Abstract
BackgroundThis study aimed to investigate the effect of relaxation therapy on hypoxia during intravenous propofol anesthesia in patients with pre-operative anxiety.MethodsTwo-hundred and eighty patients were randomly categorized in the experimental group (relaxation therapy group) and control group. The Spielberger State-Trait Anxiety Inventory (S-STAI) was administered 30 to 60 min pre-operatively to assess the patient's current anxiety status and select appropriate patients. Patients in the experimental group received pre-surgical relaxation therapy. Decrease in oxygen saturation during the procedure was recorded for each patient group, and the relevant data were compared between the two groups.ResultsThe basic S-STAI scores of the experimental and control groups were 56.88 ± 2.91 and 57.27 ± 3.56, respectively (p = 0.331). The difference was not statistically significant. The incidence of hypoxia in the experimental group during painless artificial abortion [routine blood oxygen saturation (SpO2) <95%, duration >15 s] decreased from 30 to 12.3%.ConclusionRelaxation therapy may effectively reduce the incidence of hypoxia during painless artificial abortion by using less dose of propofol. It may help patients relieve their anxiety and improve perioperative safety.Trial RegistrationChinese Clinical Trial Registry (ChiCTR2000032109).

This study focused on the effect of relaxation therapy on hypoxia caused by intravenous propofol anesthesia in patients with preoperative anxiety
Summary
Pre-operative anxiety is a psychological reaction before surgery. It manifests as discomfort, apprehension, and fear [1]. The incidence of pre-operative anxiety in adult patients can be as high as 80% [8]. Anxiety is an independent risk factor for intraoperative hypoxia [10]. Patients who underwent painless artificial abortion in this study were at a high risk of pre-operative anxiety. Relaxation therapy can be used to alleviate anxiety and reduce the incidence of intraoperative hypoxia. This study aimed to evaluate whether relaxation therapy can reduce the incidence of intraoperative hypoxia among patients with pre-operative anxiety before undergoing painless artificial abortion. This study aimed to investigate the effect of relaxation therapy on hypoxia during intravenous propofol anesthesia in patients with pre-operative anxiety
