Key result
A comprehensive pain control strategy significantly reduced the average numerical rating scale pain score during the first 3 days postoperatively compared to the previous strategy (0.82 vs 2.40, p<0.01) in patients undergoing minimally invasive mitral valve repair.
Why the study?
To assess the effect of a comprehensive strategy to reduce pain after minimally invasive mitral valve repair through a right mini-thoracotomy.

Does a comprehensive pain control strategy reduce postoperative pain in patients undergoing minimally invasive mitral valve repair?
A comprehensive pain control strategy significantly reduces postoperative pain and the need for additional analgesics in patients undergoing minimally invasive mitral valve repair.
May support multimodal analgesia after minimally invasive mitral valve repair; hypothesis-generating without randomized confirmation.
PURPOSE: The effect of our comprehensive strategy to reduce pain after minimally invasive mitral valve repair through a right mini-thoracotomy was assessed retrospectively. METHODS: Our comprehensive strategy constituted the following: planned rib cutting to avoid rib injury, sufficient intercostal muscle division to mobilize the cut rib, limiting the number of intercostal ports, avoiding nerve entrapment, continuous extra-pleural intercostal nerve block, and regular use of oral non-steroidal anti-inflammatory drugs. We compared patients treated with this comprehensive strategy (Group S, n = 13) and patients before this strategy was implemented (Group C, n = 13). We used a numerical rating scale (NRS) as a pain scale during the first 3 days postoperatively. RESULTS: The average NRS was significantly lower in Group S (0.82 ± 0.49) than in Group C (2.40 ± 1.46) (P <0.01). The maximum NRS was also significantly lower in Group S (3.23 ± 1.17) than in Group C (5.69 ± 2.43) (P <0.01). The number of patients using additional single-dose analgesic were significantly less in Group S (23.1%) than in Group C (84.6%) (P <0.01). CONCLUSION: Our comprehensive pain control strategy effectively reduced postoperative pain in minimally invasive mitral valve repair.

Hosono et al. (2021) conducted a cohort in Minimally invasive mitral valve repair (n=26). Comprehensive pain control strategy vs. Previous standard pain control strategy was evaluated on Average numerical rating scale (NRS) score during the first 3 days postoperatively (p=<0.01). A comprehensive pain control strategy significantly reduced the average numerical rating scale pain score during the first 3 days postoperatively compared to the previous strategy (0.82 vs 2.40, p<0.01) in patients undergoing minimally invasive mitral valve repair.
