discharge from the hospital. Study variables: number of pregnancies, termination of these, doctor responsible for the placement, technique and permanence. The statistical analysis implemented was univariate. RESULTS: The study was conducted in 182 patients with a mean age of 23 years, a minimum of 14 years and a maximum of 43 years. In the monitoring of the permanence of the IUD TCu 380A with 42.31% (77) was found in situ, 28.57% (52) in poor position, and 0.55% (1) was expelled. CONCLUSIONS: The permanence of the intrauterine device seems to have a close relationship with the correct way to insert it and, of course, with the accumulated experience of the doctor. In the first insertions the doctor must be supervised by another one of greater experience or, simply, with the surveillance of the assigned doctors.
