Parasternal Block Versus Wound Infiltration for Pain After Median Sternotomy:A Salivary Opiorphin-Based Study

2026年5月30日 更新者：Mehmet Akif Yilmaz、Ataturk University

Determination of the Effect of Parasternal Block Versus Wound Site Infiltration on Postoperative Pain Levels by Salivary Opiorphin Levels in Patients Undergoing Median Sternotomy: A Randomized Prospective Study

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.

详细说明

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.

主要结果指标

结果测量
措施说明
大体时间
Change in Salivary Opiorphin Level
大体时间：Baseline, 3 minutes after sternotomy, and postoperative 6 hours
Salivary opiorphin levels were measured using ELISA to evaluate the analgesic effect of the study interventions.
Baseline, 3 minutes after sternotomy, and postoperative 6 hours

次要结果测量

结果测量
措施说明
大体时间
Postoperative Pain Intensity Assessed by the Visual Analogue Scale
大体时间：At 1, 2, 4, 8, 12, and 24 hours after extubation
Postoperative pain intensity was assessed using the Visual Analogue Scale. The scale ranges from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate worse postoperative pain.
At 1, 2, 4, 8, 12, and 24 hours after extubation
Additional Analgesic Requirement
大体时间：Within the first 24 hours after extubation
The need for rescue analgesia was recorded during the postoperative follow-up period.
Within the first 24 hours after extubation
Total Opioid Consumption
大体时间：Within the first 24 postoperative hours
Total opioid consumption delivered by patient-controlled analgesia was recorded.
Within the first 24 postoperative hours
Extubation Time
大体时间：Immediately after surgery until tracheal extubation, assessed up to 24 hours postoperatively
Time to extubation was defined as the duration from the end of surgery to tracheal extubation and was recorded in minutes.
Immediately after surgery until tracheal extubation, assessed up to 24 hours postoperatively
Intensive Care Unit Length of Stay
大体时间：From postoperative intensive care unit admission until intensive care unit discharge, assessed up to 7 days postoperatively
Intensive care unit length of stay was defined as the duration from admission to the intensive care unit after surgery until discharge from the intensive care unit and was recorded in hours.
From postoperative intensive care unit admission until intensive care unit discharge, assessed up to 7 days postoperatively
Postoperative Nausea and Vomiting
大体时间：Within the first 24 postoperative hours
Postoperative nausea and vomiting were recorded as adverse effects.
Within the first 24 postoperative hours
