Management and clinical outcomes of cardiogenic shock in King Abdulaziz University Hospital: A retrospective study.

OBJECTIVES: To assess frequencies of various management approaches in cardiogenic shock (CS) and their clinical outcomes. Cardiogenic shock is a state of organ hypoperfusion and hypoxia caused by cardiac failure. METHODS: In this retrospective record review, we assessed the presentations, vital signs, laboratory readings, and treatments for 188 consecutive CS inpatients from 2010-2021. Patients were labeled as "ischemic CS" or "non-ischemic CS" based on the occurrence of myocardial infarction as the precipitating cause, and "post-operative CS" if they had undergone cardiac surgery. In-hospital mortality was the primary endpoint of the study. RESULTS: We identified 118 (62.8%) ischemic, 64 (34%) non-ischemic, and 6 (3.2%) postoperative CS patients. The study population had a high mortality rate (85.1%). Logistic regression analysis revealed that dopamine (p=0.040) and epinephrine (p=0.001) were independent predictors of mortality, while dobutamine (p=0.004) and digoxin (p=0.044) associated with increased survival. No significant association with mortality was found between either PCI or IABP. No significant difference in mortality was observed between CS subgroups. CONCLUSION: Variations in outcomes occurred with different medications. Mortality was higher in patients receiving dopamine or epinephrine and lower in those receiving dobutamine or digoxin. Implementation of clinical trials for investigation of the mortality benefit observed with dobutamine can serve towards formulation of new guidelines for improvement of CS mortality rates.

Incidence and Risk Factors for Retinal Detachment Following Cataract Surgery at a Tertiary Center in Jeddah, Saudi Arabia.

Introduction The incidence of retinal detachment in the general population is 0.08%, it has been reported to reach 0.7% or higher following cataract surgery. One of the most important risk factors for retinal detachment is posterior capsular rupture during cataract surgery. Additional risk factors include high myopia, history of ocular trauma, young age, male sex, and diabetes. In this study, we aimed to investigate the incidence and risk factors of retinal detachment following cataract surgery in patients treated at our hospital. Materials and methods This retrospective cohort study was conducted at King Abdulaziz University Hospital (KAUH), a tertiary center in Jeddah, Saudi Arabia. The medical records of 365 patients (365 eyes) who underwent cataract surgery from 2017 to 2021 were reviewed. Results The average age of the 365 patients was 63 years, and 47.7% (n=174) of patients were male. The incidence of retinal detachment was 3.3% (n=12). The risk of RD was 2.8 times higher for the right eye than for the left eye. The incidence of RD was significantly more in eyes with intraoperative posterior capsular rupture, zonular dehiscence, corneal trauma, and surgery combined with anterior vitrectomy than in other eyes. The most common complication of cataract surgery is corneal edema, which was observed in 22.7% of the eyes; our analysis revealed a significant relationship between corneal edema and the duration of surgery. Conclusion In our study, we highlighted the higher incidence of retinal detachment compared to those in other studies; most cases occurred one month postoperatively.
