Prevalence and intensity of pain during diagnostic hysteroscopy in women attending an infertility clinic: analysis of 489 cases / Prevalência e intensidade da dor na histeroscopia diagnóstica em mulheres atendidas em uma clínica de infertilidade: análise de 489 casos

ABSTRACT Objective To investigate the prevalence and intensity of pain perception during diagnostic hysteroscopy in women and potential related factors. Methods A total of 489 women were investigated at an infertility clinic. Fluid diagnostic hysteroscopy was performed without analgesia or anesthesia by gynecologists with different levels of experience in operative hysteroscopy, using a 2.9mm rigid scope. The Visual Analog Scale was used to score pain intensity after vaginal speculum insertion and after hysteroscopy. Data collected included age, ethnicity, body mass index, history of infertility and endometrial surgery (curettage and/or hysteroscopy), smoking habits, and hysteroscopy diagnosis. Only the state of anxiety was assessed by the State-Trait Anxiety Inventory given to each patient before the procedure. Results Hysteroscopy median (25th to 75th) Visual Analog Scale scored 3.3 (3 to 5), and 41.7% of the women referred Visual Analog Scale score ≥4. Median (25th to 75th) State-Trait Anxiety Inventory score was 42 (38 to 45), and 58.3% of the women referred State-Trait Anxiety Inventory score >40. Hysteroscopy Visual Analog Scale score was significantly correlated to surgeon experience and to vaginal speculum insertion but not to State-Trait Anxiety Inventory score, ethnicity or abnormal hysteroscopic findings. Conclusion Diagnostic hysteroscopy was mostly perceived as a mild discomfort procedure by most women. Nevertheless, in a considerable number of cases, women perceived hysteroscopy as painful. Pain perception was linked to individual pain threshold and surgeon experience, but not to pre-procedural anxiety state levels, ethnicity or abnormal hysteroscopic findings.

RESUMO Objetivo Investigar a prevalência e a intensidade da percepção da dor durante a histeroscopia diagnóstica, bem como os possíveis fatores relacionados. Métodos Foram incluídas 489 mulheres submetidas à propedêutica de infertilidade. A histeroscopia diagnóstica foi realizada sem analgesia ou anestesia, por ginecologistas com níveis de experiência diferentes em histeroscopia, usando histeroscópio rígido de 2,9mm. A Escala Visual Analógica foi utilizada para avaliar a intensidade da dor após a inserção do espéculo vaginal e após a histeroscopia. Os dados coletados incluíram idade, etnia, índice de massa corporal, história de infertilidade e cirurgia endometrial (curetagem e/ou histeroscopia), tabagismo e histeroscopia diagnóstica. Avaliou-se apenas o estado de ansiedade pelo Inventário de Ansiedade Traço-Estado de cada paciente antes do procedimento. Resultados A mediana (25ºa 75º) de histeroscopia pela Escala Visual Analógica foi 3,3 (3 a 5), e 41,7% das mulheres obtiveram pontuação ≥4. A mediana (25ºa 75º) do Inventário de Ansiedade Traço-Estado foi 42 (38 a 45), e 58,3% das mulheres referiram pontuação >40. A pontuação da Escala Visual Analógica da histeroscopia apresentou correlação estatisticamente significante com a experiência do cirurgião e a inserção do espéculo vaginal, mas não a pontuação do Inventário de Ansiedade Traço-Estado, etnia ou achados histeroscópicos anormais. Conclusão A histeroscopia diagnóstica foi percebida pela maioria das mulheres como desconforto leve, mas um número considerável de pacientes classificou o procedimento como doloroso. A percepção da dor esteve ligada ao limiar individual e à experiência do cirurgião, mas não aos níveis de ansiedade pré-procedimento, à etnia e nem aos achados histeroscópicos anormais.

Predicting intraoperative pain in emergency endodontic patients: clinical study

Abstract This prospective observational study sought to investigate the incidence of intraoperative pain (IOP) among emergency endodontic patients and to construct an IOP prediction model that includes preoperative pain level (PPL). All patients who underwent emergency endodontic treatment at Gazi University, Ankara, Turkey, during the spring term of 2016 were considered for inclusion in the study. Demographic and clinical variables and PPL were recorded. Local anesthesia was provided to all patients before beginning routine endodontic treatment. IOP was defined as the condition of requiring supplementary anesthesia before the working length was established and exhibiting persistent moderate or severe pain despite supplementary anesthesia. Data from 85% and 15% of 435 patients (178 men, 257 women; mean age: 35 years) were used to develop predictive models by multiple logistic regression analysis and to test external validity of the models, respectively. Two multiple logistic regression models achieved good model fits. Model 1 included age, pulpal diagnosis, and arc (p < 0.05). In addition to these variables, Model 2 included periapical diagnosis and PPL (p < 0.15). Models 1 and 2 showed accuracies of 0.76 and 0.75, sensitivities of 0.74 and 0.77, and specificities of 0.76 and 0.74, respectively for the modeling data (internal validity), and accuracies of 0.82 and 0.80, sensitivities of 0.83 and 0.67, and specificities of 0.81 and 0.81, respectively for the control data (external validity). The IOP incidence was 10.3%. IOP in patients undergoing emergency endodontic treatment can be successfully predicted by using models that account for demographic and clinical variables, including PPL.
