Peri-operative Slow-paced Breathing to Reduce Anxiety in Breast Cancer Surgery Patients

Overview

The purpose of this single-center trial is to examine the effects of a slow-breathing technique performed at induction of anesthesia in patients undergoing surgery for breast cancer on anxiety, scored by Spielberger's State-Trait Anxiety Inventory, state scale (STAI-S),13 compared to usual care.

Rationale: In the perioperative period anxiety for anesthesia and the surgical procedure is common. Breast cancer surgery patients have a higher level of anxiety compared to other patients undergoing (cancer) surgery. Relaxation techniques, like breath focus with deep belly breathing are easy to learn and can have a beneficial effect on postoperative anxiety, pain, and postoperative nausea and vomiting (PONV), but the quality of evidence is low. Slow paced breathing at a frequency of 6 breaths per minute can possibly increase vagal activation, decrease anxiety, reduce mean blood pressure, and postoperative pain. The investigators aim to apply a pre-trained slow paced breathing technique at induction of anesthesia for surgery, to reduce perioperative anxiety and to explore effects on pre-operative blood pressure, per-operative need of hypnotics, postoperative pain and opioid use, PONV and patient satisfaction. Objective: This study aims to examine the effects of guided slow paced breathing performed at induction of anesthesia in patients undergoing surgery for breast cancer on anxiety, scored by Spielberger's State-Trait Anxiety Inventory, State scale (STAI-S), compared to usual care. Study design: Single center, two-group, prospective, randomized controlled trial Study population: patients scheduled for surgery for breast cancer in the Antoni van Leeuwenhoek Hospital. Intervention: Performance of pre-trained guided slow paced breathing by the patient at induction of anesthesia for breast surgery. Main study parameters: Anxiety scored by Spielberger's State Anxiety Inventory (STAI-S) Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are no risks related to the intervention. Participants randomized in the intervention group are trained in slow paced breathing after inclusion and asked to practice the technique daily until the day of surgery. All participants are asked to complete three questionnaires at baseline, and two short questionnaires on the day of surgery and at day 1.
