The aim of this study was to evaluate the effect of a virtual reality video on preoperative anxiety, hemodynamic parameters, and patient satisfaction in patients undergoing septorhinoplasty.

This was a prospective, observational cohort trial. Forty patients between the ages of 18–65 who were scheduled for elective septorhinoplasty, with an American Society of Anesthesiologists (ASA) physical status I–II were included in the study. Patients experienced a 15-minute virtual reality (VR) video via a phone using a VR device. A three-dimensional, 360° video depicted the beauty of nature and was accompanied by meditation music. Patients’ oxygen saturation values, heart rate, and blood pressure were monitored and recorded. Using the State-Trait Anxiety Inventory scale, anxiety scores and hemodynamic parameters were compared before and after VR application.

Median anxiety scores decreased significantly from 40.5 to 34 (p < 0.001). VR also had positive effects on hemodynamic parameters.

VR reduces preoperative anxiety and has positive effects on hemodynamic parameters in patients undergoing septorhinoplasty. We anticipate that VR will be increasingly used as a non-pharmacological preoperative approach in the future.

O objetivo deste estudo foi avaliar o efeito de um vídeo de realidade virtual na ansiedade pré-operatória, parâmetros hemodinâmicos e satisfação do paciente em pacientes submetidos a septorrinoplastia.


Este foi um estudo de coorte prospectivo e observacional. Quarenta pacientes com idade entre 18 e 65 anos agendados para septorrinoplastia eletiva, com estado físico I-II da American Society of Anesthesiologists (ASA) foram incluídos no estudo. Os pacientes experimentaram um vídeo de realidade virtual (RV) de 15 minutos por telefone usando um dispositivo de realidade virtual. Um vídeo tridimensional de 360° retratava a beleza da natureza e era acompanhado por música de meditação. Os valores de saturação de oxigênio, frequência cardíaca e pressão arterial dos pacientes foram monitorados e registrados. Usando a escala State-Trait Anxiety Inventory, os escores de ansiedade e os parâmetros hemodinâmicos foram comparados antes e depois da aplicação da RV.


Os escores medianos de ansiedade diminuíram significativamente de 40,5 para 34 (p < 0,001). A RV também teve efeitos positivos nos parâmetros hemodinâmicos.


A RV reduz a ansiedade pré-operatória e tem efeitos positivos nos parâmetros hemodinâmicos em pacientes submetidos à septorrinoplastia. Prevemos que a RV será cada vez mais usada como uma abordagem pré-operatória não farmacológica no futuro.
