Guided Breathing VR Reduces Opioid Use Post-PTBD in Cancer Patients by 64%

This randomized controlled trial evaluated the analgesic potential of guided breathing virtual reality (VR) in managing pain for cancer patients undergoing percutaneous transhepatic biliary drainage (PTBD). The study involved 45 patients who were randomly assigned to either a VR with guided deep breathing group (VRBG, n=22) or a conventional VR without breath guidance group (VROG, n=23). Both groups experienced two 7-minute VR sessions with calming visuals and narration, while VRBG received additional prompts for slow, rhythmic breathing. The primary endpoint was opioid consumption on the day following PTBD. Results showed that the VRBG group had significantly lower opioid consumption compared to the VROG group, with mean morphine milligram equivalents of 20.25 vs. 56.61 (P=0.044). No significant difference was observed in opioid use on the day of the procedure. Secondary endpoints included patient satisfaction and willingness to reuse VR, which were comparable between groups. Safety was assessed, revealing that mild adverse events were infrequent and self-limiting. These findings suggest that incorporating structured breathing guidance into VR may enhance its analgesic effect and reduce opioid reliance after invasive procedures, offering a promising non-pharmacological adjunct in cancer pain management.

This study involves cancer patients who are undergoing a procedure called percutaneous transhepatic biliary drainage, which can cause pain. Researchers tested two types of virtual reality experiences: one that included guided breathing to help relax and one that did not. They found that patients who used the virtual reality with breathing guidance needed less pain medication the day after the procedure compared to those who used the regular virtual reality. This suggests that using guided breathing in virtual reality might help patients feel less pain and rely less on strong medications. However, both groups reported similar satisfaction with their experience. It's important to note that while this method showed promise, more research is needed to confirm these results and understand how best to use it in pain management for cancer patients.
