CONTEXT
Various predictors have been used to predict diabetic patients who are likely to have increased ventilatory hours and an increased length of stay (LOS) in the Intensive Care Unit (ICU) as well as in the hospital after undergoing coronary artery bypass grafting (CABG) surgery, for example, glycosylated hemoglobin (HbA1c). The authors propose a simple bed-side test, i.e., the prayer sign to predict increased ventilatory hours and increased length of ICU and hospital stay.
AIMS
The aim of the present study was to assess whether any association exists between a positive prayer sign and increased ventilatory hours, length of ICU and hospital stay after CABG surgery in diabetic patients.
SETTINGS AND DESIGN
This prospective observational study was conducted in a 650-bedded tertiary cardiac center.
SUBJECTS AND METHODS
A total of 501 diabetic patients were recruited in the study over a period of 1 year. Group P consisted of 121 patients with prayer sign positive, whereas Group N consisted of 380 patients with prayer sign negative. HbA1c levels, ventilatory hours, LOS in the postoperative ICU and hospital were compared.
STATISTICAL ANALYSIS USED
Unpaired Student's t-test was used to compare the data.
RESULTS
The mean HbA1c levels in Group P were 8.01 ± 2.28% as compared to 6.52 ± 2.46% in Group N (P < 0.0001). The mean ventilatory hours in Group P were 9.52 ± 6.46 h, and in Group N were 7.42 ± 8.01 h (P = 0.013). Whereas, the mean length of ICU stay and hospital stay in Group P was 156.42 ± 32.66 h (6.51 ± 1.36 days) and 197.36 ± 32.46 h (8.22 ± 1.35 days), respectively, it was 121.12 ± 29.48 h (5.04 ± 1.22 days) and 178.52 ± 28.52 h (7.43 ± 1.18 days) in Group N (P < 0.0001).
CONCLUSIONS
A positive prayer sign is a useful bedside test for predicting increased ventilatory hours and increased length of ICU and hospital stay after CABG surgery.
背景
多种预测指标已被用于预测糖尿病患者在接受冠状动脉搭桥术（CABG）后，在重症监护病房（ICU）以及医院中可能会有更长的通气时间和住院时间，例如糖化血红蛋白（HbA1c）。作者提出了一种简单的床边检查方法，即祈祷征，用于预测通气时间延长以及ICU和医院住院时间延长。
目的
本研究的目的是评估糖尿病患者CABG术后祈祷征阳性与通气时间延长、ICU和医院住院时间延长之间是否存在关联。
设置与设计
这项前瞻性观察性研究在一家拥有650张床位的三级心脏中心进行。
研究对象与方法
在1年的时间里，共招募了501例糖尿病患者。P组由121例祈祷征阳性患者组成，而N组由380例祈祷征阴性患者组成。比较两组患者的糖化血红蛋白水平、通气时间、术后在ICU和医院的住院时间。
统计分析方法
采用非配对学生t检验比较数据。
结果
P组糖化血红蛋白平均水平为8.01±2.28%，而N组为6.52±2.46%（P<0.0001）。P组平均通气时间为9.52±6.46小时，N组为7.42±8.01小时（P=0.013）。P组在ICU和医院的平均住院时间分别为156.42±32.66小时（6.51±1.36天）和197.36±32.46小时（8.22±1.35天），N组分别为121.12±29.48小时（5.04±1.22天）和178.52±28.52小时（7.43±1.18天）（P<0.0001）。
结论
祈祷征阳性是预测CABG术后通气时间延长以及ICU和医院住院时间延长的一种有用的床边检查方法。
