Anxiety in dental surgery may lead to behavioral and physiological changes for the patient and constitute a frequent challenge for the oral surgeon. The objective of this study was to compare the effect of inhalatory nitrous oxide and oxygen (N 2 O/O 2) with oral diazepam conscious sedation in vital signs of patients undergone third molar extraction. Outpatients who needed removal of partially impacted, bilateral lower third molars, during the period of one year, were included. Each patient underwent conscious sedation with either oral diazepam or inhalatory N 2 O/O 2 on a randomized controlled trial, split-mouth design. Systolic and diastolic blood pressure, heart rate and oxygen blood saturation were the changes measured before, at the beginning and the end of the procedure. Also, surgical procedure duration was recorded. Data from vital signs were submitted to analysis of variance and the duration of the surgery to paired Student's t-test. Twenty-five healthy outpatients (13 women and 12 men) with a mean age of 21.6 years were studied. There was an increase in systolic and diastolic pressure and in heart rate in the beginning; these values decreased and stabilized at the end of the surgical procedure in both treatments (p < 0.001) being lower in N 2 O/O 2 but without difference between treatments. The surgical procedure duration was lower and occurred an expected increase of oximetry under N 2 O/O 2 sedation (p < 0.001). Both treatments were effective for the conscious sedation but N 2 O/O 2 showed better outcomes, mainly in duration of the surgery.

O presente artigo discute como a temática do “medo” é abordada em cinco obras de literatura infantil contemporâneas. Busca-se compreender como as concepções sobre o medo alteraram ao longo da história, assim como analisar como ele vem sendo retratado na contemporaneidade, visto que temas antes tidos como “tabus” passam a ser discutidos na infância, de modo especial a partir da literatura. Para isso, foram selecionados cinco livros híbridos, que mesclam diferentes linguagens, assim como foram utilizados alguns autores fundantes, tais como Canclini (2008), Amarilha (2000) e Storch (2016). Como resultado das análises foi possível notar que as obras infantis contemporâneas vêm cada vez mais trazendo um olhar atento a temáticas antes tidas como “proibidas”. Elas abordam ainda o medo de forma artística e estética, permitindo que os leitores o compreendam e o ressignifiquem em suas realidades, mediados por processos imaginativos e ficcionais.
