Study Overview
Brief Summary
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.
Detailed Description
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.

Arms & Interventions
Slow PACE arm
The intervention consists of performance of pre-trained guided Slow PACE breathing by the patient at induction of anesthesia for breast cancer surgery.
Intervention: pre-trained guided slow paced breathing (~6 breaths per minute) (Behavioral)
Control arm
Care as usual
Outcomes
Primary Outcomes
Peri operative anxiety
Time Frame: 2 weeks
The present study aims to examine the effects of pre-trained guided Slow PACE 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. The total score ranging from 20 to 80. Higher scores indicate higher levels of anxiety symptoms. A cut-off score of 40 is commonly used to define probable clinical levels of anxiety.
Secondary Outcomes
- patient satisfaction(5 minutes on postoperative day 1)
- Anxiety trait scored by Spielberger's State Anxiety Inventory (STAI-T)13 at baseline(once at baseline, duration 10 minutes)
- need of hypnotics during induction(10 minutes)
- post-operative pain(post-operative on recovery (1-2hours))
- postoperative nausea and vomiting (PONV)(post-operative on recovery (1-2hours))
- mean blood pressure before induction(10 minutes)
- post-operative need of opioids(post-operative on recovery (1-2hours))
- Hospital Anxiety and Depression Scale (HADS-A)(once at baseline, duration 10 minutes)
