Magnesium, known for its stabilizing effect on cell membranes, has shown promise in preventing postoperative atrial fibrillation. This study aimed to assess the impact of intravenous magnesium infusion in preventing atrial fibrillation after off-pump coronary artery bypass grafting, where maintaining stable cell membranes is crucial in averting this complication. Methods: A cross-sectional study was conducted at the Department of Cardiac Surgery, Bangabandhu Sheikh Mujib Medical University, from March 2020 to February 2022. Sixty-six patients who underwent off-pump coronary artery bypass grafting were enrolled and divided into two groups. Group A (n = 33) received intravenous magnesium sulfate (10 mmol/2.47gm) for three days after surgery, while Group B (n = 33) did not receive magnesium sulfate. Postoperative atrial fibrillation occurrence in the Intensive Care Unit (ICU) within three days after surgery was evaluated using convenient sampling. Statistical analysis was performed with SPSS version 26.0, utilizing independent Student’s t-test for continuous data and Chi-square and Fisher’s exact test for categorical data. A p-value of ≤0.05 was considered statistically significant. Results: No significant differences in age or gender were observed between the two groups. Group B exhibited significantly lower magnesium levels than Group A on the 0<sup>th</sup>, 1<sup>st</sup>, 2<sup>nd</sup>, and 3<sup>rd</sup> days post-surgery. Additionally, Group B experienced a higher incidence of postoperative atrial fibrillation, longer ICU stays, and two mortalities. The study did not detect any adverse effects associated with magnesium infusion. Conclusion: It has been demonstrated that administering magnesium intravenously after off-pump coronary artery bypass grafting can lower the chances of developing atrial fibrillation. This demonstrates the potential advantages of using magnesium as a preventative measure for postoperative atrial fibrillation in such cases.展开更多

Indeed, it is the main cause of high death rate and infant morbidity, neurologic deficiencies being one of them. Objective: From March 1st to September 30th, 2020, evaluate the fetal neuroprotection protocol using sulfate magnesium during births before thirty-three (33) weeks of amenorrhea at the University Health Centers (UHC) of Yalgado Ouedraogo and Bogodogo in Ouagadougou, Burkina Faso. Patients and Methods: It was a prospective cohort survey, exposed or unexposed. The exposed ones are from the UHC of Yalgado Ouedraogo, while the unexposed ones are from the UHC of Bogodogo. Analysis of the results showed 87 newborns from the exposed and 180 from the unexposed. The mortality rate, as well as neonatal neurologic complications, was higher with unexposed than with exposed. Although antenatal exposure to magnesium sulfate was not statistically associated with mortality and morbidity in newborns at a threshold of 0.05%, it has shown an overall good neurological prognosis in newborns exposed. Conclusion: A survey of a large sample of the population would be relevant in order to better assess the determinants of this influence. Proposition: In light of the results, the use of magnesium sulfate for neuroprotective purposes could be considered in our countries.展开更多

文摘Background: Atrial fibrillation commonly occurs following cardiac surgery, particularly after coronary artery bypass grafting. Magnesium, known for its stabilizing effect on cell membranes, has shown promise in preventing postoperative atrial fibrillation. This study aimed to assess the impact of intravenous magnesium infusion in preventing atrial fibrillation after off-pump coronary artery bypass grafting, where maintaining stable cell membranes is crucial in averting this complication. Methods: A cross-sectional study was conducted at the Department of Cardiac Surgery, Bangabandhu Sheikh Mujib Medical University, from March 2020 to February 2022. Sixty-six patients who underwent off-pump coronary artery bypass grafting were enrolled and divided into two groups. Group A (n = 33) received intravenous magnesium sulfate (10 mmol/2.47gm) for three days after surgery, while Group B (n = 33) did not receive magnesium sulfate. Postoperative atrial fibrillation occurrence in the Intensive Care Unit (ICU) within three days after surgery was evaluated using convenient sampling. Statistical analysis was performed with SPSS version 26.0, utilizing independent Student’s t-test for continuous data and Chi-square and Fisher’s exact test for categorical data. A p-value of ≤0.05 was considered statistically significant. Results: No significant differences in age or gender were observed between the two groups. Group B exhibited significantly lower magnesium levels than Group A on the 0<sup>th</sup>, 1<sup>st</sup>, 2<sup>nd</sup>, and 3<sup>rd</sup> days post-surgery. Additionally, Group B experienced a higher incidence of postoperative atrial fibrillation, longer ICU stays, and two mortalities. The study did not detect any adverse effects associated with magnesium infusion. Conclusion: It has been demonstrated that administering magnesium intravenously after off-pump coronary artery bypass grafting can lower the chances of developing atrial fibrillation. This demonstrates the potential advantages of using magnesium as a preventative measure for postoperative atrial fibrillation in such cases.

Conclusion: A survey of a large sample of the population would be relevant in order to better assess the determinants of this influence. Proposition: In light of the results, the use of magnesium sulfate for neuroprotective purposes could be considered in our countries.
文摘Background Constipation is a common problem in children with spastic cerebral palsy(sCP)with a prevalence that reaches 75%.We hypothesized that treating constipation in those children will improve their health and shorten time spent in daily care.Our aim was to evaluate the efficacy and safety of oral magnesium sulfate for treating chronic constipation in children with sCP.Methods A prospective,double-blinded randomized control trial was carried out involving 100 children aged 2-12 years with sCP(level Ⅲ-Ⅴ of the Gross Motor Functional Classification system)and chronic constipation.They were followed up in the Pediatric neurology clinic,Children's hospital,Ain Shams University,May 2017-January 2019.The intervention group(O-Mg)received oral magnesium sulfate 1 mL/kg/day daily for 1 month compared to the placebo.Outcome measures were constipation improvement and decrease in bowel evacuation time after 1 month.Results Initially,weekly bowel movements,constipation scores and stool consistency were comparable in both groups.After 1 month of regular administration of oral magnesium sulfate,the constipation score,stool frequency and consistency improved compared to the placebo group(P<0.001).Effective safe treatment was achieved in 31(68%)and 4(9.5%)patients in the O-Mg and placebo groups,respectively(RR,2.95;95%CI 2.0-4.5)(P<0.001).Painful bowel evacuation attempts spent by mothers decreased from 25(55.6%)of the cases initially to 10(22%)cases after one month in the O-Mg group(P=0.001).In contrast,in the placebo group,the decrease went from 21(50%)cases initially to 18(42.9%)after 1 month and was not significant(P=0.5).Conclusions Oral magnesium sulfate seems effective in alleviating chronic constipation and pain experience in children with sCP.Consequently,saving maternal time spent in daily bowel evacuation attempts.
