ABSTRACT
INTRODUCTION:
New-onset postoperative atrial fibrillation (POAF) is a common complication following cardiac surgeries. N-acetylcysteine (NAC) showed a significant reduction in the incidence of POAF. This review aimed to systematically summarize and Meta-analyze data from previously published Randomized Controlled Trials (RCTs). EVIDENCE ACQUISITION Electronic databases PubMed, Cochrane, Embase, Scopus, and Web of Science were searched. Data was extracted and the quality of the included studies was assessed. A random-effects DerSimonian Laird model was employed for meta-analysis. EVIDENCESYNTHESIS:
Fifteen RCTs were included in this study (NAC, N.=940; control, N.=935). In the NAC group, 16.38% developed POAF compared with 23.53% in the control group. NAC supplementation was associated with a decreased incidence of POAF in patients undergoing cardiothoracic surgery (RR 0.69; 95% CI 0.52, 0.91; P=0.008). Meta-regression of randomized trial data showed that the incidence of POAF was not related to the NAC dose (P=0.439). A subgroup analysis in terms of the time of NAC administration revealed that preoperative and postoperative NAC administration was the only subgroup that demonstrated a statistically significant difference (RR 0.48, 95% CI 0.32, 0.71; P=0.0003) compared with placebo and showed no heterogeneity.CONCLUSIONS:
Atrial fibrillation is a significant postoperative complication, particularly in cardiothoracic surgery. This study highlights the need for further research on optimal NAC dosing and timing, with evidence suggesting that preoperative and postoperative NAC administration may significantly decrease postoperative atrial fibrillation in cardiothoracic surgery patients, although limitations and variability in study designs need to be considered.
