Prospective randomized study comparing outcome of myocardial protection with Del-Nido Cardioplegia versus Saint Thomas Cardioplegia in adult cardiac surgical patients

Objectives: To compare the effectiveness of Del-Nido cardioplegia as myocardial protective agent with Saint Thomas cardioplegia in adult cardiac surgical patients. Methods: This prospective randomized study was conducted in cardiac surgery department of Bahawal Victoria hospital Bahawalpur, from October 2020 to March 2021. Eighty adult patients who underwent primary Isolated coronary artery bypass grafting (CABG) or isolated Valve surgery requiring cardiopulmonary bypass were randomly divided into Del Nido (DN, n=40) and Saint Thomas (ST, n=40) groups. Data regarding operative and post-operative variables such as cardiopulmonary bypass (CPB) and aortic cross clamp (AXC) times, inotropic requirements, resumption of sinus rhythm, need for electrical defibrillation, post-operative CKMB, blood requirement and ICU stay were noted. Results: CPB and AXC times were statistically insignificantly different. Resumption of Sinus rhythm was seen significantly in more patients of DN group (95%) than in ST group (72.5%) [p-value 0.05]. Less patients of DN group (5%) were candidates of electrical defibrillation than ST group (17.5%) [p-value <0.001). Post- operative CKMB values were significantly lower in DN group as compared to ST group (30.5±22.6 IU vs 50.5±50.28 IU, p value.008). Blood transfusion was significantly lower in DN group; 50% versus 80% in ST group (p-value 0.005). Ventilation time was significantly less in DN group than ST group (165.95±48.09 minutes versus 165.95±48.09 minutes respectively, p-value 0.03). While ICU stay was also less in DN group; 5.2±0.8 days versus 6.05±1.6 days in ST group (p-value 0.003). Conclusion: Del-Nido cardioplegia is a reliable and better myocardial protective agent than Saint Thomas cardioplegia in adult cardiac surgical procedures. doi: https://doi.org/10.12669/pjms.38.3.4730 How to cite this:Rizvi MFA, Yousuf SMA, Younas A, Baig MAR.

The Effect of Improving Preoperative Sleep Quality on Perioperative Pain by Zolpidem in Patients Undergoing Laparoscopic Colorectal Surgery: A Prospective, Randomized Study

Background and Objectives. Opioids are essential in pain management after laparoscopic colorectal surgery while large dose may induce constipation and pneumonia. Ample evidence has demonstrated that postoperative analgesia can improve sleep quality. But the effects of improvement in sleep quality on postoperative pain have yet to be determined. The aim of this study was to investigate the effect of improving preoperative sleep quality by zolpidem on intraoperative analgesia and postoperative pain. Methods. A prospective, randomized study was conducted with 88 patients undergoing laparoscopic colorectal surgery. The experimental group (S group, n = 44) was given 10 mg of zolpidem tartrate one night before the surgical procedure, while no medication was given to the control group (C group, n = 44). The primary outcome was the intraoperative remifentanil consumption. Sufentanil consumption, average patient-controlled analgesia (PCA) effective press times, the visual analog scale (VAS) scores, and incidences of postoperative nausea and vomiting (PONV) were recorded at 6 h (T1), 12 h (T2), and 24 h (T3) postoperatively. Results. The intraoperative remifentanil consumption was significantly lower in the S group than that in the C group ( p < 0.01 ). Sufentanil consumption at 6 h and 12 h postoperatively was significantly lower in the S group than that in the C group ( p < 0.05 ); average PCA effective press times and VAS scores, at 6 h and 12 h postoperatively, were significantly lower in the S group than those in the C group ( p < 0.01 ); differences between groups 24 h postoperatively were not significant. No significant between-group difference was noted in the incidence of nausea and vomiting. Conclusion. Improving patients’ sleep quality the night before surgical procedure by zolpidem can decrease the usage of intraoperative analgesics and reduce postoperative pain.
