Cardiovascular Surgical Procedures

Coronary artery bypass grafting is the most commonly performed surgical procedure among cardiovascular diseases. Nursing care for patients undergoing cardiac surgery involves a process that includes preoperative preparation and subsequent close monitoring of neurological, cardiac, respiratory, vascular status, kidney function, and pain. Sleep disturbances are observed after cardiac surgery. Sleep plays a critical role in the body's maintenance, repair, and renewal processes. Improved sleep can reduce patient agitation and decrease the risk of delirium. The presence of delirium leads to increased care requirements and prolonged hospital stays, which in turn raises hospital costs. Enhancing sleep quality and preventing delirium after surgery have positive effects on clinical patient outcomes. This study is designed to determine the effects of using eye masks and/or earplugs on sleep quality and delirium in patients undergoing coronary artery bypass grafting during nighttime sleep. This research is a randomized controlled clinical trial.

In this randomized trial, the investigators will test the hypothesis that combining regional analgesia techniques-which have the potential to improve the quality of postoperative recovery following median sternotomy-with PIFB will accelerate recovery. Additionally, it is anticipated that RIFB, an alternative fascial plane block, will demonstrate non-inferior (at least as effective as) performance compared to RSB, thereby providing flexibility and ease of application in clinical practice.

The aim of this observational cohort study is to evaluate the effect of high-dose versus low-dose propofol infusion on the incidence of postoperative nausea and vomiting (PONV) in patients undergoing coronary artery bypass grafting (CABG). The study also seeks to assess the predictive performance of the Apfel and Koivuranta risk scores for PONV in the cardiac surgery population. The primary objective of this study is to determine the impact of routinely administered high-dose propofol on the incidence and severity of PONV in CABG patients. The secondary objective is to evaluate the need for antiemetic therapy during the intensive care unit stay. The investigators will compare patients receiving high-dose propofol with those receiving low-dose propofol to determine whether the antiemetic effect of propofol is dose-dependent. Participants will be asked to: Allow PONV assessments to be performed during the first 24 hours postoperatively, Provide permission for the collection of clinical data (including demographic characteristics, risk scores, opioid consumption, etc.) for research purposes.

This study is a multicenter, randomized controlled, double-blind, placebo-controlled parallel trial designed to evaluate the effect of perioperative supplementation with Compound Vitamin B on patients undergoing cardiovascular surgery. A total of 1,000 patients aged 18-80 years who are scheduled to receive cardiovascular surgeries such as coronary artery bypass grafting (CABG) and valve replacement will be enrolled. They will be randomly assigned at a 1:1 ratio to either the experimental group (perioperative supplementation with Compound Vitamin B tablets, once daily from 3 days before surgery to 6 months after surgery) or the control group (oral placebo), with both groups receiving standardized perioperative treatment.
