简要总结
This study evaluated the effects of parasternal block and wound site infiltration on postoperative pain in patients undergoing median sternotomy. Patients were allocated to receive parasternal block, wound site infiltration, or standard systemic analgesia. Salivary opiorphin levels and postoperative pain scores were assessed to compare analgesic effectiveness between the groups.
详细描述
This randomized prospective study included patients undergoing surgery through median sternotomy. The study compared three perioperative analgesic approaches: parasternal block, wound site infiltration, and standard systemic analgesia without local intervention at the surgical site.
Salivary samples were collected before surgery, after sternotomy, and during the postoperative period to measure opiorphin levels. Postoperative pain was assessed using visual analogue scale scores, and additional analgesic requirement, opioid consumption, extubation time, intensive care unit stay, and adverse effects such as nausea and vomiting were recorded.
